Ingredients to Make Chicken Breakfast Bake:
- cooked chicken. Use cooked, shredded, or diced chicken. Rotisserie chicken works well for convenience. You can also use leftover grilled or baked chicken for extra flavor.
- red bell pepper. Adds a slight sweetness and vibrant color. You can substitute with green, yellow, or orange bell pepper.
- onion. Enhances the flavor with a slight sweetness when cooked. A white, yellow, or red onion all work well.
- eggs. Bind the ingredients together while adding protein and a fluffy texture.
- fresh jalapeño pepper. Adds a mild to medium heat. For a spicier kick, leave the seeds in or swap for serrano pepper. If you prefer less spice, omit it entirely.
- cheddar cheese. Provides a rich, cheesy flavor. Feel free to substitute with Monterey Jack, pepper jack, or mozzarella.

How to Make Chicken Breakfast Bake:
- Preheat oven to 375°F. Grease an 8×8 baking dish.
- In a large skillet over medium heat, cook the onion, bell pepper, and jalapeño until softened.
- Whisk eggs in a medium bowl and season with salt and black pepper.
- In the greased baking dish, layer the cooked chicken, sautéed vegetables, and shredded cheese.
- Pour eggs over the mixture evenly.
- Bake for 20-25 minutes or until the eggs are set and the top is golden brown.

Recipe Notes & Tip:
- Sautéing the Vegetables: Cooking the onions, bell peppers, and jalapeños before baking helps enhance their flavor and prevents excess moisture in the dish.
- Shredded vs. Diced Chicken: Shredded chicken blends well throughout the bake, while diced chicken gives chunkier bites. Either works!
- Cheese Variations: Try swapping cheddar for a mix of Monterey Jack, mozzarella, or pepper jack for extra flavor.
- Spice Level Adjustment: For more heat, leave some jalapeño seeds in or add a pinch of red pepper flakes. To reduce spice, omit the jalapeño.
- Make it a Full Meal – Serve with avocado slices, salsa, or a dollop of sour cream for extra flavor.

Serving Suggestions:
How to Store:
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days. Let it cool completely before storing to prevent condensation and sogginess.
Freezing: For longer storage, wrap individual portions tightly in plastic wrap and place them in a freezer-safe bag or container. Freeze for up to 2 months.
Reheating: Reheat in the oven at 350°F for 10-15 minutes or microwave in 30-second intervals until warm.
Make Ahead: Make ahead by assembling the bake the night before, cover, and refrigerate; bake fresh in the morning.

FAQs:
No, the chicken needs to be pre-cooked. You can use rotisserie chicken, grilled, or baked chicken for convenience.
Absolutely! Spinach, mushrooms, or zucchini would make great additions.
Simply omit the cheese or use a dairy-free cheese alternative.
