Ingredients List

Gather these simple pantry staples for your low carb pizza casserole, and you’ll have pizza vibes in casserole form. I’ve included sensory notes and smart swaps to keep it flexible and flavorful—think melty cheese, zesty sauce, and crispy edges that scream “pizza” without the guilt.

• 1 lb lean ground beef: Go for 93% lean to slash fat by 20% while keeping it juicy and beefy.
• 8 oz pepperoni slices: High-quality, uncured pepperoni for that spicy, smoky punch—sub turkey pepperoni for a lighter twist.
• 8 oz cream cheese, softened: Creamy and rich, it binds everything like a keto dream; use full-fat Greek yogurt if dairy-free.
• 2 cups shredded mozzarella cheese: Freshly shredded melts silkier than pre-shredded—part-skim for fewer calories.
• 1 cup low-sugar pizza sauce: Brands like Rao’s keep sugars under 4g per cup; homemade with crushed tomatoes works too.
• 1 cup diced bell peppers: Red, green, or yellow for crunch and subtle sweetness—swap for zucchini if peppers aren’t your fave.
• 1/4 cup sliced black olives: Optional briny pop; omit for fewer calories or use green olives for variety.
• 1 tsp Italian seasoning: Oregano, basil, and thyme magic—double it for bolder flavor.
• 100g chopped mushrooms or spinach: Boosts veggies and umami; sauté mushrooms first or wilt spinach for texture.

You’ll need a 9×13-inch baking dish and a skillet. Serves 8 hungry pizza lovers.

Step-by-Step Instructions

Follow these foolproof steps for a bubbly, golden low carb pizza casserole every time. I’ve added pro tips to make it feel like I’m in your kitchen, personalizing for beginners or pros.

Step 1: Preheat and Prep the Dish

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with avocado oil spray. Pro tip: Line with parchment for effortless slicing—cuts cleanup by half!

Step 2: Brown the Beef

In a skillet over medium heat, brown 1 lb lean ground beef for 5-7 minutes, breaking it up with a wooden spoon. Drain excess fat using a paper towel-lined colander—removes up to 30% more grease for a lighter bite. Season lightly with salt.

Step 3: Mix the Creamy Base

Off heat, stir in 8 oz softened cream cheese and 1 cup low-sugar pizza sauce until smooth and velvety, about 2 minutes. Tip: Microwave cream cheese for 20 seconds if not fully soft—it blends like butter, preventing lumps.

Step 4: Layer in the Dish

Spread the beef mixture evenly into the prepared baking dish. Scatter 1 cup diced bell peppers, 100g chopped mushrooms or spinach, and 1/4 cup black olives on top. Sprinkle 1 tsp Italian seasoning for that authentic pizza aroma.

Step 5: Cheese and Pepperoni Heaven

Blanket with 2 cups shredded mozzarella, then artfully arrange 8 oz pepperoni slices. Personalize: Add jalapeños for heat or extra cheese for ultra-gooey pulls.

Step 6: Bake to Perfection

Bake uncovered for 20-25 minutes until edges bubble and cheese turns golden. For crispy pepperoni cups, broil on high for 1-2 minutes—watch closely to avoid burning!

Step 7: Rest and Serve

Let cool 5 minutes to set. Slice into squares—pro trick: Use a pizza cutter for clean edges mimicking real slices.
