For the Soup
- 1 head of garlic
- 3 red bell peppers, halved and deseeded
- 10 oz carrots, cut into 1-inch pieces (~5 large carrots)
- 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)
For Grilled Cheese Croutons
- 2 slices of bread (we used sourdough)
- 2-3 slices cheddar or American cheese
- 1-2 tablespoons butter
How to Make Sheet Pan Soup
Step 1: Preheat the Oven
Preheat your oven to 400˚F. This temperature will help roast the vegetables to perfection.
Step 2: Prepare the Garlic
Slice off the top of the head of garlic to expose the cloves. You’ll only use half in this recipe but roast the entire head so you can save extra cloves for another dish.
Step 3: Arrange Your Vegetables
Place the bell peppers (skin side up), carrots, cauliflower, tomatoes, garlic, and onion on a large baking sheet. Drizzle them with olive oil and sprinkle with salt, smoked paprika, cayenne pepper, and cumin.
Step 4: Roast Until Tender
Roast in your preheated oven for about 40-45 minutes until all vegetables are fork-tender.
Step 5: Heat Your Broth
About 10 minutes before your vegetables finish roasting, add your chicken or vegetable broth to a small pan over medium heat or microwave until hot.
Step 6: Blend It All Together
Once your veggies are done roasting, combine them in a blender with half of the roasted garlic cloves (save the other half). Add in the hot broth and lemon juice. Blend until you reach a smooth consistency. Taste and adjust seasoning with remaining salt if needed.
Step 7: Serve Hot
Enjoy your soup hot! Pair it with grilled cheese or turn it into croutons by following these steps.
Step 8: Make Grilled Cheese Croutons
To prepare grilled cheese croutons:
1. Heat butter in a pan over medium-low heat.
2. Toast bread until golden brown on one side.
3. Flip one slice over; add cheese slices on top.
4. Place the other slice on top (cooked side down), cover with a lid.
5. Cook until both sides are crispy and cheese melts completely.
6. Remove from heat and cut into small cubes for topping your soup!

Common Mistakes to Avoid
Making Sheet Pan Soup is fun and easy, but some common mistakes can hinder your results. Here are a few pitfalls to avoid:
- Skipping the Preheating: Not preheating your oven can lead to uneven cooking. Always preheat before roasting your vegetables for the best texture.
- Overcrowding the Pan: If you pile too many veggies on the sheet pan, they will steam instead of roast. Give each ingredient enough space to caramelize properly.
- Not Seasoning Properly: Failing to season adequately can result in bland soup. Use the recommended spices and taste before serving to adjust seasoning as needed.
- Ignoring the Blending Step: Skipping blending will leave your soup chunky instead of smooth. Blend thoroughly for a creamy texture that enhances flavor.
- Using Cold Broth: Adding cold broth to hot vegetables can cool down the mixture. Heat your broth first to maintain the desired temperature of the soup.
- Forgetting About Leftovers: Leaving soup out at room temperature too long can lead to spoilage. Store leftover soup promptly for future meals.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 3-4 days.

- Freeze in freezer-safe containers or heavy-duty freezer bags for up to 3 months.
