sour cream onion mashed potatoes

I’m sort of known in my family for having a weird obsession… Sour cream. I just LOVE IT. I love it on baked potatoes, or even as a dip for fries. I love it it as a topping for nachos. I love to spoon it into tacos and fajitas and let it melt in and cool everything down. I won’t have chili without it. Mr. Veggie is indifferent, and sometimes he won’t even bother putting it in his fajita. “I’m not in the mood for dairy” he will say. Hmmm. I don’t understand.

So you’re probably thinking I’m about to tell you how to pour an obscene amount of sour cream into mashed potatoes and call it dinner (because, ya know, I do things like that).

But, as it happens, inhaling copious amounts of full fat sour cream is also a great way to pile on some extra pounds, so lately I have made an effort to get my kicks from elsewhere. And I found that with a little bit of a training, low fat yogurt is starting to hit the spot. A low fat yogurt that has a strong tang to it and no added sugar or thickeners (I like Rachels and Yeo Valley for this). So that is what the recipe actually contains (but yogurt and onion wasn’t such a good headline. It’s not a thing.).

What I am going for  is a nod to the sour cream and onion Pringles that I loved so dearly before I knew better. Using low fat yogurt doesn’t make it healthy. But you get the tang and moisture that you need with less fat than if you used sour cream. There is still cheese and butter to enhance the flavour- these things weren’t negotiable (I tried). And the onion and garlic powders I used aren’t the freshest flavour sources, but they are strong and salty enough not to drown in the potato.

So basically, its a little bit healthier than it might have been, and I’m just going to call that a win!

  • 6 medium sized potatoes
  • 1 cup (240 ml) yogurt, low fat or fat free will work fine
  • 2 Tbsp onion powder
  • 1 Tbsp garlic powder
  • 2 – 4 Tbsp butter
  • 1.5 cups (170 g) grated cheddar cheese, you need one with a strong flavour to cut through
  • Salt and pepper


  • Chop the potatoes into large chunks
  • Boil the potatoes in a saucepan for about 20 minutes until soft
  • Drain the potatoes and empty into a bowl. Set aside.
  • In the same saucepan, over a very low heat, melt the butter and add the onion and garlic powders, stirring until they are incorporated into the butter, about 30 seconds.
  • Remove the saucepan from heat and rice the potatoes directly into the pan with the melted butter (if you don’t have a ricer, you can mash them in, but promise me you will at least consider buying a cheap potato ricer!!)
  • Mix the potatoes and butter together
  • Add some salt and pepper if you wish
  • Put the pan back on low heat, and add the yogurt and cheese to the saucepan. Stir quickly, until the yogurt is mixed through and the cheese has melted, and the potato will start to come away from the sides of the pan a little more easily
  • Serve it, love it!
