Ingredients Overview

The beauty of this dish lies in its simplicity and the boldness of the flavors. Here’s a closer look at the key ingredients:

Chicken Breast: Lean and protein-packed, the sliced chicken forms the backbone of this dish. It cooks up tender and soaks up the delicious fajita seasoning.

Bell Pepper & Onion: These classic fajita vegetables bring both color and flavor to the dish. The bell pepper adds sweetness, while the onion provides depth and savory notes.

Zucchini: The zucchini adds a soft texture and mild flavor that complements the peppers and onions perfectly.

Shredded Cheese: You’ll use a generous helping of shredded cheese to top this dish, creating a melty, gooey topping that is simply irresistible.

Fajita Seasoning: The fajita seasoning packet brings that signature smoky, tangy, and slightly spicy kick. It’s the perfect way to flavor the chicken and veggies without needing a bunch of separate spices.

Olive Oil: A couple of tablespoons of olive oil help everything bake evenly and bring a richness to the dish.

Step-by-Step Cooking Instructions

1. Preheat the Oven and Prepare the Baking Sheet:
Start by preheating your oven to 400°F. While the oven is heating up, prepare your baking sheet by lining it with parchment paper or spraying it with non-stick spray for easy cleanup.

2. Combine the Chicken and Veggies:
In a large mixing bowl, combine 1 lb of sliced chicken breast, 1 sliced bell pepper, 1 sliced onion, and 1 sliced zucchini. Add 1 packet of fajita seasoning and 2 tbsp of olive oil to the bowl. Toss everything together to ensure the chicken and vegetables are well-coated with the seasoning and oil.

3. Spread the Mixture on the Baking Sheet:
Spread the seasoned chicken and vegetable mixture evenly on the prepared baking sheet. Make sure the ingredients are in a single layer for even cooking.

4. Top with Shredded Cheese:
Sprinkle 1 cup of shredded cheese over the top of the chicken and veggie mixture. You can use your favorite cheese, such as cheddar or a Mexican blend, for a melt-in-your-mouth finish.

5. Bake Until Done:
Place the baking sheet in the preheated oven and bake for 25-30 minutes, or until the chicken is fully cooked (reaching an internal temperature of 165°F) and the cheese is bubbly and golden.

6. Serve Hot and Enjoy!
Once baked, remove the dish from the oven and serve hot. It’s perfect on its own or with a side of rice, tortillas, or even a fresh green salad.
