Adult Macaroni and Cheese

Introduction

This adult mac and cheese trades the bright orange of boxed versions for a silky, multitextured sauce built from four cheeses—Fontina, Gruyère, mascarpone, and cream cheese—finished with butter folded in stages. The result is rich without being heavy, and it comes together in about 25 minutes. Serve it as a weeknight dinner, a side to roasted chicken, or a make-ahead lunch that reheats smoothly.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 15 minutes
• Total Time: 25 minutes
• Servings: 4

Ingredients

• ½ pound (227 g) elbow macaroni
• 6 ounces (170 g) heavy cream
• ½ tsp (2.5 ml) kosher salt, plus more for the water
• ½ cup (60 g / 2.1 oz) grated Fontina
• ½ cup (60 g / 2.1 oz) grated Gruyere
• ½ cup (150 g / 5.3 oz) mascarpone cheese
• ½ cup (150 g / 5.3 oz) cream cheese
• 4 thin slices Swiss cheese, julienned
• 1¼ sticks (150 g / 5.3 oz) unsalted butter, divided
• 2 tbsp (30 ml) all-purpose flour
• 1 tsp (5 ml) tabasco sauce

Instructions

1. In a gallon (~3.8 L) of salted boiling water, cook macaroni to al dente. Strain into a colander and rinse with cold water.
2. While pasta is cooking, in a heavy saucepan, melt 2 tbsp butter over medium heat. Once bubbling ceases, whisk in flour and cook, whisking continuously, until blonde.
3. Add remaining ingredients except butter. Once cheese is melted and sauce is smooth, add 1 tbsp butter, whisking continuously until melted. Repeat until all butter has been used.
4. Gently fold in macaroni and serve warm.

Variations

Smoked paprika and thyme: Add ½ tsp smoked paprika and a pinch of fresh thyme leaves to the finished sauce for a subtle earthiness that complements the cheese without overpowering it.

Truffle oil finish: Drizzle 1 tsp of truffle oil over each serving just before eating for a luxurious umami note that doesn’t require changing any main ingredients.

Crispy breadcrumb topping: Toss ½ cup panko with 2 tbsp melted butter and a pinch of salt; spread on top of the finished dish and broil for 2 minutes until golden. This adds textural contrast to the creamy sauce.

Mushroom and sage: Sauté 4 oz sliced cremini mushrooms and 3–4 sage leaves in 1 tbsp butter before building the sauce, then fold them in with the pasta. The mushroom umami deepens the cheese flavors.

White cheddar swap: Replace the Fontina and Gruyère with 1 cup grated sharp white cheddar for a brighter, more assertive cheese flavor.

Tips for Success

Watch the roux closely. Once you whisk in the flour, cook it for only 1–2 minutes—you want a pale blonde color, not brown. Overcooking it will make the sauce taste nutty and slightly bitter.

Add butter in small pieces, not all at once. The recipe calls for folding in 1 tbsp at a time because cold butter whisked into a hot sauce creates an emulsion that thickens and smooths the texture. If you dump it all in, you risk a greasy sauce.

Keep the cheese off the heat until the last step. Add all the cheeses and cream to the saucepan, then turn the heat down slightly and stir gently until melted. If the pan is too hot, the dairy can break and curdle.

Rinse the hot pasta with cold water. This stops carryover cooking and prevents the macaroni from clumping when you fold it into the sauce. Don’t skip this step.

Serve immediately. Mac and cheese firms up as it cools. If you need to hold it, keep the pot on very low heat and cover it; reheat in the oven if you’ve made it ahead.

Storage and Reheating

To reheat, transfer to a baking dish, cover with foil, and warm in a 325°F oven for 15–20 minutes until heated through. If the sauce seems dry, add a splash of heavy cream or milk and stir well before heating. You can also reheat individual portions in a microwave at 50% power for 1–2 minutes, stirring halfway through.

FAQ

Can I make this ahead and bake it like a casserole?

You can assemble it a few hours ahead, but don’t bake it—the pasta will overcook and turn mushy. Make the full dish, cool it to room temperature, refrigerate it covered, and reheat gently in the oven as described above.

What if the sauce breaks or looks grainy?

This usually happens if the heat was too high when the cheese was melting. Remove the pan from heat immediately, whisk in a splash of cold heavy cream or milk to cool it down slightly, and stir gently until smooth again.

Can I use a different pasta shape?

Yes. Penne, fusilli, or small shells all work well and hold sauce similarly to elbow macaroni. Avoid very small shapes like ditalini, which disappear into the cheese.

Is there a substitute for mascarpone or cream cheese?

Mascarpone adds richness and body; if you don’t have it, use an extra ¼ cup of cream cheese or ¼ cup of crème fraîche in its place. The sauce will be slightly less luxurious but still creamy.
