Spinach pesto pasta is one of those wonderfully simple dinner recipes that proves you don’t need a long ingredient list to make something seriously delicious. Ready in just 25 minutes, this vibrant pasta combines tender baby spinach, fragrant fresh basil, sharp Parmigiano Reggiano, garlic, lemon and extra virgin olive oil for a bright, herby sauce that clings beautifully to every bite.
I love this kind of easy pasta recipe for busy weeknights because it feels fresh and homemade without turning dinner into a major kitchen project. The spinach brings a nutritious twist to traditional pesto, while basil keeps that familiar Italian-inspired flavor we all know and love.
Pesto itself is strongly associated with Genoa and the Ligurian region of Italy, where classic pesto alla Genovese is traditionally made with basil, pine nuts, garlic, cheese and olive oil. This version takes inspiration from that beloved combination but swaps in a generous amount of baby spinach. The result is a gorgeous green pasta sauce that’s lighter, fresh-tasting and incredibly easy to prepare.
Whether you’re looking for a quick vegetarian pasta dinner, healthy pasta recipes for the family, or simply a clever way to use a bag of spinach, this recipe deserves a spot in your weeknight rotation.
Why You’ll Love This Spinach Pesto Pasta
There is so much to love about this quick pasta dinner.
First, the entire recipe takes only 25 minutes from start to finish. While your pasta cooks, you can blitz the pesto ingredients together, meaning there’s very little waiting around.
Second, the ingredient list is wonderfully uncomplicated. You need pasta, spinach, basil, Parmesan-style cheese, lemon, garlic, olive oil and chilli flakes. That’s it.
And third, the flavor is anything but boring.
The spinach gives the pesto its vibrant green color and a mild earthy flavor, while fresh basil adds that unmistakable aromatic note. Garlic gives the sauce savory depth, Parmigiano Reggiano brings salty richness, and lemon zest and juice add just enough brightness to stop everything from feeling heavy.
Then there’s the chilli. A sprinkling of dried chilli flakes at the end gives every forkful a gentle kick.
It’s exactly the sort of easy dinner recipe I want on a hectic evening: colorful, comforting, satisfying and fuss-free.
Spinach Pesto Pasta Ingredients
For four generous servings, you’ll need:
- 360g ditaloni rigati or another short tube pasta
- 260g baby leaf spinach
- ½ x 25g pack fresh basil, leaves only
- 50g Parmigiano Reggiano, grated, plus extra for serving
- Zest of ½ lemon
- 1 teaspoon lemon juice
- 2 garlic cloves, crushed
- 80ml extra virgin olive oil
- 1–2 teaspoons dried chilli flakes, for serving
The choice of pasta is worth mentioning. Ditaloni rigati is particularly good because those little ridges and tubes give the pesto plenty of places to hide. Every spoonful ends up coated with that gorgeous green sauce.
Don’t have ditaloni? No problem. This recipe works beautifully with penne, rigatoni, fusilli or another short pasta shape. For pesto pasta recipes, shapes with ridges, grooves or twists are especially useful because they grab onto the sauce.
How To Make Spinach Pesto Pasta
Start by bringing a large saucepan of generously salted water to a boil. Cook the pasta according to the packet instructions until al dente.
While the pasta is cooking, prepare the spinach pesto.
Add the baby spinach, fresh basil leaves, grated Parmigiano Reggiano, lemon zest, lemon juice and crushed garlic to a food processor. Begin blending while gradually adding the extra virgin olive oil.
Blend until the ingredients form a vibrant green pesto. You can make it completely smooth or leave a little texture, depending on your preference.
Taste the pesto and adjust if needed. The Parmesan should provide plenty of savory saltiness, while the lemon should add a fresh little lift.
Once the pasta is cooked, drain it, reserving a little of the pasta cooking water before draining.
Return the pasta to the saucepan and add the spinach pesto. Toss everything together until the pasta is beautifully coated.
If the sauce seems a little thick, add a small splash of reserved pasta water and toss again. The starchy water helps loosen the pesto and encourages it to coat the pasta rather than sitting in one thick layer.
Finish with extra grated Parmigiano Reggiano and a generous sprinkling of dried chilli flakes.
And that’s dinner done!
What Does Spinach Pesto Taste Like?
If you’ve never tried spinach pesto before, expect something fresh, savory and pleasantly herby rather than overwhelmingly “green.”
Baby spinach has a much milder flavor than many people expect, so it doesn’t overpower the basil. Instead, it gives the pesto body, color and a subtle earthy note.
The basil adds aromatic freshness, while garlic provides the savory backbone. Parmigiano Reggiano gives the sauce a delicious salty richness, and lemon zest and juice bring everything into balance.
I particularly love the combination of lemon and chilli here. The lemon keeps the pesto tasting bright and fresh, while the chilli flakes add a little warmth at the finish.
It’s a lovely alternative to heavier pasta sauces when you’re craving something satisfying but don’t want a creamy or tomato-based dish.
My Best Tips For Perfect Spinach Pesto Pasta
1. Don’t overcook the pasta.
Aim for al dente pasta so it retains a little bite. It also holds up better when tossed with the pesto.
2. Use baby spinach.
Baby leaf spinach has a delicate flavor and blends easily into the pesto. It also gives you that beautiful vibrant green color.
3. Don’t skip the lemon.
It might look like a small ingredient, but lemon zest and juice make a huge difference. The acidity cuts through the richness of the olive oil and cheese and makes the pesto taste brighter.
4. Save some pasta water.
This is one of my favorite pasta-making tricks. A splash of starchy cooking water can transform a thick pesto into a silky sauce that coats the pasta evenly.
5. Add the chilli at the end.
Sprinkling dried chilli flakes over the finished dish lets you control the heat. Start with one teaspoon and add more if you like your pasta with a little extra fire.
Easy Ways To Customize This Recipe
One of the best things about spinach pesto pasta is how adaptable it is.
For extra protein, add grilled chicken, cooked prawns or crispy chickpeas. You could also fold through white beans for a simple vegetarian option.
Want more vegetables? Try adding roasted cherry tomatoes, peas, asparagus or lightly sautéed courgette.
For an even richer finish, add a little extra Parmigiano Reggiano just before serving.
You can also experiment with the pasta shape. Penne makes this a brilliant family-friendly dinner, while fusilli creates lots of little grooves for catching the pesto.
And if you’re planning easy meal prep recipes, this pasta can be portioned into containers for a convenient lunch. Store it chilled and add a tiny splash of water or olive oil when reheating to help loosen the sauce.
What To Serve With Spinach Pesto Pasta
This pasta is filling enough to serve as a complete main meal, but a few simple sides can turn it into a lovely Italian-inspired dinner.
A crisp green salad with lemon dressing would complement the bright pesto beautifully. You could also serve it with roasted vegetables or warm crusty bread for scooping up any pesto left on the plate.
For a dinner party, serve smaller portions alongside grilled chicken, roasted vegetables or a simple tomato salad.
The fresh green color also makes this an especially pretty dish for spring and summer entertaining.
Frequently Asked Questions
Can I use frozen spinach?
Fresh baby spinach is ideal for this recipe because it blends easily and provides a fresh flavor. Frozen spinach can work in a pinch, but it should be thoroughly thawed and squeezed dry first because excess water can make the pesto too loose.
Can I make spinach pesto ahead of time?
Yes. The pesto can be prepared ahead and kept chilled until you’re ready to cook the pasta. Give it a good stir before using.
What pasta works best with spinach pesto?
Short pasta shapes such as ditaloni, penne, rigatoni and fusilli are excellent choices because their ridges and curves hold onto the pesto.
Is spinach pesto pasta vegetarian?
The ingredients in this version are vegetarian-friendly if the cheese you use is suitable for your dietary requirements. Always check the label of your Parmigiano Reggiano and other ingredients if you’re cooking for a specific dietary need.
How can I make the pasta less spicy?
Simply reduce or omit the dried chilli flakes. The pesto itself has plenty of flavor without them.
