    Recipe ingredients

    ingredients for chicken tater tot casserole with text labels

    Ingredient notes

    • Rotisserie chicken: if you don't want to use rotisserie chicken, you can use any leftover chicken you have. You will need a total of 4 cups shredded chicken.
    • Butter: I used unsalted butter, but if you only have salted butter, that's ok to use too. Just start out with adding less salt to the base and increase the seasoning to taste.
    • Chicken broth/stock: you can use either homemade or store-bought chicken broth or stock. If you don't have chicken, you can also substitute beef or vegetable broth.
    • Onion: I prefer using a regular yellow onion for cooking, but if you don't have that you can use any kind of onion you have in your kitchen.

    Step by step photos

    1. Before you do anything else, preheat the oven to 425 degrees F (220 degrees C).

    Then, chop the onion. Set aside for now.

    2. Next, prep the rotisserie chicken. Shred the chicken into bite-sized pieces, discarding the skin and bones. Set the shredded chicken aside for now.

    3. Now, set a large pot over medium-high heat. Add the butter and allow it to melt.

    4. When the butter is melted, add in the onion and seasonings.

    5. Cook the onion, stirring frequently, for about 3 - 4 minutes, or until the onion is translucent.

    6. Now add in the frozen peas and carrots. You don't even need to thaw them, just toss them in straight from the freezer.

    7. Continue to cook the peas, carrots and onions, stirring frequently, for an additional 3 - 4 minutes, just enough to bring up the temp of the peas and carrots.

    8. Next, sprinkle in the flour. Stir the flour into the veggies and cook, stirring frequently, for about 1 minute.

    9. Now you can pour in the chicken broth. Stir the broth into the vegetables, and make sure to scrape up any stuck bits on the bottom of the pan.

    10. Turn the heat up and bring the stock to a boil. Then, reduce the heat to maintain a gentle boil. A gentle boil should look like constant small bubbles with some wisps of steam. (Check out this article on simmer vs. boil for a helpful visual.)

    11. Continue cooking the casserole base, stirring occasionally, for about 4 - 5 minutes, or until the liquid has thickened and reduced some. It should look something like this:

    12. Once the liquid has reduced, turn the stove off and remove the pot from the heat. Mix in the chicken that you shredded earlier.

    13. Finally, mix in the sour cream. Taste the casserole, and if it needs it, you can mix in a little more salt and/or black pepper.

    14. Pour the casserole mixture into a 9 x 13 inch (33 x 23 cm) casserole dish. Spread it out so the chicken is distributed evenly across the dish. It doesn't have to be perfect, just make sure the chicken isn't all piled up on one side.

    15. Now add the frozen tater tots on top. Just like for the peas and carrots, you don't have to thaw them first. Just add them on top straight from the freezer.

    16. Bake the casserole uncovered in the preheated oven for 30 - 35 minutes, or until the casserole is bubbly and the tater tots are a nice deep golden brown.

    Tips and tricks

    • Because both rotisserie chicken and store-bought broth tend to be salty, and because the amount of sodium in these products can vary, the recipe only calls for a small amount of kosher salt to start. So, just make sure to taste the casserole base before adding it to the casserole dish and adjust the seasoning if needed.
    • The recipe calls for room temperature sour cream; the reason for this is to help prevent the sour cream from curdling when it hits the hot liquid. This is also the reason why the recipe says to remove the pot from the hot burner before adding in the sour cream. I usually just measure out the sour cream before I start any of the other prep, and I find that is long enough.
    • When you first remove it from the oven, the casserole base will seem like it's not very thick. Don't worry, the casserole will thicken up significantly as it cools down.
    • For an even more indulgent casserole experience, sprinkle some shredded cheese overtop the casserole during the last 5 minutes in the oven!

    Recipe FAQs

    How do I store leftover chicken tater tot casserole?

    You can store any leftovers in the fridge, tightly covered, for 3 - 4 days. However, this 3 - 4 day guideline will only work if you cook with the chicken when it's fresh - for example, if the rotisserie chicken has already been in your fridge for 2 days when you make the casserole, it will only last for an additional 1 - 2 days.

    If you like, you can freeze the leftovers, but just be aware that because this casserole contains sour cream, the texture won't be as creamy and smooth once it's thawed and reheated.

    Can I make this casserole ahead of time?

    You can definitely prep the casserole base the day before! Once you have added the sour cream to the chicken casserole base, spread it out in the casserole dish as instructed in the recipe. Let it cool for about 10 minutes, then cover the dish and place it in the fridge.

    When you're ready to bake the casserole, remove the casserole dish from the fridge and let it sit at room temperature for about 1 hour to allow the casserole to come up close to room temperature. This is to protect the casserole dish from potentially cracking in the oven due to thermal shock.

    When you're ready to bake (and when the oven is preheated), uncover the casserole and place the frozen tater tots on top. Bake the casserole in the preheated oven, keeping in mind you may need to add more time because the casserole will not be warm like it would be when made fresh.

    If the tater tots are getting too browned before the casserole is bubbly, you can place a piece of aluminum foil overtop the casserole while it finishes baking.

    What sides go with tater tot casserole?

    This chicken tater tot casserole is pretty rich, so I would pair it with something a little lighter, such as a green salad, bean salad, or grilled veggies. It would also go great with my recipes for lemon herb roasted asparagus, microwave butternut squash, or brussels sprouts salad with cranberries and goat cheese!

    • Author: Kate
    • Prep Time: 25 minutes
    • Cook Time: 35 minutes
    • Total Time: 1 hour
    • Yield: 12 servings 1x
    • Category: main course, entree
    • Method: stove top, bake
    • Cuisine: American

    Ingredients

    Units Scale
    • 1 ½ cups (180 g) chopped onion (about 1 large onion)
    • 4 cups (500 g) shredded rotisserie chicken, skin and bones discarded (from about 1 medium rotisserie chicken) (see note 1)
    • 4 tablespoons (57 g) unsalted butter
    • 1 ½ teaspoons dried thyme
    • 1 teaspoon black pepper
    • 1 teaspoon garlic powder
    • ½ teaspoon kosher salt, or to taste (see note 2)
    • 4 tablespoons (60 g) all-purpose flour
    • 16 ounces (454 g) frozen peas & carrots
    • 2 ½ cups (590 ml) chicken broth/stock
    • 1 ¼ cups (300 g) full-fat sour cream, at room temperature (see note 3)
    • 24 ounces (680 g) frozen tater tots (about 5 ½ cups)

    Instructions

    1. Preheat the oven to 425 degrees F (220 degrees C).
    2. Chop the onion, set aside.
    3. Shred the rotisserie chicken into bite-sized pieces, discarding the skin and bones. Set aside.
    4. Set a large pot on the stove over medium-high heat. Add the butter and allow to melt.
    5. When the butter is completely melted, add the chopped onion, dried thyme, black pepper, garlic powder, and kosher salt. Cook, stirring frequently, for about 3 - 4 minutes, or until the onion is translucent.
    6. Add in the frozen peas and carrots (no need to thaw first). Continue to cook, stirring frequently, for 3 - 4 minutes.
    7. Sprinkle the flour overtop the vegetables. Stir and cook for 1 minute.
    8. Pour in the chicken broth or stock. Stir well to combine, using the wooden spoon to scrape up any bits that may have stuck to the bottom of the pot. Turn the heat up to high to bring the mixture to a boil, then reduce the heat as needed to maintain a gentle boil. Gently boil the mixture for 3 - 4 minutes, stirring occasionally, or until the broth/stock is thickened and has reduced slightly.
    9. Turn off the stove and remove the pot from the hot burner. Add in the shredded chicken and stir to combine. Stir in the sour cream. Taste the mixture and stir in more salt and/or pepper if needed.
    10. Pour the casserole mixture into a 9 x 13 inch (33 x 23 cm) oven-safe pan or casserole dish. Use the wooden spoon to spread out the ingredients evenly.
    11. Cover the top of the casserole with the frozen tater tots. Bake the casserole, uncovered, in the preheated oven for 30 - 35 minutes, or until the casserole is bubbly and the tater tots are golden brown.
    12. For a thicker consistency, let the casserole rest for 10 - 15 minutes before serving.

    Notes

    If you don’t want to use rotisserie chicken, you can use any boneless, skinless leftover chicken (white and/or dark meat) or cook your own. You will need 4 cups of cooked, shredded chicken. If you are cooking your own chicken, make sure to season it with salt and pepper!

    I used Diamond Crystal Kosher salt for this recipe, which is lighter and flakier than Morton Kosher salt. To substitute Morton Kosher salt or regular table salt, start with adding only ¼ teaspoon in with the onion and other seasonings. Then, be sure to taste the casserole mixture before adding it to the casserole dish, adding in more salt and/or pepper if needed.

    I recommend bringing the sour cream up to room temperature to help prevent the sour cream from curdling when being added to the hot liquid. It doesn't mean if you add it in cold it will necessarily curdle, but I like the extra insurance just in case! I usually just measure out the sour cream before I start any of the other prep for the recipe, and I find that is long enough.
