Spanish Rice with Zucchini

Preheat oven to 350°F.

In a 2-quart flameproof casserole or saucepan, heat oil over moderately high heat until hot but not smoking. Add onion and garlic. Reduce heat to moderately low and cook onion mixture, covered, stirring occasionally for about 4 minutes, or until softened. Increase heat to moderate and add rice. Cook rice, stirring, 3 minutes. Add broth and bring to a boil, covered. Remove from cooktop to oven.

Bake rice, covered, in middle of oven about 20 minutes, or until liquid is absorbed. Stir in zucchini and let stand, covered, 5 minutes.
