Step-by-Step Instructions
Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a deep 9 × 13-inch baking dish.
Set the prepared dish aside while you make the beef and macaroni and cheese.
Cook the Macaroni
Bring a large pot of generously salted water to a boil.
Add the elbow macaroni and cook according to the package instructions until al dente.
The pasta should still have a little firmness because it will continue cooking in the oven.
Drain the macaroni thoroughly.
Do not rinse it, as the natural starches help the cheese sauce cling to the pasta.
Set aside.
Prepare the Ground Beef
Heat a large skillet over medium-high heat.
Add the ground beef and chopped onion.
Cook for approximately 6–8 minutes, breaking the beef apart with a wooden spoon or spatula as it cooks.
Continue until the beef is fully browned and the onion has softened.
Add the minced garlic, paprika, salt, and black pepper.
Cook for another 1 minute, stirring frequently, until the garlic becomes fragrant.
Drain any excess fat from the skillet.
Remove the beef mixture from the heat and set aside.
Make the Cheese Sauce
Place a large saucepan over medium heat.
Add the butter and allow it to melt completely.
Whisk in the flour.
Cook the butter-and-flour mixture for approximately 1–2 minutes, whisking constantly. This creates the roux and removes the raw flour taste.
Gradually pour in the warmed milk while whisking continuously.
Continue whisking until the mixture becomes smooth.
Cook for approximately 4–6 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
Add the Cheese
Reduce the heat to low.
Add approximately 2 cups of the shredded cheddar cheese, a handful at a time, whisking after each addition until melted and smooth.
Add the mozzarella and dry mustard powder.
Season with additional salt and black pepper to taste.
Stir until the cheese sauce is creamy and completely smooth.
Avoid boiling the sauce after adding the cheese, as excessive heat can cause the sauce to become grainy.
Combine the Macaroni and Cheese Sauce
Add the drained macaroni to the cheese sauce.
Stir gently until every piece of pasta is thoroughly coated.
The macaroni should look creamy and generously covered with cheese sauce.
Assemble the First Layer
Spoon approximately half of the macaroni and cheese into the prepared baking dish.
Spread it into an even layer.
Use the back of a spoon or spatula to gently level the surface.
Add the Beef Layer
Spread the seasoned ground beef evenly over the macaroni and cheese.
Make sure the beef reaches close to the edges so that every serving contains a good balance of beef and pasta.
Add the Remaining Mac & Cheese
Spoon the remaining macaroni and cheese over the beef layer.
Spread it gently and evenly across the entire surface.
Do not press down too firmly, as you want to preserve the creamy texture of the pasta.
Add the Cheese Topping
Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
This creates a rich, golden, bubbling cheese layer during baking.
Bake
Place the casserole in the preheated oven.
Bake uncovered for approximately 25–30 minutes, or until the casserole is hot throughout and the cheese on top is melted and bubbling.
For a more deeply golden top, switch the oven to broil for approximately 1–2 minutes at the end.
Watch carefully because the cheese can brown very quickly under the broiler.
Rest and Garnish
Remove the casserole from the oven.
Allow it to rest for approximately 5–10 minutes before serving.
This gives the layers time to settle and makes the casserole easier to portion.
Sprinkle with freshly chopped parsley.
Serve hot.
Best Tips for Perfect Mac & Cheese Casserole
Cook the pasta al dente: Slightly firm pasta holds its shape better during baking and prevents the finished casserole from becoming mushy.
Warm the milk: Using warm milk helps the cheese sauce come together more smoothly and reduces the chance of lumps.
Whisk the roux continuously: This creates a smooth foundation for the cheese sauce.
Grate your own cheese: Freshly grated cheese generally melts more smoothly than many pre-shredded varieties.
Do not boil the cheese sauce: High heat after adding the cheese can cause the sauce to separate or become grainy.
Drain the beef well: Removing excess fat keeps the casserole rich without making it greasy.
Let the casserole rest: A short resting period makes it easier to serve clean layers without sacrificing the creamy texture.
Best Ingredient Options
Ground beef: Lean ground beef works particularly well because it provides plenty of savory flavor without excessive grease.
Cheddar: Sharp cheddar gives the casserole a stronger cheese flavor. Medium or mild cheddar can be used for a softer taste.
Mozzarella: Mozzarella adds excellent meltability and creates a stretchy cheese texture.
Milk: Whole milk produces the richest cheese sauce. Lower-fat milk can work, but the sauce may be slightly less creamy.
Macaroni: Elbow macaroni is classic, but shells, cavatappi, rotini, or penne can also hold the cheese sauce beautifully.
Recipe Variations
Spicy Beef Mac & Cheese
Add ½ teaspoon crushed red pepper flakes or a diced jalapeño to the beef mixture for extra heat.
BBQ Beef Mac & Cheese
Stir 2–3 tablespoons of barbecue sauce into the cooked beef before layering.
Mushroom Beef Casserole
Sauté sliced mushrooms with the onions before adding the ground beef for a deeper savory flavor.
Extra-Cheesy Version
Add an additional ½ cup of cheddar or mozzarella between the layers for an even cheesier casserole.
Italian-Style Variation
Replace the paprika with Italian seasoning and add a small amount of Parmesan to the cheese sauce.
Vegetable Beef Mac & Cheese
Add sautéed bell peppers, mushrooms, zucchini, or spinach to the beef mixture for extra texture and flavor.
What to Serve With This Casserole
Because this casserole is hearty and filling, simple side dishes work best.
Serve it with a crisp green salad dressed with a light vinaigrette to provide freshness alongside the rich cheese sauce.
Steamed broccoli, roasted green beans, or sautéed vegetables also make excellent additions.
For a classic comfort-food dinner, serve it with warm garlic bread or crusty bread.
A simple fruit salad can also provide a refreshing finish after the rich casserole.
Make-Ahead Instructions
This casserole can be assembled ahead of time.
Prepare the beef and macaroni and cheese according to the recipe.
Assemble the layers in the baking dish, but do not bake.
Allow the casserole to cool if the ingredients are still very hot, then cover tightly and refrigerate for up to 24 hours.
When ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for approximately 20–30 minutes.
Bake at 375°F (190°C) until hot throughout and bubbling.
Because the casserole starts cold, it may require an additional 10–15 minutes of baking time.
Storage
Allow leftover casserole to cool before transferring it to an airtight container.
Refrigerate for up to 3–4 days.
Individual portions are convenient for quick lunches or dinners.
Reheating
For the best texture, reheat individual portions in the oven.
Place a serving in an oven-safe dish, cover loosely with foil, and heat at 350°F (175°C) until warmed through.
For a faster option, microwave individual portions in short intervals, stirring or rotating if necessary.
If the macaroni seems dry after refrigeration, add a small splash of milk before reheating.
Freezing
This casserole can be frozen, although creamy cheese sauces may become slightly less smooth after thawing.
For best results, freeze the casserole before baking if you are intentionally preparing it as a freezer meal.
Wrap the assembled casserole tightly with freezer-safe wrapping and aluminum foil.
Freeze for up to 2 months.
Thaw overnight in the refrigerator before baking.
Alternatively, freeze cooled individual portions in airtight freezer-safe containers.
Common Mistakes to Avoid
Overcooking the macaroni: Pasta that is already very soft can become mushy after baking.
Using cold milk: Cold milk can make the roux harder to incorporate smoothly.
Adding cheese over high heat: Excessive heat can cause the cheese sauce to separate.
Skipping the beef draining step: Excess grease can make the finished casserole oily.
Adding too much flour: An overly thick roux can produce a heavy cheese sauce. Measure carefully.
Overbaking: Bake only until the casserole is hot and the cheese is melted and bubbling.
Cutting immediately: Give the casserole several minutes to rest before serving.

Frequently Asked Questions
Can I use a different pasta shape?
Yes. Shells, cavatappi, rotini, and penne are all good alternatives. Choose a shape with plenty of ridges or curves so it can hold the creamy cheese sauce.
Can I use pre-shredded cheese?
Yes, but freshly grated cheese generally melts more smoothly. If using packaged shredded cheese, choose a variety that melts well.
Can I make this casserole with ground turkey?
Yes. Ground turkey can replace the beef. The flavor will be lighter, but the cheesy sauce and seasonings still work beautifully.
Why did my cheese sauce become grainy?
This is usually caused by excessive heat or overheating the cheese. Once the cheese is added, keep the sauce over low heat and stir gently until smooth.
Can I make it ahead?
Yes. Assemble the casserole up to 24 hours ahead and refrigerate it covered. Add some extra baking time because the casserole will be cold when it goes into the oven.
Can I add vegetables?
Absolutely. Sautéed mushrooms, bell peppers, zucchini, spinach, or broccoli can all be incorporated into the beef layer.
How do I make the top extra golden?
After baking, switch the oven to broil for approximately 1–2 minutes. Watch it continuously because the cheese can brown very quickly.
