Ingredients List

– 1½ pounds fresh green beans, trimmed and cut in half
– 2 tablespoons olive oil or butter
– 1 medium onion, finely chopped
– 2 cloves garlic, minced
– 8 oz mushrooms, sliced
– 2 tablespoons gluten free all-purpose flour
– 1½ cups gluten free vegetable or chicken broth
– 1 cup milk or dairy-free milk
– Salt and black pepper to taste
– ½ teaspoon dried thyme
– ½ teaspoon paprika
– 1 cup gluten free crispy fried onions or crushed gluten free crackers

Step-by-Step Instructions

Step 1: Bring a large pot of salted water to a boil, add the green beans, and blanch for 4–5 minutes until just tender but still bright green, then drain and set aside.

Step 2: Heat olive oil or butter in a large skillet over medium heat, add chopped onion, and sauté for 3–4 minutes until soft and translucent.

Step 3: Add minced garlic and sliced mushrooms to the skillet and cook for another 4–5 minutes until the mushrooms release their moisture and become lightly golden.

Step 4: Sprinkle the gluten free flour over the vegetables and stir continuously for 1 minute to remove the raw flour taste.

Step 5: Slowly pour in the broth while stirring to prevent lumps, then add milk, thyme, paprika, salt, and black pepper, cooking until the sauce thickens.

Step 6: Add the blanched green beans to the skillet and gently mix until they are evenly coated with the creamy sauce.

Step 7: Transfer the mixture to a greased baking dish and spread it evenly.

Step 8: Sprinkle gluten free crispy fried onions evenly over the top.

Step 9: Bake in a preheated oven at 375°F (190°C) for 25–30 minutes until bubbly and golden on top.
