1
Preheat oven to 375 F.

Prepare water for pasta and cook the noodles according to package directions, shaving 1-2 minutes off of cooking time since pasta will continue to cook in the oven.
-
3
Heat a medium saucepan over medium-high heat.

Add butter and wait for it to melt.

Pour in milk, then the beer, and whisk constantly until it thickens just a bit.
-
8
Stir in cheeses and whisk until melted, about 3-5 minutes.

9
Turn heat down to medium-low and continue to stir occasionally, letting the mixture cook for 5-6 minutes to thicken and settle a little.

10
After 6 minutes, stir in the seasonings.

One the pasta finishes cooking, drain it, then pour it into a casserole dish (I used a large oval baking dish) that youve coated with cooking spray.
-
12
Pour cheese mixture over the top and toss well to combine.
-
13
Add fresh spinach, then sprinkle panko bread crumbs on top.
-
14
Bake for 30 minutes or until bubbling and the noodles and bread crumbs are golden in color.
