Ingredients

Instructions

  1. 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.
  2. 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.
  3. Step 3: Stir in heavy cream, capers, Dijon mustard, thyme, and a pinch each of salt and pepper. Simmer gently for 3 minutes until sauce thickens slightly.
  4. 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.
  5. Step 5: Meanwhile, heat spiralized zucchini noodles in a separate skillet with a drizzle of avocado oil over medium heat for 2-3 minutes until tender but still firm.
