Green Bean Casserole

This Green Bean Casserole is the perfect side dish to bring to any gathering. I took this casserole and made it healthier with all homemade ingredients. There is no canned soup or crispy canned onions in this casserole.

Instead of using canned soup I opted for my own homemade mushroom cream sauce. It is the best part of this recipe! I saute mushrooms in butter and add flour to thicken the sauce along with milk, chicken stock and parmesan cheese.

To give this easy green bean casserole lots of crunch I top it with toasted panko breadcrumbs and diced onions for my homemade crispy onion topping. It is so much better than the canned version!

Fresh green beans are best in this recipe however I have tried it with frozen green beans in a pinch. If you are using frozen make sure to drain any excess moisture out of the beans before adding to the mushroom sauce.

How to make Green Bean Casserole

  • Saute green beans: Add 1 tablespoon olive oil to a large skillet. Add in green beans and sauté for 3-4 minutes. Set aside. (They will still be crunchy that is fine they will continue to cook in the oven.)
  • Make the crispy onion topping: Add 1/2 tablespoon of butter to the same skillet as the green beans. Add onion and sauté for 2-3 minutes or until slightly tender (they continue to cook in the oven). Set aside in a medium bowl. Add the remaining 1/2 tablespoon of butter to the same skillet. Add panko and cook until golden brown and toasted, 1-2 minutes. Remove from the pan and toss with the onions along with the parmesan cheese, salt and pepper. Set aside.
  • Make the mushroom cream sauce: Heat butter in a medium sauce pan. Add mushrooms and saute for 3-4 minutes or until tender and golden brown. Add garlic and sauté for 1 additional minute. Whisk in flour and stir constantly for 1 minute. Slowly pour in chicken stock and milk. Allow the sauce to simmer stirring constantly until thickened. Season with salt and pepper to taste and set aside.
  • Assemble: Toss the green beans in the mushroom sauce and spread in a 9 x 13 baking dish. Top with the crispy onion panko topping.
  • Bake: Bake for 20-25 minutes or until golden brown and warmed through. Serve immediately and enjoy!
  • Store: Leftovers can be stored in an airtight container up to 3 days!
  • Reheat: To reheat this casserole simply bake at 350 degrees for 20 minutes or until heated through.
