Gnocchi with Chicken, Mushrooms, and Spinach in a White Sauce

2 Tablespoons butter
2 Tablespoons flour
1 1/2 cup whole milk
1 cup chicken bone broth
1/4 teaspoon nutmeg
4 cloves minced garlic
salt and pepper to taste
8 oz thinly sliced baby bella mushrooms
meat from 1 rotisserie chicken
1 (17.5 oz) package gnocchi
2 cups baby spinach
1/2 cup grated parmesan

Preheat oven to 425.  In an oven-proof deep skillet or dutch oven, melt the butter over medium-low heat.  Whisk in flour until smooth and slightly browned (about 3 minutes).  Whisk in milk and bone broth.  Whisk and simmer 5 minutes until slightly thickened.  Whisk in nutmeg, garlic, salt, and pepper.

Stir in mushrooms, chicken, gnocchi, and spinach.  Sprinkle with parmesan and bake about 15-20 minutes, or until bubbly and the gnocchi is tender.
