Ingredients

1 lb green beans rinsed, trimmed and halved
8 oz mushrooms
4 cloves garlic minced
1 cup low-sodium vegetable broth
1 cup unsweetened almond milk
2 tablespoons cornstarch
2 cups crispy french fried onions divided
½ teaspoon salt
¼ teaspoon black pepper

Instructions

Wash green beans and trim ends off. Then, slice in half to shorten the beans.
1 lb green beans
Boil beans for 5 minutes, drain and set aside.
Pre-heat oven to 400°F (205°C).
In a large skillet over medium heat, add mushrooms and garlic. Cook until excess moisture from mushrooms is released. About 5 minutes.
8 oz mushrooms, 4 cloves garlic
Add the vegetable broth and non-dairy milk.
In a small bowl, create slurry by mixing the corn starch with 2 parts water until dissolved, then stir in to mushroom mixture. Season with salt and black pepper. Bring to a boil then reduce to a rolling simmer for 3-5 minutes until it starts to thicken.
1 cup low-sodium vegetable broth, 1 cup unsweetened almond milk, 2 tablespoons cornstarch, 1/2 teaspoon salt, 1/4 teaspoon black pepper
Remove from heat and add the cooked green beans and half the crispy onions. Toss to coat well.
2 cups crispy french fried onions
Transfer to a casserole dish. Evenly distribute mixture, then top with remaining crispy onions. Bake for 15 minutes until top onion starts to become golden and brown.

Notes

No cornstarch? If you don't have that on hand you can also use all-purpose flour and double the amount since flour is not as strong of a thickener as cornstarch.

No need to make a slurry with flour, just sprinkle it over the cooked mushrooms and stir for a minute to heat through and a create a roux, then add the broth and milk.

Make Ahead

You can cook the green beans ahead of time and make the sauce and store them together in the refrigerator for a couple days. When you're ready to serve, add the crispy fried onions and bake it to heat it back up.

How to store

Store cooked green bean casserole in an airtight container in the refrigerator for up to a week.

Reheat in microwave for convenience or to maintain crispiness of the onions on top you can reheat in the oven.
