When a busy weeknight calls for a quick, flavorful dinner, a Beef and Bell Pepper Stir-Fry checks all the boxes: it’s fast, nutritious, and delightfully savory. Combining tender slices of beef with the fresh crispness of colorful bell peppers, this dish offers a harmonious blend of textures and tastes that are better than many takeout options — and it’s easy to whip up at home.
Why Choose Beef and Bell Pepper Stir-Fry?
This dish is a classic in Asian-inspired kitchens, beloved for its simplicity and versatility. The combination of protein-rich beef and vitamin-packed bell peppers creates a balanced meal, especially when paired with steamed rice or noodles. Plus, stir-frying retains the bright flavors and nutrients of the vegetables, delivering a vibrant plate every time.

Ingredients Overview
Beef Selection:
The best cuts for stir-fry are those that become tender and flavorful when sliced thinly. Flank steak and sirloin are top choices due to their rich taste and moderate tenderness. For the most tender experience:
- Partially freeze the steak for 20-30 minutes to firm it up for thinner, more precise slicing.
- Cut across the grain at a 45-degree angle to shorten muscle fibers, ensuring each bite is tender, not chewy.
- Optionally pound the steak lightly to further tenderize.
Bell Peppers:
Use a medley of colors for visual appeal and flavor variety:
- Red, orange, and yellow peppers bring sweetness.
- Green peppers add a slight tang.
You can also add onions or tomatoes for extra layers of flavor.
Key Flavorings and Sauce:
The hallmark of this stir-fry is a savory, slightly sweet sauce made from:
- Soy sauce (regular or low sodium)
- Garlic and ginger for that aromatic punch
- Sugar to balance the saltiness
- Cornstarch dissolved in water to thicken the sauce
Optional additions include sesame oil, Worcestershire sauce, or even a dash of teriyaki sauce for a twist.
Step-by-Step Cooking Method
1. Prepare the Vegetables and Beef
- Slice bell peppers into strips (~1/4 inch wide).
- Thinly slice the beef after seasoning it with salt and pepper (and optionally pounding).
2. Cook the Bell Peppers and Aromatics
- Heat oil in a large skillet or wok over medium-high heat.
- Sauté bell peppers for 3-4 minutes until slightly tender but still crisp.
- Remove and set aside.
3. Brown the Beef
- Add a bit more oil if needed.
- Increase heat to high, then add the beef in a single layer.
- Let it sear without stirring until lightly browned, about 5-6 minutes.
- Toss in minced garlic and ginger, cooking for an additional 30 seconds to release their fragrance.
4. Combine and Simmer in Sauce
- Return the bell peppers to the pan.
- Whisk together the sauce ingredients: soy sauce, sugar, cornstarch slurry (cornstarch mixed with water).
- Pour the sauce over the beef and vegetables.
- Simmer for 2-3 minutes, stirring occasionally, until the sauce thickens and coats everything beautifully.
Serving Suggestions
Serve your beef and bell pepper stir-fry over fluffy steamed rice or enjoy it as is for a low-carb meal. For a complete dinner, add a side of steamed broccoli or a simple Asian cucumber salad. Leftovers also reheat well, making this dish ideal for meal prep.

Pro Tips for Perfect Stir-Fry Every Time
- Don’t overcrowd the pan: Cook the beef in batches if necessary to avoid steaming instead of searing.
- Keep veggies crisp: Remove them promptly when just tender to retain texture.
- Sauce consistency: Adjust thickness by varying cornstarch and water quantities.
- Experiment with vegetables: Snow peas, baby corn, broccoli, or sliced onions complement the dish beautifully.
- Marinate tougher cuts: Skirt steak benefits from a marinade with acidic ingredients like lemon juice or soy sauce for extra tenderness.
