What Makes This Special

Five Guys fries are famous for a reason: they taste like real potatoes, and the seasoning is balanced—spicy, garlicky, and a little smoky. This copycat version captures those flavors with a simple Cajun blend and a two-step cook for extra crispness.

You get control over heat level, salt, and oil, so the fries are tailored to your taste. Best of all, they still deliver that iconic fast-casual vibe at home.

Shopping List

• Russet potatoes (3–4 large; about 2 pounds)
• Peanut oil or canola oil (for frying or roasting)
• Kosher salt
• Cajun seasoning blend (or make your own with the spices below)
• Optional: White vinegar (for soaking potatoes)
• Garlic powder
• Onion powder
• Paprika (use smoked for extra depth)
• Cayenne pepper
• Dried oregano
• Dried thyme
• Black pepper
• Sugar (a pinch, optional, to balance the spice)

How to Make It

1. Mix the Cajun seasoning. In a small bowl, combine 1 tablespoon paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1/2 teaspoon cayenne (more if you like heat), 1/2 teaspoon dried oregano, 1/2 teaspoon dried thyme, 1/2 teaspoon black pepper, 1 teaspoon kosher salt, and a pinch of sugar. Set aside. If using a store-bought Cajun blend, taste it first and adjust salt and cayenne to preference.
2. Cut the potatoes. Scrub russet potatoes well. Leave the skins on for that Five Guys texture. Slice into 1/4- to 1/2-inch thick fries. Try to keep them uniform for even cooking.
3. Soak to remove starch. Place cut fries in a large bowl of cold water with 1 tablespoon white vinegar. Soak 30–45 minutes. This helps the fries crisp up and prevents sticking.
4. Rinse and dry thoroughly. Drain the fries, rinse under cold water, then spread on clean towels and pat very dry. Moisture is the enemy of crisp fries.
5. Choose your cooking method. You can deep fry, air fry, or oven bake. Deep frying gives the most authentic texture, but the other methods still deliver great results.
6. Deep fry method—first fry (blanch): Heat peanut oil to 325°F (165°C) in a heavy pot. Fry in batches for 3–4 minutes until the fries look pale and flexible, not browned.Drain on a rack or paper towels. Let rest 10 minutes.
7. Deep fry method—second fry: Increase oil to 375°F (190°C). Fry the blanched potatoes in batches for 2–3 minutes until golden and crisp. Move quickly to the next step while they’re hot.
8. Air fryer method: Toss dried fries with 1–2 tablespoons oil. Air fry at 375°F (190°C) for 12–15 minutes, shaking the basket every 4–5 minutes, until crisp and golden. For extra crunch, let them rest 5 minutes, then air fry 2–3 minutes more.
9. Oven method: Toss fries with 2–3 tablespoons oil and 1 teaspoon salt. Spread in a single layer on preheated baking sheets (425°F/220°C) lined with parchment. Bake 25–35 minutes, flipping halfway, until browned and crisp at the edges.
10. Season immediately. While the fries are hot, move them to a bowl. Sprinkle generously with the Cajun seasoning and an extra pinch of salt if needed.Toss to coat evenly. Start with 1–2 teaspoons seasoning per serving and adjust to taste.
11. Serve hot. These are best right away. Add more seasoning at the table if you like them bolder.Great with ketchup, chipotle mayo, or ranch.

Storage Instructions

Fries are best fresh, but you can store leftovers. Cool completely, then refrigerate in an airtight container for up to 3 days. Reheat in an air fryer at 375°F for 5–7 minutes or in a hot oven (425°F) for 10–12 minutes.

Avoid microwaving—it makes them soft. If freezing, freeze in a single layer first, then transfer to a bag; reheat from frozen in an air fryer or oven until crisp.

Why This is Good for You

• Real ingredients: You control the oil, salt, and spices—no mystery additives.
• Spice benefits: Paprika, garlic, and thyme bring antioxidants and flavor without extra calories.
• Potatoes are satisfying: They’re a good source of potassium and fiber (especially with skins on), which helps you feel full.
• Flexible cooking: Air-frying or baking reduces oil while keeping the crunch.

Common Mistakes to Avoid

• Skipping the soak: Not soaking leads to gummy, less crispy fries.
• Under-drying: Water on the potatoes makes oil splatter and soft fries.
• Overcrowding the pan: Too many fries drop the oil temperature and make them soggy. Cook in batches.
• Seasoning too early: Add Cajun seasoning after cooking so it sticks to the hot fries and doesn’t burn.
• Using the wrong potato: Russets are best. Waxy potatoes won’t crisp the same.

Variations You Can Try

• Extra smoky: Use smoked paprika and add a pinch of chipotle powder.
• Butter toss: Melt 1 tablespoon butter and toss with the hot fries before seasoning for a richer flavor.
• Lemon kick: Finish with a squeeze of lemon or a sprinkle of lemon zest to brighten the spices.
• Heat control: Reduce cayenne for mild fries, or add crushed red pepper for extra heat.
• Sweet potato version: Swap in sweet potatoes; bake or air fry for best texture, and add a touch more salt to balance sweetness.
• Garlic lovers: Toss hot fries with finely minced fresh garlic and parsley plus the Cajun seasoning.

FAQ

Do I have to use peanut oil?

No. Peanut oil is traditional for a clean, high-heat fry, but canola, corn, or vegetable oil work too. Just choose a neutral oil with a high smoke point.

Can I make the seasoning ahead of time?

Yes.

Mix a larger batch and store it in an airtight jar for up to 6 months. Keep it in a cool, dark place to preserve the flavors.

Why are my fries still soft?

They may have too much surface moisture, the oil may not be hot enough, or the pan was overcrowded. Dry thoroughly, keep oil at the right temperature, and cook in batches.

What’s the closest texture to Five Guys at home?

Double frying in peanut oil gives the closest texture—creamy inside and very crisp outside.

Air-frying comes in second and is easier for everyday cooking.

How spicy is this?

Moderate heat as written. Reduce cayenne for mild fries, or increase it for a fiery version. You can also add more seasoning after tasting.

Can I skip the vinegar in the soak?

Yes, it’s optional.

Vinegar helps reinforce the potato structure for better crispness, but plain water soaking still works well.

What’s the best cut size?

About 1/4 to 1/2 inch thick. Thinner fries crisp faster but can overbrown; thicker fries need a proper blanch to cook through.
