Ingredients
- 1 lb (450g) flank steak
- 2 tbsp avocado oil
- 1 medium, finely diced yellow onion
- 2 cloves, minced garlic
- 8 oz (225g), sliced cremini mushrooms
- 1 cup (240ml) heavy cream
- 2 tbsp, drained capers
- 1 tbsp Dijon mustard
- 1 tsp dried thyme
- 1/4 cup, chopped fresh parsley
- 2 medium, spiralized zucchini
Instructions
- Step 1: Heat 1 tbsp avocado oil in a large skillet over medium-high heat until shimmering. Add beef strips and sear for 2-3 minutes per side until browned; remove and set aside.
- Step 2: Add remaining 1 tbsp avocado oil to the skillet. Sauté diced onion for 3-4 minutes until translucent, then add minced garlic and sliced mushrooms, cooking for 5-6 minutes until mushrooms are golden.

- Step 4: Return beef to skillet and stir to coat. Cook for 2-3 minutes until heated through and sauce coats the back of a spoon.
