What Ingredients You Will Need

This Creamy Chicken Alfredo Tater Tot Casserole calls for simple, wholesome ingredients that you can find at any grocery store. Here’s what you’ll need:

Cooked chicken: About 3 cups, shredded or diced. Rotisserie chicken works great for this recipe!
Alfredo sauce: 1 jar (15 oz). Use your favorite brand or try homemade if you have time.
Sour cream: 1 cup for extra creaminess.
Garlic powder: 1 teaspoon for a subtle kick.
Italian seasoning: 1 teaspoon for those savory, herby flavors.
Shredded mozzarella cheese: 2 cups (divided). This adds that gooey, cheesy goodness.
Frozen tater tots: 1 bag (32 oz). The star of the show—crispy and golden!
Optional: Fresh parsley, chopped (for garnish).

If you’re looking for substitutions, you can swap sour cream with plain Greek yogurt for a slightly tangier flavor. For a lower-carb version, try cauliflower tots instead of traditional tater tots. Don’t forget to use cooked chicken—leftovers or rotisserie chicken work perfectly!

Equipment Needed

Here’s what you’ll need to make this casserole:

9×13-inch baking dish: Perfect for layering and baking everything evenly.
Mixing bowls: For combining the creamy sauce and chicken mixture.
Wooden spoon or spatula: To stir your mixture without scratching your bowls.
Cheese grater: If you’re grating mozzarella fresh.
Optional: A knife and cutting board for shredding chicken if not pre-shredded.

If you don’t have a 9×13-inch dish, a similar-sized casserole dish will work just fine. And if you’re short on mixing bowls, you can mix everything directly in the baking dish—it’s one less dish to wash!

How to Make Creamy Chicken Alfredo Tater Tot Casserole

Preheat the oven: Set your oven to 375°F (190°C).
Prepare the sauce: In a mixing bowl, combine the Alfredo sauce, sour cream, garlic powder, Italian seasoning, and 1 cup of shredded mozzarella cheese. Stir until smooth.
Add the chicken: Fold the shredded or diced cooked chicken into the sauce mixture, ensuring it’s fully coated.
Assemble the casserole: Pour the chicken and sauce mixture into your 9×13-inch baking dish, spreading it evenly.
Layer the tater tots: Arrange the frozen tater tots on top of the chicken mixture in a single layer.
Add the cheese: Sprinkle the remaining cup of shredded mozzarella cheese over the tater tots.
Bake: Place the casserole in the oven and bake for 40-45 minutes, or until the tater tots are golden and crispy, and the cheese is melted and bubbly.
Garnish and serve: Remove from the oven and let it cool for 5 minutes. Sprinkle with fresh parsley before serving for a pop of color and flavor.

This casserole is best enjoyed warm, with all the flavors melding together beautifully. If you notice the tater tots aren’t as crispy as you’d like, simply broil the casserole for an additional 2-3 minutes.

Cooking Tips & Techniques

Here are some tips to make your Creamy Chicken Alfredo Tater Tot Casserole absolutely foolproof:

Don’t skip preheating: Starting with a hot oven ensures your tater tots crisp up perfectly.
Use fresh cheese: If possible, grate your mozzarella at home—it melts smoother and tastes richer.
Frozen tater tots: Keep them frozen until ready to use for the best texture.
Mix evenly: Make sure the chicken is completely coated with the Alfredo sauce mixture to keep every bite flavorful.
Broil for crispiness: If you love extra crispy tater tots, broil the casserole for 2-3 minutes at the end.

And lastly, don’t be afraid to taste the sauce before assembling the casserole. You can adjust the seasonings to your liking—add a dash of salt or pepper if needed!

Variations & Adaptations

This recipe is incredibly versatile. Here are a few ideas to make it your own:

Low-carb option: Swap out tater tots for cauliflower tots or zucchini slices.
Vegetarian twist: Replace chicken with sautéed mushrooms, spinach, or broccoli for a veggie-packed version.
Spicy kick: Add a teaspoon of crushed red pepper flakes to the Alfredo sauce for a hint of heat.
Different cheeses: Try swapping mozzarella for cheddar, Parmesan, or a blend of Italian cheeses.
Make it smoky: Use smoked chicken or smoked Gouda for a unique flavor profile.

Personally, I’ve tried adding chopped sun-dried tomatoes to the sauce, and it adds a tangy sweetness that complements the creaminess beautifully. Get creative and make it your own!

Serving & Storage Suggestions

This casserole is best served warm, fresh out of the oven. Here’s how to make the most of it:

Serving temperature: Serve immediately for the crispiest tater tots and gooey cheese.
Pair it with: A simple green salad or steamed veggies to balance the richness.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating: Warm individual portions in the oven at 350°F (175°C) or in the microwave for 1-2 minutes.
Freezing: You can freeze the unbaked casserole for up to 1 month. Thaw overnight in the fridge and bake as directed.

One thing to note—the flavors deepen over time, so leftovers taste just as good (if not better) the next day!
