1 Preheat oven to 375°F. Toss the potatoes with 3 tablespoons of olive oil and salt well. Arrange in one layer in a casserole pan or rimmed baking tray and roast until browned, about 50 minutes.
2 When the potatoes are well browned, toss with the matbucha and return to the casserole pan. Continue to roast until the tomato sauce dries out a bit on the potatoes and caramelize, about 10 minutes.
3 Serve with the extra matbucha as an appetizer or side dish.
