Cut 3 (1/3-inch-thick) lengthwise slices from center of eggplant and reserve remainder for another use. Brush 2 large shallow baking pans with 1 tablespoon oil total, then arrange eggplant, zucchini, and bell peppers in 1 layer in pans. Brush vegetables with remaining 2 tablespoons oil and sprinkle with pepper and 1 1/4 teaspoons salt. Roast, switching position of pans halfway through roasting, until eggplant and zucchini are browned and tender, 15 to 20 minutes total, then transfer eggplant and zucchini to a plate.

While vegetables roast, cook garlic in butter in a 1 1/2- to 2-quart heavy saucepan over moderate heat, whisking frequently, until fragrant, about 30 seconds. Whisk in flour and cook, whisking constantly, 2 minutes. Add milk in a slow stream, whisking, and bring to a boil, whisking constantly. Reduce heat and simmer, whisking frequently, 8 minutes (sauce will thicken slightly when it first comes to a boil). Remove from heat and cool béchamel sauce, stirring occasionally, 10 minutes. Stir in cheeses, basil, and remaining 1/2 teaspoon salt.
