Ingredients for green bean casserole recipe.

Just 5 Ingredients

  • Green beans – we use canned French Style green beans.
    • Want to use fresh green beans? Use 3-4 cups of fresh, cut green beans. You just need to trim the ends first, and if they are large, cut them in half to ensure tender green beans. For more info, check out our Fresh Green Bean Casserole recipe.
  • Cream of Chicken & Mushroom Soup – You can also use just cream of mushroom soup or just cream of chicken soup but we like the combo better.
  • Milk – Use at least 2% milk or use half and half for a creamier texture.
  • French’s Fried Onions – If your family does not like fried onions, you can used crushed Ritz crackers or even Panko breadcrumbs toasted in butter.

How to Make Green Bean Casserole

It’s beyond easy to make. Just follow these 3 simple steps:

  1. COMBINE. Mix green beans (be sure to drain them thoroughly), soup, milk, salt and black pepper in a large bowl (you can use garlic salt for added flavor).
  2. POUR. Pour the green bean mixture into a 9×13 baking dish.
  3. BAKE. Bake for 18-20 minutes. Top with crispy onions and bake for an additional 5 minutes. Serve warm.

  • More Flavor. Add in some sliced mushrooms, chopped onions or any other spices for added flavor.

  • MAKE AHEAD. To save yourself even more time, assemble your casserole 24-48 hours in advance, and keep it covered in the fridge. Be sure to add the fried onions right before baking, otherwise they’ll get soggy.
  • STORE. If you end up with leftovers after your holiday dinner, store them in an airtight container in the fridge for up to 3 days.
  • REHEAT. Preheat the oven to 350°F. Cover with foil and bake for about 15 minutes per pound. Remove the foil and bake for additional 10 minutes. If the french fried onions need to be a little more crispy, broil on low for 2-3 minutes. You can also microwave to reheat.

Green Bean Casserole Recipe

By: Lil’ Luna
This green bean casserole recipe is a classic side dish at holiday meals! It's simple, delicious, and requires only 4 ingredients!
Servings: 10
Prep: 5 minutes
Cook: 25 minutes
Total: 30 minutes


  • 3 (14.5-ounce) cans French-style green beans drained
  • 1 (10.5-ounce) can condensed cream of chicken soup
  • 1 (10.5-ounce) can condensed cream of mushroom soup
  • ¼ cup milk
  • salt and pepper to taste
  • 1 (2.8-ounce) can French-fried onions


  • Preheat the oven to 350°F.
  • In a large bowl, mix green beans, soups, milk, salt and pepper and pour into a lightly greased 9-x-13-inch baking dish.
  • Bake for 18–20 minutes. Top with onions and bake for 5 minutes more.



Make ahead of time. Assemble your green bean casserole through Step 2 up to 48 hours in advance and keep it covered in the refrigerator. Be sure to wait to add the fried onions until the last 5 minutes of baking, otherwise, they will get soggy.
Slow cooker directions. Lightly spray the slow cooker with cooking spray. Combine green beans, soups, milk, salt, and pepper in the slow cooker. Cook on low for 2–3 hours, or on high for 1 hour. Meanwhile, bake fried onions in a 350°F oven for 5 minutes. Transfer green beans to a serving dish and sprinkle with fried onions.
To use fresh green beans. Use 3–4 cups trimmed, halved green beans instead of the canned beans. Fresh green beans are more crispy, but if you like the softer texture found in canned green beans, you can pre-boil them first for 7–8 minutes. If using a slow cooker, cooking time may be longer with fresh green beans.

  1. I made this for my family Thanksgiving, and no one like it.!!
    It tastes like soup and green beans. I would use maybe two cans green beans and one can Chicken soup if i ever made it again. and half of the Frenchs onions. Better yet, will probably sick to Frenches recipe.
