This low carb 4-ingredient cheeseburger casserole is the kind of dependable dinner that makes a busy week feel easier. It has all the cozy flavor of a cheeseburger in a simple baked dish, with savory ground beef, creamy sauce, and plenty of melted cheddar. Since it comes together with just a handful of ingredients, it is especially helpful on nights when you want something hearty and family-friendly without a long grocery list.
Serve this casserole with a crisp green salad, roasted broccoli, green beans, or simple sliced tomatoes to keep the meal light and balanced. If you are feeding a mixed crowd, it is also nice with pickles on the side or a spoonful of mustard for that classic cheeseburger feel, and a basket of buns can work for anyone at the table who is not eating low carb.
Low Carb 4-Ingredient Cheeseburger Casserole
Servings: 6
Ingredients
2 pounds ground beef
8 ounces cream cheese, softened
1 cup sugar-free ketchup
2 cups shredded cheddar cheese
Directions
1. Preheat the oven to 375°F and lightly grease a medium casserole dish.
2. In a large skillet over medium heat, cook the ground beef until fully browned, breaking it up as it cooks. Drain off excess grease if needed.
3. Stir the cream cheese and sugar-free ketchup into the hot beef until the mixture is smooth, creamy, and evenly combined.
4. Spread the beef mixture into the prepared casserole dish and top evenly with the shredded cheddar cheese.
5. Bake for 15 to 20 minutes, until the cheese is melted, bubbly, and lightly golden on top. Let it rest for 5 minutes before serving.
Variations & Tips
For pickle lovers: Add chopped dill pickles on top after baking or serve them on the side for a classic cheeseburger taste without changing the core recipe.
For picky eaters: Keep the casserole as written for the simplest flavor, then let everyone add their own toppings like mustard, diced tomato, or extra cheese at the table.
For easier cleanup: Use an oven-safe skillet if you have one, so you can mix everything on the stove, top with cheese, and transfer it straight to the oven.
For make-ahead meals: Brown the beef and mix in the cream cheese and ketchup up to a day ahead. Store it in the refrigerator, then spread in the baking dish, top with cheese, and bake when needed.
For the best texture: Let the casserole rest a few minutes before scooping. That short rest helps the creamy sauce settle so each serving holds together better.
