- 3 tablespoons olive oil
- 2 tablespoons butter
- 300g (10 oz) blue oyster mushrooms, cleaned and roughly chopped
- 3 cloves garlic, minced
- 1 small onion, finely chopped
- 5 cups fresh spinach (about 150g), roughly chopped
- Salt and freshly ground black pepper to taste
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- For the béchamel sauce:
- 4 tablespoons butter
- 4 tablespoons all-purpose flour
- 3 cups (720ml) milk (whole milk preferred)
- 1/4 teaspoon ground nutmeg
- Salt and freshly ground black pepper to taste
- 3/4 cup grated Parmesan cheese
- For assembly:
- 2 cups shredded mozzarella cheese

Instructions
- Preheat the oven:
- Preheat your oven to 375°F (190°C).
- Cook the pasta:
- Bring a large pot of salted water to a boil. Cook the pasta until just al dente, according to the package instructions. Drain and set aside.
- Prepare the mushroom and spinach mixture:
- In a large skillet, heat the olive oil and butter over medium heat. Add the onions and cook until they become translucent, about 3-4 minutes.
- Add the garlic and cook for another minute until fragrant.
- Stir in the blue oyster mushrooms, cooking in small batches to prevent overcrowding in the pan. Cook for 5-7 minutes until they're browned and any liquid has evaporated. Separate mushrooms batches into a large bowl when they are finished cooking. Season with salt, pepper, and thyme.
- TIP: Don’t season your mushrooms with salt till the very end to keep them from releasing too much water.
- Add the chopped spinach into the bowl of hot mushrooms, stir and allow the heat to wilt the spinach.
- Make the béchamel sauce:
- In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until it forms a roux.
- Gradually add the milk, whisking continuously to avoid lumps. Cook for 5-6 minutes until the sauce thickens.
- Stir in the ground nutmeg, salt, and pepper to taste. Remove from heat and mix in the grated Parmesan cheese.
- Combine the pasta and sauce:
- In a large bowl, mix the cooked pasta, mushroom and spinach mixture, and béchamel sauce until well combined.
- Assemble the dish:
- Transfer the pasta mixture to a greased baking dish. Sprinkle the shredded mozzarella and extra Parmesan evenly on top.
- Bake and broil:
- Bake in the preheated oven for 25-30 minutes, until bubbly and heated through.
- Switch the oven to broil on high and cook for an additional 2-3 minutes until the cheese is golden and bubbly.
- Garnish and serve:
- Let it cool for a few minutes, then garnish with chopped fresh parsley if desired. Serve warm.
Notes: Can easily be made vegan if you substitute the dairy for their vegan alternative!
