Cajun Salmon

If you are anything like me, you are always looking for ways to get more fish into your weekly menu! I usually don’t cook it often enough since it’s best cooked the day of, but I have a feeling that will change now that I have discovered how easy it is to make sheet pan meals with salmon!

This Cajun salmon sheet pan meal could not be easier to make! And what is even better – the clean-up takes literally a second (thanks to the parchment paper)!

When I took this Cajun salmon out of the oven Dave proclaimed “wow that is the first salmon dish that I’m actually excited to eat”. Yeah he doesn’t love seafood as much as I do. But hearing that I knew I had to share this recipe with you!

I actually have a tip on how to make the most perfectly cooked flaky, juicy salmon below!

How do you make this Cajun Salmon Sheet Pan Meal in 30 minutes?

The key to making this Cajun salmon sheet pan meal in 30 minutes is to use a hot oven and start the potatoes before the rest of the ingredients!

  • Preheat the oven to 450F.
  • Cut the potatoes in half (to reduce the cooking time)
  • Line a rimmed baking sheet with parchment paper
  • Add the avocado oil, Cajun seasoning and salt to the potatoes and stir them well to combine (you can do this in a bowl or right on the parchment paper)
  • Cook the potatoes in the 450F oven for 15 minutes.
  • While the potatoes cook, prepare the green beans by trimming the ends if necessary.
  • After the potatoes cook for 15 minutes, remove the baking sheet from the oven.
  • Add the defrosted salmon and cover in salt and Cajun seasoning.
    • I like to sprinkle with my fingers to evenly distribute the seasoning. You can also use a pastry brush to distribute the Cajun seasoning.
  • Top the potatoes with the trimmed green beans and cook the entire sheet pan meal in the oven for 12 minutes.
  • Remove the sheet pan from the oven and squeeze fresh lime juice over the entire dish. Sprinkle the green beans with salt and stir the green beans and potatoes together.
  • Serve hot or cold!

Cauliflower florets can be used in place of the baby potatoes in this recipe! If you choose to use cauliflower instead, simply roast the cauliflower for 10 minutes before adding the salmon and green beans to the pan.

How to make sure you have moist, flaky salmon?

The trick is to allow your salmon to fully defrost in the fridge for at least 24 hours. After the salmon is defrosted, allow it to come to room temperature for about 30 minutes before cooking. Because there will be less of a temperature difference in the fish in cooking, the fish stays moist and flaky!

How to choose salmon at the grocery store?

I almost always buy my salmon frozen. This way I don’t have to rush to use it within 1-2 days of grocery shopping!

Depending on where you live and where you are shopping, most of the fresh salmon being sold at the grocery store was previously frozen (and defrosted before selling to you). I like to bypass this by just buying it frozen!

Always buy wild-caught salmon. It’s higher in Omega-3’s and the salmon are naturally that bright pink/orange color from the shrimp and krill they eat in the wild. Farm caught salmon has a dye added to their feed to attain that bright color (otherwise they would be grey and boring looking).

After defrosting, the salmon should not have a fishy smell or brown spots. This is a sign the salmon has started to spoil.

If you don’t love green beans (or don’t have them on hand) you could also use:

  • Asparagus, broccoli, bell peppers, mushrooms
