Boursin Cheese Mashed Potatoes

I know it was only last week I uploaded my Boursin Pasta, but I just couldn’t resist this 🤪 It was actually a follower on Instagram that suggested trying Boursin with mashed potatoes (thank you Joanne!) and my life changed on the spot. There’s no way I couldn’t!

Anywho, as you can imagine this recipe is fairly simple. But there are a few tips and tricks I suggest giving a go in order to take these potatoes to the next level.

Chicken Stock

The first thing I suggest doing right off the bat is boiling your potatoes in chicken stock. This will add a nice gentle background flavour to the spuds. The chicken flavour compliments the garlic and herbs in the Boursin insanely well. If you don’t have stock, water works just fine.

Process shots: add potatoes to pot (photo 1), pour in stock (photo 2), boil until knife tender (photo 3).

Making Boursin Mashed Potatoes

Once you’ve boiled the spuds just let them steam dry for a few mins, just so they don’t go sloppy when you mash them. The more they steam = the most moisture escapes = the less watery the mashed potatoes will be.

What can I add to Boursin Mashed Potatoes?

Alongside the potatoes and Boursin, I like butter and whole milk. You can add cream or half and half, but just go steady as the cheese already makes the potatoes quite rich.

Can I make these ahead of time?

These are best made fresh, but you can store in the fridge and reheat. I recommend bringing them to room temp then blitzing them in the microwave. Bringing them to room temp will help them reheat more evenly.

Process shots: drain potatoes (photo 1), add butter and Boursin and mash until smooth (photo 2), stir in seasoning and milk/cream (photo 3).

Serving Boursin Mashed Potatoes

To serve I usually drizzle over an extra tbsp of melted butter, but this is totally optional 😋 These go great as part of a roast dinner, with a steak or even with sausages and gravy!

Quick 1 min demo!


a) Chicken Stock - I love boiling the potatoes in chicken stock, just for an extra hit of flavour. Chicken goes with both garlic and herbs beautifully, so works really well here. Not a deal breaker if you just use water. They'll still be delicious.
b) Milk or Cream - I tend to use milk, just because the cheese already makes the mash quite rich. In both cases though I recommend using the liquid at least at room temp. Warmer milk/cream will infuse into the potatoes easier.
c) Make Ahead - Leave off the final drizzle of butter and cover in the fridge. I usually bring to room temp before I microwave so it warms through more evenly. You can also add a splash of cream/milk and stir over medium heat in a suitably sized pot.
d) Calories - Assuming 1/3 cup whole milk is used and 1 tsp salt in total is in the dish. Divided by 5.
