2 cups baby portobello mushrooms, roughly chopped
2 cups shiitake mushrooms, roughly chopped
3 celery stalks, roughly chopped
3 medium carrots, roughly chopped
1 yellow onion, roughly chopped
8 cloves garlic
4 cans fire-roasted tomatoes, diced
2 teaspoons dried oregano
1 teaspoon dried basil
1 tablespoon granulated sugar
1 tablespoon olive oil
Kosher salt & freshly ground black pepper
In a food processor, add the chopped baby portobello and shiitake mushrooms. Pulse to combine the two together until finely minced, about the consistency of ground beef.
Place the mushroom mixture in a large pan or skillet.
Add celery, carrots, onion and garlic cloves to the food processor, and pulse until vegetables are combined and finely minced.
Transfer the vegetable mash to the skillet with the mushrooms.
Season the vegetables with a pinch of salt and black pepper.
Add olive oil to the skillet, and place it over medium-high heat. Sauté the vegetables until they start to sweat.
Cover the skillet and reduce heat to medium. Cook the vegetables together until they are fully cooked down, about 20 minutes.
While the vegetables are cooking, add the canned tomatoes to the food processor, and pulse until they are smooth and blended.
Add the puréed tomatoes to the skillet, and stir to combine. Loosely cover the skillet and allow sauce to simmer for 5 minutes.
Add the dried basil, oregano and sugar to the skillet, and stir to combine.
Taste for seasoning and adjust using salt, pepper and sugar.
Serve a large ladle of hot bolognese sauce atop a bowl of al-dente spaghetti, and garnish with fresh basil and/or grated parmesan cheese. Serve immediately.
