Ingredients
For the Sauce
Instructions
-
Heat a cast iron skillet over medium heat and add the ground beef. Cook until browned, breaking it up as it cooks.
-
Add the diced onion and garlic. Continue cooking until the onion softens and becomes translucent. Mix until combined. Season with salt and pepper. Stir in the Worcestershire sauce, liquid smoke, and paprika. Stir and cook for another minute to combine the flavors.
-
Reduce the heat to low and add the mayo, sour cream, ketchup, mustard, and pickle juice. Stir until everything is well combined and the mixture becomes thick and creamy.
-
Fold in the diced pickles, crumbled bacon, and half of the red onion. Mix once again.
-
Add the mozzarella and cheddar cheese to the skillet and stir until evenly mixed.
-
Smooth the mixture out in the pan, then top with the remaining cheddar and a small amount of mozzarella. Do not press the cheese down.
-
Transfer the skillet to a preheated 375°F (190°C) oven and bake for 20–25 minutes, or until the cheese is melted and bubbling.
-
Remove from the oven and let it rest for a few minutes. Top with pickle slices and drizzle the prepared sauce over the top before serving.

To Make the Sauce
In a small bowl, make the sauce by combining the mayo, ketchup, mustard, pickle juice, garlic powder, onion powder, and water. Mix until smooth and set aside. I transfer mine to a squeeze bottle so I can drizzle it over the top, but a spoon works fine as well.

Note
For the best melt, use a combination of mozzarella and freshly shredded cheddar cheese. Pre-shredded cheese can result in a slightly grainy texture.
• Add the sauce drizzle after baking for the best flavor and presentation. This keeps it glossy and prevents it from soaking into the cheese.
• A small dash (¼ tsp) of liquid smoke can be added to the sauce or beef mixture for a subtle flame-grilled flavor.
• Let the casserole rest for 3–5 minutes before serving. This helps it set slightly and makes for a better cheese pull.
• Adjust the tang by adding a little more pickle juice or mustard if desired.
• This recipe works best in a cast iron skillet, but any oven-safe pan can be used if needed.
