Ingredients You’ll Need

Here’s everything you need to whip up this delicious beef and bell pepper stir-fry recipe, along with some handy substitution suggestions for flexibility:

• 1 lb flank steak, thinly sliced (or substitute sirloin or skirt steak)
• 2 tbsp cornstarch (helps achieve that crispy beef texture!)
• 2 tbsp oil (neutral oils like vegetable or canola work well)
• 1 red bell pepper, sliced (substitute yellow or green bell peppers for variety)
• 1 medium onion, sliced
• 2 cloves garlic, minced
• 1 tsp grated ginger (optional, but adds a nice zing)

For the Sauce:

• 1/4 cup soy sauce (use tamari for a gluten-free option)
• 2 tbsp hoisin sauce
• 1 tbsp brown sugar (adjust for sweetness to taste)

How to Make Crispy Beef and Bell Pepper Stir Fry

Follow these easy steps to create your crispy beef stir fry at home:

1. Prep the Beef

• Toss the thinly sliced beef with cornstarch in a small bowl. This coating ensures that irresistibly crispy texture when cooked.
• Heat oil in a large wok or skillet over medium-high heat. Add the beef in batches to avoid overcrowding and cook until crispy and browned. Remove from the pan and set aside.

2. Stir Fry the Vegetables

• Using the same pan, add a little more oil if needed. Toss in the garlic, onion, and bell pepper.
• Stir-fry for about 2–3 minutes until the veggies soften and start to char slightly. This enhances their sweetness while maintaining a bit of crunch.

3. Make the Sauce

• While veggies cook, whisk together the soy sauce, hoisin sauce, brown sugar, rice vinegar, sesame oil, and water in a bowl. Adjust the sweetness or tanginess to suit your taste.

4. Combine Everything

• Reduce the heat and pour the sauce into the pan with the veggies. Allow it to simmer for 1–2 minutes until it thickens slightly.
• Return the cooked beef to the pan and toss to coat everything in that glossy, sticky sauce.

5. Serve and Enjoy

• Serve hot over steamed jasmine rice or noodles. Garnish with green onions or sesame seeds for an extra pop of flavor.

Pro Tips for the Perfect Beef and Bell Pepper Stir Fry Recipe

• Slice Against the Grain: For tender beef, always slice against the grain.
• Preheat Your Pan: A hot wok or skillet is key to achieving that perfect sear.
• Don’t Overcrowd the Pan: Cook the beef in batches to keep it crispy.

How to Store and Reheat Leftovers

• Storage: Place leftovers in an airtight container and refrigerate for up to 3 days.
• Reheat: Reheat in a skillet until warmed through, adding a splash of water or soy sauce to refresh the sauce.
• Freezing: While freezing is not ideal for crispy beef, it can be frozen in a pinch. Thaw before reheating.

Common Mistakes and How to Avoid Them

1. Overcrowding the Pan

If the beef isn’t spaced out, it will steam instead of crisp. Cook in small batches.

2. Skipping the Cornstarch

This step is essential for crispy beef, so don’t omit it.

3. Overcooking the Veggies

Keep an eye on the peppers and onions. Aim for tender yet slightly crunchy for the best texture.
