Zucchini Pizza Casserole Recipe

I grow zucchini by the bushel, so this pizza casserole is one of my dinnertime go-to's. My hungry husband and kids gobble it right up. —Lynn Bernstetter, White Bear Lake, Minnesota
TOTAL TIME: Prep: 20 min. Bake: 40 min. YIELD:8 servings


  • 4 cups shredded unpeeled zucchini
  • 1/2 teaspoon salt
  • 2 large eggs
  • 1/2 cup grated Parmesan cheese
  • 2 cups shredded part-skim mozzarella cheese, divided
  • 1 cup shredded cheddar cheese, divided
  • 1 pound ground beef
  • 1/2 cup chopped onion
  • 1 can (15 ounces) Italian tomato sauce
  • 1 medium green or sweet red pepper, chopped


  • 1. Preheat oven to 400°. Place zucchini in colander; sprinkle with salt. Let stand 10 minutes, then squeeze out moisture.
  • 2. Combine zucchini with eggs, Parmesan and half of mozzarella and cheddar cheeses. Press into a greased 13x9-in. or 3-qt. baking dish. Bake 20 minutes.
  • 3. Meanwhile, in a large saucepan, cook beef and onion over medium heat, crumbling beef, until meat is no longer pink; drain. Add tomato sauce; spoon over zucchini mixture. Sprinkle with remaining cheeses; add red pepper. Bake until heated through, about 20 minutes longer.
  • 4. Freeze option: Cool baked casserole; cover and freeze. To use, partially thaw in refrigerator overnight. Remove from refrigerator 30 minutes before baking. Preheat oven to 350°. Unwrap casserole; reheat on a lower oven rack until heated through and a thermometer inserted in center reads 165°. Yield: 8 servings.

Recipe Note

Test Kitchen Tips

  • Italian sausage or ground turkey sub well in this casserole.
  • Make it vegetarian by skipping the meat and increasing the veggies. Mushrooms or finely chopped cauliflower (or a combination of the two) taste great.
  • This packs up nicely for weekday lunches.

    "Tasty - made you forget you didn't have noodles or a pizza crust in there. Hubby liked it."

    "Very tasty!! To those who thought it was too soggy/goopy, squeeze the zucchini in your fist to remove the extra liquid. We loved this."

    "Excellent recipe. I wouldn't call it pizza per se, reminded me more of carb-less lasagna. I cut the amount of ground beef in half, doubled the onions and added about as much mushrooms. I used jarred Barilla traditional pasta sauce. Next time I'm thinking of using only half the cheese in the zucchini mix and replacing that amount with more zucchini, and double the salt. I'll also add garlic as many commenters have suggested. It holds up well as leftovers."

    "So delicious! I did use fresh grated Parmesan cheese and topped with fresh sliced mozzarella. Didn't add any shredded mozzarella to the zucchini mixture only used Cheddar and Parmesan and still came out great!"

    "Made it with Italian sausage instead of ground beef and added 2 tsp minced garlic. Yummy! Everyone loved it! I like the zucchini crust especially since it cuts down on carbs. Will definitely be making this again!"

    "Excellent! I liked it better fresh out of the oven so I will stick to a 1/2 recipe (8" square pyrex) to limit leftovers. Delicious!! (PS - I used ground chicken instead of beef to lower cholesterol - couldn't tell one bit of difference.)"

    "This was fantastic! We don't eat a lot of pizza because of the carbs, so this is an incredible substitute for pizza! We will definitely be making it again!"

    "Very tasty, versatile crust. Great way to use up the zucchini overload. Even those who don't care for zucchini will enjoy it. Have made it with a layer of ricotta, fresh tomatoes and basil instead of the the meat sauce for a vegetarian alternative."

    "I also added some extra Italian seasoning and garlic powder. My husband, who usually does not care for vegetables, went back for more!"

    "This is also good as a Mexican casserole. Switch your cheeses to Mexican mix cheeses and pepper jack. Same with sauce, try rotel or even an enchilada sauce with chunky salsa."
