Preheat your oven to 180c (360f) and line a baking tray with parchment paper. Mix the breadcrumbs, smoked paprika and salt and set aside.
Peel both potatoes, cut one into 1 inch chunks and toss in 1 tablespoon of olive oil and a sprinkle of salt. Roast on the prepared baking tray for 20 minutes (don't over roast or it will dry out). Set aside.

Puree with a hand blender or blender with the nutritional yeast, miso paste, lemon juice, garlic powder, smoked paprika, salt and pepper. This is where you can add the ½ cup of oat milk, I do to just give it a looser texture.
Your vegetable mix might be warmer or cooler than mine so this is to taste. If it is really warm then add your milk in cold if it is on the cooler side then warm up your oat milk (or whatever milk you are using).
Don't overblend as it could turn into a starchy paste, stop blending when it is nicely incorporated.
Season to taste.
Boil your pasta according to package instructions for a minute or two less than what it says. It will keep cooking in the oven.
Drain and then mix in the sauce.
Put into an oven proof dish, top with the breadcrumbs and bake for 20 minutes until top is golden and the sauce is bubbling.
