Heat the olive oil in a large saucepan set over medium heat.
Add the diced onion. Cook, stirring occasionally, until the onion softens and becomes translucent, 6 to 8 minutes. If the onions are drying out as they cook, add a teaspoon or two of water.
Add garlic, oregano, red pepper flakes, salt and pepper. Cook, stiring, for 1 minute.
Pour in the crushed tomatoes (both cans), vegetable broth, water and rice. Stir to combine. Bring the mixture to a boil, then reduce the heat to medium-low (or whatever heat allows the mixture to cook at a simmer).
Cover and simmer until the rice is tender, 30 to 40 minutes. Stir a couple of times during the cooking time, scraping the bottom of the saucepan with a wooden spoon to ensure that the rice isn’t sticking.
Season to taste with salt and pepper. Stir in the basil and parsley. Serve.
