Heat a large saucepan or dutch oven over medium heat.
Sauté onions, carrot and garlic over medium heat until onions are translucent, adding a tablespoon of water (or olive oil), as needed, to prevent sticking or burning.
1 sweet yellow onion, 1 carrot, 4-5 cloves garlic
Stir in sliced mushrooms and cook over medium heat about 3-4 minutes.
8 ounces mushrooms
Add crushed tomatoes, basil, oregano, salt, pepper and sugar (if using). Turn heat to medium low and stir every few minutes to prevent it from burning on the bottom.
28 ounces crushed tomatoes, ½ teaspoon dried basil, ¼ teaspoon dried oregano, ½ teaspoon sea salt, ¼ teaspoon black pepper, 2 teaspoons brown sugar
Meanwhile, bring a large stock pot of well-salted water to a boil for the spaghetti. Once the water is boiling, cook the spaghetti according to package instructions.
16 ounces spaghetti
Once the tomatoes are heated through, reduce heat to low and cover loosely with lid, leaving a vent for steam to escape.
Simmer for at least 30 minutes (or up to 60 minutes, if you have the time). Stir every few minutes, to prevent it from burning on the bottom of the pan. Taste and adjust salt, pepper and sugar, as needed.
Combine sauce and spaghetti and serve with fresh basil as garnish!
