Easy Pepper Steak with Bell Peppers & Onions is a colorful, satisfying dinner made with tender strips of beef, crisp-tender bell peppers, sweet onions, and a rich savory sauce. Every bite combines juicy steak with vegetables coated in a glossy garlic-soy sauce that tastes like something you would order from your favorite restaurant.
This recipe is especially useful for busy weeknights because most of the cooking happens quickly in one large skillet. The beef is seared over high heat to develop a flavorful browned exterior while staying tender inside, then the vegetables are cooked just long enough to soften without becoming mushy.
Serve this pepper steak over steamed white rice, brown rice, noodles, mashed potatoes, or even cauliflower rice. It is easy to customize, reheats well, and makes an excellent meal-prep option.
Why You’ll Love This Pepper Steak
Pepper steak is one of those recipes that delivers plenty of flavor without requiring complicated cooking techniques. Thinly sliced beef cooks in minutes, making it ideal when you want something hearty without spending hours in the kitchen.
The colorful combination of red, green, orange, or yellow bell peppers also makes the finished dish especially attractive. Onions add natural sweetness while garlic, soy sauce, Worcestershire sauce, and beef broth create a savory sauce that coats every ingredient.
Another advantage is how flexible the recipe is. You can increase the vegetables, adjust the heat level, change the type of steak, or make the sauce slightly sweeter depending on your family’s preferences.

How to Make Pepper Steak with Bell Peppers & Onions
1. Slice the Beef
Use a sharp knife to cut the steak across the grain into thin strips, approximately ¼-inch thick.
Cutting against the grain shortens the muscle fibers and helps produce much more tender pieces of beef. If the steak is difficult to slice, place it in the freezer for about 20 minutes first. Slightly firm beef is much easier to cut into evenly sized strips.
2. Season the Steak
Place the sliced beef in a bowl. Add 1 tablespoon soy sauce, cornstarch, black pepper, and garlic powder.
Toss everything together until each piece of beef is lightly coated. Allow the steak to rest for approximately 10–15 minutes while you prepare the vegetables and sauce.
The cornstarch creates a light coating around the meat that helps retain moisture while also encouraging browning.
3. Prepare the Sauce
In a small bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, tomato paste, sesame oil, black pepper, and optional red pepper flakes.
In a separate small cup, combine 1 tablespoon cornstarch with 2 tablespoons cold water to create a slurry. Set both mixtures aside.
Adding the slurry near the end of cooking allows you to control the thickness of the sauce.
4. Sear the Steak
Heat a large skillet or wok over medium-high to high heat. Add approximately 1 tablespoon of oil.
Once the skillet is very hot, arrange half of the steak in a single layer. Cook for approximately 1–2 minutes without moving it, then turn and cook for another minute.
Transfer the browned steak to a plate and repeat with the remaining beef.
Avoid overcrowding the skillet. Adding too much meat at once lowers the temperature and causes the beef to steam rather than sear.
The steak does not need to be completely cooked at this stage because it will finish cooking in the sauce.
5. Cook the Bell Peppers and Onions
Add the remaining tablespoon of oil to the same skillet.
Add the green, red, and orange bell peppers along with the yellow and red onions. Cook over medium-high heat for approximately 4–5 minutes, tossing occasionally.
You want the vegetables slightly tender while still retaining a little crunch.
Add the minced garlic and cook for another 30 seconds, stirring constantly so it does not burn.
6. Add the Sauce
Pour the prepared sauce into the skillet with the vegetables.
Stir while scraping any browned bits from the bottom of the pan. These caramelized pieces contain plenty of flavor and will make the sauce even richer.
Bring the sauce to a gentle simmer.
7. Return the Beef to the Skillet
Add the cooked steak and any juices collected on the plate back to the skillet.
Toss everything together so the beef and vegetables become evenly coated.
Simmer for approximately 2 minutes.
Stir the cornstarch slurry again before gradually pouring it into the skillet. Continue stirring for approximately 1–2 minutes until the sauce becomes glossy and slightly thickened.
Remove the skillet from the heat as soon as the beef is cooked through and tender.
What to Serve With Pepper Steak
The classic pairing for pepper steak is fluffy steamed white rice because the rice absorbs the rich sauce beautifully.
You can also serve it with:
- Jasmine or basmati rice
- Brown rice
- Egg noodles
- Garlic noodles
- Mashed potatoes
- Roasted potatoes
- Cauliflower rice
- Steamed broccoli
- Green beans
- Simple cucumber salad
For an especially satisfying dinner, spoon plenty of the savory pepper steak sauce over the rice before adding the beef and vegetables.
Tips for the Best Pepper Steak
Slice against the grain. This is one of the most important steps for tender steak.
Use high heat. A properly heated skillet gives the beef a beautiful seared exterior instead of allowing it to steam.
Cook in batches. Leaving space between the pieces of steak helps achieve better browning.
Don’t overcook the vegetables. Bell peppers should remain colorful and slightly crisp.
Choose the right beef. Sirloin, flank steak, skirt steak, or ribeye all work well.
Adjust the sauce consistency. Add a splash of beef broth if your sauce becomes too thick. Add a little more cornstarch slurry if you prefer it thicker.
Easy Recipe Variations
Spicy Pepper Steak
Add ½ teaspoon crushed red pepper flakes, sliced jalapeño, or a teaspoon of chili garlic sauce.
Mushroom Pepper Steak
Add 8 ounces of sliced mushrooms along with the onions. Mushrooms absorb the sauce beautifully and make the meal even heartier.
Extra-Vegetable Pepper Steak
Add broccoli florets, zucchini, snap peas, carrots, or baby corn.
Sweeter Pepper Steak
Increase the brown sugar to 2 tablespoons for a slightly sweeter restaurant-style sauce.
Storage and Reheating
Allow leftovers to cool before transferring them to an airtight container.
Pepper steak can be refrigerated for 3–4 days.
Reheat it gently in a skillet over medium-low heat with 1–2 tablespoons of beef broth or water. Stir occasionally until completely heated through.
You can also microwave individual portions in 30-second intervals, stirring between intervals.
Avoid overheating the beef because prolonged cooking can make the steak tougher.
Frequently Asked Questions
What steak is best for pepper steak?
Sirloin and flank steak are excellent choices because they cook quickly and absorb the sauce well. Ribeye can also be used for an especially rich and tender result.
Why is my pepper steak tough?
The beef may have been sliced with the grain, cut too thick, or cooked too long. Thinly slicing against the grain and cooking quickly over high heat usually produces the best texture.
Can I prepare this recipe ahead of time?
Yes. Slice the steak and vegetables and prepare the sauce up to one day ahead. Store everything separately in the refrigerator, then cook just before serving.
Can I use frozen bell peppers?
Fresh peppers provide the best texture, but frozen sliced peppers can work. Cook them directly from frozen and expect a slightly softer finished texture.
Can I make pepper steak without cornstarch?
Yes, although the sauce will be thinner. Arrowroot powder can also be substituted for cornstarch.
