A Classic Holiday Casserole

I love green bean casserole, it reminds me of holidays from my childhood. This is a version of Campbell’s green bean casserole developed by Dorcas Reilley in the test kitchen (although I do love my from-scratch version too)!

  • This dish needs only 5 minutes of prep time making this the easiest side dish ever.
  • Can be made ahead of time, placed in a baking dish, and baked just before serving.
  • Top with crispy onions or even a Panko mixed with butter and a sprinkle of parmesan cheese.
  • It’s perfect as a Thanksgiving side dish, for Easter or Christmas dinner but it’s also great alongside Sunday supper too.

Ingredients in Green Bean Casserole

Green Beans – For this recipe, you can use fresh, frozen, or canned.

Canned green beans are softer but are easy to use because they require no prep. Simply drain and enjoy.

Frozen green beans require no cutting and have a tender-crisp texture. You can skip cooking frozen green beans but I prefer the texture if they’ve been cooked in boiling water for about 5 minutes (and you’ll need a bit more salt).

Like frozen, fresh green beans have a tender-crisp texture and a fresher flavor. Simmer for 8 minutes.

Sauce – Using a can of condensed mushroom soup is what makes this recipe so easy (and is the base of the creamy mushroom sauce). Any “cream of” soup will work just fine in this recipe or you can use homemade condensed mushroom soup or chicken soup!

Crispy Fried Onions – Crispy Fried Onions (or french fried onions) are essential to this recipe (so much that it’s even sometimes called French’s Green Bean Casserole)!

If you’ve never had them, these onions are delish and great on all kinds of casseroles, burgers, and more! They’re added both in and on this casserole!

Variations

  • I love to add cheddar cheese to this recipe (optional of course!), it melts into the sauce making it extra yummy.
  • Make your own homemade mushroom cream sauce instead of canned and/or swap out the onions for fried shallots.
  • Add minced cloves of garlic cooked in butter, some roasted garlic, or a dash of garlic powder.
  • Simmer the green beans in chicken broth. Reserve the drained chicken broth for making your stuffing!

How To Make Green Bean Casserole

There’s a reason this dish has been around for years, it’s simple. It’s delicious. Perfect in every way.

  1. Cook Beans: Simmer fresh or frozen green beans. (drain them if they’re canned)
  2. Mix Sauce: Combine mushroom soup, milk, soy sauce, and pepper (per recipe below).
  3. Toss Together: Add the sauce, green beans, some crispy onions, and cheese to a bowl.

Set It & Forget It

Green bean casserole can be prepared as above and cooked in a crock pot or slow cooker on low for about 2-3 hours. Once cooked through, turn the slow cooker to warm.

If your slow cooker is larger than 4qt, I would recommend doubling the recipe.

How To Prep Ahead of Time

You can make green bean casserole ahead of time.

  1. Prepare as directed except keep the crispy onion topping in a separate container. I usually place them in a sealed sandwich bag right in the dish and sprinkle on top before baking.
  2. Refrigerate for up to 48 hours.
  3. Remove the dish from the refrigerator at least 30 minutes before baking. If it’s really chilled, you may need to add up to 10 minutes of extra cooking time.

Traveling to Dinner?

If you’re heading to someone else’s house for dinner, do everything except the last 10 minutes of baking and bring it along with you covered in tin foil!
