Ingredients

Scale
  • 2 lbs fresh green beans, trimmed and cut into 2-inch pieces
  • 1 tbsp olive oil
  • 1 medium onion, finely diced
  • 2 cloves garlic, minced
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 cup whole milk
  • 1/2 cup heavy cream
  • 1 tsp Dijon mustard
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp black pepper
  • 1/2 tsp salt
  • 1 cup crispy fried onions
  • 1/4 cup panko breadcrumbs
  • 2 tbsp melted butter

Instructions

  1. Prep the green beans by washing, trimming, and cutting them into bite-sized pieces. Set aside.
  2. Heat olive oil in a large skillet or Dutch oven over medium heat. Sauté diced onion until translucent (3-4 minutes), then add minced garlic and cook for 30 seconds until fragrant.
  3. Add green beans to the skillet with 1/4 cup water. Cover and steam for 5-7 minutes until tender-crisp. Drain excess water.
  4. In a separate saucepan, whisk together cream of mushroom soup, milk, heavy cream, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth. Heat gently until warm.
  5. Pour the warm sauce over the cooked green beans and onions in the skillet. Stir gently to coat evenly.
  6. Transfer the mixture to a 9×13 inch casserole dish and spread evenly.
  7. In a small bowl, mix crispy fried onions, panko breadcrumbs, and melted butter. Sprinkle evenly over the casserole and press down gently.
  8. Preheat oven to 375°F (190°C). Bake for 20-25 minutes until sauce is bubbly and topping is golden brown.
  9. Let rest for 5 minutes before serving to allow sauce to thicken.

Notes

Do not overcook the beans; steam them only until tender-crisp as they will continue to cook in the oven. For make-ahead, assemble up to 24 hours in advance and refrigerate, adding 10-15 minutes to baking time. To freeze, assemble before baking and freeze for up to 3 months.
