Ingredients
-
2 pounds Ground beef (80/20 lean for flavor)
-
6 to 8 slices Bacon (Cooked and crumbled)
-
1 medium Yellow onion (Diced)
-
2 cloves Garlic (Minced)
-
4 large Eggs
-
1/2 cup Heavy cream (Or sour cream)
-
2 tablespoons Sugar-free ketchup
-
1 tablespoon Yellow mustard
-
2 cups Sharp cheddar cheese (Shredded)
-
1/2 teaspoon Salt
-
1/2 teaspoon Black pepper
-
(Optional: Dill pickles and sesame seeds for garnish)
Instructions
-
Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish.
-
In a large skillet over medium-high heat, brown the ground beef and diced onion together until the meat is no longer pink.
-
Drain the excess grease thoroughly from the skillet and stir in the minced garlic for 1 minute until fragrant.
-
Spread the seasoned ground beef and onion mixture evenly into the bottom of the prepared baking dish.
-
In a medium mixing bowl, whisk together the eggs, heavy cream, sugar-free ketchup, mustard, salt, and pepper until well combined.
-
Stir in half of the shredded cheddar cheese and half of the crumbled bacon into the egg mixture.
-
Pour the egg and cream mixture over the beef, using a spatula to ensure it reaches the bottom of the dish.
-
Sprinkle the remaining cheddar cheese and the rest of the bacon evenly over the top.
-
Bake for 30 to 35 minutes, or until the center is set and the cheese is bubbly and golden.
-
Remove from the oven and let it stand for 5 minutes before slicing; garnish with pickles and sesame seeds if desired.
Why This Recipe Works
-
The combination of heavy cream and eggs creates a “savory custard” that acts as a low-carb binder, providing a dense, satisfying structure that mimics a bun’s heartiness.
-
Browning the beef with onions first provides a foundational “umami” flavor that penetrates the entire dish as it bakes.
-
Using sugar-free ketchup and yellow mustard inside the custard ensures that the signature “burger sauce” flavor is infused into every bite rather than just sitting on top.
-
High-fat cheddar and smoky bacon provide a sharp, salty contrast to the rich beef, creating a perfectly balanced and indulgent savory profile.
Tips for Best Results
Drain the grease. This is a vital step. If too much fat is left in the beef, it will separate during the bake and leave the egg mixture sitting in a layer of oil.
Use fresh-shredded cheese. Pre-shredded cheeses often contain potato starch or cellulose to prevent clumping, which can add unnecessary carbs and prevent the cheese from melting as smoothly.
Let it rest. Allow the casserole to sit for at least 5 minutes after removing it from the oven. This helps the egg binder “set,” making it much easier to cut into neat, sturdy portions.
Variations & Substitutions
For a “Spicy Kick,” substitute the sharp cheddar with Pepper Jack cheese and add a small can of diced green chiles to the beef mixture.
If you prefer a “Deluxe Burger” version, top the baked casserole with shredded lettuce, diced fresh tomatoes, and a drizzle of sugar-free burger sauce before serving.
To make this “Mushroom Swiss” style, sauté sliced mushrooms with the beef and swap the cheddar for Swiss cheese.
Frequently Asked Questions
How should I store and reheat leftovers?
Store in an airtight container in the fridge for up to four days. Reheat in the oven at 325°F or in the microwave for a quick, low-carb lunch; it stays remarkably moist even after reheating.
Can I make this ahead of time?
Yes. You can brown the beef and prepare the egg mixture up to 24 hours in advance. Store them separately in the fridge and combine them just before you are ready to bake.
Is this “Keto-Friendly”?
Absolutely. With high fats, moderate protein, and very low carbohydrates, this dish is a staple for ketogenic diets. Just ensure your condiments are sugar-free.
Why is my casserole watery?
This usually happens if the onions or beef weren’t drained well. If you find extra liquid after baking, simply use a paper towel to blot the edges; it will still taste delicious.
