How to Make Garlic Butter Mushrooms & Onions
Step 1: Prepare the Mushrooms
Brush the mushrooms clean and trim any dried-out stems. Keeping them whole adds to their rustic charm, but if they’re large, feel free to cut them in half. This step ensures they cook evenly and absorb all those yummy flavors.
Step 2: Sauté the Mushrooms
Heat a large skillet over medium-high heat. Add olive oil, then toss in the mushrooms. Cook and stir until they start to brown and caramelize—this should take about 3–5 minutes. Browning gives them that lovely deep flavor we crave!
Step 3: Add Garlic and Onions
Now it’s time to add 2 tablespoons of butter. Let it melt a bit before adding minced onions and garlic. Cook until everything is lightly caramelized and softened—about 3–5 minutes. This step enhances sweetness from the onions while infusing flavor from the garlic.
Step 4: Pour in Stock and Seasonings
Next, pour in your choice of chicken stock or white grape juice along with lemon zest, lemon juice, and chili flakes. Let this simmer for about two minutes until the liquid reduces slightly. This creates a luscious sauce that will coat your mushrooms beautifully.
Step 5: Finish Up
Add the remaining 2 tablespoons of butter along with chopped parsley—cook for an additional minute. Season generously with salt and pepper to taste. Serve warm as a delightful side dish that everyone will adore!
Enjoy making these Garlic Butter Mushrooms & Onions! They truly are a comfort food classic that adds warmth to any meal.
Pro Tips for Making Garlic Butter Mushrooms & Onions
Making Garlic Butter Mushrooms & Onions is as easy as pie, and with these pro tips, you’ll elevate your dish to a whole new level!
-
Use fresh mushrooms: Fresh mushrooms have a better flavor and texture than canned ones. They’ll absorb the garlic butter beautifully and give your dish that irresistible umami taste.
-
Don’t overcrowd the pan: Cooking in batches prevents steaming. If you add too many mushrooms at once, they won’t brown properly. Give them space to caramelize and develop that lovely golden color.
-
Experiment with herbs: Adding fresh herbs like thyme or rosemary can enhance the flavor profile. Herbs infuse the dish with aromatic notes that complement the earthy mushrooms and sweet onions.
-
Adjust seasoning to your taste: Feel free to tweak the salt, pepper, and chili flakes based on your preference. This allows you to customize the dish to suit your palate perfectly.
-
Serve immediately for best results: Garlic Butter Mushrooms & Onions are best enjoyed warm right off the stove. Their flavors are freshest when served straight away!
