Cajun Catfish with Roasted Baby Potatoes: Bold, Spicy, and Ready in Under an Hour
A Skillet Seared Dinner That Brings the Bayou to Your Table
Some dinners taste like effort and some taste like flavor, and this Cajun catfish recipe is proof that the two do not always go hand in hand. Tender catfish fillets get coated in a bold, smoky spice blend, seared until the edges turn deep golden brown, then served alongside crispy roasted baby potatoes and a squeeze of fresh lemon. It is a weeknight dinner that tastes like it came from a restaurant kitchen in New Orleans.
What makes Cajun seasoned catfish so satisfying is the contrast between the crackly, spiced crust and the flaky, mild fish underneath. The seasoning does all the heavy lifting here, so you do not need a long list of specialty ingredients or hours of prep. Just a hot skillet, a handful of pantry spices, and a little patience while the fillets sear.
Catfish is a mild, tender fish that works especially well with bold Cajun spices. The smoky paprika, garlic, onion, and pepper create a flavorful crust without overpowering the fish. It is also a lean source of protein and provides nutrients such as vitamin B12 and selenium. You can learn more about catfish nutrition in this Healthline guide.
Cajun cooking traces its roots back to the Acadian settlers who brought their French culinary traditions to Louisiana. Over time, those techniques blended with local ingredients and bold spice blends to create the rustic, hearty style of cooking known today. Catfish became a natural fit for this cuisine since it was abundant in the region’s rivers and lakes, and its firm, mild flesh held up beautifully to smoky, peppery seasoning.
This Cajun catfish recipe carries that same spirit forward, turning a humble fillet into something full of character. Pair it with roasted potatoes for a complete, satisfying plate, or swap in your own favorite side. However you serve it, this easy catfish recipe turns an ordinary weeknight into something worth savoring.

Frequently Asked Questions
Can I use a different type of fish for this Cajun catfish recipe?
Yes. Tilapia and red snapper both work well as substitutes if catfish is not available. Both are mild, flaky white fish that hold up nicely to the bold cajun seasoning and sear in about the same amount of time.
Is cajun seasoned catfish very spicy?
It has a noticeable kick from the cayenne pepper, but it is not overwhelmingly hot. If you prefer a milder dish, reduce the cayenne by half. If you love heat, feel free to add an extra pinch or a dash of hot sauce when serving.
Can I bake the catfish instead of pan searing it?
Yes. Arrange the seasoned fillets on a parchment lined baking sheet and bake at 400 degrees for about twelve to fifteen minutes, until the fish flakes easily with a fork. You will lose a bit of the buttery crust, but it is a simple hands off alternative.
Can I make the cajun seasoning ahead of time?
Absolutely. Mix a larger batch of the spice blend and store it in an airtight jar for up to three months. Having it on hand makes it easy to season chicken, shrimp, or vegetables anytime you want that same smoky, peppery flavor.
What if I do not have baby potatoes?
Regular potatoes cut into similar sized chunks will work just as well. Just make sure the pieces are roughly the same size so they roast evenly in the same amount of time.
How do I know when the catfish is fully cooked?
The fillets are done when they turn opaque and flake easily with a fork, which usually takes about three to four minutes per side in a hot skillet. An instant read thermometer should register 145 degrees at the thickest part.
Can I make this cajun catfish recipe ahead of time?
The potatoes can be roasted ahead and reheated, but the fish is best seared fresh right before serving. This keeps the crust crisp and the fillets from drying out, since fish tends to lose its texture when reheated.
How long do leftovers last in the fridge?
Store any leftover catfish and potatoes in an airtight container in the refrigerator for up to two days. Reheat gently in a skillet or oven rather than the microwave to help the fish keep its texture.
Notes and Tips
Pat the catfish fillets dry before seasoning so the spice blend sticks evenly and the fish sears instead of steams. Use a heavy skillet, like cast iron, for the best golden crust on the fillets. Cut the baby potatoes into even halves so they cook at the same rate in the oven. Do not overcrowd the skillet when searing, since this traps steam and keeps the crust from forming properly. A squeeze of fresh lemon juice right before serving brightens up all of the smoky, peppery flavor.

Ingredients
- 4 catfish fillets (tilapia or red snapper also work)
- 1.5 pounds baby potatoes, halved
- 2 tablespoons paprika
- 1 teaspoon cayenne pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- 1 teaspoon dried oregano
- 2 teaspoons salt, divided
- 1 teaspoon black pepper, divided
- 3 tablespoons butter or oil, for searing the fish
- 2 tablespoons olive oil, for the potatoes
- Lemon wedges, to serve
The catfish fillets are the centerpiece of this cajun catfish recipe, so look for ones that are similar in thickness for even cooking. Paprika and cayenne pepper build the smoky, spicy base of the seasoning, while garlic powder, onion powder, thyme, and oregano round it out with savory depth. Butter gives the fillets their rich, golden crust as they sear, and a squeeze of lemon at the end keeps everything tasting bright rather than heavy.
Instructions
1. Mix the Cajun Seasoning and Coat the Fillets
In a small bowl, stir together the paprika, cayenne pepper, garlic powder, onion powder, thyme, oregano, half the salt, and half the black pepper until fully combined. Pat the catfish fillets dry with a paper towel, then press the seasoning blend evenly over both sides of each fillet, making sure every inch is coated. Set the fillets aside on a plate or cutting board while you prepare the potatoes, allowing the spices a few minutes to settle into the fish.
2. Toss and Roast the Baby Potatoes
Preheat the oven to 425 degrees. In a large bowl, toss the halved baby potatoes with the olive oil and the remaining salt and black pepper until every piece is well coated. Spread the potatoes in a single layer on a parchment lined baking sheet, cut sides down for the best caramelization. Roast for twenty five to thirty minutes, until the potatoes are golden brown and tender when pierced with a fork.
3. Sear the Catfish and Plate with Lemon
While the potatoes finish roasting, melt the butter in a large skillet over medium high heat until it begins to foam slightly. Add the seasoned catfish fillets and sear for three to four minutes per side, until a deep golden crust forms and the fish flakes easily with a fork. Transfer the fillets to plates alongside the roasted potatoes, then finish with a few fresh lemon wedges squeezed right over the top before serving.
