I recently tried making this Green Bean and Potato Casserole Recipe, and I have to say, it quickly became a family favorite. There’s something about the creamy texture paired with tender vegetables that feels like comfort on a plate. I love how easy it is to throw together, yet it tastes like it took hours to make.
Every bite brings out that cozy, homemade flavor I crave during dinner. Honestly, it’s the kind of recipe I’ll keep coming back to for holidays or even a simple weeknight meal. You can also enjoy similar hearty flavors in a Chicken Fried Chicken Recipe for a protein-packed dinner.

Ingredients
Here’s everything you’ll need to make this creamy, delicious casserole:
- 1 pound fresh green beans, trimmed and cut into 1-inch pieces – Fresh green beans give the best texture; avoid frozen for a firmer bite.
- 2 pounds potatoes, peeled and diced – Yukon gold potatoes work perfectly for a creamy yet firm consistency.
- 1 medium onion, finely chopped – Adds sweetness and depth to the casserole.
- 1/4 cup butter – Provides richness; I always use unsalted to control saltiness.
- 1/4 cup all-purpose flour – Helps thicken the creamy sauce without lumps.
- 2 cups milk – Whole milk makes the casserole extra creamy.
- 1/2 teaspoon salt – Enhances the natural flavors of the veggies.
- 1/4 teaspoon black pepper – Freshly cracked pepper gives more aroma and flavor.
- 1 cup shredded cheddar cheese – I recommend grating it fresh for the best melt and flavor.
- 1/2 cup breadcrumbs – Adds a lovely crunchy topping; I prefer panko for extra crispiness.

How to Make Green Bean and Potato Casserole Recipe?
Follow these simple steps to make the casserole come together beautifully:
Prepare the Vegetables
First, peel and dice your potatoes into even pieces for consistent cooking. Trim and chop the green beans into 1-inch pieces. Boil potatoes until tender, then drain and set aside.
Make the Creamy Sauce
In a skillet, melt butter over medium heat and whisk in flour to create a smooth roux. Slowly add milk while stirring until the sauce thickens. Season with salt and pepper, then stir in half of the cheddar cheese for extra creaminess.
Combine and Assemble
Mix the cooked potatoes, green beans, and onions with the sauce until evenly coated. Pour into a greased baking dish and spread breadcrumbs on top, then sprinkle the remaining cheese over it.
Bake to Perfection
Place the casserole in a preheated oven at 350°F (175°C) for 25–30 minutes. Bake until the top is golden brown and bubbling, letting it cool slightly before serving.
Additional Tips for Making This Recipe Better
From my experience, these small adjustments really elevate the dish:
- I like to sauté onions slightly before adding them; it enhances sweetness.
- Using fresh cheese instead of pre-shredded makes a noticeable difference in flavor.

- Toast breadcrumbs in butter before topping to get an extra crunch.
