Why You’ll Love This Five Guys Burger & Cajun Fries Copycat
- Authentic flavour, no queue: We’re using a simple smash technique and a specific spice blend to replicate that iconic, crusty patty and perfectly seasoned fries without leaving the house.
- Complete control over quality: You choose the beef, the bun, and the toppings. I always use a good, high-quality beef mince with a decent fat content for the juiciest results.
- Build-your-own bar potential: The real magic of the original is the sheer number of toppings. This recipe encourages a big spread of fresh ingredients so everyone can assemble their perfect burger.
- Simple, pantry-spice fries: The Cajun fries rely on a blend of common spices you likely already have. I stumbled upon this combination by accident, and it’s been a hit ever since.
- Perfect for a satisfying meal: This isn’t a quick snack; it’s a proper, hearty meal that feels like a real occasion. The process of smashing the patties and watching them sizzle is deeply satisfying.
Ingredients You’ll Need
- For the Cajun Fries:
- 4 large floury potatoes (like Maris Piper or King Edward), scrubbed and cut into 1cm thick batons (about 800g)
- 3 tablespoons vegetable or sunflower oil
- 1½ teaspoons smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon cayenne pepper (adjust to taste)
- 1 teaspoon dried oregano
- 1 teaspoon fine sea salt
- ½ teaspoon freshly ground black pepper
- For the Burgers:
- 800g beef mince (at least 20% fat, like chuck or brisket blend)
- 4 soft burger buns
- 4 slices of American cheese (or your favourite melting cheese)
- Vegetable oil, for the pan
- Salt and freshly ground black pepper, for the patties
- For the Toppings (your choice): Lettuce, tomato, sliced onion, pickles, jalapeños, ketchup, mustard, mayonnaise, and grilled mushrooms.
Tip: For the fries, soaking the cut potatoes in cold water for at least 30 minutes removes excess starch. This is the key to getting them properly crisp rather than soggy. Pat them bone-dry with a clean tea towel before you start cooking.
How to Make Five Guys Burger & Cajun Fries Copycat
- Prepare the fries: After soaking and drying your potato batons, toss them in a large bowl with the vegetable oil. In a small bowl, mix the smoked paprika, garlic powder, onion powder, cayenne, oregano, salt, and pepper. Sprinkle this spice mix over the oiled potatoes and toss well until every baton is evenly coated. You’ll see a beautiful, deep red-orange colour developing on the potatoes.
- Cook the fries: Preheat your oven to 220°C (200°C fan). Spread the seasoned fries in a single layer on a large baking tray. Don’t overcrowd them – they need space to crisp up. Bake for 20-25 minutes, turning them halfway through. They are ready when they are a deep golden brown, feel firm to the touch, and you can hear a slight crunch when you nudge them with a spatula.
- Shape the patties: While the fries are baking, divide your beef mince into 4 equal portions, about 200g each. Roll each portion into a ball. Do not season the meat yet. You’ll feel the soft, cool texture of the mince as you roll it.
- Smash and cook the patties: Place a large, heavy-bottomed frying pan or flat-top griddle over high heat and add a thin film of vegetable oil. Once the oil is shimmering and almost smoking, carefully place a beef ball in the pan. Using a sturdy spatula, immediately smash the ball down into a flat, thin patty, about 1cm thick. You should hear a loud, satisfying sizzle as it hits the pan. Season generously with salt and pepper. Cook for 2-3 minutes without moving it. You’ll see the edges turning a deep brown and the patty will look set around the edges.
- Flip and add cheese: Flip the patty using your spatula, scraping up all the delicious, browned crust from the pan. The cooked side should be a rich, deep mahogany colour with crispy, lacy edges. Place a slice of cheese on top immediately. Cook for another 1-2 minutes, until the cheese is melted and the patty is cooked through. You’ll see the cheese starting to bubble and soften around the edges.
- Toast the buns: While the patties are resting (briefly), split your burger buns and place them cut-side down in the residual fat in the pan. Toast for about 30-60 seconds, until they are golden brown and smell wonderfully nutty and warm.
- Assemble the burgers: On the bottom half of your toasted bun, place your chosen toppings: lettuce, tomato, onion, pickles. Place the cheesy patty on top, then add your sauces and any other extras. Cap with the top bun. The stack should be tall, messy, and utterly inviting. Serve immediately with the hot Cajun fries.
Tips From My Kitchen
- Use high-fat beef mince for flavour: The secret to a juicy, flavour-packed patty like the ones from the famous chain is the fat content. I always use mince that is at least 20% fat. As it renders during the high-heat cooking, it bastes the patty and creates that incredible, crispy crust. Leaner mince will result in a dry, less flavourful burger.
- Don’t season the mince before shaping: Salt draws moisture out of the meat. If you mix salt into your mince before forming the patties, it will make the texture dense and tough. Always season generously with salt and pepper only after you have smashed the patty onto the hot cooking surface. This allows the salt to create a beautiful, salty crust on the outside without compromising the meat’s internal moisture.
- Get the pan screaming hot for the smash: The iconic, lacy, crispy crust on the patty comes from immediate, intense heat. Your pan or griddle must be hot enough that a drop of water dances and evaporates instantly. If the pan isn’t hot enough, the patty will steam rather than sear, and you’ll lose that crucial texture and flavour. I used to struggle with this dish until I discovered this technique – it makes all the difference.
- Soak and dry your potatoes properly: For the crispiest fries, this step is non-negotiable. Soaking the cut potatoes in cold water for at least 30 minutes (or up to overnight in the fridge) removes surface starch, which is what makes fries clump together and become soft. After soaking, you must dry them absolutely thoroughly. Any remaining moisture will turn to steam in the oven and prevent them from becoming crisp.
- Make your own Cajun seasoning blend: Pre-made Cajun seasonings can vary wildly in salt content and heat. By mixing your own, you have total control. The blend I’ve provided is a great starting point, but feel free to adjust the cayenne to your preferred spice level. A pinch of dried thyme or a touch of white pepper can also add lovely depth.
Equipment You’ll Need
- Large, heavy-bottomed frying pan or flat-top griddle (cast iron is brilliant)
- Sharp knife and cutting board
- Large mixing bowls
- Sturdy metal spatula (for smashing the patties)
- Baking tray for the fries
- Clean tea towel or kitchen paper for drying potatoes
Common Mistakes to Avoid
- Overcrowding the pan: When you add too many patties or too many fries to the pan or tray at once, the temperature drops significantly. This causes the food to steam instead of searing or crisping. Always cook in batches, giving each piece of food enough space to allow the heat to circulate and create that golden-brown crust.
- Wrong temperature: For the patties, you need high heat for a sear. For the fries, you need a hot oven (220°C). If your oven is too cool, the fries will absorb the oil and become greasy and limp. If your pan is not hot enough for the burgers, you won’t get the Maillard reaction that creates that deep, savoury flavour.
- Skipping the rest time: While you don’t need to rest the patties for a long time like a steak, letting them sit for just one minute off the heat before assembling is important. This brief rest allows the juices to redistribute slightly throughout the meat, so when you bite into the burger, they stay in the patty rather than running out all over your plate.
What to Serve With Five Guys Burger & Cajun Fries Copycat
- A simple, crisp side salad with a tangy vinaigrette to cut through the richness.
- Extra pickles and jalapeños on the side for those who love a bit of heat and acidity.
- For a fun twist, serve alongside a portion of our Outback Steakhouse Blooming Onion Copycat for a fantastic sharing starter.
- A cold, non-alcoholic drink like a root beer or a sparkling lemonade is the perfect accompaniment.
- If you’re after a different kind of potato side, our Panda Express Fried Rice Copycat makes for an unexpectedly delicious and satisfying accompaniment to a burger.
Frequently Asked Questions
Can I use a different type of potato for the fries?
Yes, you can. Floury potatoes like Maris Piper or King Edward are ideal for a fluffy interior and crispy exterior. Waxy potatoes like new potatoes or red potatoes hold their shape better but won’t achieve the same light, fluffy texture inside. If using waxy potatoes, you’ll get a firmer, denser fry, which is still tasty but not quite the same as the original.
How do I get my burger patties to stay together?
The key is not to overwork the meat. When you form the balls and then smash them, you are creating a thin patty that clings together naturally from the high heat and the protein binding. Do not add eggs or breadcrumbs. The high fat content and the intense heat of the pan will create a secure, cohesive crust that holds everything together perfectly.
Can I make the Cajun fries in an air fryer?
Absolutely. An air fryer is excellent for this recipe. Prepare the potatoes in the same way, tossing them in oil and the spice mix. Preheat your air fryer to 200°C and cook the fries in a single layer for 12-15 minutes, shaking the basket halfway through. You will achieve a very crisp exterior with a fluffy interior, often with even less oil than baking.
What is the best way to toast the buns?
Toasting the buns in the same pan you cooked the patties in is the best method. After you’ve removed the patties, there will be a thin layer of rendered beef fat and delicious browned bits in the pan. Place the buns cut-side down in this hot fat for 30-60 seconds. They will absorb that savoury flavour and get beautifully golden and crisp on the inside while staying soft on the outside.
Can I prepare any of this in advance?
You can do some prep work ahead. The dry spice mix for the fries can be made and stored in an airtight jar for weeks. You can also shape your beef into balls and keep them covered in the fridge for up to 24 hours. The potato batons can be cut and soaked in water in the fridge overnight, but you should dry and season them just before cooking for the best texture.
