  • Bring a large pot of salted water to a boil. Add the green beans, and cook until bright green and crisp-tender, about 10 minutes. Drain and shake off any excess moisture in colander and set aside.

  • Melt the butter in the large pot over medium heat. Add the diced onions, ¼ teaspoon RFS Smooth & Mellow, ¼ teaspoon salt and cook, stirring, until soft, about 8 minutes.

  • Add the diced mushrooms, ¼ teaspoon RFS Smooth & Mellow, ¼ teaspoon salt and continue to cook, stirring, until they are soft and most of their liquid has evaporated, about 10 minutes.

  • Sprinkle the flour over the vegetables, and stir until all the flour is absorbed (about 1 minute).

  • Add the chicken broth, half-and-half, ½ teaspoon RFS Smooth & Mellow and ½ teaspoon salt. Stir and bring broth to a light boil over medium high heat. Reduce to medium heat and simmer until the sauce thickens to coat the back of a spoon, about 5 minutes.

  • Preheat oven to 350 degrees

  • Remove the mushroom soup from the heat, add the green beans and stir to coat in the sauce. Transfer the mixture to a 3-quart baking dish coated with non-stick cooking spray.

  • Top the green bean mixture with fried onions and bake until the casserole is hot and bubbly and the onions have crisped slightly, 20 to 25 minutes.

Serves 4 to 6
