Servings 6 servings

Ingredients

  

• 1.5 pounds (680 g) ground beef (80/20 for the best flavor)
• 6 slices thick-cut bacon, chopped
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon smoked paprika (optional but tasty)
• 2 tablespoons sugar-free ketchup (or regular if carbs aren’t a concern)
• 1 tablespoon yellow mustard (or Dijon for a twist)
• 4 ounces (115 g) cream cheese, softened and cubed
• 4 large eggs
• 1/2 cup heavy cream
• 2 cups shredded cheddar cheese (sharp or medium)
• 2 tablespoons dill pickle relish or finely chopped pickles
• 1 small tomato, seeded and diced (optional garnish)
• 2 green onions, thinly sliced (optional garnish)
• 1 tablespoon olive oil or butter (if needed for sautéing)

Instructions

 

• Preheat the oven. Set to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
• Crisp the bacon. In a large skillet over medium heat, cook chopped bacon until crisp. Transfer to a paper towel-lined plate. Leave about 1 tablespoon of bacon fat in the skillet.
• Sauté the onion and garlic. Add diced onion to the skillet and cook 3–4 minutes until softened. Stir in garlic for 30 seconds until fragrant. If the pan is dry, add a little olive oil or butter.
• Brown the beef. Add ground beef, salt, pepper, and smoked paprika. Cook, breaking it up, until no longer pink. Drain excess grease if needed. Stir in ketchup and mustard for that burger flavor.
• Add the cream cheese. Reduce heat to low and stir in the cubed cream cheese until mostly melted and incorporated. It doesn’t have to be perfectly smooth.
• Make the custard. In a bowl, whisk eggs and heavy cream until smooth. Season with a pinch of salt and pepper.
• Assemble the casserole. Spread the beef mixture evenly in the baking dish. Sprinkle half the cheddar over the beef. Pour the egg-and-cream mixture over top. Finish with the remaining cheddar and half the bacon.
• Bake. Bake for 20–25 minutes, until the center is set and the cheese is bubbling. If you like a deeper golden top, broil for 1–2 minutes at the end, watching closely.
• Top and rest. Let the casserole rest for 5–10 minutes to set. Sprinkle with pickle relish, remaining bacon, diced tomato, and green onions before serving.
• Serve. Slice into squares and enjoy as-is, or add a drizzle of sugar-free ketchup or mustard for extra diner vibes.

Why This Recipe Works

This casserole layers seasoned ground beef, onions, and garlic with a quick egg-and-cream mixture that binds everything together without bread or pasta. The eggs add structure, while cream cheese and heavy cream bring a rich, silky texture.

Crispy bacon and sharp cheddar deliver that unmistakable diner cheeseburger flavor. A touch of mustard, pickles, and tomato on top brightens the dish, balancing the richness. It’s simple, fast, and checks all the low-carb boxes without feeling like a compromise.

Storage Instructions

• Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
• Freeze: Portion into slices, wrap tightly, and freeze for up to 2 months.Thaw overnight in the fridge.

Why This is Good for You

This casserole is low in carbs and provides a solid amount of protein and healthy fats, which can help keep you full and satisfied. Using eggs, beef, and cheese supports satiety while steering clear of refined bread and sugary sauces.

You’ll also get micronutrients like vitamin B12, zinc, and choline from the beef and eggs. Plus, you control the ingredients—less mystery than a diner plate and more room to tweak for your needs.

What Not to Do

• Don’t skip draining excess fat if your beef is very fatty. Too much grease makes the casserole heavy and soggy.
• Don’t add the pickles before baking. They can get rubbery and lose their tang.Add them right before serving.
• Don’t overbake. Once the center is set, pull it. Overbaking can make the custard dry and the cheese oily.
• Don’t overload with sauces. Ketchup and mustard are great for flavor, but too much adds carbs and can thin the mixture.

Recipe Variations

• Mushroom-Swiss: Swap cheddar for Swiss, and sauté 8 ounces of sliced mushrooms with the onions. Add a splash of Worcestershire for depth.
• Spicy Jalapeño: Add 1–2 diced jalapeños to the onion mixture and finish with pepper jack cheese.A pinch of chili flakes boosts the heat.
• BBQ Bacon: Use a low-sugar BBQ sauce in place of ketchup and add smoked Gouda or cheddar. Top with chopped scallions and extra bacon.
• Pickle Lovers: Stir chopped dill pickles into the beef after cooking, then add more on top for a briny kick.
• Turkey or Bison: Swap ground beef for lean ground turkey or bison. Add a tablespoon of olive oil if the mixture seems dry.
• Veg Boost: Fold in 1 cup finely chopped spinach or riced cauliflower to the beef mixture.It adds bulk without many carbs.

FAQ

Can I make this ahead?

Yes. Assemble the casserole up to the baking step, cover, and refrigerate for up to 24 hours. When ready to cook, bake straight from the fridge, adding 5–10 minutes to the time.

Is this keto-friendly?

It is.

Use sugar-free ketchup and check your mustard and relish labels. Per serving, the net carbs stay low while protein and fat stay balanced.

What cheese works best?

Sharp cheddar gives that classic diner flavor and melts well. Monterey Jack, Colby, or a cheddar blend also work.

For a different profile, try Swiss or provolone.

How do I prevent a greasy casserole?

Use 85–90% lean beef or drain well after browning. Keep about a tablespoon of fat for flavor, but remove the rest. Also avoid overbaking, which can separate the cheese and release more oil.

Can I skip the cream cheese?

You can, but the texture will be less creamy.

Substitute with 1/3 cup sour cream or full-fat Greek yogurt whisked into the eggs for a similar tang and body.

What sides go well with it?

A simple green salad with a vinaigrette, roasted broccoli, or sautéed green beans keeps the meal low-carb and fresh. Pickled onions on the side add a bright contrast.

How big is a serving?

For a 9×13-inch dish, plan on 6–8 servings. If you’re tracking macros, slice into even portions and measure once cooled for accuracy.

Can I use pre-cooked bacon?

Yes.

Crumble and warm it briefly for better texture. If you skip cooking bacon in the pan, add a teaspoon of oil when sautéing onions.

Will this work without eggs?

Eggs help set the casserole, but you can try 1 cup of heavy cream mixed with 1/2 cup shredded cheese as a binder. The texture will be softer and more like a skillet bake.

How do I make it dairy-free?

Use a dairy-free cream cheese, coconut cream in place of heavy cream, and a good melting dairy-free cheese.

Expect a slightly different flavor but a similar feel.
