This miso pasta sauce with cannellini beans and leeks is THE most delicious meal EVER. It is the dreamiest combination of textures and the umami flavor of miso paste adds a huge flavor bomb. The beans make it a creamy sauce without any cream and makes it easily adapted to be vegan. This recipe will have you licking your plates clean, I guarantee it.
Hi! This is my first recipe of 2024 can you believe it?! This is a recipe I have adapted from plant based food blogger Nat's Nourishment. Her reel on instagram stopped me in my tracks and I knew I had to turn her leek and bean dish into a pasta. I have stayed pretty true to her recipe with a few BBT tweaks here and there.
I have used a hand rolled gnocchi sardi for this dish which I think adds such a lovely textural contrast to the soft beans and leeks. You could use any shape you like fresh or dried. If you have never used miso paste in a pasta before, don't be scared! It adds such an amazing depth of flavor. You'll have to make my Creamy Miso Mushroom Pasta next!
Leeks - I had to use two small ones so if you find a really big one that should be enough.
Onion - If you follow me on instagram you know that when I recently travelled to the USA I was SHOCKED at how big the onions were. I used ½ a onion so maybe even use a ¼ if you are there.
Garlic - Fresh garlic cloves are the best option, jarred garlic is just not the greatest for cooking, it has a strange preserved flavor in my opinion.
Cannellini beans - You could also use any other kind of white beans like butter beans. Try and find a can that has no salt added. If you can't and they are in normal brine you might just need to watch your seasoning.
White miso paste - Miso is a fermented soy bean paste used in Japanese Cuisine, you've probably tried miso soup before. The colour name is a bit confusing as the white paste is still quite brown in colour. It's really easy to find in supermarkets now and usually comes in a tub. You can get red miso paste too but I haven't tested that with this sauce.
Fresh rosemary - I think miso and rosemary are a match made in heaven. You could substitute for thyme if you wish.
Fresh lemon juice - Lemon freshens up any pasta sauce, it cuts through the salty miso perfectly in this sauce.
- Weigh your pasta portions! This is always one of my biggest tips. It ensures the perfect pasta to sauce ratio and literally takes less than a minute. I suggest 100 grams dried per person or 150 grams fresh per person.
- Be careful when flipping the leek rounds over but it also really doesn't matter if they come apart.
- If you are unsure of the miso start with less and you can always add more.
- Use a large skillet that the pasta will fit into at the end.
- Undercook your pasta! If using dried pasta, undercook it by a minute so it can finish cooking in the sauce and still be al dente. By letting pasta bubble away in the sauce you allow the pasta to take on flavor and it helps thicken the sauce too.
- Reserve some starchy pasta water. I tend to transfer the cooked pasta straight into the sauce with a spider strainer so the water is left in the pot to use as I need.
How to make this miso pasta
Full ingredient list and method (plus a short tutorial video) is in the recipe card below.
ONE: Over a medium heat fry the leek rounds in extra-virgin olive oil and butter for 4 - 5 minutes until golden brown. Set aside.
TWO: In the same large skillet gently fry the onion for 3-4 minutes.
THREE: Add the garlic and cook for a further minute.
FOUR: Add the cannellini beans as well as all the liquid in the can and bring to a very gentle simmer.
FIVE: Add the miso, lemon juice and rosemary and stir through. Miso is quite a thick paste so mix it with a couple of tablespoons of hot water first if you wish.
SIX: Add your cooked pasta along with ¼ cup of pasta water.
SEVEN: Let the pasta simmer in the sauce very gently on a low heat for a minute or so. Add a splash more pasta water if you need.
EIGHT: Add the cooked leeks back in and gently stir through. Add in a knob of butter (optional) and serve with lemon zest and parmesan cheese and black pepper to finish.
Absolutely! Just use a vegan butter to fry the leeks and again at the end (or leave the final butter out). Most dried pasta is naturally vegan but I am sure you'll know the ones you always use are.
No! The soaking liquid they are in is actually the basis of the sauce so tip it all in. That is why I suggest finding a 'no salt added' can so you can control the seasoning yourself.
I don't like rules so use any type of pasta you like but I personally think a short pasta shape works best here.
I never think pasta reheats particularly well but this will keep in an airtight container in the fridge for 2 - 3 days.
