Why You’ll Love This Keto Beef Enchilada Casserole
I don’t know about you, but some days I feel like there just aren’t enough hours to get everything done. Between managing family life, work commitments, and trying to maintain a healthy lifestyle, cooking can sometimes feel like a chore. On those busy days, I want something that’s quick to prepare, nutritious, and delicious enough to satisfy everyone at the table. That’s why casseroles have always been a lifesaver for me.
This keto beef enchilada casserole is one recipe I keep returning to. It’s a perfect blend of comfort food and health-conscious cooking. You get the rich, familiar Mexican flavours you love, but without the extra carbs that traditional enchiladas bring. Instead of layering the casserole like most recipes, I wrap the seasoned beef in low-carb tortillas, just like real enchiladas. This keeps the dish authentic but keto-friendly.
If you’re anything like me, you want to avoid takeout or processed meals that can upset your gut and hormones. This casserole uses wholesome ingredients like lean ground beef, green chilies, and a homemade or store-bought keto enchilada sauce that keeps net carbs low. Plus, the cheesy, saucy finish makes it feel indulgent without the guilt.
Whether you’re cooking for the whole family or just yourself, this recipe is a crowd-pleaser. It’s easy to make in a baking dish, reheats well for leftovers, and can be customized with your favourite toppings like sour cream and green onions. I promise, once you try it, it’ll become one of your favourite recipes too.

Ingredients That Make This Keto Beef Enchilada Casserole a Winner
Let’s talk about some of the key ingredients and why they’re so great for this recipe and your health.
Ground Beef and Taco Seasoning
I always opt for grass fed hormone-free beef because it’s packed with protein. Protein is essential for keeping you full and supporting muscle health, especially when you’re following a low-carb diet.
The taco seasoning and chili powder bring in that classic Mexican flavour and a nice medium heat that wakes up your taste buds without being too spicy.
Taco seasoning is a blend of spices like cumin, paprika, garlic powder, and oregano. These spices not only add flavour but also have antioxidant properties that can support your immune system. Plus, the chili powder and cayenne pepper can help boost metabolism and reduce inflammation.

Low Carb Tortillas Instead of Corn or Flour
Traditional corn and flour tortillas are delicious but can add a lot of extra carbs to your meal. If you’re keeping an eye on your net carbs, low-carb tortillas are a game-changer. And guess what, I have a perfect recipe for you right here. They wrap the beef mixture perfectly, giving you that authentic enchilada experience without the carb overload.
These keto tortillas are usually made with ingredients like almond flour, coconut flour, or other low-carb alternatives. They’re widely available at the grocery store or can be made at home if you’re up for it. Using low-carb tortillas means you don’t have to sacrifice texture or taste.
Green Chilies and Red Enchilada Sauce
Green chilies add a mild smoky flavour and a bit of texture to the beef mixture. They’re also a good source of vitamins A and C, which support skin and immune health. The red enchilada sauce is the heart of the dish, made from tomato sauce, garlic powder, and spices like cayenne pepper and chili powder. It adds warmth and depth of flavour.
You can use a store-bought sauce for convenience, but making your own keto enchilada sauce is surprisingly easy and lets you control the ingredients. I like to use tomato paste, chicken broth, and spices thickened with a bit of xanthan gum to keep it low-carb.
Cheese and Sour Cream
Cheese is one of my favourite parts of this casserole. I use a Mexican blend cheese along with pepper jack for a little extra kick. Cheese adds creaminess and a satisfying melt that makes every bite comforting.
And ohhh, how I love sour cream, it’s my BFF. Sour cream is another great addition. It adds tanginess and richness while providing healthy fats that help keep you full longer. Plus, it’s a perfect topping alongside chopped green onions or avocado slices.

How to Make Keto Beef Enchilada Casserole
1. Preparing the Ground Beef Mixture
Start by heating a tablespoon of avocado oil or olive oil in a large skillet over medium-high heat. Avocado oil is great because it has a high smoke point and contains healthy fats. Once the oil is hot, add the ground beef and cook until browned, breaking it up as it cooks.
Next, stir in your taco seasoning, chili powder, garlic powder, and black pepper. These spices bring that great Mexican flavour we’re aiming for. Add diced green chilies and a cup of your enchilada sauce. Let the mixture simmer for a few minutes so the flavours meld together and the meat stays juicy.
2. Assembling the Casserole
Now for the fun part. Instead of layering like some casseroles, you’ll wrap the beef mixture in your low carb tortillas. This keeps the dish close to traditional keto beef enchiladas.
Place each wrapped enchilada seam-side down in a greased baking dish. I like to use a casserole dish that’s about 9×13 inches – it’s perfect for this recipe. Once all the enchiladas are in the dish, pour the remaining enchilada sauce over the top. Then sprinkle generously with your Mexican cheese blend and pepper jack cheese.
3. Baking and Serving
Cover the casserole dish with aluminum foil and bake at 180°C (350°F) for 20 minutes. After that, remove the foil and bake for another 10 minutes or until the cheese is bubbly and golden.
Once it’s out of the oven, let it rest for about 5 minutes. This helps everything set and makes it easier to serve. When you’re ready to eat, top with sour cream, chopped green onions, and any other optional toppings you like – avocado slices or fresh cilantro work beautifully.

Health Benefits of This Low-Carb Mexican Casserole
You might be wondering if a low-carb meal like this can really fill you up. I get it. But with good quality unprossessed protein, healthy fats from cheese and sour cream and filling keto tortillas you will definitely feel satisfied.
Protein helps keep hunger at bay and supports muscle repair. Healthy fats from cheese and sour cream provide lasting energy and help balance hormones. The spices like chili powder and cayenne pepper aren’t just for flavour – they can boost metabolism and reduce inflammation.
Using low carb tortillas instead of traditional corn or flour tortillas significantly cuts down on net carbs, making this dish suitable for those following a low-carb or keto diet.
If you want to add more fibre and volume, serve the casserole with cauliflower rice. It’s a great low-carb side that complements the Mexican flavours perfectly.
Tips for Success and Variations
Make your own keto enchilada sauce: It’s easy and means you avoid extra carbs and preservatives. Use tomato paste, chicken broth, garlic powder, chili powder, and a pinch of xanthan gum to thicken.
Swap ground beef for ground turkey or chicken breast: If you prefer a leaner protein, these options work well and keep the dish light.
Add black beans sparingly: While not strictly keto, a small amount of black beans can add fibre and texture if your carb count allows.
Store leftovers in an airtight container: This casserole keeps well in the fridge and tastes even better the next day.
