Step-by-step instructions
How to make Low Carb Pizza Casserole (Easy, Cheesy & Family-Approved):
Prep the base:
- Preheat oven to 375°F (190°C).
- Rice the cauliflower or shred and squeeze zucchini to remove moisture. Cook briefly in a covered skillet with a splash of water until soft, then drain thoroughly.
Make the low-carb crust mixture:
- In a bowl, combine cooked riced cauliflower, eggs, Parmesan, almond flour, Italian seasoning, garlic powder, salt, and pepper. Mix until cohesive.
Form the base:
- Press the mixture into the bottom of a greased 9×13-inch baking dish to form an even layer.
Layer the casserole:
- Spread the sugar-free pizza sauce over the base.
- Sprinkle half the mozzarella and cheddar.
- Brown the ground beef with a pinch of salt and pepper, drain any excess fat, then layer evenly over the cheese.
- Add sliced pepperoni and optional vegetables.
- Top with remaining cheeses.
Bake:
- Bake uncovered for 20–25 minutes, until cheese is bubbly and edges are golden.
- Broil for 1–2 minutes if you want a browned top — watch closely.
Rest and serve:
- Let rest 5–10 minutes before slicing so layers set. Garnish with fresh basil if desired.

Tips for success
Tips for a perfect Low Carb Pizza Casserole (Easy, Cheesy & Family-Approved):
- Squeeze out moisture: Removing as much liquid as possible from cauliflower or zucchini prevents a soggy base.
- Pre-cook proteins: Browning ground beef or turkey first helps control moisture and intensifies flavor.
- Use room-temperature eggs: They bind the base better for an even crust.
- Avoid overloading vegetables: Too many watery veggies can make the casserole runny.
- Let it cool: Resting 5–10 minutes before serving makes slicing cleaner and portions neater.

- Streusel-style topping: For a savory low-carb streusel, mix 1/2 cup almond flour, 1/4 cup grated Parmesan, 2 tbsp melted butter, and a pinch of Italian seasoning; sprinkle over cheese before the last 10 minutes of baking for a crunchy finish.
