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 cup chopped onion
  • 1 can (15 ounces) Italian tomato sauce

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.

    "So versatile! I liked the posted review of the Mexican version as well. For that, I would switch the tomato sauce for enchilada sauce, or thick salsa drained slightly. Cheeses would be all cheddar or chedder/ & cheddar Jack for some spicy kick . Seasoning would be cumin or low sodium taco seasoning in both the meat mixture and in the enchilada sauce. Top with fresh minced cilantro or serve cilantro on the side

    Since zucchini is not at peak right now. So I MIGHT sub in " some" frozen & thawed cauliflower rice for "some" of the shredded zucchini.
    As written, this is a good recipe ...just BE VERY SURE TO squeeze the zucchini VERY well in several paper towels, after draining. Then add in garlic POWDER & some Italian seasoning to meat mixture & crust. I Also like to tightly roll up stacked leaves of fresh basil and cut into thin strips (chiffonade) Then top it on as a generous garnish . No wonder it is a contest winner ! Well Done !"

    "We love this "casserole"! We are on a low-carb diet, my husband and I, and have a craving for Italian food, especially pizza. This has solved our problem without busting the diet. After the first time I made it, I have changed it a bit, not in the recipe, but in the preparation. Since there are only 2 of us, I make the bottom "crust" in 2 8X8 inch pans, lined with parchment paper, partly up the side, and sprayed with cooking spray. I make half of the recipe in each, and cook it as directed. After cooling, I lift it out by the parchment, put both in a freezer container, and freeze until we are ready to use it. When we need a pizza, we take one "crust", thaw it in the 8X8 pan, and put the toppings on, cook it in the oven as the recipe calls for. It is almost as quick as a frozen pizza!"

    "I did as someone suggested, made half the recipe & put in 8x8 baking dish. I used Prego, and squeezed the zucchini with paper towels to remove more moisture. FABULOUS! Even my zucchini-hating hubby loves this! Will be making this again!!"

    "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."
