How to Make Green Bean Casserole

This green bean casserole comes together in 3 parts. First, make the fried onions, then the casserole, and finish by cooking the whole thing in your smoker.

1. Make the crunchy onion strings. Start off by making some crunchy onion strings from scratch. These guys are truly magical and make this casserole better than any other you’ll have. 

2. Make the green bean casserole. Blanch the green beans, saute the mushrooms and combine all ingredients for the casserole in a 12-inch cast-iron skillet. Top with those crunchy onion strings you just made and this casserole is ready for its final bake!

3. Cook the casserole in the smoker. With your smoker preheated to 400 degrees F, smoke the green bean casserole for 30 minutes. It’s best to serve this dish right away to ensure the beans are nice and crisp. 

One final note: If you have a full day of baking ahead of you, this casserole can be prepped in advance. You can make the green bean mixture and the fried onions a day or two in advance, refrigerate, and then smoke just before serving.

If you don’t have access to a smoker, this casserole tastes just as good baked in the oven. This casserole can be cooked in an oven just like you’d cook it in the smoker. Simply preheat your oven to the same temperature as specified in the recipe card (400 degrees F), follow the instructions as written to make your fried onions, and cook the entire casserole in the oven at 400 degrees F for approximately 15 minutes.
