How to make garlic mashed potatoes?

Start making your cheesy garlic mashed potatoes by adding your potato and salt to a medium stock pot, cover with water. Bring to a boil and cook until potatoes are soft, about 15-20 minutes.
Remove water by pouring it out into a strainer. Return potatoes to stock pot.

Prepare garlic by removing garlic cloves from outer paper layers, cut ends off each clove, smash clove with the side of a large knife. This will separate the outer paper layers from the garlic.

Pour olive oil into a warm saucepan, then add garlic cloves. Cook over med-low heat, covered for 10-15 minutes.
Remove water by pouring it out into a strainer. Return potatoes to stock pot.

Add Greek yogurt, milk, cheddar cheese, garlic, and salt & pepper to potatoes. Mash with a fork or potato masher. Top your cheesy garlic mashed potatoes with fresh or dried chives. Serve immediately.

Expert Tips
- Cook potatoes in an Instant pot, but like all Instant Pot recipes, the pressure cooking time may be short, but it takes time to get up to pressure and to release the pressure. Plan on at least 30 minutes to cook these potatoes.
- Check doneness of potatoes by piercing one with a fork. If it slides in and out easily, your potatoes are done. If potatoes are not done, set timer to another 5 or so minutes, and continue until potatoes are soft.
- Use a fork or potato masher to mash the potatoes directly in the Instant Pot for your cheesy garlic mashed potatoes.
- I kept the skins on for extra texture, ease, and nutrients. You can peel them or leave them on, either way.
FAQ
Higher starch potatoes like russet or yukon gold potatoes are best, they make the creamy and fluffy cheesy garlic mashed potatoes and other mashed potato recipes.
Either you used potatoes that aren't as high in starch as russet or yukon gold (they require more mashing, which can make them gluey), or they got overcooked and lost some of that starch in the cooking water.
If your cheesy garlic mashed potatoes got too thinned out, you could add a little more Greek yogurt, or slowly add a bit of flour or cornstarch (remove some of the liquid to add the thickener to, and add it back in to the potatoes) to your potatoes.

How can I repurpose the best garlic cheesy mashed potatoes?
- Make Gnocchi with leftover cheesy garlic mashed potatoes. Gnocchi does take time, but it's super easy & fun to make.
- Top stewed vegetables to make a shepherds pie.
- Add leftover cheesy garlic mashed potatoes to a soup to make it even creamier.
What can I make with the leftover ingredients?
- Potatoes: rustic potato & brussels sprouts au gratin, no-mayo potato salad
