Dairy and Gluten Free Casserole

1 pound green beans, canned or fresh, rinsed, trimmed
    and halved
2 tablespoons unsalted butter or dairy-free substitute
2 large Portobello mushrooms, sliced
½ teaspoon freshly ground black pepper
½ teaspoon garlic powder
¼ teaspoon ground nutmeg
2 tablespoons gluten-free All-Purpose Flour Blend
⅓ cup sour cream or dairy-free sour cream
2 cups dairy-free cream of mushroom soup


1. To make gluten free fried onions, preheat oven to 475 degrees. Lightly grease a baking sheet and set aside. Combine onion slices, ⅓ cup gluten free flour blend and salt in a large bowl, tossing until onions are evenly coated. Pour out onto prepared baking sheet, separating onion rings. Bake in preheated oven for 15 to 20 minutes until golden brown, tossing one or two times. Remove from oven and set aside while you prepare the casserole.

2. To make the dairy-free, gluten-free casserole, turn oven temperature down to 400 degrees.

3. If using fresh green beans, boil them in lightly salted water for 5 minutes. Rinse with cold water and drain. If using canned beans, rinse, drain and set aside.

4. In a large saucepan, melt the butter. Toss in sliced mushrooms and pepper and stir over medium heat for 5 minutes.

5. Add spices and gluten-free flour, stirring to coat. Cook an additional minute and add sour cream and soup. Reduce heat to medium-low and cook while mixture thickens, about 5 to 8 minutes more.

6. Remove from heat and stir in half the gluten free “fried” onions and the drained beans.

7. Pour mixture into a large casserole dish and cook in preheated oven for 10 minutes or until bubbly. Sprinkle remaining prepared onions on top and bake an additional 5 minutes. Serve warm.

How can this recipe be dairy free when the gluten free soup had milk in it?

I would like to know how this recipe is dairy-free using Cream of mushroom soup. Both & have cream & butter in their ingredients. Do you offer a substitution?
