First Step: Preheat your oven to 200 degrees Celsius, which is about 400 degrees Fahrenheit, to get that perfect caramelized garlic for your roast garlic pasta sauce. Remove the outer layers from the 2 whole heads of garlic and cut off the tops to expose the cloves, then drizzle them with 2 tablespoons of olive oil. Wrap the garlic in foil and roast for about 45 minutes until the cloves are soft and golden, filling your kitchen with a wonderful aroma that makes this creamy pasta sauce worth the wait.

Second Step: Once roasted, let the garlic cool for a few minutes so it’s easy to handle this prevents any burns and keeps things safe. Squeeze out the softened cloves and mash them into a paste using the back of a spoon, which adds that sweet, creamy base to your garlic lemon sauce and enhances its overall flavor.

Third Step: While the garlic roasts, cook your pasta 150g fresh per person or 100g dried in a pot of salted boiling water until it’s just a bit underdone. This slight undercooking allows the pasta to finish absorbing the flavors of the creamy roast garlic lemon pasta sauce, making every bite more delicious and tailored to different preferences, like using gluten-free options if needed.

Fourth Step: In a frying pan over medium heat, melt the 30 grams of cubed butter until it starts to brown lightly, which adds a deeper taste to your lemon pasta sauce. Add the ½ teaspoon of black pepper and stir it in, building a flavorful foundation that complements the roasted garlic paste you’ll mix next.

Fifth Step: Add the mashed roasted garlic paste to the pan and whisk it into the butter mixture, ensuring it’s fully incorporated for that signature creamy texture. Then, pour in the 1 cup of cream and keep the heat low to gently whisk it without boiling, adapting this step for low-calorie versions by using less cream if you’re watching your intake.

Sixth Step: Stir in the 2 to 3 tablespoons of freshly squeezed lemon juice and the zest of one lemon, which brightens the sauce and makes your garlic lemon sauce sing with zesty notes. Gradually add the 50 grams of finely grated parmesan cheese, whisking between each addition until it melts smoothly and thickens the sauce just right for coating your pasta perfectly.

Seventh Step: Toss the slightly undercooked pasta directly into the sauce along with about ¼ cup of reserved pasta water, then simmer briefly until everything bubbles and coats evenly. If the sauce seems too thick, add a bit more pasta water to adjust, and consider variations like adding veggies for diet-conscious folks to make this creamy roast garlic lemon pasta sauce even more versatile.

Final Step: Serve your dish right away, topped with extra lemon zest and optional dried paprika flakes for a fresh finish. This creamy pasta sauce pairs great with simple sides, and for more ideas, check out our creamy chicken and bacon pasta recipe for complementary dishes.
