Ingredients
- 8 large tomatoes or 16 Roma tomatoes
- 2 small sweet peppers or 1 red bell pepper if you prefer
- 1/4 cup chopped onion or 6 green onions (just the white part)
- 3 cloves fresh garlic, peeled
- Fresh basil, chopped, to taste
- Fresh parsley, chopped, to taste
- 2 dried bay leaves
- 1-2 tbsp corn starch
Instructions
- Place chopped tomatoes, peppers, onion, and garlic in a blender, and pulse to desired consistency.
- If you like a chunky sauce, do not blend one of the tomatoes, and just finely hand-dice that one instead.
- Pour tomato mixture into a slow cooker, and the diced tomatoes if you are using them.
- Add chopped basil and parsley, stir, then add in the 2 bay leaves.
- Cover and simmer on low for 4-6 hours.
- If you find that your sauce is too thin after simmering (it will depend on how juicy your tomatoes are), simply make a thick paste with some corn starch and water and mix it into the sauce, allowing a little time to thicken before serving.
Notes
Home Chef Tip: To reduce the acid in any tomato-based sauce, add a quarter of a can of light beer while cooking.
