There are so many green bean casserole variations! This version is very decadent with the added cheese. If you are looking for a green bean casserole recipe without cheese, you can check out my other version.

I don’t know where I saw a cheesy version, probably on facebook. I had to give it a try since I love trying new recipes and well, cheese makes anything better. I think this cheesy version would be great with ham or turkey.

Below is what the casserole looks like before adding the remaining French fried onions. How do the French fried onions get toasty in the crock pot you ask? They don’t. I gave the French fried onions quick sauté in a dry skillet, then sprinkled them over the casserole.

Another option is to put the crock pot insert in the oven for about 10 minutes to give the onions some color, or you can be completely lazy and put them on the casserole right of the container, I actually think they taste just fine this way!

Have you started shopping for your holiday dinner? My fridge and pantry are stuffed to the brim. Not only do I have Thanksgiving dinner to worry about, my daughter Lola is turning 8 that same weekend. I am making her a big Garfield cake with fondant icing. I hope you have a good Thanksgiving!

Classic green bean casserole with cheese!

Ingredients 
 

  • 10.5 oz. can cream of mushroom soup (do not add water)
  • 1/3 cup milk
  • 1/8 tsp. pepper
  • 58 green beans, (Four 14.5 ounce cans green beans) drained
  • 6 oz. container French fried onions, divided
  • 2 cups cheddar cheese, divided

Instructions 

  • Add the cream of mushroom soup, milk and pepper to the slow cooker. Stir until smooth.
  • Add the green beans, half the French fried onions and half of the cheese. Stir.
  • Sprinkle over remaining cheese.
  • Cover and cook on HIGH for 2.5 hours.
  • You have 3 options for the remaining French fried onions. You can add them without crisping to the top of the casserole. Or place the crock pot insert with the French fried onions on top of the green beans in a 350° degree oven for about 10 minutes until crisp. Or put the French fried onions in a skillet and toast them until golden brown (this is what I did), then sprinkle them over the casserole.
  • Serve and enjoy.
  • You can set the slow cooker to warm for your holiday gathering.

    How do I make this with velveeta cheese

    1. Sarah Olson says:

      Cube a small block of velveeta into the recipe. Stir before adding the french fried onions.

  2. GM says:

    I’m doubling this recipe and not sure it will fit in the slow cooker. Can I cook in oven? Degrees how long ?

    1. Sarah Olson says:

      I did not test this in the oven, I apologize. You can double this recipe in the slow cooker and it will just need about an hour longer (maybe less).

  3. Dennis buhr says:

    Is that correct you only use one half of milk.

    1. Sarah Olson says:

      Yes, you can add a touch more if you think it needs it. Most green bean casseroles don’t add much milk.

    5 stars
    We didn’t have cream if mushrooms so we substituted with cream of chicken! It tasted geeat

  5. Colleen says:

    Can I make this with fresh green beans? If so how much would I need?

    1. Melissa says:

      I am wondering the same thing did you try it? If so how long did you cook it or did you use the same recipe

  6. Sara says:

    I can’t wait to make Thanksgiving! Would canned or frozen green beans be okay to use?

    1. Sarah Olson says:

      Yes! will work fine either way.

  7. Kaitlin says:

    Would it be okay to double this? and how much additional time would you recommend?

  8. Karla M Curry says:

    This was really good! Although I used three bags of frozen green beans (mostly thawed) and made my own condensed soup with 1/4c butter + 1/4c flour + 1/2c broth + 1/2c almond coconut milk. Whole family loved it! Will make again!
