Ingredients You’ll Need

This recipe relies on quality, fresh ingredients that balance creamy, earthy, and crispy textures perfectly. When shopping, look for good melting cheeses and fresh mushrooms to get the best flavor.

• Small shell or elbow pasta: These shapes hold the sauce well, but you can experiment with cavatappi or rotini too.
• Mushrooms (cremini, shiitake, oyster, chanterelle, porcini, maitake): A mix adds depth and earthiness, but use what’s freshest and your favorite types.
• Onion: Diced finely — it mellows and adds a little sweetness when sautéed with mushrooms.
• Olive oil: The base for sautéing, and you can swap for butter if preferred.
• Fresh thyme: Adds a lovely herbal aroma that pairs beautifully with mushrooms and cheese.
• Butter: For the sauce base — gives richness, but olive oil works if you want dairy-free.
• Flour: Creates the roux to thicken the cheese sauce.
• Milk (whole or half & half): Creamy liquid for the sauce — whole milk keeps it lush without being heavy.
• Gruyere or white cheddar cheese: Use sharp, melty cheeses for a rich, smooth texture and flavor.
• Pecorino cheese: Adds salty, nutty notes both in sauce and topping.
• Salt and pepper: Essential seasonings — don’t skip or underestimate!
• Dijon mustard: Elevates the cheese sauce with subtle tang and depth.
• Nutmeg: Just a pinch adds warmth and rounds out the sauce flavor.
• Truffle oil: The star ingredient for that signature earthy, aromatic punch — add gradually to taste.
• Panko breadcrumbs: Creates the crispy topping that contrasts perfectly with creamy pasta.
• Optional chopped spinach: Sneaks in some greens and adds freshness if you want.

Variations

I love how flexible this Truffle Mushroom Mac and Cheese Recipe is, so feel free to make it your own. You can swap cheeses, mushroom varieties, or even add in some protein for a heartier version.

• Cheese Variations: I’ve used sharp white cheddar mixed with gruyere for a stronger bite or even fontina for extra creaminess — both work wonderfully.
• Mushroom Swaps: Cremini and shiitake are my go-tos, but chanterelles or maitake add a wild, woodsy flavor that’s amazing for mushroom lovers.
• Make it Vegan: Use a plant-based milk and vegan cheese alternatives, then substitute olive oil for butter to keep it dairy-free but still rich.
• Add Protein: Toss in cooked pancetta, sautéed chicken, or even crispy tofu cubes to turn this into a complete meal.
• Extra Greens: Spinach, kale, or even roasted asparagus folded in add color and a fresher taste that contrasts the richness.

How to Make Truffle Mushroom Mac and Cheese Recipe

Step 1: Cook the Pasta Perfectly

Start by bringing a large pot of salted water to a boil and cook your choice of pasta just until al dente—this means it should still have a little bite because it’ll cook more in the oven later. Once cooked, drain well and rinse briefly with cold water to stop the cooking and prevent sticking. Toss the pasta back into the pot with a drizzle of olive oil and stir gently — this simple step keeps your noodles loose and ready to soak up that delicious cheese sauce evenly without clumping.

Step 2: Sauté the Mushrooms and Onions

While the pasta cooks, heat olive oil in a large skillet over medium heat and add your mushrooms alongside diced onions. Cook gently, stirring occasionally so they soften and release their flavor without burning. Season with salt, pepper, and fresh thyme to bring out that earthy aroma. This base will add incredible depth, so don’t rush—let the mushrooms brown slightly but stay tender and juicy.

Step 3: Make the Creamy Truffle Cheese Sauce

This part is my favorite because you get that velvety, nutty sauce that makes this dish unforgettable. Melt butter over medium heat until it turns golden brown and smells wonderfully nutty—this brown butter base takes your sauce to the next level. Whisk in flour and cook for about a minute to get rid of the raw taste, then gradually add milk while whisking constantly to avoid lumps. Keep stirring until the sauce thickens slightly, then reduce heat. Now it’s time to stir in shredded gruyere, pecorino, Dijon mustard, salt, pepper, nutmeg, and fresh thyme. When everything melts together smoothly, turn off the heat and gently fold in truffle oil—start with a small amount and add more cautiously because a little goes a long way here!

Step 4: Combine Pasta, Sauce, and Mushrooms

Pour the luscious cheese sauce over your cooked pasta in the pot and fold in two-thirds of the sautéed mushrooms, reserving some for garnish on top. If you want, add a handful or two of chopped spinach to sneak in some greens—this always makes me feel a little less guilty about indulging. Give everything a taste test and adjust salt, pepper, or more truffle oil until it sings just right to your palate.

Step 5: Prepare the Crispy Topping and Bake

Mix panko breadcrumbs, pecorino cheese, fresh thyme, and olive oil or extra truffle oil in a small bowl for that irresistible crunchy topping. Butter a 9 x 13-inch baking dish, transfer your mac and cheese mixture inside, then sprinkle the panko topping evenly over the surface. Pop it in a preheated 375°F oven and bake uncovered for 15 minutes until the topping starts to crisp up. Add the remaining mushrooms on top and continue baking for 10-15 minutes more until the entire dish is bubbly, golden, and absolutely mouthwatering.

How to Serve Truffle Mushroom Mac and Cheese Recipe

Garnishes

I always add a scattering of reserved sautéed mushrooms on top right before the last bake to brighten the presentation and punch up the mushroom flavor. A sprinkle of fresh thyme or chopped chives adds a subtle freshness and color that makes it feel elevated. Sometimes I finish with a light drizzle of truffle oil just before serving if I’m feeling extra fancy.

Side Dishes

I love pairing this mac and cheese with crisp green salads dressed simply with lemon vinaigrette to cut through the rich cheese. Roasted vegetables like Brussels sprouts or asparagus provide a nice, earthy contrast. For a heartier meal, a side of garlic bread or a light tomato-based soup complements the creamy pasta beautifully.

Creative Ways to Present

For special occasions, I’ve baked this recipe individual-style in small ramekins topped with sautéed mushrooms and crispy breadcrumbs — it’s charming and perfect for dinner parties. You can also swirl in a vivid beet or carrot purée on the plate for a splash of color or serve alongside truffle popcorn for a playful appetizer vibe.

Make Ahead and Storage

Storing Leftovers

I like to store leftovers in an airtight container in the fridge and usually enjoy them within 2-3 days for the best flavor and texture. The sauce thickens as it sits, so before reheating, I loosen it up with a splash of milk or cream to bring back that creamy consistency.

Freezing

You can freeze this mac and cheese, but I recommend skipping the breadcrumb topping before freezing to keep it from getting soggy. Freeze it in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating for the best results.

Reheating

I gently reheat leftovers in the oven at 325°F, covered with foil to prevent drying out, or heat in a skillet on low with a little splash of milk. Microwaving works in a pinch but can make it uneven—stir often to keep things creamy and smooth.
