Learn these easy tricks to make the absolute best creamiest roasted garlic mashed potatoes that make for the perfect side dish to any main entrée.
Believe it or not, there’s an art, even making something as simple as mashed potatoes. It’s understanding these simple techniques so you can make absolutely anything homemade, which only takes a few more minutes and steps while always rendering the best food out there.
What Is the Best Potato for Mashing?
Here is a list of the best potatoes for mashing.
- Golden Yukons – These potatoes are a cross between the North American white potato and a South American yellow potato. They have the perfect combination between dry and moist and make for a fantastic mashed potato.
- Russets – These large brown potatoes, which are often referred to as Idaho potatoes, are high in starch and on the drier side but still make a great mashed potato as well as French fries.
- Red New Potatoes – These are smaller potatoes with red skin and have the highest sugar content of these 3 potatoes and are a great combination of dry and moist. I love using these with the skin on in a mashed potatoes recipe.
How to Make Garlic Mashed Potatoes
1. Cook together garlic cloves and olive oil over low heat until browned and tender, about 20 minutes. This process is called garlic confit
2. Strain the oil from the garlic cloves and set both aside.
3. Heat heavy cream and unsalted butter sticks together in a small saucepot over low heat until melted. You just want to keep the cream and butter warm.
4. Peel and quarter Yukon gold potatoes and place them in a large pot with water.
5. Add garlic cloves and salt to the pot with the potatoes and water.
6. Cook the potatoes over medium-high heat and at a low boil until they are soft and tender, about 10-12 minutes.
7. Strain and transfer the potatoes to a food mill and rice them with the roasted garlic cloves until they are mashed through the food mill.
8. Add the hot cream and butter, some drained roasted garlic olive oil, sour cream, salt, and pepper to the mashed potatoes and mix until incorporated.
9. Serve with more melted unsalted butter and chopped chives for garnish.
Mashed Potatoes With the Skin On
You can absolutely use potato skins in your recipe. I advise you to wash and scrub the outside skins of them before cutting them and boiling them.
There are some significant nutrients such as iron and potassium found in potato skins, and are certainly an added health benefit to leaving them on in a garlic mashed potatoes recipe.
How Do You Make Them Thicker?
The absolute biggest contributor to ensuring you can make mashed potatoes thicker is making sure they are cooked properly. If you overcook them while boiling them, they will only be able to hold so many added ingredients such as butter, cream, or sour cream.
With that being said, if you really love thick garlic mashed potatoes, you can add in any of the following until the desired amount of thickness is achieved:
- Potato Flakes
- Potato Starch
- Corn Starch
- Arrow Root
Just cook them correctly and add anything you want to them, and they will remain thick.
Healthy Garlic Mashed Potatoes
A way to keep this recipe healthier would be to swap these ingredients.
Butter <-> Yogurt
Heavy Cream <-> Fat-Free Milk
Garlic Olive Oil <-> Plant-Based Oil or Butter
Make-Ahead and Storage
Make-Ahead: You can make these up to 1 hour ahead of time. Just keep covered and warm over very low heat.
How To Reheat: To reheat the garlic mashed potatoes, add your desired portion to a small saucepot with a little butter or milk and heat over low heat until hot. In addition, you can simply add them to the microwave and heat them until hot.
Storing and Freezing: They can be stored in the refrigerator covered in plastic for up to 4 days. They can also be frozen and covered for up to 2 months. However, they will lose quite a bit of moisture and flavor if frozen.
chef notes + tips
- If you notice the mashed potatoes have sucked up all the cream and oil and are thick, feel free to add more oil and sour cream to help thin out a little bit
- You can use a stand mixer, hand mixer, or a manual hand masher when mashing the potatoes.
- In my own humble opinion, the best potato out there for mashing are Yukons because of their balance of sugar to starch.
