Instructions
Cream of Mushroom
Melt butter in a skillet over medium-low heat. Add mushrooms and onions and sauté until tender, about 8 minutes. Season to taste with salt and pepper.
Add garlic and nutmeg and cook for 2 minutes. Add flour and cook for an additional 2 minutes. Quickly whisk in cream and chicken broth until smooth. Bring to a boil and boil for 1 minute. Remove from heat. Taste and adjust seasoning if needed–you want it to be saltier than normal, since this is a condensed soup.
Allow to cool before transferring to a jar or freezer-safe container. Once soup is completely cool, you can store it in the refrigerator or freezer.
French Fried Onions
Slice the onions and soak them in buttermilk at room temp for an hour or so.
Whisk together the flour, salt, and pepper in a mixing bowl and then transfer to a plate or shallow dish.
Dredge each onion slice in the flour mixture and then fry in a stockpot of 375 degree oil. Remove with slotted spoon to a paper towel and sprinkle with salt while still hot.
Casserole
Bring a large stockpot of water to a boil and add the beans. Blanch for 5 minutes. Drain and immediately plunge them into an ice bath. Drain again and set aside.
When all elements are complete, mix together all green beans, your condensed soup (don't feel that you have to use ALL of it - add until you get your desired consistency), and half of the french fried onions all together.
Place into a casserole dish or cast iron pan and bake at 475. Bake for 10 minutes before adding the other half of the onions on top. Continue baking a few more minutes and serve warm.
