Ingredients
  

  • 2 28-ounce cans of crushed tomatoes
  • 1 medium onion finely chopped
  • 3-4 cloves garlic minced
  • 4 cups vegetable or chicken broth
  • 1 cup heavy cream
  • 1 cup grated Parmesan cheese
  • 2 tbsp olive oil
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1 tsp sugar
  • salt and pepper to taste
  • fresh basil chopped, optional for garnish

Instructions
 

  • In a skillet, heat the olive oil over medium heat and sauté the chopped onion until translucent, about 5 minutes. Add the minced garlic and cook for another 1-2 minutes until fragrant.
  • Transfer the sautéed onions and garlic to your slow cooker. Add the crushed tomatoes, vegetable or chicken broth, dried oregano, dried basil, and sugar.
  • Stir everything together until well combined. Cover and cook on low for 6-8 hours or on high for 3-4 hours.
  • About 30 minutes before serving, use an immersion blender to purée the soup until smooth. If you prefer a chunkier texture, you can purée only half of it.
  • Stir in the heavy cream and grated Parmesan cheese. Continue to cook for another 15-20 minutes until the cheese has melted and the soup is heated through.
  • Taste and adjust seasoning with salt and pepper as needed.
  • Serve hot, garnished with chopped fresh basil if desired.

Notes

For extra richness, add a splash of white wine before slow cooking or serve with a grilled cheese sandwich on the side.
