Spinach Smoked Mac and Cheese

I got a bunch of organic spinach from the Full Circle Farm delivery and I was thinking what I can do with it outside of preparing it as a salad. Finally I thought I can put it into mac and cheese.

So I went to Trader Joes, and was looking at their cheeses, and I was impressed that they carry raw milk cheese and grass fed cow cheese.
I decided to make this mac and cheese with a twist, so I used a smoked Gouda as part of the cheese mix. You can also add goat cheese if you like.


Ingredients
3 Tablespoons unsalted butter
1/2 cup finely minced sweet onion
1/3 cup all-purpose flour
4 cups whole milk
kosher salt & freshly ground black pepper, to taste
4 cups spinach leaves, cut into 1/2-inch strips
1 cup shredded Sharp White Cheddar Cheese
1 cup shredded Smoked Gouda
3/4 pound penne, cooked

Directions
1. In a large saucepan, melt butter over medium heat. Add onion and saute until softened, about 5 minutes. Whisk in flour until mixture is golden. Add the milk, whisking constantly. Raise heat to medium-high, bring to a boil and continue to whisk until sauce is smooth and thickened, 10 to 12 minutes. Add a sprinkle of salt and pepper.

2. Add spinach to sauce; give it a few stirs until spinach is wilted. Stir in cheeses until melted and well combined. Add cooked pasta and stir. Taste and add more salt and/or pepper, if desired. Serve immediately.
