How to Make Green Bean Casserole Recipe
Step 1: Prep Your Baking Dish
Start by preheating your oven to 350°F to set the stage for bubbly, golden perfection. Grab a 9×9-inch baking dish and lightly grease it with cooking spray or butter—this keeps each scoop corners-to-center as delightful as the last.
Step 2: Mix Up the Sauce
In a large bowl, whisk together the cream of mushroom soup, milk, soy sauce, and black pepper. Take your time here—this luscious sauce is what will coat every green bean, bathing them in savory goodness once baked.
Step 3: Add Green Beans and Onions
Fold in your cooked green beans and 2/3 cup of the crispy fried onions. Stir until the beans are evenly coated and every piece looks thickly covered—this ensures the flavors meld and the onions’ savoriness is infused throughout.
Step 4: Assemble and Bake
Pour the mixture into your prepared dish, spreading it into an even layer. Slide it into the oven and bake for 25 minutes, letting the casserole bubble and set until heated through and just starting to brown around the edges.
Step 5: Top and Crisp
Carefully take out the dish and generously scatter the remaining fried onions all over the top. Pop it back in for about 5 minutes, just until those onions are gorgeously golden and extra crunchy.
Step 6: Serve and Savor
Let your Green Bean Casserole Recipe cool for a few minutes, then serve it warm while the onions are still at peak crispiness. Every forkful should be creamy, crunchy, and downright irresistible!
How to Serve Green Bean Casserole Recipe

Garnishes
For a special touch, sprinkle a little chopped fresh parsley or chives on top just before serving. This not only adds a cheerful pop of color but brings herby freshness to balance the richness of the casserole.
Side Dishes
The Green Bean Casserole Recipe shines next to classic main dishes like roast turkey, baked ham, or juicy chicken. It’s also lovely with mashed potatoes, sweet potato casserole, or warm dinner rolls for a full comfort feast!
Creative Ways to Present
If you love entertaining, try baking individual portions in ramekins for personal-sized servings. You could also build it in a cast-iron skillet for rustic flair, or top with extra onions and parmesan for a cheesy twist at the table.
Make Ahead and Storage
Storing Leftovers
To keep your Green Bean Casserole Recipe tasting fresh, cover leftovers tightly and store them in the refrigerator for up to 3 days. The flavors only get better, making leftover night just as exciting!
Freezing
You can freeze the baked casserole for up to 2 months. For best results, cool completely, wrap tightly in foil, and stash in a freezer-safe container. Reserve the fried onion topping to sprinkle on just before reheating for maximum crunch.
Reheating
For that fresh-baked feel, reheat the casserole (uncovered) in a 350°F oven until warmed through and onions are crisped again, about 15-20 minutes. A microwave works too, though the oven keeps those onions extra tasty.
FAQs
Can I use fresh or frozen green beans instead of canned?
Absolutely! Just cook fresh or frozen beans until tender, then proceed as instructed. They add extra color and a satisfying snap to the casserole.
Is there a dairy-free version of this recipe?
You can make this Green Bean Casserole Recipe dairy free by using a plant-based cream of mushroom soup and non-dairy milk. There are also crispy fried onions made with no animal products that work wonderfully.
How do I keep the fried onions crisp?
The key is to add the final layer of onions for the last five minutes of baking. This way, they stay crunchy and don’t get soggy from baking too long.
Can I make it ahead?
Definitely! You can assemble the casserole (without the final onion topping), cover, and refrigerate up to a day in advance. Add the last of the onions and bake just before serving.
What if I want extra flavor?
Try a sprinkling of garlic powder or substitute some of the soup with sautéed fresh mushrooms. A handful of shredded cheddar on top before the final bake adds cheesy flair, too!
