Recipe Info
Let’s get to the guts of it. Green Bean Casserole with Crispy Fried Onions has been around longer than my grandma’s favorite apron, but modern tweaks make all the difference. You can use fresh beans (fancy), but if you’re like me, sometimes you grab the frozen or canned kind (no shame at all). The crispy fried onions part is non-negotiable in my book. They add this magical crunch, salty pop, and are borderline addictive. Cream of mushroom soup? Classic. But you can also substitute with cream of chicken if you’ve got picky mushroom-haters at home. A sprinkle of sharp cheddar melted on top isn’t traditional, but it’s my cheesy upgrade for chilly nights.
You know what else? Casseroles are forgiving. Bad day? Burnt one? Just pile on more onions, trust me. The beauty is in the balance rich and cozy but salty and snappy, too. Sometimes, I’ll toss in leftover rotisserie chicken if it’s testing day at the fridge. Makes it a full-on meal. I also love this with a spoonful of hot sauce mixed in, but that’s just if you like to live a little. 
How to make Green Bean Casserole
So, here’s how I throw it together. You’ll need:
- 1 can cream of mushroom soup (like, 10.5 oz)
- 3 to 4 cups green beans (if you want more, I won’t stop you)
- ⅔ cup milk (or half-and-half if you’re feeling wild)
- 1 ½ cups crispy fried onions (some for topping, some for inside)
- Salt and pepper to taste
- Optional: shredded cheese (because cheese is life)
I just stir together the soup, milk, salt, and pepper in a big bowl. Dump in the green beans and about half those fried onions. Mix, don’t be shy. Pour into a baking dish and bake at 350°F for 25 minutes (honestly, sometimes I forget and leave it in for 30… comes out fine). After, toss the rest of the onions (and cheese, if using) on top and bake for another 5 minutes, till bubbly and golden and the onions get nice and crisp.
Scoop it up and let the compliments roll in. The hardest part is not snacking on the fried onions before they hit the casserole. It happens.
| Ingredient | Amount | Notes |
|---|---|---|
| Cream of Mushroom Soup | 1 can (10.5 oz) | Classic choice; can substitute with Cream of Chicken |
| Green Beans (fresh or canned) | 3-4 cups | Fresh beans are fancy; canned are easy |
| Milk | ⅔ cup | Or half-and-half for extra creaminess |
| Crispy Fried Onions | 1 ½ cups | Some for topping, essential for crunch |
| Salt and Pepper | To taste | Basic seasoning; adjust as needed |
| Shredded Cheese (optional) | To taste | Sharp cheddar is great for flavor |
Insider tips: things to know
Here’s the deal fresh green beans are great, but they take a bit more work. You gotta trim the ends and maybe blanch them a little so they’re not tough. Canned beans are easy, but rinse them or the casserole can get extra salty. As for the soup, a little dash of garlic powder in the base can wake up the whole thing (secret ingredient alert).
The crispy fried onions are your wild card. Some brands are, honestly, tastier than others. I’m partial to the name-brand stuff, even if it’s a couple bucks more. Cheap ones get soggy. Oh, and if you want this to feel like a five-star restaurant, a sprinkle of smoked paprika goes a long way.
Don’t skip the resting time. I know, everyone’s already reaching for seconds, but five minutes lets things set up and the flavors chill out. That’s when it goes from good to “holy moly, dream casserole.”

Skip the boring, seriously. Leftovers like these just want a little sparkle to shine again!
