Salmon Casserole Recipe With Rice: One-Dish Creamy Bake with Flaky Fish

This one-dish bake transforms simple ingredients into a creamy, satisfying meal with minimal effort. I developed this method after years of testing casserole variations, focusing on perfect texture and flavor balance.

The rice absorbs the rich, savory broth while baking, creating a tender base for the flaky salmon. Layering the ingredients properly ensures even cooking and maximum flavor in every bite.

You’ll end up with a golden-topped casserole where the salmon stays moist and the rice becomes perfectly tender. The creamy sauce ties everything together beautifully.

Ideal for busy weeknights or when you want a comforting, no-fuss dinner. This dish delivers on both taste and convenience.

Ingredients for Salmon Casserole Recipe with Rice

Fresh salmon, creamy rice, and a handful of pantry staples create this elegant one-dish meal.

The salmon quality matters—look for wild-caught fillets with vibrant color and no fishy odor. Whole Foods or Trader Joe’s consistently stock excellent options. For the rice, jasmine or basmati work well too (just adjust liquid slightly). The heavy cream is non-negotiable for that luxurious texture—skip the substitutions here. Fresh dill from the produce section adds brightness that dried can’t match.

No salmon? Cod or halibut hold up well in this bake. Short on time? Pre-cooked rice works—just reduce the broth by half. For a lighter version, half-and-half plus a cornstarch slurry mimics heavy cream’s thickness. The Dijon mustard can be swapped for whole-grain if that’s your preference (the seeds add nice texture).

Assemble and bake immediately, or prep components separately up to 1 day ahead. Leftovers keep 3-4 days refrigerated—the rice soaks up more liquid over time. Reheat covered at 350°F for best texture.

Step-by-Step Instructions for Salmon Casserole with Rice

This method ensures a creamy, flaky result with perfectly cooked rice every time.

Step 1: Prepare the Rice Base

Preheat your oven to 375°F. In a large oven-safe skillet, melt the 0.25 cup butter over medium heat. Add the 1 whole yellow onion, finely diced, and sauté for 4-5 minutes until translucent and fragrant.

Stir in the 3 cloves garlic cloves and cook for 30 seconds until aromatic. Add the 1.5 cups long-grain white rice and toast for 2 minutes, stirring constantly, until the grains appear slightly opaque. This step enhances the nutty flavor of the rice.

Step 2: Create the Creamy Sauce

Sprinkle the 2 tbsp all-purpose flour over the rice mixture and stir to coat evenly. Gradually pour in the 2 cups chicken broth and 1.5 cups heavy cream, whisking continuously to prevent lumps. The sauce should begin to thicken slightly within 2-3 minutes.

Add the 1 tbsp Dijon mustard, 1 tbsp lemon juice, 1 tsp kosher salt, 0.5 tsp black pepper, and 0.5 tsp paprika. Stir well to distribute the seasonings evenly. The mixture should be smooth and slightly glossy, coating the back of a spoon.

Step 3: Add the Salmon and Bake

Arrange the 1.5 lb salmon fillets on top of the rice mixture, pressing them gently into the sauce. Ensure the fillets are spaced evenly to allow for uniform cooking. The sauce should come about halfway up the sides of the salmon.

Cover the skillet tightly with foil or a lid and transfer it to the preheated oven. Bake for 25-30 minutes until the rice is tender and has absorbed most of the liquid. The salmon should flake easily with a fork and reach an internal temperature of 145°F.

Step 4: Finish and Garnish

Remove the casserole from the oven and let it rest, covered, for 5 minutes. This allows the rice to finish absorbing any remaining liquid and the salmon to stay moist. The rice should be tender, and the sauce should have thickened to a creamy consistency.

Sprinkle the 0.25 cup fresh dill evenly over the top just before serving. The dill adds a bright, fresh contrast to the rich, creamy casserole. Serve immediately, ensuring each portion includes both salmon and rice for a balanced bite.

Essential Equipment for Perfect Results

Oven-Safe Skillet

I always use my 12-inch Lodge cast iron skillet for this dish—it goes from stovetop to oven seamlessly and distributes heat perfectly. A stainless steel oven-safe skillet with a tight-fitting lid works too if you prefer lighter cookware. 💡

Mixing Bowls

Have a large mixing bowl ready for prepping ingredients. I love my Pyrex glass set from New Seasons Market—they’re durable and nest beautifully in my Portland kitchen cabinets. The 3-quart size is perfect for combining the rice and liquid ingredients.

Whisk & Wooden Spoon

A sturdy silicone whisk prevents lumps when making the creamy sauce. I pair it with a wooden spoon for stirring the rice—Grandma’s trick to avoid scratching the skillet. These are my go-to tools for any stovetop casserole.

Measuring Tools

Precise measurements matter here. I use OXO Good Grips measuring cups and spoons—the magnetic set stays organized in my drawer. A liquid measuring cup with a spout makes pouring the broth and cream mess-free.

Thermometer

For perfect salmon every time, I rely on my ThermoWorks Instant Read to check the 145°F internal temperature. It’s a game-changer for ensuring the fish is cooked through but still flaky. No more guessing! 🌡️

Serving Utensils

A wide spatula helps serve portions without breaking the salmon. I keep a large serving spoon handy too for the rice and sauce. These small tools make plating this one-dish wonder effortless.
