Step #8. Layer Potatoes Onto Baking Sheet

Layer the potato wedges onto the baking sheet. Do not overlap.

Step #9. Bake the Fries

Bake for 20 minutes in the preheated oven, or until golden. Flip and bake for about 10-20 more minutes, until golden and crispy. Keep an eye on them.

Step #10. Serve the Cajun Fries

Serve the Cajun fries with ranch sauce.

Since the potatoes are baked, not fried, you can control the amount of oil used. Love that Cajun zing? Adjust the spice level to your own taste.

The sauce cuts a cool contrast to these spicy hot-from-your-oven fries. They come out crispy and delicious (instead of floppy potato sticks).

We doubt you’ll have any leftovers. If you do, they can be stored in an airtight container. Keep them in the refrigerator for up to 3 days.

To reheat the fries, either lay them out in a single layer on a baking pan and warm up in the oven (400 degrees Fahrenheit for about 8 minutes) or if you want to get a crispy, crunchy fry crust, heat a teaspoon of oil in a skillet over medium heat. Add the fries, letting them crisp on the bottom completely before flipping them to crisp both sides. Remove the fries from the oil and dry on paper towels.

We love these homemade Cajun fries with ranch sauce, but we also like to mix it up once in a while. Feeling saucy? Ketchup, honey mustard, mayonnaise, and garlic aioli are all excellent pairings for the Cajun spice fries.

A burger or fish sticks would be perfect with a side of these fries! With so many options, what will you serve your Cajun fries with?
