Cheesy Loaded Meatloaf Casserole creates the ultimate comfort food experience by combining two beloved classics into one irresistible dish. This hearty creation features a perfectly seasoned meatloaf base crowned with creamy mashed potatoes, melted cheddar cheese, and crispy bacon crumbles. Each forkful delivers layers of flavor and texture – from the savory, juicy meat layer to the creamy potato topping and the smoky crunch of bacon that ties everything together.
When I first served this at our family Sunday dinner, my father-in-law, who typically requests "just a small portion," helped himself to seconds without hesitation. The empty casserole dish spoke volumes about its appeal.
Essential Elements
- Ground beef: Choose 80/20 for the perfect balance of flavor and juiciness
- Breadcrumbs: Provide structure while keeping the meat tender
- Mashed potatoes: Create the creamy layer that defines this casserole
- Sharp cheddar: Melts beautifully while adding distinct flavor
- Crispy bacon: Contributes essential smoky notes and textural contrast
- Worcestershire sauce: Deepens the meaty flavors with umami richness
- Fresh onion: Adds aromatic sweetness throughout the meatloaf

Creating Perfect Casserole
- Meatloaf Foundation:
- Mix ingredients with a light touch to avoid compacting. Press evenly into the baking dish, creating a level surface for toppings.
- First Bake:
- Allow meatloaf to cook partially before adding toppings. This ensures proper doneness without overcooking the cheese layer.
- Potato Application:
- Spread warm mashed potatoes carefully over the partially baked meatloaf. Create an even layer for consistent cheese melting.
- Final Assembly:
- Layer cheese and bacon strategically for maximum coverage. Finish with brief broiling for golden perfection.
My grandmother always said the secret to great meatloaf was "mixing with love but not too much." This recipe honors her wisdom by creating a tender meat base that still holds its shape under the toppings.
Perfect Pairings
Serve this hearty casserole with a crisp green salad dressed with vinaigrette to balance the richness. Steamed broccoli or green beans provide a fresh contrast, while warm dinner rolls are perfect for soaking up any savory juices.
Creative Variations
Experiment with adding diced bell peppers or carrots to the meatloaf for extra nutrition. Try substituting ground turkey for a lighter version, or create a Tex-Mex twist with pepper jack cheese and taco seasoning.

Storage Success
Store leftovers covered in the refrigerator for up to three days. Reheat individual portions in the microwave, or warm the entire casserole, covered with foil, in a 325°F oven until heated through.
