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. So today I want to remind you about 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 big slice of zucchini to make a cup and then 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 stuffed 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 are Zucchini Cups?

This recipe uses “zucchini 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.

Are these stuffed zucchini cups low in carbs?

These tasty stuffed zucchini pieces use ground beef, sausage, onion, green pepper, Mozzarella cheese, and low-carb Rao’s Pasta Sauce (affiliate link) for a stuffed zucchini recipe with only about 7.5 net carbs per serving.

How to make Stuffed Zucchini Cups:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

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

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.

Ingredients

• 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)

Instructions

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.

Notes

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.
