Tips & Variations

  • For a richer flavor, try adding a splash of soy sauce or Worcestershire sauce to the mixture before cooking.
  • You can substitute cream of mushroom soup with a homemade white sauce for a fresher taste.
  • Add cooked bacon bits or sautéed mushrooms for extra texture and flavor.
  • If you prefer a thicker casserole, reduce the milk slightly or add a tablespoon of cornstarch mixed in with the soup.

Storage

Store leftover green bean casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. The crispy onions may soften upon reheating, so add fresh fried onions on top if you like.

FAQs

Can I make this casserole ahead of time?

Yes, you can prepare the casserole up to step 3, cover it, and refrigerate overnight. Add the toppings and cook in the crockpot as directed when ready to serve.

Can I use fresh green beans instead of canned?

Absolutely. Use about 1.5 pounds of fresh green beans, trimmed and blanched, to replace the canned ones. This will add a fresher texture and flavor to the dish.
