Best Crockpot Chili Dog Casserole

Finding a dinner that pleases the whole family and practically cooks itself can feel like an impossible task. Between juggling work, shuttling kids to activities, and trying to squeeze in some semblance of a personal life, the last thing you want is to spend your evening slaving over a hot stove.

That’s where this crockpot chili dog casserole comes to the rescue. It combines everything kids love—hot dogs, cheese, and tater tots—with the ease of a slow cooker that does all the work for you. Just layer the ingredients, set it, and forget it until dinner time rolls around.

What Kind of Hot Dogs Should I Use?

You can use any hot dogs you like for this casserole, whether that’s all-beef franks, turkey dogs, or even chicken sausages. The recipe calls for Wellshire Premium Beef Franks, but honestly, your favorite brand from the grocery store will work just fine. If you’re feeding a crowd or want lefty leftovers, grab two packages instead of one. Just slice them into bite-sized pieces before adding them to the crockpot – this helps them cook evenly and makes sure you get a bit of hot dog in every bite.

Options for Substitutions

This casserole is super forgiving and works well with whatever you have in your kitchen:

• Beef franks: Any hot dogs will work here – beef, pork, turkey, or even plant-based franks if you prefer. Just slice them the same way and you’re good to go.
• Canned chili: Feel free to use whatever chili you like best – with or without beans, turkey chili, or vegetarian chili all work fine. The amount stays the same regardless of which type you choose.
• Sharp cheddar cheese: Mild cheddar, Colby jack, or a Mexican cheese blend are all great options. You can also use pre-shredded cheese to save time, though freshly shredded melts a bit better.
• Tater tots: Frozen hash browns or even crinkle-cut fries can replace the tater tots. Just keep the same amount and cooking time.
• Sour cream and green onions: These toppings are totally optional. You can also add diced tomatoes, jalapeños, or regular onions if that’s what you have on hand.

Watch Out for These Mistakes While Cooking

The biggest mistake with this casserole is adding too much liquid from the chili, which can make your tater tots soggy instead of crispy – if your chili seems watery, drain off some of the excess liquid before layering.

Don’t skip greasing your crockpot well, because the cheese and chili can really stick to the sides and make cleanup a nightmare.

Another common error is cooking on high to save time, but this can cause the edges to dry out while the center stays cold, so stick with the low setting for the full 3.5 hours.

For extra crispy tater tots on top, try removing the crockpot lid for the last 20-30 minutes of cooking to let steam escape, and make sure your broiler is fully preheated before finishing the dish to get that perfect golden cheese on top.

What to Serve With Chili Dog Casserole?

This casserole is pretty filling on its own, but I love serving it with a simple side salad to balance out all that cheesy goodness. A basic coleslaw with a tangy vinegar dressing cuts through the richness perfectly and adds a nice crunch. If you’re feeding a crowd, corn on the cob or some roasted vegetables like green beans work great on the side. You could also set out extra toppings like diced onions, jalapeños, or shredded cheese so everyone can customize their plate the way they like it.

Storage Instructions

Store: This casserole keeps great in the fridge for up to 4 days in an airtight container. The tater tots might lose a bit of their crispiness, but the flavors get even better as they sit together. It’s one of those dishes that tastes amazing as leftovers!

Freeze: You can freeze this casserole for up to 2 months, either before or after baking. If freezing unbaked, just add an extra 15-20 minutes to the cooking time. For already cooked casserole, let it cool completely before wrapping tightly in foil and freezing in portions.

Reheat: Warm up leftovers in the oven at 350°F for about 15-20 minutes until heated through, or microwave individual portions for 2-3 minutes. If you want to crisp up those tater tots again, pop it under the broiler for a few minutes at the end.

• Calories: 3200-3600
• Protein: 110-130 g
• Fat: 190-210 g
• Carbohydrates: 240-270 g

Ingredients

For the casserole:

• 1 package beef franks (about 8-10 hot dogs, sliced into rounds)
• 12 oz sharp cheddar cheese (shredded)
• 4 cups chili (canned or homemade)
• 28 oz tater tots (frozen, I use Ore-Ida)

For Toppings (optional):

• sour cream (optional but recommended for serving)
• green onions (optional, sliced for garnish)

Step 1: Prepare Ingredients and Grease the Crockpot

• 1 package beef franks, sliced into rounds
• cooking spray or butter for greasing

Slice the beef franks into thin rounds—this increases their surface area and helps them distribute flavor throughout the casserole.

While you’re doing that, grease your crockpot with butter or cooking spray to prevent sticking.

Having everything prepped and ready will make the layering process quick and efficient.

Step 2: Combine Chili and Hot Dogs

• sliced beef franks from Step 1
• 4 cups chili

In a bowl, mix together the sliced hot dogs and chili, stirring well to distribute the franks evenly.

This prevents them from clumping together in the crockpot and ensures each bite has both chili and hot dog flavor.

I like to do this gently so the hot dogs stay intact and don’t break apart into tiny pieces.

Step 3: Layer the Casserole Base

• 14 oz frozen tater tots
• chili-hot dog mixture from Step 2
• 6 oz sharp cheddar cheese

Start building the casserole by spreading half of the frozen tater tots evenly across the bottom of the prepared crockpot.

Pour half of the chili-hot dog mixture from Step 2 over the tater tots.

Sprinkle half of the shredded cheddar cheese over this layer.

This first layer is your foundation—take a moment to ensure the tots are covered and the mixture is distributed evenly.

Step 4: Complete the Crockpot Layers

• remaining chili-hot dog mixture from Step 2
• remaining 6 oz sharp cheddar cheese
• remaining 14 oz frozen tater tots

Pour the remaining chili-hot dog mixture over the cheese layer, then sprinkle the remaining cheddar cheese over top.

Finish by layering the remaining frozen tater tots on the very top.

This creates a protective top layer that will get slightly crispy while the bottom layers stay creamy and combined.

Step 5: Cook Low and Slow

Cover the crockpot and cook on low for 3.5 hours.

The slow cooking allows the flavors to meld together and the tater tots to soften while absorbing the chili and hot dog flavors.

You can cook for slightly longer (up to 4 hours) without any problem—the crockpot maintains even, gentle heat.

Step 6: Finish with Cheese and Broil

• cooked casserole from Step 5
• additional sharp cheddar cheese for topping
• sour cream
• green onions, sliced

Once cooked, you have two finishing options depending on how you want to serve it.

For individual servings, carefully transfer portions into oven-safe bowls, top each with a generous handful of cheddar cheese, and broil on high for 5-6 minutes until the cheese is melted and bubbly.

Alternatively, for a classic chili dog presentation, spoon the casserole into toasted hot dog buns, top with cheese, and broil.

Top with sour cream and sliced green onions if desired.

I recommend the individual bowls for easier serving—the broiler gives the top a nice melted crust while keeping everything hot underneath.
