About this recipe

The ultimate comfort food duo — a rich, velvety tomato soup made from scratch with canned San Marzano tomatoes, a touch of cream, and fresh basil, paired with a perfectly golden, buttery grilled cheese sandwich with gooey melted cheddar and American cheese. Simple, reliable, and deeply satisfying every single time.

Instructions

1. 1

   In a large saucepan over ^[medium heat], melt the butter. Add the diced yellow onion and cook, stirring occasionally, until softened and translucent, about 6–8 minutes. Do not rush this step — properly softened onions build a sweet, savory base for the soup.

2. 2

   Add the minced garlic and tomato paste. Stir constantly and cook for 1–2 minutes until the garlic is fragrant and the tomato paste darkens slightly in color. This step deepens the tomato flavor.

3. 3

   Pour in the canned san marzano peeled tomatoes (with all their juices), chicken broth, sugar, dried oregano, and red pepper flakes if using. Use a wooden spoon to crush the whole tomatoes against the side of the pot. Stir to combine and bring to a boil.

4. 4

   Reduce heat to ^[low] and simmer uncovered for 20 minutes, stirring occasionally, until the soup has thickened slightly and the flavors have melded together.

5. 5

   Remove the pot from heat. Add the torn fresh basil leaves. Using an immersion blender, blend the soup directly in the pot until completely smooth and velvety. Alternatively, carefully transfer in batches to a blender.

6. 6

   Return the pot to ^[low heat]. Stir in the heavy cream and season with salt and black pepper to taste. Keep warm on the lowest heat setting while you make the grilled cheese sandwiches.

7. 7

   Lay out all 8 slices of sandwich bread. Spread a thin, even layer of softened butter on one side of each slice. For an extra golden, crispy crust, mix a small amount of mayonnaise into the butter before spreading — this is the secret to diner-style grilled cheese.

8. 8

   Flip 4 slices of sandwich bread butter-side down. Layer 2 slices of sharp cheddar cheese and 1 slice of American cheese on each. Top with the remaining sandwich bread slices, butter-side up.

9. 9

   Heat a large skillet over ^[medium-low heat]. Place 1–2 sandwiches in the skillet (do not crowd). Cook for 3–4 minutes until the bottom is deep golden brown and the cheese begins to melt.

10. 10

    Carefully flip each sandwich and press down gently with a spatula. Cook for another 3–4 minutes until the second side is evenly golden and the cheese is fully melted. Repeat with remaining sandwiches.

11. 11

    Transfer sandwiches to a cutting board and let rest for 1 minute before slicing diagonally. This prevents the cheese from sliding out immediately.

12. 12

    Ladle the hot tomato soup into bowls. Serve immediately alongside the grilled cheese sandwiches. Optionally garnish the soup with a drizzle of cream, a few fresh basil leaves, or a crack of black pepper.
