1-First: start by gently mixing the ground beef, egg yolk, shredded Parmesan cheese, fine sourdough breadcrumbs, and seasonings in a medium bowl. Avoid overmixing to keep the burgers tender; it’s a tip that makes all the difference, just like when I first learned it from a family cookout.

2-Next: divide the mixture into three equal portions and shape each into a patty, making a small indent in the center to help them cook evenly. Preheat your grill or cast iron skillet over medium heat, then cook the patties for 4-6 minutes per side until they’re nicely browned.

Adding Finishing Touches: During the last 2 minutes, add the sharp cheddar cheese slices on top to melt perfectly over the patties. Meanwhile, grill the buttered buns buttered side down for about one minute to get that golden crisp. In a small bowl, combine the mayonnaise, ketchup, molasses or maple syrup, and Cajun seasoning to make the sauce that ties it all together.

Finally, assemble your burgers by placing the cheese-topped patties on the buns, then layering on the lettuce, sliced red onion, and that homemade Cajun sauce. The result is a smoky, spicy delight that’s perfect for casual meals, with the sharp cheddar adding a creamy contrast.
