Ingredients you will need

  • Green beans- Use fresh, frozen, or canned green beans for this casserole. Fresh green beans offer a satisfying crunch, while frozen green beans are convenient and retain their nutrients, making either option perfect for creating a classic, hearty casserole. Canned are good for convenience.
  • Onion & garlic- Add depth and rich flavor to the dish. Sautéing them enhances their natural sweetness and creates a savory base that complements the green beans, making the casserole more aromatic and delicious.
  • Mushrooms- Create a rich, umami flavor and meaty texture that enhances the dish. Their earthy taste complements the freshness of the green beans and the creaminess of the sauce, creating a well-rounded and satisfying casserole.
  • Nutritional yeast- Adds a cheesy, savory flavor without any dairy. It contributes a rich, umami taste that enhances the overall depth of the dish while also being an excellent addition for achieving a creamy, flavorful sauce that satisfies cravings for comfort food while keeping the dish plant-based and nutritious.
  • Seasonings– Soy sauce, onion powder, garlic powder, nutmeg, thyme, and smoked paprika help create the delicious profile of this casserole.
  • Bread crumbs- Dairy-free breadcrumbs are used in green bean casserole to create a crispy, flavorful topping that adds texture and contrast to the creamy filling.

Tips & Suggestions

  • Green Beans: Either fresh, canned, or frozen green beans can be used in this recipe. I chose to use canned but any of these will work just fine.
  • Thickness: When adding the flour, milk, and spice mixture to the hot pan, if it seems too thick, simply add more plant milk to get to the desired consistency.
  • Making Cashew Parmesan: The homemade vegan parmesan is optional, but I highly recommend it. It’s very simple to make and keeps for weeks at room temperature and months in the refrigerator. It can be added to veggie pizza, pasta, and many other recipes.
  • Make-Ahead-Dish: This vegan casserole is a great make-ahead casserole that reheats well. Cook ahead of time or assemble and keep in the refrigerator until ready to bake.

How to make vegan green bean casserole

The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.

STEP #1: Preheat the oven to 350°F and line a 2-quart casserole dish (approximate size) with parchment paper to prevent sticking.

If using fresh green beans, wash them, trim ends, and cut them into bite-size pieces. Set to the side.

STEP #2: Heat a non-stick skillet and add the onion slices. Allow them to begin browning and then add a little veggie broth. Continue cooking and stirring for approximately 5 minutes. See my demo video of this recipe below to see how this is done. I love my Ozer non-stick pan for sauteing vegetables without oil.

STEP #3: If using fresh or frozen green beans, add approximately 1/3 cup more of veggie broth and the beans to the pan and allow to cook for 5 minutes. If you are using canned green beans, you can skip this step because the cooked beans will be added later.

STEP #4: Next, add minced garlic and diced mushrooms, along with the white wine to the pan and cook another 5 minutes, stirring often.

STEP #5: In a small bowl, combine flour, plant milk, soy sauce, nutritional yeast, and all the spices EXCEPT for the smoked paprika. Whisk together well.

STEP #6: Add this milk-spice mixture to the pan of veggies and stir until thickened, approximately 2-3 minutes.  If it becomes too thick, add a little more milk.

STEP #7: Now is the time to add canned green beans if you are using them. Coat them well with the thickened mixture.

STEP #8: Pour into the casserole dish lined with parchment paper and spread out the mixture evenly in the pan.

Top with dairy-free panko or breadcrumbs. Next, sprinkle sliced almonds and smoked paprika over the top. Another great addition is homemade vegan parmesan, though it is optional.
