Ingredients

- 1 large onion, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter

- 2 cloves garlic, minced
- 1 tablespoon fresh parsley, chopped
Equipment Needed

- Wooden spoon
- Measuring spoons
- Cutting board
- Knife
Instructions

Step 1: Prepare Your Ingredients
Start by laying out all your ingredients. Slice the mushrooms uniformly to ensure even cooking. For the onions, go for thin slices to help them caramelize quickly. Mince the garlic finely. Set everything in easy reach near your stove. Preparing ahead acts as your stress-buster when juggling meal prep around family duties.
Step 2: Heat the Skillet
Place your large skillet over medium-high heat. Add the olive oil and butter; the butter should melt around the same time the oil shimmers. Combining butter and oil gives you both a high smoke point and a rich, buttery flavor that elevates the mushrooms and onions beautifully.
Step 3: Start Sautéing the Onions
Add the sliced onions to the skillet first, allowing them to cook for about 5 minutes. Stir them occasionally using a wooden spoon. Aim for a light brown color as the edges caramelize. Caramelizing now sets the foundation for richer flavors.
Step 4: Add Mushrooms and Garlic
Toss the mushrooms into the skillet and stir to mix them with the onions. Let these cook together for another 5 minutes. When the mushrooms release their moisture, it’s time to add the garlic. Stir, ensuring the garlic does not burn, which would turn its taste bitter.
Step 5: Season and Garnish
Sprinkle in the salt and pepper, continuing to stir occasionally so they distribute evenly. Just before serving, toss in a tablespoon of chopped fresh parsley. Keeping herbs ready in advance helps you effortlessly add a dash of color and fresh aroma to the dish.
Tips and Tricks
Chop all your ingredients beforehand; it saves you from unnecessary hurry once the cooking starts. Use a non-stick skillet to prevent sticking and make cleanup easier. If you feel the dish is getting too dry at any point, a sprinkle of water can revitalize it without adding fat. To enhance the taste, consider seasoning with soy sauce instead of salt for an umami kick.
Recipe Variations
- Add Bell Peppers: Include sliced bell peppers for extra crunch and color.
- Balsamic Vinegar Drizzle: Add a tablespoon of balsamic vinegar in the final minute of cooking for extra depth.
- Herb Swap: Use thyme or rosemary instead of parsley for different herbal notes.
- Creamy Mushrooms: Stir in a quarter cup of heavy cream for a rich finish.
