Ingredients
For the Casserole Base:
-
1.5 lbs (680g) ground beef (80/20 works well for flavor)
-
1 medium yellow onion, finely diced
-
1 medium bell pepper (any color), diced
-
3 cloves garlic, minced
-
1 (12 oz) bag riced cauliflower (or 1 small head, riced)
-
1 (10 oz) can Rotel diced tomatoes & green chilies, drained
-
2 tablespoons taco seasoning (sugar-free)
-
1 teaspoon ground cumin
-
1 teaspoon smoked paprika
-
Salt and black pepper to taste
-
2 tablespoons olive oil or avocado oil
For the Creamy Layer:
-
8 oz (225g) full-fat cream cheese, softened
-
½ cup sour cream
-
¼ cup heavy cream
For the Topping:
-
2 cups shredded Mexican blend cheese
-
½ cup shredded cheddar cheese
-
Optional toppings for serving: sliced jalapeños, fresh cilantro, diced avocado, sour cream, and sliced green onions
Instructions
Step 1: Prep and Preheat
Preheat your oven to 375°F (190°C). Lightly grease your 9×13 inch baking dish with oil or cooking spray.
Step 2: Cook the Vegetables and Beef
-
In a large skillet over medium-high heat, heat the olive oil. Add the diced onion and bell pepper. Sauté for 4-5 minutes until softened.
-
Add the minced garlic and cook for another minute until fragrant.
-
Add the ground beef to the skillet, breaking it apart with a spoon. Cook until no longer pink, about 6-8 minutes. Drain any excess fat if desired.
-
Stir in the riced cauliflower, drained Rotel tomatoes, taco seasoning, cumin, smoked paprika, salt, and pepper. Cook for another 5-7 minutes, stirring occasionally, until the cauliflower is tender and the flavors are well combined. Remove from heat.
Step 3: Prepare the Creamy Layer
In a medium bowl, combine the softened cream cheese, sour cream, and heavy cream. Mix with a hand mixer or whisk until smooth and creamy.
Step 4: Assemble the Casserole
-
Spread the beef and cauliflower mixture evenly in the prepared baking dish.
-
Dollop the creamy mixture over the top, then use a spatula to spread it into an even layer, covering the beef completely.
-
Sprinkle the shredded Mexican blend and cheddar cheeses evenly over the top.
Step 5: Bake
Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted, bubbly, and starting to turn golden brown.
Step 6: Rest and Serve
Remove the casserole from the oven and let it rest for 5-10 minutes. This allows the layers to set, making it easier to serve. Garnish with your choice of optional toppings, then slice into 6 portions and serve warm.
Recipe Notes
-
Make-Ahead: Assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. Bake as directed, adding 5-10 minutes to the cooking time if cold from the fridge.
-
Freezing: This casserole freezes well. Cool completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven.
-
Customization: Swap ground beef for ground turkey or chicken. Add a layer of sautéed mushrooms or zucchini for extra veggies. For a spicier kick, use hot taco seasoning or add a diced jalapeño to the beef mixture.
