Cooking Chicken Fajita Tater Tot Breakfast Casserole: The Process

Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This ensures that your casserole will cook evenly and come out perfectly crispy.
Step 2: Prepare 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 well blended and set aside.
Step 3: Layer the Chicken and Peppers
In your baking dish, spread the grilled chicken pieces evenly across the bottom. Then, sprinkle the diced red and green bell peppers over the chicken, allowing their vibrant colors to shine through.
Step 4: Add the Cheese
Next, layer the sharp cheddar cheese and pepper jack cheese over the chicken and peppers. This cheesy layer is going to create a deliciously gooey texture that binds everything together.
Step 5: Top with Tater Tots
Carefully arrange the frozen tater tots over the cheesy mixture. It’s okay if they overlap a little; they will crisp up beautifully during baking.
Step 6: Pour the Egg Mixture
Now, pour the creamy egg mixture evenly over the tater tots. This will soak into all the layers, creating a wonderfully rich flavor.
Step 7: Bake to Perfection
Place the casserole in your preheated oven and bake for 45-50 minutes, or until the tater tots are golden brown and crispy, and the egg mixture is set.
Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Top with finely chopped green onions, and serve with fresh cilantro and a dollop of sour cream.
Seasonal Flavor Boosts

- Add diced jalapeños for a spicy kick.
- Swap out bell peppers for seasonal veggies like zucchini or spinach.
- Use your favorite flavored cheese, like chipotle cheddar, to enhance the taste.
- Incorporate avocado slices for a creamy texture and fresh taste.
Steer Clear of These
When making your Chicken Fajita Tater Tot Breakfast Casserole, avoid using stale or frozen ingredients past their prime. Fresh veggies and quality cheese will yield the best flavor. Additionally, steer clear of overly seasoned chicken, as it may overpower the dish.
How to Store & Reheat
If you have leftovers (which I doubt will happen!), store the casserole in an airtight container in the refrigerator for up to 3 days. To reheat, simply place a portion in the microwave for about 1-2 minutes, or until warmed through. You can also reheat it in the oven at 350°F (175°C) for about 10-15 minutes, covered with foil to retain moisture.
Top Questions & Answers
Can I use fresh chicken instead of grilled chicken?
Absolutely! You can grill or sautĂ© fresh chicken breast before adding it to the casserole. Just make sure it’s cooked thoroughly before layering it in.
Can I make this casserole ahead of time?
Yes! You can assemble the casserole the night before and store it in the fridge. Just pop it in the oven in the morning, adding a few extra minutes to the baking time if it’s cold from the fridge.
What can I substitute for heavy cream?
If you’re looking for a lighter option, you can substitute half and half or even whole milk. However, using heavy cream gives the casserole a rich, creamy texture that is hard to beat.
Can I freeze leftovers?
Yes, you can freeze the casserole for up to 2 months. Just make sure to wrap it tightly in plastic wrap and then foil. When you’re ready to eat, thaw it overnight in the fridge before reheating.
