How do I make cheesy garlic mashed potatoes?
Add 1 cubed potato and ½ teaspoon 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.
Expert Tip: You can also 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.
Prepare garlic by removing 3 garlic cloves from outer paper layers. Next cut ends off each clove, and smash clove with the side of a large knife. This will separate the outer paper layers from the garlic.
Pour 1 tablespoon olive oil into a warm saucepan, then add garlic cloves. Cook over med-low heat, covered for 10-15 minutes.
Expert Tip: 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.
Remove water by pouring it out into a strainer. Return potatoes to stock pot.
Add ½ c Greek yogurt, ½ c milk, 1 c cheddar cheese, garlic, and salt & pepper to potatoes. Mash with a fork or potato masher. Top with fresh or dried chives. Serve immediately.

- Use a fork or potato masher to mash the potatoes directly in the Instant Pot.
- I kept the skins on for extra texture, ease, and nutrients. You can peel them or leave them on, either way.
FAQ
What is the best potato for mashing?
Higher starch potatoes like russet or yukon gold potatoes are best, they make the creamy and fluffy mashed potatoes.
Why are my mashed potatoes gluey?
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. So don't overcook them, and make sure to choose the right potatoes!
How can I thicken my mashed potatoes?
If your 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 these mashed potatoes?
- Make Gnocchi. Gnocchi does take time, but it's super easy & fun to make.
- Top stewed vegetables to make a shepherds pie.
- Add 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
- (cheese) veggie quesadilla, chicken burger, breakfast tacos, egg roll-up
- (Greek yogurt) yogurt bowl, overnight oats, lentil stroganoff, pumpkin cake, broccoli salad with grapes

Thanks for the tips on how to avoid gooey potatoes. I've never been able to figure out why they are sometimes sticky and other times not. The Greek yogurt is a brilliant addition too!
