Instructions

Cook the Onions

1. Heat olive oil in a skillet or sauté pan over medium-high heat.
2. Add the sliced onions and cook, stirring often, for 2 minutes until slightly softened.

Sauté the Mushrooms

1. Add the sliced mushrooms, season with salt and pepper, and cook for 3–4 minutes, stirring occasionally. The salt will help release the mushroom juices.
2. Continue cooking until most of the liquid evaporates and the mushrooms are tender.

Add Garlic and Finish

1. Reduce heat to low, melt the butter, and add the garlic. Cook for 30 seconds until fragrant.
2. Stir in soy sauce and add a splash of white wine (or stock) to deglaze the pan, scraping any browned bits from the bottom with a wooden spoon.
3. Add chopped fresh thyme and cook for an additional 30 seconds. Remove from heat.
