Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Proper preheating ensures the casserole cooks evenly, allowing the meatloaf to bake thoroughly while maintaining its moisture.
2. Make the Meatloaf Base
In a large bowl, combine:
- 1 lb ground beef
- 1/2 cup breadcrumbs
- 1 large egg
- 1/4 cup milk
- 1/4 cup finely chopped onion
- 1 tsp garlic powder
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tbsp Worcestershire sauce
- 1/4 cup ketchup (reserve the remaining 1/4 cup for topping)
Mix gently to avoid overworking the meat. Press the mixture into a greased 9×9-inch baking dish, spreading evenly. Top with the reserved ketchup for a classic meatloaf touch.
3. Bake the Meatloaf Base
Bake the meatloaf in the preheated oven for 20-25 minutes, or until cooked through. Look for the edges to slightly pull away from the dish and no visible pink in the center.
4. Add the Topping
Remove the dish from the oven and:
- Spread 2 cups of prepared mashed potatoes evenly over the meatloaf layer.
- Sprinkle 1 cup shredded cheddar cheese on top.
- Add 4 slices of crumbled, cooked bacon.
5. Bake Again
Return the casserole to the oven and bake for an additional 10-15 minutes until the cheese is melted and bubbly. For a golden finish, broil for 1-2 minutes, watching closely.
6. Garnish and Serve
Sprinkle with chopped green onions or chives, if desired. Allow the casserole to cool for 5-10 minutes to set before slicing and serving.
Tips for Success
Choosing the Right Ground Beef
For the best results, use ground beef with an 80/20 fat ratio. It provides enough fat for flavor and moisture without excessive greasiness.
Perfect Mashed Potatoes
Homemade mashed potatoes offer the best flavor. Add butter and cream for richness, and season with garlic or black pepper for extra depth.
Crispy Bacon
Cook the bacon until crispy before crumbling to ensure it retains its crunch after baking.
Cheese Options
Experiment with other cheeses like mozzarella, pepper jack, or a cheese blend for different flavor profiles.
Variations
Low-Carb Option
Swap mashed potatoes with creamy cauliflower mash for a keto-friendly twist.
Gluten-Free
Use gluten-free breadcrumbs or crushed oats in the meatloaf base.
Add Veggies
Incorporate finely diced carrots or bell peppers into the meat mixture for extra nutrition and flavor.
Protein Substitutes
Replace ground beef with turkey or chicken for a leaner version.
Storage and Reheating
Refrigeration
Store leftovers in an airtight container in the fridge for up to 3-4 days.
Freezing
Wrap the cooled casserole tightly in plastic wrap and foil or portion into freezer-safe containers. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat in a 350°F (175°C) oven, covered with foil, for 15-20 minutes. For a quick option, microwave individual portions in 30-second intervals.
