Scale
For the topping:
- 1 medium onions, thinly sliced
- 1/4 cup all-purpose flour
- 2 cups panko breadcrumbs
- 1 teaspoon kosher salt
- 1 large egg
- 1 tablespoon milk
For the casserole:
- 1/3 stick butter
- 1 cup diced onions
- 1 cup sliced fresh mushrooms
- 2 cups green beans, cleaned and cut into thirds
- 1 cup Randall Great Northern Beans
- 3 cups chicken broth
- 1 can cream of mushroom soup
- salt, pepper and garlic salt to taste
- ¼ cup grated Cheddar
Instructions
- Preheat the oven to 475F degrees. Line a large baking sheet with parchment paper or a silicone baking mat. Set aside.
- Thinly slice the onion. Pour flour in one small bowl, Panko, salt and pepper into a medium bowl, and whisk the egg and milk together in another small bowl. First, dip a few slices of onion into the flour, then into the egg mixture, and finally, dunk them into the Panko and coat them well. Place onto baking sheet. Repeat with the rest of the onions. Bake onions until golden brown, about 25 minutes. Flip them twice during this time. Set them aside. Reduce oven to 400F degrees.
- While the onions are baking, prepare the green beans. Boil the green beans in 2 ½ cups chicken broth for ten minutes and drain.
- Melt the butter in a large skillet. Sauté the onions and mushrooms in the butter. Add the green beans, Randall Great Northern beans, mushroom soup, and salt, pepper and garlic salt, to taste, to the onion mixture. Add ½ cup chicken broth. Sauté until thick 10 mins.
- Pour into a greased 1 1/2-quart baking dish and top with onions and cheddar cheese. Bake for 12 minutes.
