Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 1 pound ground beef

• 1 small onion, diced

• 2 cloves garlic, minced

• 1 packet low-carb taco seasoning (or 2 tablespoons homemade taco seasoning)

• 1/3 cup water

• 4 ounces cream cheese, softened

• 1/2 cup sour cream

• 1 cup shredded cheddar cheese

• 1 cup shredded Monterey Jack cheese

• 1/2 teaspoon salt

• 1/4 teaspoon black pepper

Optional toppings:

• Diced tomatoes

• Sliced jalapeños

• Chopped cilantro

• Sliced avocado

• Shredded lettuce

Directions

1. I preheat the oven to 375°F (190°C) and lightly grease a baking dish.

2. In a large skillet over medium heat, I cook the ground beef and diced onion until the beef is browned and the onion is softened.

3. I add the minced garlic and cook for about 30 seconds.

4. I stir in the taco seasoning and water, letting it simmer for a few minutes until slightly thickened.

5. I reduce the heat and mix in the cream cheese until fully melted and combined.

6. I remove the skillet from heat and stir in the sour cream, salt, and black pepper.

7. I transfer the mixture to the prepared baking dish and spread it evenly.

8. I sprinkle the shredded cheddar and Monterey Jack cheese over the top.

9. I bake for 20–25 minutes, or until the cheese is melted and bubbly.

10. I let it rest for 5 minutes before adding optional toppings and serving.

Variations

I sometimes swap ground beef for ground turkey or chicken for a lighter option. When I want extra vegetables, I add chopped bell peppers or spinach to the beef mixture. For more heat, I stir in diced green chilies or a dash of hot sauce. I also enjoy layering sliced zucchini at the bottom of the dish for added texture.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I warm portions in the oven at 350°F (175°C) until heated through, or microwave in short intervals. I can freeze the casserole for up to 2 months, thawing overnight in the refrigerator before reheating.
