Creamy Leek Pasta

A creamy pasta dish is total comfort food and this one couldn't be easier. Just 5 ingredients go into making this creamy leek sauce, which goes perfect on top of pasta, or even mashed potatoes. Creamy Leek Pasta is a great way to make use of the, in my opinion, underused leek, and something a little bit different for pasta night.

I love leeks, and I always forget how much I love them. I don't think they get enough love in the recipe website world, and we are trying to change them. Using them in a pasta sauce is such a simple way to include them more in your diet.

Ingredients and Substitutions

A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.

• Pasta - Any pasta will work here, but we used spaghetti as the creamy sauce really clings to it.
• Leeks - Such an underrated vegetable in my opinion. You can buy them ready sliced to save some time, as they can be a little tricky to clean.
• Garlic - Use frozen crushed garlic to save time.
• Mustard - A little Dijon mustard adds a delicious flavour to this leek pasta. You could use wholegrain instead.
• Cheese - We used a vintage cheddar, as it has such a strong flavour so a little goes a long way. You could use mozzarella to make it extra cheesy.
• Creme fraiche - This is where the creamy sauce comes from. Use reduced fat to lower the calories.

Variations

We love a recipe that you can adapt, and this one is exactly that. You could add some chopped mushrooms (a mixture of types) to the leeks for extra flavour and texture. You could even add some small diced chicken breast, but note that cooking times would vary.

We added a sprinkling of parsley at the end, however fresh chives or dill would work too. You could even add a sprinkle of red chilli flakes for some heat.

How to Prepare Leeks

It's really easy to prepare and cut up a leek, so don't be put off doing it. Simply chop off the root end, and most of the green stem (these can be kept to make stock with).

Cut the leek in half lengthways, and then each in half again until you have 4 long quarters. Slice them all up and then rinse them in water to make sure you have all the dirt off. Drain them and pat dry to get the excess water off.

Step by Step

1. Step 1: Put the pasta in a pan of boiling water and cook for 12 minutes.

2. Step 2: Put some oil it a pan and add the leeks. Gently cook on a very low heat for 5-7 minutes, until softened.

3. Step 3: Add the garlic, mustard, creme friache and cheese to the pan.

4. Step 4: Stir well and cook on a very low heat for a further minute.

5. Step 5: Drain the pasta and stir into the sauce.

Creamy Leek Sauce

I mean, the recipe is really all about the sauce. And what a sauce it is! Low and slow cooked leeks mixed with plenty of garlic, mustard, creme friache and cheddar. It's creamy, has a bit of a punch from the mustard and plenty of kick from the garlic. It really is everything you could want from a creamy sauce.

We have used reduced fat creme fraiche, however you could use full fat, or even cream if you wanted to. We also used a reduce fat cheddar, but you could swap the cheddar for mozzarella or Parmesan, or even a mixture of them.

Serving Suggestions

We went with linguine, as it's a classic, and the creamy leek sauce clings really well to it. But, you could use any of your favourite pasta shapes.

You don't have to serve this with pasta, it is equally delicious spooned over some homemade mashed potato. We have also used it as a topped for steak and grilled chicken breast, and I might try it on grilled salmon next too. So many options!
