Place onions in a lightly oiled, shallow 2-quart baking dish. Toss with oil, salt and pepper. Cover and bake for 45 minutes. Uncover and bake until tender and just starting to brown, about 10 minutes longer. Stir in currants, vinegar and capers.
Before serving, spread 1/2 teaspoon olive paste or chopped olives over one side of each toasted piece of baguette. Top with 2 teaspoons of the onion confit.
