This hearty spinach lemon pasta has become my weeknight dinner savior when time is short but I still want something fresh and vibrant. The combination of bright lemon, wilted spinach, and savory parmesan creates a perfectly balanced dish that comes together in just 20 minutes.
I first made this pasta during a particularly hectic week when I needed something quick yet satisfying. My family was skeptical about such a simple dish but after the first bite, it became an instant favorite that everyone requests regularly.
Ingredients
- 8 ounces spaghetti: the backbone of our dish, use good quality pasta for best texture
- 3 tablespoons unsalted butter: creates a silky base for our sauce, use European style for richer flavor
- 3 cloves garlic: brings aromatic depth, look for firm bulbs with tight skin
- ¼ teaspoon red pepper flakes: adds gentle heat without overwhelming, adjust to your preference
- 1 lemon: provides both zest and juice for brightness, choose heavy lemons with thin skin for more juice
- 2 cups baby spinach: adds color, nutrition and slight earthiness, select bright green crisp leaves
- ½ cup parmesan cheese: delivers savory richness, always grate fresh for best flavor and melting
- ½ teaspoon salt: enhances all flavors, plus extra for pasta water
- ¼ teaspoon black pepper: adds subtle warmth and depth
Step-by-Step Instructions
- Boil the Pasta:
- Bring a large pot of generously salted water to a rolling boil. Add spaghetti and cook according to package directions until al dente, usually 9 to 10 minutes. Before draining, scoop out and reserve 1 cup of the starchy pasta water. Drain pasta but never rinse it as the starch helps sauce adhere.
- Create the Flavor Base:
- In a large 12 inch skillet over medium heat, melt the butter completely until it starts to foam slightly. Add the minced garlic and red pepper flakes, stirring constantly to prevent burning. Cook just until fragrant, about 30 seconds to 1 minute. The aroma will intensify noticeably when ready.
- Build the Sauce:
- Pour in the freshly squeezed lemon juice and ½ cup of your reserved pasta water to the garlic butter mixture. Allow this liquid to come to a gentle bubble, which helps the flavors meld together. The acidity from the lemon will cut through the richness of the butter creating balance.
- Combine and Wilt:
- Add the drained pasta and fresh spinach to the bubbling sauce. Using tongs, continuously toss everything together until the spinach wilts down completely and the sauce coats each strand of pasta evenly. If the mixture looks dry, gradually add more pasta water, about ¼ cup at a time, until you achieve a silky consistency.
- Finish with Flavor:
- Remove the skillet from heat completely before adding the finishing touches. Sprinkle in the lemon zest, freshly grated parmesan cheese, salt, and black pepper. Toss gently but thoroughly to distribute all ingredients evenly. The residual heat will melt the cheese into a creamy coating without making it stringy.

The lemon zest is my secret weapon in this recipe. I always make sure to zest the lemon before juicing it, and I sometimes add a little extra at the end for an even brighter flavor. My daughter actually started eating spinach willingly after I introduced this pasta to our dinner rotation!
Perfect Pasta Water
The starchy pasta water is essential to creating the silky texture of this dish. I always make sure to salt my pasta water generously until it tastes like sea water. This not only seasons the pasta from within but also creates more flavorful pasta water for the sauce. Think of the pasta water as liquid gold that transforms a few simple ingredients into a restaurant quality sauce through its starchy magic.
Storage Tips
This spinach lemon pasta is best enjoyed immediately after preparation when the sauce is silky and the flavors are brightest. If you do have leftovers, store them in an airtight container in the refrigerator for up to 4 days. The pasta will absorb some of the sauce as it sits, so when reheating, add a splash of water or broth and a small pat of butter to refresh the consistency. Unlike many pasta dishes, this one does not freeze well due to the delicate nature of the sauce and spinach.
Serving Suggestions
This bright pasta makes a delightful meal on its own, but also pairs beautifully with complementary dishes. Serve alongside a simple green salad dressed with olive oil and lemon juice to echo the flavors in the pasta. For protein, grilled chicken, sautéed shrimp, or flaked salmon can be added directly to the pasta or served alongside. A glass of crisp Pinot Grigio or Sauvignon Blanc makes the perfect beverage pairing, highlighting the citrus notes in the dish.
Make It Your Own
This versatile recipe welcomes creative adaptations based on what you have on hand. Try swapping spinach for arugula or kale for different flavor profiles and textures. Fresh herbs like basil, parsley, or dill can be added at the end for additional brightness. For a protein boost without adding meat, toss in a can of drained white beans or chickpeas when adding the spinach. The pasta shape can also be changed based on preference, with shapes like orecchiette or farfalle working beautifully to catch the delicate sauce.
