Place potatoes into large saucepan and add enough water to cover by about an inch. Cook over medium-low heat until fork tender, about 15-20 minutes.

Drain potatoes in a colander and then put the potatoes back into the pot they were cooked in. Mash potatoes over low heat until smooth.

In a microwave safe measuring cup, combine butter and half and half. Warm until butter has melted. Add the butter mixture, sour cream, and boursin cheese to potatoes.

Continue to mash the potatoes until everything is thoroughly combined and all large chunks are broken up. Stir in salt and pepper and mix until combined.

Put potatoes into a serving bowl for serving; cover with aluminum foil to keep warm. If necessary, warm in 350º F oven for about 20 minutes before serving.

When ready to serve, sprinkle with salt, pepper and paprika. Dot with a couple of tablespoons of additional butter if desired.

Serve warm.
