Ingredients

For the squash

• 1 large butternut squash, halved lengthwise and seeded
• 2 tbsp extra virgin olive oil
• Salt and freshly ground black pepper

For the filling

• 8 oz cremini mushrooms, sliced
• 4–5 cups baby spinach
• 1 small shallot, finely diced
• 2 garlic cloves, minced
• 2 tbsp crumbled feta
• 1/4 cup whole milk ricotta (optional)
• 1/2 tsp dried oregano
• 1 tsp fresh thyme leaves

Cheese

• 1/2 cup shredded mozzarella
• 1/4 cup grated Parmesan

Herbs

• Extra thyme leaves for garnish
• Freshly cracked black pepper

Ingredient Notes

• Best mushrooms: Cremini (baby bella) mushrooms offer the best depth of flavor for roasting. Their firm texture holds up well against the soft squash.
• Spinach choices: Fresh baby spinach is preferred over frozen for this recipe to ensure the filling stays compact rather than watery.
• Cheese: Parmesan provides the salty “umami” punch, while mozzarella offers that iconic melt. If you want a sharper Mediterranean kick, don’t skip the feta—it cuts through the sweetness of the squash beautifully.

Kitchen Equipment

• Large baking sheet
• Parchment paper or aluminum foil
• Large skillet
• Chef’s knife and cutting board
• Spoon (for scooping)

How to Make Mushroom and Spinach Stuffed Butternut Squash

1. Roast the squash: Preheat your oven to 400°F (200°C). Drizzle the cut side of the squash with olive oil and season with salt and pepper. Place cut-side down on a baking sheet and roast for 40–45 minutes until tender.
2. Cook mushrooms: Heat olive oil in a skillet over medium-high. Add sliced mushrooms and sauté until browned—this is key for flavor!
3. Wilt spinach: Add shallots and garlic to the mushrooms, then fold in the spinach just until wilted.
4. Mix filling: Stir in the feta, ricotta (if using), oregano, and thyme.
5. Stuff squash: Flip the roasted squash halves up. Gently scoop out a little flesh if needed to make space. Fill with the mushroom-spinach mixture.
6. Bake: Top with mozzarella and Parmesan. Return to the oven for 10–15 minutes until bubbly and golden.
7. Garnish: Finish with fresh thyme and cracked black pepper before serving.

Chef Tips

• Choosing a ripe squash: Look for one that feels heavy for its size with a matte skin.
• Roast cut-side down: This traps steam, cooking the squash faster and creating a caramelized edge.
• Watery filling: If your spinach releases too much water, sauté it until completely dry before adding to the squash.
• Resting: Allow the stuffed squash to rest for 5 minutes after baking so the filling sets.

Common Mistakes

• Over-scooping: Don’t remove too much flesh; keep the structural integrity of the “boat” intact.
• Skipping the sear: Ensure your mushrooms are golden brown before adding spinach; otherwise, the filling will be bland.
• Using too much cheese: We want a savory vegetable dish, not a heavy casserole. Stick to the suggested amounts.

Variations

• Mediterranean: Add chopped Kalamata olives to the filling.
• Protein: Add cooked chickpeas or lentils to the mixture for extra plant-based protein.
• Vegan: Use nutritional yeast instead of cheese and omit the ricotta.
• Quinoa/Wild Rice: Mix in 1/2 cup of cooked grains to make this a more substantial main dish.

What to Serve With It

This roasted butternut squash with mushrooms pairs beautifully with lighter sides to balance the richness.

• Try a crisp Greek Chopped Feta Salad recipe for a fresh crunch.
• A side of Roasted Mediterranean Potatoes with Feta and Tomatoes makes for a hearty meal.
• Consider a protein like our Spinach and Feta Stuffed Salmon Recipe if you are feeding a crowd with varying dietary needs.

Storage

• Reheating: Microwave in 30-second intervals or reheat in the oven at 350°F until warmed through.
• Freezing: You can freeze the roasted squash boats (without cheese topping) for up to 3 months. Thaw in the fridge before adding cheese and baking.
• Make Ahead: Roast the squash and prepare the filling separately up to 2 days in advance. Assemble and bake when ready to serve.
