STEP ONE: Preheat your oven to 375 degrees F and grease a 9X13 baking dish with butter or cooking spray.

STEP TWO: Heat a large skillet over medium heat, then add the olive oil, the green beans, and a pinch of salt. Cook beans until they turn bright green and begin to soften, usually about 5 minutes. Transfer to the baking dish.

STEP THREE: Use the same skillet over medium heat to melt the butter and cook the garlic until fragrant, about one minute. Add the flour to the skillet, whisking until a paste is formed and continuing to cook for an additional minute.

STEP SIX: Bake the casserole for 8-10 minutes before adding the fried onions and baking for an additional 8-10 minutes. Your casserole is ready when the onions are golden brown, and the beans are tender.

Can You Use Frozen Green Beans Instead of Fresh?

I highly recommend fresh green beans if available, but this recipe can easily be adapted to canned or frozen green beans. 

  • Canned: You’ll want 3 cans (14.5 oz) total for green bean casserole without cream of mushroom soup. Be sure to drain them thoroughly, then add them straight to the baking dish without cooking first.
  • Frozen: For frozen green beans, 3 (10 oz) bags should do the trick. Omit step 2 and increase your baking time to 15-17 minutes before you add the fried onions. 

How Do You Make Green Bean Casserole Less Watery?

The roux is the secret key to thickness in this green bean casserole without mushroom soup. It is made from all-purpose flour, a natural thickener. 

If you find that your sauce is coming out too runny, be sure that you are using enough flour and add more if needed. Cornstarch is another thickener you can use if you are in a bind.

Variations on Green Bean Casserole Without Mushroom Soup

It is simple and easy to make this green bean casserole no mushrooms recipe exactly how you’ll like it. Use these simple guidelines for help:

  • Cheese – Add 1 ½ cups of fontina, swiss, gruyere, cheddar, or your favorite cheese while adding the cream cheese. 
  • Bacon – Crisp up 6 slices and set them aside. Use the bacon grease in the skillet instead of the olive oil to sautee your green beans. Chop up the bacon and add it to the top of the casserole along with your onions. 
  • Oil – Feel free to use your favorite neutral-flavored cooking oil instead of olive oil.
  • Toppings – Fried onions are best, but if you don’t have any on hand, you can use cornflakes or crushed butter crackers to top off your casserole.

How Do I Store Leftover Green Bean Casserole?

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 6 months.

  1. Hi,

    To use 3 pounds green beans, do I need to double the sauce or maybe 1.5 times the sauce ?

    Also I cooked 2 lb fresh green beans in the pan for 15 min. Then baked according to instructions. Baked again 20 min longer.The green beans was NOT cooked at all. Maybe I should have steamed it?

    • Hi Farrah, the green beans will do most of their cooking on the stove, so it’s important to ensure they are softening before being baked in the oven. Green beans can take longer to cook in a pan if they are very crowded. You can steam them, but I like the taste of them better when they are sauteed on the stove. I would use a larger pan or even cook them in batches.

      3 pounds of green beans would be doubling the recipe, so I would just double everything else in the recipe as well. It will take longer to bake in the oven as there is more food.

    • Hi Farrah, I have not made this one ahead of time as of yet, but I would cook the sauce and beans and keep them separate and add them together right before baking. It will take longer to cook from refrigerated since everything is colder.

  2. Hands down the flippin best green bean casserole without mushroom soup I have ever made. It was a hit, no leftovers, not even for me! I used the can bed beans, I’ll try fresh again very soon.
    Smooth, creamy, de- lish!
    Thank you!

  3. My family loved these green beans. It was a nice change from using the canned mushroom soup. I’ll never go back. I fried sliced shallots to top it off. Delicious!
