How to Make Dairy Free Green Bean Casserole
-
Preheat oven: Set your oven to 400°F while you prepare the other ingredients. This temperature is crucial for achieving that delightful golden top.
-
Blanch green beans: In a large pot of boiling water, add the whole or halved green beans. Cook for 5 minutes, then quickly transfer them to an ice bath to stop the cooking process. Drain and set aside for added crunch.
-
Sauté mushrooms: In a large skillet over medium heat, melt the vegan butter. Add the sliced mushrooms, season with salt and pepper, and let them cook for about 5 minutes. Incorporate minced garlic and sauté until fragrant, about 1 minute.
-
Make the creamy sauce: Sprinkle flour over the mushrooms, stirring well to coat. Gradually stream in vegetable broth while stirring; bring to a simmer, which will thicken the mixture into a creamy consistency that’s simply irresistible.
-
Add dairy-free milk: Reduce the heat to low and blend in the dairy-free milk. Cook for an additional 5 minutes or until your sauce reaches the perfect creamy texture. Taste and adjust seasonings as needed. Stir in the tender green beans, combining everything lovingly.
-
Assemble casserole: Pour the mixture into a greased 9×13 baking dish. Top generously with crispy fried onions, making sure every bite will have that satisfying crunch. Bake for 15 minutes, or until the top is beautifully golden brown. Serve warm and watch it disappear!
Optional: For an extra kick, sprinkle some crushed red pepper flakes before serving.

Dairy Free Green Bean Casserole Recipe FAQs
How do I choose the best green beans?
Absolutely! For the best flavor and texture, look for firm, vibrant green beans without dark spots or blemishes. They should snap easily when bent, indicating freshness. You want the beans to be tender but still have a nice crunch, so opt for those that are bright green and crisp.
How should I store leftovers of the casserole?
To store any leftovers, place them in an airtight container in the fridge. They will keep well for about 3 days. When you’re ready to enjoy them again, simply reheat in the oven at 350°F until warmed through and the topping regains its crispness.
Can I freeze my Dairy Free Green Bean Casserole?
Yes, you can! Before baking, wrap the assembled casserole tightly in plastic wrap followed by foil to prevent freezer burn. It will last for up to 2 months in the freezer.
How do I thaw and reheat a frozen casserole?
For the best results, thaw your casserole overnight in the refrigerator. Once thawed, preheat the oven to 350°F and bake until heated through, about 25-30 minutes. For a perfect crunchy topping, remove any covers for the last 5-10 minutes of baking.
What can I do if my sauce isn’t thickening?
No worries! If your creamy sauce isn’t thickening as expected, simply let it simmer on low heat for a few more minutes. This allows the flour to absorb the liquid better and can help achieve that luscious, creamy texture. If it still needs a boost, you can mix in a bit more flour—dissolve 1 tablespoon in a little water and stir it into the sauce, letting it simmer until thickened.
Are there any allergy considerations I should be aware of?
Yes! When preparing this Dairy Free Green Bean Casserole, ensure you’re using allergy-friendly ingredients. Opt for gluten-free flour if gluten is a concern, and always check the labels of your dairy-free milk and crispy onions to avoid any potential allergens for yourself or your guests. Always inform diners of what’s in the dish for safety!
