- Smoked paprika: 1/2 teaspoon for warmth (regular paprika works too).
- Salt and black pepper: To taste.
- Olive oil or vegan butter: 2 tablespoons for richness.
- Tapioca starch or cornstarch: 1–2 tablespoons to help the sauce thicken and stretch.

Step-by-Step Instructions
- Soak the cashews: Cover cashews with hot water and soak for 20–30 minutes. Drain.For the creamiest result, soak for 2–3 hours in cool water or overnight.
- Cook the pasta: Boil in well-salted water until just shy of al dente (1–2 minutes less than package). Drain and set aside. Toss with a little olive oil to prevent sticking.
- Blend the sauce: In a high-speed blender, combine soaked cashews, 1 3/4 cups plant milk, nutritional yeast, miso, lemon juice, Dijon, garlic, onion powder, smoked paprika, tapioca or cornstarch, 1/2 teaspoon salt, and a few grinds of pepper.Blend until silky smooth.
- Adjust thickness: If using vegetable broth, add up to 1/2 cup and blend again, reducing plant milk slightly. The sauce should be pourable, like a thin Alfredo. It will thicken in the oven.
- Taste and tweak: Add more salt, lemon, or nutritional yeast if needed.For heat, sprinkle in chili flakes.
- Warm the sauce: Pour into a skillet over medium heat. Stir for 2–4 minutes until glossy and starting to thicken. Don’t let it boil hard.If too thick, whisk in a splash of plant milk.
- Combine with pasta: Preheat oven to 375°F (190°C). In a large bowl, toss pasta with the sauce. Fold in any veggies or add-ins.
- Assemble the bake: Transfer to a lightly oiled 9×13-inch baking dish.Smooth the top.
- Add the topping: Mix breadcrumbs, olive oil, a pinch of salt, and nutritional yeast. Sprinkle evenly over the pasta.
- Bake: Bake for 18–22 minutes, until bubbling at the edges and the topping is golden. For extra color, broil for 1–2 minutes, watching closely.
- Rest and serve: Let it sit for 5–10 minutes to set.Finish with fresh parsley, black pepper, and a squeeze of lemon if you like.
How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Freeze portions for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm in a 350°F (175°C) oven, covered with foil, for 15–20 minutes. Add a splash of plant milk if it seems dry.Microwave single portions in 60–90 second bursts, stirring in between.

- Skipping seasoning: Taste the sauce before baking. Adjust salt, lemon, and nutritional yeast for a balanced flavor.
- Letting the sauce boil hard:</-strong> High heat can cause separation. Gently warm and stir until thickened.
Variations You Can Try

- Gluten-free: Use gluten-free pasta and breadcrumbs.
FAQ
Can I make the sauce without a high-speed blender?
Yes. Soak cashews longer (4–6 hours) and blend in a regular blender until smooth.
You can also use a food processor, but strain the sauce through a fine mesh sieve if needed for extra smoothness.
What can I use instead of miso?
You can skip it or use 1 teaspoon soy sauce or tamari for a similar umami note. Taste and adjust salt afterward.
How do I make it oil-free?
Omit the olive oil and skip oil in the topping. Use a splash of vegetable broth to warm the sauce and top with crushed cornflakes or plain breadcrumbs without oil.
It won’t be as rich but still tasty.
Can I prepare this ahead of time?
Absolutely. Assemble the pasta and sauce in the baking dish, cover, and refrigerate for up to 24 hours. Add the breadcrumb topping right before baking.
You may need a few extra minutes in the oven.
Why did my sauce get clumpy?
It likely boiled too hard or too long. Keep the heat moderate and stir constantly as it thickens. If it tightens up, whisk in a splash of warm plant milk to loosen it.
Which pasta shape works best?
Short, ridged shapes like rigatoni, penne, or shells hold onto the sauce well.
Fusilli and cavatappi are also great for maximum creaminess in every bite.
Can I add vegan cheese shreds?
Yes. Stir in 1/2 to 1 cup along with the sauce for extra gooeyness. Choose a meltable brand and reduce the salt slightly.
Is nutritional yeast necessary?
It’s key for cheesy flavor, but if you don’t have it, add a bit more Dijon, lemon, and miso for complexity.
The result won’t be as cheesy, but it will still be delicious.
