Green Bean Casserole

Recipe courtesy of Good Samaritan University Hospital 
Serves 6

Ingredients

  • 2 (12 oz.) packages frozen French-cut green beans
  • 8 ounces cremini mushrooms, quartered
  • 3 tablespoons butter
  • 1 small onion, halved and thinly sliced
  • 1 tablespoon fresh parsley, chopped
  • 2 tablespoons all-purpose flour
  • 1/2 teaspoon lemon zest
  • 1/2 teaspoon salt
  • 1 pinch ground black pepper
  • 1/2 cup milk
  • 1 cup sour cream
  • 1/2 cup shredded cheddar cheese
  • 1 (2.8 oz.) can canned French-fried onions

Directions

  • Preheat the oven to 350 degrees.
  • Place green beans into a saucepan and fill with about 1/2 inch of water.
  • Bring to a boil and steam until beans are tender but still bright green, about 5 minutes. Drain and toss with the mushrooms. Set aside.
  • Melt the butter in a large skillet over medium heat. Add the onion and parsley. Cook and stir until onion is tender.
  • Whisk in flour until blended, then mix in the lemon zest, salt, and pepper.
  • Gradually whisk in milk, stirring constantly, so that no lumps form.
  • Stir in sour cream.
  • Warm over medium heat until the sauce begins to bubble. Mix in the green beans and mushrooms, stirring to coat.
  • Remove from heat and toss briefly with some of the cheddar cheese and French-fried onions, saving some of each to sprinkle over the top. Spoon into a 1 1/2-quart casserole dish and top with the reserved onions and cheese.
  • Bake in the preheated oven until the cheese melts, about 15 minutes.
