Perfect for holiday gatherings or cozy family dinners, this casserole combines fresh green beans with a creamy mushroom sauce and is topped with crispy shallots for a delightful crunch. The best part? It’s completely compliant with Whole30 guidelines, making it a wholesome addition to your meal plan.

Ingredients Quantity
Fresh green beans 1.5 pounds
Coconut oil 2 tablespoons
Yellow onion 1, diced
Garlic 3 cloves, minced
Mushrooms (button or cremini) 8 ounces, sliced
Almond milk 1 cup
Coconut flour 2 tablespoons
Nutritional yeast 2 tablespoons
Sea salt 1 teaspoon
Black pepper 1/2 teaspoon
Coconut aminos 1 tablespoon
Shallots 2, thinly sliced
Ghee or clarified butter 1 tablespoon

Cooking Instructions:

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish with a little bit of coconut oil to prevent sticking.
  2. Prepare the Green Beans: Trim the ends of the green beans and cut them into 2-inch pieces. Bring a large pot of salted water to a boil and blanch the green beans for about 5 minutes until they are vibrant green and slightly tender. Drain them and immediately run them under cold water to stop the cooking process. Set aside.
  3. Sauté Aromatics and Mushrooms: In a large skillet, heat the coconut oil over medium heat. Add the diced onion and cook until translucent, about 3-4 minutes. Stir in the minced garlic and cook for another 30 seconds. Then, add the sliced mushrooms and cook until they release their moisture and are golden brown, about 5-7 minutes.
  4. Make the Creamy Sauce: Reduce the heat to low and stir in the almond milk, coconut flour, nutritional yeast, sea salt, and black pepper. Allow the mixture to simmer gently, stirring frequently, until it thickens slightly (about 5 minutes). Remove from heat and stir in the coconut aminos.
  5. Combine Ingredients: In a large bowl, combine the blanched green beans with the mushroom sauce, mixing well to ensure the beans are fully coated.
  6. Prepare the Shallots: In the same skillet, add a bit more coconut oil if needed and heat it over medium heat. Add the thinly sliced shallots and sauté until they are crispy and golden brown, about 3-5 minutes. Remove from heat and place them on paper towels to drain any excess oil.
  7. Assemble the Casserole: Pour the green bean mixture into the prepared baking dish. Spread it out evenly and then sprinkle the crispy shallots over the top.
  8. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, until it’s bubbling hot and the shallots are nicely browned.
  9. Serve: Once done, remove the casserole from the oven and let it cool for a few minutes before serving. Enjoy your delicious Whole30 Green Bean Casserole with family and friends!

  2. Prepare the Green Beans: Trim the ends of the green beans and cut them into 2-inch pieces. In a large pot, bring salted water to a rapid boil. Blanch the green beans for about 4-5 minutes until they turn bright green and tender-crisp. Drain them and transfer to a bowl of ice water to halt cooking. Once cooled, drain again and set aside.
  3. Sauté Aromatics and Mushrooms: In a large skillet, melt the ghee over medium heat. Add the diced onion and sauté for 3-4 minutes until softened. Stir in the minced garlic and cook for an additional 30 seconds until fragrant. Add the sliced mushrooms to the skillet and cook until they release their moisture and turn golden brown, about 5-7 minutes.
  4. Create the Creamy Sauce: After the mushrooms are cooked, reduce the heat to low. Pour in the coconut milk, and sprinkle in the coconut flour, nutritional yeast, sea salt, and black pepper. Stir the mixture and let it simmer gently for about 5 minutes until it thickens slightly. Remove the skillet from heat and mix in the coconut aminos.
  5. Combine the Ingredients: In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce. Mix thoroughly to ensure that all the green beans are evenly coated with the sauce.
  6. Transfer to Baking Dish: Pour the green bean mixture into the greased baking dish, spreading it out evenly. Sprinkle sliced almonds over the top for added crunch.
  7. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the casserole is heated through and the edges are bubbling. The almonds should also be lightly toasted.
  8. Serve: Once done, remove the casserole from the oven and allow it to cool slightly before serving. Enjoy this creamy, decadent dish as a side at your next meal!
