Cuisine: American

Author: Kasey Schwartz

Servings: 8

Prep Time: 15 minutes

Cook Time: 25 minutes

Total Time: 40 minutes

Equipment

1 9×13 baking dish
1 large skillet

Ingredients

4 medium zucchini
½ teaspoon salt
1 pound ground beef
1 red bell pepper, seeds removed, chopped
½ cup chopped white onion
1 teaspoon minced garlic
2 cups marinara sauce
¼ cup chopped basil
2 teaspoons olive oil
½ cup grated parmesan cheese
½ cup shredded mozzarella cheese

Instructions

Preheat the oven to 400°F (200°C). Grease a 9×13 baking dish with cooking spray.
Slice the zucchinis in half lengthwise. Scoop out the seeds and some flesh to create long wells, and arrange the zucchini halves in the prepared pan.
Sprinkle the zucchini with the salt and set aside while you prepare the filling.
In a large skillet over medium-high heat, cook the ground beef until no longer pink, about 8 minutes, breaking it into small crumbles as it cooks. Drain excess fat.
Add the chopped red bell pepper, chopped onion, and minced garlic to the skillet. Cook for about 4 minutes, until the vegetables are softened.
Stir in the marinara sauce and chopped basil. Bring to a simmer and cook 2–3 minutes, stirring occasionally to combine flavors.
Pat the zucchini boats dry with a paper towel to remove excess moisture, then brush them lightly with the olive oil.
Spoon the beef and sauce mixture into each zucchini boat, filling them generously.
Bake for 15 minutes. Remove the pan, sprinkle the zucchini with parmesan and mozzarella cheese, then return to the oven and bake another 10 minutes, until the cheese is melted and beginning to brown.
Serve hot as a satisfying, complete meal.

Storage:

Variations

Use a meat-based pasta sauce to skip browning ground beef. Simply fill the zucchini with the meat sauce.
Substitute ground turkey, ground chicken, or Italian sausage for ground beef.
Swap zucchini for yellow summer squash for a slightly sweeter, milder flavor.
Make it vegetarian with plant-based meat crumbles or seasoned black beans instead of beef.

Tips + Tricks

For a faster option, use a store-bought meat sauce and skip cooking the ground beef separately.
Try different proteins like ground turkey, chicken, or Italian sausage to change the flavor profile.
Yellow summer squash is a tasty substitute for zucchini and works the same way in this recipe.
For a vegetarian version, use seasoned plant-based crumbles or black beans in the filling.
