How to Make Keto Taco Casserole
Step 1: Prepare the Keto Corn Tortillas
If you’re feeling adventurous and want to make your own keto corn tortillas, go ahead and start there. They are the perfect low-carb substitute for regular tortillas and add an authentic taco texture. Otherwise, store-bought keto-friendly tortillas work just as well and save time.
Step 2: Sauté the Beef and Vegetables
Heat a large skillet over medium heat with about 2 teaspoons of olive oil to prevent sticking and add richness. Cook the ground beef along with diced onion and green pepper until the beef is nicely browned and the vegetables soften to release their sweet aromas. Using beef with at least 10-15% fat content keeps everything juicy and keto-friendly.
Step 3: Add the Taco Seasoning and Green Chiles
Sprinkle your homemade or store-bought taco seasoning over the cooked beef mixture and stir to coat evenly. Add the green chiles and continue cooking just a few minutes so all those brilliant flavors can meld together beautifully.
Step 4: Layer the Casserole
Grease your casserole dish lightly. Lay down a layer of keto tortillas—whole or cut into strips, whichever way you prefer. Spoon half of your seasoned beef mixture over that layer, then cover generously with shredded cheese. Repeat with another tortilla layer, the remaining beef, and top with more cheese.
Step 5: Add Cream and Bake
Pour the full-fat cooking cream slowly over the casserole to soak each cheesy layer, keeping this dish perfectly moist and luscious. Sprinkle chopped green onions on top to add a fresh, colorful touch. Bake the casserole covered with foil at 375°F (190°C) for 20 minutes, then remove the foil and bake for an additional 10 minutes to let the cheese bubble and turn golden.
How to Serve Keto Taco Casserole

Garnishes
Fresh garnishes elevate this casserole beautifully. Add dollops of sour cream or guacamole, sprinkle chopped cilantro, or slice up some jalapeños if you like heat. Each topping complements the savory layers, adding freshness, creaminess, or zing.
Side Dishes
Keep your sides light and complementary. A crisp green salad with avocado, a bowl of steamed broccoli, or even some roasted cauliflower rice keeps the meal low-carb and balances the richness of the casserole wonderfully.
Creative Ways to Present
For easy entertaining, consider serving the Keto Taco Casserole family-style, letting everyone scoop their portions with extra toppings on the side. Alternatively, portion it into individual ramekins before baking for charming personal servings that make your dinner feel extra special.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover Keto Taco Casserole in an airtight container in the refrigerator for up to 3 days. This dish tastes just as good reheated, and the flavors only deepen overnight.
Freezing
You can freeze the casserole before baking for a convenient future meal. Wrap it tightly with plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge before baking as directed.
Reheating
To reheat, cover the casserole with foil and warm in a 350°F oven for about 20 minutes or until heated through. Removing the foil in the last few minutes helps refresh that gorgeous golden cheese crust.
FAQs
Can I use ground turkey instead of beef?
Yes! Ground turkey works well, though you might want to add a bit of olive oil while cooking to keep the fat content keto-friendly and maintain moisture.
Are store-bought tortillas okay for this recipe?
Absolutely. Just make sure to find low-carb keto-friendly tortillas, or you can easily make your own to keep carbs minimal.
Is it possible to make this casserole dairy-free?
Substituting cheese and cream with dairy-free alternatives like coconut cream and vegan cheese can work, but the texture and richness may differ slightly.
How spicy is this casserole?
The heat level can be customized by adjusting the chili powder, red pepper flakes, or amount of green chiles you add. Feel free to dial it up or down based on your preference.
Can I add other vegetables?
Definitely! Zucchini, mushrooms, or even chopped spinach can blend nicely into the beef mixture to bump up nutrition and add variety.
