Step-by-Step Instructions

1. Cook the Pasta

• Cook macaroni according to package directions until al dente (1–2 minutes less than directed). Drain and set aside.
• Shortcut: Use 4–5 cups leftover mac and cheese! Skip to step 3.

2. Make the Cheese Sauce

• In a saucepan, melt butter over medium heat. Whisk in flour; cook 1 minute.
• Gradually whisk in warm milk until smooth. Simmer 2–3 minutes until thickened.
• Reduce heat to low. Stir in cheeses, mustard, cayenne, salt, and pepper until melted.
• Fold in cooked macaroni. Spread evenly in a greased 9×13-inch baking dish.

3. Prepare the Meatloaf Mixture

• In a large bowl, combine ground beef, breadcrumbs, milk, egg, onion, garlic, Worcestershire, ketchup, thyme, salt, and pepper. Mix gently with your hands or a fork—do not overmix.

4. Assemble the Casserole

• Spoon the meatloaf mixture over the mac and cheese layer. Press gently to form an even layer.
• In a small bowl, mix ketchup, brown sugar, and vinegar. Spread evenly over the meatloaf.

5. Bake to Perfection

• Bake at 375°F (190°C) for 40–45 minutes, until the meatloaf is cooked through (160°F internal temp) and the glaze is bubbly.
• Optional: Broil for 2–3 minutes at the end for a caramelized top.

6. Rest & Serve

• Let rest 10 minutes before slicing. This helps layers set for cleaner cuts.
• Serve with a simple green salad or steamed green beans.

Pro Tips for Perfect Casserole Every Time

• Al Dente Pasta: Prevents mushiness when baked.
• Freshly Shred Cheese: Pre-shredded cheese contains anti-caking agents that make sauce grainy.
• Don’t Overmix Meatloaf: Keeps it tender, not tough.
• Use a Meat Thermometer: Ensures safe doneness without overcooking.
• Make-Ahead: Assemble (unbaked) up to 24 hours ahead. Cover and refrigerate; add 5–10 minutes to bake time.
• Freezer-Friendly: Bake, cool, wrap tightly, and freeze for up to 2 months. Reheat at 350°F until hot.

Creative Variations for Every Diet & Craving

1. Gluten-Free: Use GF pasta, GF breadcrumbs, and tamari instead of Worcestershire.
2. Dairy-Free: Use dairy-free cheese shreds, plant-based milk, and vegan butter.
3. Keto/Low-Carb: Swap pasta for cauliflower rice; use almond flour in meatloaf.
4. Turkey or Plant-Based: Substitute ground turkey, chicken, or lentils for beef.
5. Loaded Version: Add cooked bacon, diced bell peppers, or spinach to the mac layer.
6. Breakfast Casserole: Use breakfast sausage + hash browns + cheddar base.

Frequently Asked Questions (FAQs)

Q: Can I use boxed mac and cheese?
A: Yes! Use 2 boxes (prepared as directed) for the base. Reduce added cheese in the recipe.

Q: Why is my meatloaf dry?
A: Likely causes: Overmixing, using lean beef (90/10), or overbaking. Use 85/15 beef and don’t overcook.

Q: Can I make this in a slow cooker?
A: Not ideal—the pasta will become mushy. Stick to the oven for best texture.

Q: How do I store leftovers?
A: Keep in an airtight container in the fridge for up to 4 days. Reheat in the oven or microwave.

Q: Can I add veggies to the meatloaf?
A: Yes! Sauté ½ cup finely diced carrots, zucchini, or mushrooms with the onions first.
