The smell of Italian sausage browning with garlic always pulls me right into the kitchen, and I love how it comes together in one dish with almost no cleanup.

Pepperoni slices add that classic pizza flavor, and a sprinkle of salt and black pepper rounds everything out. I love how simple the ingredient list isyou can grab it all in one quick trip and have dinner on the table in under an hour.

How It Comes Together

Fold in the cauliflower rice and half of the shredded mozzarella cheesethis creates a creamy, flavorful base.

Spread the mixture into your baking dish, then top with the remaining mozzarella cheese and pepperoni slices. Bake at 350°F for 25 to 30 minutes until the cheese is bubbly and golden around the edges. Let it cool for just a few minutes before slicing so the layers set up nicely.

Serving and Storage Tips

Serve this warm, straight from the oven, with a simple green salad on the side or steamed broccoli for extra veggies. Leftovers store beautifully in an airtight container in the refrigerator for up to three daysjust reheat in the oven or microwave until warmed through.

Pro Tip: If you’re reheating in the oven, cover with foil for the first few minutes so the cheese doesn’t dry out, then uncover to crisp it back up. It tastes just as good the next day, and the flavors meld together even more overnight.
