Ingredients You’ll Need

This easy salmon casserole relies on a handful of pantry staples and fresh ingredients to create its signature flavor. Everything comes together to make a creamy, comforting dish with just the right mix of texture and taste.

For the Casserole Base

• Small Shell-Shaped Pasta: These cute little shells hold the creamy sauce in every bite, making the dish extra satisfying.
• Kosher Salt: Don’t forget to season your pasta water, it’s the first step to building flavor!
• Cooked and Flaked Fresh Salmon: The star of the dish. Use baked, grilled, or poached salmon. (Tip: Canned salmon works too if you’re short on time.)
• Condensed Cream of Celery Soup: This undiluted base is what makes the sauce so creamy and savory without extra effort.
• Mayonnaise: Adds richness and a slight tang that blends perfectly with the soup.
• Milk: Thins the sauce just enough. Use the empty soup can to measure, easy and mess-free.
• Shredded Sharp Cheddar Cheese: Melts into the sauce and gives it that cheesy pull and bold flavor.
• Frozen Peas: Sweet and colorful. Toss them in straight from the freezer, no thawing needed.
• Shredded Carrot & Finely Diced Onion: These aromatics boost flavor while blending into the creamy mix.

For the Crunchy Topping & Garnish

• Ritz Crackers: Crushed over the top for that golden, buttery crunch that’s a signature of this salmon casserole with Ritz crackers.
• Old Bay Seafood Seasoning: A light sprinkle over the topping adds depth and classic seafood flair.
• Fresh Snipped Chives: Brightens up the dish and adds a mild, oniony finish.

How to Make Salmon Casserole (Step-by-Step)

This creamy salmon casserole comes together quickly with easy steps and simple ingredients. Whether you’re using fresh or canned salmon, this recipe guarantees a flavorful, comforting dinner that’s ready in under an hour.

Step 1: Prep Oven and Pasta

Preheat your oven to 375°F (190°C) and grease a 9×13-inch or 2-quart casserole dish with nonstick spray or a little oil.
Cook the shell pasta in a large pot of salted boiling water until just al dente, firm but not overcooked. Drain and set aside.

Step 2: Make the Creamy Sauce

In a large mixing bowl, whisk together the undiluted cream of celery soup, mayonnaise, milk, and half of the shredded cheddar cheese. Mix until smooth and creamy. This forms the base of your flavorful, cheesy sauce.

Step 3: Combine Ingredients

Gently fold in the cooked and flaked salmon, shredded carrot, diced onion, and frozen peas. Stir just enough to combine, be careful not to break up the salmon too much. This blend adds protein, veggies, and subtle sweetness to your casserole.

Step 4: Assemble the Casserole

Add the drained pasta to the bowl with the salmon mixture. Stir gently until every shell is coated in that creamy goodness.
Pour the mixture into your prepared baking dish, smoothing it out evenly.

Step 5: Add the Topping and Bake

Sprinkle the remaining shredded cheddar cheese over the top for extra meltiness.
Then, add the crushed Ritz crackers in an even layer.
Dust generously with Old Bay seasoning to finish.
Bake uncovered for 25-30 minutes, or until hot, bubbly, and golden brown on top.

Step 6: Garnish and Serve

Let it rest for about 5 minutes after baking so it sets slightly and is easier to serve.
Top with freshly snipped chives (or parsley if you prefer), and serve warm.

Perfect as a salmon pasta bake or a cozy leftover salmon recipe, this casserole is easy, delicious, and always a hit at the table.

Recipe Tips and Ingredient Swaps

Want to make this easy salmon casserole your own? Here are some expert tips and simple swaps to help you adapt the recipe to fit your needs, pantry, or dietary preferences.

• Use canned salmon for convenience and savings. Just make sure it’s boneless and well-drained. It works just as well as fresh and still gives you that rich, flaky texture.
• Add sautéed mushrooms or celery if you like a bit more texture and savory depth. Just cook them lightly before mixing into the base.
• Make it gluten-free by swapping in your favorite gluten-free shell pasta and using gluten-free crackers in place of Ritz. Be sure your condensed soup is also labeled gluten-free.
• Prep it ahead of time. You can assemble the full casserole (minus the cracker topping) up to 24 hours in advance. Store it covered in the fridge, then add the topping and bake when ready.

These tips make this dish even more versatile, whether you’re feeding a crowd, sticking to a budget, or working around food sensitivities, this salmon casserole with cheese is flexible and always comforting.

Is Salmon Casserole Healthy?

Yes, salmon casserole can be a balanced and satisfying meal. Thanks to the salmon and cheese, it’s high in protein, while the carrots and peas add fiber and nutrients. If you’re looking to reduce calories or fat, simply swap in light mayo and skim milk without sacrificing the creamy texture.
