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

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.

    "Loved this recipe. The only thing I did differently was I cooked the peppers with beef and onions. Tastes even better as leftovers the next day!"

    "This recipe is really really good. I've also used the zucchini, cheese, and egg mix as the base for Eggplant Parmesan instead of pasta. Everyone loves it."

Made it in ramekins...a good way to serve it too...spray the ramekins tho...sausage substitute work's as well...biggest deal is getting ALL the water out of the Zucchini ...."

    "I have made this many times now and every time it's still fantastic! Only changes I've made is that I use frozen chopped peppers and onions and cook them with the hamburger, I also use plain tomato sauce and just add italian seasoning and garlic."

    "This is excellent. I loved that it tastes like pizza and the zucchini was essentially hidden in the dish. I did make a few changes - ground turkey instead of ground beef and I ran out of mozzarella cheese so I ended up using cheddar to replace it. I would absolutely make this again, maybe adding a few pizza toppings to it as well."

    "This deserves all the fantastic reviews! If you are looking for recipes that will work well with a spiralizer, I used my thin-cut zucchini noodles instead of shredding them and it was great. I loved seeing my kids inhale all the zucchini!"

    "I made this casserole on 11/1/16 and it's delicious! I did use 3 small red peppers, ground turkey in place of the beef, 2 cups shredded Pizza cheese blend and 1 cup Pepper-Jack/Cheddar cheese blend since I had those prepared cheeses on hand. I'd also added 1 tsp. salt and 1/4 tsp. pepper to the ground turkey/chopped onion and I used a 15-oz. can pizza sauce. I used a 3-qt. casserole. delowenstein"
