Ingredients
Green Beans
2poundsfresh green beansends trimmed and chopped into bite-sized pieces
While the water comes to a boil, prepare the green beans by trimming off the ends and cutting the beans into bite-sized pieces.
Once the water is boiling, add the green beans and 2 teaspoons of salt. Lower the heat and simmer for 8-14 minutes to cook and soften the beans. You don't want them fully cooked, but they should be soft. Drain the water to keep them from cooking any further.
Mushroom Sauce
Preheat your oven to 350ºF.
In a small bowl, mix together the flour, nutritional yeast, and salt.
Sauté the mushrooms and garlic in a large, deep pan until softened, about 8 minutes.
Sprinkle the flour mixture over the mushrooms and mix to coat.
Turn the heat to low and slowly stir in the broth and milk.
Continue to stir until the sauce thickens to a gravy consistency, about 5-8 minutes.
Add the green beans to the pan and mix until coated in the sauce.
Tip: If your sauce is too thick, add more milk to achieve a gravy consistency. If your sauce isn’t thickening, whisk together 1 Tablespoon of non-dairy milk with 1 Tablespoons flour. Add half of the milk mixture at a time to thicken the sauce.
Baking the casserole
Transfer the green beans and sauce mix to a 9x9-inch casserole dish.
Evenly top the green bean casserole with french-fried onions.
Bake at 350ºF for 15-20 minutes to warm the casserole and brown the crispy onions on top.
Notes
For a one-pan dish, use a cast iron pan to saute the mushrooms and bake the casserole.
To make this recipe ahead: Follow the instructions until you transfer the green beans and mushroom sauce to a casserole dish in step 1 of baking the casserole. Leave off the fried onions, cover the dish with foil, and store it in the fridge. When you’re ready to bake, leave the dish covered and bake at 350ºF for 10-15 minutes to bring it to room temperature. Then carefully remove the cover, top with the fried onions, and bake per the instructions.
