Making Roasted Garlic Mashed Potatoes is easy if you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare the Garlic: Slice the top off the head of garlic to expose the cloves. Drizzle with olive oil and wrap tightly in aluminum foil. Roast in the oven for 25-30 minutes until soft and fragrant.
3. Boil the Potatoes: While the garlic is roasting, peel and chop the russet potatoes into equal-sized chunks. Place them in a large pot, cover with water, and add a generous pinch of salt. Bring to a boil over medium heat.
4. Cook the Potatoes: Boil the potatoes until they are fork-tender, which should take around 15-20 minutes.
5. Drain and Dry: Once the potatoes are cooked, drain them thoroughly and return to the pot. This step ensures they don’t retain too much water.
6. Add the Roasted Garlic: Once the garlic is cool enough to handle, squeeze the softened cloves into the potatoes.
7. Incorporate Butter and Cream: Add the unsalted butter and heavy cream to the mixture. Mash with a potato masher or use an electric mixer for a creamier texture.
8. Season: Season with salt and pepper to taste. Mix until everything is well combined and smooth.
9. Garnish: Transfer the mashed potatoes to a serving bowl. Sprinkle with chopped chives for a fresh touch, if desired.

This straightforward process will guide you to create wonderfully flavorful Roasted Garlic Mashed Potatoes in no time.
