Cuisine: Italian
Serves: 4 servings
Ingredients
- 2 lbs ripe tomatoes, halved
- 1 onion, chopped
- 2 cloves garlic, minced
- 2 cups vegetable broth
- 1 teaspoon dried basil
- Salt and pepper to taste
- 1 tablespoon olive oil
Instructions
- Prepare the vegetables by washing the ripe tomatoes thoroughly and cutting them in half. Remove any stems or blemishes.
- Peel and chop the onion into medium-sized pieces. Mince the garlic cloves finely to release their aromatic flavors.
- Drizzle olive oil into the slow cooker, ensuring the bottom is lightly coated to prevent sticking.
- Place the halved tomatoes cut-side up in the slow cooker, arranging them in a single layer for even roasting.
- Sprinkle the chopped onions and minced garlic evenly over the tomatoes.
- Season with dried basil, salt, and freshly ground black pepper to enhance the tomatoes' natural sweetness.
- Pour the vegetable broth carefully around the tomatoes, ensuring not to disturb their arrangement.
- Cover the slow cooker and set to low heat. Cook for 6 hours, allowing the tomatoes to slowly roast and develop deep, rich flavors.
- After cooking, use an immersion blender to puree the soup directly in the slow cooker until smooth and creamy.
- Taste and adjust seasoning if needed, adding more salt, pepper, or basil to suit your preference.
- Ladle the hot soup into serving bowls. Optional: garnish with fresh basil leaves or a drizzle of olive oil before serving.
Tips
- Choose ripe, in-season tomatoes for the most intense flavor. The ripeness directly impacts the soup's depth and sweetness.
- Don't rush the cooking process. The 6-hour slow cook allows the tomatoes to caramelize and develop complex flavors that can't be achieved through quick cooking.
- For extra creaminess, consider adding a splash of heavy cream or a dollop of crème fraîche when blending.
- If you prefer a smoother consistency, strain the soup through a fine-mesh sieve after blending to remove any remaining seeds or skin.
- Experiment with garnishes like crispy basil leaves, a swirl of pesto, or homemade croutons to elevate the presentation and texture.
