Southern Baked Mac and Cheese with Breadcrumbs

This isn’t just any mac and cheese—this is the kind that makes grown adults weak in the knees and turns family dinners into competitive eating contests.

We’re talking about a luxurious gruyere and white cheddar blend that creates the most ridiculously creamy sauce you’ve ever encountered, all nestled around perfectly cooked cavatappi pasta.

The secret weapon here is that golden, buttery breadcrumb topping that adds the perfect textural contrast to all that gooey cheese goodness underneath.

This recipe starts with a proper roux and bechamel sauce, which might sound fancy but is basically just your ticket to mac and cheese that doesn’t break or turn grainy like those boxed disasters.

The optional truffle oil in those breadcrumbs will have people convinced you went to culinary school, when really you just followed some very good directions.

Fair warning: making this will result in you becoming the designated mac and cheese person for every potluck, holiday, and “casual” dinner party from now until forever.

Ingredients

For the Pasta

• 1 lb cavatappi pasta

Mac and Cheese Sauce

• 6 tablespoons butter
• 6 tablespoons all-purpose flour
• 4 cups whole milk – warmed up in the microwave
• 1 cup diced yellow onions (optional)
• 16 oz gruyere cheese – shredded
• 8 oz white cheddar cheese – shredded
• Salt and pepper to taste

Breadcrumb Topping

• 5 tablespoons butter
• 2 cups breadcrumbs – use panko breadcrumbs for a flakier crust

Optional Spices

• ½ teaspoon cayenne powder – add more or less depending on preference
• 2 teaspoons truffle oil

Instructions

Preparation

1. 1 Preheat your oven to 375°F (190°C) and position the rack in the center. This temperature ensures even browning of the breadcrumbs without overcooking the cheese sauce.
2. 2 Boil the cavatappi pasta according to package directions but drain it 1-2 minutes early. The pasta will continue cooking during the baking process, and this prevents the final dish from becoming mushy. You want the pasta to still have a slight bite when you drain it.

Mac and Cheese Sauce

1. 3 Make the roux by melting 6 tablespoons butter in a heavy-bottomed pot over medium heat. Once completely melted, add the flour and stir quickly using a flat spatula or whisk. Scrape the bottom and sides continuously for 3 minutes. The roux should stay a pale yellow color—if it starts browning, lower your heat immediately.
2. 4 Create the bechamel sauce by slowly drizzling the warm milk into the pot while whisking vigorously. Add the diced onions at this time if using. The key here is patience—add the milk gradually to prevent lumps from forming. Stir continuously for 5-7 minutes until the mixture thickens enough to coat the back of a spoon.
3. 5 Add the cheese by removing the pot from heat and stirring in ¾ of both the gruyere and cheddar cheese. Reserve the remaining cheese for topping. Stir until completely melted and smooth. Taste for seasoning—you may not need salt depending on your cheese’s saltiness. Add cayenne powder now if you want a subtle heat.

Assembly

1. 6 Combine the cooked pasta with the cheese sauce in your casserole dish, mixing thoroughly until every piece of pasta is coated. Top with the remaining ¼ of shredded cheese, distributing it evenly across the surface.

Breadcrumb Topping

1. 7 Prepare the topping by melting 5 tablespoons butter in a large skillet over medium heat. Add the breadcrumbs and toss until evenly coated and lightly golden, about 2-3 minutes. Remove from heat and drizzle in the truffle oil if using, tossing to combine.
2. 8 Spread the buttered breadcrumbs evenly over the cheese layer, creating a uniform coating that will brown beautifully.

Final Baking

1. 9 Bake on the center rack for 30-35 minutes until the top is golden brown and the edges are bubbling. If the breadcrumbs brown too quickly, tent with aluminum foil and reduce temperature to 350°F (175°C) for the remaining time.

Recommended Equipment and Kitchen Tools

Essential Tools (for best results)

Pro Tips and Troubleshooting

Professional Techniques

Always warm your milk before adding to the roux—cold milk causes lumps that are nearly impossible to smooth out. Grate cheese fresh rather than using pre-shredded varieties, which contain anti-caking agents that prevent smooth melting. Remove the pot from heat before adding cheese to prevent the proteins from seizing and creating a grainy texture.

Common Mistake Prevention

Never let your roux brown beyond pale yellow, as darker roux will give your sauce an unpleasant bitter flavor. If your sauce breaks or becomes grainy, remove from heat immediately and whisk in a tablespoon of cold butter to bring it back together. Don’t overbake—the edges should bubble but the center should still have some give when gently shaken.

Storage and Reheating

Refrigerate leftovers for up to 4 days covered tightly. Reheat individual portions in the microwave at 50% power, stirring every 30 seconds. For larger portions, reheat covered in a 325°F (165°C) oven for 20-25 minutes, adding a splash of milk if it seems dry.

Make-Ahead Strategy

Assemble completely up to the baking step, cover tightly, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time if cooking from cold. The breadcrumb topping can be prepared separately and stored for 2 days.

This Southern Baked Mac and Cheese with Breadcrumbs represents everything comfort food should be—rich, satisfying, and guaranteed to bring people together around the dinner table. The combination of proper technique and quality ingredients transforms a simple concept into something truly spectacular that’ll have everyone asking for seconds.
