Ingredients

Gathering your ingredients is half the fun, and with this recipe, it’s super simple!

3 cups shredded cooked chicken: Rotisserie chicken is your best friend here for ultimate ease, but leftover cooked chicken works perfectly too!
1 (15 ounce) jar Alfredo sauce: The creamy backbone of our casserole. Pick your favorite brand!
1 cup sour cream: This adds a lovely tang and extra creaminess.
1 cup frozen peas: A pop of color and a bit of freshness. No need to thaw them!
1 teaspoon garlic powder: Because what’s a savory casserole without a hint of garlic?
½ teaspoon salt: Just to enhance all those delicious flavors.
½ teaspoon black pepper: A little kick to wake up your taste buds.
1 (32 ounce) bag frozen tater tots: The star of the show! These get perfectly crispy.
1 cup shredded mozzarella cheese: For that gooey, cheesy topping we all adore.

How to Make It

Alright, let’s get cooking! You’ve got this.

First things first, preheat your oven to 375°F (190°C). It needs to be nice and toasty.
Grab a big bowl. This is where the magic happens! Toss in your shredded chicken, that jar of Alfredo sauce, the sour cream, those frozen peas, garlic powder, salt, and black pepper. Give it all a good stir until everything is beautifully combined and coated.
Now, take your 9×13 inch baking dish and spread that yummy chicken mixture evenly across the bottom. Make sure it’s a nice, even layer so every bite is perfect.
Time for the tater tots! Arrange them in a single layer over the chicken mixture. I like to tuck them in snugly, but make sure they’re not overlapping too much so they can get nice and crispy.
Sprinkle that shredded mozzarella cheese all over the tater tots. Don’t be shy – more cheese is always a good idea!
Pop that dish into your preheated oven and bake for 25-30 minutes. You’re looking for those tater tots to turn a gorgeous golden brown and get wonderfully crispy, and for the casserole underneath to be all bubbly and heated through.
Once it’s out of the oven, let it stand for about 5 minutes. This is the hardest part, but it lets everything settle and makes it easier to serve.

Substitutions & Additions

Feeling inspired? Here are some ways to make this casserole even more your own!

Chicken: If you don’t have leftover chicken, a can of drained chicken or even some cooked turkey would work in a pinch.
Veggies: Love broccoli? Throw in some steamed broccoli florets along with the peas! Or how about some sautéed mushrooms?
Cheese: Feel free to mix in some cheddar cheese with the mozzarella for a different cheesy flavor. A sprinkle of Parmesan on top before baking is also delicious!
Spice: For a little heat, add a pinch of red pepper flakes to the chicken mixture.

Tips for Success

A few little secrets to make this casserole absolutely perfect every time.

Don’t Overcrowd the Tater Tots: Make sure they have space to get crispy. If your dish is a little full, you might need to adjust baking time slightly.
Cooked Chicken is Key: Make sure your chicken is fully cooked before adding it.
Prep Ahead: You can assemble the entire casserole (before baking) a day in advance. Just cover it tightly and store it in the refrigerator. You might need to add a few extra minutes to the baking time.
Crispy Top: If your tater tots aren’t quite as golden as you’d like after the suggested baking time, you can pop it under the broiler for a minute or two – just watch it carefully!

How to Store It

Leftovers are a good thing! This casserole reheats beautifully.

Once cooled, store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can gently warm it up in the microwave, or for the best texture, spread it onto a baking sheet and warm it in a 350°F (175°C) oven until heated through. The oven will help keep those tater tots crispy!

FAQs

Got questions? I’ve got answers!

Can I use fresh chicken instead of shredded? Yes! You’ll just need to cook and shred it before adding it to the mixture.
Can I make this ahead of time? Absolutely! Assemble it and refrigerate it. Add a little extra baking time.
What’s a good side dish for this casserole? A simple green salad or some steamed green beans are perfect!
