Here’s what goes into this Homemade Green Bean Casserole—no surprises, just simple ingredients you probably already have.

Fresh green beans – 1 ½ pounds, trimmed and halved
No worries if you don’t have fresh; you can use frozen green beans too. Just thaw and drain well before using.

Butter – 3 tablespoons
I like adding a bit more to get that rich, creamy base. You’ll find butter in the dairy aisle, easy to grab.

All-purpose flour – 3 tablespoons
This helps create the creamy sauce from scratch. No special flour needed.

Milk – 2 cups (whole or 2%)
You can swap for unsweetened almond milk for a lighter touch if you want a healthy green bean casserole.

Salt and black pepper – to taste
Simple seasoning that pulls everything together.

Garlic powder – ½ teaspoon
Optional but gives a nice extra layer of flavor.

Onion powder – ½ teaspoon
Another layer of flavor that complements the green beans.

Crispy fried onions – 1 ½ cups
This is the star topping and what makes the classic green bean casserole so beloved. If you don’t have these, you can make your own or find them in the snack aisle. They add that perfect crunch.

Mushrooms – 1 cup, sliced
For an earthy flavor that feels extra special but still everyday.

This Homemade Green Bean Casserole keeps costs reasonable because it uses pantry staples and fresh vegetables. No need for fancy things or specialty items that can get pricey.

Prep tip: To make things easier, trim your green beans ahead and even blanch them if you have the time—it speeds up cooking later. Leftover casserole can be stored in an airtight container in the fridge for 3 to 4 days, making it a great make-ahead dish for busy weeks.

1. Preheat your oven to 350°F. While that heats up, get your ingredients ready.

2. Cook the green beans. Bring a large pot of salted water to a boil. Add the green beans and cook for about 5 minutes until tender but still bright green. Drain and set aside. This step ensures your Homemade Green Bean Casserole isn’t soggy later.

3. Make the creamy sauce base. In a large skillet over medium heat, melt the butter. Once melted, whisk in the flour. Stir constantly for 2 minutes, cooking off the raw flavor. This is where I used to rush my Homemade Green Bean Casserole, but taking your time really pays off to avoid lumps.

4. Slowly whisk in the milk. Keep stirring until the sauce thickens, about 4 to 5 minutes. It should coat the back of a spoon. Season with salt, pepper, garlic powder, and onion powder. Your kitchen will smell amazing right about now.

5. Add mushrooms. Stir in the sliced mushrooms and cook for 3 more minutes until softened.

6. Combine green beans and sauce. Add the cooked green beans to the skillet and gently mix to coat everything evenly.

7. Transfer mixture to a baking dish. Use an 8×8 or similar baking dish.

8. Top with crispy fried onions. Spread the onions evenly over the top. This crispy fried onions green bean casserole touch makes all the difference.

9. Bake uncovered for 25 minutes. Your Homemade Green Bean Casserole will bubble around the edges and the onions will turn golden.

10. Let rest for 5 minutes. This helps everything set so it’s easier to serve.

From start to finish, this Homemade Green Bean Casserole takes about 45 minutes, but the hands-on time is really closer to 20. While that cooks, you can set the table or make a simple salad.

If you love classic green bean casserole recipes but want that fresh-from-scratch flavor and texture without complicated steps, this one checks all the boxes. Don’t worry if your Homemade Green Bean Casserole doesn’t look exactly picture-perfect—it’s the taste that counts, and this certainly delivers!

This Homemade Green Bean Casserole pairs wonderfully with mains like roasted chicken, turkey, or even a simple pork roast. Its creamy texture and crispy topping balance beautifully with protein-focused dishes.

My favorite way to serve this Homemade Green Bean Casserole is for a cozy dinner or when we have guests. It’s also a perfect side for holidays because it feels familiar and comforting, but making it from scratch gives it a fresh twist everyone appreciates.

For sides, try easy mashed potatoes or a crisp green salad with vinaigrette to cut through the richness. Roasted carrots or sweet potatoes add some seasonal color and sweetness, making the meal feel complete without overcomplicating things.

Presentation tip: Serve in a pretty casserole dish right from the oven. The golden crispy fried onions on top always catch the eye and invite everyone to dig in.

Got leftovers? They’re great warmed up the next day. You can also mix them into a frittata for a tasty breakfast or serve alongside eggs for a unique twist.

Seasonal variations I’ve tried include adding a bit of fresh thyme or rosemary to the sauce for a subtle herb note or mixing in some slivered almonds for extra texture. Friends and family always enjoy how this dish feels familiar yet slightly elevated—a true crowd-pleaser every time.

Can I make this Homemade Green Bean Casserole ahead of time?
Absolutely. I often prepare it the day before and refrigerate it without the fried onions on top. Add the crispy fried onions just before baking to keep them crunchy.

What’s a good substitute for crispy fried onions?
If you don’t have crispy fried onions handy, crushed fried shallots work well or make your own by frying thinly sliced onions until golden. For a healthy green bean casserole, toasted breadcrumbs can be a crunchy alternative.

How do I adjust this Homemade Green Bean Casserole for more or fewer people?
For bigger groups, I double the recipe and use a larger baking dish. For smaller servings, halve each ingredient. Cooking time might adjust slightly, so watch for bubbling and golden topping.

Can I use canned green beans for this?
You can, but fresh or frozen yield better texture and flavor. If you do use canned, drain well and reduce cooking time as they’re already cooked.

Is this a healthy green bean casserole?
Compared to the canned-soup versions, yes! This Homemade Green Bean Casserole uses fresh ingredients and makes a creamy sauce from scratch, avoiding preservatives and excess sodium.

Can I freeze leftovers?
I don’t recommend freezing the full casserole because the fried onions lose their crispness. You can freeze the green bean and sauce mixture separately and add fresh toppings when thawed.

How can I make this dish dairy-free?
Swap the butter for a dairy-free spread and use unsweetened almond or oat milk for the sauce. Make sure your crispy fried onions don’t contain dairy.
