FAQs
Can I use canned green beans instead of fresh?
Yes! Just be sure to drain and rinse them well. They’re softer, but still tasty.
Is green bean casserole healthy?
It can be. Green beans are a great source of fiber and vitamins. For a healthier version, use low-sodium soup, skip extra cheese, or make a lighter homemade sauce.
Can I make this dairy-free?
Yes. Use unsweetened almond or oat milk and a dairy-free mushroom soup. There are also crispy onion toppings that are dairy-free.
Can I freeze green bean casserole?
You can freeze it before baking (without the fried onions). Wrap it well and store for up to 2 months. When ready to bake, thaw in the fridge overnight, add the topping, and bake as directed.
Why is my casserole watery?
Too much liquid or undercooked green beans can cause this. Use fresh beans and drain all moisture before mixing with the sauce.
How do I keep the fried onions crispy?
Add them during the last 5–10 minutes of baking. This keeps them crisp and golden instead of soggy.
If you’re craving something warm, creamy, and full of nostalgic flavor, green bean casserole is the answer. Give it a try and make it your own—you might just start a new tradition in your kitchen.
