• 6 slices thick-cut bacon, cooked until crispy and chopped
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 1 tablespoon Worcestershire sauce
• 1 teaspoon smoked paprika
• 1 teaspoon onion powder
• 1 teaspoon kosher salt and ½ tsp black pepper
• 4 large eggs
• ½ cup heavy whipping cream
• 2 cups shredded sharp cheddar cheese (divided)
• ¼ cup dill pickle slices, chopped
• For Secret Burger Sauce: ½ cup mayo, 2 tbsp sugar-free ketchup, 1 tbsp dill relish, 1 tsp yellow mustard, 1 tsp white vinegar, pinch of garlic powder

Step-by-Step Cooking Instructions

1. Preheat & Prep: Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking casserole dish with cooking spray.
2. Brown the Beef & Aromatics: In a large skillet over medium-high heat, cook ground beef and diced onion, breaking into crumbles, until beef is browned (about 7 minutes). Drain excess grease. Add minced garlic, Worcestershire sauce, paprika, onion powder, salt, and pepper; cook for 1 minute until fragrant.
3. Whisk the Custard: In a medium mixing bowl, whisk eggs, heavy cream, and 1 cup of the shredded cheddar cheese together.
4. Assemble Casserole: Transfer the seasoned beef mixture into the prepared casserole dish, spreading evenly. Pour the egg-cream custard mixture evenly over the beef. Top with remaining 1 cup shredded cheddar, chopped crispy bacon, and chopped dill pickles.
5. Bake to Bubbly Perfection: Bake in preheated oven for 22–25 minutes until the custard is set in the center and the cheese is golden and bubbling.
6. Sauce & Serve: In a small bowl, whisk all Secret Burger Sauce ingredients together. Drizzle generously over the warm casserole or serve in a bowl for dipping. Slice and enjoy!

Chef Sarah’s Golden Tips for Success

• Drain excess beef grease thoroughly before adding the custard to prevent a greasy bake.
• Use sharp cheddar or pepper jack cheese for maximum punchy flavor.
• Dill pickles add an authentic burger acidity that cuts through the rich cheddar and bacon.
• Let the casserole rest for 5 minutes after baking so slices hold together neatly.

Flavor Variations & Dietary Substitutions

Make it spicy by adding sliced pickled jalapeños and pepper jack cheese. For a lighter version, swap ground beef with ground turkey.

Store slices in an airtight container in the refrigerator for up to 5 days. Reheat in the oven or microwave until heated through.
