  • 1 pound fresh green beans, trimmed and cut into bite-sized pieces

  • 8 ounces mushrooms, sliced

  • 2 cloves garlic, minced

  • 2 tablespoons olive oil

  • 1 cup unsweetened almond milk (or any dairy-free milk)

  • 2 tablespoons coconut flour (or almond flour)

  • 1/2 cup grated dairy-free cheese (optional)

  • 1/2 cup crispy fried onions (look for a low-carb or gluten-free option)

  • Salt and black pepper, to taste


1. Blanch the Green Beans:

  • Bring a large pot of water to a boil. Add the green beans and cook for 3-4 minutes until they are bright green and slightly tender. Drain and immediately transfer them to a bowl of ice water to stop the cooking process. Drain again and set aside.

2. Sauté the Mushrooms:

  • In a large skillet, heat the olive oil over medium-high heat. Add the sliced mushrooms and cook for about 5-7 minutes until they are browned and any liquid has evaporated. Add the minced garlic and sauté for another 1-2 minutes. Remove from heat.

3. Make the Low-Carb Creamy Sauce:

  • In a saucepan, whisk together the almond milk and coconut flour until smooth. Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens (about 3-5 minutes). Remove from heat and season with salt and black pepper.

4. Assemble the Casserole:

  • Preheat your oven to 350°F (175°C).

  • In a large mixing bowl, combine the blanched green beans, sautéed mushrooms, and low-carb creamy sauce. Gently mix until the green beans are well coated.

5. Bake:

  • Transfer the mixture to a greased casserole dish. If desired, sprinkle dairy-free cheese on top.

  • Bake in the preheated oven for 20-25 minutes, or until the casserole is hot and bubbly, and the cheese (if using) is melted and slightly golden.

6. Garnish and Serve:

  • Remove the casserole from the oven and sprinkle the crispy fried onions evenly over the top.

  • Serve your delicious Low-Carb Green Bean Casserole as a side dish for a tasty and healthier twist on a classic favorite.

Enjoy this low-carb version of green bean casserole without compromising on flavor!
