IS GREEN BEAN CASSEROLE GLUTEN-FREE?

I often get asked is green bean casserole gluten-free. Green bean casserole traditionally uses cream of mushroom soup.

While most cream of mushroom soups contain wheat, you can purchase gluten-free cream of mushroom soup, or you can make your own homemade cream of mushroom soup without wheat.

CAN I MAKE THIS GLUTEN-FREE GREEN BEAN CASSEROLE WITHOUT CREAM OF MUSHROOM SOUP?

Yes, you can. Gluten-Free Cream of Chicken Soup is also a homemade swap that is delicious here. 

HOW DO YOU KEEP GREEN BEAN CASSEROLE FROM GETTING MUSHY?

Make sure the gluten-free mushroom soup that's added is at the desired consistency. If it is too runny the casserole will come out mushy. 

HOW DO YOU MAKE A DAIRY-FREE GREEN BEAN CASSEROLE?

IS IT OK TO MAKE GREEN BEAN CASSEROLE AHEAD OF TIME?

You can, however I would suggest you cook it without the topping and add the topping when you are going to eat it. Put it under the grill until you have a nice crispy top layer.

ARE FRENCH FRIED ONIONS GLUTEN FREE?

Traditionally not, you can however make or buy gluten-free onions.

CAN I PREP THE GREEN BEANS THE NIGHT BEFORE?

Yes, you can. Just trim, wash, and blanch them if using fresh green beans and then store the green beans in the fridge for when you are ready to make the dish. 

HOW DO YOU STORE A GLUTEN-FREE GREEN BEAN CASSEROLE?

You can store it in the fridge for 2-3 days either wrapped in foil in the casserole dish or in an airtight container. The top may not be as crispy due to the moisture. 

WHAT IS THE DIFFERENCE BETWEEN FRESH GREEN BEANS VS. CANNED VS. FROZEN FOR GLUTEN-FREE GREEN BEAN CASSEROLE

Fresh green beans are the best in terms of texture. Frozen and canned beans are slightly limper but can work on those busy weeknights.

TIPS FOR MAKING GLUTEN-FREE GREEN BEAN CASSEROLE

Use a gluten-free cream of mushroom soup or make your own cream of mushroom soup.

You can use fresh or canned green beans. If using canned green beans, use 4 cups (about two cans).

You can omit the cheese from this recipe for a more traditional gf green bean casserole.
