Do I Really Need to Peel & Cut the Potatoes Before Boiling Them?

It actually depends totally on you- there’s no difference between peeling the potatoes before boiling them or afterwards.

You also don’t necessarily need to cut them beforehand as well. Cutting them into small chunks just helps lessen its cooking time in the instant pot. 

Which Potatoes are Best for Garlic Mashed Potatoes?

Yukon gold and russet potatoes are both the best ones to opt for when it comes to making mashed potatoes.

Both of these varieties have the most creamy and buttery texture and flavor, and while they might be just a teeny bit pricey, they are totally worth it.

You can also do a mix of both if you’re feeling ambitious. 

Should I Wait For the Potatoes to Cool Down?

While most good recipes need one key ingredient- patience, this is not one of those. Infact, with mashed potatoes, you have to be quick.

Once your potatoes are going boiling, don’t wait for them to cool down before you throw in the other ingredients. Begin work immediately.

That way, all the delicious flavors can stay sealed in and you’ll get that perfect creamy texture to your dish as well. 

Also remember that the potatoes won’t be able to absorb all the liquid at once, so don’t add it all together. Keep adding the stock little by little until you reach the consistency you prefer. 

Another cool tip to make sure your mashed potatoes are creamy is to heat the cream and milk before you add them into the potato mixture. This way, it will be more easily absorbed into the potatoes.

  • Can my dog eat Garlic Herb Mashed Potatoes? The short answer is no. Because this recipe contains garlic and garlic, and other members of the allium family, including onions, contain thiosulfate, which is toxic to dogs but not to humans. Thiosulfate causes oxidative damage to red blood cells, resulting in hemolytic anemia.
  • Can my cat eat Garlic Herb Mashed Potatoes? It is not recommended that you share this food with your cat, because it contains garlic. Garlic given in very small doses from time to time is not harmful to cats, but they are dangerous in large or repetitive doses. These vegetables contain thiosulfate, which can destroy red blood cells in cats and dogs, which can cause anemia.
