Oven Fried Guinness Onion Rings with Stout Gravy

For the onion rings:
In a casserole dish, place sliced onions and cover with 2 cups buttermilk and beer. Cover dish with foil and put in fridge for at least 5 hours or for better results overnight.

Preheat oven to 450ºF. Remove onions from fridge and set aside. In a large bowl, combine flour, paprika, and half the salt. In another bowl, mix together remaining buttermilk and eggs. Take half of the flour mixture and add it to the buttermilk and give it a good whisk. In another large bowl, combine panko, cornmeal, and remaining salt.

Spray two baking sheets with nonstick cooking spray. Take an onion slice, dip into the flour, then the buttermilk, and then the panko. Place on baking sheet. Repeat with remaining onion slices. Bake onions for about 15 to 20 minutes, flipping midway. Bake until crispy. Garnish with parsley and serve gravy alongside.

For the stout gravy:
Preheat a sauce pan to medium heat. Melt butter. Add the flour and begin to whisk creating a roux. Let the flour cook out for a minute. Add the chicken stock and stout. Continue to whisk until thickened, about 5 minutes. Remove from heat.
