Why Choose a Slow Cooker for Tomato Soup?

  • Minimal Cleanup: Everything cooks in one pot.
  • Flexible Timing: Prep in advance and enjoy when ready.

This recipe relies on pantry staples, lets you have dinner ready with little effort, and yields a creamy, flavorful soup that rivals any restaurant offering.

Ingredients

  • 2 cans (28 ounces each) crushed tomatoes
  • 1 tablespoon crushed garlic
  • 1 can (14 ounces) chicken broth or vegetable broth (2 cups)
  • 2 tablespoons granulated sugar
  • 4 tablespoons butter
  • 1 cup heavy cream
  • 1/4 cup fresh basil (or 2 tablespoons dried basil)
  • Salt and black pepper, to taste
  • Optional toppings: parmesan cheese, pesto, croutons

Step-by-Step Preparation Guide

The simplicity of this slow cooker creamy tomato soup recipe cannot be overstated. Here’s how to make it:

  1. Add Tomatoes, Broth, and Garlic

    Combine crushed tomatoes, chicken or vegetable broth, and garlic directly in the slow cooker. Stir well.

  2. Incorporate Sugar and Butter

    Stir in the sugar and divide the butter into small pats, spreading them around the soup mixture.

  3. Slow Cook

    Cover and cook on low for 6-8 hours, or on high for 2-4 hours. If using dried basil, add it now. Fresh basil should be added at the end.

  4. Finish with Cream and Basil

    After cooking, stir the heavy cream into the soup very slowly while continuously mixing. This prevents curdling and ensures a velvety texture. Add fresh basil now if using. Season with salt and black pepper to taste.

  5. Serve and Garnish

    Ladle soup into bowls. Top with parmesan, a dollop of pesto, and croutons if desired. Enjoy hot!

Expert Tips for Tomato Soup Success

  • Choose Quality Tomatoes: Both crushed and diced tomatoes work, but high-quality canned tomatoes yield a richer flavor.
  • Butter Adds Body: Don’t skip the butter—it contributes to creaminess and a luxurious mouthfeel.
  • Fresh Basil: Fold in freshly chopped basil at the end for a burst of flavor and visual appeal.
  • Slowly Apply Cream: Pour the heavy cream in a thin stream with constant stirring. Rapid addition can cause separation or curdling.
  • Customize Consistency: Blend with an immersion blender if you prefer a smoother soup, or leave it slightly chunky for texture.
  • Season Thoughtfully: Taste before serving and adjust seasoning as needed, especially salt and pepper.
