  • 1 lb ground beef

  • 10 beefstake tomatoes (or 12-13 roma tomatoes)
  • 1/2 onion diced
  • 3 cloves garlic minced
  • 1 tbsp olive oil
  • 1/2 tbsp dried oregano
  • 2 tbsp tomato paste
  • 1 1/2 tbsp fresh basil finely chopped
  • 1/4 tsp sea salt

  • Slice the tomatoes in half, remove the core and quarter. Place in a food processor and pulse a few times, until finely diced and almost pureed.

  • Heat the olive oil in a pot on medium heat and saute the onions for 2-3 minutes or until slightly translucent. Add the garlic and cook an additional minute.
  • Add the tomatoes and oregano to the pot, then stir and simmer uncovered for 20-30 minutes or until the sauce has thickened and much of the liquid has evaporated.
  • While the sauce is cooking, spiralize the zucchini with either a spiralizer or julienne peeler and set aside.
  • Add the ground beef to a saute pan and cook on medium-high heat. Use a wooden spoon or spatula to break the ground beef up into small pieces as it cooks. The beef is done when it's browned and cooked through.
  • After the sauce has reduced, stir in the tomato paste, fresh basil and salt and pepper. Cook for another 2-3 minutes, then add to the cooked ground beef and stir to combine.
  • Add a serving of zucchini noodles to a plate and top with bolognese sauce and grated parmigiano reggiano. Garnish with additional basil.
