Ingredients

  • 4 ounces pasta cooked according to box (save 1 cup pasta water)
  • 6 ounces langostino tails thawed and drained
  • 2 1/2 tbsp. unsalted butter
  • 1 tbsp. all-purpose flour
  • 2 - 4 cloves garlic minced
  • 1/2 tsp. salt I use Diamond Crystal kosher salt
  • 1/4 tsp. ground black pepper
  • 3/4 cup half and half room temperature
  • 1/4 cup whole milk room temperature
  • 1 1/2 cups freshly grated Parmesan cheese from a block is best, divided
  • 1 tbsp. chopped chives or parsley for garnish optional

Instructions

  • In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 3 - 4 minutes.
  • Add garlic and whisk to combine. Season with half of the salt and pepper.
  • Slowly whisk in milk and half & half. (Start slowly, to allow milk/half and half to blend in as you're whisking. Don't dump it all in at once)
  • Whisk frequently over medium/medium low heat until sauce has thickened.
  • When sauce has reached desired consistency, remove from heat and whisk in 1 - 1 1/4 cups grated Parmesan. Add additional salt and pepper to taste.
  • If sauce is too thick, add a splash of pasta water to thin it. Add a ladle or two of sauce to cooked pasta and toss to coat noodles with sauce. Add pasta to bowls for serving.
  • Gently fold thawed and drained langostino tails into remaining sauce and ladle sauce over pasta.
  • Top with fresh parsley or chives and remaining grated Parmesan cheese.

Notes

If you like a little spice, add my Cajun seasoning blend to the sauce.
*Don't forget to save a cup of pasta water to thin the sauce, if needed.
