Ingredient Breakdown
Pasta : Pasta is the foundation of this dish! For this recipe, I prefer 8 oz of your favorite pasta, spaghetti, penne, or even gluten-free varieties all work great. The best part is, you can use whatever shape you have on hand! Cook it according to the package instructions until it’s al dente. Fresh or frozen pasta works well too if you’re in a pinch.
Cannellini Beans : One can of cannellini beans, drained and rinsed, packs a protein punch and adds creaminess to the sauce. They’re super versatile, if you don’t have cannellini, white kidney beans or chickpeas will work beautifully too! Plus, they make this sauce extra comforting.
Leek : The star of the show! One leek, sliced, brings a mild, sweet onion flavor that adds depth to the sauce. I really love using leeks because they’re a bit more refined than regular onions, giving the dish a gourmet flair. If you’re out and about, go ahead and substitute with green onions or shallots!
Miso Paste : You’ll need 2 tablespoons of miso paste for that umami burst. Miso is like magic in a jar, it enhances the flavor of everything! White miso is milder and sweeter, while red miso gives a richer, saltier flavor, so you can choose based on what you have. Honestly, you can’t really go wrong!
Olive Oil : 1 tablespoon of olive oil is all you need to sauté the leeks and garlic, filling your kitchen with irresistible aromas. I prefer using high-quality extra-virgin olive oil here for added flavor. If you’re looking for something light, grapeseed or avocado oil will do the trick too!
Garlic : You can’t go wrong with 2 cloves of minced garlic in this dish! The fragrant aroma when garlic is cooking? Seriously unbeatable. If you’re a garlic lover like me, feel free to add more, there’s no such thing as too much garlic in my book!
Salt and Pepper : You’ll want to season the dish with a couple pinches of salt and pepper to taste. Adjusting the seasoning is super important; it brings all the flavors together! So taste as you go, and add more if necessary!
Fresh Herbs (Optional)
Let’s Get Cooking!
How to Make Miso Pasta Sauce with Cannellini Beans and Leeks
First, let’s get that pasta going! Cook the pasta according to the package instructions until it’s al dente, usually about 8-10 minutes. Drain and set aside.
While the pasta is cooking, heat 1 tablespoon of olive oil in a large pan over medium heat. Add the sliced leeks and sauté for about 3-4 minutes until they’re nice and soft and just starting to turn translucent.
Then, toss in the minced garlic and cook for another 1-2 minutes until fragrant, watching carefully so it doesn’t burn! Stir occasionally and scrape the yummy bits off the bottom of the pan for extra flavor. Seriously, that’s where the magic is!
Next, add in the drained cannellini beans and 2 tablespoons of miso paste, stirring everything together until well-combined. If the mixture seems a bit thick, don’t hesitate to add a splash of water to reach your desired sauce consistency.
Now, toss in the cooked pasta and mix everything thoroughly, coating it in that lovely miso sauce. Season with a couple pinches of salt and pepper to taste. You want the flavors to sing!
Serve hot! I love to garnish with fresh herbs if I have them on hand. It just makes everything look and taste that much better. Dive in and enjoy your masterpiece!
