Nutritional Benefits of Key Ingredients
Grass-Fed Ground Beef: A Nutrient Powerhouse
Using good-quality grass-fed ground beef in this recipe not only enhances the flavor but also boosts the nutritional value. Grass-fed beef is rich in iron, which supports energy levels and oxygen transport in your body. It’s also packed with protein to help keep you full and maintain muscle mass on a keto diet.
For a keto diet, it’s crucial to use ground beef with at least 10% fat to ensure you’re getting enough fat content to keep the dish satisfying and keto-friendly. Additionally, grass-fed beef contains healthy fats like omega-3 fatty acids and conjugated linoleic acid (CLA), which have anti-inflammatory properties.
Keto Corn Tortillas: A Low-Carb Twist on a Classic
This casserole uses my homemade keto corn tortillas as a base layer to mimic traditional taco shells or chips. These tortillas are made with almond flour and just a touch of corn flour for that authentic taste while staying low-carb. Each tortilla contains only 2.65 grams of net carbs!
If you don’t have time to make homemade tortillas, you can use pre-made options like Tia Lupita’s keto corn tortillas (available on Amazon). However, I highly recommend trying my homemade version—it’s fresher, tastier, and surprisingly easy to make. You can find the full recipe here: Keto Corn Tortillas Recipe.
Variations and Customizations
Protein Options
While this recipe uses ground beef as its base, you can easily swap it out for ground turkey or shredded chicken if you prefer leaner options. Each protein brings its own unique flavor profile to the dish.
Cheese Choices
Feel free to experiment with different cheeses like Colby Jack or Pepper Jack for added spice. A Mexican blend works beautifully too if you want more variety in flavor.
Spice Level
If you love heat, add red pepper flakes or hot sauce to your ground beef mixture while cooking. For milder flavors, stick with green chiles and adjust your taco seasoning accordingly.
Keto Taco Casserole Recipe
Ingredients
- 8-10 keto corn tortillas homemade or store-bought
- 1 lb ground beef at least 10% fat for a keto-friendly option
- 1/2 cup onion diced
- 1/2 cup green pepper diced
- 1 tablespoon olive oil
- Homemade taco seasoning: chili powder garlic powder, cumin, paprika, red pepper flakes or you can use store bough one
- 1/2 can green chiles about 2 oz
- 1 cup full fat cooking cream
- 2 cups cheese cheddar & Monterey Jack, shredded
- 1/2 cup chopped green onions for topping
Instructions
- If you are going to prepare keto tortillas for this recipe, begin with that, just go to the recipe link mentioned in the ingredients list highlighted in green. 👆
And Here is How We Make the Rest of the Keto Taco Casserole:
- Heat a large skillet over medium heat and add about 2 teaspoons of olive oil. This helps prevent the ground beef from sticking and ensures it cooks evenly.
- Add the ground beef, diced onion, and diced green pepper to the skillet. Cook until the beef is browned and the vegetables are softened. It’s best to use ground beef with at least 15% fat for a keto diet, as it provides the necessary fat content to keep the dish satisfying and keto-friendly.
- Once the beef is browned, add your taco seasoning and stir well to coat the beef evenly.
- Add the green chiles and stir to combine. Cook for a few more minutes until the flavors meld together.
- In a greased casserole dish, lay down a layer of keto corn tortillas from my recipe linked in the notes or store bought. You can cut them into strips or leave them whole, depending on your preference.
- Spread half of the seasoned ground beef mixture evenly over the tortillas. Sprinkle a generous layer of shredded cheese on top.
- Repeat the layers: tortillas, beef mixture, and cheese.
- Pour the cream over each layer of cheese to ensure that the layers are soaked with mosture and don't end up dry.
- Sprinkle chopped green onions for extra flavor and color.
- Bake the casserole in a preheated oven at 375°F (190°C) for 20 minutes covered with foil, then remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden brown.
