One Pot Gnocchi with Spinach and Chicken

So easy to make and so good!!

Ingredients:
2 TB salted butter
2 TB all purpose flour
1 1/2 cups whole milk
1 cup regular chicken broth
1/2 tsp nutmeg
1 tsp onion powder
4 cloves garlic, minced
1 lb shredded rotisserie chicken
1 (17.5) oz package potato gnocchi (usually found in the dry pasta aisle; not frozen - I buy these at the dollar store)
2 cups baby spinach leaves
1/2 cup freshly grated parmesan cheese (I use the non fresh version)
kosher salt and freshly ground black pepper

INSTRUCTIONS

Preheat oven to 425F with rack on upper middle position.
In a large and cast iron skillet, melt the butter over medium heat. Add flour and whisk constantly for 3 minutes until a smooth roux is formed. Whisk in milk and chicken broth until incorporated. Simmer and whisk constantly until slightly thickened, 5 minutes. Whisk in nutmeg, onion powder, garlic, and kosher salt/ground pepper to taste.
Add shredded chicken, uncooked gnocchi, and spinach to the mixture. Stir gently until well coated through, 30 seconds. Sprinkle parmesan evenly over the top and bake in oven about 15-20 minutes or until sauce is bubbly at around the edges and gnocchi is tender. If desired, broil 2-3 minutes to further brown the top.
