Place olive oil and garlic in a cold skillet, then place the skillet over medium heat. As soon as the garlic starts to sizzle and smell fragrant, stir in the tomatoes, oregano, and red pepper flakes. Nestle in the sprigs of fresh basil.
Reduce heat to low and let the sauce simmer for at least 15-20 minutes. Leave it to simmer over low heat for up to 45 minutes if you have that much time.
Remove the basil sprigs and sample the sauce. Add salt and pepper to taste.
Serve right away with your favorite pasta or protein, or store in the fridge for 3-4 days, or freeze for up to 3 months.
