How Long To Reheat Green Bean Casserole

So how long exactly should you reheat green bean casserole in the oven? The timing depends on a couple of factors.

Amount You’re Reheating

The first factor is how much green bean casserole you’re reheating.

• For a smaller portion, about 2-3 servings, you’ll only need 15 minutes covered and 5 minutes uncovered.

• For a larger portion, closer to 4-6 servings, do 20 minutes covered and 5 minutes uncovered.

Thickness Of The Casserole

The thickness of your casserole also plays a role. A thicker, more dense casserole will take a bit longer to reheat through to the middle than a thinner one.

• For a thinner green bean casserole, start checking after 15 minutes covered.

• For a very thick casserole, you may need the full 20 minutes covered. Check for hotness before uncovering.

Test With A Thermometer

The most foolproof way to check your green bean casserole is with an instant read thermometer.

• Green bean casserole is safely reheated once it reaches 165°F in the center.

• If it’s not there yet after 20 minutes covered, do 5 more minutes covered and keep checking.

To get the most out of reheating your green bean casserole in the oven, follow these tips:

• Let refrigerated casserole sit at room temp for 15 minutes before baking for more even reheating.

• Stir halfway through baking to distribute heat.

• Add extra fried onions before the last 5 minute uncovered baking to refresh the topping.

• If the top browns too quickly, tent foil over the casserole.
