Ingredients

• 500 grams button mushrooms
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 1 medium, diced yellow onion
• 3 cloves, minced garlic
• 2 tablespoons plain flour
• 2 cups vegetable broth
• 1 cup heavy cream
• 1 teaspoon fresh thyme leaves
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 250 grams fusilli or penne pasta
• 1.5 cups, shredded cheddar cheese
• 0.5 cup, grated Parmesan cheese
• 0.75 cup breadcrumbs
• 2 tablespoons, chopped (for garnish) parsley

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.

Step 2

Cook the pasta in salted boiling water until just shy of al dente (about 1-2 minutes less than the package instructions). Drain and set aside.

Step 3

Heat olive oil and butter in a large skillet over medium heat. Add the diced onion and cook until soft and translucent, about 3-4 minutes.

Step 4

Stir in the minced garlic and cook for another 1 minute until fragrant.

Step 5

Add the sliced mushrooms and cook for 5-7 minutes until they release their moisture and turn golden brown.

Step 6

Sprinkle the flour over the cooked mushrooms and stir continuously for 1 minute to coat the mixture and remove any raw flour taste.

Step 7

Gradually pour in the vegetable broth, stirring constantly to incorporate. Let the mixture simmer until slightly thickened, about 2-3 minutes.

Step 8

Reduce the heat to low and mix in the heavy cream, thyme leaves, salt, and black pepper. Cook for another 2 minutes, stirring occasionally.

Step 9

Remove the skillet from the heat and stir in 1 cup of shredded cheddar cheese until melted and creamy.

Step 10

In a large mixing bowl, combine the cooked pasta with the mushroom-cheese sauce. Mix well, ensuring all the pasta is coated.

Step 11

Transfer the mixture into the prepared casserole dish and spread evenly.

Step 12

In a small bowl, combine the breadcrumbs, Parmesan cheese, and the remaining 0.5 cups of cheddar cheese. Sprinkle this mixture evenly over the casserole.

Step 13

Bake in the preheated oven for 20-25 minutes, or until the top is golden and bubbly.

Step 14

Once baked, remove the casserole from the oven and let it cool for 5 minutes. Garnish with chopped parsley before serving.
