Cheeseburgers with Jalapeño Sauce and Sweet Potato Fries

"Prepare to get blown away. This could be the very best juicy cheeseburger, glossed with melted cheese, slathered with a sweet and spicy jalapeño sauce, topped with caramelized onions and sandwiched between squishy buns. Served with crispy sweet potato fries. These are perfectly spiced and juicy 5′ beef burgers, seared on the outside, yet soft in the middle. I like to add thinly shaved onions to my skillet and cook the burgers in salted butter. The result is a more flavorful and juicier patty. Then, I usually toast the buns in the same skillet wherein I cooked the burgers. They will pick up the rendered fat and browned bits. Overall, more flavor. The sauce is a heavenly combination and a perfect four-way intersection of sweetness, acid, creaminess, and heat. Every flavor balances the other. It’s delicious on burgers, salads or fries. And the perfect fit with roasted vegetables as well. You can save the recipe for whenever you need a real garlic hit! Now for these sweet potato fries… They’re simply the best thing to serve with a burger, spiced and sweet all at once. I like to cut them thinly and skinny, then toss with a mix of cayenne pepper, garlic and smoky paprika. Roast in the oven until crisp on the outside, but still soft in the center. These are addictive. You might just double the recipe. Some for the burger and some to snack on. Just a thought… I hope you make these! You’ll be so happy."

  • Sea salt and freshly ground black pepper t otaste
  • 1 large onion, sliced thinly
  • 2 tablespoons salted butter
  • 4 tomato slices
  • 4 large iceberg lettuce, leaves, torn into pieces
  • 4 slices cheddar

jalapeño sauce


  • 4 tablespoons mayo
  • 1 teaspoon ketchup
  • 2 tablespoons whisky
  • 1 teaspoon worcestershire sauce
  • 1 tablespoon jalapeños, finely chopped
  • 1 teaspoon mustard
  • 1/2 teaspoon smoked paprika
  • 1 teaspoon honey
  • 2 cloves garlic, finely minced
  • 1/2 teaspoon onion powder

sweet potato fries


  • 2 medium sweet potatoes, peeled and cut into 1 cm fries
  • 3 tablespoons olive oil
  • 1 teaspoon thyme
  • 1 teaspoon cayenne pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 2 tablespoons potato starch
  • Fine sea salt to taste


  • Step 1

    To make the fries. Preheat the oven to 220C or 425F. Place the sweet potatoes in a large bowl filled with ice water, let sit for 5 minutes. Drain and lay them between two clean kitchen towels. Massage a little, they should be as dry as possible. Place in a dry bowl, toss with thyme, cayenne pepper, garlic powder, smoked paprika and potato starch, season with salt. Spread the fries in an even layer on a baking sheet. Do not overcrowd the pan, if needed, divide the fries between 2 baking sheets. Transfer to the oven and bake for 15-20 minutes, flip and bake for 10-15 minutes more. You want the sweet potatoes to be tender, yet crisp.

  • Step 2

    Combine all the ingredients for the sauce in a small bowl.

  • Step 3

    Combine beef with heavy cream, onion powder, salt and pepper. Divide into 4 equal pieces. Using both hands, work meat into smooth balls, compacting very lightly. Press down to flatten each ball into a 2 cm thick patty. I highly recommend using a round biscuit-cutter to help forming uniformly shaped patties. It makes a huge difference. Heat a large, heavy-bottomed skillet over high heat. Melt the butter, add the patties and thinly sliced onion. Cook, without any touching, until edges are browned and you can see juices pooling in the center of patties, about 3 minutes. Then flip them over and place a slice of cheese on each burger. Cook for 2 minutes more. Never cook the burgers all the way through. The best doneness, is medium. The burger should have deeply caramelized crust on both sides, but you’ll still see juice oozing out from the mid-section. The skillet should be very hot to achieve this. Transfer burgers to a plate. Now place the buns into the same skillet, toast the buns, side down, until golden and crisp around the edges.

  • Step 4

    Start to build your burger. Spread a tablespoon of the sauce on bottom halves of the buns. Place a slice of tomato, lettuce, burgers and caramelized onions. Top with a tablespoon of sauce, close with the top bun, and serve with sweet potato fries and some extra sauce. Enjoy!
