Zucchini Pizza Casserole is a fun, family-friendly recipe that combines all the flavors of a classic pizza with a hearty, low-carb twist.

Layered with seasoned ground beef, marinara sauce, pepperoni, and melted mozzarella, this casserole is comforting, delicious, and easy to prepare.
This dish is perfect for weeknight dinners when you’re craving pizza but want something a bit healthier or gluten-free. It’s also a great way to sneak extra vegetables into a meal without sacrificing flavor.
