Ingredients

Fried Onions

  • 2 onions medium-sized
  • 1 pint buttermilk
  • 2 cups all purpose flour
  • ½ tbsp Kosher salt
  • 1 tbsp black pepper course grind
  • 1 tsp garlic powder
  • ½ tsp cayenne pepper optional
  • Vegetable oil for deep frying

Smoked Green Bean Casserole

  • 4 cans cut green beans 14.5oz cans
  • 2 cans cream of mushroom soup 10.5oz cans
  • 1 cup whole milk
  • tbsp soy sauce
  • 1 tsp Kosher salt
  • 1 tsp black pepper course grind
  • ½ tsp garlic powder
  • ½ tsp onion powder

Instructions

Fried Onions

  • Thinly slice your onions.
  • Transfer the sliced onions to a medium-sized bowl and pour the buttermilk over the top. Make sure the onions are fully-submerged and let them soak for 10 minutes (but not longer than 30 minutes).
  • In a medium sized bowl, combine the all-purpose flour, salt, pepper, garlic powder, and cayenne pepper.
  • Heat the vegetable oil in a pot over medium-high heat until it reaches 350°F.
  • Once the onions have soaked for 10 minutes, pull them out of the buttermilk and dredge them in the seasoned flour, then drop them in batches into the hot oil. Let them cook for about 5 minutes per batch until they reach a golden-brown color.
  • Remove the fried onions from the oil and transfer them to a paper towel lined plate to cool while you prepare your casserole.

Smoked Green Bean Casserole

  • Pre-heat your smoker to 350°F.
  • In a casserole dish or aluminum tray, combine the cut green beans, cream of mushroom soup, milk, soy sauce, and seasonings. Stir until well-combined and the green beans are fully coated.
  • Place your casserole directly on the grates of your smoker and let it smoke for 25 minutes.
  • Add the crispy fried onions all over the top of your casserole and let it continue to smoke for 10 more minutes until the onions are crispy and the casserole is slightly bubbly. Serve immediately.

Notes

Can I use fresh green beans? Yes! The trick if you want to use fresh green beans is to boil them for about 6 to 7 minutes before adding them to your casserole so that they are fully cooked in the final product.
Can I use homemade cream of mushroom soup? Yes! The key to using homemade cream of mushroom soup is to ensure that you mince your mushrooms into small pieces so that the size of the mushrooms doesn’t overpower the green beans.
Can I use the store-bought fried onions in this recipe? Yes! While I greatly prefer my homemade fried onions because they’re SUPER easy to whip up and more flavorful, the store-bought fried onions will work just fine. If you do choose to use the store-bought variety, I recommend adding about ½ cup of fried onions to the green bean mixture and then adding even more to the top.
Can I make this recipe in the oven instead? Of course, you can go the traditional route and make this recipe in the oven – but I prefer the smoker because it adds an extra layer of smoky flavor that really takes the dish up a notch. Plus, it saves room in the oven/kitchen for all of the other amazing Thanksgiving food that you are whipping up!
Can I prep this ahead of time? Yes! You can prep the green bean casserole up to 3 days in advance and store it in the fridge until you are ready to cook it. I recommend making the fried onions on the day of so they retain their crispy exterior, though.
What wood should I use to smoke it with? We used oak for this recipe. but any wood that provides a subtle smoky flavor that won’t overpower the dish would be suitable.
