Ingredients
  

  • 12 oz penne pasta
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 6 cloves garlic minced
  • 1 ½ cups heavy cream
  • 1 cup whole milk
  • ½ cup grated Parmesan cheese
  • ¼ tsp crushed red pepper flakes optional
  • Salt and black pepper to taste
  • Fresh parsley chopped (for garnish)
  • Lemon juice optional, for balance

Instructions
 

  • Step 1: Cook the Pasta
    Boil salted water and cook the penne until al dente. Reserve ½ cup of pasta water before draining.
  • Step 2: Sauté Garlic
    In a large skillet, melt butter and olive oil over medium heat. Add garlic and cook for 1–2 minutes until fragrant—don’t let it brown.
  • Step 3: Make the Sauce
    Pour in cream and milk. Whisk well and let it simmer gently until slightly thickened, about 5–7 minutes.
  • Step 4: Add Cheese
    Stir in grated Parmesan and red pepper flakes if using. Season with salt and pepper to taste.
  • Step 5: Combine with Pasta
    Toss the cooked penne directly into the sauce. Add a splash of reserved pasta water if it needs loosening.
  • Step 6: Garnish and Serve
    Top with parsley and a squeeze of lemon juice for brightness. Serve hot with extra Parmesan.

Notes

Chef’s Secret Tips

  • Infuse the Garlic: Let the minced garlic gently sizzle in butter over low heat for 1–2 minutes—don’t rush it. That slow sauté builds a rich, aromatic base.
  • Reserve Pasta Water: Save ½ cup of the pasta cooking water before draining. A splash of it helps loosen and silk up the sauce if it thickens too much.
  • Use Fresh Parmesan: Grate it yourself. Pre-shredded cheese has anti-caking agents that can affect the sauce’s smoothness.
  • Finish with Lemon Zest: A pinch of lemon zest right before serving brightens up the entire dish and balances the richness.
  • Serve Immediately: Creamy garlic pasta is best hot off the stove. If you need to reheat, do it gently with a splash of milk or cream to revive the sauce.
