Just because spaghetti squash is a healthy substitute for real-deal pasta doesn’t mean it should pale in comparison. Nuanced tomato sauce and meaty mushrooms are a perfect match for tender, buttery squash. We’d argue that this vegan spaghetti squash with mushroom marinara sauce would make any Italian grandma proud.


1 spaghetti squash, halved and seeds removed

4 tablespoons extra-virgin olive oil, divided

Kosher salt and freshly ground black pepper

1 pint cremini mushrooms, sliced

2 garlic cloves, minced

1 tablespoon chopped fresh thyme

2 teaspoons chopped fresh rosemary

2 cups marinara sauce

4 tablespoons nutritional yeast


1. Preheat the oven to 400°F. Line a baking sheet with parchment paper. Brush the inside of the squash with 1 tablespoon of the olive oil; season with salt and pepper.

2. Place the squash cut side down on the baking sheet. Roast until fork-tender, 35 to 40 minutes.

3. While the squash cooks, heat the remaining 3 tablespoons of olive oil in a medium skillet over medium heat. Add the mushrooms and sauté until browned and tender, about 5 minutes. Add the garlic and sauté until fragrant, about 1 minute. Stir in the thyme and rosemary; season with salt and pepper and transfer to a plate.

4. Add the marinara sauce to the skillet and cook over medium-low heat until warmed through, about 5 minutes.

5. Remove the squash from the oven and shred it with a fork. To serve, top the squash with marinara sauce, mushrooms and nutritional yeast.
