Heat a skillet over medium heat and add the olive oil.
Once the oil is hot, add the finely chopped onion and sauté for 3-4 minutes until translucent.
Add the minced garlic to the skillet and sauté for an additional 1-2 minutes until fragrant, being careful not to let it burn.
Transfer the sautéed onion and garlic mixture to the slow cooker.
Add the canned crushed tomatoes, tomato paste, granulated sugar, dried oregano, dried basil, red pepper flakes, salt, and black pepper to the slow cooker.
Stir everything together until well combined.
Cover the slow cooker and set it to cook on low for 4 hours or high for 2 hours, stirring occasionally to prevent anything from sticking to the sides.
After cooking, use a wooden spoon to gently crush any remaining tomato chunks for a smoother texture (optional).
Stir in the fresh chopped basil and allow the sauce to sit in the slow cooker (still on warm) for 10 minutes to meld the flavors.
Taste the sauce and adjust seasoning with additional salt or pepper, if needed.
Serve the marinara sauce over your favorite pasta, use it as a pizza sauce, or as a dipping sauce. Optionally, sprinkle with Parmesan cheese before serving.
