Ingredients for campbell's green bean casserole recipe with cheese
Pantry staples and a few fresh touches bring back 1950s comfort in one dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 2 lbs | Trimmed, cut into 2-inch pieces |
| Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, Campbell's preferred |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium or sharp cheddar |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Crispy Fried Onions 🧅 | 1 cup | Store-bought or homemade |
| Garlic Powder 🧄 | ½ tsp | For extra flavor |
| Onion Powder 🧅 | ½ tsp | For depth of flavor |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish |
The Campbell's cream of mushroom soup is the backbone here—stick with the classic canned version for that authentic taste. I always grab the 10.5 oz cans at Walmart or Kroger since they're reliable and affordable. For the green beans, fresh is best—they stay crunchier than canned. Trim the ends and cut them into even 2-inch pieces so they cook uniformly. The fried onions? Store-bought works fine—just check the label for no artificial colors if you're picky. I like the Heinz brand for that classic crunch.
No Campbell's soup? Homemade mushroom cream sauce works too—sauté mushrooms, add cream and flour, then reduce. Short on milk? Half-and-half or heavy cream gives extra richness. The cheese can be swapped for Monterey Jack or Swiss if cheddar isn't available. For a veggie twist, add diced carrots or corn to the green beans. The parsley is just for garnish, so skip it if you're out—no one will notice. Need extra crispiness? Toast breadcrumbs with butter as a fried onion substitute.
This casserole reheats beautifully—5 minutes at 350°F restores that creamy texture. Keeps 4-5 days in the fridge, freezes for 3 months. Double the recipe for holidays—it's always a crowd-pleaser. I like to make it ahead and let the flavors meld overnight. The more it sits, the better it tastes.

Step-by-step instructions for Campbell's green bean casserole with cheese
This classic dish brings nostalgic comfort to your table with minimal effort.
Blanch and Prep the Green Beans
Trim the ends from the 2 lbs of fresh green beans and cut them into 2-inch pieces. Place them in a large pot of boiling salted water and cook for 5-7 minutes until they're bright green and tender-crisp. You'll know they're done when they hold their shape but can still be easily pierced with a fork.
Drain the beans immediately and rinse them under cold water to stop the cooking process. Spread them on a clean kitchen towel and pat dry thoroughly. This step is crucial for preventing a soggy casserole later—moisture is the enemy of crispy fried onions on top.
Make the Creamy Mushroom Sauce
In a large mixing bowl, combine the 2 cans of cream of mushroom soup, 1 cup of milk, 0.5 cup of melted butter, 2 tbsp of all-purpose flour, 0.5 tsp of garlic powder, 0.5 tsp of onion powder, 1 tsp of salt, and 0.5 tsp of black pepper. Whisk everything together until the mixture is completely smooth and free of lumps.
Here's the thing—this sauce is the heart of your casserole, so take your time blending it well. The flour will help thicken the sauce as it bakes, creating that perfect creamy consistency. If you notice any lumps, strain the mixture through a fine-mesh sieve for an ultra-smooth texture.
Combine Beans and Sauce
Add the drained green beans to the sauce mixture and stir gently to coat each piece evenly. The beans should be fully immersed in the creamy sauce, but don't worry if they're not perfectly covered—they'll absorb some of the sauce as they bake.
Transfer the bean mixture to a greased 9x13-inch baking dish. Spread it out evenly, making sure to cover the entire bottom of the dish. This even distribution helps the casserole cook uniformly and prevents any dry spots. Don't pack it down—just let it settle naturally in the dish.
Bake and Top with Cheese
Preheat your oven to 350°F and bake the casserole uncovered for 30 minutes. This initial baking time allows the flavors to meld and the sauce to begin thickening. After 30 minutes, sprinkle the 2 cups of shredded cheddar cheese evenly over the top of the casserole.
Return the dish to the oven and bake for another 15-20 minutes until the cheese is fully melted and golden brown. The edges should be bubbling slightly, and the top should have a beautiful, creamy cheese crust. If you're worried about the cheese browning too quickly, tent the dish loosely with aluminum foil during the last 5 minutes of baking.
Add Crispy Toppings and Garnish
Remove the casserole from the oven and immediately sprinkle the 1 cup of crispy fried onions evenly over the melted cheese. The onions should be distributed in a single layer, covering the entire surface. Let the casserole rest for 5 minutes to allow the onions to crisp up slightly from the residual heat.
Finally, garnish with the 2 tbsp of chopped fresh parsley. This adds a pop of color and a fresh contrast to the rich, cheesy topping. Serve warm, straight from the oven, with a side of crusty bread to soak up every last bit of that creamy goodness. The combination of crispy onions, melted cheese, and tender green beans makes this dish pure comfort in every bite.
Pro Tips For Making Campbell'S Green Bean Casserole Recipe With Cheese
- Blanch Beans First: Skip the mushy texture by blanching green beans for 3-4 minutes in boiling salted water, then shocking them in ice water. This keeps them crisp-tender and prevents the soup mixture from turning them into a sad, limp pile—trust me, I’ve served both versions at Thanksgiving.
- Stir in Butter Last: Mix the cream of mushroom soup and milk first, then fold in butter off the heat. Adding it earlier can make the sauce split or turn greasy, and nobody wants a casserole that looks like a science experiment gone wrong.
- Don’t Overmix the Cheese: Sprinkle the shredded cheddar evenly on top—don’t stir it into the soup. Uneven distribution leads to clumpy, rubbery spots, and we’re aiming for that classic golden, bubbly blanket, not a cheese minefield.
- Bake Until Bubbly: Cover the casserole with foil for the first 20 minutes to trap steam, then uncover and bake until the cheese is deep golden and the edges are slightly browned. Rushing this step = sad, pale cheese. Patience here makes the difference.
Storing and reheating this recipe
Refrigerator Storage
Let your casserole cool completely before transferring to an airtight container—I use glass Pyrex with a tight-sealing lid—to maintain freshness. Store in the fridge at 40°F or below for up to 4-5 days.
The flavors actually deepen overnight, so I often make it ahead for Sunday dinners. Just give it a stir before reheating to redistribute the creamy sauce. 💫
Freezer Prep Tips
For long-term storage, freeze the casserole in a single layer in a 9x13-inch freezer-safe dish or divide into quart-sized freezer bags. Leave 1-inch headspace for expansion and label with the date. It keeps for 3 months without texture loss.
Thaw overnight in the fridge before reheating for best results. I always double-wrap the dish in plastic wrap before adding the lid to prevent freezer burn. ❄️
Oven Reheating
Preheat your oven to 350°F and place the casserole in a baking dish. Cover it tightly with aluminum foil and bake for 25-30 minutes until heated through. The cheese should melt smoothly, and the onions will regain their crispiness.
For extra creaminess, add 2 tbsp milk or cream before reheating. Stir gently to redistribute the sauce evenly. 🔥
Microwave Method
For quick reheating, transfer individual portions to a microwave-safe dish and cover loosely with a damp paper towel. Heat on medium power (50%) for 3-4 minutes, stirring halfway. If the cheese looks dry, add a splash of milk to restore creaminess.
Avoid high power—it can make the onions soggy. I find this works best for single servings when I'm in a hurry. ⏱️
Stovetop Revival
Place the casserole in a skillet over low heat and cover with a lid. Add ¼ cup milk or broth to prevent sticking and heat gently for 10-15 minutes, stirring occasionally.
This method is great for restoring that restaurant-quality texture while keeping the onions crisp. I use this when I want to reheat the entire dish for a family gathering. 🍴
Crispy Topping Rescue
If your fried onions lose their crunch after reheating, sprinkle fresh ones on top right before serving. For extra crispiness, toast breadcrumbs with butter in a dry pan for 2-3 minutes and sprinkle them over the reheated casserole.
This little trick brings back that classic crunch without extra effort. Trust me, your guests won't notice the difference! 🧅

Frequently asked questions
Can I use canned green beans instead of fresh?
Yes, but the texture will be different. Drain and rinse canned beans well, then pat them completely dry before mixing with the sauce. For extra flavor, add ½ tsp garlic powder and ½ tsp onion powder directly to the beans. The casserole will still be delicious, though the beans won't have that fresh-crunch factor.
What if I don't have Campbell's cream of mushroom soup?
No problem! Make a quick substitute by sautéing 2 cups chopped mushrooms in 2 tbsp butter, then adding 1 cup milk and 2 tbsp flour to thicken. Season with 1 tsp salt, ½ tsp black pepper, and ½ tsp garlic powder. Simmer until smooth—it'll taste just as rich!
How do I make this dish ahead of time?
Assemble the casserole completely, then refrigerate it uncovered for 2-3 hours before baking. This helps the flavors meld beautifully. For make-ahead dinners, bake it 1 day ahead, cool completely, then store in an airtight container. Reheat covered with foil at 350°F for 20-25 minutes—the cheese will melt perfectly.
Can I make this vegetarian or vegan?
Swap the cheese for vegan cheddar shreds and use vegan cream of mushroom soup (like Imagine brand). For extra creaminess, add ¼ cup coconut milk to the sauce. The green beans and fried onions stay the same—just ensure your onions are vegan-friendly too!
Why did my casserole turn out watery?
This usually happens if the green beans weren't drained or patted dry enough. Next time, spread them on a towel and press gently to remove all moisture before mixing with the sauce. Also, make sure your baking dish isn't too large—use a 9x13-inch pan for the best texture. If it's still too wet, bake uncovered for 5-10 extra minutes to evaporate excess liquid.
