What Ingredients are in Homemade Green Bean Casserole?
Making green bean casserole from scratch means leaving behind the canned soup and gathering fresh, flavorful ingredients that will transform this classic dish. The combination of fresh vegetables, creamy sauce components, and crunchy toppings creates layers of texture and flavor that simply can’t be matched by shortcuts. Ready to upgrade your holiday table? These ingredients will help you create a green bean casserole that guests will remember long after the meal is over.
- 2 pounds fresh green beans, trimmed
- 1 pound mushrooms, sliced
- 2 small red onions, chopped
- 4 ounces (1 stick) butter
- 2 garlic cloves, chopped
- 1 tablespoon fresh thyme leaves
- 1 cup heavy cream
- 1 cup vegetable stock
- Salt and freshly ground black pepper
- 1/4 cup toasted sliced almonds
- 1/2 cup fine dry breadcrumbs
- 1/2 cup vegetable oil
- 1/3 cup all-purpose flour
- 6 white pearl onions, thinly sliced
When shopping for these ingredients, quality matters. Look for bright, firm green beans without blemishes, and mushrooms that aren’t slimy or discolored. Fresh herbs make a noticeable difference in the final flavor, so don’t substitute dried thyme if you can help it. And while pearl onions might seem like a fussy extra step, those homemade crispy onions on top are what transform this from a standard side dish into something truly special. Trust me, once you’ve had freshly fried onions on your casserole, you’ll never go back to the pre-packaged kind.
How to Make this Homemade Green Bean Casserole
Making this homemade green bean casserole is a multi-step process that builds layers of flavor you simply can’t get from the canned soup version.
Start by preparing your vegetables. In a food processor, combine half of your 1 pound of sliced mushrooms and both chopped red onions, processing them until they form a paste. Set this aside—it’s going to be the base of our incredibly rich sauce.
Next, melt the 4 ounces of butter in a large saucepan over medium heat and add the remaining mushrooms. As they begin to release their juices and brown around the edges (which is where all that wonderful flavor comes from), add 2 chopped garlic cloves and 1 tablespoon of fresh thyme leaves.
Now comes the magic. Add that mushroom-onion paste to the saucepan, reduce the heat to medium-low, and cook for about 10 to 15 minutes, stirring occasionally. This slow cooking develops an incredible depth of flavor that will make people wonder what your secret ingredient is.
After the mixture has cooked down, pour in 1 cup of heavy cream and 1 cup of vegetable stock, then season with salt and pepper to taste. Investing in a premium processor set will make preparation much faster and more efficient for this recipe and countless others in your kitchen.
For the green beans, you’ll want to blanch your 2 pounds of trimmed beans in boiling water for just about a minute—we want them bright green and barely tender since they’ll continue cooking in the oven. Immediately plunge them into an ice water bath to stop the cooking process, then drain well.
A premium food processor provides the perfect consistency for the mushroom-onion paste that makes this recipe special.
Combine your blanched green beans with the mushroom mixture, 1/4 cup of toasted sliced almonds, and 1/4 cup of breadcrumbs in a large bowl. Transfer everything to a
Homemade Green Bean Casserole Substitutions and Variations
While the classic green bean casserole recipe is delicious on its own, you’re never locked into following it exactly as written.
I’m all about making recipes work with what you have on hand.
Swap heavy cream for half-and-half or even coconut milk for a dairy-free version.
No fresh mushrooms? Use canned, just drain them well.
Pearl onions not available? French’s crispy onions make a perfect substitute for that crunchy topping.
For flavor variations, try adding bacon bits, substitute chicken stock for vegetable, or mix in water chestnuts for extra crunch.
Cheese lovers might appreciate a handful of sharp cheddar stirred into the sauce.
What to Serve with Homemade Green Bean Casserole
Green bean casserole pairs beautifully with three classic main dishes: roast turkey, glazed ham, or a juicy prime rib.
The creamy mushroom base and crunchy onion topping complement these protein centerpieces perfectly, creating that magical balance we all crave at dinner.
For sides, I recommend mashed potatoes (because can you ever have too many comfort foods?), a tart cranberry sauce, or a simple dinner roll to soak up that delicious sauce.
A crisp green salad with vinaigrette works wonderfully too, cutting through the richness of the casserole with bright, fresh flavors.
