• Parmesan And Garlic For Real Depth: Instead of tasting flat, these homemade mashed potatoes are layered with savoury flavour from garlic and parmesan, so every bite feels complete.
• Hot Milk For A Fluffier Finish: When making mashed potatoes, adding hot milk keeps the mash soft and silky rather than cooling it down and making it stiff.

• Reliable, Crowd Pleasing Texture: This method gives you consistently smooth, fluffy mashed potatoes whether it is a simple weeknight dinner or a special occasion.

What You Need For Mashed Potatoes

This mashed potatoes recipe keeps things simple while focusing on what truly makes homemade mashed potatoes creamy, fluffy and full of flavour.

• Potatoes: Russet, Yukon Gold, Dutch Cream, Creme Gold or Creme Royale all work beautifully. Starchy varieties give you that light, fluffy texture, while creamier ones add natural richness when making mashed potatoes.
• Unsalted Butter: Softened butter blends smoothly into the hot potatoes and creates that velvety finish without overpowering the flavour.
• Hot Milk: Adding milk while it is hot keeps the mash silky and smooth. Cold milk can cool the potatoes too quickly and affect the final texture.
• Sour Cream: This is what sets this mashed potatoes recipe apart. It adds extra creaminess and a subtle tang that makes these homemade mashed potatoes taste fuller and more balanced.

Add Ins And Substitutions

This mashed potatoes recipe is creamy and flavour packed as is, but you can easily adjust it depending on what you have on hand or what you are serving it with.

• Swap The Dairy: Use full cream milk for extra richness or lighten things up with reduced fat milk. You can also replace part of the milk with pouring cream for ultra indulgent homemade mashed potatoes.
• Make It Extra Garlicky: Roast the garlic instead of sautéing it for a sweeter, deeper flavour when making mashed potatoes.
• Skip The Parmesan: If you prefer a more classic flavour, leave it out. The sour cream and butter will still give you beautifully creamy mashed potatoes.
• Add Fresh Herbs: Stir through chopped chives, thyme or parsley for a fresh lift that works especially well with roast meats.
• Make It Lighter: Replace some of the butter with extra sour cream for a slightly lighter finish without losing that creamy texture.

On the stove

1. Prep Potatoes: Peel and cut potatoes into quarters, removing any spots. Keeping the pieces similar in size ensures they cook evenly and gives you smoother mashed potatoes later on.

1. Boil Until Tender: Place the potatoes into a large pot and cover with cold salted water by about an inch. Bring to a boil, then reduce to medium low and simmer for 15 to 20 minutes until fork tender.

1. Sauté The Garlic: Just before the potatoes finish cooking, melt 1 tablespoon of butter in a small pan over medium heat. Cook the garlic for about 1 minute until fragrant, then remove from the heat and keep warm.

1. Drain And Combine: Drain the potatoes thoroughly and return them to the hot pot. Add the remaining butter, sautéed garlic, hot milk and sour cream while everything is still warm for the creamiest texture.

1. Mash: Mash the potatoes gently until creamy and mostly smooth, adding a splash more hot milk if needed. For extra smooth homemade mashed potatoes, use a wooden spoon or electric beaters without overmixing.

1. Finish And Season: Stir through the parmesan cheese until melted and combined. Season with salt and pepper to taste, then serve immediately while your mashed potatoes are hot, fluffy and ready to enjoy.

Pro Tips For The Creamiest Mashed Potatoes

• Start With Cold Water: Always place your potatoes into cold salted water before bringing to a boil. This helps them cook evenly from the inside out when making mashed potatoes.
• Salt The Water Properly: The water should taste lightly seasoned. This is your first chance to build flavour into the potatoes, not just at the end.
• Drain Thoroughly: After boiling, let the potatoes sit in the colander for a minute so excess steam escapes. Too much moisture can make mashed potatoes watery.
• Warm Your Milk: Adding hot milk keeps the mash silky and smooth. Cold milk can cool the potatoes too quickly and affect the texture.
• Mash While Hot: Mash the potatoes as soon as they are drained and still steaming. This helps create fluffier homemade mashed potatoes.
• Do Not Overmix: Once the dairy is added, mix gently. Overworking the potatoes releases too much starch and can turn your mashed potatoes gluey.

Recipe FAQ's

Gluey mashed potatoes usually happen from overmixing. When making mashed potatoes, too much beating releases excess starch. Mash gently and stop as soon as they are smooth and combined.

You can, but texture may change slightly. For best results, freeze well cooled mashed potatoes in portions and reheat slowly with extra milk or butter to bring them back to life.

Starchy potatoes like Russet create fluffier mashed potatoes, while Yukon Gold or Dutch Cream give a naturally creamier finish. Both work beautifully in this mashed potatoes recipe depending on your preference.

What you need

• 2 pounds potatoes Russet, Yukon Gold, Dutch Creams, Creme Gold, Creme Royale
• 1 teaspoon salt
• 1/2 cup milk hot

Method

1. Peel and cut potatoes into quarters lengthwise. Remove any spots, lumps or knots.
2. Place potatoes in a large pot (6-quart) and cover with cold, salted water by an inch. Bring to a boil, reduce heat down to medium-low and allow to simmer until fork tender (about 15-20 minutes).
3. When potatoes are just about done (nearly fork-tender), heat 1 tablespoon of the butter in a small pan over medium-high heat. Sauté garlic until fragrant, about 1 minute. Set aside and keep warm.
4. Drain cooked potatoes, add in the remaining butter, cooked garlic, hot milk and sour cream.
5. Mash the potatoes with a potato masher until smooth, adding a little extra milk if needed. (OPTIONAL: Use a strong wooden spoon OR electric beaters to beat further until smooth. Be careful NOT to over beat or they will become gluey.)
6. Add in the parmesan cheese. Season with salt and pepper to taste.
