Full Recipe Ingredients
- 1.5 lbs boneless, skinless chicken breasts, sliced into 1/2-inch strips
- 3 large bell peppers (red, yellow, and green), sliced into uniform strips
- 1 large red onion, thinly sliced
- 3 tbsp avocado oil
- 2 tbsp fajita seasoning (or your favorite taco seasoning)
- 1 tsp smoked paprika
- 1/2 tsp kosher salt
- 1 lime, juiced
- 1/2 cup fresh cilantro, chopped
- 8 small flour tortillas, warmed
The 4 Steps to Perfection
Step 1: Prep the Aromatics
Start by slicing your peppers and onions into uniform strips to ensure they reach tenderness at the same rate. Place these on your sheet pan, tossing them with a tablespoon of oil (don't crowd the pan, as you want them to roast, not steam!). A crowded pan leads to soggy vegetables, so give them room to caramelize.
Step 2: Season the Chicken
In a large glass bowl, combine the sliced chicken with the remaining oil, fajita seasoning, and smoked paprika. Massage the spices into the meat thoroughly, ensuring every strip is coated (this ensures the seasoning adheres during the high-heat blast).
Step 3: Roast to Perfection
Arrange the seasoned chicken in a single layer alongside the peppers. Slide the pan into a preheated 425°F oven and roast for 18–20 minutes. Keep an eye out for that Maillard reaction—the browning on the chicken and the slight char on the edges of the peppers is exactly what you’re looking for to build depth.
Step 4: Finish and Serve
Remove from the oven and immediately squeeze the fresh lime juice over the hot mixture, which will deglaze the pan and pick up those caramelized bits of fond (the concentrated flavor stuck to the pan). Garnish with cilantro and serve immediately with warmed tortillas for the perfect sheet pan fajitas experience.
