👩‍🍳 How to Make It

Step 1: Get ready

Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with cooking spray or butter.

---

Step 2: Make the meatloaf mixture

In a large bowl, combine:

• Ground beef

• Breadcrumbs

• Milk

• Egg

• Chopped onion

• Minced garlic

• Salt, pepper, and Worcestershire sauce

Mix with your hands until just combined — don’t overmix, or the meatloaf will be tough.

---

Step 3: Press into the dish

Press the meatloaf mixture evenly into the bottom of your greased baking dish.
Spread 2 tablespoons of ketchup over the top of the meat.

---

Step 4: Partially bake the meatloaf

Bake the meatloaf layer for 15–20 minutes, until it’s starting to brown and has released some of its juices.

Skip this step? The meatloaf won’t be fully cooked by the time the mac and cheese is done. Don’t skip!

---

Step 5: Cook the pasta

While the meatloaf bakes, bring a pot of salted water to a boil.
Cook the elbow macaroni according to package directions until al dente (1 minute less than the package says — it will continue cooking in the oven).
Drain and set aside.

---

Step 6: Make the cheese sauce

In a large saucepan, melt butter over medium heat.
Whisk in the flour and cook for 1 minute until bubbly.

Slowly pour in the milk and heavy cream, whisking constantly to prevent lumps.
Cook for 3–5 minutes until the sauce thickens enough to coat the back of a spoon.

Remove from heat. Stir in:

• Cheddar cheese

• Mozzarella (or Monterey Jack)

• Parmesan cheese

• Salt, pepper, and paprika (if using)

Stir until the cheese is completely melted and the sauce is smooth.

---

Step 7: Combine pasta and cheese sauce

Add the cooked macaroni to the cheese sauce.
Stir until every piece of pasta is coated in that creamy, cheesy goodness.

---

Step 8: Assemble the casserole

Take the meatloaf layer out of the oven.
Spoon the mac and cheese evenly over the top of the meatloaf.

If you want extra cheesiness, sprinkle with additional shredded cheese on top.

---

Step 9: Bake again

Return the casserole to the oven.
Bake uncovered for 15–20 minutes, until the mac and cheese is bubbly and golden on top.

---

Step 10: Rest and serve

Let the casserole rest for 10 minutes before serving.
(This helps it set so you can get clean slices.)

Garnish with fresh parsley if desired.
Serve hot.

---

🍴 What to Serve With It

• A simple green salad with vinaigrette (something fresh to cut through the richness)

• Roasted green beans or broccoli

• Steamed peas

• Just a big fork — it’s a meal all by itself!

❓ Quick Answers

Q: Why bake the meatloaf first?
The meatloaf needs more time to cook than the mac and cheese. Pre-baking ensures both layers are perfectly done when the casserole comes out of the oven.

Q: Can I use leftover meatloaf?
Yes! Crumble leftover meatloaf into the bottom of the dish, then top with freshly made mac and cheese. Bake at 375°F for 15–20 minutes.

Q: Can I make this ahead of time?
Yes! Assemble the entire casserole (but don’t bake), cover, and refrigerate for up to 24 hours. When ready to eat, bake at 375°F for 25–30 minutes.

Q: Can I freeze it?
Yes! Freeze the unbaked casserole for up to 2 months. Thaw in the fridge overnight, then bake as directed (add 10–15 minutes if still cold).

Q: How long do leftovers last?
4–5 days in the fridge in a sealed container.

Q: My cheese sauce is grainy. What happened?
The heat was too high when you added the cheese. Always take the sauce off the heat before stirring in the cheese. Also, pre-shredded cheese has anti-caking agents that can cause graininess — shredding your own works best.
