Step-by-Step Instructions for Grilled Cheese Tomato Soup
Step 1: Sauté the Aromatics
In a large soup pot, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add 1 diced white onion and sauté for about 5-7 minutes until it becomes tender and slightly browned. The comforting aroma will fill your kitchen, creating the perfect base for your Grilled Cheese Tomato Soup.
Step 2: Season and Add Garlic
Stir in 1 teaspoon of Italian seasoning, ½ teaspoon of black pepper, ¼ teaspoon red pepper flakes, and 1 teaspoon of salt. Then, add 6 pressed cloves of garlic and sauté for an additional 1-2 minutes until fragrant, being careful not to brown the garlic. This step will amplify the flavors in your soup as they meld together beautifully.
Step 3: Incorporate Tomato Paste and Tomatoes
Next, mix in 2 tablespoons of tomato paste, allowing it to cook for about 2 minutes to enhance its richness. Then, pour in a can of 28 oz San Marzano tomatoes, breaking them up with your spoon. Add a handful of fresh basil and parsley, along with 1 teaspoon of sugar if desired. Stir well to combine all the ingredients.
Step 4: Add Stock and Simmer
Pour in 4 cups of chicken stock (or vegetable stock for a vegetarian option) and bring the mixture to a gentle simmer. Partially cover the pot, allowing the soup to cook for 20 minutes to meld all the flavors together. This simmering process is vital for achieving that comforting depth in your Grilled Cheese Tomato Soup.
Step 5: Blend the Soup
After the simmering time, carefully remove the pot from heat. Use an immersion blender to puree the soup until smooth, or transfer it in batches to a regular blender. Once blended, taste and adjust the seasoning as necessary to ensure the flavors are just right for your palate.
Step 6: Prepare the Garlic Toasts
While the soup cools slightly, preheat your oven to broil. Slice a French baguette into 1-inch thick pieces, then drizzle each slice with olive oil. Place them on a baking sheet and broil for about 2-3 minutes on each side until golden brown. Don’t forget to rub each slice with the reserved garlic for a burst of flavor!
Step 7: Assemble and Broil
In oven-safe bowls, ladle the hot soup and top it with the garlic toasts. Sprinkle with shredded Italian cheese blend or mozzarella on top. Carefully place the bowls under the broiler for 2-4 minutes, just until the cheese is melted and bubbly. This is the final touch that makes your Grilled Cheese Tomato Soup absolutely irresistible!
Step 8: Garnish and Serve
Remove the bowls from the oven and let them cool slightly. Garnish with chopped parsley for a fresh touch. Now, serve your delicious, creamy Grilled Cheese Tomato Soup with the cheesy toasts alongside for dipping. Feel free to enjoy every spoonful of this cozy dish!
