The Best Keto Taco Casserole


Are you tired of same-ol’ tacos that always seem to fall apart and make a mess? Well, fear not, my friends, because the solution to all your taco troubles has arrived in this beautiful form- a taco casserole!

This taco casserole has all the delicious flavors of a traditional taco but is baked into a casserole, so it’s super easy to make and even easier to eat. If the article’s title has yet to reveal the secret, this recipe is keto-friendly so that you can reach for seconds even on a low-carb or keto diet. So, grab your oven mitts and prepare to spice up your dinner routine with this tasty keto taco casserole.

The Ingredients You’ll Need:


Although the spices listed in the ingredients are many, don’t be alarmed. They are on the list because they create our preferred taco seasoning customized to our flavor profile. The good news is that most of these spices you should already have in your kitchen cabinet. We advocate for making your own special blend especially if you don’t have a prepackaged sachet of taco seasoning handy. If you are like us and need control, doing this makes even more sense. However, if you don’t have this problem or want to avoid purchasing a bunch of individual seasonings, go ahead and buy a pre-packaged mix. Just be sure to check the label before you put anything in your cart, as some may include hidden starch and carbs.

Either way, store-bought or homemade, you need some ‘taco’ seasoning. This is a must-have and gives the authentic taco flavor to the casserole. 

Tip: If you decide to use a store-bought taco seasoning, you can omit the spices listed in the recipe card and use about a 1/2 cup of the store-bought seasoning instead.

Ground Beef

Ground beef is the main protein in this casserole and helps to make it filling and satisfying. You can use any ground beef you like; just make sure it’s fully cooked before adding it to the casserole.

Heavy Cream

Heavy cream is used in this keto taco casserole recipe to add richness and creaminess. It helps balance the spices and gives the casserole a velvety texture.

While you can use regular milk as a substitute for heavy cream in this recipe, note that milk has a lower fat content than heavy cream, and this would leave the casserole less rich and creamy. Also, if you use milk as a substitute, you will need to adjust the amount you use. Start with less milk than the heavy cream required, and add more as necessary to achieve the desired consistency.

It’s also worth noting that regular milk has a higher carb content than heavy cream, so it may not be suitable for the keto diet, although it may be okay for a low-carb diet. If you are on keto and don’t want to use heavy cream, consider omitting it altogether and using additional eggs instead. Other possibilities include unsweetened coconut milk, almond milk, or cashew milk. These alternatives will give the casserole a different flavor and texture, but if you want to make this recipe, those should still work.

Shredded Cheddar Cheese

Cheddar cheese is the most commonly used type of cheese for taco casseroles. Cheddar has a creamy, tangy flavor that pairs well with the spicy flavors of taco seasoning and ground beef. It also melts well and helps to hold the casserole together.

That said, you can use any shredded cheese you prefer in your taco casserole. Some other options to consider include Monterey Jack, Colby Jack, pepper Jack, or a blend of different types of cheese. Feel free to experiment and find the cheese that you like the best.

If you’re looking for a dairy-free or vegan option, there are many plant-based cheeses on the market. Some possibilities include shredded vegan cheddar, mozzarella, or pepper Jack. You can find these cheeses at many health food stores or online.

When using shredded cheese in a taco casserole, it’s important to note that the texture and melting properties may vary depending on the cheese you choose. Some cheeses may melt more smoothly and evenly than others, so it’s a good idea to keep an eye on the casserole as it bakes and adjust the baking time as needed. 

Tip:  If you can, shred the cheese yourself, do so and opt for block cheese. Pre-shredded cheese often contain additives that may affect the melting properties.
