Easy Gluten Free Green Bean Casserole From Scratch

0 Prep. Preheat oven to 375°F. Grease a small casserole dish with olive oil spray.
1 Saute mushrooms. Heat butter in a large skillet over medium-high heat. Add mushrooms and sauté 3 to 4 minutes until softened. Stir in garlic powder or garlic-infused oil and shallots or shallot-infused oil.
2 Pour in chicken broth and milk. Stir and bring to a gentle simmer. Add chopped sage, tamari, salt, and pepper. Simmer 1 to 2 minutes. Add gluten free flour 1 tablespoon at a time and whisk vigorously to avoid clumping.
3 Add the fresh green beans to the casserole dish and pour the mushroom broth mixture over top, tossing to fully coat.
4 Top. Sprinkle with Parmesan cheese and gluten-free panko crumbs.
5 Bake. Bake for 30 to 35 minutes, or until the top is golden brown and bubbling around the edges.
6 Garnish. Garnish with crushed pecans or almonds before serving if desired.
