2 tablespoons unsalted butter: Adds richness to the béchamel sauce.

3 cloves garlic (minced): A fragrant punch that amps up the savory notes.
2 tablespoons all-purpose flour: The thickening agent for the creamy sauce.
1.5 cups milk (whole or 2%): Creates the smooth, luscious base of the sauce.

½ cup grated parmesan cheese: Adds a salty, nutty savoriness, plus a little extra for serving.
½ teaspoon black pepper: For a touch of heat balanced with aromatic warmth.
½ teaspoon kosher salt + more: Essential for seasoning both the pasta water and dish.

½ cup reserved pasta water: Perfect for adjusting sauce consistency.
¼ cup water: Used to deglaze the pan if necessary while cooking mushrooms.
2 tablespoons olive oil: For browning the breadcrumbs.
1 teaspoon dried rosemary: Infuses the walnut breadcrumbs with a fragrant, woodsy aroma.

1 cup raw walnuts: Ground to add nutty crunch and richness to the topping.
½ cup panko bread crumbs: Light and crispy, perfect for that crunchy topping.
½ teaspoon coarse sea salt: Highlights the flavors in the breadcrumbs.

1 teaspoon Aleppo pepper: Adds a mild fruity heat with subtle smokiness.

How to Make Creamy Shiitake Mushroom Pasta with Rosemary Walnut Breadcrumbs Recipe

Step 1: Make the Rosemary Walnut Breadcrumbs

Start by pulsing the walnuts in a food processor just until crumbly — avoid over-processing to keep the texture perfect. Heat olive oil over low to medium-low heat, then add dried rosemary and let it bloom in the oil for 10 to 15 seconds to release its fragrant oils. Toss in the walnuts and stir constantly for about 4 to 5 minutes, being careful not to let them burn. Next, add the sea salt, garlic powder, nutritional yeast, black pepper, Aleppo pepper, and panko bread crumbs. Keep stirring until the breadcrumbs turn a lovely light golden brown. Remove from heat and set aside to cool, savoring that incredible aroma.

Step 2: Cook the Pasta

Bring a large pot of water to a rolling boil and salt it generously — think sea water salty, so the pasta absorbs flavor from within. Cook the pasta according to package instructions until al dente, reserving a cup of pasta water before draining. This starchy water will be your secret weapon to smooth and perfect your sauce.

Step 3: Cook the Mushrooms and Make the Béchamel Sauce

Heat olive oil in a large skillet over medium-high heat and add the sliced shiitake mushrooms, minced garlic, and a pinch of salt. Sauté until mushrooms are golden and their moisture has evaporated, about 5 to 6 minutes. Push the mushrooms to one side of the pan, reduce heat to medium-low, and add butter to the empty side. Once melted, whisk in the flour and cook for about one minute to cook out the raw flour taste. Gradually pour in the milk, whisking constantly for a smooth béchamel sauce. Stir the mushrooms back in and let everything simmer gently, stirring occasionally, until the sauce thickens, around five minutes.

Step 4: Combine Pasta and Sauce

Remove the skillet from heat and fold in the parmesan cheese, which will melt beautifully into the sauce. Add the drained pasta and toss everything together until every piece is coated. Use the reserved pasta water little by little to loosen the sauce if it feels too thick, keeping in mind it will thicken more as it cools.

Step 5: Finish with the Rosemary Walnut Breadcrumbs

Serve the pasta warm, generously topping each portion with those crunchy, aromatic rosemary walnut breadcrumbs. Their textural contrast and herbaceous punch make this dish unforgettable.

Garnishes

A sprinkle of fresh parsley or thyme helps brighten the earthy creaminess, while an extra dusting of parmesan adds richness. A few torn basil leaves can lend a vibrant pop of green and freshness that plays beautifully with the deep mushroom flavors.

Side Dishes

This pasta pairs wonderfully with a crisp green salad tossed with tangy vinaigrette to cut through the richness. Roasted or steamed seasonal vegetables like asparagus or broccoli also complement the dish with added texture and color.

Creative Ways to Present

Serve this pasta in rustic ceramic bowls to emphasize its comforting appeal. For an elevated touch, drizzle a bit of truffle oil before adding the breadcrumbs or gently fold in sautéed spinach to the sauce for extra earthiness and nutrition.

Make Ahead and Storage

Storing Leftovers

Store any leftover Creamy Shiitake Mushroom Pasta with Rosemary Walnut Breadcrumbs Recipe in an airtight container in the refrigerator for up to three days. To keep the breadcrumbs crunchy, store them separately and sprinkle on just before serving again.

Freezing

This pasta doesn’t freeze as well once mixed due to the delicate creamy sauce and walnut breadcrumbs, which may lose texture. If you want to freeze, do so before combining with sauce, freezing the cooked pasta separately, and thawing before reheating with sauce freshly made.

Reheating

Reheat gently on the stovetop over low heat, adding a splash of milk or reserved pasta water to loosen the sauce as it warms. Avoid microwave reheating if possible to prevent drying out. Add reserved or fresh rosemary walnut breadcrumbs only after reheating for best texture.

FAQs

Can I use other types of mushrooms?

Absolutely! While shiitake mushrooms provide a lovely deep flavor, cremini, portobello, or button mushrooms can be delicious substitutes. Just adjust cooking time slightly depending on the mushroom type.

What if I don’t have nutritional yeast?

Nutritional yeast adds a cheesy umami flavor to the breadcrumbs, but it’s optional. You can skip it or replace with a bit more parmesan cheese if you prefer.

Is this recipe vegan-friendly?

This particular recipe includes butter, parmesan, and milk, which are not vegan. However, you can swap them for plant-based alternatives like vegan butter, dairy-free cheese, and oat or almond milk to make a delicious vegan version.

How do I make the breadcrumbs extra crispy?

Use panko bread crumbs for the best crunch and toast them slowly over low heat with plenty of stirring to avoid burning. Don’t rush the toasting process, and add the walnuts toward the end to retain their crunch.

Can I use fresh rosemary instead of dried in the breadcrumbs?

Yes, but use fresh rosemary sparingly since it’s more potent and can be woody. Chop it finely and consider slightly reducing the amount to avoid overpowering the walnuts.
