Ingredients:
- Mashed potatoes– You can make your own or use instant. This is a great way to use up leftover mashed potatoes.
- Lean ground beef – Use ground turkey for a nice alternative.
- Diced sweet onion – Yellow or white onion works great too. Make it even easier for yourself by getting your onions already diced in the produce section of your local grocery store.
- Brown sugar – Dark brown sugar would bring a richer molasses flavor if you like that.
- Worcestershire sauce – This is the recipe’s secret weapon to add a ton of savory, umami flavor.
- Italian breadcrumbs– Make sure you are using the seasoned Italian breadcrumbs and not plain.
- Egg – This helps to bind your meatloaf and keep it together.
- Salt and pepper
- Shredded cheese– You could use cheddar or your favorite melting cheese.
- Bacon– Use bacon bits for a quick alternative!
- Chives– Optional, but it brings some freshness to break up a rich and hearty dish.
Preheat your oven. Preheat your oven to 400°F and spray an 8×8 baking pan with cooking spray.
Make the meatloaf. In a large bowl, add the ground beef, onions, salt, pepper, brown sugar, and Worcestershire sauce and mix until well combined.
Add the binder. Combine the bread crumbs and egg and continue mixing until the breadcrumbs are evenly distributed through the meat mixture and there are no dry spots.
Add the meat to the baking dish. Create an even layer of the meat mixture in the bottom of your prepared baking dish.
Layer the mashed potatoes. Cover the meat with a layer of mashed potatoes, being sure to spread it evenly over the top. You can use a rubber or offset spatula to spread the potatoes all the way to the edges of the pan.
Cover and bake. Cover with aluminum foil and bake for 30 minutes.
Recipe Tips for the Best Results
- Use lean ground beef to avoid excess grease pooling at the bottom of the casserole.
- Warm mashed potatoes spread much more easily than cold ones.
- For extra flavor, stir a little sour cream or butter into the mashed potatoes before layering.
- Don’t overmix the meatloaf -this keeps it tender instead of dense.
- Swap Colby-Jack for cheddar, Monterey Jack, or a cheddar blend if needed.
Freezer Instructions
Freeze before baking:
Assemble the casserole completely (without baking), cover tightly with plastic wrap and foil, and freeze for up to 3 months.
To freeze after baking:
Let the casserole cool completely, then wrap tightly and freeze for up to 3 months.
Reheat from frozen:
Thaw overnight in the refrigerator, then bake at 350°F until hot and bubbly.
