Prep Ingredients: Slice mushrooms, dice onions, mince garlic, and gather butter, oil, salt, and pepper
To begin preparing your sautéed mushrooms and onions, start by selecting fresh, firm mushrooms. Button, cremini, or shiitake mushrooms work well for this dish. Rinse the mushrooms gently under cold water to remove any dirt, then pat them dry with a paper towel. Properly drying the mushrooms is crucial as excess moisture can affect the sautéing process. Once dry, use a sharp knife to slice the mushrooms. Aim for uniform slices, about ¼ inch thick, to ensure even cooking. Thicker slices will give you a meatier texture, while thinner ones will cook faster and become more tender.
Next, turn your attention to the onions. Choose a medium-sized yellow or white onion for a balanced flavor. Peel the outer layer of the onion and cut off both ends. Place the onion cut-side down on your cutting board to stabilize it. Slice the onion in half from root to stem, then lay each half flat and make vertical cuts, being careful not to slice all the way through the root end. Finally, make horizontal cuts to dice the onion. The goal is to achieve small, even pieces that will cook evenly alongside the mushrooms.
Garlic is a key flavor component in this dish, so prepare it carefully. Peel the garlic cloves by smashing them lightly with the side of your knife or using a garlic peeler. Once peeled, mince the garlic finely. To do this, slice the clove thinly, then gather the slices and cut them in the opposite direction. Repeat this process until the garlic is finely minced. Minced garlic will infuse the dish with its aroma and flavor more effectively than larger pieces.
While you’re prepping the vegetables, gather the remaining ingredients: butter, oil, salt, and pepper. Butter adds richness and depth of flavor, while oil helps prevent the butter from burning at higher temperatures. Use a combination of 1 tablespoon of butter and 1 tablespoon of olive oil or another high-heat oil like avocado oil. Have your salt and pepper ready as well—seasoning is essential to enhance the natural flavors of the mushrooms and onions. Keep these ingredients within arm’s reach to ensure a smooth cooking process once your vegetables are prepped.
Finally, organize your workspace to streamline the cooking process. Place the sliced mushrooms, diced onions, and minced garlic in separate bowls or on a clean cutting board. Arrange the butter, oil, salt, and pepper near your stovetop. Having everything prepped and within reach will make sautéing the mushrooms and onions a seamless and enjoyable task. This preparation ensures that you can focus on the cooking technique without interruptions, resulting in a perfectly sautéed side dish.

Heat Pan: Use medium-high heat, add butter and oil to prevent burning
When preparing sautéed mushrooms and onions, the first step is to properly heat your pan, which sets the foundation for a successful dish. Begin by placing your skillet or frying pan on the stovetop and setting the heat to medium-high. This temperature is ideal because it provides enough heat to cook the vegetables quickly while allowing you to maintain control over the process. Medium-high heat ensures that the mushrooms and onions will develop a nice sear without burning, which is crucial for achieving that desirable caramelized flavor and texture.
Once the pan is on the heat, it’s essential to add both butter and oil to prevent burning. Butter adds richness and flavor to the dish, but it has a lower smoke point, meaning it can burn easily if used alone. To counteract this, combine it with a neutral oil, such as vegetable or canola oil, which has a higher smoke point. Start by adding about 1 tablespoon of oil and 1 tablespoon of butter to the pan. The oil will help the butter withstand the higher temperature, ensuring it doesn’t burn while still imparting its delicious flavor. Swirl the pan gently to coat the surface evenly.
Allow the butter and oil to heat until the butter has melted completely and begins to foam slightly. This is a sign that the pan is ready for the vegetables. You’ll notice the mixture starts to shimmer, indicating it’s hot enough to create immediate contact with the mushrooms and onions without sticking or burning. This step is critical because adding cold ingredients to a hot pan can cause the temperature to drop, leading to steaming instead of sautéing, which results in soggy vegetables rather than the desired golden-brown sear.
It’s important to monitor the pan closely during this stage. If the butter starts to brown too quickly or emits a nutty aroma, reduce the heat slightly to maintain control. The goal is to keep the fat hot but not smoking excessively. This balance ensures the mushrooms and onions cook evenly and develop a beautiful color without any burnt bits. Properly heating the pan with the right combination of butter and oil is key to achieving the perfect sauté.
Finally, once the pan is adequately heated and the butter-oil mixture is ready, you can proceed to add your sliced mushrooms and onions. The vegetables should sizzle gently as they hit the pan, a sign that the heat is just right. This initial contact is crucial for locking in flavors and starting the caramelization process. By taking the time to heat the pan correctly and using both butter and oil, you’ll create a base that enhances the natural flavors of the mushrooms and onions, resulting in a dish that’s both tender and packed with depth.

Cook Onions: Sauté onions until translucent, about 5 minutes, stirring occasionally
To begin the process of making sautéed mushrooms and onions, the first step is to focus on cooking the onions properly. Start by heating a large skillet over medium heat and adding a tablespoon of olive oil or butter. Allow the oil to heat for about 30 seconds, ensuring it coats the bottom of the skillet evenly. This initial heating is crucial as it prepares the pan to cook the onions without sticking or burning. Once the oil is hot, add the sliced onions to the skillet, making sure they are spread out in an even layer. This arrangement allows each piece of onion to cook uniformly.
As the onions start to sizzle, use a spatula or wooden spoon to stir them gently. The goal here is to sauté the onions until they become translucent, which typically takes about 5 minutes. Stirring occasionally is important to prevent the onions from sticking to the pan and to ensure they cook evenly. During this time, you’ll notice the onions softening and changing color from opaque white to a light, almost glass-like appearance. This transformation indicates that the onions are releasing their natural sugars and beginning to caramelize slightly, adding depth of flavor to the dish.
While cooking, keep a close eye on the onions and adjust the heat if necessary. Medium heat is ideal for sautéing onions, as it allows them to cook through without burning. If the onions start to brown too quickly, reduce the heat slightly and continue stirring. Conversely, if they seem to be cooking too slowly, you can increase the heat a notch, but be cautious to avoid scorching. The key is to maintain a steady temperature that encourages even cooking and gradual caramelization.
During the 5-minute cooking process, the onions will release moisture, which will help create a slightly steamy environment in the skillet. This moisture is natural and aids in the cooking process, but if the skillet becomes too wet, you can increase the heat slightly to evaporate the excess liquid. The onions are ready when they are tender, translucent, and slightly golden around the edges. At this stage, they should have a mild, sweet aroma, signaling that their flavor has developed beautifully.
Once the onions are translucent, it’s time to move on to the next step in the recipe, typically adding the mushrooms. However, ensure the onions are fully cooked before proceeding, as undercooked onions can have a sharp, raw taste that may overpower the dish. Properly sautéed onions provide a flavorful base for the mushrooms and enhance the overall taste of the sautéed mushroom and onion dish. This simple yet essential step sets the foundation for a delicious and well-balanced final product.

Add Mushrooms: Toss mushrooms in, cook until golden and moisture evaporates
Once your onions have softened and taken on a translucent quality, it’s time to add the mushrooms. Start by tossing the sliced mushrooms into the pan with the onions. Ensure the mushrooms are spread out in an even layer to allow for proper cooking. If the pan seems dry, add a small splash of olive oil or butter to prevent sticking. The mushrooms will release moisture as they cook, so avoid overcrowding the pan, as this can cause them to steam instead of sauté. Use a spatula to gently stir the mushrooms, combining them with the onions and coating them in the oil or butter.
As the mushrooms cook, you’ll notice they begin to shrink and release their natural juices. Continue to sauté them over medium heat, stirring occasionally to ensure even browning. The goal here is to achieve a golden-brown color on the mushrooms, which enhances their flavor and texture. This process typically takes about 5–7 minutes, depending on the heat and the type of mushrooms you’re using. Be patient and resist the urge to stir too frequently, as this can prevent the mushrooms from developing that desirable caramelization.
Keep an eye on the moisture level in the pan. Initially, the mushrooms will release water, creating a pool of liquid at the bottom of the pan. As cooking progresses, this moisture will gradually evaporate, leaving behind tender, golden mushrooms. Once the liquid has mostly evaporated, the mushrooms will start to sizzle again in the oil or butter. This is a sign that they’re nearing the perfect texture—soft, slightly crispy, and deeply flavorful.
If you notice the mushrooms browning too quickly or the pan becoming dry, reduce the heat slightly and add a touch more oil or butter. Conversely, if the mushrooms are releasing too much moisture and not browning, increase the heat to help the liquid evaporate faster. The key is to strike a balance between cooking off the excess moisture and allowing the mushrooms to develop a rich, golden color.
Once the mushrooms are golden and the moisture has evaporated, they’re ready to be seasoned and finished. At this stage, the mushrooms should be tender but still hold their shape, with a slightly crispy exterior. Give them a final stir to ensure they’re well combined with the onions, and proceed to the next steps of seasoning and serving. This stage is crucial for achieving the perfect sautéed mushrooms—golden, flavorful, and free of excess moisture.

Season & Serve: Add garlic, season with salt and pepper, serve hot as a side
Once your mushrooms and onions have developed a beautiful golden-brown color and softened to your liking, it's time to elevate the dish with the final touches. Add garlic to the pan, mincing 2-3 cloves and stirring them into the mixture. Garlic burns easily, so add it towards the end of cooking to preserve its aromatic flavor without bitterness. Sauté the garlic for about 1-2 minutes, just until it becomes fragrant and slightly softened, ensuring it blends seamlessly with the mushrooms and onions.
Next, season with salt and pepper to enhance the natural flavors of the ingredients. Start with a pinch of salt and a few grinds of black pepper, then taste and adjust as needed. Salt not only brings out the earthy richness of the mushrooms but also balances the sweetness of the caramelized onions. Pepper adds a subtle heat and depth, tying the dish together. Remember, it’s easier to add more seasoning than to correct an overly salted dish, so season gradually.
After seasoning, give the mixture a final stir to ensure the garlic, salt, and pepper are evenly distributed. The dish should now be fragrant, flavorful, and ready to serve. Serve hot as a side to complement your main course. This sautéed mushroom and onion mixture pairs beautifully with grilled meats, roasted vegetables, or even as a topping for steaks, burgers, or grain bowls. Its versatility makes it a go-to side for any meal.
For an extra touch, consider adding a sprinkle of fresh herbs like parsley or thyme just before serving. These herbs add a burst of freshness and color, elevating the dish visually and aromatically. Alternatively, a squeeze of lemon juice can brighten the flavors and add a tangy contrast to the savory richness of the mushrooms and onions.
Finally, transfer the sautéed mushrooms and onions to a serving dish while still hot to maintain their texture and warmth. This dish is best enjoyed immediately, as the flavors are most vibrant when freshly cooked. Whether as a simple side or a flavorful addition to other dishes, this seasoned and garlic-infused mixture is sure to impress with its depth and simplicity.
