Ingredients
  

Ground beef base
  • 2 lb ground beef Use 85–90% lean for best texture.
  • 1 onion Dice small for even browning.
  • 3 garlic Minced.
  • 2 tbsp yellow mustard
  • 2 tbsp ketchup Sugar-free if keto.
  • 1 tbsp Worcestershire sauce
  • 0.25 salt To taste.
  • 0.25 pepper To taste.
Casserole topping and binding
  • 6 bacon Cooked and crumbled.
  • 4 eggs Beaten.
  • 0.5 cup heavy cream
  • 2.5 cup sharp cheddar cheese Shredded, divided (2 cups for first layer, remainder for last 5 minutes).
  • 1 dill pickle slices For serving.
  • 1 green onions For serving.

Equipment

  • 1 sheet pan

Method
 

Preheat and prep dish
  1. Preheat the oven to 350°F and grease a 9x13 baking dish so the casserole releases easily.
Brown the beef
  1. Brown ground beef with diced onion over medium-high heat until the beef is cooked through, then drain excess fat.
  2. Stir in minced garlic and cook for 30–60 seconds, then add yellow mustard, ketchup, Worcestershire sauce, salt, and pepper until evenly combined.
Assemble layers
  1. Transfer the beef mixture to the baking dish and sprinkle the cooked bacon crumbles over the top.
  2. Whisk the beaten eggs with heavy cream, then pour the mixture evenly over the beef.
  3. Top with 2 cups shredded cheddar so it melts into a golden layer.
Bake and finish
  1. Bake at 350°F for 20–25 minutes, until the eggs are set and the cheese turns golden and bubbly.
  2. Scatter the remaining cheddar in the last 5 minutes of baking for an extra-melty, browned top.
  3. Let it rest briefly, then serve with dill pickle slices and green onions.

Notes

For a less greasy bake, drain the beef well before assembling. Refrigerate leftovers in an airtight container for up to 3 days; reheat in the oven at 325°F until warmed through. Freezing isn’t recommended for best texture. Dietary swap: use sugar-free ketchup to keep it keto-friendly.
