One of the best things about this Chicken Alfredo Tater Tot Casserole is how it transforms a handful of fridge and pantry staples into something truly crowd-pleasing. Each ingredient brings its own magic, making every bite creamy, hearty, and satisfying down to the last tot.

Cooked, shredded chicken: Rotisserie chicken is a time-saver and delivers juicy, flavorful protein.
Alfredo sauce (15 oz jar): Provides the rich, luscious backbone for the casserole; choose your favorite jarred variety or homemade, if you’re feeling ambitious.
Sour cream (1 cup): Adds a tangy creaminess that complements the Alfredo sauce while keeping everything velvety.
Frozen peas (1 cup): Pop in fresh sweetness and a vibrant burst of green; no need to thaw beforehand!
Garlic powder (1 teaspoon): A quick way to amplify savory, aromatic flavor throughout the dish.
Salt (½ teaspoon): Enhances all those cheesy, creamy flavors without overpowering them.
Black pepper (½ teaspoon): Adds just enough warmth and complexity to round out the creamy sauce.
Frozen tater tots (32 oz bag): The ultimate topper—crisp, golden, and oh-so satisfying after baking.
Shredded mozzarella cheese (1 cup): Melts beautifully over the casserole, delivering irresistible pull-apart cheesiness.

How to Make Chicken Alfredo Tater Tot Casserole

Step 1: Prep and Preheat

First things first—preheat your oven to 375°F (190°C). Give your casserole dish a generous coat of nonstick spray so nothing sticks and cleanup is a breeze. This little step sets the stage for a casserole that comes out in those perfect, scoopable portions.

Step 2: Mix the Creamy Base

In a large mixing bowl, stir together the Alfredo sauce, sour cream, garlic powder, salt, black pepper, and peas. Add in the shredded chicken and make sure everything’s thoroughly mixed, so every forkful gets a bit of that creamy, garlicky goodness.

Step 3: Assemble the Casserole

Spoon the chicken mixture evenly into your prepared baking dish, spreading it to the corners so the flavor reaches every inch. Next, arrange the frozen tater tots in a single, even layer right on top. No need to thaw them—the oven will crisp them up beautifully while the casserole bakes.

Step 4: Layer on the Cheese

Scatter the shredded mozzarella all over the tater tots for that gooey, bubbly top layer. This is the step where the magic really happens, so don’t skimp on the cheese if you love an extra-cheesy finish!

Step 5: Bake to Golden Perfection

Pop the casserole into your preheated oven and bake for 35-40 minutes. You’ll know it’s ready when the cheese is melted and golden, the tater tots are crisp, and the creamy base is bubbling up around the edges. Let it rest for a few minutes before serving—it’ll cut neater and taste even better!

How to Serve Chicken Alfredo Tater Tot Casserole

Garnishes

For a pop of color and a fresh finish, sprinkle chopped parsley—or even a little fresh basil—over the top just before serving. A dusting of grated parmesan is always a welcome upgrade if you want to add a nutty, salty flourish right at the table.

Side Dishes

This hearty casserole pairs wonderfully with something light and green. A simple mixed salad with vinaigrette, roasted broccoli, or even garlicky green beans will balance out the richness of the Chicken Alfredo Tater Tot Casserole and round out your meal.

Creative Ways to Present

You can serve this casserole family-style in a big dish, but individual ramekins make a fun and fuss-free option for parties or potlucks. For a slightly fancier twist, pair smaller portions with a drizzle of extra Alfredo sauce or a scatter of crispy fried onions on top.

Make Ahead and Storage

Storing Leftovers

Got leftovers? Scoop them into an airtight container and let them cool to room temperature before refrigerating. Chicken Alfredo Tater Tot Casserole keeps well for up to 3 days, making it perfect for easy lunches or a second round of comfort food magic.

Freezing

You can freeze the assembled, unbaked casserole or leftovers for up to 2 months. Wrap tightly in foil and then plastic wrap to prevent freezer burn. If freezing after baking, let the casserole cool completely first before packaging.

Reheating

To reheat, bake straight from the fridge at 350°F (175°C) until hot and bubbly (about 20 minutes), or microwave individual portions for quicker meals. If reheated from frozen, let it thaw overnight in the fridge before reheating for best results and tater tot crunch.

FAQs

Can I use homemade Alfredo sauce instead of jarred?

Absolutely! If you have a favorite homemade Alfredo sauce, swap it in for the jarred version for a personal touch. Just be sure to use about 15 ounces so the casserole stays nice and creamy.

What vegetables can I add to Chicken Alfredo Tater Tot Casserole?

Peas are great, but you can also stir in cooked broccoli, sautéed mushrooms, or even spinach for more color and nutrients. Just remember to drain any extra moisture from added veggies so your casserole isn’t watery.

Can I make this casserole ahead of time?

Definitely! Assemble the casserole up to a day in advance, cover tightly, and refrigerate. When ready to bake, let it come to room temperature for 20-30 minutes and proceed as directed. This makes prepping for busy nights a breeze.

Are there gluten-free options?

Yes! Simply double-check that your Alfredo sauce, tater tots, and seasonings are gluten-free, and you’re all set. Many frozen tater tot brands now offer gluten-free varieties, so this dish can easily be adapted for dietary needs.

Can I swap the chicken for another protein?

Sure! Leftover turkey, diced ham, or even cooked Italian sausage would all be delicious alternatives to chicken in this casserole. Just keep the same quantities and follow the rest of the recipe as written.
