Preparing Green Bean Casserole
Making a delicious green bean casserole is easier than you might think! This classic dish is not just for the holidays; it’s perfect for any Sunday dinner or potluck. Getting started may feel overwhelming, but break it down into manageable steps, and you’ll be impressing your friends and family in no time!
Prepare the green beans
First things first—let’s prep those green beans! Start by trimming the ends of your 3 pounds of green beans. It's essential to remove those tough bit that can be a bit jarring in your casserole. Bring a large pot of generously salted water to a boil, and once it’s bubbling, drop in the green beans. Cook them for about 2 to 3 minutes, or until they’re bright green. The quick boil keeps them crisp and vibrant! When timing is critical, immediately transfer the beans to an ice bath using a slotted spoon or tongs. This will halt the cooking process and ensure they retain their beautiful color and crunch.
Sauté the onions and mushrooms
While your green beans cool, it’s time to add some flavor! In a large pot or saucepan, melt 4 tablespoons of unsalted butter over medium heat. Toss in 2 thinly sliced yellow onions and a generous pinch of salt. Sauté for about 7 minutes until they start to soften. Now, add 1 pound of sliced cremini mushrooms and continue to cook for another 7 minutes or until they're deliciously browned. Don't forget to stir occasionally! After that, throw in 4 cloves of finely chopped garlic, allowing it to cook until fragrant (about 1 minute). Season this mixture with fresh black pepper for an extra kick of flavor.
Make the creamy sauce
In the same pot, melt the remaining 8 tablespoons of butter over medium heat. Whisk in ½ cup of all-purpose flour and cook, whisking frequently, until it’s golden brown and smells toasty (about 3 minutes). Gradually add in 6 cups of whole milk, making sure to whisk continuously. Season with salt and pepper, then bring it to a simmer. Let it cook for another 4 minutes, stirring occasionally until it thickens up beautifully. This creamy sauce will be the heart of your green bean casserole!
Combine everything in a baking dish
Now for the fun part—combining everything! Add your sautéed onions and mushrooms to the large bowl with the green beans. Pour in the creamy sauce, stirring gently until all the ingredients are well combined. Transfer this delightful mixture into a 13" x 9" baking dish, making sure to spread it evenly.
Bake to perfection
Preheat your oven to 350°F and pop that casserole in! Bake for about 30 minutes until it’s warmed through and bubbly. For an irresistible crunch, remove it from the oven, sprinkle 1.5 cups of French's fried onions on top, and return it to the oven for another 5 minutes. This final step adds texture and flavor that will make your green bean casserole shine at your dinner table.
And there you have it! A crowd-pleasing dish that's ready to serve and sure to impress. If you’re looking for more tips on how to elevate your casserole game, check out Serious Eats, where they have incredible cooking insights!

Variations on Green Bean Casserole
Traditional vs. Modern Twists

You can also swap out green beans for roasted Brussels sprouts, blending tradition and innovation beautifully.
Vegetarian Options for a Healthier Dish
Looking for a more health-conscious take? You can keep the core of your green bean casserole intact while opting for a vegetarian version. Substitute the butter with olive oil and use a plant-based cream or cashew cream for the sauce. Also, try adding quinoa or lentils for added protein and texture. A sprinkle of nutritional yeast can give your dish that cheesy flavor without any dairy. These simple adjustments make for a deliciously wholesome dish that's perfect for any gathering.

Cooking tips and notes for Green Bean Casserole
Ensuring the perfect texture and flavor
To achieve the ideal green bean casserole, focus on the green beans first. Blanching them in boiling water locks in their vibrant color and crunch. A quick ice bath halts the cooking process, preserving their texture.
When sautéing onions and mushrooms, let them caramelize to enhance their natural sweetness—this adds depth to your dish. For a creamy sauce, whisk the flour well to avoid lumps; this technique helps maintain a smooth consistency. Lastly, topping with fried onions just before finishing baking adds that irresistible crunch. Enjoy making this flavorful comfort food!
