Ingredients

  • 2 TBSP olive oil
  • 3 cloves of garlic, minced
  • 1/2 white onion, diced
  • Kosher salt and cracked black pepper, to taste Start with 1/4 tsp and work your way up as needed. This is a personal preference, so season to taste.
  • 1/4 cup chopped fresh parsley
  • 1 TBSP tomato paste
  • 8 oz mushrooms, sliced or diced I like to use Baby Bella when I can find them, but any mushrooms will do.
  • 28 oz can of whole peeled tomatoes; don't drain
  • 28 oz can of puréed tomatoes
  • 1 tsp sugar
  • 1/4 tsp baking soda
  • 1 TBSP butter (optional)

Instructions

  • Heat 1 TBSP of olive oil in a large saucepan or Dutch oven over medium-low heat. Once the oil is hot, add the garlic and onions. Cook them, stirring every now and then to prevent the garlic from burning, for about 3-5 minutes, or until the onions are tender. Increase the heat to medium heat. Add a bit of salt and cracked black pepper.
  • Add the fresh parsley and the tomato paste to the onions, and stir until the onions are pretty much coated with the paste.
  • Add the mushrooms to the onions and, if needed, add the other TBSP of olive oil. Stir to coat and cook for about 5-7 minutes, or until the mushrooms are tender.
  • Once the mushrooms are tender, add the tomatoes (don't drain them; include the juice), the tomato purée, and the sugar. Stir the contents of the pot, and partially cover the saucepan or Dutch oven with a lid. Decrease the heat to medium-low and let the sauce simmer for 30 minutes to an hour.
  • After you've let the sauce simmer for a while, come back, and give it a taste. This is where you're going to have to make your own decisions based on your own personal preference. If you find the sauce to be acidic (which I always do at this point), add the baking soda. The sauce will foam and fizz. Give it a good stir and let it simmer for about 15 minutes before tasting it again. Once some time has passed, taste it and adjust your seasoning (salt + sugar). Your sauce should be much less acidic, but if this definitely depends on the tomatoes you're using. If it's still too acidic, add more baking soda in 1/8 tsp increments until it's just right, but it shouldn't take more than one more pinch of the stuff.
  • Let the sauce simmer for 3-4 hours, partially covered with a lid. Come back to stir it occasionally and, of course, give it a taste. The longer your let your sauce simmer, the more flavorful it will get.
  • When it's time to remove the sauce from the heat, add a knob of butter (about a TBSP) to the sauce and stir. This will leave you with a super creamy and super smooth finish.
  • Toss this sauce with your favorite pasta, layer it in with your lasagna, or slather it over a pizza shell!

Notes

Tip: If you keep Parmesan or Romano rinds in your freezer like I do, throw one of them into this sauce before you let it simmer for hours. It gives off a wonderful flavor and nice, smooth texture.
