What Makes This Green Bean Casserole Dairy-Free and Gluten-Free?

Unlike traditional casseroles that rely on cream of mushroom soup and milk-based sauces, this version uses a homemade dairy-free mushroom gravy that gets its creaminess from plant-based milk and thickening agents like flour or starch. It’s naturally vegan and gluten-free adaptable by using gluten-free flour and crispy onions.

And yes—those crispy onions can be made gluten-free too with your favorite store-bought brand or a quick homemade batch.

This recipe is perfect for those avoiding dairy, gluten, or just looking for healthier holiday sides that don’t skimp on comfort.

How to Make Dairy Free Green Bean Casserole in a Skillet

Step 1: Prep the green beans.
Bring a large pot of salted water to a boil. Add the green beans and blanch them for 5 minutes until slightly tender. Drain and set aside.

Step 2: Sauté the vegetables.
In a large skillet, heat olive oil over medium heat. Add chopped onions and cook until translucent, about 5 minutes. Stir in the garlic and sliced mushrooms, cooking until mushrooms are soft and browned.

Step 3: Make the dairy-free cream sauce.
Sprinkle flour over the mushroom mixture and stir well to coat. Slowly pour in the vegetable broth while stirring to prevent lumps. Add almond milk and continue stirring until the sauce thickens. Season with salt, pepper, and any additional herbs or spices you like.

Step 4: Combine the casserole.
Stir the blanched green beans into the skillet and toss to coat evenly in the sauce.

Step 5: Add crispy onions and bake.
Sprinkle crispy onions over the top. Bake in a 375°F oven for 15–20 minutes, or until bubbly and golden.

Step 6: Serve hot and enjoy.
This skillet casserole is best served immediately but still tastes amazing reheated.
