Low-Carb Bacon Cheeseburger Casserole

This Low-Carb Bacon Cheeseburger Casserole packs all the flavors of a classic cheeseburger into an easy, oven-baked dish that never feels like a compromise. My family begs for this creamy cheesy weeknight wonder and it always disappears before I can save leftovers.

The first time I made this was during a busy soccer season when everyone was craving comfort food. Now it is my go-to anytime I want easy but satisfying.

Ingredients

• Ground beef: for a juicy meaty base look for 80 to 85 percent lean for best balance of flavor
• Bacon: cooked and crumbled adds smoky crunch use a thicker cut for bold flavor
• Small onion: diced for a boost of savoriness pick one with shiny skins for freshness
• Garlic: minced for a kick of aroma fresh cloves will make a difference
• Salt: for simple seasoning sea salt has a clean taste
• Black pepper: for mild heat grind just before using for best flavor
• Paprika: brings color and a subtle smoky edge try smoked paprika if you have it
• Dried oregano: for herbal depth always check for a vibrant green color in dried herbs
• Sugar free ketchup: to keep things low carb choose one with no added sweeteners
• Mustard: for tang I like using classic yellow for that cheeseburger taste
• Mayonnaise: for richness go for a real egg mayonnaise for best texture
• Shredded cheddar cheese: for cheesy melt choose sharp cheddar and shred it yourself
• Shredded mozzarella cheese: for a gooey pull whole milk mozzarella works best
• Large eggs: to bind everything together fresh and room temperature are easiest to whisk

Step-by-Step Instructions

Prepare the Oven and Dish:

Preheat the oven to 350F or 175C and lightly grease a 9 by 13 inch baking dish with butter or cooking spray. This keeps the casserole from sticking and helps with cleanup.

Brown the Ground Beef:

In a large skillet or frying pan over medium heat cook the ground beef until no pink remains. Break up the meat with a spoon as it cooks. Drain off any extra fat to avoid greasiness in the final casserole.

Saute Onion and Garlic:

Add the diced onion and minced garlic right into the beef in the skillet. Stir and cook for about two to three minutes until the onion is soft and translucent. This step makes the whole casserole base taste rich and savory.

Season the Meat:

Mix in the salt black pepper paprika and dried oregano. Stir well and let everything cook for another minute to bloom the spices and blend the flavors.

Stir in Burger Sauces:

In a small mixing bowl stir together the sugar free ketchup mustard and mayonnaise until combined. Add this sauce into the skillet with the beef mixture and stir to coat every bite. This creates the classic cheeseburger flavor.

Transfer to Baking Dish:

Spoon the meat and sauce mixture evenly into the prepared baking dish. Make sure to level it out so every bite bakes the same.

Top with Bacon:

Evenly sprinkle all the cooked crumbled bacon over the meat base for a burst of smoky flavor in every piece.

Add the Egg Mixture:

Whisk the large eggs in a clean bowl until smooth and a little frothy. Pour the eggs evenly over the bacon and meat mixture so it sets up the casserole and binds everything together.

Layer on the Cheese:

Distribute the shredded cheddar and mozzarella cheese across the top for a bubbly golden crust once baked.

Bake the Casserole:

Place the dish in your preheated oven. Bake for twenty five to thirty minutes or until the cheese is fully melted and starting to brown on the edges. The casserole should look bubbly.

Rest and Serve:

Let the casserole cool for five to ten minutes out of the oven so the layers firm up before slicing. This rest time ensures easy serving and perfect portions.

Save

My absolute favorite part is the crispy bacon on top. I still think of the first time I made this for my family and seeing everyone go back for seconds made me want to try new creative casseroles in the future.

Storage Tips

Tuck leftovers into airtight containers and store in the fridge up to four days. For longer keeping divide slices and freeze wrapped well in plastic or foil. Reheat individual portions in the microwave or oven until piping hot. The cheesy top stays gooey even after reheating so do not worry about flavor loss.

Ingredient Substitutions

Swap ground turkey or chicken for beef to lighten things up. Use pepper jack or Monterey jack cheese for an extra spicy kick. Try turkey bacon or omit it entirely for a pork free option. Avocado mayo works great as a dairy free swap.

Serving Suggestions

Serve this casserole with a crisp green salad or roasted broccoli for a balanced meal. If you are not strictly low carb add a scoop of coleslaw or a handful of pickle chips on the side. For brunch it pairs beautifully with a simple cucumber tomato salad.

Cultural Note

Cheeseburger casseroles like this one are a nostalgic twist on classic American diner food. By skipping the bun and using low carb swaps you keep all the flavors of a summer cookout but in scoopable weeknight form.
