Bring a large pot of salted water to a boil and cook the pasta according to package instructions. Make sure it’s al dente, as it will cook slightly more later. Reserve about half a cup of pasta water before draining. This starchy water helps create a silky sauce.
In a bowl, combine ricotta cheese, lemon zest, lemon juice, olive oil, and grated parmesan. Mix until smooth and creamy with a slightly thick consistency. Season with salt and pepper to taste. This mixture forms the base of your flavorful sauce.
Heat a bit of olive oil in a large skillet over medium heat and add minced garlic. Cook for about 1 minute until fragrant but not browned. Be careful not to burn it, as it can turn bitter. This step adds depth to the overall flavor.
Add the drained pasta directly into the skillet with garlic. Remove from heat and quickly stir in the ricotta mixture. Toss everything together until evenly coated. Add reserved pasta water gradually to loosen the sauce and make it creamy.
Fold in the fresh arugula while the pasta is still warm. It will wilt slightly, adding a fresh, peppery taste. Mix gently so the greens stay vibrant and don’t overcook. This step balances the richness of the dish beautifully.
Taste and adjust seasoning if needed with more salt, pepper, or lemon juice. Sprinkle extra parmesan on top before serving. You can also drizzle a little olive oil for added richness. Serve immediately for the best texture and flavor.
