Ingredients Method

Ingredients

  

• Ground beef (85–90% lean)
• Bacon (thick-cut preferred)
• Yellow onion, finely diced
• Garlic, minced
• Eggs
• Heavy cream (or half-and-half)
• Cheddar cheese, shredded
• Cream cheese, softened
• Pickles, chopped (dill)
• Tomato paste
• Sugar-free ketchup (or lowest-sugar you can find)
• Yellow mustard
• Worcestershire sauce (check for low sugar)
• Smoked paprika
• Salt and black pepper
• Olive oil or avocado oil
• Optional toppings: sliced green onions, sesame seeds, hot sauce

Method

 

1. Preheat and prep the pan. Heat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with oil or butter.
2. Crisp the bacon. Cook bacon in a large skillet over medium heat until crisp. Remove to a paper towel–lined plate and crumble when cool. Reserve 1–2 tablespoons of bacon grease in the pan.
3. Sauté onions and garlic. In the bacon drippings, cook the diced onion until soft and lightly golden, about 5–7 minutes. Stir in the garlic for 30 seconds until fragrant.
4. Brown the beef. Add ground beef to the skillet. Season with salt, pepper, and smoked paprika. Cook, breaking it up, until no longer pink. Drain excess grease if needed.
5. Build that burger flavor. Stir in tomato paste, mustard, ketchup, and Worcestershire. Let it simmer 2–3 minutes so the flavors meld. Taste and adjust seasoning.
6. Whisk the custard base. In a bowl, whisk eggs, heavy cream, a pinch of salt, and pepper until smooth. Set aside.
7. Make it cheesy. Off the heat, stir cream cheese into the beef mixture until melted and creamy. Fold in half the shredded cheddar and most of the crumbled bacon (save some for topping). Add chopped pickles for that classic bite.
8. Assemble. Spread the beef mixture evenly in the greased baking dish. Pour the egg-and-cream mixture over the top, letting it seep through. Sprinkle the remaining cheddar and reserved bacon over everything.
9. Bake. Place in the oven and bake 20–25 minutes, until the center is set and the top is bubbly and lightly golden. If needed, broil for 1–2 minutes for extra color.
10. Rest and serve. Let the casserole rest 10 minutes so it slices cleanly. Top with green onions and sesame seeds if you like. Slice into squares and serve warm.

Why This Recipe Works

This casserole hits that perfect middle ground between comfort food and smart eating. The beef, bacon, and cheese deliver big flavor while the egg mixture binds it into a sliceable bake that’s low in carbs.

A quick sauté of onions and a little mustard and ketchup (low sugar) bring classic burger notes. There’s no crust or bread, so you save carbs without sacrificing texture. Best of all, it’s a one-pan bake that feeds a family and makes leftovers you’ll look forward to.

How to Make It

1. Preheat and prep the pan. Heat your oven to 375°F (190°C).

   Grease a 9×13-inch baking dish with oil or butter.

2. Crisp the bacon. Cook bacon in a large skillet over medium heat until crisp. Remove to a paper towel–lined plate and crumble when cool. Reserve 1–2 tablespoons of bacon grease in the pan.
3. Sauté onions and garlic. In the bacon drippings, cook the diced onion until soft and lightly golden, about 5–7 minutes.

   Stir in the garlic for 30 seconds until fragrant.

4. Brown the beef. Add ground beef to the skillet. Season with salt, pepper, and smoked paprika. Cook, breaking it up, until no longer pink.

   Drain excess grease if needed.

5. Build that burger flavor. Stir in tomato paste, mustard, ketchup, and Worcestershire. Let it simmer 2–3 minutes so the flavors meld. Taste and adjust seasoning.
6. Whisk the custard base. In a bowl, whisk eggs, heavy cream, a pinch of salt, and pepper until smooth.

   Set aside.

7. Make it cheesy. Off the heat, stir cream cheese into the beef mixture until melted and creamy. Fold in half the shredded cheddar and most of the crumbled bacon (save some for topping). Add chopped pickles for that classic bite.
8. Assemble. Spread the beef mixture evenly in the greased baking dish.

   Pour the egg-and-cream mixture over the top, letting it seep through. Sprinkle the remaining cheddar and reserved bacon over everything.

9. Bake. Place in the oven and bake 20–25 minutes, until the center is set and the top is bubbly and lightly golden. If needed, broil for 1–2 minutes for extra color.

Storage Instructions

• Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Slice into portions, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge.
• Reheat: Warm individual slices in the microwave for 60–90 seconds or in a 325°F (165°C) oven for 10–15 minutes until hot.

Benefits of This Recipe

• Low carb and satisfying. You get plenty of protein and fat, with minimal carbs, so it keeps you full without the post-meal slump.
• Weeknight-friendly. Everything cooks in one skillet before baking, and the oven time is short.
• Great for meal prep. Easy to portion, reheat, and pack for lunches.
• Family-approved flavors. It tastes like a cheeseburger, so even picky eaters are on board.
• Flexible and customizable. You can swap cheeses, adjust seasonings, or add low-carb veggies without changing the core idea.

What Not to Do

• Don’t skip draining excess fat. If your beef is very fatty, drain the pan to avoid a greasy casserole.
• Don’t overbake. If it stays in the oven too long, the eggs turn rubbery.

  Pull it when the center just sets.

• Don’t forget to season. Under-seasoned beef makes a bland casserole. Taste the mixture before baking.
• Don’t add watery vegetables raw. If using mushrooms or zucchini, sauté and drain them first so they don’t water down the bake.
• Don’t use sweet, high-sugar condiments. Stick with sugar-free or low-sugar ketchup to keep carbs in check.

Variations You Can Try

• Spicy Jalapeño. Add sliced jalapeños and pepper jack cheese. A dash of hot sauce in the egg mixture kicks it up.
• Mushroom Swiss. Swap cheddar for Swiss and fold in sautéed cremini mushrooms with the beef.
• Bacon Double Cheeseburger. Mix in an extra cup of cheese and another half batch of bacon for maximum indulgence.
• BBQ Bacon. Use a low-sugar BBQ sauce in place of ketchup and add a pinch of chili powder.
• Dill Pickle Lovers. Stir extra chopped pickles into the beef and scatter more on top after baking for crunch.
• Turkey or Bison Swap. Use ground turkey or bison if you prefer a leaner meat.

  Add a splash of oil and don’t overcook to keep it moist.

• Veggie Boost. Fold in sautéed spinach or riced cauliflower for extra volume with minimal carbs.
