Ingredients for Stuffed Zucchini

Here are all the ingredients you need to make this keto Mexican zucchini boat recipe. Scroll to the recipe card at the bottom of the page to see the exact amounts for each ingredient.

  • Zucchini: You want them to be big enough to stuff, but not the extra-large overgrown zucchini you sometimes find at the end of the summer!
  • Ground beef: If you’d like, you can use lean, but I prefer regular ground beef. This will also work well with ground chicken, turkey, or pork.
  • Onion: Yellow or white both work. 
  • Green bell pepper: If you’re not a fan of the flavor of green bell pepper, you can swap in yellow, orange, or red.
  • Tomato sauce: Buy one that doesn’t have any added sugar if you are watching your carbs.
  • Taco seasoning: Homemade is great, but store-bought also works.
  • Cream cheese: Let this soften to room temperature.
  • Cheddar cheese: A Mexican blend, pepper jack, or Monterey jack works too.

How to Make Mexican Stuffed Zucchini Boats 

In addition to the ingredients listed above you will need a skillet, casserole dish, knife and cutting board. I’ve documented each step of the process so you can easily make this stuffed zucchini at home!

Prepare the Zucchini

Wash and dry the zucchini. Carefully slice the zucchini lengthwise and use a spoon or metal teaspoon to remove the center of the zucchini. Be sure to leave about 1/4 inch of the zucchini. You can use the portion of zucchini that you remove for stir fry, freeze for green smoothies or homemade vegetable broth.

Cook the Ground Beef

First, preheat the oven to 350 degrees F, as you will be baking the stuffed zucchini later. The next step is to brown the ground beef in a skillet set over medium heat, breaking up as you go. Drain off any grease.

Add Peppers and Onions

Next, add the onion and bell pepper and cook until they’re softened. This step should only take 3-4 minutes. If you prefer you can add some of the discarded zucchini you scooped out in step one that is an option.

Add the Seasoning

Add the tomato sauce, taco seasoning, and softened cream cheese to the skillet. Stir until the cream cheese has dissolved, then continue to cook over medium-low heat for 5-7 minutes, stirring occasionally, until the filling has thickened.

Add the Cheese

The finishing step is to add the cheese! Stir in 1/2 cup of the cheddar cheese. Stir the mixture well so the cheese is evenly distributed. This is a great time to do a little taste test and make sure the filling is to your liking. If you enjoy a spicy taco flavor you can add some hot sauce, or chopped jalapeños to the mix.

Stuff the Zucchini and Bake

Place the zucchini boats in a casserole dish and spoon the taco meat into them. Sprinkle the shredded cheese over the tops. Place the pan in the oven and bake at 350ºF for 25 to 30 minutes, or until the zucchini is tender and the cheese is bubbly.


Serve the stuffed zucchini as soon as they are done, piping hot from the oven! These Mexican zucchini boats are delicious served some simple sides to make a complete meal. Here are a few ideas:

Tips and Variations

Here are some simple tips to help you make sure your keto Mexican zucchini boats turn out perfect—and some ways to make the recipe your own!

  • If you want to get a head start on this recipe, you can make the filling a day or two in advance.
  • Don’t scoop out too much of the zucchini. Leave about a 1/4-inch shell to help the zucchini boats hold their shape.
  • Swap out the ground beef. Try using ground turkey or ground chicken instead.
  • Add some smoky heat. A roasted poblano pepper is a delicious swap for the green bell pepper!
  • Make them spicy. For some extra heat, add cayenne or your favorite hot sauce to the filling mixture, or stir in some diced jalapeños.
  • Don’t skimp on the toppings. Top with sour cream, guacamole, chopped tomatoes, or shredded lettuce for the full taco experience.

How to Store Zucchini Boats

Refrigerate keto Mexican zucchini boats in an airtight container (or wrap them in the pan) for up to 4 days. To reheat, place them in a 350ºF oven and bake for 10-15 minutes, until heated through. The microwave also works, but the zucchini boats will have a softer texture.

Can I Freeze This Recipe?

You can freeze these Mexican zucchini boats for up to 3 months. Thaw overnight in the refrigerator before reheating according to the instructions above.

Stuffed Zucchini FAQ

What can I do with the insides of the zucchini after scooping them out?

The insides of the zucchini can be saved and used in stir fries, soups, and more. They are a great way to sneak some extra veggies into your meals. You can also freeze them and add them to smoothies—they give smoothies a creamy texture without the added carbs or flavor of frozen bananas.

Why is my baked zucchini mushy?

If your zucchini is mushy, it may be overcooked. Try baking the zucchini boats for a shorter amount of time, until they are tender but not too soft. 

How do you hollow out zucchini?

To hollow out zucchini, cut it in half lengthwise, then use a metal spoon or teaspoon to scoop out the insides. Leave about 1/4-inch of flesh inside the zucchini so that it holds its shape during baking.
