Keto Bacon Cheeseburger Casserole: The Low-Carb Crowd-Pleaser You’ll Crave
You know those weeknights when you want a drive-thru cheeseburger without the bun, the guilt, or the mystery ingredients?
This is that, but smarter and bigger. Picture a bubbling, cheesy skillet layered with savory beef, smoky bacon, and a tangy “secret sauce” vibe—then baked into a sliceable, meal-prep-friendly feast.
It hits like comfort food, fuels like a macro win, and disappears faster than you can say “leftovers.” Spoiler: there won’t be any.

Why This Recipe Works
This casserole captures the burger joint flavors—beef, cheese, bacon, pickles—without the carb trap.
The egg-and-cream base sets like a custard, holding the meat and cheese in silky, sliceable layers. Smoked paprika and mustard bring that “griddled burger” punch.
And a quick pickle-onion topping adds crunch and tang so every bite tastes like the real deal.

kcalEverything You Need for This Recipe
1.5 lb (680 g) ground beef (80–85% lean)
6 slices thick-cut bacon, chopped
1 small yellow onion, finely diced
2 cloves garlic, minced
1 cup shredded cheddar
1 cup shredded mozzarella (or Monterey Jack)
4 large eggs
3/4 cup heavy cream
2 tbsp tomato paste
1 tbsp yellow mustard (or Dijon)
1 tsp smoked paprika
1/2 tsp onion powder
1/2 tsp garlic powder
Salt and black pepper, to taste
1/4 cup dill pickles, chopped (plus slices for garnish)
2 tbsp chopped green onions or chives (optional)
Cooking oil (avocado or olive) for the skillet
Optional drizzle: 2 tbsp sugar-free ketchup + 1 tbsp mayo
Making This Recipe
- Preheat and prep: Heat oven to 375ÂşF (190ÂşC). Grease a 9×13-inch baking dish or large oven-safe skillet.
- Cook the bacon: In a large skillet over medium heat, crisp the chopped bacon. Remove with a slotted spoon; leave about 1 tbsp bacon fat in the pan.
- Sauté aromatics: Add onion and a tiny splash of oil if needed. Cook 3–4 minutes until translucent. Stir in garlic for 30 seconds.
- Brown the beef: Add ground beef. Season with salt, pepper, smoked paprika, onion powder, and garlic powder. Cook until no pink remains, breaking up chunks. Stir in tomato paste and mustard; cook 1 minute to bloom flavors.
- Drain (lightly): If there’s excessive grease, drain some—but leave a bit for flavor. Stir the bacon back in along with chopped pickles.
- Layer the cheeses: Spread beef mixture evenly in the dish. Sprinkle cheddar and mozzarella on top. Keep a small handful for later, if you like a melty finish.
- Whisk the custard: In a bowl, whisk eggs, heavy cream, a pinch of salt, and black pepper until smooth. Pour evenly over the beef and cheese. It should seep through the layers.
- Bake: Bake 20–25 minutes until set around edges with a slight wobble in the center. Add remaining cheese on top and bake 5–7 more minutes until bubbly and golden.
- Rest and garnish: Let it rest 5–10 minutes to set. Top with green onions and extra pickle slices. Drizzle with the optional sugar-free ketchup–mayo mix for burger vibes.
- Slice and serve: Cut into squares. Serve with a crisp side salad or roasted broccoli. Boom—weeknight win.
Storing & Reheating Tips
- Fridge: Store in an airtight container for up to 4 days.
- Freezer: Wrap portions tightly and freeze up to 2 months.
Thaw in the fridge overnight.
- Reheat: 300°F (150°C) oven for 12–15 minutes, or microwave 60–90 seconds. Add a fresh pickle garnish after reheating for crunch.
- Meal prep tip: Bake in two 8×8 pans—eat one now, freeze the other for your future self. You’re welcome.
Healthy Highlights
- Low-carb, high-satiety: Protein plus fat keeps you full and off the snack carousel.
- Gluten-free by default: No bun, no problem.
- Electrolyte-friendly: Salted beef and bacon help maintain sodium on keto; just don’t go wild, IMO.
- Balanced flavors: Acidic pickles and mustard cut richness so you don’t need a nap after.

What Not to Do
- Don’t skip the rest time. Cutting too soon leads to sloppy slices. Give it 5–10 minutes.
- Don’t drown it in grease. Drain excess fat so the custard sets cleanly.
- Don’t overbake. A dry, rubbery texture is the villain here. Pull when the center barely jiggles.
- Don’t forget acidity. Without pickles/mustard, it’s rich but flat.
You want zing.
- Don’t use ultra-lean beef. Flavor and moisture matter. 80–85% lean is the sweet spot.

Other Versions to Try
- Big Mac-ish: Add shredded lettuce on top after baking and drizzle with sugar-free “special sauce.”
- Jalapeño Popper: Mix in sliced jalapeños and swap mozzarella for pepper jack. Add a little cream cheese to the beef.
- Mushroom Swiss: Sauté mushrooms with the onions; use Swiss instead of cheddar.
- BBQ Bacon: Stir in 2 tbsp sugar-free BBQ sauce and use smoked gouda for a barbecue twist.
- Turkey or bison: Leaner meats work—just add 1–2 tbsp olive oil and don’t skimp on seasoning.
FAQ
Can I make this dairy-free?
Yes. Use full-fat coconut milk instead of cream and a good dairy-free shredded cheese.
Flavor will shift slightly, so keep the mustard and pickles for brightness.
What if I don’t eat pork?
Swap bacon for turkey bacon or finely diced beef bacon. Or skip it and add 1/2 teaspoon liquid smoke for that smoky note.
How do I prevent a watery casserole?
Drain excess beef fat, don’t cover while baking, and avoid watery add-ins (like tomatoes) unless you cook them down first. Let it rest to set the custard, FYI.
Can I make it ahead?
Absolutely.
Assemble up to the egg/cream step, cover, and refrigerate 24 hours. Bake straight from the fridge, adding 5–8 extra minutes.
Is ketchup keto-friendly?
Regular ketchup is loaded with sugar. Use sugar-free ketchup or a DIY version sweetened with erythritol or allulose to keep carbs in check.
What sides pair best?
Go with tangy slaw, a simple arugula salad with lemon vinaigrette, or roasted green beans.
Keep sides crisp and bright to balance richness.
