Ingredients (Serves 4)

400g button or cremini mushrooms, sliced
1 large onion (150g), thinly sliced
3 tbsp (45g) unsalted butter
1 tbsp (15g) olive oil
4 cloves garlic, minced
80ml dry white wine (such as Sauvignon Blanc or Chardonnay)
1 tsp (3g) salt (or to taste)
1/2 tsp (2g) black pepper
1/2 tsp (2g) red pepper flakes (optional, for heat)
1/2 tsp (2g) thyme (dried or fresh)
1 tbsp (15g) fresh parsley, chopped
1 tbsp (15g) lemon juice (optional, for brightness)

Step-by-Step Instructions

Step 1: Prep the Ingredients

Clean the mushrooms by wiping them with a damp paper towel (avoid rinsing to prevent sogginess). Slice them evenly.
Thinly slice the onion and mince the garlic.

Step 2: Sauté the Onions

Heat 1 tbsp butter and 1 tbsp olive oil in a large skillet over medium heat.
Add the sliced onions and cook for 5-7 minutes, stirring occasionally, until they start to caramelize.

Step 3: Add the Mushrooms & Garlic

Increase the heat to medium-high and add the mushrooms. Cook for 5 minutes, stirring occasionally, until they start to brown.
Stir in the garlic, salt, black pepper, red pepper flakes, and thyme. Sauté for 1-2 minutes until fragrant.

Step 4: Deglaze with White Wine

Pour in the white wine, stirring to scrape up any browned bits from the pan.
Allow the wine to simmer for 3-4 minutes until it reduces by half and the mushrooms absorb the flavor.

Step 5: Finish with Butter & Herbs

Stir in the remaining 2 tbsp of butter and let it melt, coating everything in a rich, glossy sauce.
Remove from heat and stir in fresh parsley and lemon juice for brightness.

Step 6: Serve & Enjoy

Serve immediately as a side dish with steak, grilled chicken, pasta, or crusty bread.
Optionally, top with grated Parmesan cheese for extra richness.
