For the Meat Sauce:
-
1 lb ground beef (or Italian sausage)
-
1/2 cup diced onion
-
2 garlic cloves, minced
-
1 cup low carb pizza sauce (no added sugar)
-
1/2 tsp dried oregano
-
1/2 tsp dried basil

1/4 tsp crushed red pepper flakes (optional)
Toppings:

1 ½ cups shredded mozzarella cheese
-
1/2 cup sliced pepperoni

1/4 cup sliced black olives

2 tbsp chopped fresh parsley or basil (for garnish)
Instructions
-
Preheat oven to 400°F (200°C). Lightly grease a 9×9” or similar casserole dish.
-
Prepare the cauliflower base: Steam or microwave cauliflower until fork-tender (6–8 minutes). Mash lightly, season with salt and pepper, and press into the bottom of the casserole dish.
-
Cook the meat: In a large skillet, sauté onions until soft. Add ground beef and cook until browned. Drain excess fat.
-
Season and sauce: Stir in garlic, pizza sauce, oregano, basil, and red pepper flakes. Simmer for 5 minutes.
-
Assemble the casserole: Spread meat sauce over the cauliflower base. Top with shredded mozzarella, then layer with pepperoni, olives, and bell peppers.
-
Bake: Bake uncovered for 20–25 minutes or until the cheese is melted and golden.
-
Garnish & serve: Let cool for 5 minutes, then top with chopped parsley or basil.
Notes
-
Swap cauliflower for zucchini or eggplant for variation.
-
For extra creaminess, spread a layer of ricotta or cream cheese before adding meat.

Great for meal prep — reheats well and freezes up to 3 months.
