Let’s Get Cooking – Instructions

1. Preheat like you mean it: Set the oven to 425°F (220°C).A hot oven equals charred edges and real fajita vibes.
2. Slice smart: Cut chicken into thin, even strips. Slice peppers and onion into similar-sized pieces so everything cooks in sync.
3. Make the flavor base: In a large bowl, whisk olive oil, lime juice and zest, chili powder, cumin, smoked paprika, garlic powder, oregano, salt, pepper, and cayenne.
4. Toss and coat: Add chicken, peppers, and onion to the bowl. Toss until every piece is shiny and seasoned.No wallflowers.
5. Spread it out: Pour everything onto a large sheet pan and spread in a single layer. Crowding = steaming, not searing. Use two pans if needed.
6. Roast to perfection: Bake for 18–22 minutes, stirring once halfway.Chicken should be cooked through and veggies lightly charred at the edges.
7. Optional sizzle finish: Broil for 2–3 minutes for extra char. Watch closely—broilers go from hero to zero fast.
8. Warm the tortillas: Wrap in foil and pop in the oven for 5 minutes, or toast directly over a gas flame for 10–15 seconds per side.
9. Taste test: Squeeze a little extra lime over the pan and season with a pinch more salt if needed. Acidity and salt are your secret weapons.
10. Serve and top: Load up tortillas with chicken and veggies.Add cilantro, avocado, salsa, and whatever else makes you happy.

Storage Instructions

• Fridge: Store cooked chicken and veggies in an airtight container for up to 4 days. Keep tortillas and toppings separate.
• Reheat: Skillet over medium heat with a splash of water or broth for 2–3 minutes, or microwave in 30-second bursts. Don’t overcook.
• Freezer: Freeze cooked chicken and veggies for up to 2 months.Thaw overnight, then reheat in a hot skillet to revive the texture.
• Meal prep tip: Portion into bowls with rice or quinoa, then add fresh toppings day-of. Future you owes present you a high-five.

Why This is Good for You

• Lean protein for the win: Chicken breast provides protein for muscle repair and steady energy without heavy fat.
• Veggie power: Bell peppers bring vitamin C and antioxidants. Red onion adds prebiotics to support gut health.
• Smart fats: Olive oil helps absorb fat-soluble nutrients and keeps flavors rich without feeling greasy.
• Spices do work: Chili, cumin, and paprika offer anti-inflammatory compounds and serious flavor—no sugar required.
• Customizable carbs: Choose corn tortillas, whole-wheat tortillas, or lettuce wraps based on your goals.Your macros, your rules.

Avoid These Mistakes

• Overcrowding the pan: If ingredients overlap, they steam and turn soggy. Use two pans or a larger one for crisp edges.
• Skipping the lime: Acid brightens everything. Without it, the flavors feel flat.Squeeze before serving.
• Uneven slicing: Thick chicken strips take longer and dry out the thin ones. Keep pieces consistent for even cooking.
• Under-seasoning: Peppers absorb seasoning. Taste after baking and add a pinch of salt and fresh lime to finish.Night and day.
• Cold pan, cold oven: Starting with a properly preheated oven is non-negotiable for that fajita char. Don’t rush it, champ.

Mix It Up

• Protein swaps: Use chicken thighs, shrimp (roast 8–10 minutes), steak strips (broil briefly), or tofu (press and cube; roast 25 minutes).
• Veggie upgrades: Add mushrooms, zucchini, or cherry tomatoes. Keep the pan spacious to maintain those crispy edges.
• Flavor twists: Swap lime for orange-lime, add chipotle in adobo for smoky heat, or sprinkle with Tajín before serving.
• Low-carb version: Serve over cauliflower rice or in lettuce cups with extra salsa and avocado.Still epic, just lighter.
• Cheesy finish: Scatter a little shredded Monterey Jack in the last 2 minutes of baking for a melty, gooey upgrade. Because joy.
• Sauce bar: Offer crema, salsa verde, pickled onions, and hot honey (yes, try it). DIY taco night = instant crowd-pleaser.

FAQ

Can I prep this ahead of time?

Yes.

Slice chicken and veggies, toss with the marinade, and refrigerate up to 24 hours. When you’re ready, spread on a pan and bake. Easy button activated.

How do I keep the chicken from drying out?

Slice evenly, don’t overbake, and let the veggies share the pan—steam from the peppers helps keep moisture.

A quick broil at the end adds char without overcooking.

Are corn or flour tortillas better?

Both work. Corn is naturally gluten-free and adds a toasty flavor; flour is softer and more flexible. Warm either one to make them taste 2x better, IMO.

Can I make it spicier without wrecking the flavor?

Absolutely.

Add extra cayenne, sliced jalapeños to the pan, or a spoon of chipotle in adobo to the marinade. Heat with purpose, not chaos.

What if I don’t have smoked paprika?

Use regular paprika plus a tiny dash of liquid smoke, or just skip it. The chili-cumin-lime combo still slaps, FYI.

What sides go well with fajitas?

Cilantro-lime rice, black beans, elote-style corn, or a simple salad.

Chips and salsa are never a bad idea, unless you fear happiness.
