2. Toss sweet potato slices with 1 tablespoon oil, salt, and pepper.
3. Arrange in a single layer and bake for 20 to 25 minutes.
4. Flip the potatoes at the 12-minute mark until golden and crisp.
5. Pat fish dry and apply Cajun seasoning evenly to both sides.
6. Heat remaining oil in a skillet over medium-high heat.

Best Ways to Enjoy It

Serve this dish warm while the chips are extra crispy. The lemon wedges are not just a garnish; squeeze them over!

The bright citrus cuts through the bold Cajun spices perfectly. Pair it with a fresh garden salad for a complete meal.

How to Store Leftovers

Store the fish and chips in separate airtight containers. They will keep in the fridge for up to two days.

Reheat the chips in the oven to keep them from getting soggy. The fish is great cold over a lunch salad too!

Recipe Tips

• Always pat your fish dry for the perfect crust.
• Slice sweet potatoes very thin for maximum crunch.
• Don’t crowd the baking sheet or they will steam.
• Use a cast-iron skillet for the best sear.
• Check the fish temperature to avoid overcooking it.
• Press the seasoning into the fish so it sticks.

Ways to Switch It Up

• Try salmon fillets for a boost of healthy fats.
• Add a pinch of cayenne if you want extra heat.
• Use an air fryer for the sweet potato chips.
