Creamy Mashed Potatoes With Green Onions: An Irish Classic

My grandmother, a woman whose culinary skills were as legendary as her stories, always made the most incredible mashed potatoes. But it wasn’t until years later, thumbing through an old Bon Appetit magazine, that I stumbled upon a recipe that tasted remarkably like hers. The secret? An abundance of green onions, stirred into the creamy potato base with melted butter for richness. It was a taste of childhood, a comforting hug on a plate, and a dish I still make to this day whenever I crave a little bit of home.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 40 minutes
• Total Time: 55 minutes
• Servings: 6
• Dietary Type: Vegetarian

Ingredients

• 2 lbs russet potatoes, peeled and quartered
• 1 cup milk
• 1 cup packed chopped green onion, bottoms and tops
• ½ cup unsalted butter, melted
• Salt and pepper to taste

Equipment Needed

• Large pot
• Medium saucepan
• Potato masher (or ricer)
• Large serving bowl
• Kitchen towel
• Lid

Instructions

1. Begin by preparing the potatoes. Place the peeled and quartered russet potatoes in a large pot. Cover with cold, salted water. Bring the water to a boil over high heat, then reduce the heat to medium and cook until the potatoes are tender when pierced with a fork – about 20-25 minutes.
2. Once the potatoes are cooked, drain them thoroughly in a colander. Return the drained potatoes to the empty pot.
3. Place the pot with the potatoes over low heat. This is a crucial step to evaporate any excess water that may be clinging to the potatoes, preventing them from becoming waterlogged. Cook for 2-3 minutes, stirring occasionally, until the potatoes appear drier.
4. Remove the pot from the heat. Place a clean kitchen towel across the top of the pot, and then cover the pot with a lid. This creates a steam bath that further dries the potatoes and ensures a fluffy texture. Let the potatoes stand, covered, for 10 minutes.
5. While the potatoes are steaming, prepare the milk and green onion mixture. In a medium saucepan, bring the milk to a simmer over medium heat. Be careful not to let it boil.
6. Add the packed chopped green onion (both the bottoms and the tops) to the simmering milk. Reduce the heat to low and simmer for 5 minutes, allowing the green onion to infuse its flavor into the milk.
7. While the green onions are simmering in the milk, lightly butter a large serving bowl. This will prevent the mashed potatoes from sticking and make serving easier.
8. After the potatoes have rested for 10 minutes, remove the lid and the kitchen towel. Mash the hot potatoes thoroughly in the pot using a potato masher or a ricer. If you prefer a smoother texture, use a ricer. Be careful not to over-mash, as this can make the potatoes gummy.
9. Pour half of the melted butter into the mashed potatoes.
10. Add the milk and green onion mixture to the mashed potatoes. Mix well until everything is thoroughly combined and the potatoes are creamy.
11. Season the mashed potatoes to taste with salt and pepper. Start with a small amount and add more as needed. Remember that the butter also contains salt, so taste as you go.
12. Spoon the mashed potatoes into the prepared serving bowl. Using the back of a spoon, create a well in the center of the potatoes.
13. Pour the remaining melted butter into the well in the center of the mashed potatoes. This creates a beautiful presentation and adds an extra burst of flavor.
14. Serve the mashed potatoes immediately while they are hot and creamy.

Expert Tips & Tricks

• For the fluffiest mashed potatoes, use a potato ricer instead of a masher. A ricer creates a much smoother and lighter texture.
• Don’t overwork the potatoes when mashing. Over-mashing releases too much starch, which can result in gummy potatoes.
• Warming the milk before adding it to the potatoes helps to keep the potatoes warm and prevents them from becoming gluey.
• If you don’t have fresh green onions, you can use 2-3 tablespoons of dried chives as a substitute. Add them to the milk mixture during the last minute of simmering.
• To make the mashed potatoes even richer, substitute heavy cream for the milk.
• Add a clove of minced garlic to the milk while simmering with the green onions for added flavor.
• For make-ahead preparation, you can prepare the mashed potatoes up to a day in advance. Store them in the refrigerator and reheat them gently over low heat, adding a little extra milk or butter if needed to restore their creamy texture.

Serving & Storage Suggestions

These mashed potatoes are best served hot and fresh. They make a wonderful side dish for roasted meats, poultry, fish, or vegetarian entrees. Garnish with a sprinkle of fresh green onion or a pat of butter for added visual appeal.

Leftover mashed potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm them in a saucepan over low heat, stirring frequently and adding a splash of milk or butter to restore their creamy texture. You can also reheat them in the microwave, but be careful not to overcook them. It is best to add a small pat of butter to help keep it from drying out in the microwave.

Freezing mashed potatoes is not recommended, as they can become grainy and watery when thawed.
