This recipe is brought to you by Alexia Foods

Green bean casserole is a classic holiday side dish, that’s right up there with stuffing, gravy, and cranberry sauce. So why go and change it? It’s true, sometimes you just shouldn’t mess with the classics, especially when they’re tied to food memories of time spent with family. But times change, and tastes evolve. The last time I was passed an 11×13-inch casserole dish of green bean casserole, it was a sad mixture of stunted, pallid beans in a gloopy grey gravy instead of a flavorful sauce. I knew I could give this dish the makeover it deserved.The original green bean casserole was created during the era of home cooks transitioning from scratch-made meals to relishing in the convenience that cooking from a box or can delivers. To be fair, I’m the first one to raise my hand when it comes to saving time in the kitchen. The only exception? I won’t sacrifice flavor. That’s why you won’t find any cream of mushroom soup or canned green beans in my recipe. I’ve created an easy recipe that combines real, fresh ingredients with lots of flavors, while still saving you time. Everyone (especially me) is happy at the table.

What’s in This Green Bean Casserole

To make the best green bean casserole recipe possible, I used only a handful of real, simple ingredients. Here’s what you need to make this green bean casserole:

Fresh green beans —The original green bean casserole calls for canned green beans or frozen green beans. While flash-frozen green beans are a good option because they retain their nutrients, I use fresh green beans because I simply prefer the taste and texture. No mushy green beans here!

Better creamy mushroom sauce — Instead of using high-sodium canned cream of mushroom soup, I make my super easy standard white sauce where I can control how much salt goes into it. It’s flavored with fresh, sautéed mushrooms and onions with a bit of fresh thyme. I don’t use garlic in my green bean casserole, but if you wanted, you totally could. I’d suggest mincing 1 or 2 cloves.

The white sauce ingredient ratios are easy to remember —2 tablespoons butter, 2 tablespoons flour, and 2 cups milk or vegetable or chicken broth = 2:2:2.

A better crunchy topping — One of the signature flavors of le casserole de green bean is the crispy crunchy topper, and this is where I add another spin to the original recipe and use chef-inspired All Natural Alexia Crispy Onion Rings. I’m a big fan of onion rings, but I want them thick and crunchy, and not greasy—and these rings deliver.

How to Make This Green Bean Casserole

Shock the green beans. To take the raw edge off, shock the fresh green beans in boiling water for a minute or two, or until they turn bright green, then drain.

Bake the frozen onion rings for 10 minutes. Set them aside until you’re ready to assemble the green bean casserole.

Sauté the onion and mushrooms. While the onion rings bake, sauté the chopped onion in a buttered skillet, just until they turn translucent. Add the mushrooms to the same skillet, along with the salt, black pepper, and thyme, and continue cooking until they’re tender.

Get saucy. Add flour, milk, chicken stock, and nutmeg to the skillet and cook it down to create a creamy white sauce. Stir in the green beans, then transfer the green bean mixture to a baking dish and add the baked onion rings on top.

Bake until bubbly. Bake the green bean casserole until the top is lightly browned and the casserole is starting to bubble around the edges.

How do You Keep Green Bean Casserole From Getting Mushy

The biggest way to prevent your green bean casserole from getting mushy is to take care not to overcook your green beans. You want tender green beans that still have a bite to them. Overcooking them will give you sad and soggy beans.

Are You Supposed to Cover Green Bean Casserole When Baking

There’s no need to cover this green bean casserole recipe, but if for some reason you find it’s getting too brown, feel free to tent it with some aluminum foil.

How to Reheat Green Bean Casserole

If you wind up with leftovers of this green bean casserole from scratch, you’ll want to reheat them in the oven at 350ºF. Don’t microwave leftover green bean casserole, or the green beans and onion rings will be rubbery.

Can You Make Green Bean Casserole Ahead of Time?

Yes, simply follow the recipe up to the point of baking (but hold the onion rings). Cover and refrigerate up to overnight. When you’re ready to bake, add the onion rings (otherwise they’ll get mushy and soggy). Note that your casserole may need a bit longer in the oven.

Can You Freeze Green Bean Casserole?

I don’t recommend freezing green bean casserole. The onion rings will lose their crispness, and the casserole itself will likely be quite mushy once reheated.

How Many Days is Green Bean Casserole Good For?

This green bean casserole from scratch will keep in the refrigerator for about 4 or 5 days.

Tips for Making the Best Green Bean Casserole

Instead of blanching the green beans, you could also steam them for a minute or so in the microwave with a tablespoon or two of water. Use the frozen variety if you prefer, just be sure to thaw and drain the excess water so your casserole doesn’t get runny.

When making the white sauce, add more chicken stock (this one’s my FAVORITE!) if you prefer a thinner sauce. For even more flavor, add white wine. Choose a white wine you’d actually drink, not one labeled as cooking wine.

Also, for the creamiest, most flavorful white sauce uses whole milk or half and half. Don’t use 2% or skim milk here, otherwise, your sauce won’t thicken up properly and your green bean casserole will be a runny mess. I don’t use any cheese in mine, but if you wanted, cheddar cheese would be an excellent addition to the sauce.

Calories 105kcal


  • 1 pound green beans fresh or frozen
  • 1 11- ounce bag Alexia Crispy Onion Rings with Panko Breading and Sea Salt
  • 2 tablespoons butter
  • ½ cup chopped onion
  • 10 ounces brown cremini mushrooms sliced, about 4 cups
  • 1 ½ teaspoons kosher salt divided
  • ½ teaspoon freshly ground black pepper
  • ½ teaspoon fresh thyme
  • 2 tablespoons all-purpose flour
  • 2 cups whole milk or half and half
  • ½ cup white wine or chicken stock
  • ½ teaspoon ground nutmeg


  • Trim the green beans and cut in half, then place in a microwave-safe bowl with 2 tablespoons water and cook for 3 minutes. Drain, and set aside. If using frozen, thaw in the microwave or on the counter and drain any excess water.

  • Preheat the oven to 400°F and line a baking sheet with aluminum foil. Place the onion rings on the tray and bake for 10 minutes or until the onion rings are crisp. Set aside.

  • While the onion rings are baking, melt the butter in a large skillet over medium heat and add the onions. Cook the onions for 3-5 minutes or until they begin to soften and become translucent.

  • Add the sliced mushrooms and season with 1 teaspoon of the kosher salt, black pepper, and thyme. Cook, stirring occasionally, for about 5 minutes or until the mushrooms are tender.

  • Sprinkle the mixture with the flour, stir to combine, and cook for 1-2 minutes, stirring so the flour doesn't burn but does cook out the flour-y taste. Add the milk or half and half, wine or chicken broth, and the nutmeg and cook for 4-5 minutes, stirring, or until the sauce has reduced by half.

  • Remove the sauce from the heat and stir in the green beans. Transfer half of the bean mixture to a 2-quart casserole dish, or 11 x 7- or 8-inch square baking dish and top with half of the onion rings, then the rest of the beans and top with the remaining onion rings.

  • Bake for 10-15 minutes or until the top is lightly browned and the sauce is bubbly. Let sit for 5-10 minutes, the sauce will thicken as it cools.

Green Bean Casserole

Green bean casserole is a classic holiday side dish that is often served during Thanksgiving. It traditionally consists of green beans, cream of mushroom soup, and crispy fried onions. However, this article offers a homemade version that uses fresh green beans and a homemade mushroom sauce, topped with crispy onion rings.

Fresh Green Beans

Fresh green beans are used in this recipe instead of canned or frozen green beans. The author mentions that they prefer the taste and texture of fresh green beans and that they don't become mushy when cooked properly.

Homemade Mushroom Sauce

Instead of using canned cream of mushroom soup, the author makes a homemade mushroom sauce for the green bean casserole. The sauce is made with sautéed mushrooms, onions, butter, flour, milk (or vegetable/chicken broth), and seasonings like salt, black pepper, and thyme. This allows for more control over the flavors and sodium content of the dish.

Crispy Onion Rings

One of the signature flavors of green bean casserole is the crispy onion topping. In this recipe, the author uses All Natural Alexia Crispy Onion Rings to add a crunchy texture and savory taste to the casserole. These onion rings are baked in the oven until crispy before being added to the dish.

Cooking Process

The recipe involves several steps to make the green bean casserole. These include blanching the green beans to remove the raw edge, baking the onion rings separately to make them crispy, sautéing onions and mushrooms to create the mushroom sauce, combining the sauce with the green beans, and baking the casserole until bubbly and lightly browned.

Tips and Variations

The article also provides some tips and variations for making the best green bean casserole. These include using steamed green beans instead of blanching, adjusting the thickness of the sauce by adding more chicken stock or white wine, using whole milk or half and half for a creamier sauce, and adding cheddar cheese for additional flavor.

Storage and Reheating

The article mentions that the green bean casserole can be made ahead of time and refrigerated overnight before baking. Leftovers can be reheated in the oven at 350°F. Freezing the casserole is not recommended as it may lead to loss of texture and crispness.

I hope this information helps you understand the concepts and techniques used in the article about the green bean casserole. Let me know if there's anything else I can assist you with!
