Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large pot over medium heat, add diced onion, carrot, and celery, and cook for 8 minutes until softened but not browned. Stir in minced garlic and cook for 1 minute until fragrant.
  2. Step 2: Add canned tomatoes (with juices), chicken stock, dried oregano, 1/4 tsp salt, and 1/8 tsp black pepper. Bring to a simmer, then reduce heat to low and cook uncovered for 20 minutes, stirring occasionally. Use an immersion blender to puree until smooth, or transfer to a regular blender in batches.
  3. Step 3: Meanwhile, preheat oven to 375°F. Toss baguette slices with 1 tbsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper. Spread on a baking sheet and bake for 8-10 minutes until golden and crisp. Stir fresh basil into the soup just before serving and top with crispy garlic croutons.
