Lemon tahini pasta with spinach is a simple stovetop dish where hot pasta gets tossed with a sauce made from tahini, lemon juice, garlic, and a splash of pasta water. The sauce turns silky and coats the noodles without any cream or cheese in the mix.
I make this on nights when I want something warm but don’t want to stand over the stove for long. The tahini brings a nutty, slightly bitter edge, and the lemon cuts through it so the sauce stays bright instead of heavy.
Baby spinach wilts right into the hot pasta in the last minute, so there’s no extra pan to wash. If your tahini seizes up and turns clumpy when you add the lemon juice, don’t worry, a splash of warm pasta water loosens it right back to smooth.
This one is done from start to finish in about 25 minutes, and it holds up fine as leftovers for lunch the next day.
Why You’ll Love This Recipe
- Ready in 25 minutes with basic pantry ingredients
- One pot for both the pasta and spinach
- Tahini sauce needs no cream or cheese
- Leftovers taste good cold or reheated
Ingredient Notes
- tahini: Use a well-stirred, runny tahini. If yours is thick and dry, whisk in a bit more olive oil before adding the lemon juice.
- lemon juice: Fresh lemon juice and zest give the sauce a sharper, brighter flavor than bottled juice.
- pasta: Casarecce, fusilli, or spaghetti all work here. Pick a shape that holds sauce in its ridges or curves.
- baby spinach: Baby spinach wilts fast and doesn’t need chopping. Regular spinach works too, just tear the leaves first.
- garlic: Fresh minced garlic gives the sauce a sharper bite than the jarred kind.
Easy Creamy Lemon Tahini Pasta with Spinach and Garlic
Ingredients
Method
- Bring water to a boil in a 4-quart / 4L pot. Salt it generously, then add the pasta.
- Cook the pasta according to package directions until al dente, about 9 to 11 minutes. Scoop out 1 cup (240 ml) of the starchy cooking water before draining, then drain the pasta in a colander.
- While the pasta cooks, whisk the tahini, lemon juice, lemon zest, minced garlic, olive oil, salt, and black pepper together in a large mixing bowl. The mixture will look thick and grainy at first, that's normal.
- Add 3 tbsp of the hot reserved pasta water to the tahini mixture and whisk again until it turns smooth and pourable. Add another tablespoon of warm water if it still looks clumpy.
- Add the drained hot pasta directly to the bowl with the sauce. Toss well with tongs so every strand gets coated.
- Add the baby spinach and toss again. The heat from the pasta wilts it within a minute or two.
- Loosen the pasta with more reserved pasta water, a tablespoon at a time, until the sauce clings to the noodles but still moves when you shake the pot.
- Taste and adjust with more salt, lemon juice, or red pepper flakes if using.
- Divide among bowls and serve right away.
Notes
- Reserve pasta water before draining, you'll need it for the sauce.
- Whisk tahini and lemon together first to avoid a grainy sauce.
- Add spinach off the heat so it wilts without turning mushy.
- Taste before adding extra salt since tahini is already salty.
Tips for Success
- Reserve at least 1 cup of pasta water before draining, you’ll need it to loosen the sauce.
- Whisk the tahini and lemon juice together before adding hot water, or the sauce may separate.
- Add the pasta water gradually, a tablespoon at a time, until the sauce clings but still moves.
- Taste the sauce before adding extra salt, since tahini already carries some natural saltiness.
- Toss the spinach in while the pasta is still hot so it wilts without any extra cooking step.
Variations
- Add a can of drained chickpeas for extra protein and a heartier bite.
- Stir in a spoonful of harissa or extra red pepper flakes for a spicier version.
- Top with toasted pine nuts or sesame seeds for a bit of crunch on top.
Storage and Reheating
Lemon tahini pasta keeps in an airtight container in the fridge for 3 to 4 days. The tahini sauce firms up as it chills, so don’t be surprised if it looks thick when you pull it out.
To reheat, warm it in a skillet over low heat with a splash of water or lemon juice, stirring until the sauce loosens back up, about 3 to 4 minutes. You can also microwave it in 30-second bursts, stirring in a little water each time.
I don’t recommend freezing this one. The spinach turns watery and the tahini sauce can break when thawed.
Serving Suggestions
I like this pasta on its own for a quick lunch, but a side of crusty bread is good for scraping up the last of the sauce. Roasted chickpeas or a simple cucumber and tomato salad make it a fuller meal.
For dinner, add it alongside grilled chicken or salmon if you want more protein on the plate. A sprinkle of red pepper flakes or extra lemon zest on top wakes up the flavor if the pasta has been sitting a bit.
FAQ
Why did my tahini sauce turn clumpy and grainy?
This happens when lemon juice hits the tahini before there’s enough liquid to smooth it out. Add the hot reserved pasta water a tablespoon at a time, whisking after each addition, until the sauce turns pourable again. It usually takes 2 to 3 tablespoons total.
Can I use peanut butter instead of tahini in this pasta?
Yes, but the flavor changes since peanut butter is sweeter and less bitter than tahini. Use a natural, unsweetened peanut butter and add a bit more lemon juice to balance the sweetness. The sauce will taste noticeably different but still work with the pasta and spinach.
Can I make lemon tahini pasta ahead of time for meal prep?
Yes, you can cook the pasta and make the sauce a day ahead and store them separately in the fridge. Toss them together with a splash of warm water when you’re ready to eat, since the sauce thickens as it sits. Add the spinach fresh at that point so it doesn’t turn soggy.
What can I add to lemon tahini pasta to make it a full meal?
Chickpeas, roasted vegetables, or grilled chicken all work well stirred into the finished pasta. A handful of toasted pine nuts or sesame seeds on top adds texture without much extra work. I also like a side salad with cucumber and tomato for something fresh.
Is lemon tahini pasta vegan and dairy-free?
Yes, this recipe has no dairy or animal products in the sauce, pasta, or spinach. Use standard wheat pasta as written, or swap in a gluten-free pasta if you need that too. Double check your pasta brand’s label if you’re strict about cross-contamination.
Is lemon tahini pasta a traditional Mediterranean recipe?
No, it’s not a traditional dish. Tahini and lemon are staples in Middle Eastern cooking, often used in hummus or dressings, but pairing them with pasta is more of a modern combination that borrows those flavors rather than a classic recipe.
