This keto cheeseburger casserole delivers exactly what the name promises: ground beef, crisp bacon, and melted cheddar baked into something that eats like a cheeseburger without the bun.
The whole thing comes together in under an hour, and the real difference here is the flexibility built into the recipe itself.
Not every version bakes the same. The egg and cream range, from 4 eggs and a quarter cup of cream up to 8 eggs and a full cup, determines whether you get a sliceable quiche or a looser skillet-style bake.
That range is the detail worth deciding before you preheat, because it changes the texture more than any single ingredient swap.
Keto Cheeseburger Casserole Ingredients
Everything here comes from the standard grocery list, no specialty store runs required.
- 1 to 2 lb ground beef — 80/20 is forgiving if that’s what your store stocks
- 6-8 slices bacon, cooked crisp and crumbled
- 4-8 eggs, beaten
- 1-2 cups shredded cheese — Cheddar, Mozzarella, or whatever blend your family finishes off
- 4-6 oz cream cheese, softened enough to spread
- 1/4 cup to 1 cup heavy cream
- 1/4 cup to 1 cup sugar-free tomato sauce or ketchup
- 1 small to medium onion, diced
- Garlic, fresh minced or powder
- Yellow or brown mustard
- Worcestershire sauce
The range on eggs and cream matters. Some versions bake up almost like a quiche with 8 eggs and a full cup of cream; others stay closer to a cheeseburger skillet with just enough to bind.
Same with the sauce — 1/4 cup gives you a hint of ketchup flavor without the carbs adding up, while a full cup turns it saucier.
No food processor, no mandoline, no immersion blender needed. Just a skillet, a 9×13-inch dish if you’re baking it, and a spoon.

How to Make It
- Preheat the oven to 350°F or 375°F. Either temperature works; the lower end gives you a little more margin if your baking dish runs deep.
- Cook the bacon in a large skillet until crispy, then set it aside on a paper towel to cool before chopping.
- Brown the ground beef in the same skillet with diced onion, garlic or garlic powder, and whatever seasonings you’re using. Keep it over medium-high heat until no pink remains, then drain the grease.
- Combine the cooked meat with cream cheese, eggs, and the rest of your wet ingredients in a large bowl. Beat the cream cheese and eggs first if you want a smoother base, or stir everything together until it’s evenly mixed.
- Pour the mixture into a greased 9" by 13" baking dish, or an 8×8 if you want a thicker slice. Spread it to the edges.
- Top with shredded cheese, then the chopped bacon. Some recipes pour heavy cream or an egg mixture over at this stage; the order matters less than getting everything in the dish.
- Bake 30–35 minutes until the top is bubbly and golden brown, and the center is set. The yield is typically 6 servings.
- Let it cool slightly, 5 to 10 minutes, before serving. It slices cleaner, and the flavors settle.

Nutritional Information
A single serving of this casserole lands in the 4–6 net carb range with protein usually clocking between 25 and 30 grams, depending on how much beef and cheese you layer in.
Those numbers come from the usual build: a pound of ground beef, a couple eggs, heavy cream, and two cups of shredded cheddar split between the filling and the top.
Bacon adds fat without moving the carb count much, and the cream cheese binder contributes more richness than sugar.
The calorie spread is wider than the macros suggest. One version built on 80/20 beef and full-fat dairy runs about 486 calories per serving; another with more cheese and a heavier hand on the cream pushes past 700.
Sodium sits high no matter what, mostly from the cheese and any seasoning salt, so if you are watching blood pressure, that is the line item to eyeball rather than the carbs.
Protein can climb surprisingly high.
A leaner beef mix or a larger portion size can push a single serving to 60 grams, which is either a win or a problem depending on whether you are chasing a protein target or trying to stay moderate.
The eggs and dairy do more of the heavy lifting there than the meat alone.

Meal Prep and Storage
Leftovers hold up better than you might expect from a dish this creamy.
An airtight container in the refrigerator keeps the casserole good for up to 4 days, which covers most work-week meal prep without issue. Freeze it for 2 months if you want to play it safe, though some sources say 3.
My own call is to write the earlier date on the lid and treat it as a pleasant surprise if it still tastes great past that.
Assembly the night before works cleanly.
Build the casserole, cover it, and refrigerate; bake it fresh when you are ready. The only shift is adding maybe five extra minutes to the oven time since the dish starts cold.
For reheating, the oven at 350°F for 10 minutes revives the texture best, though a microwave handles single portions fine when speed matters. Thaw frozen portions overnight in the refrigerator first; the texture turns grainy if you rush that step.

Variations and Substitutions
Ground turkey or chicken swaps in cleanly for the beef, though the leaner meat changes both the flavor and the fat content in a way that matters for keto macros.
I’ve found the dish needs a little extra fat back in, a drizzle of olive oil or a pat of butter worked into the turkey as it browns, to keep the richness you’d otherwise miss.
Cheese is where you can really move things around. Cheddar is the baseline, but mozzarella, Monterey Jack, pepper jack, or even a smoked gouda blend all melt well and shift the character of the whole pan.
Pepper jack is the one to reach for if you want heat without sourcing fresh chiles.
Vegetables slip in almost unnoticed. Spinach wilts down to nothing, diced bell peppers add sweetness and crunch, mushrooms bring an earthy depth, and a handful of chopped dill pickles stirred through gives you that classic burger-shack sharpness.
Broccoli or cauliflower rice bulk it out further if you’re feeding more mouths on the same pound of meat.
Plant-based ground meat works here too, though I’d be doing you a disservice if I pretended I’ve tested every brand.
The texture varies widely, and some run wetter than ground beef, so you may need to cook off more moisture before the casserole goes into the oven.
Start with a well-reviewed keto-friendly option and treat the first attempt as a trial run.
What to Serve With It
This casserole carries enough protein and fat to stand alone as a complete meal, which is what makes it a weeknight staple in the first place. No side required, no extra pan to wash.
When I do want to stretch it or balance the richness, a simple green salad with lemon vinaigrette does the job without adding carbs.
Roasted vegetables work too, or cauliflower rice if you are keeping things strictly keto. For something more substantial, cauliflower mash or zucchini noodles round out the plate while staying low-carb.
Green beans almondine or an asparagus salad work if you have a few more minutes, though by then you are cooking a second dish and a casserole is supposed to save you that trouble.
