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 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. 

This tomato sauce recipe is not designed for canning. We simply poured ours in a ball jar and plan to use it within the week. In fact we had so much of it that I froze half of it in a freezer bag to use for later! 

Ingredients we used – 

• Fresh tomatoes
• Onion
• Minced garlic 
• Basil 
• Salt
• Pepper
• Olive Oil
• Honey 

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. 

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 basil, salt and pepper. 

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

It’s important to pat dry your tomatoes 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! 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 garlic, 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. 

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! 

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. 

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!
