Ingredients
Method
- Bring a large pot of generously salted water to a boil. Add the spaghetti and cook until al dente according to package instructions (usually 8–10 minutes).
- Before draining, reserve ½ cup of pasta water — this starchy liquid will help thicken the sauce later. Drain the pasta, toss it with a drizzle of olive oil to prevent sticking, and set aside.
- Heat a large skillet over medium-low heat. Add the butter and 4 tablespoons olive oil. Once the butter melts, add the minced garlic and sauté for 1–2 minutes, stirring constantly to prevent burning.
- Stir in the Italian seasoning and lemon zest, toasting them with the garlic for 30 seconds to release their oils.
- Pour the lemon juice into the skillet and let the mixture simmer for 1–2 minutes, allowing the acidity to mellow and blend with the butter and olive oil.
- Add the cooked spaghetti to the skillet, tossing thoroughly to coat the pasta in the sauce. Gradually pour in the reserved pasta water, 2–3 tablespoons at a time, while stirring continuously.
- Remove the skillet from heat. Fold in the chopped parsley and season generously with kosher salt and fresh cracked pepper. Taste and adjust the lemon zest, salt, or pepper as needed.
- Divide the pasta among bowls. Top with a sprinkle of grated Parmesan cheese and a pinch of crushed red pepper flakes for a subtle kick. Serve immediately while hot.
Notes
If you’re making lemon garlic pasta, a few simple tricks can take it from good to unforgettable. First, skip the bottled lemon juice — freshly squeezed lemon juice and zest are non-negotiable if you want that bright, clean citrus flavor.
When cooking the garlic, keep the heat low; burnt garlic turns bitter fast, so if it starts to brown too quickly, just pull the skillet off the heat for a moment. The secret to a silky, cohesive sauce? Emulsify it by slowly adding pasta water — this helps the butter, lemon, and garlic cling beautifully to every noodle instead of separating into an oily mess.
