Green Bean Casserole with Gruyere

This cheesy, rich variation of green bean casserole is perfect for holiday parties and thanksgiving menus. We've replaced the canned cream of mushroom soup with a rich, cheesy mushroom sauce made from scratch. We're using fresh green beans for optimum taste and texture and adding extra cheese on top before baking for richer flavor and taste!

Ingredients

1 lb rinsed and trimmed fresh green beans
2 tbsp unsalted butter
8 oz mushrooms, quartered
cracked black pepper
2 tsp granulated garlic
2 tbsp all-purpose flour
1 cup chicken stock
1 cup half and half
3.5 oz container shredded gruyere, divided
1 ½ cups fried onions

Instructions

  1. Preheat oven to 400 F.
  2. Fill a large pot of water ¾ way with water and a tbsp of salt. Bring water to a boil. Cut green bean ends off and trim them in half. Place green beans into the boiling water for 2-3 minutes to cook them lightly. Remove from the water with a slotted spoon and into a large bowl filled with ice water. Set aside to cool.
  3. Heat a skillet over medium heat. Add the butter, once melted add in the mushrooms and stir together. Cook for 6-8 minutes or until the mushrooms are golden brown. Season with a pinch of kosher salt and cracked black pepper. Turn the heat to medium low and add in the garlic powder and the flour to the mushrooms and stir to combine.
  4. Add in the chicken stock to the mushrooms and bring to a simmer. Once simmering, add in the half and half and stir together. Simmer for an additional 6-8 minutes or until the mixture is thick enough to coat the back of the spoon. Remove sauce from heat.
  5. Add in the 2/3 of the shredded gruyere cheese and ½ cup of fried onions and stir together.
  6. Strain the green beans from the ice bath and blot dry with a paper towel. Add the beans and sauce to an ovenproof casserole dish and stir together until combined. Top the border with the remaining fried onions and remaining 1/3 cheese over the top of the beans.
  7. Bake for 10-20 minutes or until the top is golden brown and bubbly.
