Ingredients
The essence of this Green Bean Casserole lies in the quality and combination of its ingredients. Here’s what you’ll need:
- Green Beans: 1 pound, preferably fresh for that snap and vibrant color. If using canned, reduce cooking time.
- Cremini Mushrooms: 8 oz, sliced. Offers an earthy depth, more robust than white mushrooms.
- Onion: 1 medium, finely chopped. A sweet past and creamy finish arises as it caramelizes.
- Garlic Cloves: 3 cloves, minced. Enhances the dish’s aromatics and flavor layer.
- Milk: 1 cup. Whole milk provides a creamier texture, while skim can be used for a lighter variant.
- Butter: 2 tablespoons for richness and flavor foundation.
- Flour: 2 tablespoons. A necessity for thickening the creamy sauce.
- Chicken Broth: 1 cup. If vegan, substitute with vegetable broth.
- Parmesan Cheese: 1/2 cup, grated. Infuses umami and creamy goodness into the dish.
- Fried Onions: 1 cup. Provides the signature crunchy topping.
- Salt and Pepper: To taste—fundamental for balancing flavors.
Ingredient Insight: If you’re lactose intolerant or following a vegan diet, consider swapping the milk for almond or oat milk, and the cheese for nutritional yeast or a vegan cheese alternative.
Step-by-Step Instructions
Now that you’re equipped with your ingredients, let’s dive into the assembly of this delectable dish designed to wow your guests and family:
- Prepare the Green Beans: Blanch them in a pot of boiling water for about 3-4 minutes until bright green and tender-crisp. Use a slotted spoon to transfer them into a bowl of ice water to stop the cooking process. Drain thoroughly.
- Sauté the Aromatics: In a large skillet over medium heat, melt the butter. Add the onions and cook until translucent, about 5 minutes. Incorporate the mushrooms and garlic, sautéing until the mushrooms are soft and any moisture has evaporated.
- Create the Sauce: Sprinkle the flour over the sautéed vegetables, stirring continuously for about 1 minute. Gradually whisk in the chicken broth and milk, simmering until the mixture thickens. Stir in the Parmesan cheese until melted, seasoning with salt and pepper as desired.
- Combine and Bake: Preheat your oven to 350°F (175°C). In a large baking dish, combine the green beans with the creamy mushroom sauce, mixing well. Top with a generous layer of fried onions.
- Finish the Dish: Bake for 20-25 minutes, or until the dish is heated through and the fried onions are golden brown and crispy.
Expert Tips
While creating this family favorite, I discovered a few tips to enhance the dish’s flavor and simplify the process:
- Make Ahead: You can prepare the casserole a day in advance, omitting the fried onions until just before baking to keep them crispy.
- Fresh vs. Canned: Opt for fresh green beans to elevate the dish’s texture and flavor, but if pinched for time, canned beans are a viable alternative.
- Vegetarian Option: Substitute chicken broth with vegetable broth to accommodate vegetarian preferences without compromising taste.
- Add a Kick: Spice it up by adding a pinch of cayenne pepper to the mushroom sauce for some mild heat.
FAQ
Can I make this casserole gluten-free?
Absolutely! Substitute the all-purpose flour with gluten-free flour, and ensure all other ingredients, especially the fried onions, are gluten-free.
How can I store leftovers?
Transfer any leftovers to an airtight container and refrigerate for up to 3 days. Reheat in the oven at 350°F for 10-15 minutes or until heated through.

Certainly! Diced cooked chicken, turkey, or even a plant-based protein like tofu can be mixed in with the green beans before baking.

Only add the fried onions just before serving or reheating. If reheating leftovers, you can add a fresh layer of fried onions to maintain the crunch.
