Summer is upon us and so are fresh vegetables from the garden! I’m working on getting my vegetable garden up and running, but thankfully I have a lot of sweet friends who like to gift me their surplus of produce! Tomatoes are no exception, and the best way to use a lot of fresh tomatoes is to make a sauce!
I’m calling this simple roasted tomato sauce blog post a recipe, but honestly we (my 8 year old and I) threw this together without any cookbook or measurements at all. If you’re the type that likes exact measurements, I will link the recipe that our sauce is loosely based on, here. We would just estimate the amount of ingredients we think we needed, whether an ounce or teaspoon haha
The taste of fresh, roasted tomatoes is heavenly, but the nutrition is the most important part; tomatoes are a great source of fiber and are low in calories, sodium and carbohydrates.


This tomato sauce recipe is not designed for canning. We simply poured ours in a ball jar airtight container and plan to use it within the week stored in the refrigerator. In fact we had so much of it that I froze half of it in a freezer bag to thaw and use for later!
Ingredients we used –
What kind and how many tomatoes?
We filled two large sheet trays with a variety of tomatoes, we even included cherry tomatoes which really helped to sweeten our sauce. We prefer the natural sweetness of fresh tomatoes to canned tomatoes.

If you watch the video above, you’ll see that we added ingredients to our liking. If you love onion and garlic, you can definitely add more! The same goes with fresh basil, salt and pepper. You can also add your favorite herbs to this sauce, such as oregano, thyme or parsley. If you’re feeling really brave and want to spice things up, add a pinch of red pepper flakes!
The great thing about this sauce is that you can always add more seasonings once you plan on using it. I’ll probably use it for pasta, and when I reheat it on the stove I will taste it again to see if there’s anything else I’d like to include!
Steps to Simple Roasted Tomato Sauce
Wash and Dry Your Tomatoes
We first wash and rinse all of our tomatoes before we chop them. It’s important to pat dry your tomatoes after washing them so that they develop that beautiful caramelization as they roast in the oven.

Cut Your Tomatoes If Needed
For the larger slicing tomatoes, we chopped them into wedges. But for the smaller size cherry tomatoes, we simply left them whole! You can crush tomatoes as well if you’d prefer that to chopping. Then we laid them all out onto two large sheet trays.


Add Your Seasonings
We used one small onion for both trays, about 3 tablespoons of fresh garlic from garlic cloves, and then sprinkled the tomatoes liberally with basil, salt and pepper. Then we finished them off with a heavy drizzle of olive oil!

Roast Your Tomatoes
We roasted our tomatoes at 425 for about 35 minutes, or until your tomatoes and onions start to caramelize and turn brown. They will look delicious enough to eat them right off the pan!



Blend and Store
I used a slotted spatula to remove the tomatoes, onions and garlic from the tray so that most of the juices were left behind. If you like a thinner sauce, you could definitely include the tomato juice!
Then we blended ours with an immersion blender and poured the fresh tomato sauce into a quart sized ball jar. I could not believe how much sauce just one tray of tomatoes gave us! Don’t forget you an freeze the sauce and use it later!


Sweeten Your Simple Roasted Tomato Sauce if Desired
Our sauce was honestly delicious as is, but I like a little sweetness to balance out the acidity. Rather than using refined sugar, we chose to add some raw honey! It sweetened the sauce perfectly and added so much flavor.
A perfect way to use this tomato sauce would be with spaghetti and meatballs! Just let the sauce simmer in at medium heat in a large pot and stir occasionally with your favorite wooden spoon. Add some noodles and parmesan and you’ve got a delicious, protein rich homemade meal!

I hope you enjoyed this simple roasted tomato sauce recipe! Truth be told, my 8 year old did most of the work! We can’t wait to use this sauce in our spaghetti tonight!

I worked in a tearoom and the owner made this every year when the garden was packed with tomatoes. We’d pile the roasted tomatoes on toasted Italian bread for lunch and we’d use it as a base for tomato soup. Thanks for posting this.
