Oven-Roasted Pasta Sauce

The summer sun is still beating down on our little house every day, but on a bookshelf inside rests a stack of brand-new folders, notebooks, and markers. My older son starts kindergarten in two weeks, and despite what the thermometer insists, it’s time for me to acknowledge that the season is almost over.

I feel like I didn’t get much done this summer. Yes, I went to two conferences and gave birth to a very snuggable baby, but in terms of kitchen work? In terms of the ubiquitous “summer fun”? My shelf of empty canning jars are telling me that this summer hasn’t been my most productive, and my blindingly pale legs remind me that I last stepped into a pool in May.

If you couldn’t tell, I am a person who thrives on busy-busy-busy, followed by a do-nothing vacation. A year ago we drove north and spent a week in a riverside cabin, doing not much but fishing and eating s’mores and lounging in the hammock. Now that I work from home, any down time seems just like regular time if I don’t escape these four walls.

My previous summers also featured plenty of “putting up”, getting jars of salsa, diced tomatoes, strawberry jam, and other goodies ready for us to use when even Austin’s long growing season results in nothing but greens and root vegetables. As ambitious as I am, I knew I just couldn’t handle canning pasta sauce this year, at 9 months pregnant.

Luckily, pasta sauce keeps well in the freezer too, and allows for much more flexibility when it comes to the recipe. After a trip to the farmers market and a CSA delivery, I had enough tomatoes for a small batch of sauce. Add some onion, a zucchini, and herbs, and I was ready to go.

Pasta Sauce - A simple pasta sauce to make ahead and store in the freezer.

This oven-roasted pasta sauce really couldn’t be much easier, and it will add a heavenly perfume to your kitchen as it cooks in the oven.

Once it has roasted and cooled, simply puree in a blender or food processor and package into individual containers for the freezer. I like to use freezer bags because they thaw easily as well as stack flat in the freezer, saving lots of space.
