The Allure of the Casserole: Why We Love This Dish
Casseroles are a cornerstone of home cooking for a reason. They are the epitome of comfort food, a one-pan wonder that simplifies cooking and cleanup. This particular casserole takes two beloved classics—meatloaf and mac and cheese—and brilliantly combines them. The bottom layer is a savory, juicy meatloaf, while the top layer is a creamy, cheesy pasta bake. It’s the best of both worlds, a dish that is both familiar and excitingly new.
- Family-Friendly: The combination of ground beef, pasta, and cheese is a guaranteed hit with kids and adults alike.
- Perfect for Meal Prep: This casserole is fantastic for making ahead of time. You can assemble it and keep it in the fridge, ready to bake for a busy weeknight.
- Feeds a Crowd: This is a hearty, filling dish, making it perfect for family gatherings, potlucks, or for having delicious leftovers for the next few days.
Ingredients Deep Dive: Choosing the Best Components
The Meatloaf Layer: The Savory Foundation
The foundation of this dish is a flavorful, juicy meatloaf. Let’s break down the key components:
- Ground Beef: A lean ground beef (around 85/15) is the perfect choice. It has enough fat to keep the meatloaf moist and flavorful, but not so much that the casserole becomes greasy. For a richer flavor, you can use a mix of ground beef and ground pork.
- Breadcrumbs: These are essential for the texture of the meatloaf. They help to bind the meat together and, more importantly, they absorb the juices, keeping the meatloaf tender and preventing it from becoming a dense, dry brick.
- The Binder and Flavorings: An egg is used to bind everything together. Finely chopped onions, garlic powder, and a little Worcestershire sauce add essential savory and umami notes.

The Cheddar Shells Layer: The Creamy Topping
The top layer is essentially a quick and easy, yet incredibly delicious, mac and cheese.
- The Pasta: Medium pasta shells are the ideal choice for this recipe. Their cup-like shape is perfect for trapping the creamy cheese sauce, ensuring that every bite is a cheesy delight. Other shapes like elbow macaroni or rotini can also work well.
- The Cheese Sauce: This recipe uses a brilliant shortcut for a creamy sauce: a can of condensed tomato soup, milk, and shredded cheddar cheese. The condensed soup provides a tangy, savory tomato base and a velvety texture, while the milk thins it out and the cheddar provides that classic, rich cheese flavor.
- The Cheese: A sharp cheddar cheese will provide the boldest, most classic flavor. However, a medium cheddar or a Colby Jack will also be delicious. As always, for the best and smoothest melt, it’s highly recommended to shred your own cheese from a block.

Ingredients
- For the Meatloaf Layer:
- 1.5 lbs lean ground beef (85/15)
- 1 cup breadcrumbs (Italian-style or plain)
- 1/2 cup finely chopped yellow onion
- 1 large egg, lightly beaten
- 1/4 cup milk
- 1 tbsp Worcestershire sauce
- 1 tsp garlic powder
- 1 tsp salt
- 1/2 tsp black pepper
- For the Cheddar Shells Layer:
- 8 oz medium pasta shells
- 1 can (10.75 oz) condensed tomato soup
- 1/2 cup milk
- 2 cups shredded sharp cheddar cheese, divided
Step-by-Step Instructions
- Preheat Oven and Prepare the Pasta: Preheat your oven to 350°F (175°C). Bring a large pot of salted water to a boil and cook the pasta shells according to the package directions until they are *al dente*. Drain well and set aside.
- Make the Meatloaf Mixture: In a large mixing bowl, combine the ground beef, breadcrumbs, chopped onion, beaten egg, 1/4 cup of milk, Worcestershire sauce, garlic powder, salt, and pepper. Use your hands to gently mix all the ingredients together until they are just combined. Be careful not to overmix, as this can make the meatloaf tough.
- Form the Meatloaf Layer: Press the meatloaf mixture firmly and evenly into the bottom of a greased 9×13-inch baking dish. This will create the savory foundation for your casserole.
- Create the Cheddar Shells Mixture: In the same large bowl (no need to wash it), combine the cooked and drained pasta shells, the can of condensed tomato soup, the 1/2 cup of milk, and 1.5 cups of the shredded cheddar cheese. Stir until the pasta is evenly coated in the creamy, cheesy sauce.
- Assemble the Casserole: Pour the cheddar shells mixture evenly over the top of the meatloaf layer in the baking dish. Spread it out to cover the meatloaf completely.
- Top with Cheese and Bake: Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top of the casserole.
- Bake to Perfection: Bake, uncovered, for 45-50 minutes, or until the meatloaf is cooked through (an instant-read thermometer should register 160°F or 70°C), and the cheese on top is melted, bubbly, and beautifully golden brown.
- Rest and Serve: Let the casserole cool for at least 10-15 minutes before slicing and serving. This crucial resting period allows the layers to set, making it much easier to serve clean portions. Garnish with fresh parsley if desired.
Pro-Tips for Casserole Success
- Don’t Overmix the Meatloaf: The most common mistake that leads to a tough, dense meatloaf is overworking the meat. Mix the ingredients with your hands only until they are just combined.
- Cook the Pasta Al Dente: It’s very important to cook your pasta 1-2 minutes less than the package directs. The pasta will continue to cook in the oven as it bakes, and this will prevent it from becoming soft and mushy.
- The Resting Period is Non-Negotiable: It might be tempting to dig in right away, but letting the casserole rest for 10-15 minutes is essential. This allows the juices in the meatloaf to redistribute and the cheese sauce to set up, ensuring a perfect slice every time.
Creative Variations and Customizations
- Different Proteins: For a leaner casserole, you can substitute the ground beef with ground turkey or ground chicken. Ground pork or Italian sausage would also be delicious and add a different flavor profile.
- Boost the Veggies: You can easily sneak in extra vegetables for more nutrition. Add finely shredded carrots or zucchini to the meatloaf mixture, or sauté some chopped mushrooms or spinach and mix them in with the cheddar shells.
- Flavor Twists: For a smoky flavor, add a teaspoon of smoked paprika to the meatloaf. For a little heat, add a pinch of red pepper flakes. You can also swap the condensed tomato soup for a can of condensed cheddar cheese soup for an even cheesier experience.

Frequently Asked Questions (FAQs)
What can I use instead of ground beef?
If you want a different protein, you can easily substitute the ground beef with an equal amount of ground turkey, ground chicken, or ground pork. For a vegetarian version, you can use a plant-based meat alternative or a mixture of lentils and finely chopped mushrooms.

When stored properly in an airtight container, your leftover casserole should last for up to 3-4 days in the refrigerator, and the flavors often meld and taste even better the next day!
Can I freeze this casserole?
