Easy Baked Ravioli

Ingredients:
2 Tbsp Olive Oil
1 medium Yellow Onion, chopped
3 Garlic Cloves, minced
Kosher Salt
Freshly Ground Black Pepper
1 ½ tsp Dried Oregano
1 cans (20 ounces) Whole Tomatoes
1 can (28 0unces) Crushed Tomatoes
3 pounds Store-Bought Ravioli
1 ½ cups Mozzarellla , shredded
½ cup Parmesan Cheese, grated

Preheat oven to 425 degrees F. Heat oil in a large saucepan over medium heat. Add onion and garlic, and season with salt and pepper; cook, stirring occasionally, until softened, about 5 minutes. Add oregano and tomatoes. Bring to a boil, reduce heat, and simmer, breaking up tomatoes with spoon, until sauce is thickened and reduced to about 5 1/2 cups, 20 to 25 minutes.

Meanwhile, cook ravioli in a large pot of boiling salted water just until they float to the top (pasta will continue to cook in oven). Drain pasta; return to pot.

Toss sauce with pasta. Pour pasta into a large gratin dish or 9-by-13-inch baking dish, and sprinkle with cheeses. Bake until golden, 20 to 25 minutes. Cool slightly before serving
