- Taco seasoning: Adds a punch of flavor! You can use homemade if you have a stash or any store-bought blend.
- Cream cheese: Gives the casserole a creamy texture; sour cream or Greek yogurt can work too if you want a tangy twist.
- Shredded cheese: Cheddar or a Mexican blend melts beautifully, creating that irresistible cheesy layer.

How to Make the Recipe
- Preheat the oven to 375°F (190°C).
- Cook the chicken: In a large skillet over medium heat, add a touch of oil and cook the chicken until it’s no longer pink. Remove and set aside.
- Sauté the veggies: In the same skillet, add sliced bell peppers and onion. Cook until they’re soft and slightly charred, about 5-7 minutes.
- Mix with seasoning: Stir in the taco seasoning and return the chicken to the skillet. Mix everything well.
- Cream it up: Add in the cream cheese and stir until it’s melted and evenly coated over the chicken and veggies.
- Layer it up: Pour the mixture into a baking dish, then sprinkle the shredded cheese on top. Add crushed tortilla chips if using.
- Bake: Place the dish in the oven and bake for about 15-20 minutes, until everything is bubbly and golden.
- Garnish and serve: Top with fresh cilantro before serving, if desired.
Pro Tips for Making the Recipe
- Prep ahead: Chop your veggies and cook the chicken the day before to save time.
- Cheesy variations: Feel free to mix in your favorite types of cheese for extra flavor—pepper jack adds a nice kick!
- Add some heat: Toss in sliced jalapeños or a pinch of cayenne for a spicy twist.
- Skipping tortillas?: You can also serve this over rice for a hearty meal.
- Don’t overcook: Keep an eye on the chicken; it can dry out if overcooked.
How to Serve
This casserole is delicious on its own, but feel free to serve it with sides like rice, a fresh green salad, or even some warm corn tortillas. A dollop of sour cream or avocado on top can elevate the dish even further!
Make Ahead and Storage
- Fridge storage: Allow leftovers to cool before storing in an airtight container. It lasts for about 3-4 days.
- Freezing: This casserole freezes well! Just let it cool completely, then wrap tightly and store in the freezer for up to 2 months.
- Reheating tips: Reheat in the oven for the best results, but the microwave works too. Just be sure to cover it to prevent it from drying out!
