Pat the chicken breasts dry with paper towels. In a bowl, toss the chicken with:
-
Olive oil
-
Fajita seasoning
Rub the seasoning evenly over both sides for maximum flavor.
Step 3: Prepare the Vegetables
Slice the bell peppers and onion into thin strips. Toss them lightly with a drizzle of olive oil and a pinch of salt and pepper if desired.
Step 4: Assemble the Dish
Arrange the seasoned chicken breasts in the baking dish. Scatter the sliced peppers and onions evenly over and around the chicken.
Step 5: Bake
Cover the dish loosely with foil and bake for 25–30 minutes, or until the chicken is nearly cooked through (internal temperature around 160°F / 71°C).
Step 6: Add the Cheese
Remove the foil. Sprinkle shredded cheese generously over each chicken breast and some over the vegetables.
Return the dish to the oven uncovered and bake for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden.
Step 7: Garnish & Serve
Remove from the oven and let rest for 5 minutes. Garnish with fresh cilantro, squeeze of lime, or jalapeños if desired.
Serve hot and enjoy!
