Why You’ll Love Sheet Pan Fajitas
One-Pan Cleanup: No oily stovetop splatters. Everything roasts on a single baking sheet.
Healthy & Protein-Packed: Loaded with colorful bell peppers, onions, and lean protein.
Highly Customizable: Easily adaptable for keto, low-carb, vegetarian, or vegan diets.
Perfect for Meal Prep: These veggies and proteins stay juicy even after reheating.
The Ingredients
To achieve maximum flavor, fresh ingredients and a robust spice blend are key.
1. The Protein
You can use flank steak, chicken breast, or shrimp. The trick is to slice beef or chicken into thin, even strips so they cook at the same rate as the vegetables.
2. The Veggie Trio
Traditional fajitas rely on the "holy trinity" of peppers:
Red, Yellow, and Green Bell Peppers (sliced into strips).
Red Onion (sliced into wedges).
3. The Signature Fajita Seasoning
Skip the store-bought packets and mix your own for better flavor control:
Chili powder and Cumin (for earthiness).
Smoked Paprika (for that "grilled" aroma).
Garlic powder, Onion powder, Salt, and Pepper.
A pinch of Cayenne (optional, for heat).
Step-by-Step Instructions
Preheat & Prep: Heat your oven to 200°C (400°F). Line a large rimmed baking sheet with parchment paper or foil for the easiest cleanup.
Toss: Place your protein and sliced vegetables directly on the sheet pan. Drizzle with olive oil and sprinkle your spice blend generously over everything. Toss with your hands or tongs until evenly coated.
Spread: Ensure everything is in a single layer. If the pan is too crowded, the ingredients will steam instead of roast, and you’ll miss out on those delicious charred edges.
Roast: Bake for 18–22 minutes. If using shrimp, add them halfway through as they cook faster than chicken or steak.
The Finishing Touch: Squeeze fresh lime juice over the pan immediately after removing it from the oven. This "wakes up" all the spices.
Serving Suggestions
Serve your sheet pan fajitas family-style right off the tray! Pair them with:
Warm Tortillas: Flour, corn, or lettuce wraps.
Toppings: Fresh cilantro, sliced avocado or guacamole, sour cream, and salsa verde.
Sides: Cilantro lime rice or seasoned black beans.
Pro Tips for Success
Tip: If you love a bit of char, turn on the broiler for the last 2 minutes of cooking. Keep a close eye on it to prevent burning!
How to Store and Reheat
Store leftovers in an airtight container in the fridge for up to 4 days. To reheat, a quick toss in a hot skillet for 2 minutes will help maintain the texture better than a microwave.
