Ingredients
For the Zucchini Boats
4 medium zucchini
1 tablespoon olive oil
½ teaspoon salt
¼ teaspoon black pepper
½ teaspoon Italian seasoning
½ teaspoon garlic powder
For the Filling
1 tablespoon olive oil
1 lb (450 g) lean ground beef
½ small onion, finely diced
2 cloves garlic, minced
½ red bell pepper, finely diced
½ yellow bell pepper, finely diced
¾ cup diced tomatoes, preferably cherry or grape tomatoes
1 tablespoon tomato paste
½ teaspoon smoked paprika
½ teaspoon Italian seasoning
½ teaspoon dried oregano
¼ teaspoon red pepper flakes, optional
½ teaspoon salt, or to taste
¼ teaspoon black pepper
2 tablespoons chopped fresh parsley or basil
For the Cheese Topping
1 cup shredded mozzarella cheese
½ cup shredded cheddar or Monterey Jack cheese
2 tablespoons grated Parmesan cheese
1 tablespoon chopped fresh parsley or basil
Instructions
1. Prepare the Zucchini
Preheat the oven to 400°F (200°C).
Wash and dry the zucchini.
Cut each zucchini lengthwise in half.
Using a spoon, gently scoop out the center flesh, leaving about ¼ inch (6 mm) around the edges so the zucchini keeps its shape.
Finely chop the scooped zucchini flesh and reserve it for the filling.
Place the zucchini halves cut-side up on a parchment-lined baking sheet.
Brush lightly with olive oil and season with salt, black pepper, garlic powder, and Italian seasoning.
2. Pre-Bake the Zucchini
Bake the empty zucchini boats for 8–10 minutes.
This gives the zucchini a head start and helps prevent the finished boats from becoming watery.
Remove from the oven and set aside.
3. Cook the Beef Filling
Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
Add the ground beef and cook for 5–7 minutes, breaking it apart with a spoon.
Cook until browned and no longer pink.
Drain excess grease if necessary.
Add the diced onion and bell peppers.
Cook for 3–4 minutes, until slightly softened.
Add the minced garlic and cook for another 30 seconds.
Stir in the chopped zucchini flesh.
Add tomato paste, smoked paprika, Italian seasoning, oregano, red pepper flakes, salt, and black pepper.
Cook for 2–3 minutes, stirring frequently.
Add the diced tomatoes and cook for another 2–3 minutes, allowing some of the moisture to evaporate.
Turn off the heat and stir in the fresh parsley or basil.
4. Fill the Zucchini
Spoon the beef mixture generously into each zucchini boat.
Do not pack the filling too tightly; lightly mounding it over the zucchini works best.
5. Add the Cheese
Sprinkle each boat evenly with:
Mozzarella
Cheddar or Monterey Jack
Parmesan
Add a little extra chopped parsley or basil on top if desired.
6. Bake
Return the zucchini boats to the oven and bake at 400°F (200°C) for 15–20 minutes, or until:
The zucchini is tender but not mushy.
The filling is hot.
The cheese is melted and bubbling.
The top is lightly golden.
For a more browned cheese topping, broil for 1–2 minutes at the end. Watch carefully so the cheese does not burn.
7. Rest and Serve
Allow the zucchini boats to rest for 5 minutes before serving.
Garnish with fresh parsley, basil, or a small sprinkle of Parmesan.

Helpful Tips
Choose medium-sized zucchini so the boats cook evenly.
Don’t scoop the zucchini too deeply; leaving some flesh prevents the boats from collapsing.
If your tomatoes are especially juicy, cook the filling a little longer to remove excess moisture.
Lean ground beef works particularly well because it keeps the filling flavorful without making the zucchini watery.
You can substitute ground turkey or ground chicken for the beef.
For extra spice, add jalapeño or more red pepper flakes.
For a Mediterranean twist, add chopped olives and crumbled feta instead of cheddar.
Storage & Reheating
Refrigerator: Store cooled zucchini boats in an airtight container for up to 3–4 days.
Reheating: Reheat in a 375°F (190°C) oven for about 10–15 minutes, or microwave individual portions for 1–2 minutes.
Freezing: Freezing is possible, but zucchini can become softer and release water after thawing. For best texture, enjoy them fresh or refrigerated.
