How to Make It

1. Prep the Garlic: Preheat your oven to 400°F (200°C). Slice off the top 1/4 inch of the garlic head, exposing the cloves. Place the garlic head on a small piece of aluminum foil, drizzle generously with olive oil, and sprinkle with a pinch of salt. Wrap the foil tightly around the garlic.
2. Roast the Garlic: Place the foil-wrapped garlic on a baking sheet. Roast for 35-45 minutes, or until the cloves are very soft and lightly browned. Remove from the oven and let cool slightly. Once cool enough to handle, squeeze the softened cloves out of their skins into a small bowl. Mash them with a fork until they form a paste.
3. Boil the Potatoes: While the garlic is roasting or cooling, place the peeled and chunked potatoes in a large pot. Cover them with cold water by about an inch. Add 1 teaspoon of kosher salt to the water. Bring the pot to a boil over high heat, then reduce the heat to medium-low and simmer for 15-20 minutes, or until the potatoes are fork-tender.
4. Infuse the Dairy: In a small saucepan, combine the whole milk and heavy cream. Add one of the rosemary sprigs to the mixture. Heat gently over low heat until warm, but do not boil. Let it steep for about 10-15 minutes to infuse the flavors. Remove the rosemary sprig before using.
5. Drain and Dry the Potatoes: Once the potatoes are tender, carefully drain them thoroughly in a colander. Return the empty pot to the stovetop over low heat for about 1 minute, shaking the pot gently. This helps to evaporate any residual moisture clinging to the pot, which can make for watery mashed potatoes.
6. Mash the Potatoes: Return the drained potatoes to the dry pot. Add the mashed roasted garlic paste, the warmed and infused milk/cream mixture, the unsalted butter, 1/2 teaspoon kosher salt, and 1/2 teaspoon black pepper.
7. Combine and Mash: Begin mashing the potatoes using a potato masher, a fork, or a ricer for the smoothest texture. Work gently to avoid overmixing, which can make them gummy. Stir until the butter has melted and the ingredients are well combined. If you prefer a smoother consistency, you can use a stand mixer with the paddle attachment on low speed for just a minute or two, being careful not to overwork them.
8. Taste and Adjust: Taste the mashed potatoes and adjust seasoning with more salt and pepper as needed. If the potatoes seem a little stiff, you can add another splash of warmed milk or cream.
9. Serve: Transfer the rosemary garlic mashed potatoes to a serving dish. Garnish with a few fresh rosemary leaves, if desired.

Bringing these simple steps together results in a batch of wonderfully fragrant and creamy rosemary garlic mashed potatoes that are a joy to eat.

Common Mistakes

• Using Waxy Potatoes: While all potatoes can be mashed, waxy varieties like red bliss or fingerlings can sometimes result in a less creamy, more lumpy texture compared to starchy potatoes like Russets or Yukon Golds, which are better suited for mashing to a smooth consistency.
• Not Draining Potatoes Thoroughly: Excess water clinging to the potatoes after boiling can lead to watery mashed potatoes, diluting the flavor and affecting the texture. Ensure they are drained well and the pot is dry.
• Overworking the Potatoes: Mashing or mixing potatoes too vigorously can break down their starches improperly, leading to a gummy or gluey texture. Gentle mashing is key.
• Not Warming Dairy:** Adding cold milk or cream to hot potatoes can shock them and prevent the ingredients from combining smoothly. Warming the dairy helps create a more cohesive and creamy mash.
• Skipping the Garlic Roasting: While you can use raw garlic, roasting it mellows the flavor, removing any harshness and bringing out a delightful sweetness that integrates much more harmoniously into the mashed potatoes.
• Not Tasting and Adjusting Seasoning:** Potatoes can absorb a lot of salt. It’s crucial to taste and adjust the seasoning at the end to ensure the flavors are well-balanced and the potatoes are seasoned to your preference.

Avoiding these common pitfalls will help ensure your rosemary garlic mashed potatoes turn out creamy, flavorful, and delightful every time.

Storage and Reheating

• Storage: Once cooled to room temperature, transfer leftover rosemary garlic mashed potatoes to an airtight container. Store in the refrigerator for up to 3-4 days.
• Reheating in the Oven: For best results, transfer the mashed potatoes to an oven-safe dish. Add a splash of milk, cream, or broth (about 1-2 tablespoons per cup of mashed potatoes) to help them regain moisture. Cover with foil and bake at 350°F (175°C) for 20-30 minutes, or until heated through. Remove foil for the last 5-10 minutes if you’d like a slightly crisped top.
• Reheating on the Stovetop: Gently heat the mashed potatoes in a saucepan over low heat. Add a splash of milk, cream, or butter to help loosen them up. Stir frequently to prevent sticking and ensure even heating.
• Reheating in the Microwave: Place the mashed potatoes in a microwave-safe dish. Add a splash of milk or cream and cover loosely. Heat on medium power in 30-second intervals, stirring in between, until heated through. Be mindful not to overheat, which can dry them out.

Proper storage and careful reheating are essential to enjoying your rosemary garlic mashed potatoes even after the initial meal. These methods help preserve their creamy texture and rich flavor, ensuring your leftovers are just as enjoyable as when they were freshly made.

Leftover Ideas

• Shepherd’s Pie Topping: Use leftover mashed potatoes as the topping for a classic Shepherd’s Pie, layering them over a mixture of ground meat and vegetables.
• Potato Cakes or Patties: Mix the mashed potatoes with a beaten egg, a little flour, and finely chopped leftover herbs or cheese. Form into patties and pan-fry until golden brown and crispy.
• Stuffed Mushrooms: Combine mashed potatoes with breadcrumbs, herbs, and a binder like cheese, then use this mixture to stuff large mushroom caps and bake.
• Base for Fancy Toast: Spread a generous dollop of seasoned mashed potatoes on toasted rustic bread, then top with sautéed mushrooms, crumbled bacon, or a poached egg for a satisfying brunch or light meal.
• Enriching Soups: Stir a spoonful of mashed potatoes into cream-based soups or vegetable purées to add body and a subtle, comforting flavor.
