Ingredients.

Green Beans. You're welcome to use fresh or canned here! I'll provide instructions for both below. No judgement. I prefer french style canned green beans.
Olive Oil. A healthy fat alternative to butter.
Yellow Onion. Onions add rich flavor and nutrients like Vitamin C, flavonoids, and sulfur compounds known to fight cancer.
Flour. Gluten free 1:1 flour if you need the gluten free option.
Fried Onions. Gluten free if needed. I buy mine at Sprouts.
Mushrooms. Mushrooms are low calorie but high in nutrients like fiber, pre-biotics and vitamin D. They also add a major umami flavor that gets lost in the traditional Campbell's green bean casserole.
Garlic. Garlic makes every dish better.
Soy Sauce. Choose a Gluten free soy sauce if making gluten free.
Milk of choice. I love Elmhurst Cashew milk for baking rich and creamy dishes.
Spices. Black pepper, salt, and - the secret ingredient that makes my easy green bean casserole next level -white pepper.

Subs and Variations?

Make it Gluten free. You'll need to choose gluten free fried onions, soy sauce, and flour.

Make it Dairy free. Use a dairy free milk.

This French green bean casserole combines elegance with nostalgia, making it a standout choice for any festive spread. It’s one of the best Thanksgiving sides because it’s both delicious and accommodating for dietary needs. Plus, the homemade sauce creates a creamy and flavorful dish that outshines the canned-soup version.

Pair it with turkey, stuffing, and other easy side dishes to complete your holiday meal. Whether you’re serving a crowd or creating a cozy celebration, this easy holiday side dish is sure to impress.

Make it ahead: I specifically love this dish, because it's easy to prep ahead of time! Just prep the casserole, stopping before you top it with crispy fried onions. Store the casserole in your serving dish (covered) in the fridge up to 2 days prior. When you're ready to serve, top with crispy onions and bake for 20 minutes. Voila.
