Servings: 4 | Prep Time: 10 minutes | Cook Time: 15 minutes | Total Time: 25 minutes

Ingredients

For the Stir Fry:

• 12 oz (340g) udon noodles (fresh or frozen; if dried, cook according to package first)
• 1 lb (450g) beef sirloin or flank steak, thinly sliced against the grain
• 1 tbsp vegetable oil
• 1 red bell pepper, thinly sliced
• 1 cup (100g) snap peas or broccoli florets
• 2 green onions, sliced (white and green parts separated)

For the Sauce:

• 3 tbsp (45ml) soy sauce
• 1 tbsp (15ml) gochujang (Korean chili paste) or sriracha
• 1 tbsp (15ml) sesame oil
• 1 tbsp (12g) brown sugar
• 1 tsp rice vinegar
• 2 garlic cloves, minced
• 1 tsp fresh ginger, grated

For Garnish (Optional):

• Fresh cilantro, chopped
• Sesame seeds

Instructions

1. Prep the Noodles: If using fresh or frozen udon, cook or rinse according to package instructions, then drain and set aside.
2. Cook the Beef: Heat vegetable oil in a large skillet or wok over high heat. Add the sliced beef in a single layer and cook for 2-3 minutes until browned. Remove to a plate.
3. Stir Fry Veggies: In the same skillet, add bell pepper, snap peas (or broccoli), and the white parts of the green onions. Stir-fry for 2-3 minutes until crisp-tender.
4. Make the Sauce: In a small bowl, whisk together soy sauce, gochujang, sesame oil, brown sugar, rice vinegar, garlic, and ginger until smooth.
5. Combine Everything: Return the beef to the skillet, add the udon noodles, and pour the sauce over top. Toss everything together for 2-3 minutes until the noodles are coated and the sauce thickens slightly.
6. Serve: Transfer to plates or bowls, sprinkle with green onion tops, cilantro, and sesame seeds, and dig in while it’s hot!
