Green Bean Casserole from Scratch

I have always been a fan of the idea of green bean casserole. I mean who wouldn't be? Fresh green beans swimming in a savory mushroom sauce with crunchy onions on top? Sounds pretty good when it's put that way, huh? Unfortunately, being a scratch girl, not only do I never have canned cream of mushroom soup on hand, I am not a big fan of it's commercial taste. The use of frozen green beans over canned was an automatic; there was no debate there at all.

Last week I decided to make my own green bean casserole, from scratch. What that means is simply making a homemade sauce versus opening a can. It's pretty quick and easy, and boy was it good! I'm going to make it again later this week for the big day. Here's how it goes...

Green Bean Casserole from Scratch
Yield: 8-12 servings

3 TBS butter
1 medium onion, diced
8 oz baby bella mushrooms, diced
1/4 cup cream sherry
1/8 tsp garlic powder
1/2 cup flour
1 tsp salt (or to taste)
1/4 tsp pepper
4 cups whole milk, warmed
2 1/2 lbs frozen cut green beans, cooked and drained
1 1/2 cups french fried onions

Preheat the oven to 375° F. Melt butter in a deep skillet. I prefer using a stainless pan so I get better browning on the bottom, leading to a richer flavored sauce. Add the onions and cook over medium high heat until translucent and starting to caramelize. Add the mushrooms and cook until they are tender and browned. Add the sherry and stir vigorously to deglaze the pan and lift up all the browned bits on the bottom of the pan.

Mix the flour, salt, pepper, and garlic powder together. Add to the skillet and stir to mix. Slowly add the warmed milk, stirring as you go to minimize lumps. Once all the milk is added, cook, stirring continuously until it just comes to a boil and is thick. It will thicken more as it bakes and then cools. Add the green beans and stir to coat. Pour the mixture into a greased 9x12x1 inch baking dish (or similar). Sprinkle the top evenly with the french fried onions. Bake at 375° F until bubbly through and the onions are nicely browned, about thirty minutes. Cool slightly before serving.


  1. I've been wanting to try a homemade green bean casserole lately! Is cream sherry an ingredient that is easy to find?


  2. Hi Emily! Cream sherry is often available in the wine section of larger grocery stores or in liquor stores. It is typically fairly cheap. I think I've usually spent less than $8 for a 750 mL bottle. Be aware there is both a cream sherry and a dry sherry. Both will work fine, but in this application, I prefer the cream sherry as I think it's a little more mellow. Have a great Thanksgiving!
