Ingredients
  

  • 2 tablespoons butter or olive oil
  • 1 small yellow onion, diced
  • 3 cloves garlic, minced
  • 2 (14.5-ounce) cans diced tomatoes, preferably fire-roasted
  • 1 cup low-sodium chicken or vegetable broth
  • ½ cup heavy cream
  • 3 ounces cream cheese, softened and cubed
  • ½ teaspoon dried oregano
  • ¼ teaspoon red pepper flakes (optional, for a gentle kick)
  • 1 teaspoon sea salt, more to taste
  • ½ teaspoon freshly ground black pepper
  • ½ cup fresh basil leaves, loosely packed, plus extra for garnish
  • 1 handful Freshly grated Parmesan, for serving (optional)

Instructions
 

  • Sauté the aromatics: Heat butter or olive oil in a medium pot over medium heat. Add the diced onion and cook 4–5 minutes, until softened and translucent. Stir in the garlic and cook 30 seconds, just until fragrant.
    2 tablespoons butter or olive oil, 1 small yellow onion, diced, 3 cloves garlic, minced
  • Add tomatoes and seasoning: Pour in the diced tomatoes with their juices and the broth. Stir in oregano, red pepper flakes (if using), salt, and pepper. Bring to a gentle simmer.
    2 (14.5-ounce) cans diced tomatoes, preferably fire-roasted, 1 cup low-sodium chicken or vegetable broth, 1/2 teaspoon dried oregano, 1/4 teaspoon red pepper flakes (optional, for a gentle kick), 1 teaspoon sea salt, more to taste, 1/2 teaspoon freshly ground black pepper
  • Simmer to meld flavors: Let the soup simmer uncovered for 10–12 minutes, stirring occasionally. This reduces some liquid and concentrates the tomato flavor.
  • Blend until smooth: Turn off the heat. Add the fresh basil leaves. Use an immersion blender to blend the soup right in the pot until silky. If using a countertop blender, carefully blend in batches and return to the pot.

  • Make it creamy: Return the pot to low heat. Add the cream cheese and whisk until it melts and fully incorporates. Stir in the heavy cream.
    3 ounces cream cheese, softened and cubed, 1/2 cup heavy cream
  • Balance the acidity: Taste the soup. If it’s too tangy, stir in 1–2 teaspoons of keto-friendly sweetener until balanced. Adjust salt and pepper as needed.
  • Serve: Ladle into bowls and garnish with extra basil and Parmesan if you like. Serve hot.
    1 handful Freshly grated Parmesan, for serving (optional)
