Green Bean Casserole

Green bean casserole is another Thanksgiving classic that can be modified to be a bit tastier, a lot healthier and certainly more special.  Usually the casserole is made with condensed cream of mushroom soup which provides half your daily dose of sodium in one portion. Furthermore, 50% of its calories come from fat. When you check the ingredient list you will see inflammatory oils, such as soybean and cottonseed oils, along with other unnecessary additives like MSG.I say, make your own!  It's really not as hard as it may seem, and making your own mushroom sauce creates a very special dish for your loved ones.  Plus, a made-at-home sauce makes Green Bean Casserole good enough to be an "everyday" food rather than a dish that as saved for once a year.

  • 1 pound mushrooms (see picture below)
  • 3 cloves garlic, minced
  • 1/2 onion, diced
  • 2 tablespoons organic olive oil
  • 1 pound green beans, trimmed
  • 2 tablespoons corn starch
  • 2 cups skim organic milk
  • Salt and pepper to taste


  • 1 onion, roughly chopped
  • 3 tablespoons organic olive oil
  • 2 slices gluten free or 100% whole grain bread, toasted

Or top with toasted slivered almonds.  And if it just isn't Green Bean Casserole without French's Crispy onions, then go for it with a light hand since the first ingredient is oil, not onions ;)

  1. Pre-heat the oven to 350 degrees.
  2. Start by slicing and dicing your mushrooms into pieces as small as you'd like.  Mince the garlic and dice the onion. Put the mushrooms, onion and garlic in the food processor for a fine chop.
  3. Heat the olive oil over medium heat in a large, deep sauté pan and add the mushrooms, garlic and onion.
  4. Sautee the mushroom, onion and garlic over medium heat until the mushrooms are soft and wilted, about 10 minutes.  Add a tablespoon or two of broth to soften the mushrooms further if you'd like.
  5. While the mushrooms are cooking, trim the green beans and, if you'd like, cut into smaller pieces or keep them as long green beans.
  6. Mix the cornstarch into the milk.
  7. When the mushrooms are nicely softened, add the milk with cornstarch and allow to simmer until thickened.  Add more corn starch if you want a thicker sauce.  Remember to mix the cornstarch with cold or room temperature milk, water, or oil before adding it to the hot pan.
  8. Season with salt and pepper to your liking.
  9. Add the green beans; stir to coat the beans and transfer the green beans into a casserole dish.
  10. Bake the casserole at 350 degrees for 30 minutes or until bubbly.
  11. For the topping, caramelize onions by warming the olive oil over medium low heat and adding sliced onion to cook slowly for about 20 minutes until soft and golden.
  12. While the onions are cooking, pulse 2 pieces of gluten free toast in the food processor until you get coarse crumbs.  If you are not eating gluten free, pick up a bag of 100% whole wheat Panko breadcrumbs (see picture below) or make your own crumbs with 100% whole grain bread.
  13. Remove the casserole from the oven and top with the onions, then the bread crumbs.  Place back in the oven under the broiler for just a few minutes to crisp the crumbs.

Make ahead tips~

  • The mushroom sauce can be made ahead and refrigerated for 7 days or frozen for a long time
  • The casserole filling can be made ahead and refrigerated for 7 days and then cooked on the day you want to serve it; cook the onions and make breadcrumbs, but keep them in separate containers and refrigerate for 7 days.  Bake the casserole and top with onions and breadcrumbs as directed above the day you want to serve it.
