  • Method: Baking, Roasting
  • Cuisine: American
  • Diet: Gluten Free

Ingredients

  • 1 medium spaghetti squash
  • 1–2 tbsp olive oil
  • 2–3 cloves garlic, minced
  • 5–6 cups fresh spinach (or 10 oz frozen, thawed and drained)
  • 4 oz cream cheese
  • 1 cup shredded mozzarella cheese, divided
  • ¼ cup grated Parmesan cheese, divided
  • Salt and pepper, to taste
  • Optional: red pepper flakes, Italian seasoning, chopped fresh herbs (parsley or basil)

Instructions

  1. Preheat oven to 400°F (200°C). Cut spaghetti squash in half lengthwise and remove seeds.
  2. Drizzle squash halves with olive oil, season with salt and pepper, and place cut-side down on a baking sheet. Roast for 35–40 minutes until tender.
  3. While roasting, heat oil in a skillet and sauté garlic until fragrant. Add spinach and cook until wilted. Season with salt, pepper, and optional red pepper flakes.
  4. Remove from heat, stir in cream cheese until melted, then mix in ½ cup mozzarella and 2 tbsp Parmesan.
  5. Once squash is cool enough to handle, fluff the strands with a fork and mix in the spinach-cheese filling.
  6. Top each squash half with remaining mozzarella and Parmesan. Return to oven and bake for 10–12 minutes until bubbly and golden.
  7. Let cool slightly before serving.

Notes

  • Swap spinach with kale or arugula for variety.
  • Add mushrooms, sun-dried tomatoes, or cooked sausage for extra flavor.
  • Gruyère or sharp cheddar can replace mozzarella for a richer taste.
  • Prep ahead by roasting squash and making filling in advance.
