Classic Green Bean Casserole Recipe – Easy & Creamy!

Green Bean Casserole is more than just a side dish; it’s a heartwarming emblem of holiday gatherings and family traditions, a dish that instantly brings comfort and nostalgia to the table. Are you ready to elevate your festive spread or simply bring a beloved classic into your weeknight rotation?

This iconic dish holds a special place in American culinary history, famously created in 1955 by Dorcas Reilly at the Campbell Soup Company as an easy-to-make recipe that utilized common pantry staples. It quickly blossomed from a simple recipe card into an indispensable part of Thanksgiving and Christmas dinners across the nation. People adore this creamy, savory creation for its delightful blend of tender green beans, a rich, creamy mushroom sauce, and that utterly irresistible crispy fried onion topping that adds a perfect textural contrast. It’s the ultimate crowd-pleaser, easy enough for even novice cooks to master, yet impressive enough to satisfy everyone. My take on the classic Green Bean Casserole ensures that every spoonful delivers that perfect balance of flavors and textures we all crave, making it a guaranteed hit at any meal.

Ingredients:

• For the Green Beans:
  • 2 pounds fresh green beans, trimmed and snapped or cut into 1-inch pieces.
  • Alternatively, you can use two 14.5-ounce cans of cut green beans, drained very well, or two 10-ounce packages of frozen cut green beans. If using canned, rinse them under cold water before draining for best flavor.
  • 1 teaspoon salt (for blanching, if using fresh)
• For the Creamy Mushroom Sauce:
  • 4 tablespoons unsalted butter, divided
  • 8 ounces fresh cremini mushrooms (baby bellas), wiped clean and thinly sliced
  • 1 medium yellow onion, finely diced
  • 3 cloves garlic, minced
  • 1/2 teaspoon dried thyme
  • 1/4 cup all-purpose flour
  • 2 cups low-sodium chicken broth or vegetable broth
  • 1 cup whole milk or half-and-half (for extra richness, heavy cream can be used)
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon freshly ground black pepper, plus more to taste
  • Optional: 1/4 cup grated Parmesan cheese, for an extra layer of savory depth.
• For the Topping:
  • 1 (6-ounce) can crispy fried onions, divided
  • Optional: 1/4 cup finely chopped fresh parsley, for garnish after baking.

Preparation: Getting Everything Ready for Your Ultimate Green Bean Casserole

1. Prepare the Green Beans:

   If you’re using fresh green beans, which I highly recommend for the best texture in your Green Bean Casserole, you’ll want to blanch them first. Bring a large pot of generously salted water to a rolling boil. While the water is heating, prepare an ice bath in a large bowl (cold water and plenty of ice). Once the water is boiling, carefully add the trimmed green beans. Cook for 3-5 minutes, or until the beans are bright green and tender-crisp – you want them cooked through but still retaining a slight bite. Immediately transfer the beans with a slotted spoon or colander to the ice bath. This crucial step, known as shocking, stops the cooking process and helps preserve their vibrant color and crisp texture. Let them cool completely for a few minutes, then drain them very well and set aside. If using frozen green beans, thaw them completely and pat them dry. If using canned, simply drain them thoroughly and gently pat them dry.

2. Sauté the Mushrooms:

   Place a large, oven-safe skillet (preferably cast iron or a similar heavy-bottomed skillet that can go from stovetop to oven) or a Dutch oven over medium-high heat. Add 2 tablespoons of the unsalted butter. Once the butter is melted and shimmering, add the sliced mushrooms to the hot pan. It’s important not to overcrowd the pan; if necessary, cook them in two batches to ensure they brown nicely rather than steam. Cook, stirring occasionally, for 5-7 minutes, until the mushrooms have released their moisture and started to turn golden brown and caramelized. This browning develops a deep, umami flavor that is essential for a truly fantastic Green Bean Casserole. Once browned, remove the mushrooms from the pan and set them aside.

3. Cook the Aromatics:

   Reduce the heat to medium. Add the remaining 2 tablespoons of butter to the same skillet. Once melted, add the finely diced yellow onion. Sauté, stirring frequently, for about 5-7 minutes, until the onion has softened and become translucent. Next, add the minced garlic and dried thyme. Cook for another minute, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic, as burnt garlic can impart a bitter flavor to your creamy sauce.

Crafting the Creamy Sauce: The Heart of Your Green Bean Casserole

4. Make the Roux:

   Sprinkle the all-purpose flour over the softened onions and garlic in the skillet. Stir constantly for 1-2 minutes, cooking out the raw flour taste. This mixture, known as a roux, will thicken our sauce. It should form a thick paste and start to smell a little nutty. This step is critical for a smooth, lump-free sauce.

5. Whisk in Liquids:

   Gradually pour in the chicken or vegetable broth, whisking continuously to prevent lumps from forming. Start with a small amount, whisk until smooth, then add more. As the mixture heats, it will begin to thicken. Once all the broth is incorporated and the mixture is smooth and slightly thickened, slowly pour in the milk or half-and-half, continuing to whisk until fully combined and the sauce is creamy. Bring the sauce to a gentle simmer, whisking occasionally, and let it cook for 3-5 minutes, or until it reaches your desired consistency – it should be thick enough to coat the back of a spoon.

   Flavor Building for Your Creamy Green Bean Casserole Sauce:

   Now is the time to really build the flavor profile of our sauce. Stir in the Worcestershire sauce and Dijon mustard. These ingredients might seem unusual for a Green Bean Casserole, but trust me, they add incredible depth, umami, and a subtle tang that elevates the entire dish without being overtly noticeable themselves. Season the sauce with 1/2 teaspoon of salt and 1/4 teaspoon of freshly ground black pepper. Taste and adjust seasonings as needed. If you’re using it, stir in the optional 1/4 cup of grated Parmesan cheese now for an extra layer of savory goodness; it will melt beautifully into the warm sauce.

Assembly and Baking: Bringing Your Green Bean Casserole to Life

6. Combine Ingredients:

   Preheat your oven to 375°F (190°C). Gently fold the blanched (or thawed/drained) green beans and the sautéed mushrooms into the creamy sauce in the skillet. Stir until everything is thoroughly combined and coated in the luscious sauce. If your skillet isn’t oven-safe, transfer the mixture to a 9×13-inch baking dish or an equivalent 3-quart casserole dish that has been lightly greased. Make sure the green beans are evenly distributed.

   Why Even Distribution Matters for a Perfect Green Bean Casserole:

   An even layer ensures that every bite has a wonderful balance of beans and creamy sauce, and that the heat penetrates consistently for perfect cooking. This attention to detail will ensure your Green Bean Casserole is a hit!

7. First Bake:

   Place the casserole in the preheated oven. Bake for 20-25 minutes, or until the casserole is bubbly around the edges and heated through. You might see the sauce gently simmering, which is exactly what we want. This initial bake allows the flavors to meld beautifully and the casserole to achieve that wonderful creamy texture throughout.

8. Add the Crispy Topping:

   Remove the Green Bean Casserole from the oven. Carefully sprinkle about two-thirds of the crispy fried onions evenly over the top of the casserole. This layer will become delightfully crisp and golden brown in the final bake, providing a crucial textural contrast to the soft beans and creamy sauce. The aroma filling your kitchen right now will be absolutely mouth-watering!

9. Final Bake:

   Return the casserole to the oven and continue baking for another 8-12 minutes, or until the crispy fried onions are golden brown and toasted. Keep a close eye on them during this phase, as they can burn quickly. You want them perfectly crunchy and deeply flavorful. This final touch makes the Green Bean Casserole truly iconic.

10. Rest and Serve:

    Once baked to perfection, remove the Green Bean Casserole from the oven. Let it rest for 5-10 minutes before serving. This brief resting period allows the sauce to set slightly, making it easier to serve and preventing it from being too runny. Before serving, you can optionally sprinkle the remaining one-third of the crispy fried onions over the top for an extra fresh crunch, and a garnish of fresh parsley can add a lovely touch of color and freshness. Enjoy your homemade, incredibly flavorful Green Bean Casserole!

Unleash Your Inner Chef: Creative Variations!

While this classic Green Bean Casserole recipe stands strong on its own, I always encourage you to unleash your inner chef and experiment with variations to make it uniquely yours! For an extra layer of richness, consider adding a pinch of freshly grated nutmeg to the creamy sauce. If you’re a cheese lover (and who isn’t?), stirring in half a cup of shredded Gruyère or sharp cheddar cheese to the sauce before baking will give it an incredible cheesy pull and a deeper flavor profile. Want to add a touch of gourmet flair? Sauté some thinly sliced mushrooms along with your onions for an earthy undertone. For a smoky twist, crumble some crispy bacon bits into the casserole before baking, or even mix them into the topping. You could also experiment with different crispy toppings – perhaps a homemade panko breadcrumb topping seasoned with garlic powder and Parmesan, or even crushed Ritz crackers for a buttery crunch. For those mindful of dietary needs, a gluten-free cream of mushroom soup alternative or a homemade béchamel with a gluten-free flour blend works wonderfully, and for a dairy-free version, a cashew cream base can provide a remarkably similar texture and richness. The possibilities are truly endless, and each variation offers a chance to personalize this beloved dish.
