How to Make Tomato Sauce with Canned Diced Tomatoes
Making a delicious tomato sauce from canned diced tomatoes is one of the easiest and most rewarding culinary experiences. Whether you’re preparing a classic spaghetti dish, a flavorful pizza sauce, or a base for stews and casseroles, utilizing canned diced tomatoes can save time and enhance convenience without sacrificing flavor. Here’s a simple yet effective recipe to guide you through the process.
Ingredients
To create a rich and savory tomato sauce, you will need the following basic ingredients
- 2 cans (14.5 oz each) of diced tomatoes (preferably no salt added) - 2 tablespoons of olive oil - 1 medium onion, finely chopped - 3-4 cloves of garlic, minced - 1 teaspoon of dried oregano - 1 teaspoon of dried basil (or a handful of fresh basil, chopped) - 1 teaspoon of sugar (optional, to balance acidity) - Salt and pepper to taste - Fresh parsley or basil, for garnish (optional)
Instructions
1. Sauté the Aromatics
Begin by heating the olive oil in a large saucepan or skillet over medium heat. Once the oil is hot, add the finely chopped onion. Sauté the onion for about 5 minutes, or until it becomes translucent. This step is crucial as it builds the aromatic base of your sauce. Next, add the minced garlic and sauté for an additional 1-2 minutes, being careful not to let it burn as burnt garlic can impart a bitter taste.
Once the onions and garlic have softened and become fragrant, it’s time to add the canned diced tomatoes. Pour both cans into the pan, including the juices. The natural sweetness of canned tomatoes will deepen the flavor of your sauce.

3. Season the Sauce
After adding the tomatoes, stir in the dried oregano, dried basil, and optional sugar if desired. The sugar will help to counteract any acidity in the canned tomatoes, resulting in a smoother flavor profile. Season with salt and pepper to taste. Remember, you can always adjust the seasoning later, so it's better to start with a modest amount.
4. Simmer to Develop Flavor
Bring the sauce to a gentle simmer. This step is essential as it allows the flavors to meld beautifully. Reduce the heat to low and let the sauce simmer uncovered for 20-30 minutes, stirring occasionally. As the sauce cooks, it will thicken and the flavors will intensify. If you prefer a thicker sauce, you can simmer it longer. Just keep an eye on it and stir frequently to avoid sticking.
5. Final Touches
After simmering, taste the sauce to adjust any seasoning. If you’ve used fresh basil, add it in at this point for a burst of freshness. You can also blend the sauce with an immersion blender for a smoother consistency or leave it chunky, depending on your preference.
6. Serve
Your tomato sauce is now ready to be served! Use it immediately with your favorite pasta, on a pizza, or as a base for a variety of dishes. Alternatively, allow the sauce to cool completely and store it in an airtight container in the refrigerator for up to a week or freeze it for longer storage.
Conclusion
Making tomato sauce from canned diced tomatoes is a straightforward process that yields fantastic results. The versatility of this sauce means that it can adapt to many dishes, making it a staple in any kitchen. Whether you prefer a simple spaghetti dinner or a robust lasagna, this basic tomato sauce can be the foundation of countless meals. So, grab some canned tomatoes and get cooking; the possibilities are endless!
