How To Prepare This Gluten-Free Green Bean Casserole In Advance

Prepare the gluten-free green bean casserole ahead of time by trimming and blanching the green beans and storing them along with the prepared cream of mushroom soup separately in the refrigerator.

Just before baking, add the gluten-free fried onions or preferred topping, adjusting the baking time as needed since the casserole will be cold.

This allows for a convenient make-ahead option, streamlining the cooking process and ensuring a timely and hassle-free preparation on the day of the meal.

CAN I PREP THE GREEN BEANS THE NIGHT BEFORE?

Secondly, ensure you're not adding excess liquid initially. Adjust the baking time and temperature if needed, giving it a little more time in the oven to let the moisture evaporate.

Lastly, let the casserole rest for a few minutes after baking, allowing the ingredients to settle and the excess moisture to be absorbed, resulting in a firmer texture.

What Shortcuts Can I Use For This Recipe?

To simplify the process of making a gluten-free green bean casserole, consider using store-bought gluten-free cream of mushroom soup and pre-cut green beans.

Opt for pre-made gluten-free fried onions instead of making them from scratch. Plan ahead by prepping some components, such as blanching the green beans, the day before.
