These oven-baked fries are coated in a bold blend of Cajun spices including smoked paprika, garlic, and cayenne pepper, delivering a crispy and flavorful bite. Paired with a creamy and tangy mayonnaise dip infused with hot sauce and lemon juice, this dish offers a perfect balance of heat and creaminess. Ideal as a side or snack, the fries are baked to a golden crisp with simple preparation steps that highlight natural flavors. Adjust the spice levels to suit your taste, and experiment by swapping russet potatoes for sweet potatoes for a different twist.
The first time I made these Cajun spiced fries was during a lazy Sunday afternoon when my roommate and I were craving something spicy enough to wake us up. We ended up eating the entire batch straight from the baking sheet, standing in the kitchen, burning our fingers just to get to the next crispy one. The spicy mayo was an afterthought, but it turned out to be the element that made these fries completely addictive.
Last summer I made these for a backyard barbecue and watched my friend who claims she hates spicy food keep going back for more. She said the heat was just right, that kind that makes your lips tingle without overwhelming everything else. Now whenever I host, someone asks if those spicy fries are making an appearance.
Ingredients
- 4 large russet potatoes: These starchy potatoes are the secret to getting that fluffy interior while still developing a crispy exterior, and peeling is totally up to your preference
- 2 tbsp olive oil: This helps the seasoning stick and promotes even browning, but dont be tempted to add more or the fries might get soggy
- 1 tsp smoked paprika: This gives the fries that gorgeous reddish hue and adds a subtle smoky depth that regular paprika just cant match
- 1 tsp garlic powder and 1 tsp onion powder: These two work together to create that savory base flavor that makes Cajun seasoning so addictive
- 1 tsp dried oregano and 1 tsp dried thyme: These herbs add earthy undertones that balance out the heat and give the seasoning its authentic character
- ½ tsp cayenne pepper: This brings the fire, so start with less if you are sensitive to heat, but the beauty of Cajun spice is that warm kick
- ½ cup mayonnaise: The creamy base for your dipping sauce, and real mayo makes a huge difference here over the lighter stuff
- 1 tbsp hot sauce: Sriracha gives a slightly sweet heat, while Louisiana style hot sauce brings more vinegar tang, choose what you love
Instructions
- Get your oven ready and prep the potatoes:
- Preheat your oven to 220°C and line a large baking sheet with parchment paper, then soak your cut potatoes in cold water for 20 to 30 minutes to remove excess starch for maximum crispiness, draining and patting them completely dry with a kitchen towel
- Coat the fries with all that gorgeous seasoning:
- In a large bowl, toss the dried fries with olive oil and all the spices until every piece is evenly coated in that reddish orange mixture
- Bake them to golden perfection:
- Spread the fries in a single layer on your prepared baking sheet and bake for 30 to 35 minutes, flipping halfway through, until they are golden brown with crispy edges
- Whisk up the spicy mayo while the oven does its work:
- Mix the mayonnaise, hot sauce, lemon juice, garlic powder, smoked paprika, and salt in a small bowl until smooth, then taste and adjust the heat or seasoning to your liking
- Bring it all together:
- Serve those hot, crispy Cajun fries immediately with the spicy mayo on the side for dipping, and watch them disappear
These fries have become my go to when I need something comforting but still exciting enough to feel like a treat. There is something satisfying about making restaurant style food in your own kitchen, especially when it is this simple.
Getting That Perfect Crunch
The soaking step might seem annoying, but it is the difference between okay fries and amazing ones. I have skipped it before when I was rushed, and I could immediately tell the difference in texture. That extra 20 minutes is worth every second.
Customizing Your Heat Level
Not everyone loves spice the way I do, and that is completely fine. You can easily dial back the cayenne to a quarter teaspoon and still get all that Cajun flavor without the intense heat. On the flip side, if you want to really challenge yourself, bump it up to a full teaspoon and maybe add some extra hot sauce to the mayo.
Serving Ideas and Pairings
These fries are incredibly versatile and can hold their own alongside so many main dishes. They are particularly fantastic with burgers, fried chicken, or even as part of a bigger appetizer spread. I have also been known to eat them as a meal on their own when I am feeling particularly indulgent.
- Try crumbling some cooked bacon over the top for an extra savory crunch
- Fresh chopped parsley or green onions add a nice fresh contrast to all the rich spices
- A squeeze of fresh lime right before serving brightens everything up beautifully
Hope these Cajun spiced fries find their way into your regular rotation. They are the kind of recipe that makes people ask when you are making them again.
