Tasty Cajun Salmon and Shrimp Bake Recipe for a Flavorful Dinner

A good seafood dinner should feel special without turning the kitchen into a project. This Cajun salmon and shrimp bake does exactly that. It gives you buttery salmon, juicy shrimp, smoky seasoning, sweet roasted vegetables, and a lemony pan sauce in one baking dish.

The best part is how little effort it takes. You season everything, layer it in a pan, bake in stages, and finish with fresh lemon and herbs. The salmon stays tender, the shrimp cook quickly, and the Cajun spices bring enough heat and depth to make the whole meal taste bold.

This is the kind of recipe that works for a weeknight dinner but still feels good enough for guests. Serve it with rice, roasted potatoes, garlic bread, or a crisp salad, and dinner is ready.

A one-pan seafood bake makes a bold dinner feel easy.

Why this Cajun salmon and shrimp bake works so well

Salmon and shrimp are a natural match because they give you two different textures in one dish. Salmon is rich and flaky. Shrimp are sweet, firm, and quick-cooking. Cajun seasoning ties them together with smoked paprika, garlic, onion, herbs, and a gentle kick of cayenne.

The key is timing. Salmon usually needs a little more time in the oven than shrimp, so this recipe gives the salmon and vegetables a head start. The shrimp go in later so they stay tender instead of turning rubbery.

You also get flavor from three places:

• Cajun seasoning for smoky spice

• Garlic butter for richness

• Lemon juice for brightness

  
  

That balance keeps the dish bold without feeling heavy. If you like more heat, add cayenne or hot sauce. If you prefer a milder dinner, use a low-salt Cajun seasoning and skip the extra pepper.

Ingredients you need

This recipe serves 4 people. It can stretch to 5 if you serve it with a hearty side like rice, pasta, or potatoes.

Seafood

• 4 salmon fillets, about 6 ounces each

• 1 pound large shrimp, peeled and deveined

• 1 tablespoon olive oil

• 1 tablespoon Cajun seasoning for the salmon

• 2 teaspoons Cajun seasoning for the shrimp

  
  

Choose salmon fillets that are similar in thickness so they cook evenly. Skin-on or skinless both work. If using frozen shrimp, thaw them fully and pat them dry before seasoning.

Vegetables

• 1 red bell pepper, sliced

• 1 yellow bell pepper, sliced

• 1 small red onion, sliced

• 1 cup cherry tomatoes

• 1 small zucchini, sliced into half-moons

• 1 tablespoon olive oil

• 1 teaspoon Cajun seasoning

• 1/2 teaspoon kosher salt, only if your Cajun seasoning is low-salt

• 1/4 teaspoon black pepper

  
  

These vegetables roast quickly and pair well with seafood. You can also use broccoli florets, asparagus, green beans, or corn on the cob cut into small rounds.

Garlic butter sauce

• 4 tablespoons unsalted butter, melted

• 3 garlic cloves, minced

• 1 tablespoon lemon juice

• 1 teaspoon honey

• 1 teaspoon Cajun seasoning

• 1/2 teaspoon smoked paprika

• 1 tablespoon chopped parsley

• Lemon wedges for serving

  
  

The honey does not make the dish sweet. It rounds out the spice and helps the seafood caramelize lightly in the oven.

How to make Cajun salmon and shrimp bake

This Tasty Cajun Salmon and Shrimp Bake Recipe comes together in about 35 minutes, including prep. Have everything cut and seasoned before the pan goes into the oven. Once the salmon starts baking, the rest moves quickly.

Heat the oven and prepare the pan

Preheat the oven to 400°F. Lightly grease a large baking dish or rimmed sheet pan with olive oil or cooking spray.

A sheet pan gives you more browning because the ingredients spread out. A baking dish keeps more juices in the pan and creates a saucier finish. Both work well.

Season the vegetables

Add the bell peppers, red onion, tomatoes, and zucchini to the pan. Drizzle with olive oil, then sprinkle with Cajun seasoning, salt if needed, and black pepper.

Toss until the vegetables are coated. Spread them into an even layer, leaving space in the center for the salmon.

Roast the vegetables for 8 minutes. This gives them a head start so they soften and release flavor before the seafood goes in.

Seasoning the vegetables first builds flavor from the bottom of the pan.

Season the salmon

While the vegetables start roasting, pat the salmon fillets dry with paper towels. This helps the seasoning stick and gives the salmon a better texture.

Rub the salmon with olive oil, then coat each fillet with Cajun seasoning. Place the salmon in the pan among the vegetables after the first 8 minutes of roasting.

Bake for 10 minutes.

Add the shrimp

Pat the shrimp dry. Toss them in a bowl with Cajun seasoning and a small drizzle of olive oil.

After the salmon has baked for 10 minutes, remove the pan from the oven. Scatter the shrimp around the salmon in a single layer. Do not pile them up, or they may steam instead of bake.

Pour on the garlic butter

In a small bowl, stir together the melted butter, minced garlic, lemon juice, honey, Cajun seasoning, and smoked paprika.

Spoon the garlic butter over the salmon and shrimp. Try to get a little over everything, including the vegetables.

Return the pan to the oven and bake for 6 to 8 minutes, until the shrimp are pink and opaque and the salmon flakes easily with a fork.

For food safety, fish should reach an internal temperature of 145°F. Use an instant-read thermometer at the thickest part of the salmon if you want the most reliable result.

Finish with lemon and herbs

Remove the pan from the oven. Sprinkle with chopped parsley and squeeze fresh lemon over the top.

Let the salmon rest for 3 minutes before serving. This helps the juices settle and makes the fish easier to plate.

The shrimp go in near the end so they stay juicy.

The best seasoning for this recipe

Cajun seasoning can vary a lot. Some blends taste smoky and herb-forward. Others are very salty or spicy. If you are using a store-bought blend for the first time, taste a tiny pinch before adding extra salt.

A good Cajun blend often includes:

• Paprika

• Smoked paprika

• Garlic powder

• Onion powder

• Dried oregano

• Dried thyme

• Black pepper

• Cayenne pepper

• Salt

  
  

If your seasoning is salt-free, add salt to the seafood and vegetables. If it already tastes salty, skip extra salt until the end.

Quick homemade Cajun seasoning

If you want to make your own, stir together:

• 2 tablespoons paprika

• 1 tablespoon garlic powder

• 1 tablespoon onion powder

• 1 tablespoon dried oregano

• 1 tablespoon dried thyme

• 1 teaspoon smoked paprika

• 1 teaspoon black pepper

• 1/2 teaspoon cayenne pepper

• 1 teaspoon kosher salt

  
  

Use what you need for the recipe and store the rest in a sealed jar. For a spicier blend, increase the cayenne. For a milder version, cut it in half.

Tips for tender salmon and juicy shrimp

Seafood can go from perfect to overcooked fast. A few simple habits make a big difference.

Pat the seafood dry. Moisture on the surface waters down the seasoning and prevents good texture.

Use similar salmon pieces. Thin fillets cook faster than thick center-cut pieces. If the sizes vary, check the smaller ones early.

Add shrimp later. Shrimp need only a few minutes in a hot oven. Adding them at the start almost always overcooks them.

Do not crowd the pan. Crowding traps steam and keeps the ingredients from roasting. Use a large sheet pan if your baking dish feels packed.

Check early. Oven temperatures can vary. Start checking the shrimp at 6 minutes after adding them.

Finish with acid. Lemon juice wakes up the butter, seafood, and spices. It is a small step that makes the dish taste complete.

What to serve with Cajun salmon and shrimp

This bake has plenty of flavor, so keep the sides simple. Choose something that can catch the garlic butter and juices from the pan.

Side dish	Why it works
Steamed white rice	Soaks up the Cajun butter and keeps the meal classic
Brown rice	Adds a nutty flavor and a little more chew
Garlic bread	Great for scooping up the sauce
Roasted potatoes	Turns the bake into a hearty dinner
Creamy grits	Pairs well with Cajun spices and shrimp
Simple green salad	Adds crunch and freshness
Buttered corn	Sweetness balances the spice
Pasta	Makes the dish feel rich and filling

For a lighter plate, serve the salmon and shrimp over salad greens with avocado, cucumber, and a squeeze of lemon. For a comfort-style dinner, serve it over creamy mashed potatoes or Parmesan grits.

Easy variations

This recipe is flexible. Keep the same method and adjust the flavors or vegetables based on what you have.

Make it creamier

After baking, drizzle the seafood with a few spoonfuls of warm cream sauce or a light Cajun Alfredo. Keep the portion modest so the salmon and shrimp still shine.

Make it spicier

Add extra cayenne to the garlic butter or finish the dish with hot sauce. A pinch of crushed red pepper also works.

Add sausage

Sliced andouille sausage brings smoky flavor. Since it is already cooked in most cases, add it with the vegetables so it browns around the edges. Use a little less salt because sausage and Cajun seasoning can both be salty.

Use different vegetables

Asparagus, broccoli, green beans, mushrooms, and corn all work. Cut dense vegetables smaller so they cook in the same amount of time.

Make foil packets

Divide the vegetables, salmon, shrimp, and butter sauce among large sheets of foil. Seal tightly and bake on a sheet pan. This method creates a softer, steamier texture and makes cleanup easy.

Serve the seafood over rice to catch every spoonful of sauce.

How to store and reheat leftovers

Store leftovers in an airtight container in the refrigerator for up to 2 days. Seafood tastes best when reheated gently.

To reheat, place the salmon and shrimp in a covered skillet over low heat with a splash of water or broth. Warm just until heated through. You can also use the microwave at 50% power in short bursts.

Avoid reheating shrimp for too long. They can become firm and dry. If possible, remove the shrimp once warm and let the salmon heat a little longer.

Leftovers are great in:

• Rice bowls with avocado and corn

• Tacos with cabbage slaw

• Pasta with a light cream sauce

• Salad with lemon vinaigrette

• Omelets or breakfast hash
