This low carb 4-ingredient chili dog casserole is the kind of easy, crowd-pleasing supper that feels right at home at potlucks, game nights, and summer get-togethers. It takes all the nostalgic flavor of a classic chili dog and turns it into a simple baked casserole with hardly any prep, making it especially handy on busy evenings when you still want something warm, filling, and fun to put on the table.
Serve this casserole with a crisp green salad, coleslaw, dill pickles, or steamed green beans to balance the rich, cheesy chili flavors. If you are feeding a mix of low carb and traditional eaters, it is also wonderful with roasted cauliflower for some and toasted hot dog buns or cornbread on the side for everyone else.
Low Carb 4-Ingredient Chili Dog Casserole
Servings: 6
Ingredients
8 beef hot dogs, sliced into bite-size pieces
2 cups no-bean chili
2 cups shredded cheddar cheese
2 tablespoons yellow mustard
Directions
1. Preheat the oven to 375°F and lightly grease a medium casserole dish.
2. Spread the chili evenly in the bottom of the casserole dish, then stir in or drizzle over the mustard so the flavor is distributed throughout.
3. Scatter the sliced hot dogs over the chili in an even layer, pressing them in slightly so they bake into the sauce.
4. Sprinkle the shredded cheddar cheese all over the top, covering the casserole from edge to edge.
5. Bake for 20 to 25 minutes, until the cheese is melted, bubbly, and lightly browned around the edges. Let it rest for 5 minutes before serving.
Variations & Tips
For picky eaters: If your family likes milder flavors, use an extra-mild chili and skip any spicy toppings. A smooth, finely shredded cheddar also melts beautifully and gives every bite that familiar cheesy hot dog flavor kids tend to love.
Make it extra hearty: If you do not mind adding a fifth ingredient, a layer of cauliflower rice under the chili makes this casserole a little more filling while still keeping it low carb. Just cook and drain the cauliflower rice first so the casserole stays thick instead of watery.
Use the right chili: A thick no-bean chili works best here because it keeps the casserole rich and scoopable. If your chili seems thin, simmer it on the stove for a few minutes first to cook off a little extra liquid.
Easy topping ideas: Once baked, you can add diced onions, chopped pickles, or a little extra mustard on top for that classic chili dog finish. Let everyone dress up their own portion at the table if you want to make dinner feel a little more fun.
