Roasted Tomato Sauce Recipe | www.homestead-acres.com

We are huge lovers of tomato sauce!  When ever 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 baby sit 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 your using romas 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 then 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!

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.
