Oven-Roasted Fresh Tomato Sauce Recipe

Oven-Roasted Fresh Tomato Sauce is a perfect and delicious idea to use those last of the season fresh vine-ripened tomatoes.  This is not really a recipe, but more of a technique that I use for making this wonderful Oven-Roasted Fresh Tomato Sauce.  This is a very simple technique that is subject to endless variation to your taste.  My new favorite way to use up summer tomatoes!

This outstanding sauce can be used to top your pasta dishes, pizza topping, lasagna, tomato soup, or whatever else you can think of.  Be creative in making and using this tomato sauce.

Oven-Roasted Fresh Tomato Sauce Recipe:


Prep Time: 30 minutes

Cook Time: 1 hour, 30 minutes

Yield: makes a large batch


Fresh vine-ripened tomatoes
Garlic cloves, minced
Chile peppers
Fresh herbs of your choice (such as basil, rosemary, oregano, thyme)*
1/4 to 1/2 cup extra-virgin olive oil
Coarse salt and freshly-ground black pepper
Granulated sugar (optional)**

NOTE:  I can not give you exact measurements for this recipe, because I just do it!  Don't be afraid of messing up, because you can't!

*  I like to use fresh basil leaves.

**  I find that adding a little sugar to tomato sauce after the sauce is cooked, but still hot, cuts some of the acid and mellow the flavor.  You do not want to add too much, so start with approximately 1/2 teaspoon per quart.  When making spaghetti sauce, I add molasses instead of sugar.



Preheat oven to 350 degrees F.  Place oven rack in the center of the oven.

Prepare Vegetables:

Tomatoes:  Wash tomatoes and cut out the stem core.  Slice the tomatoes in half lengthwise and then into quarters

Garlic:  Remove the papery skin from the whole garlic cloves. Either mince or chop.

Chile Peppers:  Remove stems from chile peppers, cut in halves, and remove seeds.

Onions:  Remove skins from onions and quarter. Cut into quarters or fourths.

Herbs:  Strip the fresh herbs off their stem.

Place prepared tomatoes, garlic cloves, chile peppers, and herbs in a large roasting pan.  Add olive oil and stir to combine.  Do not add any more liquid as the natural juices from the tomatoes will provide all the liquid that you need (and sometimes more than you need).

Bake approximately 1 1/2 to 2 hours, stirring every 30 minutes.

Let the tomato mixture cool slightly before straining.  Use a large strainer or a food mill to remove the skins, seeds, and herbs.  The resulting puree will be nice and thick.  Season to taste with salt and pepper.

If you end up with more liquid than you want (this happens when you use regular garden tomatoes and not Roma tomatoes), simmer the mixture over low heat until reduced to the thickness you want.  This is what I had to do this time because I used end-of-the-season large very ripe garden tomatoes. As I was left with too much liquid, I then put the pot back on the burner and simmered the sauce until it achieved the thickness I wanted.

Either refrigerate and use within 5 days or freeze.  I find that I like to freeze the sauce in small amounts at a time.  You may only need to use a little at a time, depending on your recipe.  Vacuum sealed bags and small freezer containers work well.

Makes a large batch.


Variation Idea:  

Add 1 (2-ounce) can of anchovies, packed in oil.  You do not taste the anchovies , but the anchovies add a rich, savory, and salty layer to the sauce.  Excellent served over pasta of your choice.

After I roasted the vegetables for about 1 1/2 hours, I blended everything in my Vitamix.  I had used about five fresh Roma tomatoes and a couple of others, plus an onion, red pepper, 5 garlic cloves, and some fresh basil.  I added some water when I blended it.  I cooked some chicken strips separately and then added some of the sauce.  Delicious – thanks!! – Marcia Brumbaugh (10/9/14)
