30 minutes of bake time and real food ingredients is all you need to make this amazingly delicious Green Bean Casserole! So comforting and perfect for the holidays.
Before starting, prep the vegetables. Trim the green beans and cut into 1 inch pieces. Dice up the mushrooms, shallots, and garlic. Add 8 cups of water to a large pot and bring to a boil. Once boiling, add the green beans. Boil for 8-10 minutes until softened. Strain and set aside.
Preheat the oven to 350 degrees F. Heat a medium sized saucepan to medium heat. Once hot, add in the oil or butter. Saute the shallots, mushrooms, and garlic for 5-7 minutes.
Sprinkle the vegetable mixture with arrowroot starch and stir to coat the vegetables. Now add in the wine and milk, increase the heat until the mixture begins to bubble. Reduce the heat to medium low and add in the cheese. Mix until cheese is melted.
Place the green beans inside a 9x13 inch greased casserole dish. Pour the cheesy mushroom mixture on top. Top the casserole with breadcrumbs or topping of choice. Transfer to the oven.
Bake for 30 minutes, or until casserole is bubbly and lightly browned. Season with salt and pepper, and optional fresh thyme to serve!
*Use a dry white wine like a sauvignon blanc or chardonnay. You can also use vegetable or chicken broth in it's place!
**This can be whole milk or full fat coconut milk.
***Breadcrumbs can be a GF variation like nutcrumbs, or GF panko. Feel free to replace with your favorite crunch topping (check out the options in the blog post!)
