What Are Stuffed Zucchinis?

Baked stuffed zucchini is a healthy low-carb meal using low-carb vegetable zucchini shells as a taco shell.

They are also known as zucchini boats or zucchini tacos.

In a stuffed zucchini recipe, the zucchinis are cut lengthwise, cored, and filled with cooked meat like ground sausage, ground beef, ground turkey, or vegetarian filling.

The filled zucchini are then baked in the oven.

Are Stuffed Zucchinis Keto?

Not all stuffed zucchini recipes are keto-friendly because some use bread crumbs on top of the zucchinis.

But this ground beef stuffed zucchini recipe is keto-friendly, 100% made with low-carb ingredients.

How To Make Stuffed Zucchini

It is super easy to make stuffed zucchinis at home.


For the taco stuffed zucchini, you need:

  • Zucchinis – read below to learn how to pick them.
  • Ground beef or ground Italian sausage, it’s up to you. Both options make tasty keto stuffed zucchini boats.
  • Homemade taco seasoning – or a combination of cumin, paprika, chili, garlic powder, chili powder.
  • Olive oil
  • Yellow onion – red onion works as well. It’s slightly higher in carbs, so for a keto stuffed zucchini recipe, it’s better to use yellow or white onion.
  • Tomato paste
  • Beef broth
  • Sour cream or plain Greek yogurt to lighten the recipe and make healthy stuffed zucchini boats.
  • Grated cheddar or any hard grated cheese like grated mozzarella or grated Parmesan cheese.
  • Salt and pepper

Choose medium zucchinis

You must choose zucchinis that:

  • Fit your baking sheet – too long zucchinis won’t fit, and if you cut the zucchini ends, the filling drips out.
  • Are not too thick – choose medium zucchinis, about 8 inches long and 2 inches wide. Avoid large zucchini that take ages to bake and stay crunchy.

Prepare the zucchinis

Zucchinis are made at 95% water, and you don’t want all the vegetable water to end up in your dish. So first, cut the zucchinis lengthwise, keep the skin on, and don’t cut the sides!

Use a teaspoon to carefully scoop out the flesh from each zucchini half, as seen in the picture below.

Watch out. If you go too deep, you can break the zucchini halves. Discard the flesh from the zucchinis or set it aside to use in a keto soup recipe later.

Then, lay each zucchini boat on a large baking dish – at least 9-inch x 13-inch to fit 4 medium zucchini or 8 zucchini halves.

How to make stuffed zucchini

Lightly oil the dish with olive oil and sprinkle salt all over the zucchinis. The salt will extract the water from the zucchinis. They are going to sweat!

Set aside the zucchinis for 20 minutes while preparing the filling.

Pat dry

After 10 minutes, use an absorbent kitchen paper towel to pat dry the zucchini.

Cooking The Meat

In a large frying pan, heat olive oil, and cook the onion until fragrant.

Then, add ground beef and, using a spoon, crumble the beef to create small pieces of meat that grill evenly on all sides.

Finally, add taco seasoning, beef broth, sour cream, and tomato paste, and keep cooking the beef for 5-6 minutes until cooked through and fragrant.

The mixture should be thick and not runny. If too runny, keep cooking until it forms a paste and the liquid evaporates.

Filling The Zucchini Shells

Now, spray a large 9×13-inch baking sheet with olive oil. Next, lay the zucchini shells next to each other onto the baking sheet.

It’s fine if they touch each other.

Fill the zucchini with the cooked ground beef and add the grated cheese on top of each keto-stuffed zucchini boat.

Bake the stuffed zucchini ground beef and cheese for 15-25 minutes or until the cheese is melted.

  • Preheat oven to 400°F (200°C). Spray olive oil all over a large baking dish that fits the length of the zucchinis. I used a 9×13-inch baking dish that fits 8 medium zucchinis halves.
  • Cut the zucchinis in halves lengthwise, don't peel, don't cut sides, or the filling runs out when baked later.
  • Use a teaspoon to carefully scoop out the flesh of the zucchinis. Don't go too deep, or you can break the zucchini halves. Scroll up in this post to watch the step-by-step pictures.
  • Place each zucchini half next to each other on the baking dish. Sprinkle 1 teaspoon of salt all over the zucchini halves and set aside 20 minutes while cooking the meat. This step makes the zucchini 'sweat' out their water and avoids a watery dish.
  • In a large skillet, heat olive oil under medium/high heat. Add onion and cook for 2-3 minutes until fragrant.
  • Stir in ground beef and stir with a wooden spoon to crumble the meat into tiny pieces and cook on all sides.
  • Stir in the beef broth, spices, sour cream, and tomato paste, and keep cooking the meat for 5-8 minutes or until the meat is cooked through, and it forms a thick meat sauce, not runny. Stop the heat, keep the meat in the skillet.
  • Now, use an absorbent paper towel to pat dry the zucchini halves and remove all the water they released.
  • Use a spoon to fill each zucchini half – you should fit about 1/3 cup of ground meat per zucchini half.
  • Top up each zucchini half with grated cheese.
  • Place the baking dish in the center rack of the oven and bake for at least 15 minutes or until the cheese is melted and grilled.
  • Serve hot with toppings of your choice like diced avocado, fresh cilantro, sour cream, or yogurt, chopped yellow bell pepper, or chopped tomatoes.


  • Store in the fridge in an airtight container for up to 3 days or freeze for up to 3 months. Thaw in the fridge. Rewarm in a skillet, oven, or microwave until piping hot.

    2 Thoughts On Keto Stuffed Zucchini with Ground Beef
  1. 4 stars
    The link to your Taco Seasoning leads to carrot taco shells (title) but will not open.
    I made zucchini boats years ago, although I wasn’t following the Keto Diet at the time. I have been trying to find new inspiration for my favorite vegetable, the zucchini. This recipe inspired me. Thank you.
    I am just sad that I couldn’t read your taco seasoning recipe.
