This Leek Pasta is fresh and ready in only 30 minutes!

Pasta is one of my all-time favorite things to cook. I love that you can combine it with any combination of ingredients and in 30 minutes you have a tasty and satisfying meal.
I went gluten free a year ago (do you you get a reward or a trophy or something for your 1 year gluten-freeiversary)? Is that a thing?
One food that I wasn't about to give up with along with gluten is pasta. There are lots of gluten free pasta products on the market today and I was introduced to one earlier this year that I come back to over and over again.
That pasta is the Red Lentil Penne and Red Lentil Rotini from Barilla. I love the texture AND taste of this pasta. I've created a number of recipes using this stuff and enjoyed every single one of them. Part of the reason for that is the 'al dente' texture - It holds up perfectly to anything you add to it.
This time I wanted to pair it with an ingredient that tends to get overlooked for no good reason - Leeks. Leeks are a hearty member of the onion family and provide great savory flavor.

There are many reasons to love this Barilla Red Lentil Penne and among them is the fact that it is made with only ONE ingredient - Lentils. If you're gluten free you're used to reading labels, trying to decipher the mysterious ingredients on the package. You don't have to do that with this pasta - There's nothing hiding in here.
Lentils are a great source of plant-based protein and high in fiber. This Red Lentil Pasta is vegetarian and vegan so it's suitable for all kinds of diets.
You can grab a multi-pack (it includes both the Red Lentil Penne and Rotini) on Amazon. This allows you to try both varieties and the 4-pack lets you stock up a bit. I don't know about you guys but I always love to have a few boxes of pasta on hand!
Barilla makes a Chickpea version as well and it's made with only one ingredient as well. That's right - Chickpeas.

How To Cut Leeks
Leeks have a flavor that is a bit more mild than onions. It's somewhere between an onion, shallot, garlic, and a scallion. The flavor is a bit nutty and leeks are often used in soups, stews, roasted meats, and paired with chicken.
You can find them in the produce section of the grocery store.
Leeks are not difficult to cut but it's important to remove any dirt that might be hiding in there.
- To cut the leeks remove the dark green woody tops and the hairy portion at the bottom with a knife. The light green and white portion are the edible parts of the leek.
- Cut 2 leeks into thin slices. Place the leek slices into a bowl of cold water. This will get rid of any dirt.
- Scoop the leek slices out and place them in a strainer or colander using a slotted spoon or spider strainer.
- Place the leek slices on a towel or paper towel and pat dry.

How To Make Lemon Leek Pasta
Two large leeks should yield 2-3 cups of sliced leeks.
You can't make a pasta recipe without adding some garlic (I think this is some kind of universal rule or law).
- Mince 4 cloves of garlic.
- Heat a skillet to medium and add 2 Tbsp. of extra virgin olive oil. Once the oil is heated add the garlic and leeks along with a ¼ tsp. kosher salt and pepper. Saute on medium-low for 8-10 minutes, stirring occasionally.
The leeks will cook down a bit and start to caramelize. The leeks along with the garlic are super fragrant and smell amazing as they cook!
Boil a pot of water and prepare one package of Barilla Red Lentil Rotini pasta according to package instructions. Feel free to boil the pasta as the leeks are cooking.

What Flavors Go Well With Leeks?
Once the pasta is finished cooking drain and reserve 1 cup of the pasta water.
I thought this pasta needed a hearty green so I went with kale.
Can I Substitute Any Other Greens?
Yes! You can use any type of hearty green that you like with this recipe - Spinach, Swiss chard, arugula. If kale isn't your thing there are lots of other options!
- Chop 2 cups of kale or leafy green.
- Add the cooked pasta to the skillet along with the reserved cup of pasta water, the chopped kale, and another ¼ tsp. of kosher salt and pepper.
- Cook for another 4-5 minutes or until the kale wilts down a bit.

Garnish The Leek Pasta
Leeks are often paired with heavy ingredients like cream, bacon, or pancetta but I wanted to keep things light and stick with Mediterranean flavors. There's no cream but to bump up the 'gourmet factor' I thought it best to add some lemon and Parmesan cheese.
- Zest 2 lemons into the pasta using a microplane or small grater and then add the juice of the lemons.
- Add 1 cup of shaved or shredded Parmesan cheese to the pasta.
- Stir in the lemon zest, juice, and Parmesan cheese allowing it to melt slightly.

What To Serve With Lemon Leek Pasta
I love the brightness that the lemon juice and zest gives this pasta. Leeks are kale are earthy in flavor as are lentils and the lemon makes it pop.
To garnish I added some chopped walnuts for texture, minced basil, and some extra shaved Parmesan cheese.
You can use any type of nut to garnish - Almonds, pine nuts, or hazelnuts would be delicious!
Feel free to use any type of fresh herbs you like to garnish - Parsley, chives, or even mint are great options.
You could even add some capers, artichokes, or olives for an extra salty kick.
Healthy pasta recipes like this one are great served with Sheet Pan Italian Chicken, Grilled Bruschetta Chicken, or Lemon Tarragon Chicken Salad.
It would pair nicely with a bright salad like this Marinated Tomato Salad and Minty Pea and Almond Salad.
If you love Mediterranean flavors this Kalamata Olive Tapenade, Roasted Mushroom Tapenade, or Asparagus with Prosciutto are great options!

How Long Does This Pasta Last In The Fridge?
This pasta lasts 2-3 days stored in an airtight container in the fridge. Make sure to allow the pasta to cool completely before transferring to the fridge if storing.

I made this for dinner and it was such a great hit! I used spinach as that is what I had on hand and it was just delicious. Thank you for the recipe
Jenni
This pasta was so good! I have been looking for a way to use the new red lentil pasta I kept seeing in the store, and this recipe was the right fit! It was so simple and so delicious!
Jamie
I love the flavor of lemon in this pasta. It pairs perfectly with the leeks and lentil pasta!

First of all, yes, you deserve a trophy. Something with a big x through a stalk of wheat, or something. It'd look nice on the mantle.
Secondly, I'm totally with you - nothing beats a simple but amazing pasta meal. There are endless options! I love lemons with pasta, and I really like how you've incorporated them here with leeks and walnuts. I haven't actually tried the lentil pasta yet, but it looks really good, so I think I'll have to give it a try. Cheers!
