For the Burger Patty:
- 2–4 oz ground beef
- Salt and black pepper, to taste
- 1 tbsp mustard (for searing)

Step-by-Step Instructions
Step 1: Make the Sweet Potato Buns
- Shred or grate the raw sweet potato finely using a box grater or food processor.
- In a bowl, mix the shredded sweet potato thoroughly with the large egg.
- Transfer the mixture into a preheated waffle maker and cook for a few minutes until crispy and cooked through. Remove and set aside.
Step 2: Prepare the Burger Patty
- Season your ground beef with salt and black pepper, then shape it into a thin patty.
- Spread mustard on both sides of the raw patty.
- Heat a skillet over medium-high heat and fry the patty for a few minutes on each side until nicely browned and cooked to your liking.
Step 3: Melt the Cheese
- Place your slice of cheddar or American cheese directly on top of the hot burger patty.
- Reduce the heat to low, cover the skillet with a lid, and let it steam for 1 minute until the cheese is gloriously melted.
Step 4: Mix the Homemade Spread
- In a small bowl, whisk together the mayonnaise, sugar-free ketchup, and dill relish until smooth and well combined.
Step 5: Assemble and Serve
- Place your cheesy beef patty onto your sweet potato waffle buns.
- Top with the sweet, caramelized grilled onion and a generous dollop of your homemade burger spread.
- Serve immediately and enjoy your healthy, homemade style In-N-Out masterpiece!
