Ingredients
Beef Mixture
- 1 pound ground beef
- 1 small onion, diced
- 1 cup bell peppers, diced
- 1 cup diced tomatoes (canned or fresh)
- 1 tablespoon taco seasoning
- Olive oil for cooking
- Salt and pepper to taste
Casserole Base and Toppings
- 1 head of cauliflower, cut into florets
- 1/2 cup sour cream
- 1 cup shredded cheddar cheese
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Sauté Vegetables: In a large skillet, heat some olive oil over medium heat. Add the diced onion and bell peppers and cook until they soften, about 4-5 minutes.
- Cook Ground Beef: Add the ground beef to the skillet with the sautéed vegetables. Brown the beef thoroughly, breaking it up as it cooks. Stir in the taco seasoning, diced tomatoes, salt, and pepper, then cook for an additional 5 minutes to develop flavors.
- Prepare Cauliflower: Steam or boil the cauliflower florets in water for 5-7 minutes until tender but not mushy. Drain well and place the cauliflower evenly in a greased 9×13-inch baking dish.
- Assemble Casserole: Spread the cooked beef mixture evenly over the cauliflower layer. Dollop and spread the sour cream evenly over the beef layer, then sprinkle the shredded cheddar cheese on top.
- Bake: Bake the assembled casserole in the preheated oven for 25-30 minutes, until the cheese is melted, bubbly, and beginning to brown slightly.
- Serve: Remove from the oven and let the casserole cool slightly before serving to allow it to set and enhance flavors.
Notes
- You can swap cheddar cheese with Monterey Jack or a Mexican cheese blend for variety.
- For extra spice, add chopped jalapeños to the sautéed vegetables or use a spicier taco seasoning.
- To keep it keto-friendly, be sure to use full-fat sour cream and cheese.
- Steaming the cauliflower is preferred to retain nutrients and avoid sogginess in the casserole.
- This dish can be prepared in advance and reheated; add extra cheese on top before reheating for a fresh melt.
