5-Ingredient Creamy Green Bean Casserole With Sour Cream
This 5-ingredient green bean casserole is an easy Thanksgiving or Christmas side dish made with fresh green beans, low-sodium cream of mushroom soup, and sour cream. It's creamy, delicious, beginner-friendly, and you can even make it ahead of time!
Ingredients
- 1 lb fresh green beans (ends trimmed and cut into 2-inch pieces)
- 10.5oz can cream of mushroom soup (low-sodium or low-fat is fine)
- ½ cup sour cream
- ¼ cup milk
- 1½ cups crispy fried onions
Instructions
- Preheat your oven to 350°F. Lightly grease an 8x8-inch baking dish.
- Bring a large pot of water to a boil. Add the trimmed green beans and cook for 4–5 minutes. Drain the green beans and set aside.
- In a large mixing bowl combine the cream of mushroom soup, sour cream, and milk. Stir until smooth and creamy.
- Add the drained green beans and ½ cup of crispy fried onions to the mixing bowl. Stir until the green beans are coated evenly in the sauce.
- Transfer the mixture to the baking dish. Bake uncovered for 20 minutes.
- Remove from the oven and sprinkle the remaining 1 cup of crispy fried onions evenly over the top of the casserole. Return to the oven for another 5–10 minutes or until the fried onions are golden brown.
- Let the casserole cool for 5 minutes. Serve and enjoy!
Notes
- Don't overcook the green beans: They'll continue cooking in the oven, so you want them just a bit tender. About 4-5 minutes of boiling does the trick.
- Sauce consistency: If you feel like your sauce is a bit too thick, you can add 1 tablespoon of extra milk at a time in step 4 until you hit your desired consistency. Don't make it too runny though!
- Don't like sour cream? No problem! Just skip the sour cream - the casserole still tastes delicious!
- Don't mix in too many fried onions: I've made the mistake of adding a little too many fried onions in the mixture and it turned out kinda...oniony. Just stick with 1/2 cup of the fried onions for the mixture. Remember, you can always add more on top!
