Ingredients

Scale
  • 2 pounds fresh green beans, trimmed and snapped
  • 1/2 cup unsalted butter
  • 1 medium yellow onion, finely chopped
  • 8 ounces sliced mushrooms (cremini or white button)
  • 1/2 cup all-purpose flour
  • 2 cups chicken broth (low sodium)
  • 1 cup heavy cream
  • 1 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt, or to taste
  • 1 (6 ounce) can crispy fried onions, divided

  • Instructions

    1. Prepare the Green Beans: Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for 5-7 minutes, or until they are tender-crisp. You want them bright green and slightly softened but still with a little bite. Drain them immediately and plunge them into an ice bath to stop the cooking process. This helps retain their vibrant color and crisp texture. Once cooled, drain thoroughly and set aside.

    2. Saute Aromatics and Mushrooms: In a large oven-safe skillet or Dutch oven, melt the butter over medium heat. Add the finely chopped yellow onion and cook for 3-5 minutes until it softens and becomes translucent. Add the sliced mushrooms and continue to cook for another 5-7 minutes, stirring occasionally, until the mushrooms release their liquid and start to brown.

    3. Create the Roux: Sprinkle the all-purpose flour over the cooked onions and mushrooms. Stir constantly for 1-2 minutes to cook out the raw flour taste, creating a roux. It should form a thick paste.

    4. Whisk in Liquids and Seasonings: Gradually whisk in the chicken broth, a little at a time, ensuring no lumps form. Once all the broth is incorporated, slowly whisk in the heavy cream. Bring the mixture to a gentle simmer, stirring constantly, until the sauce thickens to a creamy consistency. Season with garlic powder, black pepper, and salt. Taste and adjust seasoning as needed.

    5. Combine and Bake: Gently stir the blanched green beans into the creamy mushroom sauce. Fold in about two-thirds of the crispy fried onions. Pour the mixture into a 9×13 inch baking dish if not using an oven-safe skillet.

    6. Final Bake: Bake in a preheated oven at 375 F (190 C) for 20-25 minutes, or until the casserole is bubbly around the edges. Remove from the oven, sprinkle the remaining crispy fried onions over the top, and return to the oven for another 5 minutes, or until the onions are golden brown and crisp. Serve hot.

    INGREDIENTS:

    • 2 pounds fresh green beans, trimmed and snapped
    • 1/2 cup unsalted butter
    • 1 medium yellow onion, finely chopped
    • 8 ounces sliced mushrooms (cremini or white button)
    • 1/2 cup all-purpose flour
    • 2 cups chicken broth (low sodium)
    • 1 cup heavy cream
    • 1 teaspoon garlic powder
    • 1/2 teaspoon black pepper
    • 1/2 teaspoon salt, or to taste
    • 1 (6 ounce) can crispy fried onions, divided

    For simple substitutions, you can use frozen green beans if fresh aren’t available; just make sure to thaw and drain them well before cooking. If you prefer a vegetarian option, vegetable broth can easily replace chicken broth. For the mushrooms, any variety will work, or you can omit them if you’re not a fan. If you don’t have heavy cream, whole milk can be used for a slightly lighter sauce, though it won’t be quite as rich. When it comes to crispy fried onions, feel free to use your favorite brand; they are a key textural component of the dish.

    Easy Variations And Serving Ideas That Fit Real Life

    This homemade green bean casserole is wonderfully versatile, allowing for easy adaptations to suit different tastes and occasions. It’s a fantastic side dish that can complement a wide range of meals, from a casual family dinner to a festive holiday spread.

    For a kid-friendly twist, you can add a sprinkle of shredded cheddar cheese to the top along with the fried onions during the last 5 minutes of baking. The melting cheese adds a fun, gooey element that many children love. If you want to introduce another layer of flavor, a pinch of smoked paprika or a dash of Worcestershire sauce can be added to the creamy sauce. For a heartier casserole, consider adding some cooked, crumbled bacon or diced ham to the mix along with the green beans.

    When serving for a party or buffet, this casserole holds up well, making it an excellent make-ahead option. It pairs beautifully with roasted chicken, turkey, ham, or even a simple pot roast. Don’t limit it just to holidays; it’s a comforting side dish that works perfectly with weeknight meals. You can also serve it alongside mashed potatoes and cranberry sauce for a classic holiday plate. For a little extra zing, a squeeze of fresh lemon juice over the top just before serving can brighten all the flavors.

    Common Slip-Ups And How To Avoid Them

    Even with a straightforward recipe like green bean casserole, a few common mistakes can impact the final outcome. Being aware of these can help you achieve perfect results every time.

    One frequent slip-up is overcooking the green beans in the initial blanching step. If they become too soft, they’ll turn mushy during baking. Aim for tender-crisp; they should still have a slight snap. The ice bath is crucial for stopping the cooking process and preserving their vibrant color and texture. Another common error is not cooking the flour long enough when making the roux. A raw flour taste can detract from the creaminess of the sauce. Make sure to stir the flour with the butter and onions for at least 1-2 minutes until it smells slightly nutty.

    Lumpy sauce is another pitfall. To avoid this, always whisk in the broth and cream gradually, adding a small amount at a time and whisking until smooth before adding more. This ensures a silky, lump-free sauce. Finally, don’t forget to season properly. Taste the sauce before adding the green beans and adjust salt and pepper as needed. Sometimes, the broth can be salty, so start with less and add more to taste. Over-baking the casserole can also dry it out, especially the fried onions. Keep an eye on it during the final bake, removing it once it’s bubbly and the onions are golden brown, not burnt.

    How To Store It And Make It Ahead Without Ruining Texture

    Proper storage and make-ahead techniques can help you enjoy this delicious green bean casserole even more, whether you’re planning for a holiday or just want leftovers.

    To store leftovers, allow the casserole to cool completely to room temperature. Then, transfer it to an airtight container and refrigerate for up to 3-4 days. For reheating, you can warm individual portions in the microwave until heated through. For a larger amount, place the casserole back into an oven-safe dish, cover it loosely with foil, and reheat in a preheated oven at 300°F (150°C) for 15-20 minutes, or until warm
