Key Ingredients

A few specialty ingredients give this recipe its signature flavor, but I’ve also included simple substitutions so you don’t have to hunt down hard-to-find items.

Cremini mushrooms- Ina recommends half cremini and half shiitake. Several tasters found the shiitake mushrooms too chewy, so I’ve since been using only cremini and we love it.

Cream sherry- Sherry is added to the mushrooms after they’re cooked for a nice sweetness. Can’t find cream sherry? No worries. I’ve included an easy substitution in the recipe notes below that works beautifully with dry sherry.

Pasta- Cavatappi is recommended but any favorite pasta shape will do.

Scalded milk- Scalded milk or milk heated to the desired temperature in the microwave, provides the same outcome.

Nutmeg- A small amount of nutmeg is added so it’s not forward-tasting, but a classic addition to many macaroni recipes.

Bread crumb topping- The topping is made using white bread, fresh garlic, and fresh parsley. Perfect for a subtle crunch in most every bite.

Two Ingredients That Make This Truffle Macaroni and Cheese Special

To capture the rich, indulgent flavor of Ina Garten’s Truffled Mac and Cheese, these two ingredients are essential:

White Truffle Butter:
This luxurious ingredient adds a deep, earthy, and slightly musky flavor that sets this dish apart from any other mac and cheese. While white truffle butter can be tricky to find, it’s worth seeking out if you’re able.

Gruyère and Extra-Sharp Cheddar:
The cheese blend is key to the creamy, bold flavor of this dish. Gruyère brings a nutty, slightly sweet richness, while extra-sharp cheddar adds the perfect bite and tang. Together, they create an ultra-smooth and flavorful cheese sauce that coats every piece of pasta.

How to Make Truffle Mushroom Mac and Cheese

Don’t let the gourmet flavors fool you. The recipe comes together in a few simple stages, and once you’ve made it once, it’s surprisingly easy. The process is easier than you might expect, especially if you prep the mushrooms and grate the cheese before you begin.

Saute the mushrooms- Mushrooms get sautéed before being added to the Truffle Macaroni and Cheese. Ina says to cook until “tender” but we like our mushrooms browned pretty well. The mushrooms don’t really cook much further while baking in the oven so I’d saute them to your liking.

I cooked my mushrooms until they’re dark around the edges plus a good many of them are caramelized. You can leave out the mushrooms if anyone in your family doesn’t like them. They add a nice complexity to the texture of the dish.

Cook your pasta- Ina recommends cavatappi pasta and I’ve used it every time I make this mac and cheese because it’s substantial and ridged so it holds the creamy cheese very well. Plus, it’s a cool shape. But any ridged pasta will work well if you can’t find cavatappi- Ziti, penne, rigatoni, large elbow (though not ridged, this is classic mac and cheese pasta), or twisty fusilli.

White truffle butter is what transforms this from an ordinary macaroni and cheese into something truly special. Its earthy, savory flavor is subtle rather than overpowering, adding richness to every bite. If you can’t find white truffle butter, don’t worry—I share a few easy substitutions below. Note: white truffle butter is more mild than black truffle butter and if you try to use black truffle butter or oil instead, the flavor will be brighter. Either type of truffle may be used.

White Truffle Butter Substitutes for Truffled Mac and Cheese

White truffle butter gives this recipe its signature earthy flavor, but it isn’t always easy to find outside specialty grocery stores. Fortunately, there are a couple of easy substitutions that still make a delicious truffle mac and cheese.

1. Truffle Oil + Salted Butter:
Truffle oil is more widely available and can be found in most major supermarkets. To replace the 4 ounces of white truffle butter in the recipe, use:

• 2 tablespoons truffle oil

• 2 tablespoons salted butter
  This combo gives you that earthy truffle flavor with a creamy base that melts beautifully into the sauce.

2. Garlic and Black Pepper:
If truffle products aren’t available, mimic the flavor with common pantry staples. Truffle has notes similar to garlic and pepper, so try:

• 4 minced garlic cloves (or 2 teaspoons garlic paste)

• ½ teaspoon freshly ground black pepper

• 4 ounces salted butter
  While not an exact match, this blend adds a rich, savory depth that works wonderfully in the recipe.

Making the truffle cheese sauce-

The truffle butter is melted before adding the other ingredients for the cheese sauce.

All-purpose flour is then sprinkled onto the melted butter and cooked to remove the raw flour taste. I’m showing this picture where the flour has clumped quite a bit which may happen as you stir it. Not to worry, this will eventually smooth out when mixed with the hot milk. If you can’t completely smooth it out at this point, it will come out of the oven perfectly creamy so don’t fret about it.

Hot or scalded milk is added to the flour and stirred until the mixture becomes thick and creamy.

Gruyere and extra sharp cheddar are a perfect balance in the recipe. Gruyere can be pricey but it’s so full of flavor and melts incredibly well that it’s worth paying for. The high water to fat content in this cheese helps the cheese to melt without separating. It can seem a bit “stinky” before melting but stick with it. Extra sharp cheddar pairs well with the Gruyere and the sharp tang it provides is uncompromised and just right when baked and incorporated in this recipe.

Stir the cheese sauce until all the cheese is melted before combining the other ingredients.

Prepare the macaroni and cheese for the oven-

In the pot you cooked the pasta, add the cheese sauce, mushrooms, and pasta, stirring until fully incorporated. Then transfer to the baking dish for the oven.

White bread, fresh garlic cloves, and fresh parsley make the perfect topping for this macaroni and cheese.

After the breadcrumb topping is added, placing some reserved mushrooms on top makes a nice presentation.

Tips for the Creamiest Mac and Cheese

A few small techniques make all the difference when making homemade cheese sauce.

• Grate your own cheese for the smoothest sauce.
• Heat the milk before adding it to the roux.
• Don’t overcook the pasta before baking.
• Let the cheese sauce cool for a minute before adding the pasta if it becomes extremely thick.
• Brown the mushrooms well for maximum flavor.
• Allow the casserole to rest for 5–10 minutes before serving.

Variations and Easy Substitutions

This recipe is flexible enough to work with what you have on hand.

• Use truffle oil plus butter if truffle butter isn’t available.
• Dry sherry can be substituted for cream sherry (see notes).
• Penne, cavatappi, rigatoni, or large elbows all work well.
• Leave out the mushrooms if serving someone who doesn’t enjoy them.
• Add cooked pancetta or bacon for extra richness.

What to Serve with Truffle Mushroom Mac and Cheese

Although hearty enough to stand on its own, this mac and cheese pairs beautifully with roasted meats, grilled steak, roasted chicken, pork tenderloin, or salmon. A crisp green salad or simply roasted vegetables help balance its rich, creamy flavor.

Storage and Reheating

This macaroni and cheese reheats beautifully, making leftovers something to look forward to.

• Refrigerate in an airtight container for up to 3 days.
• Freeze for up to 2 months.

Reheat covered in a 350°F oven until hot throughout, or microwave individual servings with a splash of milk to loosen the sauce.

Frequently Asked Questions

Can I make this ahead of time?

Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Let it sit at room temperature for about 30 minutes before placing it in the oven.

Can I freeze macaroni and cheese?

Yes. Cool completely before wrapping well and freezing for up to 2 months. Thaw overnight in the refrigerator before reheating.

Can I use truffle oil instead of truffle butter?

Absolutely. Truffle oil combined with butter makes an excellent substitute and still gives the dish its signature earthy flavor.

What mushrooms work best?

Cremini mushrooms are my favorite because they have great flavor and hold their texture well after baking.

Can I prepare this without mushrooms?

Yes. The mushrooms add wonderful depth, but the cheese sauce is delicious on its own.

Whether you’re serving this Truffle Mushroom Mac and Cheese for a holiday gathering or a cozy weekend dinner, it’s one of those recipes that always feels a little extra special. The combination of creamy cheese, savory mushrooms, crisp breadcrumbs, and subtle truffle flavor makes every bite worth slowing down for. I hope it becomes a favorite in your kitchen, too.
