This potato dish was featured in an old Gourmet magazine as part of a rustic Italian dinner. The meal began with an artichoke and pancetta fettuccine, featured a homemade ciabatta bread, and progressed to the main course of pan roasted veal and these potatoes. I wish I had had the time and the ingredients to make the complete meal, but life is busy right now. My grillmeister did his part by cooking some chicken on the grill on this beautiful day. That gave me the time to putter in the kitchen with this casserole and make some simple frozen vegetables. I find it easier to tackle new dishes when the rest of the meal is simple.
I like the idea of adding tomatoes to a potato dish. They add a vibrancy to the brown potatoes. In this case I had a can of diced tomatoes that worked beautifully. Just be sure the tomatoes are drained well and dry when added to the potato mixture. The potatoes are browned in batches and the casserole can be assembled ahead of time. You could even add more cheese, either Swiss or cheddar, to amp up the flavor. This potato casserole looks good and tastes good. What more could you ask for?

1 medium onion
1 large garlic clove
16 ounce can whole tomatoes
2 pounds russet potatoes (about 6 medium)
5 tablespoons olive oil

In a 12-inch heavy skillet heat 1 tablespoon oil over moderately high heat until hot but not smoking and saute potatoes in 3 batches, turning them, until golden on both sides, add 1 tablespoon oil for each new batch. Transfer potatoes to a bowl as sauteed.
In skillet cook onion in 1 tablespoon oil over moderate heat, stirring occasionally, until softened. Add onion to potatoes with tomatoes, garlic, rosemary, and salt and pepper to taste and toss to combine well.
