Chili Chicken Stir Fry Recipe
Introduction
This Chili Chicken Stir Fry is a vibrant, flavorful dish perfect for a quick weeknight dinner. Tender chicken is seasoned with chili and garlic, then cooked with colorful bell peppers and fire-roasted tomatoes for a satisfying meal with a kick.

Ingredients
- 1 lb chicken breasts, skinless and boneless, thinly sliced (substitute with chicken thighs or firm tofu for a vegetarian option)
- 1 tbsp garlic powder
- 2 tbsp chili powder (reduce to 1 tbsp for milder heat or substitute smoked paprika for subtler flavor)
- Salt and black pepper, to taste
- 2 tbsp avocado oil (or olive oil)
- 2 green bell peppers, thinly sliced (or red, yellow, or orange bell peppers)
- 1 white onion, thinly sliced (or yellow or red onion)
- 3 cloves garlic, minced (or garlic powder/flakes)
- 2 (14 oz) cans fire-roasted diced tomatoes (or regular diced tomatoes)
- 2 tbsp Parmesan cheese, grated (or Asiago cheese or nutritional yeast for a plant-based option)
Instructions
- Step 1: In a large bowl, combine the sliced chicken, garlic powder, chili powder, salt, and black pepper. Mix well to coat the chicken evenly with the spices.
- Step 2: Heat a skillet over medium-high heat and add the avocado oil. Add the seasoned chicken and cook, stirring consistently, for 7-10 minutes until the chicken is mostly cooked through.
- Step 3: Add the sliced bell peppers, onions, and minced garlic to the skillet. Stir to combine all ingredients.
- Step 4: Pour in the fire-roasted diced tomatoes and cover the pan with a lid. Let everything simmer for 5 minutes, stirring occasionally.
- Step 5: Check that the chicken is fully cooked and the peppers are tender. If the mixture starts to burn, reduce the heat. Mix well before removing from heat.
- Step 6: Serve hot, garnished with grated Parmesan cheese or your preferred topping.
Tips & Variations
- For a vegetarian version, substitute chicken with firm tofu and add extra spices to boost flavor.
- Try mixing different colored bell peppers for a more colorful presentation and varied sweetness.
- Using fire-roasted tomatoes adds a smoky depth; if unavailable, regular tomatoes work but adjust seasoning accordingly.
- Parmesan cheese can be swapped with Asiago or nutritional yeast for a vegan-friendly option.
- If you prefer less heat, reduce chili powder to 1 tablespoon or replace it with smoked paprika.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat or microwave until warmed through. Avoid overcooking when reheating to keep the chicken tender.

FAQs
Can I use chicken thighs instead of breasts?
Yes, chicken thighs work well and stay juicy during cooking. Just slice them thinly and follow the same spice and cooking instructions.
What can I use if I don’t have fire-roasted diced tomatoes?
You can substitute regular canned diced tomatoes. While the smoky flavor will be less pronounced, the dish will still be delicious. Consider adding a small pinch of smoked paprika to mimic the fire-roasted taste.
