Step-by-Step Cooking Instructions

Making a green bean casserole for a crowd has never been easier! Follow these simple steps to create a delicious holiday recipe that everyone will love. Whether you’re using fresh, frozen, or canned green beans, this casserole for a crowd is a crowd-pleaser casserole perfect for any occasion.

Preparing the Green Beans (Blanching Fresh Beans, Using Canned/Frozen)

To start, you’ll need to prepare your green beans. If you’re using fresh green beans, blanch them first to preserve their vibrant color and crisp texture. To do this:

1. Heat a pot of salted water until it starts to boil.
2. Add your fresh green beans and cook for about 3-4 minutes until they are just tender.
3. After draining, quickly transfer them into an ice bath to prevent further cooking.

For a simple casserole, you can also opt for frozen green beans—just thaw them before use. If you’re in a pinch, canned green beans can be used as well; however, be sure to drain and rinse them to remove excess salt.

Making the Sauce (Homemade or Condensed Soup Options)

The next step is to make the creamy sauce that ties the entire baked casserole together. The classic option uses cream of mushroom soup (the one many know from Campbell’s green bean casserole), but you can also make your own for a more homemade touch.

1. For the classic route, combine a can of cream of mushroom soup with milk to achieve a smooth, pourable sauce. You can use whole milk or a dairy-free alternative like almond milk for those with dietary restrictions.
2. For a homemade sauce, melt 3 tablespoons of butter in a pan, then whisk in 3 tablespoons of flour. Slowly add 2 cups of vegetable or chicken broth, stirring constantly until the sauce thickens. Add sautéed mushrooms for extra flavor and creaminess!

Add a pinch of salt, black pepper, and garlic powder to season your sauce. You can also sprinkle in a bit of McCormick seasoning for added depth.

Assembling & Baking (Layering, Baking Time, Temperature Tips)

Now it’s time to assemble your green bean casserole for 10! Start by layering the blanched or thawed green beans in the bottom of a greased casserole dish. Pour the sauce evenly over the beans, then top with a generous layer of French’s fried onions (or your choice of crispy fried onions) for that irresistible crunch.

1. Preheat your oven to 350°F (175°C).
2. Bake your casserole for 25-30 minutes, or until it’s bubbling and golden brown.
3. During the last 5 minutes of baking, sprinkle a bit more crispy fried onions on top to make sure your casserole has that perfect crunch.

After it’s finished, allow it to cool for a few minutes before serving. This classic side dish is now ready to be part of your next family dinner, festive meal, or easy holiday recipe. Whether it’s for a large family dinner or a comfort food craving, this green bean side dish is always a hit!

This homemade green bean casserole is a perfect balance of creamy and crunchy, making it the ideal holiday recipe for any gathering.

Boosting Flavor & Customizations

While the classic green bean casserole is undeniably delicious, why not take it to the next level with a few tasty tweaks? Whether you want to make it creamier, crispier, or more savory, there are plenty of ways to boost flavor and make your homemade green bean casserole even more irresistible. Here’s how to do it:

Adding Cheese for Extra Richness

Who doesn’t love a little extra cheese in their casserole? Adding cheese to your green bean casserole will take it from great to unforgettable. You can mix in some shredded cheddar, Parmesan, or Gruyère into your creamy sauce for an extra-rich, melty texture. For a more indulgent treat, sprinkle more cheese on top before baking to create a golden, cheesy crust that everyone will love!

• Sharp cheddar gives the casserole a bold, tangy kick.
• Parmesan adds a nutty depth that perfectly complements the green beans.
• Gruyère brings a silky, creamy finish that’s hard to beat.

Adding Mushrooms for an Umami Boost

Want to add some extra savoriness to your dish? Mushrooms are your best friend. Sauté some mushrooms in butter and add them to your sauce, or layer them directly with the green beans for that earthy, umami flavor. They’ll pair perfectly with the creaminess of the sauce and the crispiness of the French’s fried onions. Plus, they’re a great way to amp up the texture of your casserole!

• Button mushrooms or cremini mushrooms work beautifully in this dish.
• If you’re feeling adventurous, try shiitake mushrooms for a deeper, more robust flavor.

Garlic & Spice for Extra Kick

If you’re a fan of bold flavors, don’t shy away from adding a little garlic and spice to your casserole. A couple of cloves of minced garlic sautéed in butter will add that aromatic base to your sauce, giving it an extra layer of flavor. For a spicy twist, sprinkle in some cayenne pepper, or add a dash of smoked paprika for a mild, smoky heat. If you prefer savory over spicy, a dash of onion powder or dried thyme will elevate the flavor without overpowering the dish.

• Garlic adds a rich, savory note that pairs perfectly with the creamy sauce.
• Cayenne pepper or crushed red pepper flakes bring just the right amount of heat.
• Smoked paprika delivers a subtle smokiness that balances the richness of the casserole.

Making It Creamier, Crispier, or More Savory

You’ve got a great base, now let’s make it even better!

• To make it creamier: Add a splash of heavy cream to the sauce, or stir in a couple of dollops of sour cream or cream cheese for a tangy, creamy texture.
• To make it crispier: Double up on the crispy fried onions, or try topping it with panko breadcrumbs for an extra crunchy finish. A sprinkle of Parmesan or a drizzle of melted butter can help those onions crisp up perfectly.
• For a more savory twist: Add a spoonful of soy sauce or Worcestershire sauce to the sauce for an irresistible depth of flavor that will have everyone asking for the recipe.

With these simple additions, you’ll have a green bean casserole that’s rich, savory, and bursting with flavor. It’s the perfect comfort food that’s guaranteed to be a hit at your next gathering, whether it’s a holiday recipe, a family dinner, or a festive meal with friends. There’s no limit to what you can do—let your creativity run wild!

Recipe Tips & Make-Ahead Instructions

Hosting a big meal should be about enjoying the company, not stressing over last-minute cooking. With this green bean casserole for 10, you can easily prep ahead of time for a stress-free hosting experience. Plus, when it’s time for leftovers, we’ve got the best tips for storing and reheating so you can savor the comfort food goodness all over again.

How to Prepare in Advance for Stress-Free Hosting

Preparing your green bean casserole for 10 ahead of time not only saves you time, but it also makes your gathering much more enjoyable. Here’s how to make it ahead:

1. Assemble the casserole: Prepare the entire dish, including the sauce, green beans, and crispy onion topping, but don’t bake it just yet. Cover the dish tightly with plastic wrap or foil and store it in the fridge for up to 2 days. This makes it perfect for those busy days leading up to your holiday recipe or family dinner.
2. Bake when ready: On the day of your gathering, just pop it in the oven at 350°F (175°C) for 25-30 minutes, or until it’s hot and bubbling. If you’ve kept it in the fridge overnight, you may need to add an extra 10-15 minutes to the baking time.
3. Make the sauce in advance: If you’re short on time, you can even make the creamy sauce a day ahead. Just store it in an airtight container in the fridge and combine it with the green beans and crispy onions right before baking.

Best Way to Store, Reheat, and Serve Leftovers

Even if your casserole disappears in no time, there will still be leftovers—trust us! Here’s how to store, reheat, and enjoy them the next day:

Storing leftovers: After your comfort food feast, let the casserole cool completely before storing it. Cover it tightly with plastic wrap or foil and refrigerate for up to 4 days.

Reheating: To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes until hot. If you want to keep the crispy topping intact, cover the dish with foil for the first 10 minutes and uncover it for the last 10 minutes.

Freezing for later: If you have a lot of leftovers or want to prep ahead for another meal, you can freeze the casserole. Let it cool completely, cover it with foil, and store it in a freezer-safe container for up to 2 months. When you’re ready to serve, thaw it in the fridge overnight, then bake at 350°F (175°C) for 30-40 minutes.

This simple casserole for a crowd is perfect for making ahead, storing, and reheating without losing any of that delicious flavor. Whether you’re preparing for a festive meal, a holiday recipe, or a cozy family dinner, these tips will help you serve up your green bean side dish with ease and minimal fuss!
