Boil the garlic and potatoes: Add the potatoes and garlic cloves to a large pot. Cover them with filtered water until the water line is one inch above. Bring to a boil and cook for 15-20 minutes or until the potatoes are fork-tender.
Add remaining ingredients: Drain the water from the potato and garlic mixture. Add in the butter, black pepper, onion powder, sour cream, and milk.
Mash the potatoes: Using a potato masher or an electric mixer, mash the potatoes until the milk and butter are thoroughly mixed and the potatoes reach a creamy consistency with a few lumps. Serve while hot. Enjoy!

Recipe Tips
- Choosing petite red potatoes is crucial as they have a naturally creamy texture and sweet flavor, making for a smoother mash.
- Make sure to start with cold water when boiling your potatoes and garlic; this ensures they cook evenly and thoroughly.
- Don't peel your red potatoes; the skins are not only nutritious but also contribute to the rustic texture and appearance while adding fiber.
- To check if your potatoes are cooked, insert a fork into one piece; if it enters smoothly with no resistance, they're ready for mashing.
- Instead of just adding the butter straight from the fridge, let it reach room temperature; it'll mix more efficiently into the hot potatoes, creating a creamier consistency.
- Be cautious with the amount of liquid you add; it's best to add milk gradually to avoid overly liquid potatoes.
- Use a potato masher for a rustic, chunkier texture, but if you prefer smoother potatoes, use an electric mixer. Be careful not to over-mix, or your potatoes might become gummy.
- If you're not serving them immediately, keep the mashed potatoes warm by placing them in a heatproof bowl and setting them over a pot of simmering water; they’ll stay warm and creamy until you're ready to serve.
Variations
- Incorporate cheese for a cheesy twist; stirring in grated Parmesan, cheddar, or Gouda cheese after mashing.
- Replace the sour cream with plain Greek yogurt for a lighter version that maintains a creamy consistency but with more protein and less fat.
- Add some greens by mixing in cooked, finely chopped spinach or kale with the mashed potatoes, boosting the nutritional value.
- Add a bit of heat with a teaspoon of cayenne pepper or a couple of dashes of your favorite hot sauce, enhancing the warmth and complexity.
- Fresh herbs like chives, parsley, or rosemary can be finely chopped and stirred in after mashing for a fragrant, garden-fresh taste and a pop of color.
- If red potatoes aren’t available, feel free to use another type, such as Yukon Gold for a buttery flavor or Russet potatoes for a fluffier texture; just keep in mind the consistency might slightly change.

Storing & Freezing
Storing: To store leftover garlic mashed potatoes, place them in an airtight container and refrigerate for 3-5 days. Do not leave the mashed potatoes at room temperature for more than two hours, as bacteria grow rapidly at temperatures between 40 °F and 140 °F. When you're ready to reheat, add a little more milk or butter to restore the original creamy consistency, as they tend to thicken when chilled.
Freezing: To freeze, spoon your cooled mashed potatoes into individual portion sizes on a baking sheet or place them directly into freezer-safe bags or containers. Before sealing, press out as much air as possible to prevent freezer burn. They can be stored in the freezer for up to 6 months. When you're ready to enjoy, thaw them overnight in the refrigerator, then reheat them in the microwave or on the stovetop, stirring occasionally and adding additional milk or butter as needed to reach your desired consistency.
FAQ
If fresh garlic isn't available, you can substitute with ½ teaspoon of garlic powder for every clove of garlic called for in the recipe. However, keep in mind that the distinctive depth of flavor achieved with fresh garlic will be slightly different, and the dish may have a milder garlic taste.
If your mashed potatoes are too runny, you can thicken them by returning them to the heat and cooking on low, allowing excess moisture to evaporate. Be sure to stir frequently to prevent sticking, and you can also add more mashed potato flakes or cooked mashed potatoes to help absorb some of the excess liquid.
