Roasted Garlic Mashed Potatoes

We’ll get to the cheesy part in just a sec, but firstly let’s talk about roasted garlic.

If you’ve been a reader of mine for a while, you’ll have realised I’m obsessed with roasting garlic. Roasting garlic really changes both the texture and flavour of the garlic into something sweet and caramelized. Turns out it goes pretty nicely in mashed potatoes.

For a more comprehensive tutorial on how to roast garlic (it’s so easy, promise) check out my Oven Roasted Garlic. But for now – 

How to roast garlic (quick summary)

  1. Slice the tip off your garlic bulb to expose the cloves.
  2. Drizzle with olive oil.
  3. Wrap in foil and bake until golden and caramelized.

Should look a little something like this:

Cheesy Roasted Garlic Mashed Potatoes

I mean mashed potato with roasted garlic is great, but let’s take things to the next level shall we?

Cheesy mashed potato brings me right back to my childhood (and has stayed with me through adulthood, clearly). You can’t beat it! The perfect side dish for just about anything.

How to make Cheesy Roasted Garlic Mashed Potatoes (quick summary)

  1. Boil your potatoes until fork tender.
  2. Mash in butter and roasted garlic.
  3. Stir in cheese, cream and seasoning.
Top Tip #1 – Use a nice strong cheddar! Stay away from milder cheeses, they won’t pack the punch a sharp cheddar does.

Baked Mashed Potatoes

From there, honestly? It’s already gonna taste great. But if I’m making mashed potatoes I’ll always bake them in the oven.

I find that when you bake mashed potatoes, especially if they’re loaded with cheese and/or roasted garlic, it marries the flavours together a little more. You also get that gorgeous golden top, which is always to die for.

How to bake mashed potatoes (quick summary)

  1. Scoop mashed potatoes into a suitably sized baking dish.
  2. Top with melted butter (or extra cheese!).
  3. Bake until golden and bubbly.
Top Tip #2 – Baking will loosen the mashed potatoes quite considerably. Let them sit for 5 mins to restore shape and you’ll be good to go.

And there we have it! Cheesy garlicy mashed potatoes are yours for the taking.

Once out the oven, I love to top with finely diced fresh chives. Try to not think of these as just garnish; they actually add gorgeous flavour and marry with the roasted garlic perfectly.

Ingredients (check list):

  • 2lb / 1kg White Potatoes, peeled & diced into chunks

Quick 1 min demo!


a) Butter - I actually use salted butter for this recipe. There's nothing worse than bland mash potato, so if you're using unsalted butter, season, season again then season some more.
b) Roasted Garlic - For a more comprehensive guide to roasting garlic check out my How to Roast Garlic post.
c) Baking - In all honestly the mash will taste great before you bake it, but when you do bake it all the flavours just marry together a little better. It also creates a gorgeous crust and turns the potato underneath nice and bubbly. If you're feel extra cheesy then feel free to add extra cheese on top before you bake!
d) Chives - Try not to think of these a merely garnish, they actually add gorgeous flavour to the mash.
e) Resting - When the mash comes out the oven it will be slightly sloppy, but it does firm back up after resting so don't fear.
