I usually make my baked macaroni and cheese for the holidays when I’m serving a crowd, but this simplified version is satisfying enough to serve dinner party guests all year long. 

Why You’ll Love It

  • While most recipes tend to use breadcrumbs as a topping, my version uses crushed cheese snack crackers instead. The extra layer of cheese flavor makes it completely indulgent.
  • This recipe is perfect for beginners! There are no fancy techniques required.
  • Homemade mac and cheese is the ideal side dish and this recipe is convenient enough to be your go-to recipe for year round gatherings.
  • Easily feed a crowd when you double or triple the recipe to make a large batch for family and friends, or ladies luncheons.
  • The way the sour cream, mayo and cheese come together during baking makes this velvety smooth and classic comfort food.

PARTY TIP: Use mini crocks to bake individual servings when you host a party.

Ingredients & Substitutions

  • Elbow macaroni. Elbows are the traditional shape for macaroni and cheese, but you can use any small pasta such as shells, penne, or rotini. I always use whole wheat pasta for more fiber and nutrition, but you can use regular or gluten-free pasta if you prefer.
  • Mayonnaise. I use Duke’s but you can use your favorite brand. Hellman’s is my second choice.
  • Sour cream. This adds creaminess and tanginess to the mixture. Try substituting with plain Greek yogurt too.
  • Sharp cheddar cheese. Use traditional orange cheddar or white cheddar, but you must shred it yourself. You can also use a combination of both, or add other varieties such as mozzarella, Monterey Jack, or Parmesan cheese. 
  • Cheesy crackers. You can use any brand but the most popular and easy to find are Cheese Nips or Cheez-Its. Another alternative is to use Ritz crackers, bread crumbs or panko, drizzle with a little butter and cook until golden brown.  

PARTY TIP: If using orange cheddar cheese, I suggest using the orange crackers. If using white cheddar cheese, use the Cheez-It white cheddar crackers. This way the layers of flavor are consistent.

How to Make It

  1. Cook the pasta in a large pot until al dente.
  2. Combine the mayonnaise, sour cream and pasta together in a large bowl, then stir in the cheese. 
  3. Transfer to a large baking dish, sprinkle with crushed crackers, and bake until cooked through.

Expert Tips

  • Make sure you salt the water for boiling the noodles.
  • Cook the pasta al dente, or a bit undercooked, to prevent it from getting mushy. Do not rinse the pasta! 
  • Allow the mayonnaise and sour cream to come to room temperature for about 30 minutes so it mixes well and cooks evenly.
  • Full fat mayonnaise and sour cream will result in a richer and creamier dish, however you can use the light versions too, if you wish.
  • Do not use low fat cheese for this; it’s the star ingredient! And always start with a block and shred it yourself so it melts perfectly.

Make Ahead

Prepare this ahead by following the instructions all the way except adding the crackers on top. Cover with foil and refrigerate. When ready to bake, remove from the fridge and top it with the crackers. Let the dish come to room temperature before placing it into a hot oven. Or, simply add the casserole into a cold oven and let it preheat with the oven. Cook as directed.
