Bring a large pot or dutch-oven to medium heat. Once hot, add avocado oil. Then add onion, carrots and celery and season with salt & pepper. Sauté, stirring occasionally, for about 6 minutes or until the onion is turning translucent and veggies are getting tender.
½ tbsp avocado oil, ½ large yellow onion, 2 carrots, 2 celery stalks, kosher salt & black pepper
Add in the ground beef and use a spatula to break it into small pieces. Continue to cook until the beef is browned. Then, add in the garlic and season with more salt & pepper. Stir, and cook for 1 more minute.
1 lb ground beef, 3 garlic cloves, kosher salt & black pepper
Reduce heat to a simmer. Add tomato paste, crushed tomatoes, beef bone broth, bay leaves, and parmesan rind if using. Stir to incorporate, then cover the pot with a lid and let it simmer for 2 hours - the longer, the better! Every so often, open the lid, stir and make sure it's not bubbling too much - if so, turn down the heat.
2 tbsp tomato paste, 24 oz crushed tomatoes, ½ cup beef bone broth, 2 bay leaves, 1 parmesan rind
After the bolognese has simmered for at least 2 hours, remove the bay leaves and parmesan rind. Then, pour in the heavy cream and milk. Stir to combine and let it warm up. Taste and adjust salt and pepper to your liking.
¼ cup whole milk, ¼ cup heavy cream
After spiralizing your zucchini, heavily salt them and place them onto a paper towel lined plate for at least 10 minutes. This will help draw excess moisture out. Then, ladle some of the bolognese sauce over the zucchini noodles and top with fresh grated parmesan. Enjoy!
