How to Make Garlic Butter Mushrooms & Onions
Step 1: Prepare the Mushrooms
Start by brushing the mushrooms clean. Trimming the bottoms of their stems ensures they are fresh and ready to soak up all those delicious flavors. Keep them whole for a beautiful presentation; if they’re large, feel free to cut them in half.
Step 2: Sauté the Mushrooms
Heat a large skillet over medium-high heat and add olive oil. Once hot, add the mushrooms. Allow them to cook undisturbed until they begin to brown and caramelize—this depth of flavor is key! Stir occasionally for about 3-5 minutes.
Step 3: Add Aromatics
Next, introduce 2 tablespoons of butter into the skillet. As it melts, add your minced onions and chopped garlic. Cooking these until lightly caramelized softens their texture and enhances their sweetness, which balances beautifully with the mushrooms.
Step 4: Add Flavorful Liquid
Pour in your choice of chicken stock or white grape juice along with lemon zest, lemon juice, and chili flakes. This step is crucial as it adds moisture and tanginess. Allow everything to cook together for about 2 minutes until the liquid reduces slightly.
Step 5: Finish Up
Finally, stir in the remaining 2 tablespoons of butter along with the chopped parsley. This final touch not only adds richness but also brightens up your dish with fresh herb flavor. Season with salt and pepper to taste before serving warm.
Enjoy creating this delightful Garlic Butter Mushrooms & Onions side dish—your friends and family will be asking for seconds!
