This savory Green Bean Casserole is made with a homemade creamy mushroom sauce and topped with crispy onion rings for a side dish to remember!
How did rolling the clocks back go for you? I can tell you that the fall time change is pretty brutal when you have early birds. My boys were up at 4am that first day! At least I went to bed early the night before, so it wasn’t as bad as it sounds. I’m sure we’ll all adjust soon enough.
When you wake up early, it is nice to not have to wait until 7:30am for the sun to come up. It’s hard to spring out of bed when the sun won’t be shining for hours.
I actually really like this time change once we’re settled into it because the early sunset makes me finally feel like fall is here. The boys and I suddenly feel like we have a nightlife when it’s dark at 5pm since that’s about as late as we’re ever out. I’m also excited to think about the upcoming holidays, especially the feast that is Thanksgiving.
Do you cook the same things year after year for Thanksgiving or change it up? We have our standards like turkey, dressing, roasted vegetables, cranberry sauce, and green bean casserole, but sometimes I try making them in different ways.
I think this green bean casserole is going to be the winner for this year’s turkey day. The sauce is made from scratch instead of the good ol’ cream of mushroom soup version (although I love that classic one too!), and the crispy onion rings on top are way better than canned fried onions.
You could add diced chicken to this casserole to make it a full dinner, serve it as a side for a holiday meal, take it to a potluck, or just have it on the side any time of year. Whenever you decide to enjoy this green bean casserole, I hope your family loves it!

- Preheat oven to 375 degrees F. Spray a 9 x 13" baking dish with cooking spray.
- In a large skillet, melt butter over medium heat. Stir in mushrooms and garlic, and saute for about two minutes. Stir in flour until smooth. Stir in milk about ¼ c. at a time, stirring constantly to avoid lumps. Add half and half, salt, and pepper to taste. Bring to a simmer.
- Stir in cheese until melted. Stir in frozen green beans, and transfer mixture to prepared baking dish. Arrange onion rings over the top, and bake in preheated oven for 30-40 minutes. Press onion rings down into the casserole a bit about halfway through baking. Casserole is done when it is bubbly and onion rings are golden brown.
You can use all milk instead of milk and half and half if you prefer, but the sauce won't be quite as rich.

This is a great recipe. I transformed it into vegan which is generally easy for many if not most non-vegan recipes. I also trimmed down the baking time by simply pot heating the mushroom mix, dumping into the casserole dish with the onions on top and then baking just a few minutes until browned (maybe 5). The mushroom gravy/soup is simply wonderful. Thanks…

Is there a good way to prepare this the night before or morning of Thanksgiving? I want to take it to our gathering but will be traveling 2-1/2 hours and I don’t want to take up valuable cooking space in the host’s kitchen to prepare it at her house.
Sammy Garcia says
Do you have to use half and half?
vanesss says

one of my favorite recipes ever
Mel Raschke says
Such a good idea. I am saving this for Christmas Eve.
Mel Raschke says
Such a great idea with the onion rings. Not cooking Thanksgiving dinner this year, but will use this for Christmas Eve.
Melissa says
“Onion ring topping” is one of the most beautiful sentences I’ve ever heard.
Andi Gleeson says
Haha thanks, Melissa! Glad you like it :)
Brittany B says
This is such a good idea! Onion rings are the best. I’m definitely pinning this one.
Andi says
Thanks a lot, Brittany! Hope you had a nice weekend :)
Jennifer Edsall says
How would you adapt this to use fresh green beans? THANKS
Andi says
Hi, Jennifer. Sorry it took me a couple days to get back to you! Usually fresh and frozen beans cook similarly, but this recipe uses french cut beans. If you want to take the time to cut fresh beans that way, you could keep the recipe the same. If you want to use kitchen-cut green beans, you might want to lightly steam them first so they don’t turn out too crisp. Hope that helps!

I was SOOO ready for the clocks to change! I hate waking up in the dark! Onion rings on green bean casserole!? Why have I never thought of this?! Genius!
Andi says
I like the time change except for the insane waking hours of my precious children. Hopefully they’ll adjust soon! Thanks about the casserole, Justine :)
Annie @Maebells says
This is so fun! I love the twist with onion rings on top, why has this not been done before! Genius!
Andi says
Thank you, Annie! Unfortunately the onion rings aren’t GF, but maybe you could make your own :) Whole Foods might have some GF onion rings! I’m going to check.
Kristine @ Kristine's Kitchen says
4 am? Oy! My kids slept till about 6:15, instead of their usual 7:15, which I can totally handle. I hope yours adjust to the time change soon! I love how you made homemade mushroom sauce for your casserole, and that is just brilliant to top it with onion rings!
Andi says
Today they made it to 5am, so I think we’re moving in the right direction! 7:15 sounds heavenly to me. Thank you, Kristine!
Jamie | Jamie's Recipes says
ONION RINGS! Brilliant!! I always eat the fried onions off first anyway so making them giant onion rings seems like the most natural progression for me. I can’t wait to try this!
Andi says
Thanks a lot, Jamie! I think you’ll love it this way!
Julie @ This Gal Cooks says
Why have I never thought to do this? Onion rings > French Fried Onions. Great recipe, Andi!
PS, I love the extra hour in the day but hate that it’s dusk when I leave work!
Andi says
Thanks so much, Julie! Maybe you can leave work earlier since it will seem like night at about 4:45 soon :)
Sara @ Bitz & Giggles says
Oh my, Andi. Green Bean Casserole is one of my favorite sides of ALL TIME. The fact that you put onion rings on top is pure genius. Pinning and sharing!
Andi says
Thank you so much, Sara! I appreciate it!
Jen @ Yummy Healthy Easy says
Oh my, Andi. You are so creative! What a great use of frozen onion rings! I love this version of green bean casserole. I’m going to have to try this soon, I can’t wait until Thanksgiving!
Andi says
Thank you, Jen! I’m so excited for Thanksgiving too!
Jaren (Diary of a Recipe Collector) says
Yummo! I have such a weakness for onion rings and Green Bean Casserole is always my favorite side dish!! I can’t wait to try this one!
Andi says
Thank you, Jaren! Maybe you can try it this way this year :)
Carol at Wild Goose Tea says
What a wonderful enhancement to this tried and true recipe. I am liking it. If this doesn’t show up on the holiday table, there are some unhappy diners. So what a good way to change it up a bit.
Andi says
Thank you, Carol! Your Thanksgiving must be so fun because YOU’RE there! :)
Gina says
Holy SMACKERS!!!!!!!!! I could eat this whole thing – YUM!!!!!
Andi says
Haha you are so cute, Gina. Thank you!
