Instructions

In a large pot, heat 2 tablespoons olive oil and 2 tablespoons unsalted butter over medium-high heat. Add diced carrots and onions, cooking for 8 to 10 minutes, until completely soft.

Add garlic and cook for about 1 minute, until fragrant.

Drizzle in balsamic vinegar. Pour in fire-roasted diced tomatoes and their juices, along with vegetable broth, dried thyme, salt and red pepper flakes. Stir to combine and bring to a simmer. Cook for about 20 minutes, until the carrots are completely tender.

Stir in fresh basil. Use an immersion blender to blend until smooth, or transfer the soup to a blender and blend until smooth.

Once soup is smooth, stir in whole milk and warm until heated through.

Serve with crispy croutons, fresh basil and a drizzle of olive oil.

Tips & Tricks (5)

Roasting Technique Magic 🔥
Roast tomatoes, onions, and carrots at 425°F for 25-30 minutes to develop deep caramelization and intensify their natural sweetness before blending.
Blending Brilliance 🥣
Use an immersion blender or work in batches with a standard blender, always removing the center lid cap and covering with a towel to prevent hot soup explosions.
Balsamic Balance 💧
Add balsamic vinegar in small increments and taste as you go - its acidity should brighten the soup without overwhelming the roasted vegetable flavors.
Milk Tempering Trick 🥛
Slowly whisk whole milk into the soup off the heat to prevent curdling and ensure a silky, smooth texture.
Herb Infusion Technique 🌿
Chiffonade the fresh basil by stacking leaves, rolling tightly, and slicing thinly to release maximum aromatic oils when garnishing the soup.
