1-Heat olive oil in a medium-sized skillet: Heat olive oil in a medium-sized skillet over medium heat. Add diced onion and caramelize until lightly golden brown (about 9-10 minutes) stirring occasionally. Add minced garlic and thyme and saute 1-2 minutes.

Season to taste with salt and pepper (I always add a pinch of black pepper and typically a pinch of salt when I use unsalted broth).
3-Enjoy this pasta over your noodles or: Enjoy this pasta over your noodles or vegetable “noodles” of choice! I find this to be the perfect amount of sauce for 16 ounces of pasta, but use as much or as little as you prefer. The sauce freezes well, so you can freeze half for another meal later.
