Why You’ll Love This Beef and Bell Pepper Recipe
There are plenty of reasons to add this easy beef stir-fry to your weekly dinner rotation.
First, it’s incredibly flavorful. The tender beef absorbs the glossy sweet and tangy sauce, while the bell peppers add a fresh, slightly sweet crunch.
Second, it’s quick. Unlike slow-cooked beef recipes, thin strips of beef only need a few minutes in a hot skillet or wok.
And finally, it’s versatile. You can serve it over rice for a complete meal, add noodles for an easy stir-fry dinner, or customize it with your favorite vegetables.
What Makes This Recipe Special?
The secret is cooking the beef over high heat. This creates beautifully browned edges while keeping the inside tender. The sauce is added at the end so it can quickly reduce and coat every piece of beef and every colorful pepper strip.
For the best results, slice the beef thinly against the grain. This simple technique makes a big difference in tenderness.
Ingredients
For the Beef
- 1 ½ pounds beef sirloin, flank steak, or top sirloin
- 2 tablespoons cornstarch
- 1 tablespoon soy sauce
- 1 tablespoon vegetable oil
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
For the Colorful Bell Peppers
- 1 red bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- ½ medium yellow onion, sliced
- 2 cloves garlic, minced
- 1 teaspoon fresh ginger, grated
For the Sweet & Tangy Sauce
- ⅓ cup low-sodium soy sauce
- ¼ cup ketchup
- 3 tablespoons brown sugar
- 2 tablespoons rice vinegar
- 1 tablespoon honey
- 1 tablespoon oyster sauce
- 1 teaspoon sesame oil
- ½ teaspoon crushed red pepper flakes, optional
- ¼ cup water
- 1 teaspoon cornstarch
For Serving
- Steamed white rice
- Sliced green onions
- Sesame seeds
- Fresh cilantro, optional
Instructions
1. Slice the Beef
Place the beef on a cutting board and slice it into thin strips, approximately ¼-inch thick.
For particularly tender beef, identify the direction of the muscle fibers and slice against the grain. This shortens the muscle fibers and makes each bite easier to chew.
Pat the beef dry with paper towels before seasoning.
2. Season the Beef
Place the sliced beef in a bowl. Add soy sauce, cornstarch, black pepper, garlic powder, and vegetable oil.
Toss everything together until the beef is evenly coated.
Let the beef sit for about 10 minutes while you prepare the vegetables and sauce.
The cornstarch helps create lightly crisp, browned edges and also helps the sauce cling beautifully to the beef.
3. Prepare the Sweet and Tangy Sauce
In a small bowl, whisk together the soy sauce, ketchup, brown sugar, rice vinegar, honey, oyster sauce, sesame oil, water, and cornstarch.
Whisk until the cornstarch is completely dissolved.
The combination of brown sugar and honey provides sweetness, while rice vinegar adds the bright tanginess that makes this beef stir-fry so addictive.
If you prefer a spicier dish, add crushed red pepper flakes to taste.
4. Cook the Beef
Heat a large skillet, cast-iron pan, or wok over medium-high to high heat.
Add a small amount of oil and allow it to become hot.
Add the beef in a single layer. Avoid overcrowding the pan. If necessary, cook the beef in two batches.
Sear the beef for approximately 2–3 minutes per side, or until browned around the edges and cooked through.
Transfer the cooked beef to a clean plate.
Pro Tip
Don’t constantly stir the beef. Letting it sit against the hot pan for a short time creates those delicious caramelized edges that make restaurant-style stir-fry so good.
5. Stir-Fry the Vegetables
Add the sliced onion and bell peppers to the same skillet.
Cook for approximately 3–5 minutes, stirring frequently.
You want the peppers to become slightly tender while maintaining some of their natural crunch.
Add the minced garlic and fresh ginger during the final minute of cooking.
Stir continuously so the garlic doesn’t burn.
6. Add the Sauce
Give the prepared sauce another quick stir because the cornstarch may have settled at the bottom.
Pour the sauce into the skillet with the vegetables.
Bring it to a gentle simmer and cook for about 1–2 minutes.
The sauce will begin to thicken and become glossy.
7. Return the Beef to the Pan
Add the cooked beef back to the skillet.
Toss everything together until the beef and peppers are completely coated in the sweet and tangy sauce.
Cook for another 1–2 minutes, just until everything is hot and the sauce becomes thick and shiny.
Be careful not to overcook the beef.
8. Garnish and Serve
Remove the skillet from the heat.
Sprinkle with sliced green onions and sesame seeds. Add fresh cilantro if desired.
Serve immediately over a generous scoop of steamed white rice.
The combination of tender beef, crisp colorful peppers, and glossy sauce makes this an incredibly satisfying weeknight dinner.
What Kind of Beef Is Best?
For this Tender Beef and Colorful Bell Peppers recipe, choose a tender cut that cooks quickly.
Flank steak is one of the best choices because it has excellent beefy flavor and becomes tender when sliced thinly against the grain.
Sirloin is another excellent option. It’s relatively lean, flavorful, and easy to find at most American grocery stores.
Top sirloin also works beautifully and is a great choice if you want tender beef without using a more expensive steak.
The most important step is not necessarily the cut—it’s how you slice it. Always slice the beef thinly against the grain for the most tender results.
How to Make the Beef Extra Tender
There are a few simple tricks that can make this beef and bell pepper stir-fry especially tender and flavorful.
Slice Against the Grain
This is the most important technique. Cutting across the muscle fibers makes the beef easier to chew.
Don’t Overcook It
Thin beef strips cook extremely quickly. Once they’re browned and cooked through, remove them from the pan to keep the tender beef juicy.
Use High Heat
A hot skillet allows the beef to sear quickly instead of slowly steaming. This creates beautifully browned edges and adds extra flavor to the sweet and tangy beef.
Don’t Overcrowd the Pan
Too much beef in the skillet lowers the temperature and prevents proper browning. Cook the beef in batches if needed.
Use Cornstarch
A light coating of cornstarch helps protect the beef during cooking while creating beautifully browned edges and helping the sweet and tangy sauce cling to every piece.
What to Serve With Sweet and Tangy Beef
This colorful beef and bell pepper stir-fry is delicious with several easy side dishes.
Steamed White Rice
Steamed white rice is the classic choice. It absorbs the extra sweet and tangy sauce perfectly and turns this beef dinner into a satisfying complete meal.
Brown Rice
For a heartier option, serve the tender beef and colorful bell peppers over cooked brown rice. Its nutty flavor pairs especially well with the rich sauce.
Fried Rice
Turn dinner into a takeout-style meal by serving this sweet and tangy beef stir-fry alongside homemade fried rice.
Noodles
Rice noodles, lo mein noodles, or even spaghetti can be tossed with the beef and sauce for a satisfying noodle dinner.
Steamed Vegetables
Broccoli, snow peas, carrots, or green beans make excellent additions or side dishes. They also add extra color and texture to the meal.
Easy Recipe Variations
One of the best things about this beef and peppers recipe is how easy it is to customize.
Make It Spicy
Add red pepper flakes, sliced jalapeños, or a little sriracha to the sauce for a spicy version of this sweet and tangy beef.
Add Broccoli
Add small broccoli florets with the bell peppers for extra texture, color, and crunch.
Add Pineapple
For a more tropical sweet-and-sour flavor, add small chunks of pineapple near the end of cooking. Pineapple pairs wonderfully with the savory beef and glossy sauce.
Make It Extra Saucy
If you love plenty of sauce with your rice or noodles, increase the sauce ingredients by about 50%. The additional sweet and tangy sauce is perfect for spooning over steamed rice.
Add More Vegetables
Try mushrooms, snow peas, carrots, zucchini, or baby corn to create your own colorful beef stir-fry recipe.
Storage and Reheating
Store leftover Tender Beef and Colorful Bell Peppers in an airtight container in the refrigerator for up to 3–4 days.
To reheat, place the leftovers in a skillet over medium heat and cook until warmed through. Add a small splash of water if the sauce has become too thick.
You can also reheat individual portions in the microwave.
For the best texture, avoid repeatedly reheating the beef stir-fry, as the beef can become tougher.
Frequently Asked Questions
Can I use frozen bell peppers?
Yes. Fresh bell peppers provide the best texture, but frozen peppers can work when you’re short on time. Keep in mind that frozen peppers tend to be softer after cooking.
Can I make this recipe ahead of time?
Absolutely. You can slice the beef and vegetables and prepare the sweet and tangy sauce several hours ahead. Keep everything refrigerated separately until you’re ready to cook.
Is this recipe spicy?
Not necessarily. The basic beef and bell peppers recipe has a sweet and tangy flavor rather than a strong spicy kick. Red pepper flakes are optional, so you can easily adjust the heat for your family.
Can I use chicken instead of beef?
Yes. Thinly sliced chicken breast or boneless chicken thighs can be substituted for beef. Adjust the cooking time according to the size of the chicken pieces and make sure the chicken is fully cooked.
What rice goes best with beef stir-fry?
Steamed jasmine rice is an excellent choice because its fragrant, slightly sticky texture pairs beautifully with the glossy sweet and tangy sauce. Long-grain white rice is also delicious.
What is the best way to serve beef and bell peppers?
For an easy weeknight dinner, serve the Tender Beef and Colorful Bell Peppers over steamed jasmine rice and garnish with sliced green onions and sesame seeds. The rice soaks up the glossy sauce while the colorful peppers add freshness and crunch.
