🛒 Ingredients and variations:

This zesty spinach sauce just requires 5 simple ingredients: fresh spinach, lemon, Parmesan, garlic powder and creme fraiche.

  • Spinach: use fresh spinach or baby spinach instead of frozen. This recipe has not been tested with frozen spinach and it is likely to increase the water content in the sauce.
  • Crème fraîche: the recipe has been tested with light crème fraîche. You could also use full fat crème fraîche, but this is likely to make the sauce a little thicker. Add a very small amount if this is the case. Avoid using heavy cream or cream cheese because you won't get the right consistency and the sauce would also be too rich. Sour cream is the best alternative if you don't have crème fraiche.
  • Garlic powder: you can also use a clove of fresh garlic, but you will need to mellow it first, so it doesn't add an unwanted sharp flavour to the sauce.
  • Parmesan: you can also use freshly grated pecorino or Grana Padano.
  • Olive oil: you can use butter instead to toast the breadcrumbs

🧑‍🍳 Spinach Pasta Sauce in 3 easy steps

1. Blend

Place the spinach and the rest of the ingredients for the sauce into your food processor and blitz until you get a pureed sauce, scraping off any chunks that are stuck to the sides as you go.

2. Parmesan crumbs

Place a skillet over a medium heat and add olive oil (or melted butter). Add the breadcrumbs when the oil is hot and stir in a little bit of lemon zest and garlic powder. Remove them from the pan when they begin to brown, place them into a bowl and stir in the Parmesan.

3. Serve with pasta or ravioli

Add the spinach sauce to freshly cooked pasta or ravioli, top with Parmesan crumbs and enjoy.

🍝 Serving suggestions


Just cook your favourite pasta shape according to the package directions in a large pot of boiling water, drain, stir in the spinach pasta sauce, and serve immediately topped with the parmesan and lemon crumbs.

If you're wondering which pasta shape would be best suited for this sauce rest assured that it will taste great with most long and short pasta shapes. Fusilli and Riccioli tend to be my go-to's. Penne, farfalle, rigatoni, linguine and tagliatelle are also strong options.


This spinach sauce is sure to take a packet of store-bought ravioli to the next level and is an excellent alternative to tomato sauce or creamy sauce. Just combine it with cooked ravioli and serve. Any type of cheese-filled ravioli will pair up nicely such as spinach ricotta, tomato and mozzarella or mushroom.

Add chicken:

If you feel that your spinach pasta requires some additional protein, add some bite-sized chunks of chicken into the mix. Simply sauté some pieces chicken breasts or boneless chicken thighs in a skillet or take the opportunity to use up leftover cooked chicken.

Top tip: Reserved pasta water adds silky richness and additional flavour to any pasta dish. Set a cup of pasta water aside before you drain the cooked pasta and stir it into the spinach sauce before you add it to the pasta.

👍 Top tips for perfect Spinach pasta sauce

  1. Scrape the sides of the food processor - you'll probably find stray pieces of spinach get stuck to the sides. I always do! Scrape these back into the sauce with a spatula to ensure your spinach sauce is perfectly smooth.
  2. Use garlic powder instead of fresh - fresh garlic will work as well, but it will add a sharp bitter taste if you don't mellow it first. It's much easier to use garlic powder.
  3. Don't turn your back on the Parmesan and lemon crumbs - they can go from nicely brown to burnt in a matter of seconds.

🙋 FAQs

Is spinach pasta healthy?Spinach pasta is much more nutritious than traditional cream and meat sauces. Spinach contains antioxidants, iron, magnesium, vitamin A and vitamin K.

How can I use a lot of spinach?There are lots of options and therefore no excuse to let spinach go to waste. You can make pesto, or another type of spinach pasta sauce, a spinach dip, spinach soup, Spanakopita or saag paneer.

📦 Storage

Blended spinach pasta sauce can be stored in the refrigerator for up to 3 days. Just make sure you cover it with cling film / plastic wrap or put it into an airtight container.

It is safe to freeze the sauce for up to 3 months, although I wouldn't recommend it. Freezing is likely to alter the consistency of the sauce because crème fraiche is sensitive to frozen temperatures. Plus, the sauce is so easy and quick to prepare, that there's no reason not to whip up a fresh batch each time.

      Hi, I just checked myself and it didn't work for me the first time I tried, but then it was fine the second time - seems buggy. I might look into investing in another social sharing solution. Here's a link to the pin from one of my boards. Hope you enjoy the recipe, let me know what you think, I love feedback!

    Is this sauce also a good fit for a risotto which I am going to try for the first time. In the meantime I will give this recipe try as it sounds delicious.

    • Helen | Knife & Soul Helen | Knife & Soul on Mar 24, 2022

      I haven't tried it with risotto, but I don't see why not. The sauce is a similar consistency to pesto, would recommend making the risotto first and then stirring the sauce in at the end.
