This easy, classic, creamy green bean casserole is a Thanksgiving favorite. It goes together in minutes using canned green beans, mushroom soup and loads of crunchy fried onions. Creamy, salty, crunchy deliciousness that pairs perfectly with turkey and all the fixins’. Of course, it’s a tasty side dish for dinner any time of year too.

Thanksgiving wouldn’t be complete without the classic green bean casserole. And now that we’ve got the roasted turkey, stuffing, mashed potatoes and my favorite sweet potato casserole out of the way, it’s time for the vegetable dish to take center stage. This creamy Green Bean Casserole is so easy to prepare and has been a tradition in our home for longer than I can remember. I don’t think I could ever leave it off the Thanksgiving table or I would feel that something was missing.

Yes, you can make this casserole from scratch with homemade soup and fried onions but, with all the other Thanksgiving dishes to get on the table, making this simple casserole can take a lot of stress out of the preparation. This classic version, using premade off-the-shelf ingredients, is easy and the taste is just as yummy as mama used to make. Of course, there’s always a way to make it your own, like using fresh green beans, changing up the soup flavor or using a new flavor of fried onions. Check out the variations I’ve shared below that are still easy but let’s you put your own spin on this side dish.

Tips & Variations

  • Fresh Green Beans – Using fresh green beans is always an option. Just trim the beans, wash and place in a bowl with one tablespoon of water. Place in microwave, cover with paper towel, and cook 5-7 minutes to blanch. Drain and pat dry then add to casserole as you would canned green beans. By the way, the thinner french green beans work best. If using frozen, microwave just long enough to thaw, open package, drain and pat the beans dry. 
  • Soup flavors – Tired of the same old, same old, mushroom soup? Try making it with cream of celery, cream of chicken, cream of potato or even cream of bacon.
  • Cheese lovers – Like cheesier casseroles? Just add 1 cup of cheddar cheese to the green bean mixture.
  • Flavored fried onions – Something I tried this year, change up the flavor of the fried onions. I used the new white cheddar version and it was awesome! They also have a jalapeno, red pepper and a caramelized onions versions too.
  • Meat lovers – If you’re a meat lover, try adding a half cup of cooked crumbled bacon to the green bean mixture. Why? ‘Cause everything’s better with bacon!
  • Make it spicy – Add a dash of heat by flavoring the green bean mixture with a teaspoon or two of cajun seasoning or just add a touch to the top of the casserole by sprinkling it with some crushed red pepper or diced jalapenos.
  • Gluten-free version – use Sprouts or Aldi’s Simply Nature gluten-free fried onions, a gluten-free mushroom soup or make your own sauce with directions in recipe notes.
  • Make ahead – Want to make ahead of time? Up to two days ahead, put the casserole together up to the baking stage, cover with plastic wrap and store in refrigerator. Take out about 30 minutes before cooking and bake as directed, adding the remaining fried onions on top when indicated.

Notes

Gluten-Free/Dairy-Free Green Bean Casserole option

--------------------------------------------------------------------------------------------
To make your own fried onions instead of canned, slice a large onion into thin slices and toss with rice flour. Shake off excess. Place 1/2" vegetable oil in skillet, heat over medium-high heat and, when the tip of an onion ring sizzles, place a handle full of onion slices in oil and crisp up. Repeat with all remaining onion slices then set on paper towel to drain off excess fat. Let cool and use in place of canned fried onions.
----------------------------------------------------------------------------------------
To make your own mushroom soup and leave out the condensed soup and milk in the recipe above, combine 2 T. olive oil, 1 small chopped onion and 1/2 teaspoon minced garlic in a skillet and saute for 5-6 minutes. Add in 8-oz. chopped white mushrooms and a little more olive oil as needed. Cook another 3 minutes then stir in 1-3/4 cup of plain almond or coconut milk and a pinch of thyme and bring to a boil. Whisk in a thickening paste of 2 Tablespoon cornstarch and 1/4 cup almond or coconut milk. Stir continuously for 1 minute then reduce heat and let simmer for 5 minutes. Season to taste with salt and pepper.
Continue to assemble and cook as stated above.
