Low Carb Chili Dog Casserole

Chili Dogs are the Ultimate Summer food!

Hot dogs (and burgers, of course) really are the ultimate summer cook-out food.  My kids request them for dinner all the time.

We’ve been grilling outside a lot lately. With Labor Day around the corner, I figured it was time for me to come up with a way the entire family could enjoy chili dogs again.  (Hubby and I are eating low carb right now, so a traditional chili dog in a bun is off the table.)

In the past, I would buy canned chili for our chili dogs, but even the canned bean-less chili’s have quite a few carbs in them, so it’s better to make my own version of a low carb chili.

Ok, so the big question I get is: How many carbs are in this low-carb chili dog casserole?

The Answer?

Well, unfortunately, I can’t give you hard numbers as it will vary a tiny bit based on the ingredients you choose to use.

But… If you make it exactly as the recipe below it comes to 498 calories, 8 net carbs, 37 grams of fat, 33 grams of protein, and 5 grams of sugar. (Per serving – 6 servings in the dish)

  • Want to lower the fat count? Use less cheese.

Ingredients:

Want to give this chili dog casserole a try? Just copy and paste the ingredients listed below to your grocery list. (ingredients at a glance grab the printable recipe card at the bottom of the post.)

  • Beef Hot Dogs | Different brands have different carb amounts, just check the packaging.
  • Cheddar cheese | save carbs by shredding your own. Monterey /Colby Jack blend also works great.
  • Ground beef | Leaner the better for this recipe.
  • Tomato sauce and tomato paste
  • Garlic Cloves | Minced garlic from the jar works too. 1/2 tsp of minced garlic equals one fresh clove.
  • Bell pepper | Whatever color you prefer- green has the lowest amount of carbs
  • Onion | Yellow onion would be the first choice for this recipe, but white will work too.
  • Chili powder, ground cumin and celery salt
  • Worcestershire sauce
  • Sugar substitute | Many readers have opted to leave this out, but I think it adds an authentic flavor to the chilidog sauce. Sugar is often used to cut the acidity of the tomatoes and using a small amount helps balance the flavors to create a richer overall chili.

How to Make this Low Carb Chili Dog Casserole

The reason this recipe is so yummy and low carb too is partly because of the homemade chili dog sauce.

You could make this chili dog bake with commercially prepared chili dog sauce. It would taste great too, but that sauce from the can has quite a few more carbs than my recipe does. Making your own chili is slightly more work, but oh, so rewarding!  

(Scroll to the bottom for a printable recipe card.)

  1. To make this Keto Chili Dog Casserole, start by browning the meat with the peppers, onions, and garlic.  Add the spices, tomato sauce, paste, and water. Simmer for about 30 minutes. 
  2. Once the chili is done, an optional step, but something I recommend, is to use an immersion blender or food processor to chop the chili into small pieces, as authentic chili sauce would be.
  3. Assemble the casserole by spreading prewarmed/room temp hot dogs flat on the bottom of a 7 x 9 casserole dish. (if your hot dogs come straight from the fridge, you may need to increase the baking time.)
  4. Cover the dogs with chili.  (You should have enough chili to reserve a bit if you have anyone eating regular hot dogs and wants chili on top. Otherwise, use it all.)  Spread 1 cup of cheese over chili and top with remaining onion.
  5. Bake at 400 F for about 15 to 20 minutes or until hot and bubbly!

Can you make this Low Carb Chili Dog Casserole in the Slow Cooker?

Yes! You can make the chili dog casserole in the crockpot, however, the instruction will be a bit different.

  1. Start by browning the ground beef with the garlic, onion, and peppers in a skillet on the stovetop.
  2. Once browned, add the ground beef to the slow cooker. Add the rest of the spices, plus tomato sauce, paste, and water. Use an immersion blender to chop the sauce into fine pieces.
  3. Top with hot dogs and cheese and cook on high for 2 hours or low for 4.
  4. Stir before serving and top with additional cheese and onions if desired.

How Long Will this Chili Dog Casserole Last in the Fridge?

Once cooked, this casserole will last 3 to 4 days in the fridge

Can I Freeze this Chili Dog Casserole

Yes, you can definitely freeze this keto Chili Dog Casserole.  There are 3 ways to freeze it.

  1.  Let chili cool significantly, package it up in 1 to 2 servings into a freezer bag, taking care to remove all the air from the bag.  Then when ready to eat, just microwave it on medium power until defrosted. Transfer to a bowl and continue to heat until warmed through.
  2. Create the casserole as directed.  Sto before baking.  Wrap tightly with foil and freeze.  When ready to eat, remove from the freezer and let thaw in the fridge for 24 hours.  Bake in the oven for about 30 minutes until everything is hot and bubbly.
  3. The 3rd way, (recommended) is to prepare the recipe up to assembling the casserole. (So just cook the chili.) Let chili cool significantly, package it up into a freezer bag, taking care to remove all the air and freeze.
  4. When ready to make the casserole, put the frozen bag in the fridge in the morning to defrost.  Then when ready to cook, place chili in the microwave to finish warming.  Assemble the casserole and bake as directed in the recipe

Can you make Chili Dog Casserole ahead?

Yes, parts of this casserole can definitely be made ahead of time. The chili is what takes the most amount of time to make and can be made a few days ahead and stored in the fridge. Then just put the casserole together before you are ready to bake.

Chili Dog Casserole Variations

This is a great casserole for the family as everyone loves chili dogs and won’t miss the buns. However, you can serve it so many ways to satisfy everyone in the family.

  • Hungry teenage boys, that eat you out of the house? Serve it over hot dog buns and add chili beans!
  • If you’re gluten-free instead of low carb, this would be awesome with corn chips.  Just cut the hot dogs into smaller slices and scoop the chili, franks, and cheese up with the chips.
  • Or spoon the chili dog bake right into a snack-size bag of chips! Like these walking frito pies.)

  1. Delicious! Lots of flavor. Loved the homemade chili. Great topped with sour cream.

  2. This was so good! Husband loved it. I toasted keto buns and served over that. Awesome!

  3. Loved it! very good

  4. Stephanie says:

    My family of 5 loves this recipe and it’s great as left overs as well!

  5. We love this recipe with a couple of changes. No onions since my kids freak out over them, and I cut the dogs into small pieces and toss them in with the chili to simmer before throwing it all in the oven. They soak up a lot of liquid that way and get nice and plump. The flavor is great!

  6. Great idea! I left out the green pepper to lower the carb count and added a lot more chili powder. Taste before you decide.

  7. Fantastic! I did make a few changes….didn’t have celery salt, omitted sugar and was very heavy hand d on spices because I cook without measuring. Absolutely delicious and will make it many times!!!

  8. Delicious! The chili recipe made a little extra, but it was so good that no one in my family really minded. We all are looking forward to making it again

  9. Amazing! I added fresh jalapeño slices to my bowl right at serving, gave it that extra kick I love on a chili dog. I used chiapetti beef hot dogs. This will be on the regular rotation, only change will be to cut the hot dog quarters in half so I don’t have to do it when I eat it 🙂

  10. Christine says:

    This is really good for those times when you for whatever reason against your better judgement are just craving a chili dog. I am not a big hotdog fan at all but this came out so good. Do yourself an favor and follow the suggestion to shove the chili mixture into a food processor. It does indeed come out similar consistency to the canned hotdog chili.

  11. Amazing! The chili flavor was on point as well

  12. I made this, but fried the hot dogs for a few minutes in my air fryer while making the “chili”. I then sliced the hot dogs into bowls and topped with chili, cheese, and onions. SO GOOD!! (I put Dijon mustard on mine because that’s how I eat my chili dogs)

  13. This recipe was a complete hit! I used Jenny-o turkey dogs to decrease the amount of carbs. My 4 year old son does NOT like hot dogs or any food that doesnt have a smooth texture, but he LOVED this dish so much he had 2 servings (4 yr old servings).

  14. We LOVED this. Rather than cut the dogs simply in half I chopped them so you can get a lesser serving if desired. This way you don’t have to have that many dogs to make it work. Bar S smoked sausages work very well also! I used up leftover BBQ dogs for this and it was great. I added a lot more worcheshire sauce (3x as much). I also added a bit more stevia to sweeten the chili. I added chopped celery -3 stalks instead of the celery salt, and chopped green peppers for more veggies! Reheats well!

  15. Used 3/4 lb beef and dbl the tomato paste. so good!!!!

  16. This turned out AMAZING. It’s definitely going to be one of my top new recipes and it’s been a hit with everyone that has tried it so far!

  17. Have now made this twice. It is great!

  18. Love this recipe – really good!!!

  19. This was so good! A little watery; I’m going to reduce each liquid by 1/4 cup next time. I’m also going to try chopping up the hot dogs instead of halving them.

    May also omit sugar next time.

    1. I recommend not reducing the liquids. just simmer it a bit longer with the lid off. The liquids will cook down more and the chili will have an even better flavor.

  20. Kendra@aol.com says:

    Very Good. Tasty chili even by itself

  21. This was so good and will be making It again. wouldn’t change a thing.

  22. We really liked it. I put in 8×8 pan and left hot dogs whole. Used immersion mixer. We had on low carb wraps. Super easy. Will make again.

  23. THIS IS SOOO GOODDDDDD!!! I used 1 whole onion in the chili and the whole little can of tomato paste because I hate just using a spoonful. Soo good.

  24. Really good! Would definitely recommend pureeing it a bit for that true chili dog texture. It was so good that way! Kid approved!
