The Star Ingredients

King Oyster Mushrooms: These mushrooms mimic the tender-chewy texture of sea scallops. Often called trumpet mushrooms, they’re available at Asian or international groceries and are usually affordable. The thick, meaty stalk is the best part—great grilled, seared, fried, shredded, or sautéed. They work beautifully in pastas, stews, stir-fries, tacos, noodles, and soups.

King oyster mushrooms offer antioxidants, B vitamins, zinc, potassium, fiber, and a modest amount of protein. Their flavor is earthy, umami-rich, and slightly nutty.

The Pasta: Choose a high-quality pasta that holds a firm, al dente bite. Long shapes work especially well with creamy sauces; bucatini or other thick spaghetti are good options. Gluten-free pasta can be used if preferred.

Pasta Cooking Water: Save at least 2 cups of the starchy pasta water. We’ll use about 1/2 cup in the sauce and more if you want a looser finish. The starch helps thicken the sauce and helps it cling to the noodles.

Sauce Ingredients

Miso: Miso is a small but powerful secret ingredient in this sauce. It adds depth, umami, and savory richness similar to MSG but naturally fermented. Use mellow (yellow) miso or chickpea miso for a balanced flavor.

Nutritional Yeast: Nutritional yeast plus miso create a cheesy, savory base perfect for a vegan cream sauce. It lends a nutty, cheesy flavor without dairy.

Non-Dairy Milk: Plain, unsweetened soy milk is my top pick for creaminess and neutral flavor. Oat milk or homemade cashew milk also work well. Avoid sweetened or flavored milks and skip coconut milk for this recipe.

How to Make It

Cook the Pasta

Step one: Cook pasta according to package directions. Tip: use a large pot and heavily salted water — about 2 tablespoons kosher salt — to season the noodles. Stir the pasta for the first 30 seconds after adding it to the pot to prevent sticking and help the starch release. Drain and toss with a little extra virgin olive oil to keep noodles from clumping.

Prepare the Mushrooms

Step two: Trim the tough lower 1–1.5 inches of the king oyster mushroom stalk, then slice into 1–1.5 inch medallions. You can leave the cap attached if you like. Score the cut sides in a shallow checkered pattern with a paring knife to help them absorb flavor.

Step three: In a large cast iron or heavy skillet, melt 2 tablespoons vegan butter over medium-high heat. Add mushrooms cut-side down, sprinkle with garlic powder and sea salt, then place a heavy lid or another skillet on top. This presses the mushrooms and helps draw out liquid, creating a meaty texture. Cook for about 8 minutes.

Remove the lid, add minced garlic to the pan liquid, and flip the mushrooms with tongs. The cooked side should be golden and slightly crispy. Continue cooking 5–10 more minutes until both sides are golden and mushrooms are tender. Avoid burning the garlic. Remove the mushrooms but leave the sautéed garlic and pan fond to build the sauce. Keep mushrooms warm in a low oven if needed.

Make the Sauce

Step four: In the same pan with the garlic and fond, add 2 tablespoons extra virgin olive oil. Immediately sprinkle in 1 tablespoon all-purpose flour and toast on medium-low until slightly tan (if using cornstarch, do not toast). Whisk in 1 cup plain unsweetened soy milk, 1/2 cup pasta water (reserve extra), 1 tablespoon nutritional yeast, and 1 tablespoon mellow miso. Break up the miso and whisk until the sauce is smooth. Bring to a gentle simmer and cook until creamy and thick. Add up to another 1/2 cup pasta water to loosen if desired.

Step five: Add the drained pasta to the sauce and use tongs to toss and coat every noodle. Taste and adjust seasoning with salt and black pepper. Finish with 2 teaspoons fresh lemon juice for brightness.

Garnish and Serve

Plate the creamy pasta and top with seared mushroom scallops. Sprinkle vegan walnut parmesan or nutritional yeast, chopped parsley, a squeeze of lemon, red pepper flakes if you like heat, and a crack of black pepper. Serve with a simple salad, roasted asparagus, or broccoli for a complete meal.

Tips for the Best Vegan Creamy Pasta

  • Salt your pasta water generously to season the noodles and the finished dish.
  • Stir pasta in the first 30 seconds to prevent sticking and to release starch.
  • Press mushrooms with a heavy lid or skillet while cooking to make them extra meaty.
  • Do not scrub the pan after cooking mushrooms — the browned bits add flavor to the sauce.
  • Toss pasta with tongs to ensure each strand is well coated.

How to Reheat

This pasta reheats well. Warm gently on the stove with a splash of plant milk or in the microwave until heated through.
