Meatloaf Casserole Made Stepwise

Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures that your casserole cooks evenly and thoroughly.
Step 2: Prepare the Meat Mixture
In a large mixing bowl, combine the lean ground beef, diced onion, parsley, Italian bread crumbs, milk, Worcestershire sauce, eggs, garlic powder, salt, and black pepper. Use your hands or a spoon to mix until just combined; be careful not to overmix.
Step 3: Form the Meatloaf
Transfer the meat mixture into your baking dish and shape it into a loaf. Make sure it’s evenly distributed for consistent cooking.
Step 4: Make the Glaze
In a separate bowl, mix together the ketchup, balsamic vinegar, and brown sugar. Spread this glaze over the top of the meatloaf, ensuring it covers the entire surface.
Step 5: Bake the Meatloaf
Place the baking dish in the preheated oven and bake for 45 minutes. This allows the flavors to meld and the meat to cook through.
Step 6: Add the Mashed Potatoes
After 45 minutes, remove the casserole from the oven and carefully spread the mashed potatoes over the top of the meatloaf. Use a spatula to create an even layer.
Step 7: Add the Cheese
Sprinkle shredded cheddar cheese over the mashed potatoes, covering them entirely.
Step 8: Final Bake
Return the casserole to the oven and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly.
Step 9: Let It Rest
Once done, remove the casserole from the oven and let it rest for about 10 minutes before serving. This helps it set and makes slicing easier.
Healthier Substitutions

If you’re looking to lighten up your Meatloaf Casserole, consider the following substitutions:
- Use ground turkey or chicken instead of lean ground beef for a lower-fat option.
- Swap out regular mashed potatoes for cauliflower mashed potatoes for a low-carb alternative.
- Replace the bread crumbs with oats for a healthier filler.
- Use low-sodium ketchup and Worcestershire sauce to reduce sodium content.
Missteps & Fixes
If you encounter any issues while making your Meatloaf Casserole, here are some common missteps and how to fix them:
- Dry meatloaf: Ensure that you don’t overbake the meatloaf. Use a meat thermometer to check for an internal temperature of 160°F (71°C).
- Mashed potatoes sliding off: Make sure to let the meatloaf cool slightly before adding the potatoes to help them adhere better.
- Uneven cooking: Flatten the meatloaf evenly in the baking dish to ensure even cooking.
- Too much grease: Drain excess fat from the meatloaf before adding the mashed potatoes to prevent the dish from being greasy.
Prep Ahead & Store
For those busy weekdays, prepping ahead can save you time. Here’s how to do it:
- You can prepare the meat mixture a day in advance and store it in the refrigerator until you’re ready to bake.
- Assemble the casserole without baking, cover it tightly, and refrigerate for up to 24 hours. When ready to cook, add an extra 10-15 minutes to the baking time.
- Leftover Meatloaf Casserole can be stored in an airtight container in the refrigerator for up to 3 days.
