How to Store and Reheat

Leftovers are the best thing about Thanksgiving! Place them in an airtight container and they will keep well in the fridge for up to 5 days. They are easily reheated over medium-low on the stovetop to serve.

How to Freeze

Freeze crockpot green bean casserole in an airtight container for up to 3 months. Let thaw overnight in the refrigerator before reheating. I recommend adding more crispy onions after reheating the casserole, as the frozen and defrosted ones will turn mushy.

Serving Suggestions

Green bean casserole pairs so well with Thanksgiving favorites, like my favorite easy Thanksgiving turkey and gravy, candied sweet potatoes, honey glazed carrots, make ahead mashed potatoes, roasted Brussels sprouts, loaded mac and cheese, vegetarian stuffing, creamed corn, cheesy roasted broccoli, and cranberry sauce.

What are the best beans to use in green bean casserole?

I make this casserole with canned green beans as they don’t require any prep, just drain them and they are ready to use. You can use fresh green beans if you prefer, just rinse and trim them first. Frozen green beans would need to be defrosted and drained to get rid of any excess water.

Can I substitute heavy cream for milk in green bean casserole?

Sure! You can use heavy cream or half-and-half for a richer, creamier casserole.

How do you keep green bean casserole from getting mushy?

Make sure not to overcook the casserole, since the green beans have already been cooked.

Why is my green bean casserole so watery?

I’ve designed this recipe to yield a perfectly creamy casserole, but you may have a different crockpot or different kitchen conditions. If your casserole seems water, try adding a thickener like flour or cornstarch and continue cooking it for a bit longer.

Can green bean casserole be made ahead and reheated?

Yes! You can prep the dish the night before and keep covered and refrigerated til ready to cook. Add an additional 30 minutes on to the cooking time if you do this.

Becky’s tips

  • Cooked in a 6-quart Crockpot.
  • To store, place leftovers in an airtight container in the refrigerator for 3-5 days.
  • To prep ahead, follow steps 1 and 2 and cover. You can refrigerate overnight (or up to 3 days) and add an additional 30 minutes of cooking time to step 3 when ready to slow cook.
  • If you plan to keep the dish warm until ready to serve, wait to add the French fried onions until just before serving to avoid the onions becoming too soggy.
  • If substituting with frozen green beans, thaw first.
  • You can double the recipe if using a 6-quart or larger slow cooker. Cook for 2.5-3 hours.
  • For non-mushroom lovers, substitute with condensed cream of chicken soup.

Storage:Store crockpot green bean casserole in an airtight container in the refrigerator for up to 5 days or in the freezer for up to 3 months.
