How to Make Rosemary Garlic Mashed Potatoes

2. Boil the potatoes – Place potato chunks in a pot, cover with cold water, add 1 tsp salt, and bring to a boil. Cook 15–20 minutes until fork-tender.
3. Mash – Drain well, return potatoes to the pot, and mash with roasted garlic cloves.
4. Mix – Stir in butter, cream, and rosemary. Adjust with more cream if you like a smoother consistency.
5. Season – Add salt and pepper to taste, then serve warm.

That’s it—simple steps for fluffy, flavorful mashed potatoes that everyone will love.

You Must Know

• Potato choice matters – Yukon Golds give a creamy, buttery texture, while Russets are lighter and fluffier.
• Don’t overwork – Over-mixing releases starch and makes potatoes gluey. Mash gently.
• Warm your dairy – Always add warm cream and butter so the potatoes absorb them easily.
• Drain well – Extra water dilutes flavor and makes potatoes runny. Let them steam dry before mashing.
• Balance flavors – Fresh rosemary is strong—start small, then adjust.

These small details are what separate ordinary mash from unforgettable mashed potatoes.

Perfecting the Cooking Process

• Salt the water generously – Like pasta, potatoes absorb flavor as they cook.
• Roast the garlic fully – Soft, golden cloves give sweetness without bitterness.
• Infuse cream with rosemary – For deeper flavor, warm the cream with rosemary before adding.
• Texture control – For silky potatoes, use a ricer; for rustic style, mash by hand.
• Finish with a swirl of butter – Adds richness and makes the top look glossy and inviting.

With these steps, you’ll achieve smooth, flavorful potatoes every single time.
