Here is a really easy but very tasty marinara sauce which is particularly good when you have extra tomatoes. But even at this time of year with store bought tomatoes, it makes a good sauce. Cut up a bunch of tomatoes. You can combine different varieties of tomatoes or use just one kind. Whatever you prefer! Place them on a cookie sheet. Sprinkle them with oregano, salt & pepper and thyme. Drizzle olive oil over them and place in a 300 degree oven.
Chop up 4 large onions and slice the tops off of 5 heads of garlic. Scatter the onions over a cookie sheet and place the garlic head side up. Sprinkle with the same combination as the tomatoes and drizzle with olive oil. Place these in a 300 degree oven as well.
After a couple hours of baking, place them under the broiler until singed.
Dump them all in a big pot.
Make sure to scrape up all the brown bits and oil from the cookies sheets. In a separate bowl, squeeze out all of the cooked garlic cloves.
Add the onions to the tomatoes.
Using an immersion blender, blend to a smooth puree.
Add the baked garlic cloves and continue to blend until smooth. I also added a small can of tomato paste to the sauce. Place back in a 300 degree oven and cook one hour longer.
This sauce does not have a strong garlic flavor since the garlic was baked. It has a very rich caramelized garlic flavor.
