Ingredients
- 12 oz beef sirloin
- 8 oz cremini mushrooms
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 1 finely diced shallot
- 3 cloves minced garlic
- 1/2 cup heavy cream
- 1 tsp chopped fresh thyme
- 1/4 tsp sea salt
- 1/8 tsp black pepper
Instructions
- Step 1: Pat beef sirloin dry with paper towels, then cut into 1/2-inch strips. Season with 1/4 tsp sea salt and 1/8 tsp black pepper.
- Step 2: Heat olive oil in a large skillet over medium-high heat until shimmering. Add beef strips in a single layer and sear undisturbed for 2 minutes until browned, then flip and cook 2 minutes more until medium-rare; transfer to a plate.
- Step 3: Reduce heat to medium, add 1 tbsp butter and shallot, cooking 2 minutes until softened. Stir in garlic and cook 30 seconds until fragrant without browning.
- Step 4: Add mushrooms and cook 5 minutes until golden and liquid evaporates. Return beef to skillet, pour in heavy cream, and stir in thyme. Simmer 3 minutes until sauce thickens and coats the back of a spoon.
- Step 5: Remove from heat, add remaining 2 tbsp butter, and swirl until melted. Taste and adjust seasoning with extra salt if needed.
