Green Bean Casserole

This Green Bean Casserole features mushrooms and garlic sautéed to enhance flavor, combined with a creamy sauce made from butter, flour, vegetable broth, milk, and cream cheese. Frozen French-cut green beans are stirred in, and crispy fried onions add a crunchy topping, creating a creamy, textured vegetable side dish often served warm.

Description

This Green Bean Casserole begins by sautéing chopped mushrooms and garlic in olive oil seasoned with salt and pepper until the mushrooms are soft and their moisture evaporates. A roux is then made using butter and flour, cooked until slightly golden to form the base for the sauce. Vegetable broth, milk, and garlic powder are added and simmered until the mixture thickens.

Cream cheese is whisked in to melt, enriching the sauce with creaminess and tang. Frozen French-cut green beans are incorporated, warming through to maintain their texture. The casserole is typically finished by topping with crispy fried onions, which add a crunchy contrast to the creamy filling.

This side dish suits holiday meals or everyday dinners and combines familiar ingredients with a creamy mushroom-forward sauce. Using fresh mushrooms provides a deeper flavor than typical canned cream soups, elevating the casserole. Choosing fresh or properly frozen green beans avoids mushiness common with canned beans.

Ingredients

Servings
  • 8 oz. mushroom $2.49
  • 2 cloves garlic $0.08
  • 1 Tbsp olive oil $0.22
  • 3/4 tsp salt $0.04, divided
  • 1/4 tsp black pepper $0.04, freshly cracked, divided
  • 4 Tbsp butter $0.50, salted
  • 1/4 cup all-purpose flour $0.04
  • 1 cup vegetable broth $0.13
  • 1 cup milk $0.18, whole
  • 1/8 tsp garlic powder $0.02
  • 4 oz. cream cheese $0.46
  • 24 oz. green beans $2.36, frozen, French-cut
  • 1 cup fried onions $0.73, crispy, divided

Instructions

  1. Preheat the oven to 350ºF. Roughly chop the mushrooms into small pieces. Mince the garlic.
  2. Add the olive oil to a large skillet and heat over medium. Once hot, add the mushrooms and a pinch of salt and pepper. Sauté the mushrooms until soft, then add the minced garlic and continue to sauté until the liquid in the skillet evaporates.
  3. Add the butter and flour to the skillet. Stir to melt the butter and allow the butter and flour to create a paste that coats the bottom of the skillet. Continue to stir and cook over medium for one to two minutes, or until the flour begins to turn golden on the bottom of the skillet.
  4. Add the vegetable broth, milk, and garlic powder to the skillet. Whisk to combine and dissolve any browned flour off of the bottom of the skillet. Allow the liquid to come up to a simmer, at which point it will thicken.
  5. Add the cream cheese to the skillet and whisk over medium heat until the cream cheese has fully melted into the sauce.
  6. Add the frozen green beans to the sauce and stir to combine. Continue to heat over medium, stirring occasionally, until the green beans have heated through and the sauce comes up to a gentle simmer. Let the green beans simmer for a few minutes. Give them a taste and add salt and pepper to your liking (I added about ½ tsp salt and another ⅛ tsp pepper).
  7. Stir ¼ cup of crispy fried onions into the green bean mixture. Pour the green beans into a 2-quart casserole dish and top with the remaining ¾ cup crispy fried onions.
  8. Bake the casserole for 20-25 minutes, or until the fried onions have turned deep golden brown and the sauce is bubbling up around the edges.

Notes

  • Use fresh mushrooms like Baby Bellas or button mushrooms to add depth to the creamy sauce.
  • Better Than Bouillon broth adds well-rounded flavor and saltiness to the sauce.
  • Fresh or frozen green beans are preferred over canned to avoid mushy texture and muted flavors.
