01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish with cooking spray or butter.
02 - In a large skillet over medium heat, cook the chopped bacon until crisp. Remove bacon with a slotted spoon and set aside on paper towels, leaving 1-2 tablespoons of bacon fat in the pan.
03 - Add ground beef to the skillet with the reserved bacon fat. Cook over medium-high heat, breaking up with a spatula, until browned. Drain excess fat if needed.
04 - Add the diced onion and minced garlic to the beef. Sauté for 2-3 minutes, stirring occasionally, until the onion is softened and fragrant.
05 - Stir in diced tomatoes, chopped pickles, sugar-free ketchup, yellow mustard, Worcestershire sauce, smoked paprika, salt, and black pepper. Cook for 2-3 minutes to blend flavors, then remove from heat.
06 - In a separate medium bowl, whisk together the softened cream cheese and heavy cream until completely smooth and no lumps remain.
07 - Spread the beef mixture evenly in the prepared baking dish. Pour the cream cheese mixture over the top and use a spatula to gently swirl it into the beef layer.
08 - Sprinkle the shredded cheddar cheese evenly over the casserole, then distribute the cooked bacon pieces on top.
09 - Bake for 20-25 minutes, until the cheese is bubbly and beginning to turn golden brown.
10 - Let the casserole rest for 5 minutes before serving. Garnish with sliced green onions or extra pickles if desired.
