Chicken Fajita Tater Tot Breakfast Casserole: How It’s Done

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While it’s heating, grab your baking dish and lightly grease it with non-stick spray or butter to prevent sticking.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, combine the milk, heavy cream, eggs, kosher salt, fresh cracked pepper, onion powder, and garlic powder. Whisk until everything is well combined and frothy.
Step 3: Layer the Ingredients
Start layering the base of your casserole. First, place half of the frozen tater tots evenly on the bottom of the greased baking dish. Next, sprinkle half of the diced red and green bell peppers over the tater tots.
Step 4: Add the Chicken
Distribute the sliced or cubed grilled chicken evenly over the bell peppers. This adds a delicious protein element to the casserole.
Step 5: Cheese It Up!
Sprinkle 1 cup of sharp cheddar cheese and 1/2 cup of pepper jack cheese over the chicken layer.
Step 6: Repeat the Layers
Now, repeat the layering process with the remaining tater tots, bell peppers, and chicken. Finally, top it all off with the rest of the cheese.
Step 7: Pour the Egg Mixture
Slowly pour the egg mixture evenly over the layered casserole, ensuring that it seeps down into all the nooks and crannies.
Step 8: Bake to Perfection
Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden brown.
Step 9: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Sprinkle finely chopped green onions and fresh cilantro on top, and serve with sour cream on the side for those who want an extra creamy touch.
