Roasted Tomato Sauce: This is the only tomato sauce I ever make! Learn how to make this easy homemade tomato sauce that you can use in all your tomato dishes! Perfect for freezing and canning too.

We are huge lovers of tomato sauce!  Whenever I can find a good price on tomatoes or our garden is overflowing with ripe tomatoes I love making our own sauce.

It is a lot of work to prep it all and let it simmer on the stove all day.  So recently I decided to try roasting our tomato sauce in the oven instead of simmering on the stove top.  We are hooked!

The sauce tastes so much better roasted and it saves me a lot of time as well.  This recipe takes just a few minutes to put together and once it’s in the oven I don’t have to babysit it.

Now one thing to remember both hubby and I are a dash of this and a little of that type of cooks.  We do NOT often measure spices etc. in our recipes.

I’ve done the best I can to estimate the amounts of salt and spices we use when we make this sauce.  Feel free of course to adjust them to suit YOUR family’s tastes.

Cut tomatoes, onions, garlic and herbs ready to roast

Wash the tomatoes and cut the stem ends off.  If the tomatoes are large slicing tomatoes cut them into quarters and place in a roasting pan.

If you’re using roma tomatoes then cut them in half, if you have cherry tomatoes to use up just add them in whole!  Add a quartered large onion, 7 to 8 cloves of garlic, fresh basil, dried oregano, rosemary, salt, sugar, pepper and lemon juice to the roaster.

Place in your oven and roast for 1 1/2 to 2 hours.  I find roma tomatoes cook a little faster than the beefsteak type.

Now be prepared to be driven crazy by the amazing smell in your kitchen!  When I cook this we can smell it all the way outside.  It’s sooooo good!

Puree the tomato sauce |

When it’s finished cooking, remove it from the oven and let it cool slightly.  Then ladle it into a blender and puree until it’s a consistency that you like.

It doesn’t take long everything is cooked nice and soft.  Pour the sauce into another pot to keep warm.

Now it’s ready to freeze, can or eat for supper!  I hope you enjoy this recipe as much as our family does.

Hi, Kim, I was wondering if you have the amount of time to process the tomato sauce in a hot water bath, or do you think it needs to be pressure canned and, if so, for how long and at what number pounds? I made something similar last gardening season and froze it (it was AMAZING), but one of my grandchildren left the freezer door open in our outside fridge and I wound up tossing it all just to make sure it wasn’t contaminated. I’m looking forward to making more this year and canning it so that doesn’t happen again!! Thank you for your answer in advance!

I’m assuming this cooks in the oven uncovered? Thanks
