Step by step
Tap a step to cross it offSlice Vegetables & Chicken
Preheat oven to 425°F. Slice 1.5 lbs boneless chicken breasts into 1/2-inch strips. Slice 3 colorful bell peppers (red, yellow, orange) and 1 yellow onion into uniform strips.
WhyUniform slicing ensures the chicken and peppers finish roasting at the exact same second.
Direct-Pan Seasoning
Pile chicken and veggies onto a parchment-lined baking sheet. Drizzle with 2 tbsp oil, 1 tbsp chili powder, 1 tsp cumin, 1 tsp garlic powder, 1 tsp smoked paprika, 1 tsp salt, and 1/2 tsp pepper. Toss with tongs.
WhySeasoning directly on the sheet pan saves an extra mixing bowl from the sink.
Roast with Ample Space
15 min · flip at 8Spread mixture into a single flat layer across the entire sheet pan. Roast for 15 minutes at 425°F, using tongs to stir once halfway through.
WhyIf your pan is overcrowded, split between two pans. Crowding leads to steaming instead of roasting.
Broiler Char & Table Service
Turn broiler to HIGH for 2 minutes to create blistered, smoky edges on the peppers. Squeeze fresh lime juice over everything and serve with warm tortillas.
WhyWatch the broiler closely—2 minutes transforms the flavor from roasted to authentic sizzling fajita char.
