Ingredients for Making Keto Mexican Casserole
- Olive Oil - Any keto-friendly oil works here. I used regular olive oil, not extra-virgin.
- Onion - Either white or yellow onion is excellent here.
- Jalapeno - Seeding the jalapeno and removing the white parts inside keep the heat to a minimum. If you would like a spicy dish, you can always skip this step. If you are especially heat-sensitive, poblano pepper is a milder option.
- Ground Beef - Whatever percentage of fat ground beef you have on hand works - you can always drain it after browning if it is too greasy. Ground turkey may be used in place of ground beef.
- Cream Cheese - Make sure that you use full fat cream cheese to keep this taco casserole keto.
- Taco Seasoning - I like to make my own; if you purchase taco seasoning, make sure you read the label to ensure that it is keto-friendly.
- Canned Diced Tomatoes - I like to buy the kind with peppers in them for extra flavor.
- Sour Cream - Use full-fat sour cream.
- Cheese - I used cheddar to keep this keto taco bake kid-friendly; pepper jack would be great here too.
Tips & Tricks
- If the meat you are cooking is high in fat, you can drain it after browning. This is entirely a matter of personal preference, but draining excess fat can help the texture of this Mexican low carb casserole.
- Have fun with the toppings for this! Shredded lettuce, diced tomatoes, avocado, sour cream, black olives, hot sauce, and fresh-squeezed lime juice are all great additions.
Serving Suggestions
Either Cabbage Rice or Cilantro Lime Cauliflower Rice are great sides for this recipe. A simple green salad is also a fabulous option.
Craving a shell? Serve this low carb taco pie in cheese taco shells, or use my almond flour tortillas. Keto tortilla chips are also a great option if you want to add a little gluten-free crunch.
Frequently Asked Questions
Yes - as long as you use full-fat sour cream, it is keto-friendly. Low-fat and non-fat should not be used on keto because they are higher in carbs.
You can. I recommend cooking the vegetables and browning the beef first.
Then, add the remaining ingredients other than the cheese and cook on low for 3 hours. Stir and add the cheese.
Cook for an additional hour.
No, because sour cream and cheese are not paleo. Make this paleo by using ½ cup of salsa and 1 beaten egg in place of the sour cream.
Omit the cheese and top with black olives after cooking
It can be, but don't always assume that it is! Many commercially available taco seasonings have added sugars in them that make them unsuitable for for a keto diet.
Make sure you read the label if you are buying taco seasoning!
I use homemade taco seasoning to make this taco meat with cream cheese, making it perfect for a keto diet.
