Ingredients
For the Flavor Base
- 1 tbsp olive oil
- 2 cloves garlic minced
- Pinch of red pepper flakes
For the Pasta and Sauce
- 2 cups vegetable or chicken broth (or water
- 8 ounces dried short pasta (penne, fusilli, or farfalle)
- 1 tbsp lemon zest
- 2 tbsp fresh lemon juice
- 1/2 cup finely grated Parmesan cheese
- Salt and freshly ground black pepper
Instructions
Step 1: Build the Flavor Base
- Before you start cooking, mince the garlic, zest and juice the lemon, and measure out your Parmesan — everything moves quickly in a one-pot dish, so having it all within reach makes the process seamless. Heat the olive oil in a wide, deep skillet or saucepan over medium heat. Add the garlic and red pepper flakes, if using, and cook for about 30–60 seconds, stirring constantly, until fragrant and just golden. Don't let it brown.
Step 2: Cook the Pasta in One Pot
- Pour in the broth or water and increase the heat to bring it to a gentle boil. Add the pasta and stir well to prevent sticking. Cook, stirring occasionally, according to the package directions for al dente — but aim to pull back about 1–2 minutes early. You want the pasta slightly underdone at this stage, as it will finish in the sauce. Reserve a small cup of the starchy cooking liquid before the pasta fully absorbs it.
Step 3: Create the Lemon Parmesan Sauce
- Reduce the heat to low. Stir in the lemon zest, then gradually add the grated Parmesan in small handfuls, stirring continuously so it melts into a smooth, creamy sauce rather than clumping. Add a splash of the reserved cooking liquid as needed to loosen the sauce and help it emulsify into a silky coating around every piece of pasta. Stir in the lemon juice and taste — adjust with more lemon, salt, or black pepper to your liking.
Step 4: Finish and Serve
- Remove the pan from the heat and fold in a final squeeze of lemon juice for brightness. The residual heat will continue to thicken the sauce slightly, so serve right away. Divide between warm bowls, scatter over fresh parsley, and finish with a generous handful of extra Parmesan and an optional drizzle of good olive oil. Best enjoyed immediately while the sauce is at its creamiest.
