Step-by-Step: How to Make Sheet Pan Soup

Let’s dive into making this delightful soup together. Follow these easy steps, and you’ll be amazed at how simple it is!

Ingredients You’ll Need:

  • 1 head of garlic
  • 3 red bell peppers, halved and deseeded
  • 10 oz carrots (about 5 large carrots), cut into 1-inch pieces
  • 1/2 of a small head of cauliflower, roughly chopped
  • 3 small tomatoes, quartered
  • 1 small yellow onion, cut into wedges
  • 2 tablespoons olive oil
  • 1 1/2 teaspoon kosher salt, divided
  • 1 teaspoon smoked paprika
  • 1/8 teaspoon cayenne
  • 1/4 teaspoon cumin
  • 2 1/2 cups chicken or vegetable broth
  • Juice from 1 lemon (~2 tbsp)
  • 2 slices of bread (we used sourdough)
  • 2-3 slices cheddar or American cheese
  • 1-2 tablespoons butter

Directions: Cooking with Confidence

  1. Preheat your oven to 400˚F.
  2. Prepare the garlic: Slice off the top of the head to expose the cloves. You’ll only need half for the soup, but roasting the whole head means you can save the extra for another dish!
  3. Roast the vegetables: Place the bell peppers (skin side up), carrots, cauliflower, tomatoes, garlic, and onion on a large sheet pan. Drizzle with olive oil and sprinkle with 1 teaspoon of salt, smoked paprika, cayenne, and cumin. Roast for 40-45 minutes, until all the vegetables are fork-tender.
  4. Heat the broth: About 10 minutes before the vegetables are done, warm the broth in a small pan over medium heat or pop it in the microwave until hot.
  5. Blend it all together: Once the vegetables are tender, transfer them to a blender. Squeeze the roasted garlic cloves from half of the head (keep the other half for another recipe). Add the hot broth and lemon juice, then blend until smooth. Taste and adjust with the remaining 1/2 teaspoon of salt if needed.
  6. Serve hot: Pair your soup with grilled cheese or make grilled cheese croutons to take it to the next level!
  7. Make grilled cheese croutons: Add butter to a pan over medium-low heat. Toast the bread until golden brown and caramelized, flip one slice to add cheese, then top it with the other piece. Cover with a lid and cook until the cheese melts and both sides are crispy. Slice into small cubes.

How to Serve Sheet Pan Soup and Make It Shine

Serve your Sheet Pan Soup hot in a cozy bowl, topped with those delicious grilled cheese croutons. The crunch of the croutons contrasts beautifully with the smooth soup, creating a delightful textural experience. Enjoy every bite with a warm smile.

How to Store Sheet Pan Soup for Later

If you have leftovers (which is unlikely, because it’s that good!), store them in an airtight container in the fridge for up to 3 days. Reheat on the stove or in the microwave, adding a splash of water if it thickens too much.

Clara’s Tips for Success

  • Don’t rush the roasting: The longer you roast the vegetables, the sweeter and more flavorful they become.
  • Experiment with spices: Feel free to adjust the spices based on your taste. Love a bit more heat? Add a pinch more cayenne!
  • Add greens: Spinach or kale can be added to the blender for extra nutrition.

Simple Variations to Try

  • Herby twist: Add fresh herbs like basil, parsley, or thyme after blending for a fresh flavor boost.
  • Creamy touch: Stir in a splash of cream or coconut milk after blending for rich creaminess.
  • Protein-packed: Add cooked chicken or beans before blending for a heartier meal.
