Preheat oven to 400°F and prepare a 9x13-inch baking dish.
In a small bowl, mix paprika, thyme, rosemary, garlic powder, salt, and pepper. Set aside.
In the baking dish, combine rice, broth, water, garlic, sliced carrots, butter, and 1 1/2 teaspoons of the seasoning mix. Stir well and cover tightly with foil. Bake for 20 minutes.
While rice bakes, toss onion, bell pepper, cauliflower, broccoli, zucchini, and olive oil with remaining seasoning mix.
Remove rice from oven, increase heat to 425°F, and arrange vegetables over the rice. Bake uncovered for 30 minutes.
Fluff the rice with a fork and mix with vegetables before serving.
