Zucchini Pizza Casserole

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.
  • Makes
    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


  • Preheat oven to 400°. Place zucchini in colander; sprinkle with salt. Let stand 10 minutes, then squeeze out moisture.
  • 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.
  • 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 green pepper. Bake until heated through, about 20 minutes longer.
  • 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°.

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.

      Great recipe. I used pizza sauce (Prego) as recommended by other reviewers. I also added 1/2 teaspoon pepper, 1/2 teaspoon salt, 1 teaspoon pizza seasoning, 1/2 teaspoon basil, 1/2 teaspoon Italian seasoning, 1 teaspoon frozen pizza seasoning, and 1/2 t. garlic powder. Everyone loved it - including the 2 and 8 year old grandchildren.

      It is like a pizza without a bread crust. Good recipe for a gluten free diet. Very tasty.

      My family loved this but I did make changes. I used bulk Italian sausage instead of ground beef and pizza sauce instead of tomato sauce. I don't think it would have tasted like pizza otherwise. The crust had to be baked longer than recommended and the zucchini needed more time in the colander to draw out the moisture. Knowing this now and making those changes I will be making it again.

      Great recipe and really easy to make hotdish. (Can't believe anyone from Minnesota would call it a casserole)

      I made this with the veggies from my garden. It was so tasty that I will definitely make it again. I found that it did not feed eight, unless you have several sides or a giant salad. The reason I like casseroles so much is so I don't have to make sides ;-). I feel to have it as a stand alone meal, that the more appropriate servings listed would be 5 or 6. Next time I make it (which i will for sure), I will double the recipe if I intend to feed more than 4. Loved it!

      Love Love Love the zucchini crust. I've made the recipe several times, similar to as written, I substituted pizza sauce. Also, I take the grated zucchini and place on a clean dishtowel and wring out the moisture, no salt no colander. This last time, I made it like a real pizza. DELICIOUS
