Ingredients

For the Zucchini Boats

• 4 medium zucchini
• 1 tablespoon olive oil
• 1 pound ground beef
• ½ small yellow onion, diced
• 3 garlic cloves, minced
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• ½ teaspoon kosher salt
• ¼ teaspoon black pepper
• 1½ cups marinara sauce
• 1 cup shredded mozzarella cheese
• ¼ cup grated Parmesan cheese
• 2 tablespoons chopped fresh parsley or basil

Ingredient Notes

Zucchini

Choose medium zucchini that are similar in size so they bake evenly. Very large zucchini can become watery and may have tougher seeds.

Ground Beef

Lean ground beef works well because it keeps the filling hearty without becoming greasy. You can use ground turkey or chicken if preferred.

Marinara Sauce

Use a flavorful marinara sauce since it seasons the entire filling. A thicker sauce works best and prevents the zucchini boats from becoming watery.

Cheese

Mozzarella gives the melty topping, while Parmesan adds salty flavor. You can also use provolone or an Italian cheese blend.

Herbs

Fresh parsley or basil brightens the finished dish and balances the rich beef filling.

How to Make Stuffed Zucchini Boats with Ground Beef

1. Prepare the Zucchini

Preheat the oven to 400°F.

Wash the zucchini and slice each one in half lengthwise.

Use a small spoon to scoop out the centers, leaving enough zucchini around the edges to hold the filling. Place the zucchini halves in a baking dish.

Brush lightly with olive oil and season with a pinch of salt and pepper.

2. Cook the Beef Filling

Heat a skillet over medium heat.

Add the ground beef and diced onion. Cook until the beef is browned and the onion softens, breaking the meat apart as it cooks.

Drain excess grease if needed.

Add the garlic, Italian seasoning, paprika, salt, and black pepper. Cook for another minute until fragrant.

3. Add the Marinara

Stir the marinara sauce into the cooked beef mixture.

Let it simmer for 3 to 5 minutes so the flavors come together and the filling thickens slightly.

4. Stuff the Zucchini

Spoon the beef mixture evenly into the hollowed zucchini halves.

Top each zucchini boat with mozzarella cheese and Parmesan.

Try to keep the filling slightly mounded but not overflowing too much.

5. Bake

Bake uncovered for 20 to 25 minutes, or until the zucchini is tender and the cheese is melted and lightly golden.

If you want a browner cheese topping, broil for 1 to 2 minutes at the end.

Garnish with fresh parsley or basil before serving.

Expert Tips

Don’t Scoop Too Deep

Leave enough zucchini flesh around the edges so the boats hold their shape after baking.

Use a Thick Sauce

Thin marinara can make the filling watery. A thicker sauce gives better texture.

Drain the Beef

If your beef releases a lot of grease, drain it before adding the sauce.

Don’t Overbake

Bake until the zucchini is tender but not mushy. It should still hold its shape.

Easy Variations

Italian Sausage Zucchini Boats

Replace half or all of the ground beef with Italian sausage for a bolder flavor.

Taco Zucchini Boats

Season the beef with taco seasoning, use salsa instead of marinara, and top with cheddar cheese.

Turkey Zucchini Boats

Use ground turkey for a lighter version while keeping the same method.

Extra Veggie Filling

Add mushrooms, bell peppers, spinach, or chopped zucchini centers to the beef mixture.

Storage

Store leftover zucchini boats in an airtight container in the refrigerator for up to 4 days.

Reheat in the oven at 350°F until warmed through, or microwave individual portions for a quicker option.

For meal prep, cook the beef filling ahead of time and store it separately. Stuff and bake the zucchini when ready to serve.

Freezing is not recommended because zucchini releases extra water after thawing.
