Ingredients You’ll Need
You’ll be pleasantly surprised by how simple these ingredients are—each one plays an important role in bringing this Easy Cheesy Salmon Casserole to life, whether that’s adding creaminess, punchy flavor, or wholesome texture. With just a little prep, these kitchen staples unite to create true magic.
- Cooked salmon: Flaked, tender salmon is the star! Use leftovers or canned salmon for convenience—just make sure it’s drained and free of bones.
- Cooked pasta (rotini or elbow): Choose a shape that absorbs sauce well; both rotini and elbow macaroni trap all the creamy cheese goodness.
- Shredded cheddar cheese: This brings melty, bold flavor—the cheesier, the better!
- Cream cheese (softened): Gives an irresistibly smooth texture and mild tang that makes every scoop decadent.
- Sour cream: Adds creaminess and a little zip, balancing out the rich cheeses.
- Milk: Loosens up the mixture so everything bakes into an ultra-creamy casserole.
- Grated Parmesan cheese: Adds salty, nutty notes and depth to both the filling and the topping.
- Frozen peas: For pops of color and a gentle sweetness that pairs so well with salmon.
- Chopped celery: Brings fresh crunch and a nice savory base.
- Chopped onion: For sweet, aromatic warmth that enhances every bite.
- Lemon juice: Brightness in every forkful! It lifts and balances all that creamy richness.
- Garlic powder: A quick sprinkle infuses subtle garlicky flavor—convenient and tasty.
- Dried dill: The classic pairing with salmon! A teaspoon brings herby freshness.
- Salt and pepper: The trusty essentials—season to suit your taste.
- Breadcrumbs (optional topping): For that classic golden crunch on top. Totally optional, but oh so good!
- Melted butter (for topping): Toasts the breadcrumbs and gives your casserole a tempting, buttery finish.
How to Make Easy Cheesy Salmon Casserole
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to make sure your Easy Cheesy Salmon Casserole never sticks and those cheesy edges slide out perfectly every time.
Step 2: Mix the Casserole Base
In a large mixing bowl, add the flaked salmon, cooked pasta, shredded cheddar cheese, cream cheese, sour cream, milk, grated Parmesan, peas, celery, onion, lemon juice, garlic powder, dill, salt, and pepper. Stir everything really well, making sure every nook and cranny is covered in creamy, cheesy goodness. Don’t be afraid to use your hands or a sturdy spatula—getting all these flavors to marry together is what makes this casserole sing.
Step 3: Fill the Baking Dish
Pour your well-mixed casserole base into the greased baking dish. Spread it out evenly so every inch will bake beautifully, giving everyone a bite of salmon, veggies, and gooey cheese in every serving.
Step 4: Add the Topping
If you love a golden, crispy crust (who could resist?), toss the breadcrumbs with the melted butter in a small bowl. Sprinkle this concoction over the top for added crunch and flavor. If you want to keep it lighter or gluten-free, feel free to skip the breadcrumb layer—it’s delicious either way!
Step 5: Bake to Perfection
Slide your dish into the oven and bake for 25 to 30 minutes, until the casserole is bubbling and the topping is lightly golden. Watch for those cheesy corners—they’ll get perfectly crispy. Allow it to cool just a few minutes before serving so the flavors can settle and the casserole slices cleanly.
How to Serve Easy Cheesy Salmon Casserole

Garnishes
A simple sprinkle of fresh chopped dill or parsley over the top will add color and a burst of freshness to your Easy Cheesy Salmon Casserole. If you want an extra punch, a little grated lemon zest or an extra dusting of Parmesan just before serving creates a restaurant-worthy finish.
Side Dishes
This casserole is hearty on its own, but it pairs wonderfully with a crisp green salad, steamed asparagus, or your favorite roasted vegetables. Warm, crusty bread is perfect for scooping up extra cheesy sauce and turning dinner into a true comfort food experience.
Creative Ways to Present
For a playful twist, spoon your Easy Cheesy Salmon Casserole into individual ramekins for dinner parties or cozy meal prep. You can also serve it alongside a chilled cucumber salad in the summer, or pile it high on plates with microgreens for an elegant touch at a brunch buffet.
Make Ahead and Storage
Storing Leftovers
Leftover Easy Cheesy Salmon Casserole keeps beautifully. Transfer any remaining casserole to an airtight container and refrigerate for up to three days. The flavors actually meld and improve overnight, so your lunch the next day might taste even better!
Freezing
To freeze, let the casserole cool completely, then wrap it tightly in plastic wrap and foil or transfer to a lidded freezer-safe container. It’ll keep in the freezer for up to two months. For best results, skip the breadcrumb topping until you’re ready to bake (add it fresh before reheating).
Reheating
Reheat single servings in the microwave until hot, or pop the whole casserole back into a 350°F oven, covered, until warmed through (about 20-25 minutes if frozen or 10-15 minutes from the fridge). If desired, uncover for the last few minutes so the top crisps back up.
FAQs
Can I use canned salmon instead of cooked fresh or leftover salmon?
Absolutely! Canned salmon is a great shortcut for Easy Cheesy Salmon Casserole. Just drain it thoroughly and pick out any bits of skin or bones before mixing with the other ingredients.
Can I make this casserole gluten-free?
Yes—swap the pasta for cooked rice or your favorite gluten-free noodles, and replace regular breadcrumbs with a gluten-free option or simply leave them off for a naturally gluten-free meal.
What kind of pasta works best in this recipe?
Short pasta shapes like rotini, elbow, or even penne catch all that savory sauce and cheese. Avoid spaghetti or long noodles, as they won’t give you that classic casserole texture.
Can I add other vegetables?
Definitely! This recipe is flexible. Try adding chopped bell peppers, mushrooms, or even a handful of spinach for an extra dose of veggies without altering the creamy texture.
Is Easy Cheesy Salmon Casserole good for meal prep?
Yes! Easy Cheesy Salmon Casserole reheats very well and can be portioned out into containers for easy, satisfying lunches throughout the week. Just reheat and enjoy.

I hope you enjoy every bite of this Easy Cheesy Salmon Casserole as much as my family and friends do. Whether it’s a casual weeknight or a cozy Sunday dinner, this recipe always delivers comfort and smiles. Don’t be afraid to make it your own and share with those you love most!
