Green Bean Casserole From Scratch

Green Bean Casserole From Scratch | Buttered Side Up
Green Bean Casserole has actually never played a huge part in my family’s Thanksgiving meal. Which is a shame, because it’s delicious.

But until last week, I had never attempted making it. It seemed like one of the those dishes that was hopelessly processed. I mean, store-bought French fried onions are the epitome of processed, right? And most recipes I knew of called for canned soup as well. Not exactly the most nutritious side dish.

This year I was on a mission to tackle this Thanksgiving staple and make something less processed. I was going to fry my own French onions if I had to. 
After looking over The Faux Martha’s recipe, I noticed that she mentioned that she got her French fried onions from Trader Joe’s. So when my sisters and I took a trip to the cities, I kept my eye out for them. I actually found some at IKEA, and the list of ingredients was quite short: onion bits, palm oil, wheat flour, water, and salt. Certainly not a health food, but it wasn’t going to kill me if I so much as looked at it. So I snatched up a can.
I must admit that even as I was making this casserole, I wasn’t so sure that it was going to be fabulous. But one bite put my fears to rest. The creamy, hearty sauce is amazing, the onions on top are so so yummy, and the green beans make you not feel so bad for eating this dish. Heh heh. 

This recipe is pretty heavy on the mushrooms and fried onions (mua-ha-ha-ha). If you want a higher ratio of green beans to mushrooms or onions, simply double the rest of the ingredients and leave the amounts of mushrooms or onions the same.

If you’d like to make this recipe completely from scratch, you can make the fried onions yourself: HERE and HERE are some recipes. And HERE is a gluten-free option.

DO AHEAD: You can make the green bean cream sauce and keep it in the refrigerator for about 3-5 days. Bake in preheated oven for 25-30 minutes. Sprinkle the fried onions on top in the last 10 minutes or so of baking time.

I made this last night to "practice" for Christmas. :) It was absolutely delicious! I made my own fried onions: I tossed 2/3 c sliced shallots (no egg or buttermilk) with some flour and seasonings and fried them in a little bit of avocado oil. Delicious!
