Step 1

If you haven't already, cook the pasta until it's al dente (or done to your liking); drain and set aside.

Step 2

Heat oil and 1 tbsp butter in a large, deep skillet over medium heat, then add the onion and sauté for 2 minutes. Then, add the mushrooms and sauté for 4 minutes or until the onions and mushrooms are soft, adding more butter as needed. Last, add the garlic and sauté for 1 minute until it's fragrant.

Step 3

In a small bowl, whisk the salt, flour, milk, nutritional yeast, lemon juice, and dijon together. Then, pour the mixture into the skillet.

Step 4

Reduce heat to medium-low, stirring frequently until the sauce thickens.

Step 5

Add pasta into the skillet and use kitchen tongs to toss everything together, making sure the pasta is coated in the sauce.

Step 6

Divide into bowls, top with black pepper and parsley and enjoy!
