1. Roast the Garlic

• Preheat your oven to 200°C (400°F).
• Slice the tops off the garlic bulbs to expose the cloves slightly.
• Drizzle with olive oil and wrap each bulb in foil.
• Roast for 35–40 minutes until the cloves are golden, soft, and fragrant.
• Let cool, then squeeze the roasted cloves out of the skins into a small bowl and mash gently.

2. Cook the Potatoes

• Place chopped potatoes in a large pot and cover with cold water.
• Add a generous pinch of salt to the water.
• Bring to a boil over medium-high heat and cook for 15–20 minutes until fork-tender.
• Drain the potatoes and return them to the pot to release excess steam.

3. Mash the Potatoes

• While potatoes are still hot, mash using a potato masher, ricer, or hand mixer.
• Add the softened butter, warm milk, sour cream (if using), and mashed roasted garlic.
• Continue mashing or stirring until smooth and creamy.
• Season with salt and black pepper to taste.

4. Serve and Garnish

• Transfer mashed potatoes to a serving bowl or platter.
• Garnish with chopped chives or parsley, if desired.
• Serve hot with your favorite main course.
