Before You Begin
Prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Cook rotini in salted boiling water until al dente (6–8 minutes). Drain thoroughly.
Heat olive oil over medium heat. Sauté onion and garlic for 3–4 minutes until softened.
Add cherry tomatoes, Italian seasoning, salt, and pepper. Cook 1–2 minutes until slightly softened.
Combine pasta with sautéed vegetables, artichokes, and olives. Toss gently.
Transfer to prepared baking dish and distribute mozzarella evenly on top.
Bake 20–25 minutes, until cheese is melted, lightly golden, and the center is heated through and bubbling.
Let rest 10–15 minutes before serving.
