Ingredients

• 2 lbs tomatoes
• 1 medium onion
• 1 carrot
• 2 stalks celery
• 1/4 tsp saffron threads
• 2 cups chicken stock
• 1/4 cup heavy cream
• 1 slice baguette
• 2 tbsp olive oil
• 1 tsp fresh thyme

Instructions

1. Step 1: Chop tomatoes (cored), onion, carrot (diced), and celery (minced) into uniform 1/4-inch pieces. Heat 1 tbsp olive oil in a heavy pot over medium heat. Add vegetables and cook 8 minutes until softened and onions are translucent.
2. Step 2: Stir in saffron threads and cook 1 minute until fragrant. Add chicken stock and bring to a gentle simmer. Cover and cook 15 minutes to meld flavors.
3. Step 3: Use an immersion blender to puree soup until completely smooth. Stir in heavy cream and simmer uncovered for 5 minutes until slightly thickened (soup should coat the back of a spoon).
4. Step 4: While soup simmers, cut baguette into 1/2-inch cubes. Toss with 1 tbsp olive oil, 1 tsp fresh thyme, and a pinch of salt. Bake on a sheet pan at 375°F for 8 minutes until golden and crisp.
