Ingredients
  

Zucchini & Prep
  • 2 large zucchini or 3 medium, halved lengthwise
  • Salt and black pepper
  • Olive oil for drizzling
  • 1 cup marinara or pizza sauce
Aromatics & Vegetables
  • 2 cloves garlic minced
  • 1/2 cup chopped onion
  • 1/2 medium bell pepper diced
  • 8 oz mushrooms chopped (optional)
  • 1/2 cup chopped olives Kalamata or black
  • 1/2 –1 cup chopped tomatoes fresh or canned
  • 1/4 cup fresh basil torn
Meat & Seasoning
  • 1/2 lb Italian sausage mild or hot
  • 1 tsp dried oregano
  • Pinch red pepper flakes optional
  • 1/2 tsp salt plus more to taste
Cheese
  • 1 cup shredded mozzarella
  • 1/2 cup grated Parmesan

Method
 

Prep the zucchini
  1. Heat oven to 375°F, or 400°F if you plan to pre-bake the shells.
  2. Cut each zucchini in half lengthwise.
  3. Scoop the center and seeds, leaving a 1/4-inch rim all around so the shells stay firm.
  4. Sprinkle a little salt and pepper inside the hollowed halves and let them sit a few minutes to release moisture.
  5. Pat dry with a paper towel.
  6. If using 400°F, pre-bake the empty zucchini shells for 15 minutes to tighten the texture.
Cook the aromatics
  1. Warm 2 tablespoons olive oil in a skillet over medium heat.
  2. Add the chopped onion and cook until soft and translucent.
  3. Add garlic and cook 1–2 minutes until fragrant, not browned.
Brown the sausage
  1. Add the sausage to the pan, breaking it up with a spoon.
  2. Cook until no pink remains and the edges caramelize.
  3. If the pan is very greasy, drain off a little fat.
Build the filling
  1. Add bell pepper, mushrooms (if using), oregano, and red pepper flakes. Cook until the vegetables soften and most liquid evaporates.
  2. Remove pan from heat.
  3. Stir in tomatoes, olives, basil, 1/2 cup Parmesan, and 1 cup mozzarella.
  4. Taste and adjust salt and pepper.
Assemble
  1. Spread a thin layer of marinara inside each zucchini shell.
  2. Spoon the filling into the boats and gently press it down to pack it in.
  3. Drizzle with a little olive oil and sprinkle extra Parmesan on top.
Bake
  1. If baking at 375°F: Bake filled boats about 30 minutes.
  2. If baking at 400°F: After the 15-minute pre-bake, fill the shells and bake another 10–15 minutes.
  3. Doneness cue: cheese is melted and golden in spots, and a fork slides into the zucchini with light resistance.
Finish and serve
  1. Let rest 5 minutes so juices settle.
  2. Top with fresh basil.
  3. Serve with extra marinara for dipping.

Notes

  • For firmer zucchini shells, always pre-salt or pre-bake. It keeps the boats from getting watery.
  • Fresh basil and tomatoes should be added just before baking for the brightest flavor.
  • Leftovers reheat best in the oven or air fryer so the top stays crisp.
  • This filling works great inside bell peppers or even spread on crusty bread as a toasted “boat.”
  • If you want a lighter version, use chicken or turkey sausage and go a little lighter on the cheese.
