  • 8 large russet potatoes
  • 6 cloves garlic finely minced
  • 1/3 cup butter
  • a pinch of black pepper to season
  • 1/2 cup heavy cream or whipping cream heated to scalding but not boiling
  • 1 1/4 cups shredded smoked cheddar cheese
  • 1/4 cup grated parmesan cheese
  • 1 tsp fresh chopped thyme or 1/2 tsp dry thyme optional
  • 1/4 cup melted butter to drizzle on top optional


  1. Preheat oven to 400 degrees F.
  2. Grease a 9x13 glass baking dish well, or one of similar size. I use a large deep dish pie pan as pictured.
  3. Peel and wash the potatoes and cook for about 20 minutes in simmering salted water until fork tender completely through to the centre.

  4. While the potatoes boil, chop the garlic and sauté it for a few minutes in the butter in a small saucepan; just until the garlic softens a little but not browned.

  5. Mash the potatoes so that there are no lumps then mix in the scalded cram and garlic butter along with the grated cheese and a pinch of pepper to season; plus the thyme if you are using it.

  6. Spread the creamy potato mixture into the prepared pan.
  7. Using the back of a fork, draw ridges all across the surface of the potato in both directions, just to create a bit of a craggy surface.

  8. Drizzle on the melted butter.
  9. Bake for about an hour or a little longer. It just depends how crusty you want the edges and bottom of the cooked potatoes.
  10. Allow to cool for about 15 minutes before serving. They are very hot, straight out of the oven.

Recipe Notes

Note: I don't use additional salt with the pepper to season these potatoes before baking. Bothe the butter and the parmesan cheese contain adequate salt to season the potatoes well.
