Step‑by‑Step Instructions for Keto Chili Dog Casserole Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, grab a 9×13 inch casserole dish and coat it with a generous layer of nonstick cooking spray to ensure easy serving later on. This foundational step sets the stage for our hearty Keto Chili Dog Casserole.
Step 2: Make the Chili Base
In a medium saucepan over medium heat, combine your browned ground chuck with petite diced tomatoes, water, and all the fragrant dry seasonings – chili powder, ground cumin, garlic powder, onion powder, and dried oregano. Stir well, then bring the mixture to a gentle boil. Reduce the heat and let it simmer for 8-10 minutes, or until the chili thickens nicely, enveloping your kitchen with delicious aromas.
Step 3: Layer the Chili
Once your chili mixture is ready, carefully spoon about ½ cup of it into the bottom of your prepared casserole dish. Spread it evenly to create a flavorful base for the hot dogs that will soon follow. This layer of chili will infuse the casserole with flavor, ensuring each bite of the Keto Chili Dog Casserole is packed with taste.
Step 4: Roll the Hot Dogs
Taking your hot dogs, individually roll each one into a low-carb tortilla or wrap, tucking the ends in tightly so they stay securely rolled. Place the rolled hot dogs seam-side down into the casserole dish atop the chili layer you’ve just spread. This step keeps the hot dogs snug and helps the flavors meld together as the casserole bakes.
Step 5: Add the Remaining Chili and Cheese
Pour the remaining chili mixture evenly over the wrapped hot dogs, ensuring they are well-covered. Then, sprinkle a generous amount of shredded cheddar cheese on top, allowing it to melt into a bubbly, golden topping. This rich layer enhances the indulgent nature of the Keto Chili Dog Casserole and promises a delightful, cheesy finish.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 30-35 minutes. Keep an eye on it as it cooks; you’ll know it’s ready when the cheese is bubbly and golden brown, creating a mouthwatering, inviting appearance. Allow the casserole to cool slightly before slicing, which helps it firm up for easy serving.
Step 7: Serve and Savor
Once cooled, slice your Keto Chili Dog Casserole into portions and serve warm. Consider adding keto-friendly toppings like diced onions, avocado, or a drizzle of mustard for an extra kick of flavor. This comforting dish not only whisks you away to childhood memories but also fits beautifully into your low-carb lifestyle!

Make Ahead Options
These Keto Chili Dog Casserole recipe components are perfect for meal prep, allowing you to save precious time on busy nights. You can prepare the chili base up to 24 hours in advance; just store it in an airtight container in the refrigerator to maintain its rich flavors. Additionally, you can roll the hot dogs in the low-carb tortillas and assemble the casserole without baking, keeping it wrapped tightly in the fridge for up to 3 days. When you’re ready to serve, simply pour the chili over the hot dogs, top with cheese, and bake directly from the fridge, adding about 5-10 extra minutes to the baking time for a delicious, hassle-free meal!
How to Store and Freeze Keto Chili Dog Casserole
Fridge: Store leftovers in an airtight container for up to 4 days. Ensure the casserole is completely cooled before sealing to maintain freshness.
Freezer: You can freeze Keto Chili Dog Casserole for up to 3 months. Slice it into portions, wrap them tightly in foil, and place them in a freezer-safe bag.
Reheating: For the best results, reheat in the oven at 350°F (175°C) for about 20 minutes or until heated through. Microwaving is also an option; just cover with a microwave-safe lid and heat in short intervals until warmed.
Serving Tip: Adding a splash of water before reheating can help maintain moisture and enhance the creamy texture of the melted cheese.

Keto Chili Dog Casserole Recipe FAQs
What is the best way to select ground chuck for the chili base?
Absolutely! When selecting ground chuck, look for a bright red color with some marbling, indicating good fat content. Aim for beef that’s freshly ground for optimum flavor. Avoid any packages with dark spots or a sour smell, as these are signs of spoilage. If you’re looking for a leaner option, ground turkey or chicken is an excellent substitute, just keep in mind that the flavor profile will be slightly different.
How should I store leftovers from the Keto Chili Dog Casserole?
Very good question! Store your leftovers in an airtight container in the fridge for up to 4 days. Make sure it’s completely cooled before sealing to help keep it fresh and prevent moisture build-up. If you’re meal prepping, this dish is perfect; it holds up well and tastes delicious even the next day!
Can I freeze the Keto Chili Dog Casserole?
Yes! You can freeze leftovers for up to 3 months. For best results, slice the casserole into portions and wrap each piece tightly in aluminum foil, then place them in a freezer-safe bag. When you’re ready to enjoy, you can reheat it directly from frozen—just add a few extra minutes to the cooking time for even heating.
What should I do if my chili mixture is too watery?
If you find your chili is a bit thin, don’t worry! Just continue to simmer it on medium heat while stirring. This will allow some moisture to evaporate and thicken the chili. Typically, letting it simmer for an additional 5 to 10 minutes does the trick. For an even thicker consistency, add a small amount of grated cheese into the chili, as it will melt and help bind the ingredients together.
Are there any dietary considerations I should be aware of?
It’s always good to check! The Keto Chili Dog Casserole is gluten-free if you use gluten-free tortillas. However, make sure to read ingredient labels for allergens. If you have a sodium-sensitive pet, note that seasonings and hot dogs can be high in sodium, so those shouldn’t be shared. For a lower-carb option, opt for turkey or chicken hot dogs, and always choose brands that are free from fillers or sugars.
How do I know if my ingredients are fresh enough for the casserole?
Great question! For ground meat, always check the sell-by date and look for a bright red color. Petite diced tomatoes should be in cans without any dents or rust, and the expiration dates should be checked. Spices should be aromatic; if they lack scent, they’re likely past their prime and may not contribute the flavor you’re after. A bit of attention goes a long way in making a tasty casserole!
