  • 200g96% extra-lean ground beef (or extra-lean minced rump steak)
  • 1Light whole-wheat burger bun (or whole-wheat sandwich thin)
  • 1 sliceReduced-fat or light cheddar cheese
  • 100gRaw sweet potato, cut into thin fries
  • 30gYellow onion, thinly sliced
  • 3-4 slicesDill pickles
  • as neededZero-calorie cooking spray
  • to tasteSalt, black pepper, garlic powder, and smoked paprika

  • 30gPlain non-fat (0%) Greek yogurt
  • 1 tspSugar-free ketchup
  • 1 tspYellow mustard
  • 1 tbspPickle juice (straight from the jar)

👨‍🍳Method

1

Bake the Fries

15-20 min

Preheat your oven to 200°C (400°F) or an air fryer to 190°C (375°F). Toss the sweet potato fries with a generous spray of zero-calorie cooking spray, salt, garlic powder, and smoked paprika. Spread them in a single layer and bake for 15-20 minutes (or air fry for 10-12 minutes) until golden and crispy.

💡Don't overcrowd the tray — a single layer is the secret to crispy fries instead of steamed ones.
2

Make the Lean Sauce

1 min

In a small bowl, whisk together the non-fat Greek yogurt, sugar-free ketchup, mustard, and pickle juice. This creates an authentic, tangy burger sauce for a fraction of the calories of mayo-based sauces. Set aside.

3

Caramelize the Onions (Oil-Free)

10 min

Heat a non-stick skillet over medium-low heat with a quick spray of zero-calorie cooking spray. Add the sliced onions and a pinch of salt. Cook slowly. Whenever they start to stick or dry out, add a small splash of water instead of oil. Continue this process for about 10 minutes until they are soft, brown, and naturally caramelized.

💡Patience is everything — low and slow with water splashes creates the same deep caramelization as butter, with zero added fat.
4

Cook the Patty

6-8 min

Form the extra-lean ground beef into a wide, flat patty (it will shrink slightly as it cooks). Season generously with salt and pepper. Turn the skillet up to medium-high heat. Cook the patty for 3-4 minutes per side. In the last minute of cooking, place the slice of light cheddar on top of the patty and cover the pan with a lid for 30 seconds so the cheese melts perfectly.

💡Make the patty wider than the bun — it shrinks about 20% as it cooks and will fit perfectly.
5

Assemble

2 min

Toast your light whole-wheat bun. Spread the lean burger sauce on both the top and bottom buns. Layer the bottom bun with the pickle slices, place the cheesy beef patty on top, and pile on the caramelized onions. Close the burger and serve immediately with your crispy sweet potato fries.
