If you want to take your mashed potatoes to a new level, then these Instant Pot Boursin Mashed Potatoes are exactly what you need. The Boursin cheese adds a rich, herby twist, transforming this classic side from good to outstanding!

Whether you’re prepping for a holiday feast or just want to treat your family to something special, these Boursin Mashed Potatoes are sure to become a new favorite.

This recipe was inspired by a Mom’s Dinner mashed potatoes recipe I found years ago. I’ve been tweaking it over the years to create the perfect version for my family. After discovering the delicious herb flavor of Boursin cheese (which I’m completely obsessed with), I knew it would be the ideal addition to my instant pot mashed potatoes.

This recipe is a must-have for Thanksgiving, Christmas, or any special occasion. I also love pairing these creamy mashed potatoes with main dish recipes like Hamburger Green Bean Casserole, Mini Meatloaves, BBQ Meatloaf, and Swedish Meatballs—each one elevated by the rich, comforting flavor of these potatoes.

When I make potatoes on a busy weeknight, it instantly feels like a family Sunday dinner. The addition of these creamy mashed potatoes elevates an ordinary weeknight meal to something truly special.

Simple ingredients needed for homemade Boursin mashed potatoes

• Russet Potatoes – They are my favorite potato for making mashed potatoes. Yukon gold potatoes would be my second choice.
• Boursin Cheese – This soft cheese with garlic and herbs is so good. Cream cheese is a good substitute. I find the best deal on Boursin cheese at Cosco.
• Butter – You can’t beat buttery flavor in potatoes. Use either salted or unsalted butter.
• Kosher Salt – Use 1 1/2 teaspoons of table salt if you do not have kosher on hand.
• Milk – Half and half or heavy cream can be substituted.
• Sour Cream – Use your favorite brand.

Stovetop directions are included in the recipe card below.

Step 1: Start by peeling the russet potatoes and cutting them into quarters.

Step 2: Place the potato chunks into the Instant Pot. Add 1/2 cup of water and sprinkle 2 teaspoons of kosher salt over the potatoes.

Step 3: Secure the lid on the Instant Pot, ensuring the valve is set to the sealing position. Select the manual setting and set the timer for 11 minutes on high pressure.

Step 4: Once the cooking time is up, carefully perform a quick release by turning the valve to the venting position. When the pressure has fully released, open the lid. It is not necessary to drain the potatoes.

How to make ultra-creamy Boursin mashed potatoes – stovetop cooking instructions

Prepare the Potatoes: Start by peeling the russet potatoes and cutting them evenly-sized chunks. This will help them cook evenly and more quickly.

Boil the Potatoes: Place the potato chunks in a large pot and cover them with cold water, ensuring the water level is about 1 inch above the potatoes. Add salt and bring the potatoes to a boil over high heat. Once boiling, reduce the heat to medium and simmer the potatoes for 15-20 minutes or until they are fork-tender.

Drain the Potatoes: Once the cooked potatoes are tender, carefully drain them in a colander. Allow them to sit for a minute or two to let any excess water evaporate.

Mash the Potatoes: Return the drained potatoes to the pot or transfer them to a large mixing bowl. Add the butter, milk, sour cream, and Boursin cheese to the hot potatoes. Using a potato masher, an electric mixer, mash the potatoes until you reach your desired consistency.

Adjust Seasoning and Serve: Taste the mashed potatoes and add more salt if needed. You can also adjust the consistency by adding more milk if the potatoes are too thick. Serve the mashed potatoes immediately, garnished with fresh herbs or an extra pat of butter if desired.

Tips for achieving creamy Boursin mashed potatoes

• Russet potatoes are ideal for this recipe because they are high in starch, which results in fluffy and smooth mashed potatoes. Be sure to peel them thoroughly for the best texture..
• Don’t cut the potatoes smaller than in quarters.
• Don’t skip the salt! Adding salt to the cooking water enhances the flavor of the potatoes right from the start.
• For smoother mashed potatoes, make sure the butter, Boursin cheese, milk, and sour cream are at room temperature before adding them to the hot potatoes. This will help them blend more easily and create a creamier texture.
• If your mashed potatoes seem too thick, you can thin them with more milk. Add it gradually until you reach the desired consistency.
• Garnish your mashed potatoes with fresh herbs like chives or parsley, or add an extra pat of butter on top for a little extra richness and presentation.

Easy variations of Boursin mashed potatoes
