Why You’ll Love This Green Bean Casserole

Quick and Simple for Busy Holidays

The recipe uses just a handful of ingredients and takes less than 10 minutes to prepare. It’s ideal when you’re juggling turkey, pies, and other Thanksgiving recipes.

Creamy, Crunchy, and Crowd-Pleasing

The creamy mushroom base hugs the tender green beans, while the crispy onions on top provide the perfect savory crunch. Every bite tastes like home.

A Classic That’s Easy to Customize

From adding cheese and bacon to using different soups, this casserole welcomes your personal touches without sacrificing its charm.

Ingredients and Easy Substitutions

What You’ll Need

• 2 (15-ounce) cans cut green beans, drained
• 1 (10.5-ounce) can condensed cream of mushroom soup
• ¾ cup milk
• 1 (2.8-ounce) can French-fried onions, divided
• Salt and black pepper to taste

Ingredient Notes

Canned green beans give that signature texture and flavor, but you can use frozen (thawed and drained) or even fresh green beans if blanched briefly. Campbell’s cream of mushroom soup is the original choice, but you can go with a low-sodium or organic brand if preferred. Whole milk provides the creamiest result, though 2% also works well.

Smart Substitutions

• Use cream of celery or cream of chicken soup if you don’t love mushrooms.
• For a dairy-free version, use a plant-based milk and vegan mushroom soup.
• Gluten-free? Use gluten-free cream soup and crispy shallots instead of fried onions.

Step-by-Step Instructions

How to Make Green Bean Casserole

1. Preheat your oven to 350°F (175°C).
2. In a 1.5-quart casserole dish, combine the drained green beans, condensed soup, milk, and half of the fried onions. Mix well.
3. Bake uncovered for 25 minutes or until hot and bubbly.
4. Remove from the oven, sprinkle the remaining onions on top, and return to the oven for 5 more minutes.
5. Let it rest for a few minutes before serving. Season with salt and pepper to taste.

Tips for the Best Green Bean Casserole

Get That Perfect Crunch

Don’t mix all the fried onions into the casserole. Save half for the topping and only add them in the final minutes of baking to keep them crispy.

Don’t Skip the Rest Time

Letting the casserole sit for 5 minutes after baking allows the sauce to thicken and makes serving easier.

Make It Ahead

You can assemble the casserole a day in advance. Just cover and refrigerate without adding the final layer of onions. When ready to bake, bring to room temperature and follow the last steps.

Holiday Table Presentation
