This dish combines the simplicity of canned ingredients with the indulgence of homemade comfort food. Whether you’re preparing a festive spread or just looking to elevate your weeknight dinner, this cheesy take on a timeless favorite will make everyone reach for seconds.

Let’s dive into how to make this dish, explore the role of each ingredient, and learn some tips to make it perfect every time.

Ingredients

For the Casserole Base

• 4 cans (14.5 oz each) French cut green beans, drained
• 1 can (10.5 oz) cream of mushroom soup
• 1 can (10.5 oz) cream of celery soup
• 1 cup sharp cheddar cheese, shredded
• 1/4 tsp kosher salt
• 3 oz French fried onions

For the Topping

• 1 cup sharp cheddar cheese, shredded
• 3 oz French fried onions

Ingredient Breakdown

Each component plays an essential role in creating the casserole’s rich flavor and signature texture.

French Cut Green Beans

Using French cut green beans (thinly sliced lengthwise) ensures a soft, velvety texture that blends perfectly with the creamy sauce. The beans hold their shape well without feeling heavy, and their mild sweetness balances the richness of the cheese and soups. Canned beans are the classic choice here for convenience and consistency, but you can substitute frozen or fresh beans if preferred.

Cream of Mushroom Soup

This soup brings a deep, earthy flavor that forms the backbone of the casserole’s creaminess. The mushrooms add subtle umami depth that balances the saltiness of the cheese and onions. For a lighter option, you can use a reduced-sodium or low-fat variety without sacrificing taste.

Cream of Celery Soup

This underrated ingredient adds a fresh, aromatic layer to the flavor profile. The celery undertones complement the green beans beautifully, cutting through the richness and keeping the dish balanced. Together, the two soups create the luscious base that defines the casserole’s texture.

Sharp Cheddar Cheese

Cheese is the key to this recipe’s “cheesy” charm. Sharp cheddar adds both creaminess and tang, with a rich flavor that melts perfectly into the sauce. It gives the casserole that crave-worthy gooeyness that makes it a star on any table. For extra depth, you can blend cheddar with Gruyère or Monterey Jack.

Kosher Salt

Just a pinch enhances every other flavor in the dish. Since the soups and fried onions already contain salt, a modest amount is all that’s needed.

French Fried Onions

These crispy, golden onions are the signature topping that completes the dish. They provide texture, crunch, and a satisfying contrast to the creamy base. Mixing some into the casserole ensures that every bite has a little crunch, while the topping stays crisp and golden after baking.

Kitchen Tools You’ll Need

Before starting, gather these essential tools for an easy, mess-free cooking process:

• 9×13-inch baking dish (or similar size)
• Large mixing bowl
• Measuring cups and spoons
• Mixing spoon or spatula
• Can opener
• Oven preheated to 350°F (175°C)

Preparation Method

This Simple Cheesy Green Bean Casserole lives up to its name — quick, easy, and absolutely foolproof.

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Lightly grease your baking dish with butter, oil, or nonstick spray. This ensures the casserole won’t stick and makes cleanup effortless.

Step 2: Combine the Creamy Base

In a large mixing bowl, combine:

• 1 can cream of mushroom soup
• 1 can cream of celery soup
• 1 cup shredded sharp cheddar cheese
• 1/4 tsp kosher salt

Stir until the mixture becomes smooth and uniform. This creamy blend will serve as the flavor-packed sauce that coats every bean.

💡 Tip: If you prefer a thinner sauce, stir in 2–3 tablespoons of milk to loosen the texture slightly before adding the beans.

Step 3: Add the Green Beans and Fried Onions

Add the drained green beans to the soup-and-cheese mixture. Gently fold with a spatula until the beans are evenly coated in the creamy sauce. Then, stir in 3 oz of French fried onions (about half of the total onion amount). This ensures that some crunch and roasted onion flavor are baked into the casserole itself.

Step 4: Transfer to Baking Dish

Pour the mixture into your greased baking dish and spread evenly. The layer should be smooth on top to promote even baking.

Step 5: Bake the Casserole

Place the dish on the center rack of your preheated oven and bake uncovered for 25–30 minutes, until the sauce is hot and bubbling around the edges. The aroma will be irresistible — creamy, cheesy, and savory.

Step 6: Add the Topping

Carefully remove the casserole from the oven. Sprinkle the remaining 1 cup shredded cheddar cheese evenly over the surface. Then, top with the final 3 oz of French fried onions.

Return the dish to the oven and bake for an additional 10 minutes, or until the cheese is fully melted and the onions are a deep golden brown.

🔥 Pro Tip: For an extra-crispy topping, you can broil the casserole for 1–2 minutes at the end of baking — just keep a close eye on it to avoid burning.

Step 7: Rest and Serve

Allow the casserole to cool for 5–10 minutes before serving. This helps the sauce set slightly, making it easier to scoop and serve neat portions. Serve warm, directly from the dish, and watch it disappear in no time!

Flavor Profile

Every forkful of this cheesy green bean casserole offers a delightful combination of textures and tastes:

• The green beans provide a tender, slightly sweet contrast to the rich sauce.
• The soups create a creamy, savory foundation.
• The sharp cheddar adds depth and richness.
• The crispy onions crown it all with a perfect crunch.

It’s indulgent yet comforting, classic yet just a touch more luxurious thanks to the cheese.

Tips for Success

1. Drain the green beans well.
   Extra liquid from canned beans can thin the sauce too much. Draining — and even lightly patting them dry — ensures the casserole stays thick and creamy.
2. Use freshly grated cheese.
   Pre-shredded cheese often contains anti-caking agents that prevent smooth melting. Grating your own cheese makes for a creamier texture.
3. Adjust salt carefully.
   Between the soups, cheese, and onions, the dish already contains salt. Always taste the sauce before adding extra.
4. Add a flavor boost.
   Mix in a splash of soy sauce, Worcestershire sauce, or garlic powder for extra depth.
5. Make ahead for easy entertaining.
   You can assemble the casserole up to 24 hours in advance (without the topping). Cover and refrigerate, then bake right before serving.

Variations to Try

This recipe is a great base for experimentation. Try these simple twists to suit your preferences or occasion:

1. Bacon and Cheddar Green Bean Casserole

Add 1/2 cup of cooked, crumbled bacon to the mixture before baking. The smoky, salty flavor pairs perfectly with the creamy sauce.

2. Spicy Kick

Stir in a pinch of cayenne pepper, crushed red pepper flakes, or diced jalapeños to give your casserole a subtle heat.

3. Garlic and Herb Infusion

Sauté a clove or two of minced garlic in butter and add it to the base mixture. Fresh herbs like thyme or parsley also brighten up the flavor.

4. Creamier Version

Mix 1/4 cup of sour cream or cream cheese into the sauce for a richer, more indulgent texture.

5. Vegetarian Upgrade

Use organic cream soups or homemade mushroom sauce for a cleaner, meat-free dish.

6. Crunchy Topping Mix

Combine panko breadcrumbs with melted butter and sprinkle over the cheese before baking. It adds a bakery-style crispness to the top layer.

Serving Suggestions

This Simple Cheesy Green Bean Casserole pairs beautifully with a wide range of main dishes and sides. Here are a few perfect pairings:
