Truffled, Mustardy Mac & Cheese


Test Kitchen-Approved

Author Notes: Mustard is the secret ingredient that your mac and cheese has been missing. I decided to work in Maille's uber-lux truffle and chablis white wine version into this savory, mustardy mac and cheese. Here, you'll make a roux before adding cheese into the mixture—it creates a cohesive sauce that coats the pasta, letting the whole thing slide easily right into a casserole dish to pop into the oven.

Makes: one 9 x 13 casserole dish

Ingredients

  • 1 pound dried pasta, preferably penne rigate or cavatappi
  • 1/2 cup (1 stick) unsalted butter
  • 2 shallots, finely chopped
  • 2 cloves garlic, finely chopped
  • 1/3 cup flour
  • 1 teaspoon kosher salt
  • 3 cups milk
  • 1 tablespoon chopped herbs like rosemary and thyme (optional)
  • 1/4 to 1/2 cup dry white wine, like a white Burgundy
  • 2 to 3 tablespoons high quality mustard, preferably truffled
  • 3 cups grated Comte or Gruyere cheese
  • 1/2 cup shredded Parmesan, divided
  • 3/4 cup breadcrumbs, preferably panko
  • Flaky sea salt, to garnish

Directions

  1. Preheat oven to 350° F. Lightly grease or spray a 9- by 13-inch (3-quart) baking dish. (If you care to warm your milk before adding it, which can help it incorporate into the sauce later, now’s the time to place it in a large glass bowl and put it on a burner while the oven heats up.)
  2. Fill a large pot with water and bring to a boil. Add the pasta and cook until very al dente (about 3 minutes shy of how you'd cook it normally for al dente doneness). Rinse under cold water to stop the cooking, drain, and set aside.
  3. In a medium saucepan, melt the butter over medium heat. Add the chopped shallots (they’ll be swimming in butter) and let them cook until translucent but not browned at all, about 5 minutes.
  4. Add the chopped garlic and cook for 30 seconds, stirring constantly. Whisk in the flour and salt and cook, whisking constantly, for 1 minute.
  5. Add the milk and continue to whisk constantly. Bring the mixture to a boil, then turn it down to low and continue to cook while you stir it until the mixture thickens, about 5 minutes. Add the herbs, wine, and mustard to the sauce, and continue to stir for 30 seconds. Then, add all the cheese except for 1/4 cup of the Parmesan. Stir until the cheese melts, then remove from the heat. Add the pasta to the cheese sauce.
  6. Pour the mixture into your prepared pan. Top with the remaining 1/4 cup Parmesan cheese and the breadcrumbs.
  7. Bake for 20 to 30 minutes, or until golden and bubbling on top. Depending on the size of your pasta, it will take more or less time.
  8. Remove from the oven and transfer to a cooling rack. Cut into squares, garnish with flaky sea salt and extra herbs if you'd like, and then serve while still piping hot!

Replace the milk with evaporated Milk. No Flour needed if you do that and the result is significantly more creamy. I also use 2 TBSP of Habenero Crema.

If I want to make this ahead of time and reheat, at what temperature and for how long should I reheat it?

Try 200-250F at 20 minutes to reheat it - or you could assemble everything ahead of time, store in the fridge, and then bake it off day of!

Hi<br />I can't get that particular mustard in Canada. Would you suggest substituting with Dijon and truffle salt or truffle oil ?<br />Thanks !

Hi Carolyn! I'd suggest stirring in a little truffle oil to some dijon mustard before adding it to the dairy mixture. You'd probably want to go light on the oil at first so it's not too overpowering. Let me know how it turns out!
