16oz brown or white button mushrooms, sliced (about 6 cups sliced)
For garnish: 1 handful fresh parsley, roughly chopped (if have this)
Cook the pasta according to package directions.
In a medium bowl, whisk together the first six ingredients. Set aside.
Melt butter in a large. When hot add the onion and garlic and sauté until the onion turns translucent. Reduce the heat and add the mushrooms. Cook for about 5 minutes until the mushrooms have softened.
Pour in the broth mixture and continue to cook, stir as needed for about 3 to 5 minutes until the sauce thickens.
Add in the cooked pasta and mix to combine. Garnish if desired.
