Step-by-step preparation for Creamy Green Bean Casserole from Scratch
Creating a creamy green bean casserole from scratch is a delightful way to bring a bit of home-cooked comfort to your kitchen. Follow these simple steps, and you'll have a delicious dish ready to impress your guests or satisfy your family.
Preheat and Prepare Your Baking Sheet
Start by preheating your oven to 450°F (232°C). This step is crucial as it allows your baked onions to crisp perfectly. While the oven heats up, line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking. This small detail will lead to easier cleanup later on.
Make the Baked “Fried” Onions
These baked onions elevate your casserole! Slice one medium onion thinly and separate the slices. Here’s a little tip: set up three bowls—one with ½ cup of all-purpose flour, the second with ¾ cup of panko breadcrumbs mixed with ½ teaspoon of salt and ¼ teaspoon of ground black pepper, and the third with a whisked mixture of 1 large egg and 1 tablespoon of milk.
Using one hand for dry ingredients and the other for wet makes this process smoother. First, dip the onion slices in the flour, then coat them in the egg mixture, and finally give them a hearty dunk in the panko. Spread them out on your prepared baking sheet and pop them in the oven for about 20 minutes, flipping occasionally until they are golden brown and crispy. While they bake, you can move on to the next steps.
Blanch the Green Beans
Grab a large saucepan and boil a gallon of water with 1 tablespoon of salt. Once it's bubbling, throw in your trimmed and halved 1 pound of fresh green beans. Blanch them for 5 minutes, then quickly transfer them into a bowl of ice water to stop the cooking process. This helps keep the beans vibrant and crunchy. After they’ve cooled, drain and set aside.
Prepare the Mushroom Sauce
In a large ovenproof skillet, melt 2 tablespoons of unsalted butter over medium-high heat. Add 8 ounces of sliced mushrooms, season with 1 teaspoon salt and ½ teaspoon black pepper, and cook until they start to release moisture—about 5 minutes. Stir in 2 cloves of minced garlic, cooking for another 2 minutes before adding 2 tablespoons of flour. This will form the basis of your creamy sauce. Next, pour in ¾ cup of chicken or vegetable broth, allowing it to simmer for 3 minutes. Slowly add 1 and ¼ cups of half-and-half, simmering until everything thickens nicely—around 10 minutes should do the trick.
Combine Ingredients and Bake the Casserole
Now it’s time to unite all those delicious elements! Mix the blanched green beans into the mushroom sauce, along with about a quarter of your crispy onions. If you’re using a stovetop skillet, this is where you'll transfer everything into a greased 2–3 quart casserole dish. Top with the remaining onions and bake at 400°F (204°C) until the casserole is bubbling and the onions are even crispier, roughly 15 minutes.
And there you have it—a creamy green bean casserole from scratch that’s sure to be a hit! Serve warm, and watch it disappear in no time. Enjoy those leftovers too; they keep beautifully in the fridge for up to 4 days!

Variations on Creamy Green Bean Casserole
Substitute Mushrooms with Bell Peppers
If you're looking to switch things up in your creamy green bean casserole from scratch, consider substituting mushrooms with vibrant bell peppers. This not only adds a pop of color but also a sweet, crunchy texture that complements the creamy sauce beautifully. Simply sauté sliced bell peppers alongside your garlic for a fresh twist that's perfect for those who aren’t fans of mushrooms.
Add a Cheese Layer for Extra Creaminess
For an ultra-indulgent experience, layer in some cheese! Whether you opt for sharp cheddar or creamy Gruyère, sprinkle a handful between the green beans and sauce before topping it with baked onions. The melted cheese will add a luxurious creaminess that transforms your green bean casserole into the ultimate comfort dish—perfect for cozy gatherings or family dinners.
These variations not only enhance the flavor but also keep things exciting. What’s your favorite twist on this classic dish?
