  • 1 lb steak (sirloin or ribeye) grilled and sliced
  • 1 cup shredded cheddar cheese sharp and melty
  • 1 cup shredded Monterey Jack cheese creamy and smooth
  • 2 cups milk whole milk works best
  • 4 tbsp butter for a rich roux base
  • 4 tbsp all-purpose flour thickens the cheese sauce
  • 1 tsp garlic powder adds depth of flavor
  • 1 tsp onion powder rounds out the seasoning
  • salt and pepper to taste
  • 1/2 cup fresh parsley chopped, bright and fresh for chimichurri
  • 2 tbsp fresh oregano chopped, herby and aromatic
  • 2 tsp red pepper flakes for a gentle heat
  • 1/2 cup olive oil base for chimichurri sauce
  • 1 tbsp lemon juice adds acidity and brightness

Instructions

Cook the Macaroni

  • Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente, usually about 7-8 minutes. Drain and set aside.

Grill and Slice the Steak

  • Preheat your grill or grill pan over medium-high heat. Season the steak generously with salt and pepper. Grill for about 4-5 minutes per side for medium-rare, or adjust timing to your preferred doneness. Let the steak rest for 5 minutes before slicing it thinly against the grain.

Make the Chimichurri Sauce

  • In a mixing bowl, combine chopped parsley, fresh oregano, red pepper flakes, olive oil, and lemon juice. Stir well and season with salt and pepper to taste.

Prepare the Cheese Sauce

  • In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for about 1-2 minutes, stirring constantly to form a roux. Slowly whisk in the milk, making sure no lumps form. Add garlic powder, onion powder, salt, and pepper. Continue whisking until the sauce thickens, about 5-7 minutes.

Add the Cheese

  • Remove the saucepan from heat and stir in the shredded cheddar and Monterey Jack cheeses until melted and smooth.

Combine Pasta and Cheese Sauce

  • Add the cooked macaroni to the cheese sauce and stir until the pasta is well coated.

Assemble and Serve

  • Plate the mac and cheese, then top with sliced steak. Spoon generous amounts of chimichurri sauce over the steak for a burst of herbal brightness. Serve immediately and enjoy!
