This may sound a little over dramatic but this sauce changed my life. It has ruined all other tomato sauces I will ever eat for the rest of eternity. It isn’t something particularly out of the ordinary or over the top. It is just a seriously good and well balanced sauce.

I have to credit most of this recipe to the one and only Thomas Keller. So I guess it shouldn’t surprise you how good this sauce is. And while I humbly admit that there rarley is anything I can do to Mr. Keller’s recipes to improve them, this is one that I have taken some small liberties with to meet my particular preferences.

mirepoix

The sauce starts with roasting veggies. Instead of the standard mirepoix, the key players are fennel bulb, leeks, and yellow onion. Keller uses an even 1:1:1 ratio of the three. I opt for a little heavier on the fennel bulb because I am obsessed with the flavor it brings to this sauce.

If you aren’t intimately familiar with fennel’s flavor profile you probably wouldn’t know that is what you are tasting when devour this sauce. It brings a slightly sweet and very slight anise flavor to the party. And don’t freak out if you think you don’t like anise. I promise it does not over power. I am OBSESSED with the fennel in this sauce. And I think you will love it too!

I make this tomato sauce on Sundays when I will be home for a good chunk of time and then store it for use later in the week if I don’t use it that day. The sauce is so nice because it requires no standing over the stove the man it, it all cooks in the oven, but it does take a few hours to finish.

After the modified mirepoix has roasted for an hour, the tomatoes are added and the sauce continues cooking, reducing, and developing flavors for another hour and a half.

Like I said, this sauce has ruined all other tomato sauces for me. I can’t imagine having spaghetti and meatballs without this sauce. I can’t imagine chicken parmesan without this sauce. I can’t imagine life without this sauce.

Okay, maybe that is too much. But it is pretty darn close to the truth. It is one of those few food items that I crave and salivate over when they are long gone. As much as I love food, those things are few and far between.

Make the sauce.

The end.

  1. sooooo ....I'm gonna make this sauce. :D
  2. This sounds delicious. Do I leave the dutch oven uncovered in the oven?
  3. Lovely post. I'm a reluctant purist with this recipe. I've tried minor changes and been so disappointed with the results, such as using crushed San Marzano tomatoes instead of whole to save a bit of time, or substituting balsamic for the red wine vinegar. I don't hate the results, mind, it's just that I'm too aware of what it isn't and could have been - heaven for as long as it lasts.
