If you've been scrolling through social media lately, you've likely seen the viral smash burger trend. But as keto eaters, we usually have to toss the bun or deal with messy lettuce wraps that fall apart after one bite. Enter the Deconstructed Smash Burger Casserole—the ultimate solution for your burger cravings without the carb-heavy guilt. This recipe captures that iconic, charred savory beef flavor mixed with a creamy, tangy 'special sauce' that rivals the Golden Arches. By transforming it into a casserole, we retain all the high-fat goodness essential for ketosis while creating a meal prep-friendly dinner that the entire family will love. The healthy fats from the cheddar and mayonnaise keep you satiated for hours, while the protein supports muscle maintenance. It’s comfort food, elevated.

The Masterplan

01

Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with a little butter or avocado oil spray.

02

In a large skillet over medium-high heat, add the ground beef and diced onion. Cook until the beef is browned and the onions are translucent (about 8-10 minutes). Add the minced garlic, salt, and pepper during the last minute of cooking to prevent burning the garlic.

03

While the beef cooks, prepare the 'Secret Smash Sauce'. In a small bowl, whisk together the mayonnaise, sugar-free ketchup, yellow mustard, vinegar, and smoked paprika until smooth.

04

Drain the excess grease from the skillet if desired, though keeping some adds healthy fats. Stir the chopped pickles and HALF of the prepared sauce directly into the cooked meat mixture.

05

Transfer the beef mixture into the prepared baking dish, spreading it out into an even layer.

06

Top the beef generously with the shredded cheddar cheese and crumbled bacon.

07

Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbling golden brown.

08

Remove from the oven and let it sit for 5 minutes. Just before serving, top with fresh shredded lettuce, a drizzle of the remaining sauce, and a sprinkle of sesame seeds to mimic that sesame bun experience.
