Green bean casserole with cheddar cheese is a slight tweak to an old fashioned dish that takes it to a whole new level of YUM! I mean cheese makes everything better and this is yet another win for dinnertime. For the best outcome we use frozen vegetables, you’ll never go back after a bite of this one.

Cheesy Green Bean Casserole with Frozen Green Beans

If you choose to make this into an Easy Green Bean Casserole with Bacon style, just include 1/4 cup of chopped precooked in with the soup. I do like to add a bit of meat depending on what I am serving this with. If I’m serving turkey I may leave it out. Warmed up it is great with some diced leftover ham in it too.

I do not add cheese when making our Instant Pot Green Bean Casserole because it can stick and cause the burn notice to turn on. This one is really better baked in a baking dish instead. That way you can get the top golden brown too so it’s nice and melted all the way across.

You could transition our Slow Cooker Green Bean Casserole into this one, but it wouldn’t brown on the top. In that case you technically can transfer the Crock into the oven under broil just for a few minutes to fix that but to me that is just more work. If I add the cheese it goes in the oven I say, period.

Ingredients

  • 2 c frozen green beans
    • if you use fresh green beans I would blanch the green beans first for 1-2 minutes, then into an ice bath
  • 1 c mushrooms sliced
  • Butter
  • 1 can cream of mushroom soup, or cream of chicken soup works fine too
  • 1/2 c fried onions divided
  • 1/3 tsp salt and pepper
  • Worchestershire sauce
  • 1 c sharp cheddar cheese

You could choose a different type if you wanted to. Monterey jack can give it just a bit of a kick with a tad of spicy heat. Parmesan has less lactose in it for those with dairy free requirements. If you have someone at home who needs an alternative version, use dairy free cheese and this condensed soup mix.

Which is better, frozen or canned green beans for green bean casserole?

That depends on whom you ask and the texture of the dish you want. If you want beans that keep their shape and have a bit of “chew” to them when done you should use frozen or fresh. In the case that you want them to be very soft and cook a bit faster then canned works. I prefer fresh or frozen.

How do you make green bean casserole not soggy?

Use frozen or fresh beans to begin with, that will not be as mushy or soggy when done. Add fried onions to the top about 10 minutes before it’s done to add a bit of a crunch to the top layer which will also give you more texture to the dish.

This one uses a square 8×8 or 9×9 inch dish. If you have more people coming over you could double this and use a 9×13″ dish instead. Spray the inside with non stick spray so you don’t loose any of it to sticking on the sides. It saves well too for the next day, we will talk about that a bit later.

How to Make Green Bean Casserole with Frozen Green Beans and Cream of Mushroom Soup

  • Preheat the oven to 360 F.
    • oven to 350 degrees works too if you are cooking other items at that temp at the same time, just add a couple minutes
  • Fry the mushrooms in butter for 5-7 minutes on the stove, stirring occasionally.
  • Add the frozen green beans to a bowl, as well as the sautéed mushrooms and 1/4 cup of crispy onions.
  • Add shredded cheddar cheese (2/3 cup) and mushroom soup.
  • Mix thoroughly and transfer the mixture to a sprayed square casserole dish.
  • Bake for 20 minutes.
  • Sprinkle on top the remaining cheese and remaining French fried onions on top and bake for another 10 minutes.

Tips – Gently fold everything together so that the more delicate items don’t break apart completely. Especially with the canned onions you want those to stay as whole as possible to add texture to the inside and top of the dish. Full instructions in recipe card below which can be printed as well.
