Healthy Green Bean Casserole Without Mushroom Soup

This Healthy Green Bean Casserole avoids canned mushroom soup by combining fresh green beans and sliced baby bella mushrooms in a creamy sauce made from milk, mayonnaise, Dijon mustard, balsamic glaze, and ranch seasoning. Crispy homemade onions made from thinly sliced onions coated in flour and panko breadcrumbs bake to golden perfection on top, along with shredded gruyere cheese for a savory finish. The casserole layers fresh textures with rich flavors without relying on processed soup bases.

Description

The recipe starts by making crispy onions in the oven, coating thin onion slices with olive oil, flour, panko breadcrumbs, and salt, then baking until lightly browned and crunchy. Meanwhile, fresh green beans are boiled to tenderness, drained, and combined with sautéed mushrooms in a creamy mixture that includes milk, light mayonnaise, Dijon mustard, balsamic glaze, ranch seasoning, salt, and black pepper.

The mixture is layered or combined and topped with shredded gruyere cheese and the baked crispy onions before finishing in the oven. This technique creates texture contrast between the creamy casserole base and crunchy topping.

This casserole serves as a lighter alternative to traditional recipes reliant on canned mushroom soup, providing fresh vegetable flavors and a homemade crispy topping. It can be adapted for gluten-free or dairy-free diets with suitable ingredient substitutions, making it versatile for various dietary preferences.

To make adjustments, gluten-free flour and panko can replace traditional flours, and vegan or dairy-free substitutes like plant-based milk, mayo, and cheese can make the dish suitable for those avoiding animal products. The topping’s crispness can be monitored closely during baking to prevent burning.

Ingredients

Servings

  • 2 onion thinly sliced, small, (300g
  • 1 Tbsp olive oil 15g
  • 1/2 cup all-purpose flour 60g
  • 1/4 cup panko breadcrumbs plus more for sprinkling, 14g
  • 1/2 tsp salt

Green Bean Casserole:

  • 2 lb. Green bean trimmed and halved, fresh
  • 2 Tbsp olive oil 30g
  • 8- oz. baby bella mushroom sliced
  • 3 Tbsp all-purpose flour 21g
  • 1.5 cups milk 2%, (360g
  • 1/4 cup mayonnaise light, (60g
  • 2 tsp Dijon mustard
  • 2 tsp balsamic glaze
  • 1 Tbsp ranch seasoning mix 7g
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 3/4 cup gruyere cheese shredded, (40g

Instructions

To Make the Crispy Onions:

  1. Preheat the oven to 450 degrees F.
  2. In a large bowl, toss the onions with olive oil then toss in the flour, panko and salt.
  3. Spray a baking sheet with cooking spray and spread the onions out evenly on the pan.
  4. Place the baking sheet on the middle rack of the oven and bake for 25-30 minutes (or until lightly brown and crispy).
  5. Toss a few times through and adjust pan as needed so onions do not burn.
  6. When done, remove from the oven and set aside. Reduce oven temperature to 350 degrees F.

Prepare The Green Bean Casserole:

  1. While the onions are cooking, prepare your green bean mixture. Bring a large pot of water to a boil and add 1 Tbsp of salt.
  2. Add the green beans and boil for 7-9 minutes or until the green beans are tender, then quickly rinse under cold water. Keep green beans in a colander in the sink for now.
  3. Heat olive oil in a large saucepan over medium heat and add the mushrooms. Cook, stirring frequently, for about 7-8 minutes or until mushrooms are tender.
  4. Sprinkle the flour over the mushrooms and stir until the flour is evenly dispersed.
  5. Then slowly add the milk and bring the mixture to a boil. Let it simmer for 10 minutes, stirring frequently, until it becomes a thick gravy.
  6. Stir in the mayo, dijon, balsamic glaze, ranch seasoning mix, salt and pepper.
  7. Spray 9x13-inch dish with cooking spray. Spread 1/3 of the sauce into the baking dish.
  8. Layer with green beans and top with the remaining sauce. Sprinkle the cheese and onions on top and bake, covered with foil, for 15 minutes.
  9. Uncover and bake for another 10-15 minutes. If the onions start to brown too much, cover the dish back with foil. Serve hot and enjoy!

Notes

  • Use gluten-free flour and panko breadcrumbs to make the casserole gluten-free.
  • Substitute dairy-free milk, vegan mayonnaise, and dairy-free cheese for a dairy-free or vegan version.
  • Replace ranch seasoning with onion powder and garlic powder if preferred or if unavailable.
