Description

Potatoes gratin with heaps of gruyere cheese, rosemary infused cream, caramelized onion and roasted tomato.

Ingredients

Scale
  • 1/2 lb yukon gold potatoes, thinly sliced
  • 1/2 white onion, chopped
  • 1/4 cup heavy cream (because I love myself)
  • 1/2 cup grated Gruyere (approximate)
  • 1/3 cup grated Parmesan (approximate)
  • 1 whole tomato, sliced
  • 2 sprigs fresh rosemary 
  • Olive Oil
  • 1 large clove of garlic, minced
  • Salt & pepper to taste
  • 1 tbsp butter (optional)

Instructions

  1. Preheat oven to 400 degrees.
  2. Put a pan with about a tbsp of olive oil over medium heat.  Add minced clove of garlic and let cook until aromatic. Add chopped onion.  Season with salt and pepper to taste.
  3. Allow the onion to caramelize, letting them sit and mixing them in long enough intervals to let them brown without burning.  
  4. While onions are caramelizing, heat the heavy cream in a small sauce pan over medium heat.  Add rosemary sprigs and allow them to infuse while you prepare the rest of the dish.
  5. Use butter to grease the pan you’re using to bake your gratin to prevent sticking (and add some delicious fat that will allow the sides to brown and get crisp). 
  6. Do a quick season of your potato slices with a dash of salt.  Toss to coat.  
  7. Start to layer your thinly sliced yukon potatoes in an overlapping structure.  After one layer, add half the caramlized onions and a few slices of tomato.  Add about a third of the grated Gruyere and Parmesan.
  8. Add a second layer of overlapping potato slices, followed by the remaining caramlized onion, a few more slices of tomato, and another third of the grated Gruyere and Parmesan.
  9. Before you add the final top layer, remove the rosemary sprigs from your heavy cream and pour over the entire dish.  The extra moisture will help cook the interior while it bakes.
  10. Top the dish off with the final layer of potatoes, a few slices of tomato, and the remaining grated cheese.  Make this layer pretty for presentation purposes.
  11. Put baking dish in oven for ~40 minutes, depending on your oven.  You’ll know it is down when the interior is tender (text with a toothpick or fork).
  12. Let cool, and serve warm!
