It’s monster zucchini season, that time of year when people who have gardens are likely to go out and discover a giant zucchini has suddenly sprung up overnight. I want to remind you of these favorite Meat, Tomato, and Mozzarella Stuffed Zucchini Cups that I’ve made so many times when I had giant zucchinis that I needed to use. Despite the rather messy plating job in these photos, I love everything about this way of making stuffed zucchini from giant zucchini slices.

Don’t you think hollowing out a zucchini cup and filling it with meat and cheese sounds like a delicious way to use late-summer zucchini? I’m definitely a fan of round 8-ball squash for Stuffed Zucchini, but those can be hard to find, and these zucchini cups give a similar result. And this recipe for stuffed zucchini doesn’t have any rice or other grains, so it’s perfect for low-carb eaters, FTW!

What ingredients do you need for this recipe?

  • large zucchini or yellow squash
  • olive oil
  • onion
  • green pepper
  • Minced Garlic (affiliate link)
  • ground beef
  • ground turkey, turkey Italian sausage, or pork Italian sausage
  • Rao’s Pasta Sauce (affiliate link), or any tomato-basil pasta sauce with low sugar
  • mozzarella or other mild white cheese

What are Zucchini Cups?

This recipe uses “zucchin cups” created from slices of overly-large zucchini that have the center hollowed out to make a cup! I think this is such a great idea when you don’t want to make zucchini bread and the zucchini you have on hand are too large for your usual favorite zucchini recipes.

How to make the stuffed zucchini cups:

(Scroll down for complete recipe with nutritional information.)

  1. Start by cooking onion, green pepper, and Minced Garlic (affiliate link) for a few minutes in a bit of olive oil.
  2. Then remove the veggies, add a bit more olive oil, and cook the meat until it’s browned. Stir the green pepper, onion, and garlic back into the meat once it’s done.
  3. Mix in about 2 cups of flavorful tomato sauce and let it simmer until all the liquid has cooked off. Rao’s Pasta Sauce (affiliate link) is the lowest-carb commercial sauce. Once the liquid has cooked off, turn off the heat.
  4. Cut a large zucchini into slices about 2 inches thick. Be careful to make flat sides when you cut. This zucchini was not quite three inches across at the widest part.
  5. I decided I didn’t have quite enough zucchini for the amount of sauce, so I also used a yellow squash that had gotten a bit too large. I used a melon baller to hollow out the squash, which worked perfectly. Be careful not to make the bottom too thin, or the liquid will run out!
  6. By now the meat has cooled slightly, so mix in about 1 1/2 cups of Mozzarella or other mild cheese. (Use low-fat or full-fat mozzarella, your choice.)
  7. I like the zucchini to still have a tiny bit of crispness, so I stuffed the zucchini raw. Pack it in, heaping it up a bit over the top. Bake zucchini like this for 20 minutes at 350F/175C.
  8. After the zucchini cups have baked for 20 minutes, use the remaining 1/2 cup of cheese to sprinkle over the top of each, and bake about 25 minutes more. (You’ll get some on the baking sheet, so be sure you’ve sprayed it with non-stick spray!) 
  9. Serve hot. This makes quite a bit but extras can be stored in the fridge and reheated during the week!

Meat, Tomato, and Mozzarella Stuffed Zucchini Cups

Meat, Tomato, and Mozzarella Stuffed Zucchini Cups

Yield 8 servings
Prep Time 15 minutes
Cook Time 50 minutes
Total Time 1 hour 5 minutes

This recipe uses giant zucchini slices hollowed out to make cups filled with a meat, tomato, and mozzarella mixture.


  • 2 large zucchini or yellow squash, about 12 inches long
  • 2 tsp. + 2 tsp. olive oil (or more, depending on your pan)
  • 1/2 cup finely chopped onion
  • 1 green pepper, finely chopped
  • 2 T finely minced fresh garlic
  • 1 lb. ground beef
  • 12 oz. ground turkey, turkey Italian sausage, or pork Italian sausage (see notes)
  • 1-2 tsp. Spike seasoning (optional but recommended)
  • 2 C flavorful tomato-basil pasta sauce (with low sugar)
  • 2 cups mozzarella or other mild white cheese (see notes)


  1. Preheat oven to 350F/175C.
  2. Chop onion and green pepper.
  3. Heat 2 tsp. olive oil in a non-stick pan, then saute onion and pepper for 3-4 minutes, until just starting to soften.
  4. Add minced garlic and saute about 1 minute more, being careful not to brown the garlic.
  5. Remove the onion, pepper, and garlic mixture to a bowl.
  6. Add 2 tsp. more olive oil to the pan.
  7. Crumble in the ground beef and ground turkey (or ground sausage), season with Spike Seasoning (affiliate link) and cook over medium heat until the meat is well browned.
  8. Tilt pan to see if there is any extra fat, and remove with a spoon if there desired, then stir cooked vegetables and garlic back into the meat.
  9. Add tomato sauce and simmer until the mixture has thickened and liquid has cooked off, about 10 minutes, then turn off heat.
  10. While meat cools, cut zucchini into 2 inch thick slices, discarding ends.
  11. Use a sharp spoon or melon baller to hollow out a cup in each zucchini slice, leaving just over 1/4 inch of zucchini flesh. Be careful not to get too close to the skin or the cups will leak liquid when they cook.
  12. Spray baking sheet with nonstick spray and stand up zucchini cups, open end up.
  13. Stir 1 1/2 cups grated cheese into the cooled meat mixture (it doesn’t need to be completely cool), then spoon the meat-cheese mixture into zucchini cups, pressing down with the spoon and mounding it up a little over the top of the zucchini.
  14. Bake zucchini cups for 20 minutes, then remove from oven and use remaining cheese to top each one with a generous pinch of cheese.
  15. Put back in oven and bake 10-15 minutes more, until zucchini is slightly soft when pierced with a fork and cheese is melted and lightly browned.
  16. Serve hot.


Use any combination of ground meat you’d like, but use low-fat ground meat for the South Beach Diet and full-fat for low-carb or Keto. I would use Rao's Pasta Sauce (affiliate link) for this recipe. I used a blend of six cheeses called Italian blend.

  1. The small zucchini work better as an appetizer. If the zucchini is too big, it takes too long to cook. The filling was delicious. I added mushrooms to it. But the zucchini needs flavor. Maybe some kosher salt around the brim. 

    • I’m glad you like the filling. I like the idea of adding mushrooms. But I am confused by some parts of this comment. This isn’t an appetizer. And when I made it most of the zucchini was scraped out of the inside, so the outer edges were flavored by the sauce.

  2. Made this tonight and it was so yummy!! 

  3. Frankly I don't like mozzarella that much, but just can't wait to try this great recipe. Thanks 🙂

  4. Wow Kalyn! I just spotted your photo on Pinterest and had to jump right over for the recipe. This looks so delicious, and the zucchini ramekin is such a great idea!

    • Thanks Lisa! This is such an old recipe, but it's been pinned so many times I don't dare replace the messy photos! And these are really delicious; endless options for this idea.

  5. Bronwyn, so glad it was a hit!

  6. Thanks for this recipe, it was a hit! I have these enormous zucchini's straight from my garden that I had no idea what to do with 🙂 My husband and daughter had a thumb war over who got the biggest one (she won but he pulled rank!)

  7. Mary Ann you can certainly do that, but in the huge zucchini like I used the center of the zucchini has big seeds so I didn't want to use that part.

  8. Looks delicious. I'd shred the zucchini removed to make the cups and add that to the meat mixture. Will be making this recipe this week!

  9. Linnet, so glad you enjoyed it!

  10. I did a lot of research on how to use a giant zucchini (2 1/2 lbs) that a friend had given me. Of all the recipes and suggestions that came up, this looked the best, so I tried it tonight! It was a huge hit, even with my son who really doesn't like zucchini! I used sausage instead of the beef and turkey (and much less in proportion), added some mushrooms and a ripe tomato I had on hand,and also some cooked farro (any brown rice or grain would be nice). The farro gave the stuffing a nice texture. I also served it on a generous bed of homemade marinara sauce. It was EXCELLENT!! I left the zucchini walls a bit too thick, so it took longer to cook til soft – next time I'll scrape the walls to 1/4" per the recipe, and add the scrapings to the stuffing mixture. YUM!!! Thx so much!

  11. These are great, but they really need the full baking time to allow the zucchini to soften. I tried to rush it this last time and the zukes were just crisp tender (but still good!).

  12. Thank you for sharing this awesome recipe! My family and I loved it! I posted a feature about this recipe on my blog and put a link back to your blog! Thanks again!


  13. I went away and left hubby and son to take care of the garden, well to my surprise no one picked anything so I had one zucchini a little over a foot long and on the fat end was 5&1/2 inches around so stuffing it worked great.

  14. This looks fantastic! Nothing says summer like zucchini, tomatoes, and mozzarella. Thanks for the great idea for using – and enjoying – our huge zucchini harvest!

  15. I like this idea so much better than the zucchini boats where one uses a smaller, but whole zucchini, as the receptacle for the stuffing. These cups seem to provide a much more reasonably sized portion, Kalyn.


  16. Thanks Elizabeth! Such a fun way to use those big zucchinis.

  17. Love the presentation on these!!
