Ingredients and substitutes
- Tomatoes – I love picking red ripe but still firm tomatoes. They cook down beautifully. You can even roast the tomatoes in the oven at 160°C for an hour to get a nice, roasted, smoky flavor for the sauce. If you like cherry tomatoes, you’ll love my recipe: Cherry Tomato, Olive, and Basil Pasta.
- Garlic – I think you absolutely need garlic, and it’s just a small amount, but it adds so much flavor. If you like roasted garlic, save a few for your tomato sauce. It adds a lovely, sweet, garlicky flavor.
- Bay leaves – Add an earthy flavor, but if you don’t fancy them, you can just leave them out.
- Thyme and Oregano – I love fresh herbs, but I don’t always have them fresh on hand. If you do, that’s great! By all means, fresh is the way to go.
- Brown Sugar – The main purpose of the brown sugar here is to caramelize it, adding a touch of brown to the red. Do you know what happens when you add a touch of brown to red? It deepens the red. We are using the same principle here. Just adding a dash of brown to the red, so make sure to just caramelize, not burn it.
Step-by-step: Fresh tomato sauce
- Sauté – Add oil and garlic into a large pot or Dutch oven. With the heat on low, let the garlic infuse into the oil for a minute, making sure not to brown or burn it. Once the garlic is fragrant, add the dried herbs. Followed by the diced onions and bay leaves. Sauté for 2 minutes more.
- Sugar – Gently move the onions to one side of the pan, keeping the center near the heat clear. Add in the brown sugar. Let it caramelize slowly so it browns, not burns. This will add a little brown color that will intensify the sauce’s color.
- Tomatoes – Now, mix in the onions again and continue cooking. Next, add the chopped tomatoes and tomato paste. Season with salt and pepper to taste.
- Simmer – Cover the pan, lower the heat to a simmer, and let it simmer gently for 15 minutes. After 15 minutes, you should have a thick, dark tomato sauce.
- Garnish – Add in your fresh basil leaves. You can leave the sauce chunky or use a hand blender to blend it to a smooth paste.
- Serve over fresh pasta or use as a base for other tomato sauce variations.
Tips for making fresh tomato sauce
- Always use ripe, fresh tomatoes for the best flavor.
- Don’t skip caramelizing the sugar — it deepens color and taste.
- A Dutch oven or heavy-bottomed pot works best for simmering.
- If the sauce is too watery, simmer it uncovered until it reduces.
- Adjust acidity with a pinch of sugar or a splash of balsamic if needed.
- Store in small freezer-safe portions for easy pasta nights.

Frequently asked questions

Both are tomato sauces. However, marinara sauce is best made with crushed and strained San Marzano or plum tomatoes. Since I’m using regular seasonal tomatoes, I prefer to call this a fresh tomato sauce.
The base is the same. However, a pasta sauce is usually simmered over low heat until it is thicker. The slow cooking makes the tomatoes sweeter, richer, and deeper in flavor.

thank you for all the info
Do I need to peel the tomatoes or is it ok to leave the skins on?
Hey Christi. I like a rustic tomato sauce so I do leave the skin on. But you can certainly take it one step further and skin the tomatoes (blanchiing them for a minute in hot water should do the trick)
A good tomato sauce is very important in cooking. I tried your recipe and I fell in love with it. Use it every time I am cooking a tomato based dish.
Absolutely, Thanks Adriana
Everyone in my family loves this! Delicious!!
Thank you so much, Cynthia.
Excellent sauce. Used my fresh Roma tomatoes and the taste and sauce also using my fresh onions and basil sent this sauce over the edge. I have tons of tomatoes so working on my second batch and will probably be doing it again another 2 times to end up with 4 batches. I used my food Saver and froze flat for stacking. I look forward to walking to the freezer this fall and winter for sure.
Wow, Diane. So lucky you have so many fresh homegrown tomatoes. Thank you so much for coming back to write this feedback. So happy you are enjoying this recipe. It sure is our family favorite. Have a great day
