Step by Step Instructions
- Brown the Beef and Onion:
- Cook the ground beef and diced onion over medium heat until beef is fully browned and onions are soft and translucent This can take about 8 to 10 minutes Use a wooden spoon to break beef into small crumbles for even texture Drain off as much fat as possible so the casserole is not greasy
- Season and Build the Flavor:
- Add the Worcestershire sauce garlic powder a pinch of salt and pepper Stir well and let cook for a further two minutes to allow flavors to develop Stirring frequently ensures nothing sticks to the pan and everything is seasoned evenly
- Layer the Casserole Base:
- Transfer the beef mixture into a nine by thirteen inch baking dish making sure to smooth it into an even layer Sprinkle the chopped dill pickle chips over the beef pressing gently so they nestle evenly throughout every bite
- Mix the Creamy Sauce Topping:
- In a large bowl whisk together the eggs heavy cream mayonnaise mustard ketchup onion powder and paprika Whisk until completely smooth and uniform It should look a bit like burger sauce but thinner This is what creates that signature soft layer over the beef
- Pour and Cheese:
- Evenly pour the egg sauce mixture over the beef and pickles in the baking dish Use a spatula to encourage it into every corner Sprinkle all of the shredded cheddar cheese over the top for maximum melt and flavor
- Bake Until Bubbling:
- Place the casserole uncovered into your preheated oven Bake for twenty five to thirty minutes until the cheese is melted golden and bubbling all over The casserole should feel set and slightly puffed up in the center
- Cool and Top with Lettuce:
- Let the casserole rest for at least five minutes after removing from the oven This helps slices hold together Sprinkle a generous layer of freshly shredded iceberg lettuce over the top just before serving for that signature crunch and freshness

I always look forward to biting into the tangy crisp pickles in each slice They make a huge difference and remind me of special Big Mac runs as a kid My kids now argue about who gets the last pickle loaded serving
Storage Tips
Let the casserole cool completely before covering with foil or an airtight lid Store in the fridge for up to three days The lettuce topping is best added just before serving since it gets soggy in the fridge Reheat individual slices uncovered for best texture or cover the whole dish at three hundred fifty degrees Fahrenheit until warmed through
Ingredient Substitutions
