- Chicken Breasts: They’re the main protein in the dish and provide the hearty base for the sweet-and-savory stir fry.
- Soy Sauce: Provides the salty, umami backbone of the stir fry sauce, balancing the pineapple’s sweetness.
- Sweet Chili Sauce: Adds sweetness with a mild heat, helping create the sticky, flavorful glaze for the chicken.
- Tempura Mix: Creates the light, crispy coating on the chicken, adding texture that contrasts with the sauce.
- Bell Peppers & Red Onion: Bring color, freshness, and slight sweetness while adding crunch to balance the crispy chicken and sauce.
Variations
- Make It Extra Spicy: Add additional chili crisp or red pepper flakes to the sauce.
- Add More Vegetables: Try adding broccoli, carrots, mushrooms, baby corn, water chestnuts, or bamboo shoots.

How to Make Spicy Chicken Stir Fry

Step 1: Cut the chicken into 1-inch cubes. Then, toss them in half the tempura mix until coated.

Step 2: Mix the remaining tempura with cold water. Then, just before frying, dip the chicken into the wet mixture.

Step 3: Fry the chicken in hot oil in batches until golden and crispy.

Step 4: Whisk the sauce ingredients and set aside.

Step 5: Saute the onions over medium-high heat until fragrant. Then, add the bell peppers until bright and slightly softened.

Step 6: Add the remaining veggies and cook until tender-crisp.

Step 7: Add the sauce and bring to a boil.

Step 8: Remove from the heat, add the chicken, and toss to coat. Enjoy with rice, noodles, or as is.
Expert Tips
- Keep the Oil Hot: Maintaining the oil temperature ensures the chicken cooks up crispy rather than greasy.
- Prep Ingredients First: Stir fry recipes cook quickly, so having everything chopped and ready makes the process smoother.
- Don’t Overcrowd the Pan: Cooking vegetables in batches prevents them from steaming instead of sautéing.
- Use Fresh Ginger and Garlic: Fresh ingredients add far more flavor than their powdered counterparts.
- Use a Wok or Heavy-Bottomed Skillet: The dish cooks quickly over high heat. Use a pan that can stand up to that.
