Chicken Alfredo Tater Tot Casserole
Chicken alfredo tater tot casserole puts an Italian twist on a classic casserole concept. It’s a creamy, delicious dinner that’s easy to make and easy to customize.

Back before my married days, one of my favorite dishes to make for myself was a big nine-by-13-inch pan of good, old-fashioned tater tot casserole.

Of course, being one person, that also meant I was dedicating one meal a day for the next week to eating plenty of leftovers.

I’m a sucker for leftovers, though, so while that might have driven some of you crazy, I always loved it.

When Joey and I married, I learned that he wasn’t against a tater tot casserole. It was just on his “it’s fine” list of foods, so I don’t make it too often these days. (Plus, with needing to try a new recipe every week, sometimes the old favorites take a backseat to something experimental.)

That means, when I found a recipe that is a big twist on tater tot casserole this week, you know I had to give it a try.

This comes from the blog “Inspire Spire.” You can find the original post at https://inspirespire.com/2025/07/18/chicken-alfredo-tater-tot-casserole-recipe/. I added extra seasonings and some veggies and mushrooms in my version.

Chicken Alfredo Tater Tot Casserole

Chicken alfredo tater tot casserole puts an Italian twist on a classic casserole concept. It’s a creamy, delicious dinner that’s easy to make and easy to customize.
Course: Main Course
Keyword: Alfredo sauce, baby bellas, basil, bell pepper, chicken, easy casserole, fresh mushrooms, garlic powder, mozzarella, onion, onion powder, oregano, parmesan, red pepper flakes, shredded chicken, tater tots, yellow onion

Ingredients

  • 1-2 tablespoons extra virgin olive oil
  • 1/2 medium yellow onion diced
  • 1 small bell pepper diced (any color)
  • 1/2 cup diced mushrooms I used baby bellas
  • 2 cups cooked chicken shredded
  • 15 ounces alfredo sauce
  • 2 teaspoons garlic powder
  • 2 teaspoons onion powder
  • 2 teaspoons dried parsley
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • 1/2 teaspoon red pepper flakes
  • salt and pepper to taste
  • 32 ounce bag frozen tater tots
  • 1 cup shredded mozzarella
  • 1/2 cup shredded parmesan

Instructions

  • Preheat the oven to 375 degrees. Prepare a nine-by-13-inch baking dish by spraying it with cooking spray, and set it aside.
  • Heat the olive oil in a skillet over medium heat. Add the onion, bell pepper and mushrooms, and saute until everything is cooked through.
  • Add the chicken, alfredo sauce, and seasonings to a bowl and mix it well. (If your alfredo sauce is already seasoned the way you like, you don’t need to add all the extras. Just follow your heart.)
  • Evenly spread the chicken mixture into the bottom of your prepared pan.
  • Cover the top with a single layer of tater tots, and then top evenly with the cheese.
  • Bake for 25 to 30 minutes or until the cheese is lightly browned on top.

This was creamy and delicious, and the leftovers were fabulous. I will say that if you put a little extra cheese on it like I did, you might want to layer that under the tater tots so they get nice and crispy.

I definitely made this more complicated than the original, which honestly just included the sauce, chicken, tots and cheese, but I couldn’t resist adding the extra veggies and mushrooms to the mix, and they were really good.

I think Joey secretly knew I was trying to trick him into moving tater tot casserole up on his list with this twist, but he just has too many other meals he likes a lot more. He did like it, though.

Regardless, if I’m ever going to be at home by myself for several days, I might need to opt for this new tater tot casserole to sustain me through the week.
