What Is Million Dollar Mac and Cheese?

Million dollar mac and cheese is a classic American side dish. It’s like your favorite mac and cheese recipe, but better. It’s richer, cheesier, and creamier thanks to three kinds of cheese and a splash of milk.

Then it’s assembled in a casserole dish with an extra layer of cheese and sour cream in the middle for a lovely cheese pull when serving. The crispy panko topping also adds texture and makes it look particularly impressive.

Ingredients in bowls for mac and cheese recipe, arranged from top to bottom: pasta, Monterrey jack cheese, cheddar cheese, gruyere cheese, onion powder, garlic powder, dried parsley, flour, Panko Breadcrumbs, evaporated milk, sour cream, butter, whole milk, mustard, salt and pepper.

Recipe Ingredients

Cavatappi pasta and a crispy panko topping elevate this side dish to new heights. Scroll down to the recipe card for exact amounts.

  • Cavatappi Noodles: These look like swirly elbow macaroni noodles. You can use regular elbow macaroni if you prefer.
  • Unsalted Butter: Try to avoid salted butter because the cheese mixture is already quite salty.
  • All-Purpose Flour: Used to thicken the roux, to make the homemade cheese sauce.
  • Whole Milk: 2% works too, but you want the fat to create the best tasting sauce.
  • Evaporated Milk: Heavy cream is a great swap, if needed.
  • Dijon Mustard: Don’t use American mustard because the flavor is very sharp and tangy. If you do not have dijon mustard, swap it for 1 teaspoon dried mustard.
  • Seasonings: Garlic powder, onion powder, dried parsley, salt and pepper.
  • Cheddar Cheese: Go for extra-sharp or sharp cheddar cheese. White cheddar is also tasty!
  • Monterey Jack Cheese: It can be substituted for Colby Jack or Pepper Jack.
  • Gruyère Cheese: Feel free to replace it with Gouda or even more cheddar.
  • Sour Cream: Ricotta cheese will also work.

Topping

  • Breadcrumbs: Panko breadcrumbs will create the best crispy texture, but regular breadcrumbs work too.
  • Butter: Go for unsalted to keep things from getting too salty.

How to Make Mac and Cheese Casserole

The two secrets to any homemade macaroni and cheese recipe are properly cooked pasta and a creamy, smooth sauce. Scroll to the recipe card at bottom of the post for full detailed instructions. 

  • Boil: Cook the pasta according to the package directions minus one minute. Drain, rinse with cool water to prevent sticking and set aside.
  • Roux: Melt the butter in a large saucepan and mix in the flour to create a roux. Whisk in the milk and evaporated milk until smooth. Add the mustard and seasonings and simmer until thickened.
  • Cheese: Stir in the cheddar and Monterey Jack cheeses, until melted and smooth. Fold in the cooked macaroni.
  • Assemble: Pour half of the pasta mixture into the casserole dish. Sprinkle half of the Gruyere on top. Spread the sour cream on top. Add the remaining pasta and then sprinkle the remaining cheese over the top.
  • Topping: Combine the panko breadcrumbs with melted butter in a small bowl. Spread over the top.
  • Bake: Bake in preheated oven until hot and bubbly and the topping is a light golden brown.
  • Serve: Remove from the oven and let it cool for 5 minutes. Serve and enjoy.

Cook’s Tips

A few tips to ensure your mac and cheese recipe turns out perfectly!

  • Freshly Shredded Cheese: While it is easier to grab already shredded cheese, pre-shredded cheese has anti-caking agents that act as a thickener. So if you use pre-shredded cheese, it will overly thicken your cheese sauce. I highly recommend shredding your own cheese!
  • Don’t Over-Cook Pasta: Set a timer on your phone to remind yourself to remove the pasta as soon as it is al-dente. Over-cooking the noodles will lead to a mushy macaroni and cheese.
  • One-Pot: Use a large dutch-oven, or a cast-iron skillet, to prepare this recipe so you can go from stove-to-oven and reduce clean-up.
  • Make Ahead: Let the mac and cheese cool to room temperature once you transfer it to the casserole dish. Wrap it tightly with plastic wrap or foil and refrigerate for up to 24 hours. Let is set out at room temperature for 30 minutes before cooking. Then, top with breadcrumb mixture and bake as directed.

Variations To Try

If it’s already a “million dollar” recipe, why not add some truffle oil or lobster?

  • Leftover Cheeses: Shred all the leftover bits of melty cheese in your fridge and use them for this recipe. It’ll be a unique cheese mix!
  • Truffle: Drizzle 1 to 2 tablespoons of truffle oil over the casserole for an impressive truffle mac and cheese. You can whip up a batch of roasted mushrooms, dice them and stir them into the pasta.
  • Seafood: Elevate the dish by adding chunks of cooked buttery lobster, or crab meat, for a luxurious seafood twist.
  • Smoked: If you want your mac and cheese to have a wonderful smoky flavor, swap the gruyere cheese for smoked gouda.
  • Garlic: If you love garlic and want more garlic flavor, add 3 to 5 cloves minced garlic when you add the garlic powder.
  • Bacon: You can add cooked and chopped bacon to the pasta, as a topping, or both!

How To Store Leftovers

  • Fridge: Refrigerate it in an airtight container for up to 5 days. You can also cover the casserole dish with foil.
  • Reheat: Sprinkle a serving with 1/2 teaspoon milk and microwave in 30-second intervals, until warm. Or bake in the oven at 325°F, lightly covered with foil for 15 minutes, then uncovered for 5 minutes more.
