Instructions

  1. Step 1: Heat 1 tbsp sesame oil in a large skillet over medium-high heat until shimmering. Add 12 oz thinly sliced beef sirloin, 1/2 tsp salt, and 1/4 tsp black pepper. Stir-fry for 3-4 minutes until browned but still tender, then remove beef from skillet.
  2. Step 2: In the same skillet, add remaining 1 tbsp sesame oil, 3 minced garlic cloves, 1 tsp freshly grated ginger, and 1/4 tsp red pepper flakes. Sauté for 30 seconds until fragrant.
  3. Step 3: Add 3 spiralized medium zucchinis (zoodles) and 3 tbsp soy sauce, tossing gently. Cook for 2-3 minutes until zoodles are slightly softened but still crisp.
  4. Step 4: Return beef to the skillet and toss everything together for 1 minute to combine flavors and heat through.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds before serving.

Can I substitute ingredients in Zucchini Noodle Stir-Fry with Garlic Sesame Beef?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Zucchini Noodle Stir-Fry with Garlic Sesame Beef for a different number of people?
