Why This Dish Stands Out

- One-pan wonder: From stovetop to table in 25 minutes
- Minimal cleanup: Just a single skillet to wash
- Meal prep superstar: Tastes even better the next day
3. Nutrition-Packed
- High-protein: 35g protein per serving
- Veggie-loaded: Two full cups of colorful bell peppers
- Low-carb/Keto-friendly: Only 8g net carbs per serving

Pro Tips for Perfect Results
Choosing Your Chicken
- Thighs: More flavor and moisture (recommended)
- Breasts: Leaner but can dry out—don’t overcook
Skillet Selection
- Cast iron: Ideal for perfect sear and even heat
- Stainless steel: Great alternative
- Non-stick: Works but won’t develop same fond
Heat Control
- Medium-high for searing
- Reduce to medium when cooking veggies
- If seasoning burns, deglaze with broth
Customization Options
Heat Level Adjustments
- Mild: Omit cayenne, use sweet paprika
- Medium: As written (½ tsp cayenne)
- Fire: Add 1 tsp cayenne + ½ tsp red pepper flakes
Dietary Adaptations
- Keto: Serve over cauliflower rice
- Paleo: Use ghee instead of olive oil
- Dairy-free: Skip optional butter finish
Ingredient Swaps

A: Absolutely! Use 1.5 tbsp of your favorite blend (like Tony Chachere’s), but taste before adding extra salt.
Q: How do I prevent rubbery chicken?
A: Two keys: 1) Don’t overcrowd the pan when searing, and 2) Remove chicken at 165°F internal temp.
Q: What’s the best way to slice bell peppers for this dish?
A: ¼-inch strips—thick enough to stay crisp-tender, thin enough to cook quickly.
