Papa John'S Sauce

• 2 teaspoons olive oil, or as needed
• 1 sweet onion, diced
• 6 cloves garlic, minced
• 6 (28 ounce) cans Italian-style peeled tomatoes (such as Cento(R) San Marzano)
• 2 tablespoons chopped fresh oregano
• 1 tablespoon salt, or to taste
• 1 tablespoon ground black pepper, or to taste
• 10 leaves fresh basil

1. Pour just enough olive oil into a large pot to coat the bottom; place over medium heat. Cook and stir sweet onion in the pot until it releases some moisture, 1 to 2 minutes. Stir garlic with the onion; cook another 1 minute. Remove pot from heat immediately.
2. Process the tomatoes in a large food mill using medium holes; grind directly into the pot. Bring the tomato mixture to a light simmer over medium-low heat; season with oregano, salt, and pepper. Allow the mixture to simmer 1 hour, stirring regularly.
3. Stir basil leaves into the sauce. Simmer 1 hour more, again stirring regularly.
