Ingredients You’ll Need

These ingredients are fresh, simple, and easy to find at any grocery store.

• 2 white fish fillets (Cod, Tilapia, or Mahi-mahi)
• 2 medium sweet potatoes, sliced thin
• 2 tablespoons extra virgin olive oil, divided
• 1 tablespoon Cajun seasoning blend
• 0.5 teaspoon sea salt
• 0.25 teaspoon cracked black pepper
• 1 lemon, cut into wedges
• 1 tablespoon fresh flat-leaf parsley, chopped

Step-by-Step

1. Preheat the oven to 400°F (200°C) and line a baking sheet.
2. Toss sweet potato slices with 1 tablespoon oil, salt, and pepper.
3. Arrange slices in a single layer and bake for 20-25 minutes.
4. Flip the chips halfway through until they are golden and crisp.
5. Pat fish dry and coat evenly with the Cajun seasoning blend.
6. Heat remaining oil in a skillet over medium-high heat.
7. Sear fish for 3 to 4 minutes per side until flaky.
8. Plate the fish with chips, parsley, and fresh lemon wedges.

Best Ways to Enjoy It

Serve this dish warm while the chips are still crunchy. The fresh lemon juice really wakes up the smoky Cajun spices.

Add a simple green salad on the side for extra crunch. You can also serve it with a cool yogurt dip. It is a vibrant, colorful plate that looks beautiful on the table.

Storage & Reheating

Store any leftover fish in an airtight container for two days. The chips are best enjoyed immediately for the best texture.

To reheat, use a 350°F oven for about 10 minutes. This helps the fish stay moist and the chips stay crisp. Avoid the microwave to prevent the potatoes from getting soggy.

Recipe Tips

• Don’t skip patting the fish dry for a better sear.
• Slice potatoes evenly so they all finish baking at once.
• Use a cast-iron skillet for the most flavorful crust.
• Ensure the potatoes are in a single layer on the pan.
• Double the spice blend if you love extra heat.
• Swap the parsley for cilantro for a different fresh finish.
• Add a side of steamed broccoli for more greens.

Ways to Switch It Up

• Swap sweet potatoes for zucchini rounds for a lower-carb option.
• Use salmon instead of white fish for extra healthy fats.
• Replace Cajun spice with lemon pepper for a milder flavor.
• Try air-frying the chips at 375°F for 15 minutes instead.

FAQs

Can I use frozen fish?

Yes, you can use frozen fillets for this recipe. Just make sure to thaw them completely in the fridge. Pat them very dry before adding the spices.

How do I know when the fish is done?

The fish should reach an internal temperature of 145°F. It will also look opaque and flake easily with a fork. Do not overcook it to keep it tender.

I hope this fresh meal brings a little spark to your weeknight. It is simple, clean, and so satisfying to eat. Happy cooking!
