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.

Nutrition Information for Keto Chili Dog Casserole:

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.
  • Want to lower the carbs? Look for the lowest carb hot dogs and use fewer onions.

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. I have made this twice now only thing I tweaked was left onions out hurt my husband stomach and I chop my hot dogs up to make it easier to scoop and eat. But I love it

  2. Made this last night and it was great! Thank you. I want to share the recipe with busy mom/not keto person…how many cans of beanless chili did you used to use? Thanks.

    1. I made my chili from the recipe below. I’m not sure how many cans it equals. But if I were using canned chili, I would buy 2 cans and just use however much looked right.

  3. Jim O'Brien says:

    Top notch. I added some coriander, cilantro, stevia liquid for the sweetener, and 2 chiles de arbol to spice it up more. I made it in a porcelain bread pan in two layers because the hot dog pack only held five hot dogs. Very tasty! Thanks for the recipe.

  4. My husfriend(long time boyfriend) and I love this recipe! It’s in my weekly rotation for low carb dinners. I do like to add about a 1/2 tsp of red pepper flakes to give it a slight kick! Then top with sour cream! So delish!!

  5. Julie Sullivan says:

    Going to make this tonight. However we have some homemade chili beans (so good!) that have been in our freezer for some time and will use those for now and then do the low carb version next time. As soon as I told my husband about this recipe, he was fully on board with making it and has been looking forward to it ever since then. I am really interested to see how it is going to turn out. Looks delicious!

    1. Thanks, hope you like it! (I always keep chili beans on hand to serve to the kids!)

  6. 6 months pist op VSG. I was so excited to cook this tonight and it did not let me or my family down. Seriously sooo good!

  7. family loved this one, thanks for posting

  8. This was so delicious!! #KidApproved I left the bell pepper out, used Truvia, ended up putting 1 tbs Worcestershire sauce and 2 tbs tomato paste both on accident and it still turned out amazing! This will definitely be a fave on our list!!

  9. Made this for dinner. The hot dog chili sauce is really good. I used Swerve for the sweetener instead of sugar. My husband loved it. Definitely going into regular circulation.

  10. Made this tonight! Used half the water, didn’t drain the hamburger grease (on the keto diet). Used the chili mix instead of the spices listed. Absolutely Delish! My husband also enjoyed it, and he isn’t on a diet! Calculated with the ingredients I used… 7net carbs per serving. 4 servings total. 2 hotdogs per serving.

  11. Gwen Frazier says:

    Great idea! Being from Texas this needed a LOT more chili powder, so I would definitely say to taste it after it has simmered a little. I left out the green pepper too to cut down on carbs. Really good recipe

  12. I have made this several times. My husband and I love it! Thanks!

  13. My husband and I are making the low-carb chili cheese hotdog bake tonight and I just want to say this recipe is amazing and I can’t wait to see more recipes from Because I am a type two diabetic

  14. Stephanie says:

    I live a chili dog and just cut carbs/sugar from my diet. Can’t wait to try it. One suggestion that is a little easier than using the food processor to make the chili finer. But the ground beef in a bowl and cover it with water for about 20 minutes. I do it all the time and the chili texture is spot on. Thanks for sharing!

    1. Hi, could you elaborate on this? Soak the cooked ground beef in water? Then leave for 20 mins and then drain? Or the raw beef? How does this make the beef finer? Thanks!

      1. In case she doesn’t answer, (I’m just guessing here) she is probably soaking it raw, draining, and then cooking. I would think the water would promote a finer/smaller ground beef. (Just my theory – nothing to back it up.)

  15. LOVE this recipe! Going Keto left me hungering for some old “grab in a dash” standbys, i.e. Dairy Queen Chili Cheese dog. I have to tell you THIS IS FAR SUPERIOR and has whittled that memory away! Thank you!

    1. So happy to hear that – It’s a favorite of mine too!

  16. What’s the nutritional value? I can’t find it in fitness pal and when you enter the ingredients it comes out hella high carbs

  17. Christina says:

    This was amazing and really brought me back to my childhood and made me nostalgic. Easy to hide veggies too and my 10 YO son loved it. Great idea!

  18. I tried this recipe today. My family love this low carb chili dog, perfect for gathering.

  19. The chili is AMAZING. By far the best “home-made” – the ingredient combinations are perfect. Next time I am going to triple the recipe and make a meal of the chili itself. All around outstanding recipe. Thank you!

  20. It was so good! We doubled the recipe, so slightly more carbs, but the pan is empty and I staying with my carb count! Will definitely make again!
