What Is a Low Carb Pizza Casserole?

A Low Carb Pizza Casserole is a crustless version of pizza made with layers of seasoned ground meat, sugar-free tomato sauce, melted cheese, and your favorite toppings.
It tastes like a cross between lasagna and deep-dish pizza — but without the carbs.

This dish is perfect for keto, low-carb, gluten-free, or diabetic-friendly diets.

Ingredients You’ll Need

For the Base Layer

• 1 lb ground beef or Italian sausage
• ½ tsp salt
• ¼ tsp black pepper
• 1 tsp garlic powder
• 1 tsp Italian seasoning

For the Sauce

• 1 cup sugar-free marinara sauce (Rao’s or homemade keto marinara)

For the Toppings

• 1 cup shredded mozzarella cheese
• ½ cup shredded cheddar or provolone
• ½ cup sliced pepperoni
• ¼ cup black olives (optional)
• ¼ cup chopped bell peppers or mushrooms

💡 Pro Tip: Swap beef for ground turkey or chicken if you prefer lighter protein.

Step-by-Step Instructions

1 – Cook the Meat

In a large skillet, cook ground beef (or sausage) over medium heat until browned. Drain excess fat and season with salt, pepper, garlic powder, and Italian seasoning.

2 – Add the Sauce

Pour in sugar-free marinara sauce, stir well, and simmer for 5 minutes to thicken slightly.

3 – Assemble the Casserole

Spread the meat mixture into a greased 9×9 baking dish.
Top with mozzarella, cheddar, and your favorite pizza toppings.

4 – Bake

Bake at 375°F (190°C) for 15–20 minutes, or until cheese is melted and bubbly.

5 – Serve

Let cool for 5 minutes before slicing. Serve with a side salad or roasted veggies for a full meal.

How Many Carbs Are in Pizza Casserole?

This Low Carb Pizza Casserole contains approximately 4–6 net carbs per serving, depending on the brand of marinara sauce and toppings used.

To keep it extra low-carb:
✅ Choose sugar-free marinara sauce.
✅ Skip onions or sweet peppers if counting carbs strictly.
✅ Stick with meats, olives, and cheese as main toppings.

What Are Common Keto Pizza Mistakes?

Even seasoned keto cooks can make a few slip-ups. Avoid these common keto pizza pitfalls:

1️⃣ Using sugary sauces — check labels for hidden sugars.
2️⃣ Overloading on toppings — balance fat and protein for macros.
3️⃣ Using low-fat cheese — full-fat melts better and keeps you fuller.
4️⃣ Skipping seasoning — low-carb dishes need big flavor!
5️⃣ Not letting it cool — the casserole sets better after a few minutes.

💡 Bonus Tip: Bake uncovered so your cheese gets bubbly and browned on top.

What Are Low-Carb Pizza Alternatives?

If you love pizza but want variety, try these:

• Cauliflower crust pizza – made with riced cauliflower and cheese.
• Zucchini pizza boats – hollowed zucchinis filled with sauce and cheese.
• Portobello mushroom pizzas – use large caps as crusts.
• Meat crust pizza – use seasoned beef or chicken as the “crust.”
• Eggplant rounds – grilled slices topped with sauce and mozzarella.

Why Is Caulipower Pizza So High in Carbs?

Although marketed as a healthier pizza, Caulipower and similar brands use rice flour, cornstarch, and tapioca starch in their crusts — all of which increase carb counts.
Homemade versions (like this casserole) skip those ingredients, relying on cheese, eggs, and veggies for binding.

💡 Always read nutrition labels — not all “cauliflower crusts” are truly low-carb.

Storage & Meal Prep Tips

• Refrigerate: Store leftovers in airtight container for up to 4 days.
• Freeze: Cool completely, slice into portions, and freeze up to 2 months.
• Reheat: Microwave or bake at 350°F for 10 minutes until hot.

This casserole reheats beautifully — perfect for meal prep or weekday lunches.
