Instructions

Roast the Garlic

Preheat the oven to 400°F (200°C). Wrap the whole garlic bulb tightly in aluminum foil and roast for 30-35 minutes until golden and soft. Roasting transforms garlic’s sharpness into a rich, sweet, and mellow flavor perfect for the sauce. Once cooled, squeeze the caramelized cloves into a bowl, ready to be mashed.

Cook the Pasta

Bring a large pot of salted water to a rolling boil. Add your preferred pasta and cook until just al dente, following package instructions carefully. Reserving about 1 cup of starchy pasta water before draining will help adjust the sauce texture later, ensuring a creamy and smooth consistency.

Prepare the Garlic Paste

Heat olive oil in a medium saucepan over medium heat. Add the roasted garlic and mash it with a fork into a fragrant paste. Cooking for two minutes allows the garlic to meld with the oil and develops deeper flavor nuances for the sauce base.

Add the Heavy Cream

Pour in the heavy cream and stir to combine thoroughly with the garlic paste. Heat gently for 3-4 minutes without boiling to thicken and marry the flavors, creating a decadent, creamy foundation for the sauce.

Incorporate Lemon Elements

Stir in the freshly squeezed lemon juice and lemon zest. Season with salt and black pepper to taste. Cook for an additional 2 minutes to let the bright citrus flavors infuse the sauce, balancing the richness of the cream and garlic.

Mix in the Parmesan Cheese

Gradually add the grated Parmesan cheese, stirring continuously. This ensures the cheese melts evenly into the sauce, adding umami depth and forming a silky, cohesive texture that clings beautifully to the pasta.

Combine Pasta and Sauce

Add the cooked pasta directly to the sauce, tossing well to coat each piece evenly. If the sauce is too thick, drizzle in reserved pasta water a little at a time until you reach a luscious, smooth consistency that binds the pasta and sauce perfectly.

Garnish and Serve

Remove the pan from heat and sprinkle chopped fresh parsley over the top for a pop of color and fresh herbal brightness. Serve immediately for the best texture and flavor.

You Must Know

  • Roasting garlic mellows its pungency, making the sauce pleasantly sweet and less sharp.
  • Use freshly squeezed lemon juice and zest for best citrus flavor—not bottled lemon juice.
  • Starchy pasta water acts as a secret ingredient to perfectly thin and help the sauce adhere to pasta.

Storage Tips

Store leftover sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on low heat, adding a splash of milk or pasta water to loosen the sauce if needed.

Serving Suggestions

This creamy garlic lemon pasta is delightful served with a crisp green salad or crunchy garlic bread to add contrasting textures. Pair with chilled white wine such as Pinot Grigio to complement the citrus notes perfectly.

Professional Tips

  • For added protein, toss in grilled chicken, sautéed shrimp, or roasted vegetables when combining pasta and sauce.
  • Adjust seasoning carefully, adding salt after cheese to prevent oversalting.
  • Use fresh herbs like basil or thyme alongside parsley for extra aromatic layers.
