Waste-Free Pasta Sauce

Level of difficulty: WAY EASY!

In fact, I made this pasta sauce in 35 minutes while on a conference call with colleagues. I was able to whip up this yummy sauce AND listen in on the call– so clearly, it is not too difficult. The “recipe” below may frustrate most people. When I cook, I just kind of throw things together. Sometimes I might start with a recipe to get an idea, but I am constantly adapting and improvising. Be easy. Be flexible, and give waste-free pasta sauce a try! Create your own recipe! I’d imagine tomato sauce is pretty hard to mess up (since I didn’t). 🙂

Here is what I used:


  • Some tomatoes (ha! I just piled some in a bag at the store. I think it was about 8-12 Romas)
  • 2 smaller-ish yellow onions (chopped)
  • Some sprouted garlic (chopped)
  • Teaspoon Salt
  • Tablespoon sugar
  • Handful of fresh basil from patio (chopped)
  • Some dried Rosemary, and Parsley
  • Some pepper
  • Olive oil

Here is what I did:

  1. saute garlic and onions in some olive oil
  2. add roughly chopped tomatoes + everything else
  3. brought to a boil and then simmered for 20 minutes, stirring absent-mindedly



4. blended stewy tomatoes in small batches until sauce was smooth











5. poured over some penne and then topped with some left over cheese we hand on hand



6. enjoy with red wine and follow with sleep (I climbed in bed directly after around 7:40PM). Because grad school is hard and you just made F*CKING pasta sauce from scratch. Because the environment! And you deserve it!


7. Don’t forget to put the leftovers in a jar. Because…jars!



  • Simmer 1-2 hours total, instead of 20 minutes.
  • Try different herbs and different varieties of tomatoes.

I used what was on sale– Roma Tomatoes @ $0.69/lb

  • Try adding roasted peppers, when on hand and with extra time
