Ingredients

• 2000 grams Fresh tomatoes (e.g., Roma or plum)
• 4 units Garlic cloves
• 1 unit Yellow onion
• 2 tablespoons Extra virgin olive oil
• 2 tablespoons Tomato paste
• 1 teaspoon Dried oregano
• 1 teaspoon Dried basil
• 1 teaspoon Salt
• 0.5 teaspoon Ground black pepper
• 1 teaspoon Sugar (optional, to balance acidity)
• 1 unit Bay leaf
• 4 units Fresh basil leaves (optional, for garnish)

Directions

Step 1

Wash the fresh tomatoes thoroughly and remove the cores. Cut the tomatoes into quarters.

Step 2

Peel and mince the garlic cloves. Peel and finely chop the yellow onion.

Step 3

In a skillet over medium heat, warm the olive oil. Add the onion and garlic, and sauté for about 3-4 minutes, until fragrant and translucent.

Step 4

Transfer the sautéed onion and garlic to the slow cooker. Add the chopped tomatoes, tomato paste, dried oregano, dried basil, salt, ground black pepper, and sugar (if using). Stir well to combine.

Step 5

Add the bay leaf to the slow cooker and place the lid securely on top.

Step 6

Set the slow cooker to LOW and cook for 7-8 hours, or set to HIGH and cook for 3-4 hours. Stir occasionally if you have time.

Step 7

Once the sauce has finished cooking and the tomatoes have broken down, remove the bay leaf. For a chunkier sauce, leave it as is. For a smoother texture, use an immersion blender directly in the slow cooker to blend the sauce until it reaches your desired consistency.

Step 8

Taste the sauce and adjust seasoning, adding more salt, pepper, or sugar if needed.

Step 9

Serve the sauce immediately over pasta, use as a pizza base, or store in airtight containers in the refrigerator for up to 5 days or in the freezer for up to 3 months.

Step 10

Garnish with fresh basil leaves before serving, if desired.
