  • Pepperoni slices: These add that classic pizza taste. Feel free to swap them for turkey pepperoni or even diced ham if you prefer.
  • Shredded mozzarella cheese: The gooey, melty goodness that binds everything together. You can use a dairy-free alternative if you’re avoiding cheese.
  • Bell peppers: Diced bell peppers bring a pop of color and sweetness. Any color works, so choose your favorite or mix them up!
  • Onion: Diced onions add depth and flavor. Red or yellow onions are great choices, but you can skip them if you’re not a fan.

How to Make Keto Pizza Casserole—Weeknight Pizza, Keto Style

Step 1: Preheat the Oven

Preheating your oven is crucial for even cooking. Set it to 350°F (175°C) so that when you pop in your Keto Pizza Casserole, it bakes perfectly. A hot oven helps the cheese melt beautifully and gives that golden finish we all love.

Step 2: Brown the Ground Beef

In a skillet over medium heat, add your ground beef. Cook it until it’s browned and no longer pink. This step is essential for flavor. Once cooked, drain any excess fat to keep your casserole from becoming greasy. Nobody wants that!

Step 3: Sauté the Vegetables

Add the diced bell peppers and onions to the skillet. Sauté them until they’re softened, about 3-5 minutes. This step enhances their flavors, making your casserole even more delicious. Trust me, the aroma will have your family gathering in the kitchen!

Step 4: Combine Ingredients

Now, stir in the marinara sauce and Italian seasoning. Mix everything well, ensuring the meat and veggies are coated in that rich sauce. This combination is what gives your Keto Pizza Casserole its signature taste. Season with salt and pepper to your liking.

Step 5: Layer the Casserole

In a greased baking dish, start layering. First, add half of the meat mixture, then sprinkle half of the mozzarella cheese and half of the pepperoni. Repeat these layers. This method ensures every bite is packed with flavor and gooey cheese. Yum!

Step 6: Bake the Casserole

Place your layered casserole in the preheated oven. Bake for 20-25 minutes, or until the cheese is bubbly and golden. Keep an eye on it; you want that perfect melt without burning. Your kitchen will smell heavenly during this time!

Step 7: Cool and Serve

Once baked, let your casserole cool for a few minutes before serving. This step is important as it allows the layers to set, making it easier to cut and serve. Plus, it prevents anyone from burning their mouth on that delicious cheese!

Tips for Success

  • Use a non-stick spray or oil to grease your baking dish for easy cleanup.
  • Don’t rush the browning of the beef; it adds depth to the flavor.
  • Feel free to mix in your favorite low-carb veggies for added nutrition.
  • Let the casserole cool slightly before serving for better slicing.
  • Store leftovers in an airtight container for up to three days.

Equipment Needed

  • Skillet: A non-stick skillet works best, but any frying pan will do.
  • Baking dish: A 9×13 inch dish is ideal, but you can use any oven-safe dish.
  • Spatula: For mixing and layering ingredients.
  • Measuring cups: Helpful for portioning ingredients, though you can eyeball it!

Variations

  • Vegetarian Option: Swap the ground beef for a mix of mushrooms, zucchini, and spinach for a hearty veggie version.
  • Spicy Kick: Add sliced jalapeños or crushed red pepper flakes to the meat mixture for a spicy twist.
  • Cheese Lovers: Experiment with different cheeses like cheddar or provolone for a unique flavor profile.
  • Low-FODMAP: Use green onions instead of regular onions and skip the bell peppers for a low-FODMAP version.
  • Herb Infusion: Fresh basil or parsley can be added before serving for a burst of freshness.

Serving Suggestions

  • Pair your Keto Pizza Casserole with a fresh green salad for a refreshing contrast.
  • Serve with a side of garlic butter zucchini noodles for a low-carb twist.
  • A glass of sparkling water with lemon complements the flavors beautifully.
  • For presentation, sprinkle fresh basil on top before serving for a pop of color.
