How to Make Chicken Alfredo Tater Tot Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and make clean-up easy later on.
Step 2: Mix the Filling
In a large bowl, combine the shredded cooked chicken, Alfredo sauce, sour cream, frozen peas, garlic powder, salt, and black pepper. Stir well until all the ingredients are evenly mixed and the creamy sauce coats each piece of chicken perfectly.
Step 3: Spread the Mixture
Transfer the creamy chicken mixture into your prepared baking dish and spread it out evenly with a spatula. This ensures every slice of casserole will have a bit of that heavenly filling.
Step 4: Add the Tater Tots
Next, arrange the frozen tater tots on top in a single, even layer. These will bake up golden and crispy, creating the perfect contrast to the creamy base below.
Step 5: Bake Until Bubbling and Golden
Bake uncovered for 30 to 35 minutes. You’ll want to see the edges bubbling with creamy goodness and the tater tots turning that irresistible golden-brown color.
Step 6: Add the Cheese Topping
Once baked, pull the casserole out of the oven and sprinkle the shredded mozzarella cheese all over the top. This cheesy layer is about to make this dish next-level delicious.
Step 7: Final Bake for Melty Cheese
Return the casserole to the oven for an additional 5 to 10 minutes. Watch closely as the mozzarella melts, bubbles, and starts to turn a slight golden shade—that’s when you know it’s ready.
Step 8: Let It Rest Before Serving
Allow the casserole to rest for a few minutes before serving. This little pause helps everything set nicely, making it easier to slice and enjoy every flavorful bite.
How to Serve Chicken Alfredo Tater Tot Casserole Recipe

Garnishes
Fresh herbs like chopped parsley or basil are wonderful garnishes, adding a pop of vibrant color and a fresh flavor kick that brightens up the creamy richness of this casserole.
Side Dishes
Pair this hearty casserole with a crisp green salad or some steamed vegetables to balance the indulgence. A simple Caesar salad or roasted asparagus works beautifully alongside.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins or mini cast-iron skillets. This makes the Chicken Alfredo Tater Tot Casserole Recipe feel extra special—perfect for dinner parties or cozy nights in.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. The casserole will stay good for up to 3 days, making for an easy and comforting lunch or dinner the next day.
Freezing
This casserole freezes exceptionally well. Assemble and freeze it before baking, wrapped tightly in plastic and foil. When you’re ready, bake it covered with foil at 375°F until heated through, then uncover and add cheese to finish.
Reheating
To reheat, warm individual portions in the microwave or the entire casserole in the oven at 350°F until hot and bubbly. Adding a minute or two under the broiler can crisp up the tater tot topping again for that fresh-out-of-the-oven feel.
FAQs
Can I use homemade Alfredo sauce for this recipe?
Absolutely! Homemade Alfredo sauce adds an extra touch of freshness and lets you control the flavors. Just make sure it’s thick enough to hold the casserole together nicely.
What kind of chicken works best?
Leftover roasted chicken or rotisserie chicken shredded into bite-sized pieces works wonderfully, saving you prep time and adding great flavor complexity.
Can I substitute the peas for other vegetables?
Yes! Feel free to swap peas with broccoli florets, diced carrots, or even corn—anything that adds a bit of color and texture to this creamy casserole.
Is this recipe suitable for freezing after it’s baked?
While you can freeze leftovers after baking, the tater tots may lose some of their crispiness. Freezing before baking often yields a better texture when reheated.
How can I make this recipe spicier?
Add a pinch of crushed red pepper flakes or a dash of cayenne pepper to the filling mixture. You can also top the finished dish with sliced jalapeños for a flavorful kick.
