Stuffed Zucchini Boats

Ingredients

• 3 mediumcourgettes, halved
• 1 tspsalt
• 1 tspblack pepper
• 680 gmild or spicy Italian sausage
• 1 mediumsweet onion, finely diced
• 3 medium clovesgarlic, minced
• 1 jar (680 g)prepared marinara sauce, divided
• 45 gtomato purée
• 1½ tspdried Italian seasoning, divided
• ½ tspcrushed red chilli flakes (optional)
• 160 gpart-skim or whole-milk ricotta
• 1 largeegg
• 3 tbsp (about 15 g)grated Parmesan, divided
• 2 cups (about 200 g)shredded mozzarella

Instructions

1. 1

   Preheat the oven

   Heat the oven to 200°C (400°F). Coat a grill pan or a 33 × 23 cm (13 × 9-inch) baking dish with cooking spray.

2. 2

   Prepare courgettes

   Use a teaspoon to scoop out the seeds and some of the flesh, leaving a border at least ⅓ inch (about 8 mm) thick. Set the halves side by side on the prepared pan and season to taste with salt and black pepper.

3. 3

   Cook sausage filling

   Cook the sausage and diced onion in a large frying pan over medium-high heat for 5–8 minutes, until no pink remains. Add a little olive oil only if needed; the sausage may provide enough fat. Stir in the garlic and cook for 1 minute more, then drain off any excess fat.

4. 4

   Simmer the sauce

   Add 2 cups of marinara sauce, the tomato purée, 1 teaspoon of Italian seasoning and the chilli flakes, if using, to the pan. Leave out the flakes if using spicy sausage or if you prefer less heat. Simmer for 2–3 minutes, just until the tomato purée has dissolved and the sauce is combined, then remove from the heat.

5. 5

   Mix the ricotta

   In a small bowl, stir together the ricotta, egg, 1 tablespoon of Parmesan and ½ teaspoon of dried Italian seasoning.

6. 6

   Fill the boats

   Divide half of the mozzarella among the courgette halves, sprinkling it into the bottom of each boat. Spoon the ricotta mixture evenly over the cheese.

7. 7

   Add sausage topping

   Spoon the sausage mixture over the ricotta. Scatter the reserved 1 cup of mozzarella and 2 tablespoons of grated Parmesan on top.

8. 8

   Bake until tender

   Transfer the dish to the oven and bake for 22–25 minutes. Check doneness with the tip of a knife; it should slide easily into the courgette.

9. 9

   Serve with sauce

   Serve straight away, with the remaining marinara sauce warmed and offered on the side if desired.

10. 10

    Make homemade sausage

    To make your own sausage, mix 680 g ground pork, turkey or chicken with 1½ teaspoons salt, 1 teaspoon dried Italian seasoning, 1 teaspoon fennel seed, 1 teaspoon granulated garlic or garlic powder, 1 teaspoon onion powder and ½–1 teaspoon crushed red pepper flakes, adjusting to taste or omitting them. In Step 3, brown this mixture with the diced onion and garlic, then continue with the recipe.

What are stuffed zucchini boats?

Stuffed zucchini boats are courgette halves hollowed out and filled before baking. This version has the familiar Italian-American combination of sausage, tomato sauce and cheese, finished in the oven until the courgette is tender.

The method makes a substantial main from a simple vegetable base: the sausage brings savoury depth, while ricotta tucked beneath the topping keeps each bite creamy.

Nutrition and macros by portion

The nutrition label shows one serving as written: 578 calories, 32g protein, 13g carbs, 35g fat.

The sausage and cheeses provide most of the protein and fat, while the marinara and courgettes contribute some of the carbohydrates. Balance the plate with a generous green salad or other non-starchy vegetables.

Choosing the courgettes

Size matters: medium courgettes are easier to fill and bake more evenly than very large ones. Scoop out the seeds and some flesh, but leave the stated border so each half can hold its filling.

Season the hollows before filling. The recipe gives salt and pepper to taste, so keep in mind that the sausage and cheeses may already be salty.

Building the sausage filling

Brown the sausage with the onion: cook until no pink remains, breaking up the meat as it cooks. Drain excess fat before adding the tomato ingredients so the filling is not unnecessarily greasy.

Tomato purée: a short simmer with the marinara helps it blend into the filling. The mixture should be combined and spoonable before it goes into the courgettes.

Layering for a creamy centre

Cheese base: put half the mozzarella into the courgette boats first, then spoon the ricotta mixture over it. The egg helps the ricotta mixture set as it bakes.

Sausage topping: spread the meat mixture over the ricotta and finish with the remaining mozzarella and Parmesan. Divide the filling as evenly as you can so the halves cook at a similar pace.

Checking texture and timing

Bake at 200°C for 22–25 minutes, then use the tip of a knife to check the courgette. It should pass in easily; if it still feels firm, continue baking and check again shortly.

The total listed time is 40 minutes, but ovens and the size of the courgettes can affect how quickly they become tender. Watch the topping as well: it should be melted and lightly coloured.

Serving the boats

Warm the reserved marinara and serve it on the side for spooning over the boats. A green salad or simply dressed vegetables add freshness alongside the rich sausage and cheese filling.

For a fuller meal, serve with bread to catch extra sauce. Let the boats rest briefly after baking so the filling is easier to serve.

Recipe notes & tips

• Choose courgettes of a similar size so they are likely to become tender at the same time.
• Leave a sturdy border when scooping so the boats hold their shape.
• Drain excess fat from the browned sausage before adding the marinara.
• Divide the ricotta and sausage mixtures evenly among all six halves.
• Check tenderness with a knife near the end of the baking time.
• Warm the remaining marinara separately for serving.

Variations

• Use spicy sausage: Leave out the optional chilli flakes for a gentler filling.
• Make it with poultry: Use ground turkey or chicken and season it with the listed homemade-sausage spices.
• Add fresh herbs: Stir chopped basil into the filling after it comes off the heat.
• Change the cheese: Use all part-skim ricotta or all whole-milk ricotta, as preferred.
• Serve with grains: Add cooked rice or another grain on the side for a more substantial meal.

Common mistakes to avoid

• Scooping too deeply: Leaving less than the stated ⅓-inch border can make the boats fragile; keep a sturdy layer of flesh.
• Skipping the fat drain: Excess sausage fat can make the filling oily; drain it before adding the sauce.
• Using a cold, firm filling: Simmer the tomato mixture as directed so the purée blends in before assembly.
• Overfilling unevenly: Divide the mixtures among all the halves so each boat cooks consistently.
• Relying only on the timer: Courgette size varies; use the knife test and bake until it slides in easily.

How to store

Refrigerate cooled leftovers in an airtight container for up to 3 days. Reheat in a 180°C oven until hot throughout, or microwave individual portions; the courgette may soften further after reheating.
