Why I love this lemon and spinach pasta

  • This quick and easy lemon spinach pasta is one of my favourite lemon pasta recipes. The speedy secret of this pasta is that it uses a no-cook sauce. Even the spinach requires no cooking. Simply combine the sauce ingredients and the spinach with hot pasta, toss and enjoy.
  • And this pasta has another secret to making it delicious. Adding a whole lemon to the pasta water while it comes to a boil, infuses some lemon flavour right into the pasta. When the whole lemon is removed before adding the pasta, let it cool, then juice it for the sauce. You’ll be amazed at how much juice comes out of it!

Ingredients and substitutions

Ingredients to make lemon spinach pasta.

A few notes about the key ingredients …

Crème Fraîche – Crème Fraîche is recommended, if you have it on hand. I regularly make my own Crème Fraîche. It keeps a long time in the fridge! If you don’t, here are some substitution ideas …

You could also substitute mascarpone if you have that on hand. Finally, a decent substitute would be heavy whipping cream mixed with a bit of full-fat sour cream.

How to make Crème Fraîche: Simply combine 1 cup heavy, whipping cream with 2 Tbsp buttermilk in a jar. Cover loosely and let stand on your counter for 8-24 hours, until thickened. You could do this in the morning and have it ready to enjoy by dinner time!

Spinach – As for the spinach, go with baby spinach or small, fresh spinach leaves roughly chopped, to ensure it wilts well with just the heat of the pasta. Have arugula? Go ahead and use that instead of the spinach.

Pasta – I love this sauce with a long pasta such as spaghetti, linguini or angelhair pasta. That said, any pasta will work just fine.

Recipe tips!

  • I prefer not to drain my pasta. I have always hated carrying a heavy pot of boiling water across the kitchen! That said, if you prefer to drain, do remember to save some of the pasta water before draining and then, rather than having another pot to wash, return the pasta to the now empty pot you used to boil the pasta and add the sauce, spinach and lemon juice to the hot pasta and toss.

How to serve lemon spinach pasta

Lemon spinach pasta is lovely served with a side salad or a steamed green vegetable, such as green beans, broccoli or broccolini.

5 stars from 6 ratings
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Yield: 2 servings

Ingredients

  • 1 whole lemon, scrubbed to clean
  • 6 oz spaghetti, linguini or similar long pasta, about 2 servings

Sauce:

  • 1/3 cup Crème Fraîche, *see Note 1 below for substitutions
  • 1/2 cup Parmesan cheese, freshly grated, plus more for garnish
  • Zest from 1/2 of the whole lemon
  • Salt and freshly ground pepper

To serve:

  • 2 cups baby spinach, or larger spinach, chopped
  • Juice from the 1 whole lemon above
  • Salt and freshly ground pepper
  • Red pepper flakes

Instructions
 

  • Tip! The base recipe is for 2 servings. Double or triple the recipe as needed to feed more (use the 2X or 3X buttons at the top of the recipe card to adjust the ingredients). Be sure not to cook too much pasta or you'll find there isn't enough sauce.
  • Scrub the whole lemon, then remove the zest from about 1/2 of the whole lemon and set the zest aside for the sauce. Add the whole lemon to a large pot of water and bring the water with the lemon to a boil over high heat. Once the water boils remove the lemon and set it aside to cool. Add salt to the boiling water, then add the pasta. Cook the pasta to al dente according to the package directions.
  • Tip! I prefer not to drain my pasta as I hate carrying a heavy pot of hot water across my kitchen. If you prefer to drain your pasta, be sure to reserve some of the pasta-cooking water before draining. Then, instead of dirtying another pot, return the drained pasta to the same pot and add the sauce and spinach to the pasta and toss.
  • Meanwhile, stir together the crème fraîche, Parmesan cheese, lemon zest, salt and pepper in a small bowl. Add the sauce mixture to a cold skillet on the stovetop. Prepare your spinach and add it to the skillet as well. Let stand until the pasta is cooked.
  • When the boiled lemon is cool enough to handle, cut it in half and juice the lemon. Pour the lemon juice through a strainer into a small bowl, to remove seeds and pulp. Set aside. 
  • When the pasta is cooked, use tongs to remove the cooked pasta to the skillet with the sauce and spinach. Turn the heat on under the skillet to medium heat. Add a few Tablespoons of the pasta-cooking water to the skillet and use tongs to toss the pasta with the sauce and spinach until the spinach begins to wilt. Drizzle the pasta with the lemon juice and toss to combine. Cook the pasta in the skillet briefly, adding a bit more pasta-cooking water to the skillet if the pasta seems dry. Season with salt and freshly ground pepper, to taste. Serve with additional freshly grated Parmesan, some red pepper flakes, if using and more freshly ground pepper.

Notes

Note 1: If you don’t have crème fraîche on hand, you could substitute mascarpone or try heavy cream with a bit of full-fat sour cream mixed in. I like to make my own crème fraiche. It keeps well in the fridge for quite some time!
How to make Crème Fraîche: Simply combine 1 cup heavy, whipping cream with 2 Tbsp buttermilk in a jar. Cover loosely and let stand on your counter for 8-24 hours, until thickened. You could do this in the morning and have it ready to enjoy by dinner time!
