What You’ll Need:
This Homemade Green Bean Casserole keeps the ingredient list totally approachable—because good food shouldn’t be complicated.
- 1½ pounds fresh green beans, trimmed and cut into 2-inch pieces (or use frozen if you’re in a pinch!)
- 3 tablespoons unsalted butter
- 8 ounces fresh mushrooms, sliced (white button or cremini both work wonderfully)
- 3 cloves garlic, minced (for that flavorful punch)
- 3 tablespoons all-purpose flour
- 1 cup whole milk (a creamy base for the mushroom sauce)
- 1 cup chicken or vegetable broth (grab it from any regular grocery store)
- 1 teaspoon soy sauce (adds subtle depth)
- Salt and black pepper to taste
- 1½ cups crispy fried onions (the golden crunchy crown of this dish! You can find these near the salad bars or in the canned veggies aisle)
- Optional: ½ cup shredded cheddar cheese (my secret little upgrade—it adds a savory twist)
Out of green beans? No problem! You can swap in fresh asparagus or even green peas for a seasonal spin on this easy green bean casserole. Looking for a dairy-free version? Use your favorite plant-based milk and broth substitutes—it’s just as good!
One kitchen nugget: trim and prep your green beans in advance. They store great in a sealed container for a day or two, saving you time on cooking day. And leftovers? Store them in an airtight container in the fridge for up to 3 days. These leftovers taste fantastic reheated—sometimes even better as the flavors meld.
Let’s Cook This Together:
Start to finish, this Homemade Green Bean Casserole comes together in about 45 minutes, and it’s the kind of dish you can make with a little multitasking.
- Prep your green beans: Bring a large pot of salted water to a boil. Add the green beans and cook for 5 minutes until crisp-tender. Drain and immediately plunge them into ice water to stop cooking. This keeps them bright green and perfect.
- Make the mushroom sauce: While the beans blanch, melt butter in a large skillet over medium heat. Toss in the sliced mushrooms and sauté until softened and fragrant—about 5 minutes.
- Add garlic and flour: Stir in the minced garlic and cook for a minute. Sprinkle the flour over the mushrooms and stir to coat everything, cooking for another 1-2 minutes. This is your thickening magic for the cream sauce.
- Pour in milk and broth: Slowly whisk in the milk and broth, stirring constantly. Add soy sauce and season with salt and pepper. Keep stirring until the sauce thickens and is rich and creamy.
- Combine beans and sauce: Drain your green beans and mix them into the mushroom sauce. Give everything a gentle toss to coat evenly.
- Transfer to baking dish: Pour this green bean goodness into a greased 9×13-inch casserole dish.
- Add crispy topping: Sprinkle the crispy fried onions over the top—this is the crunch promise that makes this easy green bean casserole sing.
- Bake: Pop it in a preheated 350°F oven for about 20-25 minutes, until bubbly and golden.
If your Homemade Green Bean Casserole looks a bit pale when it comes out, don’t worry! The onion topping will provide all the color and crunch this dish needs. Oh, and while it bakes, pour yourself a favorite drink—you’ve earned that. This recipe is so forgiving, so if you want to make ahead, see the FAQs below!
How to Serve & Savor It:
This Homemade Green Bean Casserole truly shines when you serve it with classic holiday mains like roast turkey or ham, or simply alongside grilled chicken and mashed potatoes for a weeknight feast. The creamy texture and crispy fried onions bring a balance that pairs beautifully with protein-based dishes and creamy salads.
For presentation, I love serving it in the same casserole dish you baked it in—there’s something so cozy and inviting about that rustic vibe. Sprinkle a few extra crispy onions or fresh herbs like parsley on top for a pop of color.
Leftovers? I have to tell you—the next day, this casserole makes a killer breakfast hash. Just heat it up, crack an egg or two on top, and sprinkle with cheese for a hearty start to your morning. Seasonal twist alert: in springtime, adding fresh peas instead of green beans makes this dish feel lighter and brightens up the plate.

Your Questions, Answered:
Can I prep parts of this Homemade Green Bean Casserole ahead?
Absolutely! You can blanch the green beans and make the mushroom sauce a day in advance. Store separately, then assemble and bake when you’re ready. This makes for an effortless dinner day.
What if I don’t have fresh mushrooms?
No worries! You can use canned mushrooms for convenience, but fresh will always give a better flavor. For a shortcut, grab a cream of mushroom sauce from your pantry, but skip the canned soup option if you want a fresher, more vibrant casserole.
Can I make this Homemade Green Bean Casserole vegan or dairy-free?
Totally! Use plant-based butter and milk, plus vegetable broth. Swap crispy fried onions for a homemade crunchy topping using panko breadcrumbs toasted with olive oil.
How can I make this for a smaller or bigger crowd?
Simple scaling here! This recipe works with plenty of flexibility. Just keep your ratio of green beans to sauce roughly the same and adjust onion topping accordingly.
What’s the best way to keep crispy fried onions crunchy?
Add the onions right before baking or sprinkle some freshly before serving for max crunch. If your casserole sits for a bit, the topping can get soft—no big deal, but fresh onions are definitely the MVP of crispiness.
Any fun variations I should try?
Try mixing in cooked bacon bits or swapping cheddar cheese for Parmesan in the sauce. For a spicy kick, a dash of smoked paprika or cayenne adds a nice layer without overpowering.
