Instructions

Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta and cook until al‑dente, about 1 minute less than package instructions. Drain, reserving ½ cup cooking water, and set aside.

Pro Tip: Toss the hot pasta with a drizzle of olive oil to prevent sticking before mixing with the sauce.

Sauté Mushrooms & Garlic

Heat olive oil in a large skillet over medium‑high heat. Add sliced mushrooms, spreading them in a single layer. Cook without stirring for 3‑4 minutes until they brown, then stir and add garlic; sauté another minute until fragrant.

Pro Tip: Let mushrooms sit undisturbed; this encourages caramelization and richer flavor.

Create the Cream Sauce

Deglaze the pan with white wine, scraping browned bits. Reduce by half, then stir in heavy cream, reserved pasta water, thyme, and a pinch of nutmeg. Simmer 3‑4 minutes until the sauce thickens slightly; season with salt and pepper.

Pro Tip: Adding a splash of pasta water helps the sauce cling to the noodles.

Combine Pasta & Sauce

Toss the cooked pasta into the skillet, ensuring each strand is coated. Transfer the mixture to a greased 9‑x‑13‑inch baking dish. Sprinkle mozzarella evenly, followed by parmesan, creating a uniform cheesy crust.

Pro Tip: For extra crunch, add a thin layer of panko breadcrumbs on top.

Bake to Perfection

Preheat oven to 375°F (190°C). Bake the casserole for 20‑25 minutes, until the cheese is melted, bubbling, and the edges turn a deep golden brown. Let rest 5 minutes before serving.

Pro Tip: A brief rest allows the sauce to set, making slices cleaner.

Expert Tips

Tip #1: Use a Mix of Mushrooms

Combining cremini, shiitake, and button mushrooms adds layers of texture and umami, making the sauce richer without extra seasoning.

Tip #2: Cool the Sauce Slightly

Before mixing with pasta, let the cream sauce cool 2‑3 minutes; this prevents the cheese from melting too quickly and forming a greasy layer.

Tip #3: Finish with Fresh Herbs

A sprinkle of fresh parsley or chives just before serving brightens the dish and adds a pop of color without overwhelming the creamy base.
