Healthy Green Bean Casserole

Thanksgiving is fast approaching and we want to make sure you can create the best feast possible for your family and friends! Whether you’re hosting a Thanksgiving dinner or are simply bringing along a side dish, our Healthy Green Bean Casserole recipe is bound to bring a smile to everyone’s faces. Thanksgiving meals can quickly become pretty unhealthy - with buttery turkey, high fat mac and cheese, sugary pumpkin pie and other treats traditionally featuring on the menu - so this dish will bring a much needed healthy touch to the day. It’s simple, straightforward and (perhaps most importantly) delicious, so why not give it a try?

This recipe for our Healthy Green Bean Casserole will take roughly 1 hour and 15 minutes to prepare and cook. It will create roughly four servings, but feel free to adapt the recipe if you require more or less.



  • 1 tbsp extra-virgin olive oil
  • 1 small onion
  • Salt
  • Black pepper
  • ¼ cup of panko breadcrumbs


  • 1 lb green beans
  • 1 tbsp extra-virgin olive oil
  • 1 small onion
  • 8 oz button mushrooms
  • 2 cloves garlic
  • ¼ cup of butter
  • ¼ cup of all purpose flour
  • 2 cups of 2% milk
  • 1 cup of low sodium vegetable stock
  • Salt
  • Black pepper


1. Preheat your oven to 375 degrees.

2. Start by preparing your topping. Heat your tbsp of extra virgin olive in a large skillet over a medium heat. Finely slice your onions and place them in the skillet. Cook them for roughly four to six minutes until they are golden and soft. Remove from the heat and place in a large, glass mixing bowl. Add your panko crumbs and toss the mixture. Then add salt and pepper to taste.

3. Next, it’s time to prep your green beans. Fill a large bowl with ice water, allowing enough room to add your green beans. Add your green beans to a pot of boiling and salted water. Cook them for about three minutes until they are tender. Drain the green beans and add them to the ice bath to cool. Then drain them again and transfer them to a large bowl.

4. Now, prepare your casserole filling. Put your second tbsp of extra virgin olive oil into your large skillet over a medium heat. Slice your second small onion and add it to the pan, allowing it to cook for around five minutes until it is golden and soft. Slice your button mushrooms and add them to the pan. Stir the onions and mushrooms until the mushrooms are cooked through. Add your garlic and salt and pepper to taste. Then, add the mixture to your bowl of green beans.

5. Add your ¼ cup of butter to the skillet and maintain a medium heat. Add your flour and whisk for roughly two minutes. Then add your milk and vegetable stock and whisk. Bring the mixture to a simmer and add salt and pepper to taste. Cook for around four minutes until the mixture thickens.

6. Remove your mixture from the heat and add in your green bean mixture. Toss all of the ingredients together until the green beans are completely coated in the sauce. Transfer to a casserole dish.

7. Place the casserole dish into your preheated oven and bake for 20 minutes. Remove the dish from the oven and evenly distribute your topping over the top. Place the casserole dish back in the oven and cook for a further 10 minutes until it is golden and crispy.

8. Remove from the oven and allow to cool to a suitable temperature for eating. If you are saving it to take to a Thanksgiving meal, allow the dish to cool, cover with tin foil and refrigerate. When you arrive at your meal, it can be eaten cold or reheated.

As you can see, this dish is packed with greens and will add a healthy and delicious side to your Thanksgiving meal. So, why not give it a try?
