How to Make Sauce from Frozen Tomatoes
Ingredients:
- 3 pounds frozen tomatoes (defrosted)
- ¼ cup extra virgin olive oil or butter (or 50/50)
- 2 Tbsp finely chopped garlic (use more or less to your taste)
- ½ cup whole or hand-torn fresh basil (lightly-packed, or 1 Tbsp dried basil)
- ¼ tsp crushed red pepper
- ¼ cup tomato paste
- 1 tsp salt (or to taste)
- ½ tsp black pepper (or to taste)
- ½ tsp dried oregano
Directions:
- Gather and prep all ingredients as mentioned above.
- First, defrost the frozen tomatoes. You can do this on the counter at room temperature or in the refrigerator. Once defrosted, the skins should slip off easily. Remove and discard the skins and cores.
- Hand crush the tomatoes. Be sure to keep the tomato water; it adds great flavor to your sauce. You should end up with about 3-4 cups crushed tomatoes.
- In a heavy-bottomed saucepan or Dutch oven, heat the olive oil or butter over medium-low heat. Add the chopped garlic, basil, and crushed red pepper. Cook for about 5 minutes until the garlic softens.
- Move the garlic mixture to one side of the pot and add the tomato paste. Let it caramelize for 1 to 2 minutes.
- Next, add the crushed tomatoes (with their liquid), salt, black pepper, and dried oregano. Stir everything to combine.
- Increase the heat to medium and bring the mixture to a light simmer. Let it simmer uncovered for about 45 minutes, stirring occasionally, until it thickens to your liking.
- Taste and adjust seasonings if needed. Enjoy your sauce! This recipe makes enough to lightly dress one pound of pasta or can be used in many other dishes. Buon Appetito!
