Ingredients

Instructions

  1. Step 1: Slice 8 oz flank steak against the grain into 1/4-inch thick strips; season with 1/4 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Heat 2 tbsp avocado oil in a large skillet over high heat until shimmering. Add steak in a single layer and sear undisturbed for 2 minutes until golden brown, then flip and sear 1 minute more until medium-rare — do not overcrowd the pan.
  3. Step 3: Remove steak and set aside. Add 1 cup broccoli florets to the skillet and stir-fry for 3 minutes until bright green and slightly crisp-edged.
  4. Step 4: Mince 3 garlic cloves and add to skillet; cook for 30 seconds until fragrant but not browned. Pour in 1/4 cup heavy cream and 1 tbsp soy sauce, stirring constantly until sauce thickens and coats the back of a spoon.
  5. Step 5: Return steak to skillet, toss to coat in sauce, and heat through for 1 minute. Stir in 1 tsp sesame oil and serve immediately.
