Tessa’s Recipe Rundown
Taste: The addition of cheese and bacon PLUS homemade extra-creamy sauce (instead of that canned condensed stuff) all takes this casserole to a whole new level of deliciousness.
Texture: Creamy, crisp, crunchy, cheesy, satisfying.
Ease: Very simple to make. You can refrigerate the unbaked, untopped casserole for a couple days if you want to make ahead for Thanksgiving.
Pros: So much more fun and tasty than regular green bean casserole.
Cons: None!
Would I make this again? I make this casserole every holiday season.

Cheesy Green Bean Casserole with Bacon is about to be the most crowd-pleasing side dish on your Thanksgiving table.
It’s officially one of the most delicious months of the year! Between November and December, I really can’t choose which has the best food.
Not just holiday food, but hearty, soul-warming soups like Pot Pie Soup, rich, decadent pies like Caramel Apple Streusel Pie, and cozy, flavorful cookies like Brown Butter Pumpkin Chocolate Chip Cookies. I love every minute of it.

How to Make the BEST Green Bean Casserole Recipe
The Fried Onions
While the rest of this Green Bean Casserole is homemade, I could not find any easy alternatives to the fried onion topping. But what would green bean casserole at Thanksgiving be without those crispy fried onions?! You should be able to find French’s brand crispy fried onions at your local supermarket, but you can otherwise grab them online here.
How to Make Tender Green Beans
- Blanch the fresh green beans in boiling water for about 4 to 6 minutes.
- Strain into a large bowl filled with ice water to stop the cooking.
- Drain, dry, and proceed with the recipe.
Can You Use Frozen Green Beans For Green Bean Casserole?
Yes! Just thaw before using.
Can You Add Mushrooms to This Green Bean Casserole?
Yes! You can add in 3/4 pound of cleaned, sliced bella or button mushrooms. Add in with the onions and proceed with the recipe as written.
Can I Skip the Bacon?
If you need to make this recipe vegetarian, feel free to experiment with skipping the bacon and using a couple tablespoons of butter or a splash of oil to sauté the onions and garlic. You may need to melt an additional tablespoon of butter to make the roux.
Can I Use Heavy Cream Instead of Milk?
Sure, just note that you’ll get a richer, thicker, and creamier texture.
Can You Use Almond Milk in this Green Bean Casserole?
While I haven’t tried this myself, readers have reported success using unsweetened almond milk in this recipe. Just note that the final texture won’t be as rich and creamy.
Can You Double This Recipe?
Yes! Simply double all the ingredients and bake in two 9×13-inch baking pans.
Can You Make Green Bean Casserole Ahead of Time?
Absolutely! Here’s how:
- Once the casserole is assembled but just before baking, cover and refrigerate for up to 2 days.
- Top with shredded cheese and fried onions before baking.
- If baking straight from the fridge, add a few minutes to the baking time.
If you need to make this casserole further ahead, I’ve included tips for freezing and baking from frozen just below.
Can You Freeze Green Bean Casserole?
Yes! Assemble the casserole in a heat-safe and freezer-safe pan, but don’t top with the shredded cheese or fried onions yet. Wrap the pan in plastic wrap. Cover with tin foil, label, and date. Freeze for up to 4 months.
To bake, remove plastic and foil. If using a glass or ceramic pan, allow to defrost overnight in the fridge. Top with shredded cheese and fried onions before baking. Bake for about 45 minutes from frozen.

Ingredients
- 4 strips bacon, diced
- 1 medium yellow onion, finely diced
- 2 cloves garlic, minced
- 3 tablespoons flour
- 1 cup whole milk*
- 2 tablespoons sour cream
- Freshly ground black pepper, to taste
- 1 pound green beans, ends trimmed and cut in half
- 1 cup shredded sharp cheddar cheese
- 1 cup French’s French Fried onions
Instructions
- Preheat the oven to 350°F.
- In a medium skillet set over medium heat, add the bacon. Cook, stirring often, until most of the fat has rendered and the bacon is beginning to crisp. Add the onions and cook until soft and translucent, about 4 minutes. Add the garlic and cook for 1 minute, stirring. Using a slotted spoon, remove the mixture to a paper towel-lined plate, leaving the bacon drippings behind.
- Sprinkle the flour over the bacon drippings and whisk to combine. Cook for 1 minute, whisking constantly. Gradually whisk in the milk, then add the sour cream and bacon mixture. Stir until the mixture has thickened to gravy consistency. Remove from heat and season with black pepper to taste.
- Bring a large pot of water to a boil and salt generously. Add the green beans and cook until tender but still crisp and green, about 5 minutes. Drain immediately then shock in a bowl of ice water to stop the cooking. Drain again and pat dry.
- In a large bowl, combine the bacon mixture with the green beans, tossing to coat. Spread evenly in a greased 9 by 13-inch baking pan.
- Make ahead: At this point, you can cover the pan and refrigerate the unbaked, untopped casserole for up to 2 days.
- When ready to bake, top with shredded cheese and fried onions. Bake for 30 minutes, or until golden brown.

This is amazingly delicious! My daughter brought a pan of this for Thanksgiving one year, it’s now a family favorite! Thank you for sharing!
Delicious! For anyone interested – works great with Gluten free swaps – I use King Arthur 1:1 GF flour. And Gluten free fried onions (best I’ve found are from Fresh Thyme – think brand name is Amy’s).
Do you only top it with the cheese, or do you mix a little in the gravy mixture?
Hi Amanda! Feel free to experiment with adding some cheese to the gravy, but we’ve only tried this casserole per the recipe instructions, just topping with the cheese. Let us know how it goes if you give it a try 🙂
I made this on Saturday but forgot to get the bacon, so I used a pound of ground chicken instead. It was SO good! I also forgot to grease the pan and salt the boiling water (I was a little frazzled from Thanksgiving). But it was so satisfying, and fresh green beans made all the difference. I thought we’d have enough to last us a week but it lasted 2 days. I’m going to make it again today and try it with a tube of breakfast sausage. Thanks a million!
I’ve made this every Thanksgiving for the past five years. Every year everyone claims they don’t like green bean casserole, try this and say it’s SO good lol! I joke that I just reconvert everyone into green bean casserole lovers every year. Thanks so much for this deliciousness!
I’m in a pickle, can canned green beans be used,and how much?
Thank You
Margaret
Hi Margaret, that should be fine (frozen is better if you can, just thaw before using), but I honestly can’t say how many cans you’d need as we haven’t tested that, just make sure the green beans equal 1 pound.
Temperature setting was left out.
Hi Terri! Do you mean the oven setting? “Preheat the oven to 350°F” is listed as the first sentence in the directions of the recipe 🙂 Please let me know if you’re looking for another temperature setting. Thanks!
This is a staple at our holiday meals every year. My boys fight over the leftovers. Thank you for all or your fabulous recipes
So happy to hear that! Thanks for letting us know, Dawn 🙂
I absolutely love this recipe. Been using it for yearss ever since I found it. It has literally been a godsend as I cannot eat regular green bean casserole due to a mushroom allergy. Thank you so much. My husband loves it better than the regulat one since I introduced him to it. I have found my family loves to use maple bacon instead of regular for the additional depth of bacon flavoring.
This makes me insanely happy! Thank you so much for the kind words, Amber!
it turned out great!!
I’m so glad to hear that, Rebecca!
So glad to hear that!
So good!!! Everyone always gushes about them when I make it. A little extra work but so worth it!
I made this last year for Thanksgiving. I will be making it again this year with one major change. I will be doubling the recipe. It is so good!
