Step‑by‑Step Instructions for Creamy Roast Garlic and Lemon Pasta Sauce
Step 1: Roast the Garlic
Preheat your oven to 400°F (200°C). Take a whole bulb of garlic and wrap it tightly in aluminum foil. Place it in the oven for 30-35 minutes. You’ll know it’s ready when the cloves turn golden brown and feel soft to the touch. Let it cool before squeezing out the luscious garlic into a bowl.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil. Add your choice of pasta, such as spaghetti or penne, and cook according to the package instructions until it reaches al dente perfection. Just a few minutes before draining, be sure to reserve about 1 cup of the starchy pasta water for later use.
Step 3: Sauté the Garlic
In a medium saucepan, heat a generous drizzle of olive oil over medium heat. Once it’s shimmering, add the mashed roasted garlic and sauté for about 2 minutes, stirring frequently until fragrant. This step is vital for unlocking the full, comforting flavor in your creamy roast garlic and lemon pasta sauce.
Step 4: Add the Cream
Reduce the heat to low and pour in the heavy cream, stirring well to combine. Gently heat the mixture for 3-4 minutes, being careful not to bring it to a boil. You’ll want the sauce to warm through and begin thickening, transforming it into a rich base for your pasta.
Step 5: Incorporate the Lemon
Stir in the freshly squeezed lemon juice and zesty lemon zest into the creamy mixture. Season with salt and black pepper to taste, and let it simmer for another 2 minutes. The lemon will brighten the sauce while harmonizing with the roasted garlic, enhancing your creamy roast garlic and lemon pasta sauce.
Step 6: Blend in the Cheese
Gradually add the grated Parmesan cheese to the sauce, stirring continuously until fully melted and integrated. The cheese will create an even creamier texture, enriching the sauce’s overall flavor. It’s the perfect finishing touch to elevate your delicious pasta dish.
Step 7: Combine the Pasta and Sauce
Once the pasta is drained, add it directly to the saucepan with the creamy sauce. Toss everything together thoroughly, ensuring each piece of pasta is well-coated. If the sauce feels too thick, add in the reserved pasta water a little at a time until you achieve your desired consistency.
Step 8: Garnish and Serve
Remove the saucepan from heat and serve the creamy roast garlic and lemon pasta sauce immediately. For an extra burst of freshness, garnish each bowl with chopped fresh parsley. This delightful touch will enhance both the aroma and appearance, making your meal as pleasing to the eye as it is to the palate.

Creamy Roast Garlic and Lemon Pasta Sauce Recipe FAQs
How do I select the right garlic for roasting?
