Green Bean Casserole Ingredients

For the Casserole

  • Fresh green beans – Provides a vibrant and crisp base for the casserole; you can substitute frozen green beans by thawing and patting them dry.
  • Butter (unsalted) – Adds richness and flavor to the sauce; use margarine for a dairy-free option.
  • Yellow onion – Imparts sweetness and depth to the dish; shallots can replace it for a milder flavor.
  • White mushrooms – Adds umami and texture; cremini mushrooms are a flavorful alternative.
  • Garlic – Enhances flavor in the sauce; fresh garlic is recommended, but garlic powder works in a pinch.
  • All-purpose flour – Acts as a thickener for the sauce; for a gluten-free version, swap in gluten-free flour.
  • Chicken or vegetable broth – Provides savory flavor for the sauce; opt for low-sodium varieties to control saltiness.
  • Heavy cream – Creates a luxurious, rich sauce texture; use coconut milk or almond milk for a dairy-free alternative (add extra flour for thickness).
  • Kosher salt – Enhances all flavors of the dish; adjust according to your taste.
  • Freshly ground black pepper – Adds a touch of spice and freshness.

For the Topping

  • Crispy fried onions – Provides vital crunch and texture; add half before baking and the rest in the last few minutes for optimal crispness.

Step‑by‑Step Instructions for Creamy Green Bean Casserole That Everyone Will Love

Step 1: Blanch Green Beans
Start by bringing a large pot of salted water to a rolling boil over high heat. Add the fresh green beans and cook them for just 3 minutes—this will keep them vibrant and crisp! Once cooked, drain the beans in a colander and immediately rinse them under cold water to stop the cooking process. Pat the green beans dry to ensure they don’t release excess moisture in your casserole.

Step 2: Prepare the Creamy Sauce
In a large skillet, melt 4 tablespoons of unsalted butter over medium heat. Add the chopped yellow onion and sauté for 3 minutes until it’s translucent and fragrant. Then, toss in the sliced white mushrooms and minced garlic, cooking for an additional 5 to 7 minutes until the mushrooms soften and release their juices. Sprinkle in the all-purpose flour, stirring for 1 minute until well combined, creating a roux.

Step 3: Make It Creamy
Gradually whisk in 1 cup of chicken or vegetable broth along with 1 cup of heavy cream. Keep stirring as the mixture thickens, which should take about 3 to 5 minutes. As the cream sauce develops, season with kosher salt and freshly ground black pepper to taste. Allow the sauce to bubble gently for that perfect creamy consistency, ensuring it’s well-seasoned before mixing with the green beans.

Step 4: Assemble and Bake
In a large mixing bowl, combine the blanched green beans with the creamy sauce, stirring gently to coat each bean. Transfer this glorious mixture into a greased baking dish, spreading it evenly. Sprinkle half of the crispy fried onions over the top for that added crunch, then place the dish in a preheated oven at 350°F (175°C). Bake for 20 minutes or until the casserole is bubbling and golden brown at the edges.

Step 5: Final Touches
After 20 minutes of baking, remove the casserole from the oven and add the remaining crispy fried onions on top for a delightful crunch. Return it to the oven for an additional 5 minutes to ensure they crisp up perfectly. Once it’s beautifully golden and aromatic, take it out and let it rest for 5 minutes before serving—this will help the sauce set up slightly for easier serving.

Green Bean Casserole Variations
