Ingredients You Need

Here is everything you need for this spicy chicken stir fry with bell peppers.

Chicken

1.5 pounds boneless skinless chicken breast or thighs, thinly sliced
- Thighs give a juicier result and forgive overcooking.
- Breast works great if you slice it thin across the grain.

Bell peppers and aromatics

3 bell peppers, mixed colors, sliced into strips
1 medium yellow or red onion, sliced
3 to 4 garlic cloves, minced
1 tablespoon fresh ginger, minced or grated
- Use ginger paste from a tube as a shortcut.

Spicy sauce

3 tablespoons low sodium soy sauce
1 tablespoon oyster sauce or hoisin sauce
- Oyster sauce gives more depth; hoisin tastes slightly sweeter.
1 tablespoon rice vinegar or apple cider vinegar
1 to 2 tablespoons chili garlic sauce or sambal oelek
- Start with 1 tablespoon if you prefer medium heat.
1 tablespoon sriracha or your favorite hot sauce
1 to 2 teaspoons brown sugar or honey
- This balances the heat and sharpness of the vinegar.
1 teaspoon toasted sesame oil
1 teaspoon cornstarch mixed with 2 tablespoons water
- This slurry thickens the sauce so it clings to the chicken and peppers.

For cooking

2 to 3 tablespoons neutral oil
- Use canola, avocado, grapeseed, or vegetable oil.
1 teaspoon kosher salt, plus more to taste
1 teaspoon black pepper

Optional toppings

Sliced green onions
Toasted sesame seeds
Red pepper flakes for extra heat
Lime wedges for squeezing over the top

Substitutions and pantry shortcuts

Use frozen sliced bell peppers if fresh ones cost too much or look sad.
Swap soy sauce with tamari or coconut aminos for a gluten friendly version.
Use pre-minced garlic and ginger from jars if you need a speed boost.
Replace chicken with thinly sliced pork, turkey, or extra firm tofu.

Equipment list

Large skillet, sauté pan, or wok
Cutting board and sharp knife
Small bowl for sauce
Tongs or spatula
Measuring spoons and cups

Tips & Mistakes

Slice the chicken thin and evenly so it cooks quickly and stays tender.
Pat the chicken dry before seasoning so it browns instead of steaming.
Heat the pan until it feels hot before you add oil, or the chicken will stick.
Cook the chicken in batches if your pan feels crowded, or it will turn watery.
Keep the peppers slightly crisp; soft peppers make the dish feel tired.
Stir the cornstarch slurry right before adding it so it does not clump.
Taste the sauce before you add it and adjust heat, sweetness, and salt.
Do not walk away once the sauce hits the pan; it thickens fast.
Add sesame oil at the end so the flavor stays bright and nutty.
Avoid over salting early; soy sauce and oyster sauce already bring salt.

How to Make Spicy Chicken With Bell Peppers

Prep the chicken and vegetables

Slice the chicken into thin strips, about 1 quarter inch thick. Pat the strips dry with paper towels, then season with salt and black pepper. Slice the bell peppers and onion into similar sized strips so they cook evenly.

Mince the garlic and ginger, or measure out your jarred versions. Set everything near the stove so you can move quickly once you start cooking. Stir fries reward a little prep work.

Mix the spicy sauce

In a small bowl, add soy sauce, oyster or hoisin sauce, rice vinegar, chili garlic sauce, sriracha, and brown sugar or honey. Stir until the sugar dissolves and the sauce looks smooth. Taste a tiny bit and adjust heat or sweetness.

In another small cup, mix the cornstarch with water until no lumps remain. Keep the sesame oil nearby; you will add it at the end. Set both near the stove.

Sear the chicken

Heat a large skillet or wok over medium high heat until hot. Add 1 to 1.5 tablespoons of oil and swirl to coat the pan. Add half the chicken in a single layer and let it sit for about 1 to 2 minutes so it browns.

Stir and cook until the chicken turns opaque and mostly cooked through, about 3 to 4 minutes total. Transfer the chicken to a plate. Add a little more oil and repeat with the remaining chicken, then set all cooked chicken aside.

Cook the peppers and aromatics

In the same pan, add another small splash of oil if the pan looks dry. Add the sliced onion and bell peppers with a pinch of salt. Stir fry until the peppers soften slightly but still feel crisp, about 3 to 4 minutes.

Push the peppers and onions to the edges of the pan. Add garlic and ginger to the center and cook about 30 seconds until fragrant. Stir everything together so the aromatics coat the vegetables.

Combine chicken and sauce

Return the cooked chicken and any juices to the pan with the peppers. Stir the sauce mixture, then pour it over the chicken and vegetables. Toss everything so the sauce coats each piece.

Give the cornstarch slurry a quick stir and pour it into the pan. Stir constantly for 1 to 2 minutes as the sauce thickens and turns glossy. Turn the heat to low and drizzle in the sesame oil, then toss again.

Adjust and finish

Taste a piece of chicken and a pepper. Add more soy sauce for salt, more chili sauce for heat, or a pinch of sugar if it feels too sharp. If the sauce feels too thick, splash in a tablespoon or two of water and stir.

Sprinkle sliced green onions and sesame seeds over the top if you use them. Turn off the heat and let the stir fry sit for 2 minutes so the flavors settle. Serve hot over your favorite base.

Variations I've Tried

I swap the chicken for thinly sliced beef and keep the same sauce when I crave a spicy pepper steak vibe. I use extra firm tofu, pressed and pan fried until crisp, for a meatless version that still satisfies. I toss in broccoli florets or snap peas with the peppers when I want more vegetables in the pan.

Sometimes I use only red bell peppers and add a small jalapeño or serrano for extra heat and color. I stir in a spoonful of peanut butter to the sauce for a slightly creamy, nutty twist that kids usually love. I also use this same spicy sauce over leftover rotisserie chicken and quick sautéed peppers when I need dinner in a hurry.

How to Serve Spicy Chicken With Bell Peppers

Serve Spicy Chicken With Bell Peppers over steamed jasmine rice, brown rice, or simple white rice for a classic combo. Spoon it over noodles like rice noodles or thin spaghetti for a cozy bowl situation. You can keep it low carb and serve it over cauliflower rice or a bed of sautéed cabbage.

Add cucumber slices or a simple green salad on the side to cool down the heat. If you pack lunches, portion the chicken and peppers with rice into containers so you have grab and go meals that actually taste good.
