Instructions

Roast the Squash:
Preheat oven to 400°F (200°C). Slice squash in half lengthwise and scoop out seeds. Drizzle with olive oil, season with salt and pepper, and place cut-side down on a baking sheet. Roast for 35–40 minutes until fork-tender.
Prepare the Filling:
Heat 1 tbsp olive oil in a skillet over medium heat. Sauté onion for 5 minutes, then add garlic and cook for 1 more minute. Add cherry tomatoes and cook until softened. Stir in lentils or meat, marinara, and Italian seasoning. Simmer 5–10 minutes.
Assemble:
Flip roasted squash halves cut-side up. Use a fork to loosen squash strands. Divide filling between the halves, mixing slightly with the squash. Top with mozzarella cheese.
Bake Again:
Return to oven and bake for 10–15 minutes, or until cheese is melted and bubbly.
Garnish & Serve:
Let cool slightly. Garnish with chopped parsley or basil and serve directly from the squash shells.

Notes

Use cooked chickpeas or plant-based crumbles for a vegan version.
Swap mozzarella for cheddar, provolone, or feta for a cheesy twist.
Add mushrooms, bell peppers, or spinach to bulk up the veggie content.
