Ingredients

Here’s what you’ll need to make this delicious bake:

1 large salmon fillet (about 1–1.5 lbs): The star of the show, rich and flaky.
1 lb large shrimp, peeled and deveined: Adds a sweet, tender contrast.
2 tbsp olive oil: For brushing and tossing to keep things moist.
2 tbsp butter, melted: Adds richness and helps the spices cling.
3 cloves garlic, minced: For that irresistible savory punch.
1 tbsp Cajun seasoning: The bold, spicy blend that brings everything together.
½ tsp smoked paprika: Adds smoky depth without overpowering.
½ tsp chili flakes (optional): For a fiery touch if you like extra heat.
1 medium onion, sliced: Roasts up sweet and tender beneath the seafood.
1 tbsp lemon juice: Brightens the whole dish with a fresh zing.
Salt and black pepper to taste: Essential for seasoning.
2 tbsp fresh parsley, chopped: For a pop of color and freshness.
Lemon wedges for serving: To squeeze over each bite.

How to Make Spicy Cajun Salmon & Shrimp Bake

Follow these easy steps, and you’ll have dinner ready before you know it:

Preheat your oven to 400°F (200°C). Line a baking tray with foil for easy cleanup.
Arrange the sliced onions evenly on the tray. Place the salmon fillet right on top of the onions—this creates a flavorful bed that keeps the fish moist.
Brush the salmon generously with olive oil and melted butter. Then sprinkle on the Cajun seasoning, smoked paprika, salt, and black pepper. Make sure to coat it well for that perfect spicy crust.
In a bowl, toss the shrimp with minced garlic, olive oil, Cajun seasoning, and chili flakes if you’re using them. Spread the shrimp around the salmon on the baking tray.
Bake everything for 12 to 15 minutes. You’ll know it’s done when the salmon flakes easily with a fork and the shrimp turn a lovely pink color.
Once out of the oven, drizzle fresh lemon juice over the seafood and sprinkle with chopped parsley. Serve with lemon wedges on the side for extra brightness.

Pro tip: Keep an eye on the shrimp—they cook quickly and can get rubbery if overdone. If you want to add a little extra something, try serving this bake alongside some buttery mashed potatoes or a fresh green salad for a balanced meal.

Substitutions & Additions

If you’re feeling creative or working with what you have, here are some ideas:

Swap salmon for another firm fish like cod or halibut for a milder flavor.
Use scallops in place of shrimp for a buttery, delicate bite.
Add sliced bell peppers or cherry tomatoes on the tray for more color and freshness.
Mix in a splash of white wine or a touch of cream with the butter for a richer sauce.
If you love spice, try a dash of cayenne pepper or a drizzle of hot honey right before serving.

If you want to round out your meal with a light pasta, you might enjoy a dish like Lemon Ricotta Spinach Pasta, which pairs beautifully with the bold Cajun flavors.

Tips for Success

Don’t skip the foil lining—it makes cleanup so much easier, especially with buttery Cajun spices involved.
Make sure your shrimp are fully thawed and patted dry before tossing with seasoning to avoid watery results.
For a perfectly flaky salmon, avoid overbaking. Check at the 12-minute mark and adjust as needed.
You can prep the seasoning mix and garlic ahead of time to speed up dinner on busy nights.
Serve immediately for the best texture, but leftovers reheat nicely in a skillet or oven.

How to Store Spicy Cajun Salmon & Shrimp Bake

If you have leftovers—which can be hard to resist!—here’s how to keep them fresh:

Store in an airtight container in the fridge for up to 2 days.
Reheat gently in the oven at 300°F (150°C) or on the stovetop to avoid drying out the seafood.
For longer storage, freeze in a sealed container for up to 1 month. Thaw overnight in the fridge before reheating.

FAQs

Can I make this recipe without the shrimp?

Absolutely! The salmon shines on its own, but the shrimp add a wonderful variety. You can simply bake the salmon with the onions and Cajun spices for a delicious meal.

How spicy is this dish?

This bake has a moderate heat level thanks to the Cajun seasoning and optional chili flakes. You can adjust the spice by using less seasoning or skipping the chili flakes if you prefer milder flavors.
