Why This Recipe Works

Thanksgiving is coming up quickly and that makes me happy! Any holiday that involves so much food gets me excited because it is no secret that I am mildly obsessed with recipes and food and EATING.

For any large spread the possibilities are endless, but for turkey day we like to stick with a few standard options. Turkey (of course), sweet potato casserole, corn, mashed potatoes and cranberry sauce to name a few.

This might be mostly a Midwest thing, but we also enjoy adding a Crockpot Green Bean Casserole to the spread because it is DELICIOUS and comforting. I typically make it in the oven, but starting now that will no longer be my go-to method.

The slow cooker version of this tasty side dish is ridiculously easy to make and comes out tasting like holiday perfection. This recipe opens up time for you to focus on other kitchen tasks when you have a lot going on.

Can You Make This Casserole Ahead of Time

Yes! That is one of the things I love about this recipe. Make this casserole up to 2 days ahead of time, but leave the French fried onions off until you are ready to serve it. Cook it in the crockpot as directed, transfer to a serving dish and cover and refrigerate.

When you are ready to serve, place the dish in a 250-degree oven for 10-15 minutes or until heated through. Top with onions!

Can You Freeze Green Bean Casserole

If you want to freeze this casserole for later use, you have a couple options:

Freeze uncooked – Combine the ingredients as directed and pour into an aluminum baking pan (minus the fried onions) and wrap tightly in foil. Place into resealable freezer bags and freeze for 3-4 months.

When you are ready to enjoy the casserole, let it thaw completely (preferably in the fridge overnight) and cook in a slow cooker as directed on the recipe.

FAQ About Green Beans

Are green beans healthy for you?

Yes, these beans are healthy for you. They are high in Vitamin K as well as provide calcium in every bite.

What is the healthiest way to eat green beans?

Green beans are healthy to eat in a variety of ways, from steaming to baking and sauteing. However, eating these beans raw isn’t recommended for everyone. It can result in people feeling nausea, diarrhea, bloating, and vomiting due to their lectin content. When you cook your green beans, it neutralizes the lectin and it improves their taste and digestibility.

How do you cook green beans without losing their nutrients?

Steaming and microwaving or preparing the green beans with a minimal amount of water is a good way to cook the beans but not lose their nutrients. They will still be cooked to crisp-tender and preserve their bright green color too.

Why do green beans turn out rubbery?

If you have a rubbery green bean, you have probably undercooked them. If they are mushy, then that shows they were overcooked. It doesn’t take long to cook green beans so be sure to stick close to the stove and watch them.
