Roasted Tomato & Garlic Soup with Crispy Grilled Cheese
This cozy roasted tomato and garlic soup is made by roasting ripe tomatoes, red onion, and whole garlic cloves until deeply caramelized, then blending everything into a smooth, rich tomato soup. A swirl of cream or Greek yogurt adds a velvety finish, while a golden grilled-cheese sandwich makes it a wonderfully comforting meal.

Ingredients
For the Roasted Tomato Soup
- 2 lb (900 g) ripe tomatoes, halved
- 1 large red onion, cut into wedges
- 1 whole garlic bulb, cloves separated and peeled
- 2 tbsp olive oil
- 1 tsp dried Italian seasoning
- ½ tsp dried oregano
- ½ tsp smoked paprika
- ½ tsp freshly ground black pepper
- ½ tsp salt, or to taste
- 3 cups (720 ml) vegetable or chicken broth
- 1 tbsp tomato paste
- 1 tsp sugar or honey, optional, if the tomatoes are very acidic
- ½ cup (120 ml) heavy cream, half-and-half, or plain Greek yogurt
- 1 tbsp fresh basil or parsley, chopped
- 1–2 tsp lemon juice, optional
For the Grilled Cheese
- 8 slices bread
- 4–6 slices cheddar, mozzarella, or your preferred melting cheese
- 2 tbsp softened butter
- Optional: ¼ tsp garlic powder
- Optional: ½ tsp dried Italian herbs
Instructions
1. Prepare the vegetables.
Preheat your oven to 425°F (220°C). Arrange the halved tomatoes and red onion wedges on a large baking sheet.
2. Add the garlic.
Scatter the peeled garlic cloves among the tomatoes and onions. Keeping the garlic pieces together with the vegetables allows them to roast and become soft and sweet.
3. Season everything.
Drizzle the vegetables with olive oil and sprinkle with Italian seasoning, oregano, smoked paprika, black pepper, and salt.
4. Roast until caramelized.
Roast for approximately 35–40 minutes, turning the tray once if needed. The tomatoes should become soft and slightly browned around the edges, while the onions and garlic should be tender.
5. Transfer to a blender.
Carefully transfer the roasted vegetables to a blender. Add about 1½ cups of the broth and blend until smooth.
6. Blend carefully.
Hot liquids can create pressure in a blender, so work carefully and follow your blender manufacturer’s instructions. Alternatively, use an immersion blender directly in the cooking pot.
7. Build the soup.
Pour the blended mixture into a large saucepan. Add the remaining broth and tomato paste.
8. Simmer.
Bring the soup to a gentle simmer over medium-low heat. Cook for about 8–10 minutes, stirring occasionally.
9. Adjust the flavor.
Taste the soup. If the tomatoes are particularly tart, a small amount of sugar or honey can balance the acidity. Add additional salt, pepper, or herbs as needed.
10. Make it creamy.
Reduce the heat to low and stir in the cream. If using Greek yogurt instead, temper it with a little warm soup first before stirring it into the pot to help prevent curdling.
11. Finish the soup.
Add fresh basil or parsley and a small squeeze of lemon juice if desired. The lemon brightens the roasted tomato flavor without making the soup taste lemony.
12. Prepare the sandwiches.
Spread softened butter over one side of each bread slice. For extra flavor, mix a little garlic powder or Italian seasoning into the butter.
13. Assemble.
Place cheese between two slices of bread, keeping the buttered sides facing outward.
14. Cook the grilled cheese.
Heat a skillet over medium-low heat. Place the sandwiches in the skillet and cook for about 3–4 minutes per side, until the bread is deeply golden and the cheese has melted.
15. Avoid excessive heat.
Medium-low heat is ideal because it gives the cheese time to melt before the bread becomes too dark.
16. Rest briefly.
Transfer the grilled cheese sandwiches to a cutting board and let them rest for 1–2 minutes before cutting.
17. Serve the soup.
Ladle the hot roasted tomato soup into bowls.
18. Add the finishing touch.
Top each bowl with a small swirl of cream or yogurt and a sprinkle of dried herbs or freshly chopped basil.
19. Add the sandwich.
Cut the grilled cheese diagonally and serve alongside the soup for dipping.
20. Enjoy immediately.
The contrast between the silky roasted tomato soup and crisp, cheesy grilled bread makes this an especially satisfying combination.
Why Roasting Makes This Soup Special
Roasting the tomatoes before blending them gives the soup a much deeper flavor than simply simmering raw tomatoes. The tomatoes lose some moisture while their natural sweetness becomes more concentrated. The red onion also becomes softer and sweeter, while roasted garlic develops a mellow flavor.
Easy Variations
Extra herby: Add fresh basil, thyme, or oregano after blending.
Spicy: Add a pinch of red-pepper flakes or a little chili powder before roasting.
Extra creamy: Increase the cream slightly or blend in a small amount of cream cheese.
Dairy-free: Use vegetable broth and an unsweetened plant-based cream alternative, and serve with dairy-free grilled cheese.
More texture: Reserve a few roasted tomato pieces and stir them into the finished soup instead of blending everything completely smooth.
Serving Suggestions
Serve this soup with grilled cheese, crusty bread, garlic toast, a simple green salad, or roasted vegetables. For a more substantial meal, you can add beans, shredded chicken, or another protein-rich side.
Storage
Allow leftover soup to cool promptly and transfer it to an airtight container. USDA guidance recommends using refrigerated leftovers within 3–4 days, while properly frozen leftovers can generally be kept for longer-term storage. (USDA Ask FSIS)
For the best texture, store the soup separately from grilled cheese. Reheat the soup gently on the stovetop or in the microwave, stirring between heating intervals.
