Tips + Variations

A few things to keep in mind when making Green Bean Casserole with fresh green beans.

Boiling the beans. The green beans need to be partially cooked before mixing them in with the other ingredients. Be sure not to boil them too long, otherwise they’ll get mushy when baked.

To add some flavor to the beans, add 1 tablespoon of salt for every 8 cups water you boil.

Watery casserole. This casserole should have a nice creamy texture. A few things to keep in mind to create the perfect holiday side dish, include: 

  • If you use frozen green beans, skip boiling them in water. Be sure to thaw, or steam, and allow any excess water to drain off. 
  • Undercooking the green beans in the water can mean that any excess moisture in the beans may leak out while baking. Be sure that the green beans are tender, but not soggy. Drain and pat dry. 
  • To be extra cautious, toss the green beans in a light coating of all purpose flour after boiling them.
  • The casserole will thicken as it cools. If the casserole is notably soupy at the end of the 25 minutes, add in a cornstarch slurry before you top it with the remaining french onions.
    • Slurry: In a separate bowl, combine 2 teaspoons cold water and 2 teaspoons cornstarch. Once smooth, mix it into the casserole. Top with french onions and bake for another 5 minutes. 

Amp up the flavor. I love how this recipe turned out exactly as it is, but every cook has a different taste, and likes to change things up from time to time. Try:

  • sprinkling on cheddar cheese
  • adding cooked crumbled bacon
  • adding a bit of butter to the green beans
  • season with garlic salt

Holiday Prep + Storing

How much to make per person. When serving this for a crowd, such as a holiday dinner, one dish will serve 10-12 people. Double the recipe for 20-25 people. Triple the recipe for 30-35 people. 

Make ahead of time. Prep this casserole in a baking dish the day before, but don’t add the french fried onions on top. Cover the casserole, and keep in the fridge. When you’re ready, add the onions and bake.

STORE leftover casserole in an airtight container, in the fridge, for up to 3 days.

Reheat in the microwave, or the oven. To crisp up the french fried onions, place the leftovers under the broiler for a couple of minutes. 

We hope you enjoy this delicious Fresh Green Bean Casserole!
