Description

These Rosemary Garlic Mashed Potatoes are infused with aromatic rosemary and sweet, mellow garlic for incredible depth of flavor. Made with a mix of Russet and Yukon Gold potatoes, cooked in chicken stock, and whipped with cream and butter for a silky, cloud-like texture. This elevated side dish is perfect for Thanksgiving, Christmas, dinner parties, or any meal that deserves something special.

Ingredients

For the Infused Cream:

1 cup heavy cream
4-5 whole garlic cloves, peeled
2 sprigs fresh rosemary

For the Mashed Potatoes:

3 lb potatoes (I use a mix of Russet + Yukon Gold, peeled)
4 cups chicken stock (or enough to cover potatoes)
10 tbsp salted butter, melted
Salt & white (or black) pepper, to taste
Fresh parsley, for garnish (optional)

Substitution Notes:

All Russet or all Yukon Gold works too! Russets give you fluffier mash, while Yukons are creamier and more buttery.
No chicken stock? Use vegetable stock or even water with a bouillon cube.
Unsalted butter? Absolutely fine—just add a bit more salt to taste.
White pepper vs. black: White pepper keeps the mash looking pristine, but black pepper adds a nice visual pop and I love it!

Instructions

Step 1: Infuse Cream with Garlic & Rosemary

Throw your cream, whole garlic cloves (don’t peel them weird or anything just drop them in), and rosemary sprigs into a small pot. Turn the heat to medium until you see bubbles starting, then immediately turn it down to the lowest setting your stove has. Set a timer for one hour. I KNOW. An hour seems insane. But you’re literally doing nothing—I usually start this first then go do laundry or watch TV or meal prep other stuff.

Step 2: Cook the Potatoes

While that cream’s doing its magic, peel your potatoes. I hate peeling potatoes with a burning passion but it’s gotta be done. Cut them into chunks—I’m not measuring, just like… big enough that they’ll cook evenly but small enough that you’re not waiting forever. Maybe lemon-sized pieces? I don’t know, use your judgment. Toss them in your big pot.

Step 3: Drain & Mash

Dump the whole pot into a colander in your sink. Shake it around to get the water off. I usually scoop out like a cup of that cooking water first just in case but 9 times out of 10 I don’t use it. Put the drained potatoes back in the pot and stick it on low heat for maybe 30 seconds. This evaporates off any extra water clinging to them so they’re not all soggy.

Step 4: Finish with Mixer

THIS is where the magic happens and also where you can screw it up so pay attention. Get your hand mixer and turn it on medium. Start beating those potatoes. They’ll go from lumpy to smooth to actually FLUFFY and it’s so satisfying to watch. Here’s the thing though—you gotta STOP. I made them gluey exactly one time because I thought “oh more mixing must be better” and ended up with what looked like paste. Beat them for like a minute, maybe a tiny bit more until they look gorgeous and fluffy, then STOP RIGHT THERE.

Taste them now. Add salt. I add like way more than seems reasonable but potatoes need a lot of salt. Add pepper. Taste again. Keep going until they taste good. This is not the time to be scared of seasoning.

Step 5: Serve

Scoop them into whatever serving bowl you’re using. I like doing that thing where you make a well in the middle and drop a big pat of butter that melts down into it because it looks nice. Throw some chopped parsley on top if you remembered to buy parsley (I usually forget). Serve them right away while they’re hot because that’s when they’re best.

Notes

Keep Everything Warm: Cold cream will cool down your potatoes. Make sure your infused cream and melted butter are still warm when you add them.
Use a Ricer for Ultimate Smoothness: If you have a potato ricer, use it before the mixer step for the silkiest texture imaginable.
Save Some Cooking Liquid: If your mash seems too thick, add a splash of the reserved cooking liquid or extra cream to loosen it up.
Avoid Overpowering Rosemary: Trust me on this—the infusion gives you PLENTY of rosemary flavor. Don’t add extra sprigs or it’ll taste medicinal.
Room Temperature Cream Works Too: If you’re short on time, let the infused cream cool to room temp and gently reheat it before adding to potatoes.
