Ingredients
Scale
- 1 ½ tablespoons unsalted butter: Butter is the backbone of flavor in this recipe, providing a rich, creamy base that beautifully complements the earthy mushrooms and sweet onions. Unsalted butter is preferred as it allows you to control the overall saltiness of the dish, ensuring a balanced flavor profile. The fat in butter also aids in browning the mushrooms and onions, contributing to a deeper, more complex taste through the Maillard reaction. For a richer, more pronounced buttery flavor, you can opt for European-style butter, which has a higher fat content. If you are dairy-free, you can substitute with a high-quality vegan butter alternative, ensuring it’s one that browns well for optimal flavor development.
- 2 tablespoons olive oil: Olive oil joins forces with butter to create the perfect cooking medium. While butter provides flavor, olive oil has a higher smoke point, preventing the butter from burning as you sauté the vegetables over medium heat. The combination of butter and olive oil also contributes to a balanced fat profile and a delightful texture in the final dish. Extra virgin olive oil, with its robust flavor, is a great choice, but a lighter olive oil or even avocado oil will also work well, especially if you prefer a more neutral oil flavor. Using a good quality olive oil will enhance the overall taste and aroma of your sautéed mushrooms and onions.
- 1 pound cremini mushrooms, sliced: Cremini mushrooms, also known as baby bellas, are the star of this recipe. They offer a deeper, more earthy flavor than white button mushrooms, making them ideal for sautéing. Their firm texture also holds up well to the cooking process, preventing them from becoming mushy. Slicing the mushrooms allows for even cooking and maximizes surface area for browning and flavor absorption. When selecting cremini mushrooms, look for firm, unblemished caps with a fresh, earthy aroma. Avoid mushrooms that appear slimy or have a strong, ammonia-like smell. If you can’t find cremini mushrooms, you can substitute with other varieties like white button mushrooms, portobello mushrooms (sliced), or even a mix of wild mushrooms for a more complex flavor profile. Remember to clean your mushrooms gently with a dry brush or paper towel to remove any dirt; avoid washing them as they absorb water and can become soggy.
- ½ teaspoon salt, divided in half: Salt is a critical seasoning that enhances the natural flavors of both the mushrooms and onions. Dividing the salt and adding it in stages throughout the cooking process is key to drawing out moisture from the mushrooms and onions, facilitating browning, and ensuring even seasoning. The initial ¼ teaspoon added with the mushrooms helps to release their moisture, allowing them to sauté and brown rather than steam. The second ¼ teaspoon added with the onions further seasons the dish and balances the sweetness of the onions. You can use kosher salt, sea salt, or table salt, adjusting the amount to your personal preference. Taste and adjust seasoning at the end of cooking to ensure the dish is perfectly seasoned to your liking.
- 1 sweet onion, sliced: Sweet onions, like Vidalia or Walla Walla onions, are preferred in this recipe for their mild, sweet flavor that caramelizes beautifully as they sauté. Their sweetness provides a lovely contrast to the earthy mushrooms and savory Worcestershire sauce. Slicing the onion allows it to cook evenly alongside the mushrooms and ensures a tender texture. If you don’t have sweet onions, you can use yellow onions, although they have a slightly sharper flavor. In this case, you might consider cooking them a little longer to allow their natural sugars to caramelize and mellow their flavor. Red onions can also be used for a slightly more pungent flavor, but their color might bleed slightly into the mushrooms. Ensure you slice the onions relatively thinly and uniformly for even cooking.
- 1 lemon, zested and juiced: Lemon zest and juice bring a bright, acidic counterpoint to the richness of the mushrooms and onions, adding a layer of freshness and complexity to the dish. Lemon zest, the grated outer rind of the lemon, provides aromatic oils that infuse the dish with a vibrant citrusy fragrance. Lemon juice, the liquid extracted from the lemon, adds acidity that balances the savory flavors and brightens the overall taste. Use a microplane or fine grater to zest the lemon, ensuring you only grate the yellow part and avoid the bitter white pith underneath. Freshly squeezed lemon juice is always preferred over bottled juice for its superior flavor and brightness.
- 2 cloves garlic, minced: Garlic is an essential aromatic that adds depth and pungency to the sautéed mushrooms and onions. Its savory, slightly spicy flavor complements both the mushrooms and onions beautifully, creating a more complex and flavorful dish. Minced garlic releases its aromatic oils and flavors quickly into the hot butter and oil, infusing the entire dish. Fresh garlic cloves are always preferred for their superior flavor and aroma. If you don’t have fresh garlic, you can use garlic powder as a substitute, but the flavor will be less intense and nuanced. Adjust the amount of garlic to your preference; some may prefer a more subtle garlic flavor, while others might enjoy a more pronounced garlic punch.
- ¼ cup low sodium vegetable broth: Vegetable broth adds moisture to the pan as the mushrooms and onions cook, preventing them from drying out and helping to deglaze the skillet, lifting up any flavorful browned bits from the bottom. Low sodium broth is recommended to control the overall saltiness of the dish, allowing you to adjust the seasoning to your liking. Vegetable broth also contributes a subtle savory flavor that complements the other ingredients. If you don’t have vegetable broth, you can substitute with chicken broth or even dry white wine for a different flavor profile. Water can also be used in a pinch, but broth or wine will add more depth of flavor.
- 1 tablespoon Worcestershire sauce: Worcestershire sauce is the secret ingredient that elevates these sautéed mushrooms and onions to another level. It provides a rich, umami-packed depth of flavor that is complex and savory, adding a layer of deliciousness that you can’t quite put your finger on. Worcestershire sauce is made from a blend of vinegar, molasses, tamarind, anchovies, and other seasonings, resulting in a uniquely savory and tangy flavor. It enhances the earthiness of the mushrooms and complements the sweetness of the onions, creating a well-rounded and intensely flavorful dish. If you are vegetarian or vegan, ensure your Worcestershire sauce is vegan, as traditional versions contain anchovies. There are many vegan Worcestershire sauce options available that offer a similar depth of flavor.
Instructions
- Heat butter and oil in a large skillet: Begin by selecting a large skillet, preferably cast iron or stainless steel, as these materials distribute heat evenly and promote good browning. Place the skillet over medium heat on your stovetop. Add 1 ½ tablespoons of unsalted butter and 2 tablespoons of olive oil to the skillet. Allow the butter to melt completely and shimmer in the oil. The combination of butter and oil creates a flavorful cooking medium that prevents burning and facilitates even browning of the mushrooms and onions. Ensure the heat is medium; if it’s too high, the butter can burn, and if it’s too low, the vegetables will steam instead of sautéing.
- Add mushrooms and salt: Once the butter is melted and hot, add 1 pound of sliced cremini mushrooms to the skillet. Immediately sprinkle ¼ teaspoon of salt evenly over the mushrooms. The salt will draw out moisture from the mushrooms, which is crucial for the sautéing process. Stir the mushrooms to coat them evenly with the butter and oil mixture. It’s important not to overcrowd the skillet at this stage; if necessary, sauté the mushrooms in batches to ensure they brown properly. Overcrowding will lead to steaming instead of sautéing.
- Cook mushrooms for 10 minutes: Allow the mushrooms to cook, stirring occasionally, for approximately 10 minutes. Initially, the mushrooms will release a significant amount of liquid. Continue to cook them, stirring occasionally, allowing this liquid to evaporate. As the liquid evaporates, the mushrooms will begin to brown and caramelize, developing a richer, more intense flavor. This browning process, known as the Maillard reaction, is key to achieving the desired umami flavor in sautéed mushrooms. Don’t be tempted to increase the heat to speed up the process; medium heat is ideal for even browning and preventing burning.
- Add onions and salt: After the mushrooms have cooked for 10 minutes and started to brown, add 1 sliced sweet onion to the skillet. Sprinkle another ¼ teaspoon of salt over the onions. The salt will help to draw out moisture from the onions as well and season them evenly. Stir the onions to combine them with the mushrooms and the cooking juices in the skillet.
- Cook onions for 8 minutes: Continue to cook the mushrooms and onions together, stirring occasionally, for another 8 minutes. During this time, the onions will soften and become translucent. As they cook further, they will begin to caramelize and develop a sweet, savory flavor that complements the earthy mushrooms. Keep stirring occasionally to ensure even cooking and prevent sticking. The goal is to cook the onions until they are tender and slightly browned, but not burnt.
- Add lemon zest, juice, garlic, broth, and Worcestershire sauce: After the onions have cooked for 8 minutes and are softened, it’s time to add the flavor enhancers. Add 1 teaspoon of lemon zest, 1 tablespoon of lemon juice, 2 cloves of minced garlic, ¼ cup of low sodium vegetable broth, and 1 tablespoon of Worcestershire sauce to the skillet. Stir everything together well to combine all the ingredients and ensure the garlic is evenly distributed. The lemon zest and juice will add brightness and acidity, the garlic will contribute its pungent aroma, the vegetable broth will add moisture and help deglaze the pan, and the Worcestershire sauce will provide a deep umami flavor.
- Cook until liquid evaporates: Continue to cook the mixture for another 2 to 4 minutes, or until most of the liquid has evaporated. Stir occasionally to prevent sticking and ensure even cooking. As the liquid reduces, the flavors will concentrate, creating a more intense and flavorful sauce that coats the mushrooms and onions. The desired consistency is when most of the liquid has evaporated, leaving behind a slightly glossy and flavorful coating on the vegetables. Be careful not to overcook and dry out the mushrooms and onions completely.
- Serve immediately: Once the liquid has mostly evaporated and the mushrooms and onions are beautifully coated in the flavorful sauce, the dish is ready to serve. Serve immediately while hot to enjoy the best texture and flavor. You can garnish with some fresh chopped green onions or parsley for a touch of freshness and visual appeal, if desired. These sautéed mushrooms and onions are delicious served as a side dish or as a topping for a variety of dishes.
