Ingredients You’ll Need

To make a great Green Bean Casserole from scratch, you’ll need:

Fresh Ingredients

• Green Beans (1 lb): Fresh or frozen work best. Trim and cut into bite-sized pieces.
• Mushrooms (8 oz): Sliced, preferably white or cremini for a natural umami flavor.
• Onion (1 small): Thinly sliced for layering and crispy topping.
• Garlic (2 cloves): Minced to enhance the creamy sauce.

Pantry Staples

• Cream of Mushroom Soup (1 can): For a quick version, but homemade is even better.
• Milk (1/2 cup): Lightens the sauce, creating the desired creamy consistency.
• Fried Onions (1 1/2 cups): The ultimate crispy topping for the casserole.
• Seasonings: Salt, pepper, and optional cayenne for a subtle kick.

How to Make Green Bean Casserole in Six Simple Steps

1. Blanch the Green Beans

For a vibrant green color and perfect texture, blanch your fresh green beans. Bring a large pot of salted water to a boil, add the beans, and cook for 3-4 minutes. Immediately transfer them to an ice bath to stop the cooking process. Drain and set aside.

Pro Tip: Blanching ensures the beans stay tender-crisp and don’t get overcooked during baking.

2. Prepare the Creamy Mushroom Sauce

• Heat a pan over medium heat with a splash of olive oil or butter and sauté onions, garlic, and sliced mushrooms until softened.
• Stir in cream of mushroom soup and milk, cooking until the mixture is bubbling and thickened. Season with salt, pepper, and cayenne for added depth.

Pro Tip: For a homemade alternative, substitute the canned soup with a roux using butter, flour, milk, and fresh mushrooms.

3. Combine and Layer in a Dish

• Preheat your oven to 350°F (175°C).
• Mix the blanched green beans with the creamy mushroom sauce in a large bowl.
• Transfer the mixture to a greased casserole dish. Evenly distribute two-thirds of your fried onions on top of the mixture for a base layer of crunch.

4. Bake Until Bubbly

Place the casserole in the preheated oven and bake uncovered for 20-25 minutes, or until the edges are bubbly and golden. Watch closely to avoid over-browning.

5. Add the Final Crispy Topping

Remove the casserole from the oven and top with the remaining fried onions. Return to the oven for an additional 5 minutes, allowing the onions to crisp up beautifully.

6. Serve and Enjoy

Take the Green Bean Casserole out of the oven, and allow it to cool slightly before serving. Garnish with freshly cracked pepper or parsley for extra flair. Serve alongside roast meats, mashed potatoes, or as part of your festive spread.

Pro Tip: For extra texture, consider adding crispy bacon bits or slivered almonds as toppings.

Variations for Every Palate

One of the best things about Green Bean Casserole? It can flex to match your preferences:

• Health Conscious: Swap fried onions for crispy panko breadcrumbs and use low-fat or plant-based cream.
• Vegan-Friendly: Opt for plant-based milk, vegan cream soup, and fried shallots instead of fried onions.
• Cheesy Lovers: Mix shredded Parmesan or sharp cheddar into the creamy mushroom mixture.
