  • 1 green bell pepper, thinly sliced

  • 1 medium red onion, thinly sliced

  • 1 tablespoon olive oil

For the Cheesy Topping:

  • 1 ½ to 2 cups shredded cheese, such as:

    • Mexican blend

    • Pepper Jack

    • Mozzarella + cheddar combo

  • ¼ cup fresh cilantro, chopped (for garnish)

🍽️ Equipment Needed

  • Large oven-safe baking dish (9×13 works well)

  • Small mixing bowl

  • Large bowl for tossing veggies

  • Knife and cutting board

  • Tongs or spatula

  • Aluminum foil (optional, for covering during baking)

⏲️ Time Overview

  • Prep Time: 15 minutes

  • Bake Time: 25–30 minutes

  • Rest Time: 5 minutes

  • Total Time: ~45–50 minutes

👨‍🍳 Step-by-Step Instructions

🔪 Step 1: Preheat and Prep the Chicken

  1. Preheat your oven to 400°F (200°C).

  2. Lightly grease your baking dish with a little olive oil or nonstick spray.

  3. Trim and pat dry the chicken breasts with paper towels.

🧂 Step 2: Make the Fajita Seasoning

In a small bowl, mix together the spices:

  • 1½ tsp chili powder

  • 1 tsp smoked paprika

  • 1 tsp garlic powder

  • 1 tsp onion powder

  • ½ tsp cumin

  • ½ tsp oregano

  • ½ tsp salt

  • ¼ tsp black pepper

🔥 Tip: Add a pinch of cayenne if you like some heat!

Rub this seasoning all over the chicken breasts. Drizzle with 1 tbsp olive oil and 1 tbsp lime juice, and let it marinate for 10–15 minutes while you prep the veggies.

🫑 Step 3: Slice and Season the Veggies

  1. Thinly slice the bell peppers and onion.

  2. In a bowl, toss the veggies with 1 tbsp olive oil and a pinch of salt and pepper.

  3. Layer the seasoned veggies in your baking dish to form a colorful bed for the chicken.

🌈 Bonus: Use multi-colored peppers for a more vibrant, restaurant-style look.

🍗 Step 4: Assemble the Dish

  1. Place the seasoned chicken breasts on top of the bell pepper and onion layer.

  2. Make sure they’re nestled nicely so the veggies roast evenly underneath.

Optional: If your chicken breasts are very thick, consider slicing them horizontally (butterflying) so they cook more evenly and absorb more flavor.

🔥 Step 5: Bake

  1. Place the dish in the preheated oven and bake uncovered for 20–25 minutes, depending on the thickness of your chicken.

  2. Check for doneness: chicken should reach internal temp of 165°F (74°C) and be juicy inside.

🧄 Tip: You’ll start to see the edges of the veggies slightly char and caramelize — that’s where the flavor is!

🧀 Step 6: Add the Cheese

  1. Once the chicken is cooked through, remove the dish from the oven.

  2. Sprinkle your shredded cheese generously over the chicken and veggies.

  3. Return to the oven for 5–7 minutes, or until the cheese is melted and bubbly.

    • For golden cheese, broil on high for an additional 2–3 minutes, watching closely.

🌿 Step 7: Garnish and Rest

  1. Remove from the oven and let rest for 5 minutes before serving.

  2. Sprinkle with chopped cilantro, or parsley if preferred.
