This easy Keto Taco Casserole recipe has only 5 ingredients and a 5 minute prep time. It is a lifesaver on busy weeknights. Ground meat combined with a creamy salsa sauce and plenty of cheese makes the perfect base for your favorite toppings.
I love anything Mexican, Southwest, Tex-Mex, whatever you want to call it. Those vibrant flavors are always welcome after a few nights of baked chicken or other simple fares. I decided to take a classic taco casserole with refried beans and corn chips and make it keto friendly. My taco casserole recipe is great for a keto or low carb diet. It is also gluten-free, grain-free, and Trim Healthy Mama friendly.
My children really enjoyed this easy low carb taco casserole recipe. The ten-year-old boy had thirds. A couple of the children put it into taco shells and ate it that way but most of us topped it with sour cream and avocado and dug right in.
Since I first made this keto taco casserole we've had it dozens of times and a friend even made it for us after my 5th baby was born! Everyone who has tried it loves it whether they are on a keto diet or not.
Ingredients Needed
Ground Meat - I typically use ground turkey but you can definitely make this into a keto ground beef casserole by subbing in browned ground beef. Shredded chicken works great as well.
Salsa - make sure to choose one without added sugar. If it has a lot of liquid drain it before adding it to the casserole.
Cottage Cheese - this is my secret ingredient for added protein and a creamy texture. I promise you cannot taste it in the finished low carb casserole.
Cheddar Cheese - you can use any type of shredded cheese that goes well with Mexican food. A Colby jack Mexican cheese blend is the one we use most often if we are out of cheddar.
Taco Seasoning - I make my own keto taco seasoning to avoid added ingredients like cornstarch and sugar. Homemade taco seasoning is cheaper and tastes better than those packets you see in the grocery store. My seasoning combines onion powder, garlic powder, minced dried garlic, minced dried onion, paprika, cumin, chili powder, oregano, crushed red pepper flakes, salt, and pepper.
How to make Keto Taco Casserole
The best part about this keto taco bake recipe is that the entire hands-on time is only about 5 minutes and it has only 5 ingredients. I make my low carb Mexican casserole with ground turkey but you can sub in any meat of your choice or sauteed vegetables for a vegetarian entree.
First Step: Stir together the salsa, cottage cheese, and cheddar cheese.
Second Step: Spray a baking dish with olive oil or cooking spray. Brown the meat in the oven in the casserole dish. Next, break it up and drain the cooking liquid. I chop it right in the casserole dish with a potato masher.
Expert Tip: Yes, I just cook the ground turkey right in the casserole dish in the oven! This saves on having a frying pan to wash by cooking the meat in the oven instead of browning it in a frying pan.
Third Step: Cover ground turkey or ground beef mixture with the creamy cottage cheese sauce. I promise the end result will not taste like cottage cheese!
Expert Tip: if you really don't want to use cottage cheese you can sub in half softened cream cheese and half sour cream.
Fourth Step: Next, sprinkle the keto taco casserole with cheese. Any tip of shredded cheese will work, cheddar, Monterey Jack, or a blend.
Fifth Step: Finally, bake the low carb taco casserole until hot and bubbly. Since you already cooked the meat as soon as the casserole is hot you can serve it.
Expert Tip: For the best golden brown cheese on top broil the casserole for 2-3 minutes right before serving. Make sure to keep an eye on it because it can go from golden brown to burned pretty quickly.
Tips
My casserole was a little juicy but I didn't take the time to really drain the meat properly since ground turkey isn't greasy. We didn't mind. And the few portions of leftovers we had stayed moist. There is nothing worse than dried-out leftovers. We make ground turkey tacos all the time. My guests normally don't even realize it is ground turkey vs ground beef.
If you drain the meat thoroughly AND drain the excess liquid from your salsa your casserole will not be so moist.
Variations
Peppers & Onions - Slice a pepper and an onion and put them right into the casserole dish with the raw meat. They will cook and soften along with the meat.
Green Chiles - Replace the salsa with a can of green chiles and diced tomatoes, such as Rotel.
Crushed Red Pepper - Mix some red pepper into the salsa mixture for a bit of heat.
Jalapenos - Place thinly sliced jalapeno peppers on top of the shredded cheese before baking.
What to serve with a Taco Casserole
Top with your favorite taco toppings and serve!
Sour Cream - we use sour cream by the bucket in my house. A Costco-sized container only lasts about a week.
Avocados - you can either just serve sliced avocados or make keto guacamole. We always have avocados on the counter in various stages of ripening. They get eaten as quickly as they ripen in my house.
Diced Tomatoes - if you love tomatoes feel free to add a few fresh ones on top of this. Or top with some fresh keto salsa.
Lettuce - you can serve this with shredded lettuce under or on top.
Other Salad Veggies - chopped bell pepper and green onions also go well with this.
Cilantro - if you are a cilantro fan sprinkling some of the top adds color and flavor. I love the fresh taste that cilantro adds to Mexican dishes and use it generously!
Keto Tortilla Chips - serve this as a dip with some low carb chips or pork rinds.
Cauliflower Rice - make a taco bowl and serve this keto taco casserole on top of a bed of cauliflower rice. Either fresh or frozen cauliflower rice both work well!
Black Olives - thinly sliced black olives are great with this recipe.
Common Questions
Is Cottage Cheese Low Carb or Keto?
Yes. You can use cottage cheese while eating low carb or keto. Eating an entire tub of cottage cheese is not keto but using 2 cups divided by 6 servings is totally fine. Higher fat cottage cheese has lower carbs so you can choose a cottage cheese that is full fat for a keto casserole.
I used Nancy's Organic Lowfat Cottage Cheese in this keto Mexican casserole. One of the reasons I love using cottage cheese is because it is high in protein. This one is also naturally gluten free and contains live probiotics.
In my house, I am the only one who eats cottage cheese plain but the rest of my family eats it in low carb recipes such as casseroles, cottage cheese cheesecake, and other baked goods. I just don't mention the cottage cheese until after they've tried this keto taco casserole recipe and liked it.

Can you have sour cream on keto?
Yes, sour cream is definitely keto friendly. It has only 0.3g of net carbs per tablespoon. Try to buy one without additives and fillers.
Can I Make This in a Slow Cooker or Instant Pot?
Yes. Either will work! And make sure to check out my recipe for crock pot keto chicken tacos.
Slow Cooker - To make in a crock pot simply cook the meat, drain the liquid, and then add the other ingredients.
Pressure Cooker - For an instant pot recipe, you can brown the meat on the saute setting, drain any cooking liquid, and then add the other ingredients.
How do I store leftovers?
Store any leftovers in an airtight container in the fridge. I will put lunch-sized portions in small glass containers and then just reheat in the microwave when I meal prep.

Keto Taco Casserole
Ingredients
- 1.5 - 2 lb ground turkey or beef
- 2 tablespoon taco seasoning
- 1 cup salsa
- 16 oz cottage cheese
- 8 oz shredded cheddar cheese
Instructions
- Preheat oven to 400.

- Meanwhile, mix together the cottage cheese, salsa, and 1 cup of the cheese. Set aside.
- Remove the casserole dish from the oven and carefully drain the cooking liquid from the meat. Break up the meat into small pieces. A potato masher works great for this. Spread the cottage cheese and salsa mixture on top of the meat. Sprinkle the remaining cheese on top.

Sue Edwards says
Sounds delicious!
Sara says
This looks great! Nutrition question....there can't really be 81g of protein per serving, right?? Please let me know. Thanks!
Taryn says
I just double-checked the nutrition facts and there was a discrepancy. It should be 45g of protein.
Sue McNeil says
I made this using chicken and OMG it was delicious. I served it with lettuce, tomatoes and extra salsa with keto tortilla chips. My 93 year old mother cleaned her plate. My brother in law went for seconds and used a low carb wrap and cleaned up the leftovers . My sister and I loved it and will definitely make it again .. beef next time. Thank you so much for this recipe.
Alexis says
Exactly how much is a serving size?
Taryn says
1/6th of the casserole. I just eye it up and cut through the cheese and then scoop.
KAS says
Too many advertisements and pages to print for just one recipe!
Taryn says
Did you click the print button? It goes to a one page printable view without advertisements. It is at the top of the page and within the recipe card.
Kim says
Can I add rice and beans into the whole mixture before baking to make an XO for my whole family and me (nursing mama)
Della says
Confused old lady. It looks like you used more than 8 oz cheddar cheese. The instructions have cheese added twice....mixed with the cottage cheese/salsa.....then again spread on top. The recipe looks great! Easy.
Taryn says
8 ounces of cheese is equal to 2-2.5 cups. That is what I used, half mixed in to the meat and the other half on top. I shred an 8 ounce block.
Charla Davis says
Awesome! Can this be frozen for later?
Taryn says
Yes, I've frozen individual servings to reheat for lunch. It freezes pretty well.
Mikey says
Thank You for the receipe. Very easy & quick to prepare & in oven as I write this. I know I will love it as I love all the ingredients.
Rachel says
I have made this recipe so many times since discovering it. We aren't keto anymore so today we are eating it with tortilla chips. Makes a great salad topping or over rice bowls too. Delish and so so easy!
Kimberly Lee says
Hi Taryn, Thank you so much for an excellent recipe! Often I have found keto casseroles to be more like a dip and not a casserole and this was far from that. Followed exactly and I cut the servings in half and served over a southwestern salad. So made for an amazing keto taco salad!! Thank you again for sharing!
Cana says
I made this last week and my family loved it, even my pickiest kid!
Angie says
I made this for the first time for a friend doing keto! I had a very large amount of ground chicken taco meat, and used 2% cottage cheese. Also added some riced cauliflower. It smelled amazy and they said it was tasty!!
Charlene says
Could I replace the cottage cheese with plain Greek yogurt? Thanks!
Taryn says
I would be afraid it would separate. A better sub would be softened cream cheese.
Soraya says
Loved it.
sherry says
This was amazing! We had regular homemade tacos the night before and I overestimated how much the family would eat so I had a ton of taco meat left over. I needed a THM recipe to use up my 2+ pounds of leftover taco meat. Your recipe was perfect to disguise my leftovers.
Adam Suranyi says
When using ground beef, the values are huge. I made this mistake a few too many times before doing the math.
Using 2.25 lbs of 80/20 ground beef, this is what I come up with for 6 servings.

Taryn says
Those numbers look off to me. Are you using 4% fat cottage cheese? Is your nutrition calculator assuming the taco seasoning has flour or cornstarch? The carbs shouldn't change by switching it to beef.
Nicolas Labowitz says
I love this!! Today ai made it for the first time and it was great, but I'm not sure if I did good on the quantities. Could you share with me the amounts in measures??. Thanks a lot!!
Nicolas Labowitz says
I mea in metric system. Thanks a lot!
Taryn says
I just added the conversions - glad you liked it!
Nicki says
I made a recipe similar to this before and I just wanted to throw in my two cents on the cream cheese question.. you can mix the cream cheese with the ground beef while its still warm and it will be fine. The only way you really have to worry about curdling is when say you have an almost at boiling soup etc and you throw in an ice cold stick of cream cheese into it.
Probably not for people on but Keto there is a Hamburger Helper boxed dinner called Cheesy Enchilada that kinda comes out tasting like this but it has rice. When I was younger I would buy the double boxes ,make it up and throw in an extra 1 to 2 cups of rice depending on how far I needed to stretch the meal. I know not the healthiest but if you are having a poor week or need something hearty & yummy it was a good goto.
Jennifer says
If you are doing full Keto, watch the taco seasoning. Store bought packets can have fillers that increase the total carbs in this recipe drastically. I used a homemade spice blend and it turned out wonderfully and at only 6 carbs a serving fits into my husband's carb limit. There are a lot of recipes online for taco seasoning. I had to find the closest to zero carbs as possible for my hubby. This recipe is going into our rotation for sure!
Taryn says
Very true! I make my own. Here is my recipe: https://joyfilledeats.com/how-to-make-taco-meat-taco-seasoning/

I just made this last night. We all loved it! definintely using this again.
