🥄 Equipment
You'll need the following items to make this simple green bean casserole successfully.
🥫 Storage
Even though we all like to sit around the table after Thanksgiving dinner take a minute to handle the leftovers for safety's sake!
Leftovers should be covered with plastic wrap and refrigerated for up to 2 days. After that it starts getting watery.
This classic casserole, made with the canned cream of mushroom soup, can be frozen for up to 3 months as long as you leave the onion topping off. If you make it with homemade white sauce it won't freeze well at all.
💭 Tips
Expert Tip: If you use frozen green beans be sure to thaw them completely, drain for a few minutes in a colander, and pat dry. Too much liquid will make the casserole too watery.
- Cut green beans are best for this because they fit on a fork or spoon better but you can use French style or whole, too.
- Substitute any cream soup for the cream of mushroom.
- You can assemble this ahead of time, cover with plastic wrap, and refrigerate for 2 days. Just wait to add the crispy onions until just before baking.
- See the FAQs section for suggested substitutions for the onions.
- The soy sauce enhances the mushroom flavor but you can leave it out if you wish - especially if you are watching your salt intake.
👩🍳 FAQs
It's about 2 (15-oz) cans, drained.
Crushed Ritz crackers, crushed potato chips, crushed croutons, or crispy bread crumbs are all good ways to top a casserole!
Use fresh, cooked green beans plus sauteed mushrooms and onions, mixed with a homemade white sauce and topped with crispy bread crumbs or homemade French fried onions (I've got the recipe right here).
Sure! Leave out the crispy fried onions and you can make green bean casserole up to 3 days ahead of time. Add the onions just before baking.
📖 Variations
- Use Worcestershire sauce in place of soy sauce.
- Substitute another condensed cream soup for the cream of mushroom soup. Cream of chicken soup is good.
- Got bacon lovers?? Top with crumbled crispy bacon
- Sprinkle with Cheddar cheese for the cheese lovers before adding the onion topping.
- Add a few sauteed, sliced mushrooms if you like them.
- Add cooked pearl onions in with the green beans.
- Busy weeknight? Stir in cooked chicken breast or ground beef for a delicious main dish casserole.
