Heat a medium saucepan over low-medium heat. Once hot, add olive oil and garlic and sauté until fragrant — about 1 minute. Add red pepper flakes and stir to infuse flavor. Turn down heat if cooking too quickly.
Add remaining ingredients (crushed tomatoes, oregano, basil, salt, and maple syrup) and bring to a simmer over medium heat.
Once simmering, allow to cook for 10-15 minutes or until slightly reduced. If splattering, reduce heat and cover. When done cooking, the flavors should be deep and well integrated. Taste and adjust as needed, adding more maple syrup for sweetness, salt for overall flavor, red pepper flakes for heat, or oregano or basil for more herby flavor.
