Step-by-Step Instructions

- Set your oven to 350 degrees Fahrenheit and allow it to warm up fully while you prep other ingredients so the casserole bakes evenly
- Cook the Beef and Onion:
- Place the ground beef and diced onion in a large skillet over medium heat Cook until the beef is deeply browned and the onion turns translucent about eight to ten minutes Stir frequently and break up clumps so the beef cooks evenly Drain off any fat after cooking to keep the casserole from getting greasy
- Add Seasonings:
- Stir in Worcestershire sauce garlic powder salt and pepper with the cooked beef and onion Let it cook together for two more minutes to bring out the savory base Remove from heat
- Layer into the Dish:
- Spread the seasoned beef mixture into a nine by thirteen inch baking dish Use a spoon to smooth it into an even layer Sprinkle chopped dill pickle chips across the surface paying attention to get them scattered everywhere for even tangy bites
- Mix Eggs and Sauce:
- Whisk eggs heavy cream mayonnaise mustard ketchup onion powder and paprika in a bowl until fully blended Pour this creamy mixture evenly over the beef and pickles using a spatula to cover every corner
- Add Cheese:
- Sprinkle shredded cheddar cheese over the top of the egg layer Distribute it in an even layer for perfect golden bubbling
- Bake:
- Slide the baking dish into your hot oven Bake for twenty five to thirty minutes until the cheese is melted golden and totally bubbly The center should be set when you give the dish a gentle shake
- Cool and Add Lettuce:
- Take the casserole from the oven and let it cool for three to five minutes to allow the custard to firm up Once slightly cooled scatter generous handfuls of freshly shredded iceberg lettuce over the top for the familiar burger crunch

Iceberg lettuce is the ingredient I always look forward to because it adds that crisp freshness and brings the burger vibe together My cousin once insisted on doubling the pickles and it turned our family dinner into a hilarious pickle fan club meeting

Cool the casserole completely before covering and refrigerating It keeps well for up to four days in a sealed container For freezing slice and wrap individual portions tightly in plastic and store for a month When ready to eat just reheat gently in the oven for the best texture
Ingredient Substitutions
You can swap ground turkey or chicken for the beef for a lighter twist If you like things spicy add diced pickled jalapenos to the beef layer Try Swiss or Monterey Jack in place of cheddar for a milder flavor and Romaine in place of iceberg brings an extra crunch
Serving Suggestions
I like to top each serving with a dollop of extra burger sauce or pile on sliced tomatoes for more freshness Serve with baked fries or roasted veggies to round out the meal For gatherings set up a toppings bar with extra pickles diced onions and tomato slices for build your own fun
