Low-Carb Cheeseburger Casserole

This Low-Carb Bacon Cheeseburger Casserole packs all the juicy burger flavors—savory beef, crisp bacon, and melty cheddar—without the bun. As a nutritionist and busy mom, I love that it’s truly high protein and family-friendly. It serves 6 and takes about 50 minutes total, perfect for weeknights or meal prep.

I first made this on a game night when nobody wanted to grill. The creamy egg custard holds everything together like a tender, quiche-style base, while sharp cheddar bubbles into a golden lid. The result is cozy, satisfying, and easy to slice after a short rest. You’re going to love this one.

Ingredients for Low-Carb Bacon Cheeseburger Casserole

I always crisp the bacon first—the rendered fat builds deep flavor for the onions and garlic. In my experience, sharp cheddar gives the best cheeseburger bite.

• 1 lb ground beef (I recommend 85% lean for flavor/balance)
• 6 slices bacon, diced (cook until crisp—pro tip: don’t rush this)
• 1 medium onion, chopped (sweetness as it softens)
• 2 cloves garlic, minced (my go-to for savory depth)
• 6 large eggs
• ½ cup heavy cream (custard base; my preference is full-fat)
• 1 tbsp yellow mustard (I recommend classic yellow for tang)
• 1 tbsp Worcestershire sauce
• 2 cups shredded cheddar, divided (I usually use sharp)
• Salt and black pepper, to taste
• Chopped green onions, diced tomatoes (optional garnish)

Step-by-Step Instructions

I recommend draining the beef thoroughly and letting the mixture cool slightly before adding the custard—this prevents scrambling and greasy edges.

Step 1: Heat oven to 375°F (190°C). Grease an 8×8-inch baking dish.
Step 2: Cook bacon in a large skillet until crisp; remove with a slotted spoon, leaving the drippings.
Step 3: Sauté onion and garlic 2–3 minutes until translucent and fragrant.
Step 4: Add beef; cook until browned. Drain very well (blot if needed). Stir bacon back in; cool 5–10 minutes.
Step 5: Whisk eggs, cream, mustard, Worcestershire, salt, and pepper until smooth.
Step 6: Spread meat in the dish. Top with 1 cup cheddar. Pour custard evenly over; finish with remaining cheese.
Step 7: Bake 25–30 minutes until the center is set with a slight jiggle or reads ~165°F. Rest 5–10 minutes before slicing.

What to Serve with Low-Carb Bacon Cheeseburger Casserole

Bright, crunchy sides balance the rich, cheesy bake—and they make smart internal pairings for readers.

Cottage Cheese Flatbread: Tearable, high-protein bread for dipping or open-face slices.

Cottage Cheese Chicken Salad: Cool, tangy counterpoint; serve in small side portions over greens.

Keto Zucchini Lasagna (for a low-carb potluck spread): Another comfort classic with similar flavors for the week’s meal prep.

Turkey Chili (make-ahead option): Hearty partner for game days; keeps the menu protein-forward.

Storage & Serving Tips

Cool leftovers within 2 hours; refrigerate up to 4 days or freeze up to 3 months (wrap tightly or vacuum-seal to prevent freezer burn).

Reheat at 350°F for 10–15 minutes for best texture; microwave in short bursts if needed. For a 9×13 pan, double ingredients and bake 30–35 minutes, checking the center for doneness.
