This Cheesy Meatloaf Mashed Potato Casserole combines two classic comfort foods in one baking dish. Creamy mashed potatoes cover the bottom, while seasoned mini meatloaves are baked on top and finished with a generous layer of melted cheddar cheese.
It is hearty, simple, and perfect for a family dinner when you want something warm and filling without preparing several separate dishes.
The individual meatloaf portions also make it easy to serve, and the melted cheese gives the casserole the same rich golden appearance shown in your photo.

Instructions
1. Make the Mashed Potatoes
Add the peeled potatoes to a large pot and cover them with cold salted water.
Bring to a boil and cook for about 15 minutes, or until the potatoes are completely tender.
Drain well.
Add butter, milk, sour cream, salt, and pepper.
Mash until smooth and creamy.
Spread the mashed potatoes evenly across the bottom of a greased 9×13-inch baking dish.
2. Prepare the Meatloaf Mixture
Preheat your oven to 375°F (190°C).
In a large bowl, combine ground beef, chopped onion, breadcrumbs, milk, egg, ketchup, Worcestershire sauce, garlic powder, onion powder, parsley, paprika, salt, and pepper.
Mix gently until everything is combined.
Avoid overmixing because it can make the meatloaf dense.
3. Shape the Mini Meatloaves
Divide the meat mixture into approximately 6 equal portions.
Shape each portion into a thick oval meatloaf.
Arrange them over the mashed potatoes, leaving a small amount of space between each piece.
4. Bake
Place the casserole uncovered in the oven.
Bake for approximately 25–30 minutes, or until the meatloaves are nearly cooked through.
Ground beef should reach a safe internal temperature of 160°F (71°C).
5. Add the Cheese
Remove the casserole from the oven.
Sprinkle plenty of shredded cheddar over each meatloaf.
Add bacon if you’re using it.
Return the dish to the oven for another 5–10 minutes, until the cheese is fully melted and bubbling.
For the browned cheesy appearance in your photo, broil for roughly 1–2 minutes at the end while watching carefully.
6. Finish
Sprinkle dried or fresh parsley over the melted cheese.
Let the casserole rest for approximately 5 minutes before serving.
Tips for the Best Meatloaf Casserole
Don’t make the mashed potatoes too thin because they need to support the meatloaves.
Sharp cheddar gives the strongest cheesy flavor.
For softer and juicier meatloaf, mix the meat only until the ingredients are combined.
You can also brush a little BBQ sauce or ketchup over the meatloaves before adding the cheese.
Optional Gravy
A simple brown gravy works extremely well with this casserole.
Prepare about 1–2 cups of beef gravy and spoon it over each serving.
That also matches other popular mashed-potato meat casseroles, which commonly pair the potatoes and meat with gravy or a savory sauce.
What to Serve With It
Because this casserole already includes meat and potatoes, keep the sides simple:
- Green beans
- Steamed broccoli
- Roasted carrots
- Garden salad
- Corn
- Dinner rolls
Storage
Allow leftovers to cool and transfer them to an airtight container.
Store in the refrigerator for up to 3–4 days.
Reheat individual portions in the microwave or cover the casserole with foil and warm it in a 350°F oven.
FAQ
Can I prepare this casserole ahead of time?
Yes. Prepare the mashed potatoes and meatloaf mixture, assemble everything, cover, and refrigerate. Bake it when you’re ready to serve.
Can I use ground turkey instead?
Yes. Ground turkey works, although it is leaner than beef and can dry out more easily.
What cheese works best?
Sharp cheddar matches the photo best. Colby Jack, Monterey Jack, or a cheddar-mozzarella mixture can also work.
Can I use leftover mashed potatoes?
Absolutely. This is actually a great way to use leftover mashed potatoes.
Why did my meatloaf turn out dry?
It may have been overcooked or overmixed. Remove it once the center reaches the safe temperature.
Can I add bacon?
Yes. Cooked bacon can be sprinkled beneath or over the cheddar before the final bake.
