Potatoes are a great starch option to complete any meal!

As an environmental scientist, I am always trying to make sustainable ingredients shine. Potatoes, especially when sourced organically, are a sustainable crop.

They have a relatively small environmental footprint as they only require a small area to thrive and have a super long shelf life, which means you’re less likely to waste them!

And the best part? Potatoes can generally be sourced locally year-round.

Boursin Mashed Potatoes Ingredients

Here’s everything you need:

  • Russett Potatoes. Or Yukon gold. Both are great for mashing! I stick to Russett because that’s how my mom makes them, and they just taste like home to me.
  • Milk. Any unsweetened milk will do, dairy or not!
  • Unsalted butter. Using unsalted butter gives you more control over the salt content of your potatoes. That being said, if you only have salted butter at home, that works, too. Just make sure you adjust the amount of garlic salt you add so your creamy mashed potatoes aren’t overly salty.
  • Garlic Salt. I love this ingredient because it adds the extra flavor of garlic and salt simultaneously. Of course, if you aren’t a fan of garlic, just use salt. If you don’t have garlic salt at home, you can also use a combination of salt and garlic powder.
  • Boursin. Any flavor will do! I used the garlic and fine herbs flavor in the dish pictured, but I’ve also made this with the basil & chive and shallot & chive flavors with great success.

Boursin Mashed Potatoes Tips and Tricks

Peel Your Potatoes

To get super creamy mashed potatoes, peel the potatoes completely using a vegetable peeler, leaving behind no skin or bruises. I use this same technique for these Truffle Parmesan Fries!

If you don’t have a compost bin for your peels, these Potato Peel Crisps are a delicious way to avoid food waste!

Green tip: Did you know that of the billions of pounds of food wasted annually, it is estimated that 50% of it happens in our homes? It’s always best to avoid food waste as much as you can!

If you like some potato peel chunks in your mashed potatoes, just leave a couple of strips of peel on during this process. The rest of the steps for this recipe will be the same.

Chop Your Potatoes into Chunks

Breaking the potato into smaller parts helps the potatoes cook faster!

Once peeled, chop your potato into small pieces, roughly about 2 square inches. While the chunks do not need to be perfectly uniform by any means, make sure they are closely similar in size.

This will just ensure that they cook evenly, keeping the consistency of your potatoes creamy throughout.

Boil The Potato Chunks

Bring a pot of about 10 cups of water to a boil and carefully drop your potato chunks in.

Green tip: Don’t waste the water your potatoes boil in—use it to water your plants! The starchy water helps fertilize plants and help them grow.

Boil for about 20 minutes, until you can easily pierce the potatoes with a fork.

Consider a Potato Masher

Investing in a potato masher has been a game-changer for my mashed potatoes! It helps to get out all the lumps and crush the potatoes down into little, whippable pieces.

Once you’ve drained your water, add the potato chunks to a large mixing bowl and mash. If you don’t have a potato masher, you can use a muddler or a fork to mash them.

Add All Your Ingredients

Time to add your milk, butter, garlic salt, and Boursin!

Start with just 1/4 cup milk. Mix and asses the consistency. Depending on the size of your potatoes, you may need a little more.

If you feel your potatoes are too thick, add more milk, about 1 tablespoon at a time, whipping in between until you reach your desired consistency. You shouldn’t need more than a maximum of 1/2 cup.

Use a Hand Mixer

The best way to get creamy mashed potatoes is to whip them. I find the easiest way to whip them is with a hand mixer on high.

Should You Have Leftovers

In an airtight container, these mashed potatoes will stay fresh for up to 5 days in the refrigerator. You can also freeze them for up to a year!

To reheat, preheat your oven to 350°F and transfer the mashed potatoes into an oven-safe dish. Cover the dish with tin foil, and cook for about 20 minutes until heated through.

If your mashed potatoes are frozen, allow them to thaw overnight before following the reheating guidelines above.
