"Great recipe! Thank you:)"
With the holidays approaching, a green bean casserole is one of the most loved side dishes. So, let's eliminate the can of soup and get a better, fresher version of this holiday classic without that soup.
While green bean casserole is mainly served at Thanksgiving, it also goes perfectly with casual dining, like meatloaf or take-it-to-take-dish parties.
👨🍳How to Green Bean Casserole with Mushroom Soup
Preheat the oven to 350° convection or 375° conventional.
If you are using fresh green beans, clean and trim. Then, 5 minutes in boiling water with some salt. One teaspoon of salt per quart of water is fine.
Chop one small onion. Add two tablespoons of butter to a large skillet over medium-high heat. Add onion and cook until clearing some, about 2-3 minutes.
Stir in two tablespoons of flour until smooth, and cook for two minutes. Remove from heat.
Add 1 teaspoon salt, ½ teaspoon black pepper, 1 teaspoon sugar, and 1 cup sour cream. Mix well. Stir in about 2 pounds of green beans and 1 cup of shredded cheese of your choice. Cheddar cheese is commonly used, but Colby Jack, Gruyere, or Swiss cheese are good choices.
Transfer the bean mixture to a 2 ½ quart casserole dish. Top with the remaining 1 cup of cheese. You can cover at this point and refrigerate to cook for 1-3 days. Do the topping at the time of cooking.
Crush 12 Ritz crackers to make ½ cup of crumbs. Melt 1 tablespoon of butter in a microwave, then mix the butter with the crushed crackers. You can use a cup of French fried onions added in the last 5 minutes of cooking.
Sprinkle your topping over the casserole.
Bake for about 35-40 minutes until the top is golden and the casserole is bubbly.
For more details, keep reading. See the Recipe Card below for complete instructions and to print.
Green bean options
This recipe works fine with fresh, frozen, or canned green beans. You may use French-cut or straight-cut beans. Frozen or canned beans are just dumped and go, so I gave instructions to use fresh, but use what you want.
Cooking Fresh Green Beans: You can not just put fresh green beans in the casserole. They need precooking, or they may not cook thoroughly. I suggest boiling them. Bring the water to a boil and cook for five minutes.
🧀About making the sauce
In this recipe, we are thickening with a traditional roux— the traditional and relatively simple way to thicken things. Use butter and flour to make a roux, then add cheese and sour cream. For more discussion on creating a roux, see How To Make Gravy at Home.
Why no can of soup? Cans of soup are used in casseroles and crockpot cooking to thicken things and sometimes add flavor. But for that, you are adding a lot of chemicals and flavors that I don't enjoy.
Cheese choices
Nice cheddar cheese is commonly used and provides a great classic taste. But any cheese will be fine, like Colby Jack, Gruyere, or Swiss cheese(my choice).
Topping options
Now, we are into the passionate part of green bean casserole. Everybody has their favorite topping.
I suggest a topping of crushed butter crackers (Ritz) mixed with butter. Again, it is a break from tradition for many but a great and easy topping.
If you want the traditional can of French fried onions, leave off the cracker topping, then cook as directed, but add 1 to 1 ½ cups of French fried onions for the last five minutes of cooking.
The third option is Panko breadcrumbs. Mix 1 cup of Panko breadcrumbs with 2 to 3 tablespoons of melted butter. You can add ¼ cup of grated Parmesan to the bread crumbs if you want. Add the breadcrumb mixture at the beginning of cooking the casserole.
Pan size choice
A full-size recipe is perfect in a 2 ½ quart casserole dish, and the topping is set for that size. You can use a 9 by 13 casserole, but it is larger, so the casserole will be thinner, and you will want to increase the topping by about 50% to cover the larger area.
A half-size recipe fits a 1-quart casserole dish, or use an 8 by 8, 6 by 9, or an 8 or 9-inch round dish. You may need some adjustments to the amount of topping.
⬇️How to make this a "for two" friendly recipe
Since this is generally a large family holiday recipe, I have set the amounts and instructions to 8 servings. But it is an easy recipe to cut in half if you want.
- Use the recipe card and adjust the number of servings to four.
- Use the amount of ingredients in the ingredient list, not the instructions—those do not adjust.
- It will fit in a 1-quart dish, but use what you have available. Cooking time will be about the same, but watch the top color.
- Cooking time will be about 10-15 minutes shorter—watch the top color.
How to make green bean casserole ahead and cook later
Make the casserole but without topping, and do not cook. Cover tightly and refrigerate for 2-3 days. Add topping and cook when needed.
Serving
This casserole is known as an All-American Thanksgiving side dish. Serve with Roasted Turkey Breast, Sausage Stuffing, and Sweet Potato Casserole. See Thanksgiving Recipe Roundup for all the recommendations.

Recipe Notes
Pro Tips
- First, never cook a new recipe for the first time for an important meal. Do a test run a week or two ahead.
- This is an easy recipe to cut in half. Use a small casserole dish—about 1 quart. Cooking time will be about the same. Watch the color of the top. More instructions in the recipe post.
- Many prefer canned beans, but use the beans of your choice. I prefer fresh, but frozen or canned will do. Note that it will take about 3 cans of drained green beans to be 2 pounds of beans.
- Most will want cheddar cheese, which is fine, but I love Swiss cheese here.
- I think you should try the Ritz cracker topping, but if you really want the traditional can of French-fried onions, that should work fine. Leave off the crackers and cook as directed, but add the onion rings for the last five minutes of cooking.
- Instructions for bread crumb topping in the post.
- A great make-ahead dish. Do up to mixing the topping. Then you can cover and refrigerate for 1-3 days. Create and use the topping just before cooking.
- Leftovers are good in the refrigerator for about three days.
Your Own Private Notes
To adjust the recipe size:
You may adjust the number of servings in this recipe card under servings. This does the math for the ingredients for you. BUT it does NOT adjust the text of the instructions. So you need to do that yourself.

Wonderful alternative to the standard recipe.I had trouble with a too thick sauce so added enough milk to make it creamy. Did anyone have trouble cleaning the pan once the sauce was made…Swiss cheese mess?
Lauren says
I’ve been searching other green bean casserole recipes, I really want to try this one! What do you think about substituting the sour cream for cream cheese?!
DrDan says
Hi Lauren,
Welcome to the blog.
When creating a recipe post, I usually read many recipes. There were a few that used cream cheese. I don't remember now which but they are out there.
Having said that. I'm not a fan of cream cheese in casseroles or things like chili or southwest recipes. And my wife (who liked this recipe) will ask what I did and then not eat it. So, it is a matter of individual taste.

Heather says
Two tablespoons of butter dried up in 2 seconds and left my flour in crumbles? There's no way that's all the liquid that can be used.
DrDan says
Hi Heather,
Sorry, it didn't work well for you. The usual ratio of flour to fat for a roux is 1:1 and that is what this is. You can increase the butter (double) if you wish.
My best guess of what happened to you is the butter used was your issue. The butter should be real butter with full fat. Many butter substitutes are whipped or have a lower amount of fat.

Elisabeth Wasslen says
I would love to try this, but cannot do dairy. Can I just ask, what kind of soup were you using in the original recipe? I am a big vegetable lover, and so is my family, and I think we would all enjoy this. Thank you in advance.
DrDan says
Hi Elisabeth,
Welcome to the blog.
If you are lactose intolerant, I know there is lactose-free sour cream available. I hear there are dairy free versions but I have never seen them. Of course, there are dairy free subs for butter and cheeses.
The original recipes for this use Campbell's Cream of Mushroom soup which does have milk products. I don't know of substitutes that are dairy free unless you want to make your own.
This recipe is just so dairy heavy, it seems hard for you to do. Can I interest you in bacon? I have an excellent green bean bacon recipe that we use for special meals. https://www.101cookingfortwo.com/baked-bacon-green-beans/
Sorry I'm not more help.
Dan
Elisabeth Wasslen says
Thank you. I so much appreciate your help. Usually I use unsweetened coconut beverage and coconut yoghurt, e.g. I am also allergic to wheat, egg white and soy so I am always looking for good things I can eat. Actually I can eat very old cheddar cheese without consequence. I will definitely try the green beans with bacon. Looks so good to me.
Sandra says
Another winner. I used Swiss cheese and Ritz crackers. Yummy. The second day it had thickened up a bit so I would suggest a thinner sauce if making ahead
DrDan says
Thanks Sandra, I have never done this one "make ahead" so great tip.

DrDan says
Hi Krissy,
No, I have not. But I would expect a little downgrade with frozen. I have tried both in other recipes and the texture and flavor seems to suffer just a little.

KrissyG says
Thank you, Dan! We'll go with fresh green beans... making this week. :)
KrissyG says
Great recipe! Thank you:)
Wondering if anyone has tried frozen green beans yet... We'd love to know of/about the taste, texture, etc.
DrDan says
I don't do nutrition info due to the many variables. But if you want an estimate then check at https://www.caloriecount.com/cc/recipe_analysis.php.
About the frozen beans. I suspect some texture issues with the things I have done before with frozen beans. But give it a try and report if you would please.

DrDan says
Thanks for the notes and rating. We had it for Thanksgivings and I used cheddar. Good but I like the Swiss cheese a little more.

Hi, Dan.
Did a "trial" run of this yesterday making sure it was at least liked by all (I was going for loved by all but a solid like would have made it tested and family approved). I, as well could never wrap my head around the other GB Casserole and can't even swallow whatever those things called onions were/are. So when I saw this it was a must try mainly for my husband who has missed this dish he grew up on solely because I would not make it (and I didn't grow up on it my grandparents refused to make it thank goodness!). Just for FYI I used fresh green beans.
Well the votes are in. Two liked it and two loved it! Sold! I gave some to my empty nester next door neighbors and one said this is pretty good the other said I love this version!
Thank you for an alternative to that other stuff. This dish will be on our holiday dinner table tomorrow.
Tracey
PS... I'm sure it's user error but once again can not get the stars to work. Would you so kindly give it 5 stars for me if you can?
Tracey says
Just an update... one of the nurses my husband has worked with for years got sick and went home. We know them well so I sent over two dinners for them. Thought nothing more about it until the phone rang and Chris (the hubby) said two things. One was to let me know that the macaroni and cheese I made was out of this world (funny thing about that was it was a last minute add on for the kids. Simplistic made on the stove top with 4 ingredients. I had never made it before, but it will be made again. A LOT!). The other comment was on your GB casserole! He said that if he had to choose between the meat and one of those dishes he would no doubt have had a vegetarian dinner! Ha! Just thought I'd let you know how much it was enjoyed along with my "not on the menu Mac and cheese"! Haha
Hope you had a wonderful and blessed Thanksgiving day and meal.
