How to Make Keto Pizza Casserole

Getting this easy keto dinner on the table is a breeze. Let’s get cooking!

Step 1: Preheat and Brown

First, preheat your oven. Set it to 375°F (190°C). Grab a large skillet. Brown your ground beef over medium-high heat. If you are using onion and garlic, add them now. Cook for the last few minutes. Make sure they soften. Then, drain off any extra grease.

Step 2: Simmer the Sauce

Now, stir in your diced tomatoes. Add the sugar-free tomato sauce. Next, add Italian seasoning. Season with salt and pepper. Bring this mixture to a simmer. Cook for about 5 to 7 minutes. Let the flavors blend. The sauce should thicken a little.

Step 3: Add Cheese and Toppings

Stir in half the pepperoni slices. Add 1 cup of mozzarella cheese. Toss in the Parmesan cheese. If you are using them, add olives and mushrooms now. Mix it all gently. This is where the magic starts.

Step 4: Assemble the Casserole

Get a 9×13 inch baking dish ready. Pour your meaty mixture into it. Spread it out evenly. This forms the base of your yummy Keto Pizza Casserole. It looks so good already!

Step 5: Top and Bake

Top the mixture with the remaining mozzarella cheese. Sprinkle the rest of the pepperoni slices over the top. This creates a beautiful cheesy crust. Bake for 20 to 25 minutes. Watch for melted, bubbly cheese. The casserole should be heated all the way through. It smells amazing!

Step 6: Rest and Serve

Carefully remove the casserole from the oven. Let it stand for a few minutes. This resting step is important. It helps everything set. Then, serve your delicious Keto Pizza Casserole piping hot. Enjoy every low carb bite!
