Full Ingredients

For the squash boats

• 2 medium acorn squash (1.5–2 lb each)
• 3 tbsp unsalted butter, melted, divided (2 tbsp for initial roast; 1 tbsp for finishing)
• 1/2 tsp fine sea salt
• 1/4 tsp freshly ground black pepper

For the sausage-apple stuffing

• 1 tbsp olive oil
• 12 oz mild Italian sausage, casings removed
• 1 medium yellow onion, small dice (about 1 cup)
• 2 ribs celery, small dice (about 1 cup)
• 1 medium crisp apple (Honeycrisp, Pink Lady, or Granny Smith), 1/2-inch dice (about 1 cup)
• 2 cloves garlic, minced
• 1 tbsp fresh sage, finely chopped (or 1 tsp dried)
• 1 tsp fresh thyme leaves (or 1/4 tsp dried, optional)
• 1 small pinch red pepper flakes (optional)
• 2 cups day-old sourdough bread, 1/2-inch cubes (about 120 g)
• 1/2 cup low-sodium chicken broth, warmed, plus up to 3 tbsp more as needed
• 1 tbsp apple cider vinegar
• 1/4 cup grated Parmesan cheese
• Kosher salt and freshly ground black pepper, to taste

To finish and garnish

• 1 tbsp melted butter (from above, for brushing edges before final bake)
• 2 tbsp grated Parmesan cheese (for topping)
• 2 tbsp chopped fresh parsley
• Fried sage leaves or extra chopped sage (optional)

Step-by-Step Instructions

Step 1: Heat the oven and prep the squash

Preheat the oven to 425°F (220°C). Line a rimmed baking sheet with parchment for easy cleanup. Carefully slice each acorn squash in half from stem to tip. Use a spoon to scoop out and discard the seeds and stringy fibers. Brush the cut sides evenly with 2 tablespoons of the melted butter and season with the sea salt and black pepper.

Step 2: Roast for tender, caramelized boats

Place the squash halves cut-side down on the prepared sheet. Roast until the flesh is fork-tender and the edges have deep golden, caramelized color, 30–35 minutes. If your squash are very large, add 5 minutes. Remove from the oven and use tongs to flip the halves cut-side up to cool slightly while you finish the filling.

Step 3: Brown the sausage

While the squash roasts, heat the olive oil in a large skillet over medium-high heat. Add the sausage and cook, breaking it into small crumbles, until browned and no longer pink, 5–7 minutes. If excess fat accumulates, spoon off all but about 1 tablespoon.

Step 4: Sauté aromatics, apples, and herbs

Add the onion and celery to the skillet with the sausage and cook, stirring, until the onion turns translucent and the celery softens, about 4 minutes. Stir in the diced apple, garlic, sage, thyme, and red pepper flakes (if using). Cook until the apple is just tender but still juicy, 2–3 minutes. Reduce heat to low.

Step 5: Build the sourdough stuffing

Off the heat, fold in the sourdough cubes. Pour in 1/2 cup warm chicken broth and the apple cider vinegar, tossing until the bread is evenly moistened but not soggy—add up to 3 tablespoons more broth if your bread is very dry. Stir in 1/4 cup grated Parmesan. Taste and season with salt and pepper as needed.

Step 6: Fill the boats and bake until golden

Brush the exposed rims and cut surfaces of the roasted squash with the remaining 1 tablespoon melted butter to encourage caramelized edges. Spoon the stuffing evenly into the four squash cavities, mounding it slightly. Sprinkle with the remaining 2 tablespoons Parmesan. Return to the oven and bake until the tops are crisp and lightly browned and the squash is piping hot, 12–15 minutes. If browning too quickly, tent loosely with foil for the last few minutes.

Step 7: Finish, rest, and serve

Let the squash rest 5 minutes so the stuffing sets. Sprinkle with chopped parsley (and fried sage leaves if you like). Serve hot, with extra black pepper. For a saucier finish, drizzle the pan juices or a teaspoon of warm broth around the squash just before serving.

Pro Tips

• Day-old bread is best. If your sourdough is very fresh, cube it and toast on a sheet pan at 350°F (175°C) for 7–10 minutes to dry it slightly.
• Stabilize the boats by shaving a thin slice off the underside of each squash half so they sit flat on the baking sheet.
• Use a firm, tart-sweet apple (like Honeycrisp or Granny Smith) so it keeps texture during baking.
• Moisture control is key: add broth gradually until the stuffing holds together when pressed but doesn’t weep liquid.
• For extra caramelization, position the pan on a higher oven rack for the final 3 minutes or run under the broiler briefly, watching closely.

Variations

• Turkey sausage and Gruyère: Swap in turkey Italian sausage and use Gruyère in place of Parmesan.
• Vegetarian mushroom–white bean: Replace sausage with 8 oz chopped cremini mushrooms and 1 cup cannellini beans; add 1 tbsp soy sauce for umami.
• Gluten-free herb rice: Use 2 cups cooked wild rice blend instead of sourdough; reduce broth to 1/4 cup.

Storage & Make-Ahead

Roast the squash and cook the stuffing up to 1 day ahead; store separately, covered, in the refrigerator. When ready to serve, bring both to room temperature, assemble, and bake 15–18 minutes at 425°F. Leftovers keep 3–4 days refrigerated; reheat, covered, at 350°F (175°C) for 15–20 minutes. To freeze, wrap individual stuffed halves tightly and freeze up to 2 months; thaw overnight in the fridge before reheating.
