If you love the kick of a good spice blend and the messy joy of a stacked burger, this copycat Five Guys Cajun Style Burger is for you. It’s bold, buttery, and full of those smoky, peppery Cajun notes that make every bite pop. You’ll get crispy edges on the beef, melty cheese, and a tangy heat that pairs perfectly with classic toppings.

Best of all, it’s easy to make at home with simple ingredients. Fire up the skillet or griddle and let’s make something unforgettable.

Why This Recipe Works

This recipe leans on a fast, high-heat sear to build a crave-worthy crust on the beef. The Cajun seasoning gets toasted in butter, blooming the spices and infusing the burger with deep flavor.

A soft, slightly sweet bun is toasted in the same butter, so every layer tastes rich and cohesive. Double-stacked thin patties keep the burger juicy without feeling heavy, and the cheese melts beautifully for that classic burger-shop finish.

Ingredients

• For the Cajun seasoning mix (makes extra):
  • 2 teaspoons paprika (smoked or sweet)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1 teaspoon cayenne pepper (use 1/2 tsp for milder heat)
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon kosher salt
• For the burgers:
  • 1 lb (450 g) ground beef, 80/20 for best juiciness
  • 2 tablespoons unsalted butter
  • 2 sesame seed burger buns (potato buns or soft brioche work well)
  • 4 slices American cheese (or cheddar, but American melts best)
  • 1 small yellow onion, thinly sliced
  • 1/2 cup sliced dill pickles
  • 1 ripe tomato, sliced
  • Green leaf lettuce
  • Mayonnaise and ketchup, to taste
  • Neutral oil (canola or peanut), for the skillet

Instructions

1. Make the Cajun seasoning. In a small bowl, mix paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, and salt. Stir well. Set aside. You’ll have enough for multiple burgers.
2. Portion the beef. Divide the ground beef into 4 equal balls, about 4 ounces each. Handle lightly to avoid compacting the meat. This helps keep the patties tender.
3. Prep your station. Warm a large cast-iron skillet or flat-top griddle over medium-high heat. Lightly oil the surface. Have a sturdy spatula ready for smashing, plus cheese and buns nearby.
4. Toast the buns in Cajun butter. Melt 2 tablespoons butter in the skillet. Sprinkle in 1 teaspoon Cajun seasoning and let it sizzle for 10–15 seconds to bloom. Place buns cut side down and toast until golden, 45–60 seconds. Remove and set aside.
5. Cook the onions. In the same pan, add the sliced onions with a pinch of salt and a light sprinkle of Cajun seasoning. Cook 2–3 minutes until softened and slightly charred at the edges. Push to the side or transfer to a plate.
6. Smash and sear the patties. Increase heat to high. Place two beef balls on the hot surface.Immediately press each firmly with the spatula until thin, about 1/4 inch. Season tops with a light sprinkle of Cajun seasoning and a pinch of salt.
7. Flip and cheese. Cook 1–2 minutes until edges are dark and lacy. Flip, then top each patty with a slice of American cheese. Cook another 30–60 seconds until cheese melts and the second side is browned. Repeat with remaining patties.
8. Build the burger. Spread mayo on the bottom bun and ketchup on the top bun if you like. Layer lettuce and tomato on the bottom bun. Add two cheesy patties, then pile on onions and pickles. Finish with a light dusting of Cajun seasoning for extra kick. Cap with the top bun.
9. Rest briefly and serve. Let the burger sit 1 minute to settle the juices, then serve hot with fries or chips. For the full Five Guys vibe, wrap it loosely in foil for 2–3 minutes to steam slightly and meld flavors.

How to Store

• Cooked patties: Cool completely, then store in an airtight container in the fridge for up to 3 days. Reheat in a hot skillet for 1–2 minutes per side.
• Cajun seasoning: Keep extra seasoning in a sealed jar in a cool, dark spot for up to 6 months.
• Assembled burgers: Best eaten fresh. If you must store, wrap in foil and refrigerate up to 24 hours, then reheat in a 350°F (175°C) oven for 10–12 minutes. Add fresh lettuce and tomato after reheating.
• Freezing: Freeze raw, seasoned patties between parchment layers in a zip-top bag for up to 3 months. Cook from frozen on a hot skillet, adding 1–2 extra minutes.

Why This is Good for You

Homemade means you control the salt, spice, and fat. Using 80/20 beef delivers flavor, but you can balance it with fresh toppings like lettuce and tomato for fiber and crunch.

The spice blend brings antioxidants from herbs and spices like paprika and thyme. You also skip unnecessary additives often found in fast food, and you can moderate portion sizes to fit your needs.

Common Mistakes to Avoid

• Overworking the beef: Packing the meat too tightly makes patties dense and tough. Form loose balls and smash once.
• Cold pan: If the pan isn’t ripping hot, you won’t get that crispy crust.Preheat until a drop of water sizzles instantly.
• Too much seasoning on the meat: Cajun seasoning can be salty and spicy. Use a light sprinkle on each side and finish with a dusting at the end.
• Skipping the butter toast: The bun toasted in Cajun butter ties the whole burger together. Don’t skip it.
• Stacking wet toppings under the patty: Place lettuce and tomato on the bun first to protect it from getting soggy.

Alternatives

• Lean beef or turkey: Use 90/10 beef or ground turkey and add 1 tablespoon mayo per pound for moisture. Cook gently to avoid drying out.
• Plant-based option: Smash-style plant patties work well. Season with Cajun blend and cook in oil or vegan butter for crisp edges.
• Cheese swap: Pepper jack for extra heat, or provolone for a milder melt.
• Bun choices: Potato, brioche, or sesame buns are great. For gluten-free, use a sturdy GF bun or lettuce wrap.
• Heat control: Reduce cayenne by half for mild, or add a few dashes of hot sauce to the mayo for extra kick.
• Add-ons: Crispy bacon, grilled mushrooms, or jalapeños fit the Cajun profile nicely.

FAQ

Can I cook these on a regular nonstick pan?

Yes.

A cast-iron skillet or griddle is best for crust, but a nonstick pan works. Preheat thoroughly and avoid overcrowding so the patties sear, not steam.

What fat percentage is best for smash burgers?

80/20 is the sweet spot for juiciness and flavor. Leaner blends can taste dry, while fattier blends may shrink too much and get greasy.

How do I keep the patties from sticking when smashing?

Use a well-oiled, very hot surface and a sturdy spatula.

You can place a small square of parchment on the beef, then press, and peel it off immediately.

Is American cheese necessary?

Not necessary, but it melts into every nook of a smash patty. If you prefer cheddar, slice it thin or use deli-sliced for better melt.

How spicy is this Cajun mix?

Moderately spicy. For a gentler heat, cut the cayenne in half.

For extra heat, add a pinch more cayenne or a dash of hot sauce to the mayo.

Can I make the patties thicker?

You can, but you’ll lose the signature crispy edges. If making thicker patties, lower the heat slightly and cook longer to avoid a raw center.

What sides go best with a Cajun burger?

Seasoned fries, sweet potato fries, or onion rings are great. A simple coleslaw or corn salad balances the heat with something cool and crunchy.

Can I grill these instead?

Yes, but smashing on open grates is tricky.

Use a flat-top griddle insert or a cast-iron skillet on the grill to get that proper sear.
