How to Make Garlic Butter Mushrooms & Onions
Step 1: Prepare the Mushrooms
Start by brushing the mushrooms clean. If their stems look dried out, trim them off. Keeping them whole adds a nice presentation; however, if they’re large, feel free to cut them in half. This step ensures that every bite is tender and flavorful.
Step 2: Sauté the Mushrooms
In a large skillet over medium-high heat, add olive oil followed by the mushrooms. Cook and stir until they start to brown and caramelize—this should take about 3-5 minutes. Browning enhances their flavor and gives them that lovely golden color.
Step 3: Add Garlic and Onions
Once your mushrooms are beautifully golden, add 2 tablespoons of butter along with the minced onions and garlic. Cook until everything is lightly caramelized and softened—around 3-5 minutes. This step is crucial as it develops layers of flavor that make this dish irresistible!
Step 4: Enhance with Stock and Lemon
Pour in your choice of chicken stock or white grape juice along with lemon zest, lemon juice, and chili flakes. Allow this mixture to cook for another 2 minutes until the liquid reduces slightly. The acidity from the lemon brightens up all those rich flavors!
Step 5: Finish It Off
Finally, add the remaining butter and chopped parsley, cooking for an additional minute just until everything is combined beautifully. Season with salt and pepper to taste then serve warm! Enjoy this delicious medley as a side dish at your next meal!
