First, pour the 6 cups of chicken broth into a large pot and bring it to a rolling boil over high heat. While the broth is heating up, take your russet potatoes, peel them completely, and give them a good rinse under cool water. Then, carefully cut them into uniform, bite-sized pieces to ensure they cook evenly.
Carefully add the potato pieces to the boiling chicken broth. If the broth doesn’t completely cover the potatoes, you can add just enough water to submerge them. Once the broth returns to a boil, reduce the heat to a medium-low simmer. Let them cook for about 10-15 minutes, or until they are fork-tender and easily pierced.
Drain the cooked potatoes and return them to the warm pot. Add the butter, cream cheese, salt, and white pepper. Using a potato masher for a rustic texture or a hand mixer on low for a creamier result, mash everything together until it’s smooth and all the ingredients are fully combined.
Finally, stir in the 2 cups of shredded smoked gouda cheese. Continue to mix until the cheese is completely melted and beautifully integrated throughout the mashed potatoes. The residual heat from the potatoes will melt the gouda perfectly, creating a smooth, cheesy finish. Serve immediately while hot.
