Ingredients needed for making green bean casserole with bacon with text overlay.
  • Green Beans: I use a good brand of canned green beans. I prefer canned green beans over frozen or fresh beans. Canned green beans are more tender, while frozen beans are firmer. The choice is a personal preference. If using frozen beans, blanch them first so they are tender.
  • Bacon: Should I say more? Any bacon you like will work- thick or thin sliced.
  • Mushrooms, Onions, and Garlic: Provide flavors for this dish. These take this casserole from boring to extraordinary. Sliced white mushrooms or baby Bellas work nicely. Rough chop them so they cook down.
  • Cream of Mushroom Soup & Milk: These ingredients help make the casserole creamy. You could also use the low-sodium soup if desired.
  • Shredded Cheese: You can use pre-shredded cheese if desired. However, I prefer to buy a block of cheese and shred it myself if time allows. You may also experiment with your favorite cheeses. Monterey Jack, Colby, Pepper Jack, or even Smoked Gouda would be delish.
  • French Fried Onions: This ingredient is a signature for this side dish. The crispy fried onions on top add the finishing touch and a nice crunch. You’ll want to bake uncovered so they stay crisp.
  • Seasonings: Simple is best. The bacon, cream of mushroom soup, and fried onions replace the need for salt.

💭 Pro Tips

  • Drain Green Beans: Drain the canned beans well before adding them to the mix. This will prevent a watery casserole.
  • Make Ahead Casserole: Prepare this casserole, except for the onion topping and baking. Wrap the casserole in plastic wrap and refrigerate it until ready to bake. I prepared this casserole a day ahead, and it was great. When ready to bake, remove it from the refrigerator and let it rest on the counter while the oven preheats. Remove the plastic wrap, add fried onions, and bake according to directions. If your casserole has been in the refrigerator, add at least 10 more minutes to the cooking time.
  • Allow Rest Time: Let the simple green bean casserole rest for a few minutes before serving, allowing the filling to settle.

🧺 How to Store and Reheat Leftovers

Cover and Refrigerate: Cover leftovers tightly with aluminum foil or plastic wrap, or place in an airtight container and refrigerate. They will be fine for 3-4 days in the refrigerator.

Reheat: Place leftovers in an oven-safe dish and reheat at 350°F until warmed throughout. Add some fresh-fried onions for added crunch. The microwave works too, but may lose the crunch.

❔ FAQs

Can I make cheesy bean casserole ahead of time?

You can prepare this casserole up to 24 hours in advance. Assemble the casserole, refrigerate it, and then bake it when ready. Add the crispy fried onions just before baking. Remove your casserole from the refrigerator for 10-15 minutes before baking. 

Can I freeze green bean bake?

Freezing green bean casserole with cheese is not recommended. The texture of the green beans and the creamy sauce may change upon thawing and reheating.

What can I substitute for fried onions?

If you do not like the crispy fried onions, you can substitute them with toasted breadcrumbs, Panko bread crumbs, crushed potato chips, or buttery crackers.

Should I use canned green beans or frozen green beans in this bacon green bean recipe?

I prefer to use canned green beans for green bean casserole, but frozen green beans are an option. You will need to boil, blanch, or steam them before adding them to the casserole. Pat dry to remove the water.

Do I Have To Add Mushrooms?

You do not have to add mushrooms to this green bean casserole. You will still have a delicious side dish.
