Directions

  1. Preheat the Oven:

    • Preheat your oven to 350°F (175°C).

  2. Prepare the Green Beans:

    • If you’re using fresh green beans, blanch them in boiling water for about 3-4 minutes until they are just tender. Drain and set aside. If you’re using canned green beans, simply drain and rinse them.

  3. Make the Casserole Sauce:

    • In a large mixing bowl, combine the cream of mushroom soup, milk, garlic powder, salt, and pepper. Stir until smooth. If you’d like, add in the shredded cheddar cheese for an extra creamy and cheesy layer.

  4. Assemble the Casserole:

    • Add the prepared green beans to the bowl with the soup mixture. Stir to coat the beans evenly in the sauce.

    • Transfer the mixture into a greased 9×13-inch casserole dish and spread it out evenly.

  5. Add Fried Onions:

    • Sprinkle half of the fried onions on top of the casserole.

  6. Bake:

    • Bake the casserole in the preheated oven for 25 minutes, or until it’s bubbly and the sauce is thickened.

  7. Top with More Fried Onions:

    • Remove the casserole from the oven and sprinkle the remaining fried onions on top. Return to the oven and bake for an additional 5-10 minutes, or until the onions are golden brown and crispy.

  8. Serve:

    • Once done, remove from the oven and let it sit for a few minutes before serving.
