This Chili Cheese Dog Casserole takes everything you love about a chili dog and bakes it in one dish. Sliced hot dogs and chili go on the bottom, cheddar melts in the middle, and buttery biscuit pieces bake golden on top.

It uses six ingredients, takes about 40 minutes, and feeds four. Kids love it, and it’s the kind of dinner you can pull together on a busy night with things from the fridge and pantry.

Why This Casserole Works

Hot dogs are already cooked, so they only need to heat through. Canned chili does the same. That means the oven time is really about baking the biscuits, which takes 20 to 25 minutes.

Cutting the biscuits into quarters is the key step. Small pieces bake faster and more evenly than whole biscuits. The bottoms soak up a little chili while the tops turn crisp and golden. A brush of melted butter and a sprinkle of garlic powder make them taste like garlic bread.

Ingredients and Easy Swaps

• Hot dogs: 6 hot dogs, sliced into 1 inch pieces. All-beef franks have the best flavor. Turkey dogs or smoked sausage also work.
• Chili: One 15 ounce can, with or without beans. Leftover homemade chili is even better. Use about 2 cups.
• Cheddar cheese: 1 cup shredded. Sharp cheddar gives the most flavor. Colby Jack or a Mexican blend are good swaps.
• Refrigerated biscuit dough: One can of 8 biscuits. Regular or buttermilk biscuits both work. Flaky layered biscuits get extra crisp.
• Melted butter: 1 tablespoon for brushing the biscuits.
• Garlic powder: ½ teaspoon for the biscuit topping.

How to Make It at a Glance

1. Heat the oven to 375°F and grease a baking dish.
2. Mix the chili and sliced hot dogs, then spread them in the dish.
3. Sprinkle the shredded cheddar over the chili mixture.
4. Cut the biscuits into quarters and scatter them over the top.
5. Brush the biscuits with melted butter and sprinkle with garlic powder.
6. Bake for 20 to 25 minutes, until the biscuits are golden and the chili is bubbling.

Common Mistakes to Avoid

Using too big a dish. An 8×8 or 9×9 inch dish keeps the chili layer deep enough to stay saucy. In a 9×13, the chili spreads thin and can dry out.

Crowding the biscuits. Leave small gaps between the pieces. Steam needs to escape so the biscuits cook all the way through instead of turning gummy underneath.

Pulling it too soon. Golden tops don’t always mean the centers are done. Lift a piece in the middle with a fork. If it looks doughy, give it 3 to 5 more minutes.

Starting with cold chili straight from the fridge. Leftover chili should be warmed a bit first so the center heats through by the time the biscuits are done.

Variations

• Cornbread top: Swap the biscuits for a box of cornbread mix spread over the chili. Bake according to the box.
• Add onions: Stir ½ cup diced onion into the chili for that classic chili dog stand flavor.
• Spicy: Use hot chili and add sliced jalapeños under the cheese.
• Tater tot top: Replace the biscuits with frozen tater tots and bake until crisp.

What to Serve With It

Keep the sides simple. Coleslaw, a crunchy green salad, or raw veggies with ranch balance out the rich casserole. Corn on the cob or baked beans fit the cookout theme. Set out toppings like diced onion, mustard, sour cream, and pickles so everyone can dress their own plate.

Make Ahead, Storage, and Reheating

Make ahead: Mix the chili and hot dogs and keep them covered in the fridge for up to a day. Add the cheese and biscuits right before baking. Raw biscuit dough gets soggy if it sits on the chili too long.

Storage: Cover leftovers and refrigerate for up to 3 days.

Reheating: Warm individual portions in the microwave until steaming hot. To keep the biscuits crisp, reheat in a 350°F oven for 10 to 15 minutes.

FAQ

Can I use homemade biscuit dough?
Yes. Drop spoonfuls of your favorite biscuit dough over the chili and bake until golden and cooked through.

Do I need to cook the hot dogs first?
No. Hot dogs are fully cooked. They heat through in the oven along with the chili.

Can I double it?
Yes. Double everything and bake in a 9×13 inch dish. Add about 5 minutes to the bake time.

Can I freeze it?
The chili and hot dog base freezes well for up to 3 months. The baked biscuits get soft after freezing, so it’s best to add fresh biscuits when you bake.

Tips for the Best Results

• Slice the hot dogs into even 1 inch pieces so they heat through at the same rate.
• Bake on the middle rack so the biscuits brown on top without burning on the bottom.
• Let the casserole sit for 5 minutes before serving so the chili thickens.

Kid-Friendly Swaps

Choose a mild chili with no beans if your kids are picky. Mild cheddar or American cheese melts creamy and smooth. Kids can help by placing the biscuit pieces on top and brushing on the butter. Serve with ketchup and mustard on the side so everyone can top their own plate.

Budget Tips

Hot dogs, canned chili, and refrigerated biscuits are some of the most affordable foods in the store. Store brands work just as well here. If you make a big pot of homemade chili, freeze 2 cup portions so this casserole is ready to go on a busy night.
