Shake up your Thanksgiving green bean casserole tradition by putting our creamiest green bean casserole ever, inspired by Budget Bytes, on your table! Featuring a homemade mushroom sauce, our contemporary take on this classic comfort food dish will have your holiday guests lining up for seconds — and then asking for the recipe.
Forget that can of cream of mushroom soup that traditional green bean casserole recipes always mention. Instead, impress your guests with a mouthwatering sauce made with fresh mushrooms, butter, and cream cheese. This heavenly homemade sauce transforms plain green beans and crunchy French-fried onions into a surprising gourmet holiday dish.
Fresh mushrooms deliver a depth of earthy flavor to this holiday side dish. Heat olive oil in a large skillet over medium heat. Saute mushrooms and garlic for 7 to 10 minutes or until they are tender, browning slightly, and have released their moisture.
Make the mushroom sauce
Butter and flour create a roux that thickens the liquid components of the sauce. Add butter to the skillet with the mushrooms and stir until it’s melted. Sprinkle flour over the mixture and cook, stirring, until the flour becomes golden in color. Whisk in vegetable broth and simmer until it has thickened. Whisk in the milk and bring to a simmer. Add the chunks of cream cheese and whisk slowly until they have melted completely and the sauce is smooth. Season liberally with salt and pepper to taste.
Combine the green beans and mushroom sauce
Place frozen green beans in a large bowl. Pour mushroom sauce over green beans and stir to combine. No need to thaw or boil the green beans before combining with the sauce because the hot mushroom sauce and the oven will do the cooking for you.
Transfer green bean mixture to a casserole dish and top with fried onions
Pour the green bean mixture into a 2- to 3-quart casserole dish. Scatter french-fried onions evenly over the top of the green beans. The onions add a delightful crunch to contrast with the creamy mushroom sauce and the tender green beans.
Bake the green bean casserole
Slide the casserole dish in the oven and bake at 350 F for 20 to 25 minutes or until the fried onions start to brown slightly. Serve your green bean casserole hot out of the oven.
