Ingredients You’ll Need
Alright my culinary comrades, grab your shopping list because you’re gonna need:
- 1 lb ground beef (the star of the show)
- 2 cups uncooked macaroni (the ultimate sidekick)
- 2 cups shredded cheddar cheese (because more cheese is always better)
- 1/2 cup diced onion (for that sweet touch)
- 1/2 cup breadcrumbs (to hold it all together, like friendship)
- 1 large egg (the binder of awesomeness)
- 1/4 cup milk (for that moist meatloaf action)
- 2 tbsp butter (for your cheese sauce magic)
- 2 cups milk (for said cheesy magic)
- 1 tsp salt (flavor party)
- 1/2 tsp pepper (a little kick)
- 1/2 tsp paprika (for color and flair)
- 1/2 tsp dry mustard (because why not)
- 2 tbsp flour (to thicken things up)
You got all that? Sweet! Let’s dive into the cooking adventure of a lifetime.
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). This step is so important that we need to say it twice. Nope, not really, but please don’t skip it. You’ll ruin everything.
- In a mixing bowl, combine the ground beef, onion, breadcrumbs, egg, milk, salt, and pepper. Mix well until the ingredients become one glorious meat concoction. It’s kind of like forming a mini meaty mountain.
- Press the meat mixture into a greased baking dish. Make sure it’s tightly packed. We want the world to know there’s serious meatiness happening here.
- Bake the meatloaf for 20 minutes. Remember, patience is a virtue, but don’t go wandering off to binge-watch cat videos or you might forget.
- While it bakes, cook the macaroni according to package directions; drain and set aside. It’s like giving the pasta a brief spa treatment before the main event.
- For the cheese sauce, melt the butter in a saucepan over medium heat. Get that butter melting like it’s on vacation.
- Stir in the flour and cook for one minute. It will start to clump together like high school drama—just keep stirring until it’s nice and combined.
- Gradually whisk in the milk until thickened. Get ready to whisk like you mean it. You don’t want any lumps in this cheesy goodness!
- Season the cheese sauce with salt, pepper, paprika, and dry mustard. Give it a little taste; just don’t burn your tongue like I did once. Ouch.
- Stir in the shredded cheese until melted. This step is pure magic. It will feel like a cheesy lovelight is shining down on you.
- Combine the cooked macaroni with the cheese sauce. Stir like you’re mixing up a potion for world domination.
- Pour the macaroni and cheese over the baked meatloaf layer. Spread it evenly, make it look all saucy and inviting.
- Top with remaining cheese. More cheesy goodness is always a good idea. Trust me.
- Bake for an additional 25 minutes or until bubbly. Buffet-style bubbling is the goal here. You want a cheesy crust on top that says, “I’m ready to party!”

Common Mistakes to Avoid
You could consider this section your friendly guide to avoiding kitchen disasters. Trust me, I’ve made nearly all of these mistakes so you don’t have to.
- Thinking you don’t need to preheat the oven. Rookie mistake. Seriously, this isn’t your college microwave meal.
- Skimping on the cheese. Why would you want that? More cheese equals more happiness. This isn’t just a suggestion, it’s a lifestyle.
- Neglecting to mix the ingredients thoroughly. Lumpy meatloaf is a gateway to disappointment. Mix it like you mean it, folks.
- Not letting the cheese sauce thicken. This is the glue that holds your dreamy casserole together. If it’s watery, you just made an uncooked pasta swim.
- Forgetting to grease your baking dish. Everybody hates a stuck casserole. It’s the worst breakup ever.
Alternatives & Substitutions
Sometimes life throws you a curveball, like realizing you’re out of breadcrumbs or don’t have any ground beef. No sweat, my kitchen warrior.
- Ground Turkey or Chicken: Swapping out ground beef for turkey or chicken gives a lighter option, but who are we kidding? We want to live life fully, right?
- Gluten-Free Pasta & Breadcrumbs: For those avoiding gluten, there are fabulous alternatives. Check out brown rice pasta or gluten-free breadcrumbs. You do you, boo.
- Different Cheeses: Go wild with mozzarella or pepper jack if you want to live on the edge with a spicy kick.
- Veggies: Feeling a tad healthy? Sneak some diced bell peppers or mushrooms into the beef mix. They’ll totally get along.
- No Egg: For a vegan version, ditch the egg and try a flax egg or extra breadcrumbs.
FAQ
Can I use margarine instead of butter? Well, technically yes, but why hurt your soul like that? Butter is BFFs with cheese.
How do I store leftovers? Plop it into a container and refrigerate for up to three days. It also reheats like a champ in the microwave.
Can I freeze this casserole? You sure can. Cover it tightly before freezing, and it’ll happily chill in there for about three months.
What if my cheese sauce is too thick? No sweat. Whisk in a splash of milk, and you’re golden, baby.
Can I add spices to the meatloaf mix? Why yes, my adventurous friend! Spice it up with Italian herbs or a dash of hot sauce. Go be the rock star you were born to be.
