What is Green Bean Casserole?

Green Bean Casserole is a creamy, savory, and crunchy side dish that has been a staple at holiday tables for generations. Made with green beans, a creamy sauce, and crispy fried onions, it’s a simple yet flavorful dish that pairs well with turkey, ham, or any comforting main course.

The History of Green Bean Casserole

This beloved casserole was originally created in 1955 by Dorcas Reilly, a home economist at Campbell’s Test Kitchen. Her goal was to develop a simple, affordable, and delicious recipe using ingredients most households had on hand. By combining canned green beans, Campbell’s cream of mushroom soup, and crispy fried onions, she created a dish that quickly became a Thanksgiving classic.

Why is it So Popular?

The appeal of Green Bean Casserole comes from its delicious contrast of textures and flavors—the tender green beans, creamy mushroom sauce, and crispy onion topping create the perfect bite. Plus, it’s incredibly easy to make, requiring just a few ingredients and minimal prep time.

Traditional Ingredients

The classic version of Green Bean Casserole includes:

• Green beans (fresh, frozen, or canned)
• Cream of mushroom soup for a rich, creamy base
• Milk to thin out the sauce and create the perfect consistency
• Fried onions for a crispy, flavorful topping
• Salt, pepper, and optional seasonings to enhance the dish

Despite its humble beginnings, Green Bean Casserole has evolved into a must-have holiday side dish, with countless variations that allow for personalization and modern twists. Now, let’s take a closer look at the essential ingredients needed to make the best Green Bean Casserole.

Essential Ingredients for Easy Green Bean Casserole

To make the perfect easy Green Bean Casserole, you’ll need just a few simple ingredients. Here’s what you’ll need:

• 4 cups green beans – Fresh, frozen, or canned (drained)
• 1 can (10.5 oz) cream of mushroom soup – The classic creamy base
• ¾ cup milk – Helps create a smooth sauce
• 1 teaspoon soy sauce (optional) – Enhances umami flavor
• ½ teaspoon garlic powder (optional) – Adds extra depth
• ½ teaspoon salt – Adjust based on preference
• ¼ teaspoon black pepper – Adds a hint of spice
• 1 ½ cups crispy fried onions – The essential crunchy topping

Fresh, Frozen, or Canned Green Beans?

One of the biggest decisions when making Green Bean Casserole is choosing the right type of green beans. Each option has its benefits:

• Fresh Green Beans – Provide the best texture and flavor but require blanching before baking to keep them tender-crisp.
• Frozen Green Beans – A great middle-ground option that retains good texture without extra prep. Simply thaw before use.
• Canned Green Beans – The easiest and fastest option, but they’re softer and should be drained well to avoid a watery casserole.

Cream of Mushroom Soup: Store-Bought vs. Homemade

Campbell’s Cream of Mushroom Soup is the traditional choice for this recipe, but if you prefer to make a homemade version, you can substitute it with a quick, creamy mushroom sauce using:

• 1 cup heavy cream or whole milk
• ½ cup sautéed mushrooms
• 1 tablespoon butter
• 1 tablespoon flour (to thicken)
• Salt and pepper to taste

Simply cook these ingredients together until thickened and use them in place of canned soup.

Why Fried Onions Are Essential

The crispy fried onions on top are what make this dish truly iconic. They add crunch, saltiness, and a burst of flavor to every bite. While store-bought crispy onions (such as French’s Crispy Fried Onions) are the easiest option, you can also make homemade fried onions by lightly breading and frying thinly sliced onions in oil.

With the ingredients ready, let’s move on to the step-by-step guide to assembling and baking the perfect Green Bean Casserole.

Step-by-Step Guide to Making Easy Green Bean Casserole

Making Green Bean Casserole is quick and simple, requiring just a few steps. Follow this guide to ensure a perfectly creamy and crunchy casserole every time.

1. Preheat the Oven

Set your oven to 350°F (175°C). This ensures the casserole bakes evenly and the flavors meld together perfectly.

2. Prepare the Green Beans

• For fresh green beans: Trim the ends and blanch them in boiling water for 3–4 minutes, then drain and pat dry. This keeps them tender but not mushy.
• For frozen green beans: Thaw completely and pat dry with a paper towel to remove excess moisture.
• For canned green beans: Drain well and pat dry to avoid a watery casserole.

3. Make the Creamy Base

In a large mixing bowl, combine:

• Cream of mushroom soup
• Milk
• Soy sauce (optional, for extra depth of flavor)
• Garlic powder, salt, and black pepper

Stir everything together until the mixture is smooth and well combined.

4. Assemble the Casserole

• Add the prepared green beans to the mixing bowl and stir to coat them evenly in the creamy mixture.
• Transfer the mixture to a lightly greased 9×13-inch baking dish, spreading it out evenly.

5. Bake Until Heated Through

Place the casserole in the preheated oven and bake for 25 minutes, or until the sauce is bubbling around the edges.

6. Add the Crispy Fried Onions

Remove the casserole from the oven and sprinkle the crispy fried onions evenly over the top. This ensures they stay crunchy instead of getting soggy.

7. Bake Again for a Crispy Topping

Return the casserole to the oven for an additional 5–7 minutes, or until the onions are golden brown and crisp.

8. Serve & Enjoy

Let the casserole rest for a few minutes before serving. This allows the flavors to settle and makes it easier to scoop. Serve warm as a holiday side dish or comforting weeknight meal.

Now that you’ve mastered the classic Green Bean Casserole, let’s explore some delicious variations and ingredient swaps!

Green Bean Casserole Variations & Substitutions

While the classic Green Bean Casserole is always a hit, there are plenty of ways to customize it to fit different dietary needs and flavor preferences. Whether you want to add extra richness, make it dairy-free, or give it a smoky twist, these variations will take your casserole to the next level.

Classic Green Bean Casserole

The traditional recipe includes green beans, cream of mushroom soup, milk, and crispy fried onions. This version is perfect for those who love the classic holiday staple without any major changes.

Cheesy Green Bean Casserole

For a richer, cheesier version, stir in 1 cup of shredded cheddar cheese into the creamy mixture before baking. You can also sprinkle extra cheese on top before adding the fried onions for a golden, bubbly crust. Parmesan, mozzarella, or even Gruyère are great options for a more gourmet touch.

Bacon Green Bean Casserole

For a smoky, savory twist, add crispy bacon to your casserole. Simply cook 6–8 slices of bacon, crumble them, and mix them into the green bean and sauce mixture before baking. You can also sprinkle extra bacon on top along with the crispy onions for added crunch.

Dairy-Free or Vegan Green Bean Casserole

To make this dish dairy-free, swap out traditional ingredients for plant-based alternatives:

• Use a dairy-free cream of mushroom soup (homemade or store-bought).
• Substitute milk with almond milk, cashew milk, or oat milk.
• Use a vegan butter alternative if making homemade mushroom sauce.
• Try crispy fried shallots instead of store-bought fried onions, which may contain dairy-based coatings.

Gluten-Free Green Bean Casserole

For a gluten-free version, make these swaps:

• Use gluten-free cream of mushroom soup (available at most grocery stores or make your own).
• Replace traditional fried onions with gluten-free crispy onions or toasted gluten-free breadcrumbs.
• Use cornstarch instead of flour if making homemade sauce.

Spicy Green Bean Casserole

For a little heat, mix ½ teaspoon of cayenne pepper or red pepper flakes into the creamy sauce. You can also add diced jalapeños for an extra kick.

Low-Carb/Keto Green Bean Casserole

For a low-carb version, skip the cream of mushroom soup and make a homemade sauce using heavy cream, cream cheese, and sautéed mushrooms. Use pork rind crumbs or almond flour-based crispy onions for the topping instead of traditional fried onions.

Each of these variations puts a unique twist on classic Green Bean Casserole, so you can tailor the recipe to fit your taste and dietary needs. Now, let’s go over some expert tips to help you get the best flavor and texture every time.

Expert Tips for the Best Green Bean Casserole

Making a perfect Green Bean Casserole is all about balancing flavors, textures, and consistency. Follow these expert tips to ensure your casserole is creamy, flavorful, and topped with the perfect crispy crunch every time.

1. Avoid a Watery Casserole

One of the biggest challenges is avoiding a watery casserole. Green beans naturally release moisture as they cook, which can lead to a soupy dish if not handled correctly. To prevent this, it’s important to prepare them properly. Fresh green beans should be blanched, drained, and patted dry before baking. Frozen green beans must be thawed and pressed with paper towels, while canned green beans should be thoroughly drained and left in a colander for a few minutes to remove excess liquid.

2. Get the Perfect Creamy Texture

Getting the right creamy texture is another essential factor. The soup-to-milk ratio determines how thick or loose the sauce will be. If you prefer a thicker, richer casserole, reduce the milk to ½ cup instead of ¾ cup. For extra creaminess, a spoonful of sour cream or cream cheese can be mixed into the sauce, adding depth without making the casserole too runny.

3. Make the Crispy Onion Topping Extra Crunchy

The crispy onion topping is what makes Green Bean Casserole truly irresistible, but it can lose its crunch if baked too long. To keep the onions crispy, it’s best to bake the casserole without the onions for the first 25 minutes. Add them only for the last 5–7 minutes of baking. If you want extra crunch, you can even broil the casserole for 1–2 minutes at the end, keeping a close eye to prevent burning.

4. Add More Flavor with Seasonings

Enhancing flavor beyond the classic recipe is another way to elevate this dish. While traditional seasoning includes salt and pepper, adding garlic powder, onion powder, or a splash of Worcestershire sauce can deepen the umami profile. For a gourmet touch, grated Parmesan cheese mixed into the sauce adds a nutty, savory richness.

5. Make It Ahead of Time

Green Bean Casserole is also a fantastic make-ahead dish, which makes it ideal for busy holidays. The casserole can be fully assembled—minus the crispy onions—up to 24 hours in advance and stored in the refrigerator. Before baking, let it sit at room temperature for 15–20 minutes, then bake as usual. This ensures even cooking and prevents cold spots. The crispy onions should always be added at the very end to maintain their crunch.

6. How to Store & Reheat Leftovers

For storing and reheating leftovers, keep the casserole in an airtight container in the refrigerator for up to three days. When reheating, using the oven at 350°F (175°C) for about 15 minutes will restore the creamy texture and help crisp up the onions. The microwave is a quicker option, but it may soften the topping. If freezing, store the casserole without the fried onions for up to two months and add fresh onions when reheating.

By following these simple tips, you’ll ensure your Green Bean Casserole is always creamy, crispy, and packed with flavor. Now, let’s go over the best ways to serve and pair this holiday favorite.

How to Serve & Pair Green Bean Casserole

Green Bean Casserole is a versatile side dish that complements a variety of main courses, making it a staple at holiday feasts, potlucks, and cozy family dinners. Traditionally served at Thanksgiving and Christmas, this creamy, crispy dish pairs beautifully with roasted meats and other comforting sides.

For the best presentation, serve Green Bean Casserole in a ceramic or glass baking dish straight from the oven. The golden, crispy onion topping adds a visually appealing contrast to the creamy green beans beneath. To enhance the serving experience, sprinkle a bit of freshly grated Parmesan or chopped parsley on top just before serving for added flavor and a pop of color.

When it comes to pairings, Green Bean Casserole goes well with a variety of main dishes. It’s a classic match for roasted turkey, making it a Thanksgiving essential, but it also complements glazed ham, roasted chicken, or beef tenderloin just as well. If serving at a casual dinner, it pairs nicely with meatloaf, grilled pork chops, or even a rotisserie chicken for a comforting meal.

Since the casserole itself is rich and creamy, it’s best served alongside dishes that offer a contrast in texture or acidity. Lighter, tangy sides like cranberry sauce, roasted Brussels sprouts with balsamic glaze, or a citrusy salad can balance out the richness. If you’re looking for other creamy side dishes, mashed potatoes or mac and cheese create a decadent, indulgent meal when served together.

For leftovers, Green Bean Casserole can be repurposed in creative ways. Try spooning it over toasted sourdough bread for a creamy, open-faced sandwich, mixing it into scrambled eggs or an omelet, or incorporating it into a hearty pasta bake. If reheating, using the oven instead of the microwave will help maintain the crispy onion topping.

No matter how you serve it, Green Bean Casserole remains a timeless comfort food that’s perfect for holidays and beyond. Now that you know how to pair it with the right dishes, let’s wrap things up with some final takeaways and what to try next.
