Cheesy Oven Fries

Total time: 40 minutes
   A cross between Gratin Potatoes and Oven Fries, these are an easy, minimum fuss, version of cheese potatoes.  They're done in three steps, and at any point can be done ahead/left out of the oven to rest while the rest of the meal catches up...

 Ingredients:

• 2 medium - large potatoes, (12oz, 360gr)
• 1 medium onion  
• 1/2 tsp dried rosemary
• 2oz (60gr) cheese, Gruyère, Cheddar
• 1 tbs olive oil

 Instructions:

• Slice potatoes into thin rounds. 
• Put olive oil in a bowl, add potatoes and toss to coat. 
• Lay the potatoes on a baking sheet, preferably nonstick, in a single layer, but as close together as possible.  Bake in a 400F (200C) oven for 15 minutes.
• Thinly slice onion.
• Remove potatoes and spread onion over the top. 
• Sprinkle with rosemary. 
• Return and bake for 10 minutes longer. 
• Remove and lay cheese on top. 
• Bake for another 5 minutes. 
• When done, use a spatula to remove from pan and serve.
