Ingredients You’ll Need
This Green Bean Casserole with French-Fried Onions and Cheddar Recipe is made with simple, everyday ingredients that come together to create something truly special. Each component plays a crucial role, whether it’s adding richness, tang, or that perfect crispy finish.
- Green beans (1 lb fresh or frozen): The star vegetable, providing a fresh, crisp bite and vibrant green color.
- Condensed cream of mushroom soup (10.5 oz can): Creates the creamy base that holds the casserole together and infuses it with savory mushroom flavor.
- Milk (1/2 cup): Lightens the soup slightly and helps achieve a smooth texture.
- Soy sauce (1 teaspoon): Adds a subtle umami depth that enhances the overall savoriness.
- Ground black pepper (1/4 teaspoon): Brings just enough spice for balance without overpowering.
- French-fried onions (1 1/3 cups, divided): The crispy topping everyone loves, with enough inside the casserole for texture and on top for that golden crunch.
- Cheddar cheese (optional, 1/4 cup grated): Adds a sharp, creamy cheese flavor that makes this casserole stand out.
How to Make Green Bean Casserole with French-Fried Onions and Cheddar Recipe
Step 1: Preheat the Oven
Start by setting your oven to 350°F (175°C). Preheating ensures that your casserole bakes evenly and the ingredients meld together perfectly.
Step 2: Cook the Green Beans
If you are using fresh green beans, blanch them in boiling water for 4 to 5 minutes until just tender but still vibrant and crisp. If you’re using frozen, simply thaw and drain them well to avoid any excess water diluting your creamy sauce. This step keeps the green beans from getting mushy during baking.
Step 3: Mix the Casserole
In a large bowl, combine the cream of mushroom soup, milk, soy sauce, and ground black pepper. Stir in 2/3 cup of French-fried onions, then fold in the cooked green beans and, if you love that cheesy punch, add the grated cheddar cheese. This mixture is the heart of the dish — creamy, flavorful, and packed with texture.
Step 4: Assemble the Casserole
Pour the mixture into a 9×9-inch baking dish, spreading it evenly. This size helps the casserole cook through properly while giving enough surface area for that topping to bake beautifully.
Step 5: Bake and Add Fried Onions
Bake the casserole for about 25 minutes until it’s hot and bubbling around the edges. Then sprinkle the remaining French-fried onions over the top and return to the oven for another 5 to 10 minutes. This final baking step crisps up the onions to a gorgeous golden brown that provides a delightful crunch with every bite.
Step 6: Serve
Remove the casserole from the oven and let it cool for a few minutes. This brief resting time allows the dish to set slightly, making it easier to serve and even more enjoyable to eat.
How to Serve Green Bean Casserole with French-Fried Onions and Cheddar Recipe

Garnishes
To elevate the visual appeal and add a fresh burst of flavor, garnish your casserole with a sprinkle of chopped fresh parsley or chives. These bright greens complement the creamy casserole and add a hint of herbal freshness to each bite.
Side Dishes
This Green Bean Casserole with French-Fried Onions and Cheddar Recipe pairs wonderfully with classic comfort foods like mashed potatoes, roasted turkey, or a simple baked ham. Light green salads or crusty bread can help balance the richness for a well-rounded meal.
Creative Ways to Present
For a fun twist at holiday gatherings or dinner parties, serve the casserole in individual ramekins or mini cast-iron skillets. You can also mix in some toasted almonds or crispy bacon bits for extra texture and flair, making the dish uniquely yours.
Make Ahead and Storage
Storing Leftovers
Leftover green bean casserole stores beautifully in an airtight container in the refrigerator for up to 3 days. Cover it well to keep the onions from getting soggy, and you’ll have a delicious second round ready to enjoy.
Freezing
You can freeze this casserole either before baking or after it has been cooked and cooled. If freezing beforehand, prepare the casserole but hold off on adding the crispy onions on top; add them fresh after thawing just before baking. When fully cooked, wrap tightly and freeze for up to 2 months.
Reheating
Reheat leftovers in the oven at 325°F until warmed through and the topping is crisp again. If reheating from frozen, thaw overnight in the fridge and re-crisp the onions separately if needed to maintain that signature crunch.
FAQs
Can I use fresh green beans instead of frozen?
Absolutely! Fresh green beans add a lovelysnap and brightness to the casserole. Just be sure to blanch them briefly to keep their texture perfect during baking.
Is the cheddar cheese necessary?
The cheddar cheese adds a wonderful depth of flavor but is optional. If you prefer a more traditional casserole, you can easily skip it or substitute with your favorite cheese.
Why do I need to add soy sauce?
The soy sauce contributes a subtle umami boost that enhances the mushroom flavor and overall savoriness without making the dish taste Asian. It’s a little secret weapon for balancing flavors.
How can I make this casserole gluten-free?
Use gluten-free cream of mushroom soup and gluten-free French-fried onions. There are several brands that cater to gluten-free needs and this substitution keeps the dish just as tasty.
Can I prepare this casserole ahead of time?
Yes! It can be assembled a day in advance and kept covered in the fridge. Just add the final French-fried onion topping right before baking to ensure maximum crispiness.
