Cooking a broccoli, mushroom, and cheddar quiche is a delightful way to combine savory flavors and creamy texture, but achieving the perfect consistency requires attention to timing. Typically, this quiche bakes in a preheated oven at 375°F (190°C) for 35 to 45 minutes, depending on your oven and the depth of your pie dish. The key is to ensure the filling is set but still slightly jiggly in the center, as it will continue to cook as it cools. Overbaking can result in a dry, rubbery texture, so it’s essential to monitor the quiche closely during the last 10 minutes of cooking. A golden-brown crust and a knife inserted near the center coming out clean are reliable indicators that your quiche is ready to enjoy.

Preparation Time: Includes chopping veggies, grating cheese, and preparing the pie crust
Begin by gathering all your ingredients to streamline the preparation process. For a broccoli mushroom cheddar quiche, you’ll need broccoli, mushrooms, cheddar cheese, eggs, milk, and a pie crust. Start with the vegetables: wash the broccoli thoroughly, then chop it into small, bite-sized florets. This task typically takes about 5–7 minutes, depending on the size of the broccoli head. Next, clean the mushrooms by gently wiping them with a damp cloth or brushing off any dirt. Slice the mushrooms thinly, which should take another 3–5 minutes. Having both vegetables prepped and ready ensures they cook evenly in the quiche.
While the vegetables are being prepared, focus on the cheese. Grating cheddar cheese is a straightforward but time-consuming step, especially if you’re grating it by hand. Plan for 5–8 minutes to grate about 1.5 to 2 cups of cheddar, depending on the desired cheesiness of your quiche. If you’re using a food processor with a grating attachment, this time can be cut in half. Grating the cheese fresh ensures maximum flavor and meltiness in the quiche.
Preparing the pie crust is another essential step in the preparation process. If you’re using a store-bought pie crust, it’s as simple as unrolling it and fitting it into a 9-inch pie dish, which takes about 2–3 minutes. For a homemade crust, factor in additional time for mixing, rolling, and chilling the dough, which can add 20–30 minutes to your preparation. Once the crust is in the dish, you may want to prick the bottom with a fork and pre-bake it for 8–10 minutes at 375°F (190°C) to prevent a soggy base. This step is optional but recommended for a crispier crust.
As you chop the vegetables and grate the cheese, consider multitasking to save time. For example, while the pie crust is pre-baking (if you choose to do so), you can whisk together the eggs and milk for the quiche filling. This mixture typically requires 2–3 minutes to prepare. By overlapping tasks, you can keep the total preparation time efficient, generally ranging from 25 to 40 minutes, depending on whether you’re using a homemade or store-bought pie crust.
Finally, once all the components are ready, assemble the quiche by layering the chopped broccoli and mushrooms in the prepared crust, then pouring the egg and milk mixture over the top. Sprinkle the grated cheddar evenly across the surface. This final assembly step takes about 5 minutes. With all the preparation complete, your quiche will be ready to go into the oven, where it will bake for approximately 40–45 minutes at 375°F (190°C), or until the filling is set and the top is golden brown. Proper preparation ensures a delicious, well-structured quiche with minimal stress.

Baking Time: Typically 40-45 minutes at 375°F until the center sets
When preparing a broccoli, mushroom, and cheddar quiche, understanding the baking time is crucial for achieving the perfect texture and flavor. Baking Time: Typically 40-45 minutes at 375°F until the center sets is the golden rule for this dish. This timeframe ensures that the eggs are fully cooked, the vegetables are tender, and the cheese is melted and slightly golden on top. Preheat your oven to 375°F before placing the quiche inside to ensure even cooking from the start. The temperature is key, as it allows the quiche to cook through without burning the crust or overcooking the filling.
During the baking process, keep an eye on the quiche after the 35-minute mark. The center should set as the final indicator of doneness. A properly set quiche will jiggle slightly when shaken but should not appear wet or runny. If the edges start to brown too quickly, you can loosely cover them with aluminum foil to prevent burning while allowing the center to continue cooking. This technique ensures that both the edges and the center finish cooking at the same time.
The 40-45 minute range at 375°F is designed to accommodate variations in oven performance and the thickness of your quiche. If your quiche is deeper or contains extra ingredients, it may require closer to 45 minutes. Conversely, a thinner quiche might be ready in 40 minutes. Always prioritize the visual and textural cues over the timer to ensure perfection.
Once the quiche is done, remove it from the oven and let it rest for 10-15 minutes before slicing. This resting period allows the filling to firm up, making it easier to serve neat, clean slices. Baking Time: Typically 40-45 minutes at 375°F until the center sets is not just a guideline but a guarantee that your broccoli, mushroom, and cheddar quiche will emerge from the oven with a golden crust, a creamy interior, and a harmonious blend of flavors.
Finally, remember that every oven is unique, so it’s always a good idea to test the quiche’s doneness by inserting a knife into the center. If it comes out clean, your quiche is ready. By adhering to the 40-45 minute baking time at 375°F, you’ll ensure that your quiche is cooked to perfection, with a set center that’s the hallmark of a well-executed dish.

Cooling Period: Let it rest for 10-15 minutes before slicing
After removing your broccoli mushroom cheddar quiche from the oven, it’s crucial to allow it to rest for 10-15 minutes before slicing. This cooling period is not just a suggestion—it’s a key step to ensure the quiche holds its shape and texture. When you first take the quiche out, the filling is still hot and slightly soft, especially in the center. Letting it rest allows the eggs and cheese to set fully, creating a firm yet creamy consistency that won’t collapse or ooze when sliced. Skipping this step could result in a messy, uneven piece that doesn’t showcase the quiche’s layers of broccoli, mushrooms, and cheddar.
During the 10-15 minute cooling period, the quiche continues to cook gently from the residual heat of the crust and filling. This process helps the ingredients bond together, ensuring each slice holds its structure. The steam inside the quiche also redistributes, preventing excess moisture from pooling on the surface or making the crust soggy. Covering the quiche loosely with foil during this time can help retain heat without trapping moisture, but it’s not strictly necessary unless your kitchen is particularly cold.
Another benefit of the cooling period is that it allows the flavors to meld together. The earthy mushrooms, sharp cheddar, and tender broccoli need time to harmonize, creating a more cohesive and satisfying taste. Slicing too soon can disrupt this process, leaving you with a quiche that tastes good but lacks depth. Patience during this brief rest period pays off in both texture and flavor.
Practically speaking, the 10-15 minute rest also makes the quiche easier to handle. The crust firms up slightly, reducing the risk of it crumbling when you transfer the quiche to a serving plate or cut into it. If you’re serving the quiche warm, this cooling time brings it to an ideal temperature—not too hot to burn your mouth, but still comforting and inviting. It’s a small window of time that makes a big difference in the final presentation and enjoyment of your dish.
Finally, this cooling period is a great opportunity to prepare any accompaniments, such as a side salad or sauce, without feeling rushed. By the time you’re ready to slice the quiche, it will be perfectly set and ready to serve. Remember, the goal is to achieve clean, attractive slices that highlight the colorful ingredients inside. Rushing this step undermines the effort you’ve put into preparing the quiche, so treat the 10-15 minute cooling period as an essential part of the cooking process, not just an afterthought.

Ingredient Prep: Sauté mushrooms, blanch broccoli, and whisk eggs with milk
Ingredient Prep: Sauté Mushrooms
Begin by preparing the mushrooms, as they form the savory base of your quiche. Start by cleaning 8 ounces of button or cremini mushrooms. Gently wipe them with a damp cloth or paper towel to remove any dirt, avoiding rinsing them under water, which can make them soggy. Slice the mushrooms thinly and evenly to ensure they cook uniformly. Heat 1 tablespoon of olive oil or butter in a large skillet over medium heat. Once the oil is hot, add the mushrooms and a pinch of salt to draw out their moisture. Sauté for 5–7 minutes, stirring occasionally, until they are golden brown and their liquid has evaporated. This step concentrates their flavor and ensures they don't release excess moisture into the quiche. Transfer the sautéed mushrooms to a plate and set aside to cool slightly.
Ingredient Prep: Blanch Broccoli
Next, prepare the broccoli to retain its vibrant color and crisp-tender texture. Cut 2 cups of fresh broccoli florets into small, bite-sized pieces. Bring a medium pot of salted water to a rolling boil. Prepare a large bowl of ice water by filling it halfway with ice and topping it with cold water. Once the water is boiling, carefully add the broccoli florets and blanch them for 1–2 minutes. They should turn bright green but still remain slightly firm. Immediately transfer the blanched broccoli to the ice water bath to stop the cooking process. After 1 minute, drain the broccoli thoroughly and pat it dry with a clean kitchen towel or paper towels. Excess moisture can make your quiche soggy, so ensure the broccoli is as dry as possible before adding it to the quiche mixture.
Ingredient Prep: Whisk Eggs with Milk
The final step in ingredient prep is creating the egg and milk custard, which binds the quiche together. In a large mixing bowl, crack 4 large eggs and whisk them vigorously until the yolks and whites are fully combined. Gradually add 1 cup of whole milk (or half-and-half for a richer texture) while continuing to whisk. This ensures the eggs and milk are thoroughly incorporated, creating a smooth and creamy base. Add a pinch of salt, ¼ teaspoon of black pepper, and ¼ teaspoon of ground nutmeg (optional but recommended for depth of flavor). Whisk again to combine the seasonings evenly. This custard mixture should be light and frothy, ready to envelop the sautéed mushrooms, blanched broccoli, and shredded cheddar cheese in the next steps of assembling your broccoli mushroom cheddar quiche.
Combining Prepped Ingredients
With all ingredients prepped, you’re now ready to assemble the quiche. Preheat your oven to 375°F (190°C) and prepare a 9-inch pie crust (store-bought or homemade) by placing it on a baking sheet for easy handling. Evenly distribute the sautéed mushrooms and blanched broccoli over the bottom of the pie crust. Sprinkle 1 cup of shredded sharp cheddar cheese on top of the vegetables, ensuring an even layer. Slowly pour the whisked egg and milk mixture over the filling, allowing it to settle between the ingredients. Take care not to overfill the crust, as the custard will puff slightly during baking. This thorough prep work ensures each component of the quiche is perfectly cooked and harmoniously combined.
Final Notes on Prep
Proper ingredient prep is key to a successful quiche. Sautéing the mushrooms removes excess moisture and enhances their umami flavor, while blanching the broccoli preserves its color and texture. Whisking the eggs with milk creates a custard that is both light and rich, binding the quiche together. By taking the time to prep each ingredient thoughtfully, you set the stage for a quiche that is not only delicious but also visually appealing. Once assembled, your broccoli mushroom cheddar quiche will be ready to bake for 35–45 minutes, or until the custard is set and the top is golden brown. Enjoy the fruits of your prep work in every savory slice.

Storage Tips: Refrigerate leftovers for up to 3 days; reheat gently
When preparing a broccoli, mushroom, and cheddar quiche, it’s essential to consider how to store leftovers properly to maintain flavor and texture. After baking your quiche, allow it to cool to room temperature before storing. Placing a hot quiche directly into the refrigerator can raise the internal temperature of the fridge and potentially spoil other foods. Once cooled, cover the quiche tightly with aluminum foil or plastic wrap to prevent it from drying out or absorbing odors from other items in the refrigerator. Alternatively, you can transfer individual slices to airtight containers for easier portioning later.
Refrigerating your broccoli, mushroom, and cheddar quiche is the best way to preserve its freshness. Leftovers can be stored in the fridge for up to 3 days. Beyond this timeframe, the quiche may begin to lose its texture and flavor, and there’s a higher risk of bacterial growth. Ensure your refrigerator is set at or below 40°F (4°C) to keep the quiche safe to eat. Labeling the storage container with the date can help you keep track of how long it has been stored, making it easier to determine when it’s time to discard any remaining portions.
When you’re ready to enjoy your leftover quiche, reheating it gently is key to maintaining its creamy texture and preventing the crust from becoming soggy. Preheat your oven to 350°F (175°C) and place the quiche slice in an oven-safe dish. Cover it loosely with foil to retain moisture and prevent the top from burning. Reheat for 10–15 minutes, or until the quiche is warmed through. If you’re short on time, you can use a microwave, but be cautious—microwaving can sometimes make the crust rubbery. Heat the quiche in the microwave on medium power for 30-second intervals, checking after each interval to ensure it’s heated evenly.
For the best results, avoid reheating the quiche more than once, as this can affect its quality. If you have a large amount of leftover quiche, consider reheating only what you plan to eat at that time. This practice helps preserve the texture and flavor of the remaining portions. Additionally, if you notice any signs of spoilage, such as an off smell or visible mold, discard the quiche immediately, even if it’s within the 3-day storage window.
Finally, if you anticipate not finishing the quiche within 3 days, freezing is a great option. Wrap the quiche tightly in plastic wrap and then in aluminum foil before placing it in the freezer. Frozen quiche can last for up to 2 months. To reheat from frozen, thaw it overnight in the refrigerator and then follow the reheating instructions mentioned earlier. Proper storage and reheating techniques ensure that your broccoli, mushroom, and cheddar quiche remains delicious and safe to eat, whether enjoyed fresh or as leftovers.
