How to Make Garlic Butter Mushrooms & Onions
Step 1: Prepare the Mushrooms
Start by brushing the mushrooms clean. Trim any dried-out ends from their stems, keeping them whole if they’re small. If they’re larger, cut them in half so they cook evenly. This step ensures your mushrooms are clean and ready to absorb all that delicious flavor!
Step 2: Sauté the Mushrooms
Heat a large skillet over medium-high heat and add olive oil. Once hot, toss in the mushrooms. Stir them frequently until they start to brown and caramelize—about 3-5 minutes. Cooking them until golden enhances their natural flavors and gives them that lovely texture we all crave.
Step 3: Add Garlic and Onions
Now it’s time to add 2 tablespoons of butter! Let it melt slightly before adding in the minced onions and chopped garlic. Cook everything together until lightly caramelized—about another 3-5 minutes. The garlic will fill your kitchen with an amazing aroma while softening the onions brings out their sweetness.
Step 4: Create That Flavorful Sauce
Pour in your choice of chicken stock or white grape juice along with lemon zest, lemon juice, and chili flakes. Let everything simmer for about 2 minutes until the liquid reduces slightly. This step adds depth to your dish—trust me; it’s worth it!
Step 5: Finish Off with Butter and Parsley
Finally, stir in the remaining 2 tablespoons of butter along with chopped parsley. Cook for an additional minute until everything is well combined and buttery rich. Don’t forget to season with salt and pepper before serving warm! This final touch enhances all those wonderful flavors we’ve built throughout cooking.
And there you have it! A delightful Garlic Butter Mushrooms & Onions dish ready to impress at any table!
