How to Make Super Green Sheet Pan Soup with Pesto-Grilled Cheese Croutons Recipe
Step 1: Roast the Vegetables
Start by preheating your oven to 400˚F to get things nice and hot. Slice off the top of the garlic head, exposing all those beautiful cloves. Spread out the leeks, cauliflower, broccoli, zucchini, potatoes, and that exposed garlic on a large sheet pan. Drizzle everything generously with olive oil, sprinkle 1 teaspoon kosher salt and black pepper on top, then toss gently to coat the vegetables evenly. Roasting these allows the flavors to deepen beautifully with caramelized edges and tender centers. Roast the veggies for about 30 minutes until fork-tender, filling your kitchen with an irresistible aroma.
Step 2: Warm the Broth and Peas
Once the vegetables are nearly done, about 10 minutes before the sheet pan finishes, place the broth and frozen peas in a saucepan and heat them until they are gently simmering. This ensures the soup base is hot and ready for blending, which helps achieve a smooth, even texture in the final soup.
Step 3: Blend Soup Ingredients
Carefully add half of the roasted garlic cloves along with all the other roasted vegetables into a blender. Pour in the hot broth and peas, then squeeze in the fresh lemon juice for brightness. Toss in the spinach and fresh parsley, sprinkle with the remaining salt to taste, and add a pinch of red pepper flakes if you love a hint of spicy warmth. Blend everything until silky smooth. The result is a luscious, vibrant green soup that tastes like sunshine in a bowl, comforting yet fresh and light.
Step 4: Make Pesto-Grilled Cheese Croutons
Turn your attention to the croutons that truly make this dish special. Melt butter in a skillet over medium-low heat. Toast one slice of bread until golden brown and caramelized on one side, then flip it over and start layering: add two slices of pepper jack cheese, spread pesto on top of the melted cheese, then cover with the remaining two cheese slices. Placing cheese in this clever double-decker way keeps the bread from getting soggy beneath the pesto. Top it with your second slice of bread, cooked side down. Cover with a lid to melt the cheese thoroughly while keeping the bread perfectly crispy. Flip once more to brown the other side, ensuring every part is crisp and oozy-cheesy. Once done, slice the sandwich into small cubes to create irresistible pesto-grilled cheese croutons.

Freezing
This soup freezes beautifully, so if you want to save time for busy days, pour it into freezer-safe containers or bags. The soup will stay good for up to 3 months. Note that the pesto-grilled cheese croutons are best made fresh, as they can lose crispness after freezing and reheating.
Reheating

FAQs
Can I make this soup vegan?
Absolutely! Use vegetable broth and swap butter for olive oil in the grilled cheese croutons, and replace the cheese with your favorite vegan cheese to keep it plant-based and delicious.
What other breads work well for the grilled cheese croutons?

Definitely! Kale, swiss chard, or even arugula can be wonderful additions that amp up the nutrition and flavor complexity of your soup.

- 3 tbsp fresh parsley
- Optional: 1/4 tsp red pepper flakes
Grilled Cheese Croutons
- 1–2 tbsp butter
- 2 slices sourdough bread
- 4 slices pepper jack cheese
- 2 tbsp pesto
Instructions
- Prepare and roast vegetables: Preheat your oven to 400˚F (205˚C). Slice off the top of the head of garlic to expose the cloves. Arrange the leeks, cauliflower, broccoli, zucchini, potatoes, and garlic head on a large sheet pan. Drizzle with olive oil, sprinkle with 1 teaspoon of kosher salt and black pepper, and toss gently to coat everything evenly. Roast in the oven for 30 minutes until all the vegetables become fork-tender.
- Heat broth and peas: About 10 minutes before the vegetables finish roasting, add the chicken or vegetable broth and frozen peas to a small pot. Warm over medium heat until it reaches a gentle simmer.
- Blend the soup: Remove the roasted vegetables from the oven. Using only half of the roasted garlic cloves squeezed out from the head, add those along with all the roasted vegetables to a blender. Pour in the hot broth and peas mixture, fresh lemon juice, spinach, parsley, the remaining 1/2 to 1 teaspoon of kosher salt (adjust to taste), and the optional red pepper flakes. Blend until the soup is smooth and creamy.
- Make grilled cheese croutons: In a pan over medium-low heat, melt the butter. Toast one slice of sourdough bread in the pan until the bottom is golden brown and caramelized. Flip it over, then layer 2 slices of pepper jack cheese on the caramelized side. Spread pesto over the cheese, then top with the remaining 2 cheese slices to prevent sogginess. Place the second slice of bread, cooked side down, on top of the cheese. Cover with a lid and cook until the bottom slice is brown and crispy. Flip again and cook until the other side is golden and the cheese is fully melted. Remove from the pan and slice into small cubes to serve as croutons alongside the soup.
