Classic Green Bean Casserole With Cheddar Cheese And Fried Onions Recipe

I bring out this Traditional Green Bean Casserole – Feels Like Home™ and watch plates come back spotless as guests quietly demand seconds.

I adore this green bean casserole because it hits every savory note I crave at the table. I love the way sharp cheddar cheese folds into the beans, melting into pockets of salty, tangy creaminess.

And those French fried onions on top, crispy, salty, impossible to ignore, turn each forkful into a contrast of textures. I’m obsessed with the nostalgia of familiar flavors that still feel unapologetically bold.

But mostly I return to this dish because it disappears fast, because people hover, because seconds are never an afterthought. Seriously.

It’s the side dish that steals the meal every single time.

Ingredients

• Fresh green beans: bright snap and color, makes the dish feel homey and fresh.
• Canned green beans: easy shortcut, softer texture but still comforting and quick.
• Condensed cream of mushroom: creamy backbone, it’s cozy and keeps everything saucy.
• Milk: loosens the mix, makes it silky; add more if you want it runnier.
• Sour cream or Greek yogurt: tangy creaminess, basically makes it richer and smoother.
• Sharp cheddar: punchy, salty melt that gives cheesy comfort in every bite.
• Onion or shallots: sweet bite and a little chew, they brighten the whole dish.
• Soy or Worcestershire sauce: deep umami hit, it’s subtle but worth adding.
• Garlic powder: easy garlic boost, no chopping, just steady savory flavor.
• Black pepper: little peppery bite that wakes up the creaminess.
• Kosher salt: seasons everything, go light if you used canned beans.
• French fried onions: crunchy, salty topping that you’ll crave for texture contrast.
• Butter: adds richness and helps those onions crisp up golden.

Ingredient Quantities

• 2 pounds fresh green beans, trimmed and halved (or 2 cans 14 to 15 oz each green beans, drained)
• 1 can (10.5 oz) condensed cream of mushroom soup
• 1/2 to 1 cup milk (start with 1/2 cup, add more if you want it looser)
• 1 cup sour cream or plain Greek yogurt (optional but makes it creamier)
• 2 cups sharp cheddar cheese, shredded
• 1 small onion, finely chopped or 1/2 cup shallots, thinly sliced (optional)
• 1 to 2 teaspoons soy sauce or Worcestershire sauce (adds depth, use to taste)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon black pepper
• 1/2 teaspoon kosher salt, or to taste (less if using canned beans)
• 1 1/2 cups French fried onions, divided (about 1 cup in the casserole and 1/2 cup for topping)
• 2 tablespoons unsalted butter, melted (to toss with onions or dot on top)

How to Make this

1. Preheat oven to 350°F and grease a 9×13 inch baking dish or a similar sized casserole dish.

2. If using fresh beans, blanch 2 pounds trimmed and halved green beans in boiling salted water for 4 to 5 minutes until bright green and just tender, then shock in ice water and drain well. If using canned, drain both cans and pat dry with paper towels.

3. In a large bowl stir together 1 can (
10.5 oz) condensed cream of mushroom soup, 1/2 cup milk (add up to 1 cup later if you want it thinner), 1 cup sour cream or plain Greek yogurt if you want it richer, 1 to 2 teaspoons soy sauce or Worcestershire (start with 1 tsp and taste), 1/2 teaspoon garlic powder, 1/2 teaspoon black pepper, and 1/2 teaspoon kosher salt (use less if you used canned beans). Mix until smooth.

4. Fold the drained beans into the sauce, then stir in 2 cups shredded sharp cheddar cheese and the optional finely chopped small onion or 1/2 cup thinly sliced shallots. Make sure the cheese is evenly distributed.

5. Transfer the bean mixture to the prepared baking dish and spread it out evenly. If it looks too thick, stir in a little more milk, a tablespoon at a time, until you like the consistency.

6. Toss about 1 1/4 cups of the French fried onions with 2 tablespoons melted butter, then fold about 1 cup of that mixture into the casserole so you get crunchy bits inside.

7. Sprinkle the remaining 1/2 cup fried onions on top, and dot a few extra spoonfuls of melted butter over the top so they brown nicely. You can also add a little extra shredded cheddar on top if you like it cheesier.

8. Bake uncovered for 25 to 30 minutes until bubbly and the top is golden brown. If the top browns too fast, tent loosely with foil for the last 5 to 10 minutes.

9. Let it rest 5 to 10 minutes before serving so it sets up and is easier to scoop. Taste for salt and pepper and adjust if needed.

10. Tip: make ahead up to the point of baking, cover and refrigerate for up to 24 hours. Add a few fresh fried onions before baking to keep the topping crispy.

Equipment Needed

1. 9×13 inch baking dish or similar casserole dish
2. Large pot for blanching (or boiling) the beans
3. Colander and a large bowl for draining and cooling the beans
4. Large mixing bowl for the sauce and folding everything together
5. Measuring cups and spoons
6. Sharp knife and cutting board for trimming and chopping
7. Cheese grater or box grater for shredding cheddar
8. Spatula or large spoon for stirring and spreading in the dish
9. Small bowl and spoon for tossing the fried onions with melted butter
10. Oven mitts and aluminum foil for handling the hot dish and tenting if needed

Pro Tips

1. Use fresh beans when you can, they stay brighter and firmer after baking. If you must use canned, rinse and pat them dry really well so the casserole doesnt get soggy.

2. Don’t overfill the sauce with milk at first. Start with the half cup, you can always add more later if it seems too thick. Too much liquid means a runny casserole that won’t set.

3. Fold a handful of the crunchy onions into the mix, not just on top. That way you get little crispy bites throughout, not just a crunchy roof. Also toss the topping onions in butter right before baking so they brown faster.

4. Make it a day ahead if you like, but keep the topping separate. Assemble and refrigerate, then add the fried onions and a few extra cheese sprinkles just before baking so the top stays crisp and fresh.
