- 1 tablespoon Dijon mustard

The Secret to Moist Meatloaf
One of the biggest complaints people have about meatloaf is dryness. Fortunately, this recipe avoids that completely.
The secret lies in soaking the breadcrumbs in milk before mixing them into the beef. This technique, often called a panade, creates moisture throughout the meat mixture and helps produce a tender texture instead of a dense or dry loaf.
Using 85% lean beef also provides just enough fat for flavor without making the dish greasy.
Another important tip: avoid overmixing the meat mixture. Stir just until everything is combined. Overworking ground beef can make meatloaf tough and compact.
How to Make Cheesy Mashed Potato Meatloaf Casserole
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish with oil or nonstick spray to prevent sticking.
Step 2: Soak the Breadcrumbs
In a small bowl, combine the breadcrumbs and milk.
Allow the mixture to sit for about 5 minutes so the breadcrumbs fully absorb the milk. This helps create a tender and juicy meatloaf texture.
Step 3: Make the Meatloaf Mixture
In a large mixing bowl, combine:
- Ground beef
- Soaked breadcrumbs
- Chopped onion
- Garlic
- Eggs
- Worcestershire sauce
- Salt
- Pepper
- Dried thyme
Mix gently until everything is evenly combined.
Avoid pressing or compacting the meat too much, as this can create a dense meatloaf.
Step 4: Shape the Meatloaf
Transfer the meat mixture into the prepared baking dish.
Shape it into a loaf form in the center of the dish.
Step 5: Prepare the Glaze
In a small bowl, stir together:
- Ketchup
- Brown sugar
- Dijon mustard
Spread this mixture evenly across the top of the meatloaf.
The glaze adds the perfect balance of sweet, tangy, and savory flavor while helping the top caramelize beautifully during baking.
Step 6: Bake the Meatloaf
Place the meatloaf into the preheated oven and bake for 50 to 60 minutes.
The internal temperature should reach 160°F (71°C) when measured with a meat thermometer.
While the meatloaf bakes, prepare the mashed potatoes.
Making the Creamiest Mashed Potatoes
Great mashed potatoes can completely elevate this recipe. You want them fluffy, buttery, and smooth enough to spread easily over the meatloaf.
Step 1: Boil the Potatoes
Place the peeled and chopped potatoes into a large pot.
Cover them with cold water and add a generous pinch of salt.
Bring the water to a boil and cook for 15 to 20 minutes, or until the potatoes are fork tender.
Step 2: Mash Until Smooth
Drain the potatoes and return them to the hot pot.
Add:
- Milk
- Butter
Mash until creamy and smooth.
Season with salt and pepper to taste.
For extra creamy potatoes, you can use a potato masher, hand mixer, or potato ricer.
Assemble the Casserole
Once the meatloaf has finished baking, remove it carefully from the oven.
Spread the mashed potatoes evenly over the top of the meatloaf.
Then sprinkle the shredded cheddar cheese generously across the potato layer.
The cheese creates a rich, bubbly topping that makes this dish incredibly satisfying.
Broil Until Golden
Place the casserole under the broiler for 3 to 5 minutes.
Watch carefully as the cheese melts and turns golden and bubbly.
This final step adds delicious texture and creates that irresistible cheesy crust everyone loves.
Let It Rest Before Serving
Allow the casserole to rest for about 10 minutes before slicing.
This helps the layers settle and makes serving much easier.
Sprinkle freshly chopped parsley over the top for a fresh burst of color and flavor.
Serve warm and enjoy every comforting bite.
Tips for the Best Meatloaf Casserole
Use Starchy Potatoes
Russet or Yukon Gold potatoes work best because they mash beautifully and create a fluffy topping.
Don’t Overmix the Beef
Gentle mixing keeps the meatloaf tender.
Drain Excess Grease
If your meatloaf releases extra grease while baking, carefully drain it before adding the mashed potatoes.
Add Extra Cheese
Love cheesy casseroles? Mix some cheddar directly into the mashed potatoes for even more flavor.
Make It Ahead
You can prepare the meatloaf and mashed potatoes ahead of time, then assemble and bake later.
Delicious Variations
This recipe is wonderfully versatile. Here are a few ways to customize it:
Bacon Cheeseburger Style
Add cooked bacon pieces and a little smoked paprika to the meat mixture.
Garlic Parmesan Potatoes
Mix roasted garlic and Parmesan cheese into the mashed potatoes.
Spicy Version
Add diced jalapeños or hot sauce for a spicy kick.
Vegetable Boost
Mix peas, carrots, or corn into the casserole for added nutrition.
What to Serve with Meatloaf Casserole
Since this dish is rich and hearty, lighter side dishes pair wonderfully with it.
Some great options include:
- Steamed green beans
- Roasted broccoli
- Garden salad
- Honey glazed carrots
- Buttered corn
- Dinner rolls
A crisp vegetable side helps balance the creamy and cheesy richness of the casserole.
Storing and Reheating
Refrigerator
Store leftovers in an airtight container for up to 4 days.
Freezer
Freeze tightly wrapped portions for up to 3 months.
Reheating
Warm in the oven at 350°F until heated through, or microwave individual servings.
The flavors often become even better the next day.
