Ingredients for Ultra Creamy Garlic Mashed Potatoes
Getting the creaminess right starts here, with really good ingredients. You don’t need too many fussy things, but quality matters, especially with the dairy! I always measure everything out first—it makes the mixing process so much smoother when the potatoes are piping hot.
For the Potatoes
- 3 pounds red potatoes. If you’re feeling brave, don’t peel them! The skins are soft and add character, which I just love for this mashed potatoes recipe.
For the Creamy Garlic Flavorings
- 4 tablespoons butter (get the good stuff, seriously!)
- 8 ounces sour cream
- 1/2 cup whole milk (make sure it’s room temperature if you can!)
- 1 tablespoon minced garlic
- 1 teaspoon garlic powder. Don’t be shy; you can totally go up to 2 teaspoons if you want that big garlic punch.
- 1 teaspoon salt (again, taste test and add up to 2 teaspoons if needed)
- 1/4 teaspoon cracked black pepper
Essential Equipment for Ultra Creamy Garlic Mashed Potatoes
Listen, you don’t need a kitchen full of fancy gadgets for amazing comfort food favorites like these garlic butter potatoes. But a couple of things really make the process go from a chore to a joy. It’s all about setting yourself up for success before those potatoes even hit the water!
First up, you absolutely need a large pot. We’re cooking three pounds of potatoes here, and they need room to boil happily without making a huge starchy mess all over your stovetop. Trust me, I learned that lesson the hard way!
Next, you have two choices for mashing, and this choice really determines that “ultra creamy” texture we are aiming for. You can certainly use a classic potato masher. If you use a masher, just be gentle! We want fluffy, not gluey.
But, if you’re like me sometimes and want that guaranteed smooth texture without breaking a sweat, grab your hand mixer. It whips everything up beautifully, but the key here is a light touch—just pulse it a few times until it’s barely combined. You don’t want to overdo it, or you’ll activate the starch too much. Oops!
Lastly, if you’re short on time and really want to make this the fastest mashed potatoes recipe ever, having an Instant Pot on hand is a total game-changer. It cooks them perfectly under pressure, meaning less time hovering over a boiling pot. Total time saver for those big holiday meals!
Step-by-Step Instructions for Ultra Creamy Garlic Mashed Potatoes
Alright, time to get cooking! This is where the magic happens to transform those humble red potatoes into glorious, decadent Ultra Creamy Garlic Mashed Potatoes. Honestly, whether you use the stovetop or your trusty Instant Pot, the key is making sure your potatoes are fork-tender before you start adding all that delicious dairy.
The first step after cooking is quick: get those hot, drained potatoes into a big bowl. Don’t let them sit around and cool off! We are going right in with the 4 tablespoons of butter, the sour cream, the whole milk, and every bit of that garlic flavor we prepped. Mix it gently until it’s just combined.
Cooking the Potatoes: Stovetop or Pressure Cooker
You’ve got options here, so pick the one that works best for your schedule! If we are doing the classic stovetop method, I cut my potatoes into quarters—this helps them cook evenly. Cover them with water by about an inch, bring it to a rolling boil over high heat, and then knock it down to a steady boil for maybe 10 to 12 minutes. They’re done when a fork slides right through without a fight.
If you’re using that fantastic Instant Pot I mentioned, pop the rack in with a cup of water underneath. Set the pressure for 8 minutes on high. When it’s done, quick-release that pressure right away, drain them well, and get them into your mixing bowl fast. This lets them absorb all that glorious fat!
Creating the Ultra Creamy Garlic Mashed Potatoes Base
Once everything is tumbling together in that big bowl—hot potatoes, butter melting, sour cream swirling—you have to be mindful! This is crucial if you want that incredible texture found in my favorite comfort food favorites recipes.
If you’re using the masher, work quickly and only mash until most of the clumps are gone. If you use a hand mixer, I swear on my favorite spatula, use the lowest speed and only pulse it 3 or 4 times! Over-mixing potatoes, no matter what kind you use, turns them gummy and sludgy, and we want rich and fluffy, not wallpaper paste!
Once they look *just* combined, taste them! Right now, you add any extra salt, pepper, or garlic powder you need. Remember, the potatoes are hot, so the flavor isn’t fully developed yet. Serve these beautiful garlic butter potatoes right away!
Tips for Perfect Ultra Creamy Garlic Mashed Potatoes
You know, making mashed potatoes seems easy—it’s just boil, mash, done, right? Wrong! If you want that “ultra creamy” experience, the little things make all the difference. I learned these tricks the hard way after too many batches ended up tasting exactly like spackle.
First tip, and listen close: temperature is your friend. If you dump ice-cold milk and butter into steaming hot potatoes, the butter seizes up, and the starches don’t blend well. Before I even start boiling the potatoes, I set the 4 tablespoons of butter and the 1/2 cup of milk out on the counter. Letting them come closer to room temperature helps everything emulsify beautifully. That way, when you add them in, they melt right into the potatoes instead of sitting there in cold clumps.
Next, let’s talk about the potato choice itself. I insist on using red potatoes, partly because they hold their shape nicely and give a slightly sturdy texture, which I love mixed with the creaminess. If you decide to peel them (and you absolutely don’t have to!), make sure you boil them until they are completely tender. Seriously, fork-tender, falling apart tender! Any hard bits left mean you’ll be over-mashing later trying to break them down, and that’s how you get gluey mashed potatoes.
And that leads straight to the non-gluey heaven secret: stop mashing! Once you add the sour cream and the liquids, you only want to work the mixture just until everything is incorporated. You should still see tiny peaks or small soft lumps if you look closely. That slightly rustic texture is authentic, it’s delicious, and it keeps you from activating too much starch. It takes real restraint, I know, but trust me, your ultra creamy garlic mashed potatoes will thank you for taking it easy with the masher!

Storage and Reheating Your Ultra Creamy Garlic Mashed Potatoes
Nobody wants dinner leftovers sitting around forever, but knowing how to store and perfectly reheat these garlic butter potatoes ensures you get that ultra creamy satisfaction again later! If you happen to have any leftover—which I doubt, because they are addiction-level good—storing them correctly is key to avoiding a dry, sad reheated batch.
When it comes to storage, transfer your Ultra Creamy Garlic Mashed Potatoes to an airtight container as soon as they cool down slightly. Don’t leave them out on the counter for more than two hours, okay? Food safety first, always! Kept sealed up tight in the fridge, they’ll maintain their amazing texture for about three to four days. They really are best on day one, but these hold up really well!
Reheating on the Stovetop (Best Method!)
If you want to bring these comfort food favorites back to life with the least fuss and the best texture, the stovetop is your spot. This method lets you control the moisture perfectly. Scoop the leftovers into a saucepan over low heat. Now, here’s the secret sauce: add a little splash of warm milk or a tiny pat of butter right into the pan.
Stir gently—remember that anti-gummy rule!—until everything is heated through and creamy again. If they seem a little stiff, that splash of warmed liquid will loosen them up right away. This keeps the flavor bright and the texture velvety smooth.
Quick Reheating in the Microwave
If you’re just nuking a single serving right before dipping into it, the microwave works fine, but you have to be cautious. Put your portion into a microwave-safe bowl. Cover it loosely with a damp paper towel. This helps trap steam so the potatoes don’t dry out around the edges while the middle warms up.
Heat in 30-second bursts, stirring well between each one. You’ll likely need to stir in just a tiny drop of milk or water halfway through heating if they seem tight. Just keep checking them until they hit that perfect, warm, creamy temperature. Enjoy those leftovers!
Frequently Asked Questions About Garlic Butter Potatoes
I get asked so many questions about these garlic butter potatoes, especially since we’re aiming for that perfect texture while keeping the carbs low! It makes total sense, as mashed potatoes can be tricky. Here are a few of the things I hear most often when people are trying to make my famous garlic butter magic happen.
Can I substitute the sour cream for a keto-friendly option?
That’s a great question, especially for my fellow low-carb cooks! Butter and sour cream are amazing sources of rich fat, which is why they work so well here. If you need to cut the carbs even further or swap out the sour cream, you can absolutely use full-fat cream cheese. Just make sure it’s softened up really well! You might need to add a tiny bit more milk or heavy cream to get the mixture moving smoothly, but the richness factor stays high.
How do I prevent my Ultra Creamy Garlic Mashed Potatoes from becoming watery?
Watery potatoes are the absolute worst! It happens when you don’t drain the cooking water completely—or worse, when the potatoes absorb too much extra water inside after they’ve been cooked. The secret to keeping these Ultra Creamy Garlic Mashed Potatoes rich and not runny is draining them so thoroughly!
After you boil or pressure cook them until tender, drain them in a colander, but don’t stop there! Let them sit in the colander for a solid 5 minutes right over the sink before transferring them to your mixing bowl. That resting time lets all that surface water evaporate off. If you skip that step, the residual water ends up thinning out your butter and sour cream mix, and boom—watery mash.
What is the best way to reheat these garlic butter potatoes?
This is key for enjoying those leftovers! You want to warm them up gently so they don’t seize up or dry out. You have two main options, but I always lean towards the stovetop because it gives you better control over moisture.
For the stovetop, throw the leftovers in a non-stick saucepan over very low heat. Seriously, low and slow. Add just a small splash of warmed heavy cream or milk—just enough to loosen them up. Stir gently until they are heated evenly. If you’re in a rush, the microwave works, but remember to cover them with a damp paper towel and heat in short bursts, stirring in between to stop the edges from turning tough.

Ultra Creamy Garlic Mashed Potatoes
Ingredients
Equipment
Method
- Cook the potatoes using the stovetop or Instant Pot method described below.
- In a large bowl, combine the hot, drained potatoes, butter, milk, sour cream, garlic, garlic powder, salt, and pepper.
- Use a potato masher or a hand mixer to mix the ingredients just until they are combined. The potatoes should still have a few lumps; do not over-mix.
- Taste the potatoes and add more salt and pepper if needed. Serve immediately.
- Stovetop Method: Cut the potatoes into quarters. Place them in a large pot and cover with water so the water is 1 inch above the potatoes. Bring the water to a boil over high heat. Reduce the heat to medium-high and boil for 10 to 12 minutes, or until a fork easily pierces the center of the potatoes. Drain the water and transfer the potatoes to a large bowl.
- Instant Pot Method: Place a metal rack in the bottom of your pressure cooker. Add 1 cup of water, then place the potatoes on the metal rack. Cover the pot and set the vent to the SEAL position. Set the cooker to PRESSURE COOK or MANUAL for 8 minutes. When the cook time finishes, quick release the pressure by turning the knob to the VENT position. Once the float valve drops, remove the lid, drain the pot, and transfer the potatoes to a large bowl.
