Rich, Decadent, & Creamy Side Dish

I don’t care what anybody says, potatoes are the kings of side dishes. When it comes to potato recipes, the options are truly endless. And incredibly delicious.

I’m talking baked potatoes, roasted potatoes, french fries, smashed potatoes, hash browns, potatoes au gratin, and so much more.

Like the tried & true favorite – mashed potatoes. Now mashed potatoes are of course a classic dish and a fan favorite. But when it comes to classics, sometimes they become a little tiny bit boring.

That is where Truffle Mashed Potatoes come in! They are a delicious, unique, and flavorful spin on the beloved dish.

Truffle oil bring the creamy potato side to whole new levels with its deep, savory flavor. The result is a rich, decadent, and luxurious dish that will impress anyone you serve it to.

Ingredients

This side dish recipe only calls for a handful of simple ingredients! The use of truffle oil instead of real truffles makes it an affordable way to enjoy the luxurious flavor too.

Ingredient Notes

  • Potatoes: The base of this decadent recipe is of course potatoes! You will need 3 lb of a starchy type. I used russet potatoes!
  • Butter: Butter is another key element here. It helps add the richness and creaminess we all love in the classic mashed potato side. You’ll need 8 tbsp salted butter in total.
  • Milk: 2/3 cup whole milk also helps make these potatoes as creamy as can be.
  • Parmesan Cheese: I think parmesan cheese truly brings this dish to the next level. It pairs perfectly with the delicious truffle flavor. Add 1/2 cup! Or more if you’d like.
  • Truffle Oil: White truffle oil is what sets this recipe apart! It adds such a strong, delicious, deep, and earthy flavor here. You will need 2 tbsp. A little bit goes a long way!
  • Salt & Pepper: Add salt and pepper to taste to this recipe.
  • Fresh Chives: Fresh chives are optional but make for both a beautiful garnish and tasty addition. Plus they add a lightness and freshness that I love!

Substitutions & Additions

There are a few substitutions and additions you could make to this recipe in order for it to meet your personal needs, preferences, or tastes!

Potatoes: If you would like, you could use a different type of potato in this recipe. I recommend using another starchy one like Idaho or Yukon gold potatoes. They are the best for mashing!

Truffle Oil: I used the oil from white truffles in this recipe, but if you are looking for an even stronger flavor perhaps try out black truffle oil.

Butter: You could swap the salted butter here for unsalted butter. That way you can control the amount of salt in the recipe better!

Milk: I find whole milk to make these mashed potatoes creamy enough, but if you want even creamier try heavy cream or half & half.

Seasonings: For more flavor try adding garlic powder, onion powder, dried herbs, or truffle salt.

Herbs: I love fresh chives here, but fresh parsley or green onions would be great options too.

These creamy mashed potatoes are the perfect side dish for any holiday or dinner! They are super easy to whip up and will be ready to enjoy in no time.

Step By Step Instructions

Step 1: First peel the potatoes.  Then place in a large pot of salted water.  Boil for about 20-30 minutes or until fork tender.

Step 2: Once they are soft, drain potatoes. Add the hot potatoes to a large bowl or back into the pot they were boiled in (to keep warm).  Add in 6 tbsp softened butter and warm milk.  Mash potatoes with a potato masher.  Or use an electric mixer! (See my tips for why)

Step 3: Then add in the parmesan cheese and truffle oil.  Mix or mash the potatoes again until thoroughly combined, smooth, and creamy.

Step 4: Add salt and pepper to taste.

Step 5: Transfer to a serving or baking dish.  Top with the remaining 2 tbsp butter, an extra drizzle of truffle oil, cracked black pepper, and fresh chives.

Step 6: Serve and enjoy!

Expert Tips

Boil the potatoes in heavily salted water. This will just add more deliciousness to the final dish.

Leave the potatoes whole when boiling. This helps them keep their starchiness, which in turn makes them creamier when mashed.

Drain the potatoes thoroughly. Leaving water will make for watery, not creamy potatoes.

Mash the potatoes in the pot they were boiled in. This will prevent you from messing another dish and keeps the potatoes warm too.

Heat milk before adding to the cooked potatoes. This helps keep the dish warm and mixes in better.

Add softened butter, not melted. This provides a better flavor.

Use an electric mixer. This makes for ultra creamy potatoes! And is so much easier than mashing with a potato masher.

Use freshly grated parmesan cheese. It will melt way better into the potatoes.

Taste the potatoes as you go. Add small amounts of seasonings and truffle oil and taste along the way so you get it just right.

Frequently Asked Questions

What are truffles?

Truffles are a type of fungi! They are also a delicious chocolate dessert treat, puppy chow truffles, but that is not what we are talking about here. Lol!

This type of mushroom grows underground, typically in Italy. The most common types are either white or black truffles.

They are an expensive ingredient typically used in fancy dishes. They are expensive because they are scarce – hard to grow and very seasonal.

These savory truffles are great in pastas, sauces, and meats.

Where can I find truffle oil?

You may be able to find truffle oil in your local grocery store, but if not it is super easy to buy online. Here is the exact kind I bought from Amazon.

It is relatively affordable when it comes to the rich, fancy ingredient. It can also be used in so many delicious ways. Like truffle fries or truffle mac & cheese. Yum!

What potatoes are best to use in this recipe?

Starchy potatoes are best to use in this recipe and in any other mashed potato recipe. Russet potatoes or Yukon gold will be best.

These potatoes break down easily and provide a light and fluffy texture. Exactly what you want here!

A waxy potato, like red-skinned or fingerling, hold their shape and won’t provide the texture you want in mashed potatoes.

How to serve this recipe?

This recipe is a great side dish for any meal. Especially during the holiday season at Thanksgiving or Christmas dinner.

Serve with my crack greek beans, maple glazed carrots, and apple sausage stuffing for a well rounded holiday table.

Or alongside parmesan herb crusted salmon for a weeknight dinner.

How to best store this recipe?

Store this recipe in an airtight container in the refrigerator. It will keep for about 3-5 days!

Can I prepare this recipe ahead of time?

Yes, you definitely can!

This recipe is actually perfect to serve on a busy cooking day like Thanksgiving when both oven space and time is precious.

Just prepare the full recipe ahead of time. I recommend only 1-2 days ahead! Then store in the refrigerator and when it comes time to serve use the microwave to re-heat.

Add to a bowl, place a piece of paper towel over top, and heat in 1-2 minute intervals, mixing after each one. The dish should be fully heated through after about 5-6 minutes.

This method works perfectly and I even find the potatoes to be more delicious a day or two after.
