Roasted garlic mashed potatoes are so easy to make, and can even be made ahead of time. Add some roasted garlic to your mashed potatoes for a tasty change!
I’ve mentioned before that mashed potatoes are not my strong suit. I’ve made lumpy mashed potatoes so many times that my family has started to not expect much when mashed potatoes are on the menu.
It’s true. I’ll admit it.
I’ve just never been that great at making mashed potatoes.
But I like them. So clearly I needed to remedy that situation.
I’ve discovered that the Instant Pot makes mashed potatoes easy. So if you have the same problem and always seem to undercook your potatoes so they just don’t mash easily, make them in the Instant Pot. Five minutes of cook time and they are perfect every time.
Or just boil them long enough if you’re making them on the stove. Cook them longer then you think you need to. Trust me on this.
They need to literally be falling apart or your mashed potatoes will have lumps. I’ve learned this the hard way. If you think they’re done, cook them a little longer!
But in my mind, Instant Pot mashed potatoes are where it’s at. I don’t see myself making them any other way from now on.
I’ll change them up by making roasted garlic mashed potatoes though. Roasted garlic is so tasty, and adding it to mashed potatoes makes for the perfect side dish.
Roasted garlic has a milder flavour then raw garlic so don’t be concerned that this recipe calls for a whole head of garlic. It’s delicious this way, I promise. If you like garlic, you will love these roasted garlic mashed potatoes.
How do you roast garlic?
Roasting garlic in the oven is super easy and is so much tastier in mashed potatoes then raw garlic. The flavour is much milder and doesn’t have the bite of raw garlic. I’ve written an entire post on how to roast garlic, so head there to check out all the details, along with a bunch of ideas for using it!
What potatoes are best for mashed potatoes?
Higher starch potatoes, such as russet or yukon gold potatoes, produce the smoothest, fluffiest mashed potatoes. I typically use russet potatoes – mostly because that’s what my father-in-law told me to use, and he makes amazing mashed potatoes so he must be right!
How many potatoes is 2 pounds?
2 pounds of potatoes is about 6 medium russet potatoes. If you have a kitchen scale, the best way to make sure you’re using the right amount is simply to weigh your potatoes and use approximately 2 pounds for this recipe. You don’t need to worry about being too exact here – if my 6-7 potatoes are 2.2 pounds, I still use all 6 or 7 of them!
How many potatoes should you make per person for mashed potatoes?
Typically you should use 1/3-1/2 pound of raw potatoes per person for mashed potatoes. Obviously this will depend on the people – but it’s a good starting point. This recipe can be easily increased to cook for more people, although as it’s written it makes about 4 servings.
Can you make mashed potatoes ahead of time?
Yes! Mashed potatoes can be made a day or two ahead of time and refrigerated. To reheat them, mash them with the milk and sour cream and then refrigerate.
When you want to reheat them, place them in the buttered crock of a slow cooker and reheat on low (or warm, depending on how hot your slow cooker is) for 3-4 hours. Mine runs pretty hot, so I do low for 1-2 hours and then lower it to warm. When you are ready to serve, add the butter and whip them until smooth.
How to make roasted garlic mashed potatoes:
- You can roast your garlic a day or two ahead of time and keep it in a sealed container in the fridge. Or start it roasting and then peel and cook your potatoes while it’s in the oven.
- This recipe does call for a whole head of garlic. It’s okay, really. When you roast garlic, it has a much milder flavour then when it’s raw. I will say though, that if you are making these mashed potatoes ahead of time, the roasted garlic flavour tends to intensify. So if you’re serving them immediately, the whole head of garlic will just add a nice garlic flavour. But if you are making them ahead and they’re refrigerated for a couple of days, it will be more pronounced. We still like them with a stronger flavour, but if you don’t want that, either add your garlic when you reheat them, or use a little less.
- If you’re boiling your potatoes, make sure to cook them long enough. They should be falling apart when they’re done.

- 1 head of garlic
- 2 teaspoons olive oil
- 2 pounds russet potatoes, peeled and quartered
- 1/4 cup milk
- 1/4 cup sour cream
- 1/4 cup butter
- 1/2 teaspoon salt
- pinch pepper
- Preheat the oven to 375 degrees F.
- Slice the top off of the head of garlic to expose the cloves. Set the garlic on a piece of aluminum foil and drizzle with olive oil.
- Wrap the garlic in the foil and roast in the preheated oven for 40-45 minutes, or until the garlic cloves are tender.
- Let cool until they are cool enough to handle.
For the Instant Pot:
- Place the peeled and quartered potatoes in the Instant Pot.
- Add 1 cup water, place the lid on the Instant Pot and lock it into position. Make sure the vent is in the sealing position.
- Cook the potatoes at high pressure for 5 minutes.
- Quick release the pressure and drain the water from the pot.
For the stovetop:
- Place the potatoes in a large pot of water and bring to a boil on the stove.
- Boil for 20 minutes, or until the potatoes break apart easily when pierced with a fork. Make sure to cook the potatoes long enough, or you may end up with lumpy mashed potatoes - they should fall apart easily.
- Drain the water from the potatoes.
After cooking the potatoes and garlic:
- Mash the potatoes with a potato masher.
- Squeeze the cooled, roasted garlic cloves out of the skin and add them to the potatoes.
- Add the milk, sour cream, butter, salt, and pepper and continue mashing with the potato masher until the potatoes are smooth and creamy. You can also use an electric mixer to whip them if you like and make sure no lumps remain.
- If you want to make the potatoes ahead of time, mash them with the milk and sour cream and refrigerate, then warm them up (warm setting on a slow cooker or Instant Pot) and whip them with the butter right before serving.
The cook time refers to how long it takes to roast the garlic and assumes that you are cooking the potatoes at the same time. If you are boiling your potatoes, it will take about 20 minutes for them to cook until tender. If you are cooking them in the Instant Pot it takes 5 minutes to cook them, plus the time for the pot to come to pressure, about 10-15 minutes.
If you want to make the potatoes ahead of time, mash them with the milk and sour cream and refrigerate, then warm them up (warm setting on a slow cooker or Instant Pot, or on low heat in the microwave) and whip them with the butter right before serving.
