Instant Pot Garlic Mashed Potatoes

If you are looking for the creamiest, smoothest, magnificent and perfect flavor-designed Mashed Potatoes ever, look no further. 

One of the best things about this recipe is that is allows you to alter how thick or creamed these Garlic Mashed Potatoes are based on your preference. There’s no right or wrong here, folks! 

The Instant Pot is going to help you achieve this so quickly and effortlessly, those you serve it to wouldn’t believe you since they’ll be singing your praises the night through. Goes PERFECT with my BREAK-THE-INTERNET Pot Roast!

Here’s How I Made It! (scroll for the written recipe): 

Begin by adding in a lovely mix of baby white and red potatoes to the Instant Pot. 

…along with some chicken or garlic broth… 

…and some cloves of garlic. Secure the lid and cook at high pressure. 

In the meantime, take a bunch of chives… 

…and chop ’em up. 

Once the lid comes off the pot, mash the potatoes with a good potato masher

They may appear a bit soupy at first, but this is normal. The potatoes will absorb the broth as they’re mashed. 

See? When done, it’ll look like this. 

It’s time to make these mashed potatoes super creamy. Add in a stick of butter… 

…and mix until it melts into the potatoes. 

Then, take some Boursin (or cream cheese)… 

…and mix into the potatoes until melded. 

Season it up with some garlic salt… 

…black pepper… 

…and chives. 

Stir together well… 

…and you’ll have the creamiest, most luxurious Garlic Mashed Potatoes ever! 

Spoon into a serving dish… 

…and admire the silkiness of these beautiful potatoes. 

Show it off… 

…try it out… 

…and AWWW YEAH – you’ve done it again! The best mashed potatoes of all time to accompany any meal or just eat on its own!

One of the things I absolutely love most are creamy, smooth and slightly chunky Garlic Mashed Potatoes. The secret to the best ever is the balance of consistency and adding in a spreadable herb cheese!

Prep Time 5 minutes
Cook Time 15 minutes
Total Time 20 minutes


  • 5 lbs of baby white and baby red potatoes mixed (so 2.5 lbs of each), whole and skin on (yukon gold or larger red potatoes work great too – just cut them into quarters)
  • 3 cups of garlic or chicken broth (I used 3 tsp of Garlic Better Than Bouillon plus 3 cups of water. NOTE: This will make for a very creamy mashed potato – almost liked a creamed potato – which is just how I like it. If you want it thicker, only use 2 cups of broth. If you want it very thick, use only 1.5 cups of broth. See the yellow “Jeffrey Sez” section for more info)
  • 6 whole cloves of garlic
  • 1 stick (8 tbsp) of salted butter
  • Two 5.2 ounce packages of Boursin (any flavor OR 8 ounce brick of cream cheese if you can’t find Boursin which is in the deli section of most markets and is sold in Costco in 3 packs)
  • 1 tbsp of garlic salt
  • 1/2 tbsp of black pepper
  • 1 bunch of chives, sliced
  • 1/4 – 1/2 cup of grated Parmesan cheese (optional)


  1. Add the potatoes, the broth and the garlic (in that order) to the Instant Pot and hit “Manual” or “Pressure Cook” High Pressure for 15 minutes. Quick release when done
  2. Using a potato masher, mash the potatoes up in the pot. It may appear soupy at first, but once fully mashed, the potatoes will absorb all the broth
  3. Add in the butter, Boursin (or cream cheese), garlic salt, pepper, chives and Parmesan cheese (if using). Stir until well combined
  4. Enjoy! Goes GREAT with my acclaimed Pot Roast

Jeffrey's Tips


Using 3 cups of broth with the potatoes will make for a very creamy mashed potato, which is just how I like it. If you want it thicker, only use 2 cups of broth. If you want it very thick, use only 1.5 cups of broth.

To the point above, if you used less broth than 3 cups when mixing the ingredients together after mashing, you may find you want it creamier. Add in 1/2 – 1 cup of heavy cream or half & half to achieve that.

Leftovers will thicken in the fridge due to the Boursin or cream cheese. Simply place in microwave or stove and add a little cream to loosen it up and blend.

In the market for a good potato masher? This one is great!

      Idk if he will ever answer your question…all I can tell you is you will definitely want leftovers! They are amazing! We make potato pancakes when we’re tired of just mashed and I have froze them also. Definitely worth making the full recipe.

    • Hannah

      Seconding this! I’ve made the whole 5lb version for 2 people and while we did finish it, it took about 4 days. I would love to halve it.

    • Joel

      I’m a single person. What I do with leftovers is put them into several 1 quart freezer bags. I weigh each out at about 12 oz or 350 ml for each bag using a scale. I then flatten them out and express as much air as possible. I stack them in my freezer. To reheat in the microwave can be a trick because it will seem like they’re not going to come back together for quite a while…until they do. I thaw them, put them into a glass bowl and reheat 2 minutes on 50% power x 3, stirring between each. It works wonderfully

      i would do them separately. some for mashed and others, not cooked quite as long for potato salad. Have done this myself and perfect. I use half a bag 2.5 lbs for 2 people and probably get 3 meals out of it. I love that no milk, so fewer calories. I did add 1 tbsp sour cream, and 1 tbsp of boursin. I thought 1 full package would be too strong.

    Tried these today for the first time. I halved the recipe. After the quick release I added the seasoning and used a hand mixer to “mash” up the contents similar to what you recommend for shredded chicken careful not to overbeat. The technique worked quick and easy. Added in the butter and cream cheese. BEST mashed potatoes I’ve ever had. Just delicious! Thank you for another great recipe.

  2. Carrie

    I need to triple this recipe. Can I do that all at once or should I do three separate tines? If I can do all at once, do I need to adjust cook time?

    You hit ANOTHER ball outta the park with this one Jeffrey! Amazing. I had an emergency with my dog, shortly after my pot came to pressure, and I rushed out the door. Came back two hours later, the pot was still on warm, potatoes were soft, and much of the broth was absorbed. Mashing was extremely easy, lol Added the rest of the ingredients, and still absolutely amazing! Thank you! Can’t wait for your comforts book to arrive. What could be more comforting than these potatoes?!?!

    All I can say is… burp! Made these tonight paired with a sous vide chuck roast and the entire meal was delicious! Thanks for the recipe!
