Green bean casserole from scratch is not difficult but it does take some time. We're tossing out the canned cream of mushroom soup and making our own yummy mushroom sauce along with delicious fresh fried onions. Included are steps for prepping this casserole the day before if you will be short on time the day you plan to serve this yummy side dish.
Earlier in the week, I polled my Facebook fans on their favorite Thanksgiving dish. The answers varied, but the majority and most requested dish for a real food makeover was the infamous green bean casserole. I don't blame them. There's just something so comforting about green beans swimming in that creamy mushroom sauce and topped by those flavorful crunchy onions.
Until now I've only ever had green bean casserole made from canned green beans, canned cream of mushroom soup, and canned french fried onions. While delicious, it's DEFINITELY not real food.
What I'm sharing with you today is most definitely the real deal, my friends. No fake food in sight.
I'm not gonna lie, this recipe takes longer than any other recipe I've ever put on the blog. I'm usually a no muss no fuss kinda gal. I like to post quick and easy meals that beginners can even conquer, but sometimes you have to make something a little special. This is not complicated, but it does take longer than the processed food version. Start to finish it took me 1 hour and 15 minutes. If you choose to make this on Thanksgiving, you might want to prep the day before. Instructions below for that step.By prepping ahead, you could make this just as fast as the standard canned version. Pretty sweet if you ask me!
How to prep the day before
- Slice the onions and put in airtight container in the fridge.
- Chop the mushrooms and store in airtight container for the fridge.
- Wash, trim and blanch the green beans the day before.
- If you are going to be very short on time on Thanksgiving, go ahead and make the mushroom sauce the day before and place in a bowl in the fridge for the next day.
- The onions I would leave for the next day because they won't stay fresh.
Assembling the day of
- Dredge the onions in the flour and fry them.
- Mix together the blanched green beans, mushroom sauce, ¼ of the freshly fried onions, and spread into casserole.
- Top with remainder of the fried onions and bake.
