Ingredients Needed for Prime Rib Mac & Cheese Bake

  • 3 cups cooked prime rib, thinly sliced or chopped
  • 3 cups elbow macaroni or small pasta shape
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 3 cups whole milk, warmed
  • 1 cup heavy cream
  • 1 teaspoon Dijon mustard
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and freshly ground black pepper, to taste
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded Gruyère cheese
  • 1/2 cup Parmesan cheese, grated
  • 1/2 cup panko breadcrumbs
  • 2 tablespoons unsalted butter, melted
  • 1 tablespoon fresh parsley, chopped (optional)

Steps to Prepare Prime Rib Mac & Cheese Bake

  1. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
  2. In a large pot, cook the pasta in salted boiling water until al dente. Once done, drain and set aside.
  3. In a large saucepan over medium heat, melt the 3 tablespoons of butter. Whisk in the flour and let it cook for 1-2 minutes.
  4. Gradually add the warmed milk and heavy cream while stirring, until the mixture thickens, which should take about 5-7 minutes.
  5. Mix in the Dijon mustard, garlic powder, onion powder, salt, and pepper. Remove the saucepan from heat and stir in the cheddar, Gruyère, and half of the Parmesan cheese, mixing until everything is well melted.
  6. In a large bowl, gently fold the cooked pasta and chopped prime rib into the cheese sauce until everything is well combined.
  7. Spread the mixture evenly into the prepared baking dish.
  8. In a small bowl, combine the panko breadcrumbs with the melted butter and sprinkle this mixture on top of the pasta. Add the remaining Parmesan cheese over it.
  9. Bake in the oven for 25-30 minutes, or until the top is golden brown and bubbling.
  10. Let it sit for about 5-10 minutes before serving, garnishing with parsley if desired.

How to Serve Prime Rib Mac & Cheese Bake

Serve this Prime Rib Mac & Cheese Bake hot from the oven for the best experience. Pair it with a simple side salad or some roasted vegetables to balance the richness of the dish. The creamy cheese and savory meat make it an excellent main course, perfect for family gatherings or a cozy dinner with friends.

How to Store Prime Rib Mac & Cheese Bake

If you have leftovers, they can be easily stored for later enjoyment. Allow the bake to cool completely, then cover it tightly with plastic wrap or aluminum foil.

Tips for Perfect Prime Rib Mac & Cheese Bake Every Time

For a consistently delicious Prime Rib Mac & Cheese Bake, consider using high-quality cheddar and Gruyère cheese for a richer flavor profile. Make sure not to overcook the pasta; al dente is best as it will continue cooking while baking. Adjust the seasoning to your taste, and feel free to add a dash of hot sauce or a pinch of cayenne if you want to spice things up a bit. Lastly, allow it to rest after baking; this helps the cheese to set and makes serving easier.

Variations and Add-In Ideas

Get creative with your Prime Rib Mac & Cheese Bake by adding in different ingredients. Chopped mushrooms or fresh spinach are great ways to boost the nutrient profile. You could also swap the prime rib for cooked chicken or turkey for a different protein option. Experiment with different cheese varieties, like pepper jack for a bit of heat or mozzarella for extra stretchiness. Whatever you choose, this dish is versatile and can easily adapt to your family’s preferences.
