Ingredients
For the Casserole
- 2 lbs (900g) ground beef, 80/20
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 6 large eggs
- 1/2 cup heavy cream
- 2 tbsp yellow mustard
- 1 tbsp Worcestershire sauce
- 1 tsp smoked paprika
- 1 tsp onion powder
- Salt and black pepper, to taste
- 2 1/2 cups shredded cheddar cheese, divided
- 1/3 cup diced dill pickles, plus extra for topping
- 2 tbsp chopped fresh parsley or green onion, for garnish
Ingredient Substitutions
- Ground beef → ground turkey or ground chicken for a leaner version.
- Heavy cream → full-fat coconut cream for a dairy-lighter option (flavor will shift slightly).
- Cheddar → a Colby-Jack or pepper jack blend for a sharper, spicier bite.
- Yellow mustard → Dijon mustard for a more grown-up, tangy flavor.
- Pickles → omit entirely if you're not a pickle fan, or swap in diced pickled jalapeños.
Step-by-Step Instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Have an oven-safe skillet (10–12 inch) ready.
- Brown the beef: Over medium heat, cook the ground beef, onion, and garlic together, breaking up the meat, until the beef is browned and the onion is soft, about 7–8 minutes. Drain excess fat.
- Season the beef: Stir in the mustard, Worcestershire sauce, smoked paprika, onion powder, salt, and pepper. Cook for another 1–2 minutes until fragrant.
- Whisk the egg mixture: In a bowl, whisk together the eggs and heavy cream until smooth.
- Combine: Stir 1 1/2 cups of the cheddar and the diced pickles into the beef mixture, then spread it evenly across the skillet. Pour the egg mixture evenly over the top.
- Top with cheese: Sprinkle the remaining 1 cup of cheddar evenly over the surface.
- Bake: Transfer the skillet to the oven and bake for 20–25 minutes, until the eggs are set and the cheese is bubbly and golden.
- Rest and garnish: Let the casserole rest for 5 minutes, then top with fresh parsley or green onion and extra pickle slices before serving.
Pro Tips
- Use an oven-safe cast iron or stainless skillet to go straight from stovetop to oven — one less dish to wash.
- Pat the browned beef dry of excess grease before adding the egg mixture, or the casserole can turn out oily.
- Shred your own cheese if possible — pre-shredded cheese contains anti-caking starch that can affect melt and texture.
- Let the casserole rest before slicing; it firms up as it cools slightly, making cleaner slices.
Common Mistakes to Avoid
- Skipping the drain step: Too much fat left in the pan makes the eggs greasy and prevents proper setting.
- Overbaking: Pull the casserole once the center is just set — overbaking dries out the eggs and toughens the cheese topping.
- Using a skillet that isn't oven-safe: Check your handle material before it goes in the oven.
- Not seasoning the beef enough: This dish leans on the beef's seasoning for its cheeseburger flavor, so don't be shy with salt, pepper, and paprika.
Variations
🍔 Quick Weeknight Version
Use pre-diced onion and pre-minced garlic to shave 5 minutes off prep, and skip straight from stovetop to broiler for a faster finish on the cheese.
💰 Budget-Friendly Version
Swap in a milder cheddar blend and use ground beef on sale — this recipe is naturally economical since it skips buns, sauces, and extra sides.
👨👩👧 Family-Friendly Version
Leave out the pickles if your kids are picky, and serve with a side of low-carb ketchup for dipping.
🥗 Make-Ahead Version
Brown and season the beef up to 2 days ahead and refrigerate. When ready to bake, simply layer it with the egg mixture and cheese, then bake as directed.
What to Serve With It
- A crisp side salad with ranch or vinaigrette
- Roasted broccoli or green beans
- Garlic butter zucchini noodles
- Cauliflower mash
Storage & Reheating
- Refrigerator: Store in an airtight container for up to 4 days.
- Freezer: Freeze individual portions for up to 2 months; thaw overnight in the fridge before reheating.
- Reheating: Warm in the microwave in 30-second bursts, or reheat covered in a 325°F (165°C) oven for about 10–12 minutes until heated through.
