Ingredients
Method
- Preheat and prep: Heat your oven to 425°F (220°C).Line a large sheet pan with parchment for easy cleanup.
- Slice the chicken: Cut chicken into 1/2-inch strips against the grain. Pat dry with paper towels for better browning.

- Toss the veggies: In a large bowl, add peppers, onion, and jalapeño (optional). Drizzle with half the oil and half the seasoning.Toss to coat.
- Season the chicken: In another bowl, add chicken, remaining oil, remaining seasoning, minced garlic, and lime juice. Toss until evenly coated.
- Arrange on the pan: Spread veggies on one side and chicken on the other in a single layer. Avoid overcrowding so everything roasts instead of steaming.
- Roast: Bake for 15–18 minutes, flipping halfway.Chicken is done when it reaches 165°F (74°C) internally and is lightly browned on the edges.
- Broil for char (optional): Turn the broiler to high for 2–3 minutes to get that fajita-style char on the peppers and chicken. Watch closely.
- Finish with freshness: Squeeze extra lime juice over the pan and sprinkle with chopped cilantro.
- Portion for meal prep: Divide into 4–5 containers with your choice of base—about 3/4 to 1 cup cooked grain or cauliflower rice per serving. Add toppings right before eating, not during storage.

Storage Instructions
- Refrigerator: Store in airtight containers for up to 4 days.
- Freezer: Freeze chicken and veggies (without rice or toppings) for up to 2 months.
Thaw overnight in the fridge before reheating.
- Reheating: Microwave 60–90 seconds, stirring halfway. Or reheat in a skillet over medium heat for 4–6 minutes with a splash of water or broth to keep it juicy.
- Keep toppings separate: Store salsa, yogurt, avocado, and lettuce separately to prevent sogginess.
Health Benefits
- Lean protein for muscle and satiety: Chicken breast offers high-quality protein that helps keep you full and supports recovery.
- Fiber and antioxidants: Bell peppers and onions provide vitamin C, carotenoids, and fiber for immune support and gut health.
- Smart fats: Olive or avocado oil adds heart-healthy monounsaturated fats.
- Lower sodium than takeout: Homemade seasoning helps control salt, and lime adds bright flavor without extra sodium.
- Flexible carbs: Choose whole grains for lasting energy or cauliflower rice for a lower-carb option.
What Not to Do
- Don’t overcrowd the pan: Crowding causes steaming, which leads to soggy veggies and pale chicken. Use two pans if needed.
- Don’t skip drying the chicken: Excess moisture prevents browning and can make it rubbery.
- Don’t add toppings in advance: Avocado, salsa, and yogurt can water down the meal during storage.
- Don’t overcook: Dry chicken is the fastest way to ruin meal prep.
Use a thermometer and pull it at 165°F (74°C).
- Don’t forget acid: The final lime squeeze brightens the whole dish and balances the spices.
Variations You Can Try
- Chicken thigh fajitas: Swap breasts for boneless thighs for richer flavor and extra tenderness. Adjust cook time by 2–3 minutes if pieces are thicker.
- Sheet-pan shrimp: Roast peppers and onions first for 10 minutes, then add seasoned shrimp for the last 6–8 minutes.
- Low-carb bowls: Serve over cauliflower rice with shredded lettuce, avocado, and a dollop of Greek yogurt.
- High-fiber grain bowls: Use quinoa or farro and add black beans or pinto beans for more fiber and plant protein.
- Extra veg boost: Add zucchini or mushrooms in the last 10 minutes of roasting for more volume without many calories.
- Smoky chipotle twist: Stir 1–2 teaspoons chipotle in adobo into the marinade for deeper heat and smokiness.
- Dairy-free creamy finish: Blend avocado with lime, cilantro, and a splash of water for a light, dairy-free crema.
FAQ

This recipe makes about 4–5 meal prep portions, depending on your side choices and how much chicken you use.
Can I make this on the stovetop?
Yes. Heat a large skillet over medium-high with a bit of oil.
Sear the chicken strips 4–6 minutes until cooked through, remove, then sauté peppers and onions until tender with charred edges. Combine and finish with lime.
What if I don’t have smoked paprika?

Add a teaspoon of water or broth to the container before microwaving, and cover loosely.
Heat in short bursts, stirring once, just until hot.
