Ingredients
For the Squash:
- 2 medium acorn squash, halved and seeded
- 2 tbsp olive oil
- Salt and pepper, to taste
For the Filling:
- 1 tbsp olive oil
- 1 small onion, diced
- 2 cloves garlic, minced
- 3 cups fresh spinach (or 1 cup frozen, thawed and drained)
- 1 cup cooked quinoa (or rice, for a heartier version)
- ½ cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- ¼ tsp crushed red pepper flakes (optional)
- Salt and pepper, to taste
For the Topping:
- ½ cup shredded mozzarella or Italian cheese blend
- Fresh parsley or thyme, for garnish
Instructions
- Preheat and Prepare Squash
Preheat your oven to 400°F (200°C). Slice each acorn squash in half and remove the seeds. Drizzle each half with olive oil, then season generously with salt and pepper. Place the halves cut-side down on a parchment-lined baking sheet. - Roast the Squash
Roast for 25–30 minutes, or until the flesh is tender and easily pierced with a fork. Once done, flip the halves over and set aside to cool slightly. - Cook the Filling Base
Heat olive oil in a skillet over medium heat. Add the diced onion and cook until translucent, about 3 minutes. Stir in the minced garlic and cook for another 30 seconds until fragrant. - Add Spinach and Quinoa
Add the spinach to the skillet and cook until wilted (or heated through, if using frozen). Stir in the cooked quinoa and season with salt, pepper, and red pepper flakes if desired. - Add Cheese and Creaminess
Remove the pan from heat. Stir in mozzarella and Parmesan until melted and creamy. The mixture should hold together nicely. - Stuff the Squash
Spoon the filling evenly into each roasted squash half, gently pressing down to pack it in. - Top and Bake Again
Sprinkle extra cheese over the top of each stuffed half. Return to the oven and bake for an additional 10–15 minutes, until the cheese is bubbly and golden brown. - Serve Warm and Garnish
Garnish with fresh parsley or thyme before serving. Enjoy your stuffed squash hot from the oven — the perfect cozy meal for chilly nights!
