Equipment (7)

Large rimmed baking sheet, about 18×13 inches (46×33 cm)
Parchment paper
12-inch (30 cm) heavy skillet
Spoon or melon baller for scooping
Clean kitchen towel or paper towels
Pastry brush
Instant-read thermometer

Steps

Before you start

Choose straight, medium zucchini about 7–8 inches (18–20 cm) long and 8 oz (225 g) each. Very large ones are watery and seedy.
Heat the oven to 425°F (220°C) with a rack in the center before you start cutting.
Remove the sausage casings if you're using links. Bulk sausage can go straight into the pan.
The shells are baked once empty and again once filled, so read the steps through to plan your timing.

1
Heat oven, prep panOven 425°F / 220°C
- Position a rack in the center of the oven and heat it to 425°F (220°C).
- Line a large rimmed baking sheet with parchment paper.

Ready when: Oven reaches 425°F (220°C)
2
Halve and scoop zucchini
- Cut each zucchini in half lengthwise.
- Use a spoon to scoop out the seedy center, leaving a wall about ¼ inch (6 mm) thick on the sides and bottom.
- Chop the scooped flesh into ¼-inch (6 mm) pieces, place it on a clean towel, and squeeze firmly to remove as much liquid as you can.
- You should have about 1½ cups of chopped flesh.
+ Show details− Hide details
Ready when: Shells hold their shape with walls about ¼ inch thick and no holes
Tip: Scoop gently. If you pierce the bottom, the filling will leak and the boat will turn soggy.
3
Pre-bake the shellsOven 425°F / 220°C
- Arrange the 8 shells cut side up on the lined baking sheet.
- Brush the insides and edges with the olive oil and sprinkle evenly with the salt.
- Bake for 12 minutes at 425°F (220°C), until the edges are just starting to soften and the cut surface looks slightly dry.
- Leave the oven on.

Ready when: Edges are slightly softened and a knife meets a little resistance in the thickest part
Tip: Pre-baking drives off water so the finished boats aren't soggy. Start the filling while they bake.
4
Brown the sausage
- Heat a 12-inch (30 cm) skillet over medium-high heat for 1 minute.
- Add the sausage and break it into ½-inch (1 cm) crumbles with a wooden spoon.
- Cook, stirring occasionally, for 6–8 minutes.
- Spoon off all but about 1 tablespoon of the rendered fat.
+ Show details− Hide details
Ready when: Sausage is browned in spots with no pink remaining and reads at least 160°F (71°C)
Tip: Don't crowd the pan. If the sausage steams instead of browning, cook it in two batches.
5
Cook the vegetables
- Reduce the heat to medium.
- Add the diced onion and the squeezed zucchini flesh to the sausage.
- Cook, stirring often, for 5–6 minutes.
- Stir in the garlic, oregano and red pepper flakes (if using) and cook for 30 seconds more, until fragrant.
+ Show details− Hide details
Ready when: Onion is soft and translucent and no liquid pools in the pan
Tip: Garlic burns quickly and turns bitter. Stir it constantly and move on as soon as it smells fragrant.
6
Mix the filling
- Remove the skillet from the heat.
- Stir in 1 cup (240 ml) of the marinara, ½ cup (30 g) of the panko and ¼ cup (20 g) of the Parmesan.
- Let the filling sit for 5 minutes so the panko absorbs the sauce and the mixture holds together.
+ Show details− Hide details
Ready when: Filling is thick and scoopable, not soupy
Tip: If the mixture looks wet, stir in another tablespoon of panko.
7
Fill and top the boats
- Mound the filling into the pre-baked shells, dividing it evenly (about ⅓ cup each) and pressing lightly.
- Spoon the remaining ½ cup (120 ml) marinara over the filling.
- Mix the remaining ½ cup (40 g) Parmesan with the remaining ¼ cup (15 g) panko and sprinkle it evenly over the tops.
+ Show details− Hide details
Ready when: Each boat has a generous mound with the topping covering the sauce
Tip: The filling should mound above the rim. It will settle as it bakes.
8
Bake until goldenOven 425°F / 220°C
- Bake on the center rack at 425°F (220°C) for 18–22 minutes.
- The boats are done when the topping is deeply golden, the sauce is bubbling at the edges and a paring knife slides easily into the zucchini wall.
- For extra browning, broil on high for 1–2 minutes, watching closely.
+ Show details− Hide details
Ready when: Golden topping, bubbling sauce, knife slides easily into the zucchini, and the filling reads 165°F (74°C)
Tip: Broilers go from golden to burnt in seconds, so don't walk away.
9
Rest and garnish
- Let the boats rest on the pan for 5 minutes so the filling sets and the zucchini cools enough to handle.
- Scatter with the basil and serve two boats per person.
+ Show details− Hide details
Ready when: Bubbling has stopped and the filling holds its shape when you lift a boat
Tip: Use a wide spatula, supporting each boat at both ends, to move it without splitting.

Tips

Squeeze the chopped zucchini flesh in a towel. Skipping this is the main cause of watery boats.
Choose similar-sized zucchini so all the shells cook at the same rate.
Taste the marinara before you use it. Jarred sauces vary a lot in salt, which affects the whole dish.
Serve with a green salad or crusty bread to soak up the sauce on the pan.

Make ahead

"Assemble the boats through step 7 up to 24 hours ahead. Cover the baking sheet tightly and refrigerate. Hold the Parmesan-panko topping back and sprinkle it on just before baking. Bake straight from the fridge, adding 5–8 minutes to the bake time, until the filling reaches 165°F (74°C)."

Storage & reheating

"Room temperature: up to 2 hours. Refrigerator: store cooled boats in an airtight container for up to 3 days. Freezer: freeze baked boats on a tray, then wrap individually for up to 2 months. Reheat refrigerated boats at 350°F (175°C) for 12–15 minutes, or frozen ones for 25–30 minutes, covered with foil for the first half, until hot throughout. A microwave works but softens the topping."

Substitutions

Italian sausage, mild or hot → ground turkey or chicken plus ½ tsp fennel seed and an extra ¼ tsp salt. Cook poultry until it reaches 165°F (74°C). It's leaner, so add 1 tbsp olive oil to the skillet.
panko breadcrumbs → plain dried breadcrumbs. Use ⅔ of the amount, as fine crumbs absorb more. The topping will be less crunchy.
Parmesan cheese → Pecorino Romano. Saltier and sharper, so you may want to skip the added kosher salt on the shells.
medium zucchini → yellow summer squash or small eggplant. Squash cooks the same. Eggplant needs 5–10 extra minutes in the pre-bake.
