What Ingredients You Will Need

This creamy tomato basil soup with crispy grilled cheese croutons uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are easy to find and pantry staples, making this recipe accessible anytime you want that cozy feel.

  • For the Soup:
    • 2 tablespoons extra-virgin olive oil (adds richness and depth)
    • 1 medium yellow onion, finely chopped
    • 3 cloves garlic, minced
    • 2 (28-ounce) cans of whole peeled tomatoes (San Marzano if possible for best flavor)
    • 1 cup vegetable or chicken broth (low sodium preferred)
    • 1 cup heavy cream or half-and-half (for that velvety smoothness)
    • 1/2 cup fresh basil leaves, roughly chopped
    • 1 teaspoon granulated sugar (balances acidity)
    • Salt and freshly ground black pepper, to taste
  • For the Crispy Grilled Cheese Croutons:
    • 4 slices white or sourdough bread (day-old bread works great)
    • 4 slices sharp cheddar cheese (I prefer Cabot for meltiness and flavor)
    • 2 tablespoons unsalted butter, softened

Pro Tip: You can swap heavy cream for coconut cream if you want a dairy-free option, and use gluten-free bread to keep it allergy-friendly. In summer, fresh vine-ripened tomatoes can replace canned for a bright, garden-fresh twist.

Equipment Needed

  • Large heavy-bottomed pot or Dutch oven: For simmering the soup evenly without burning.
  • Immersion blender: Makes pureeing the soup right in the pot a breeze—no hot transfers! Alternatively, a regular blender works but be careful with hot liquids.
  • Non-stick skillet or griddle pan: To cook the grilled cheese sandwiches evenly and get that perfect golden crust.
  • Sharp chef’s knife: For chopping onions, garlic, and basil.
  • Cutting board and ladle: Basic but essential.

If you don’t have an immersion blender, no worries—a regular blender or food processor will do, but just blend in batches and hold down the lid tightly. For budget-friendly options, a sturdy saucepan and a cast-iron skillet work beautifully too. Maintaining your skillet with a light seasoning keeps it non-stick and ready for crispy grilled cheese every time.

Preparation Method

creamy tomato basil soup preparation steps

  1. Sauté the aromatics: Heat 2 tablespoons olive oil in your large pot over medium heat. Add the chopped onion and cook for about 5 minutes until translucent and soft. Toss in the minced garlic and cook for another 1-2 minutes, just until fragrant—don’t let it brown or it’ll taste bitter.
  2. Add the tomatoes and broth: Pour in the canned tomatoes with their juice, breaking them up with your spoon. Add the broth and stir to combine. Bring the mixture to a gentle simmer, then reduce heat to low and cook uncovered for 25 minutes. This helps meld flavors and thickens the soup slightly.
  3. Blend the soup: Remove the pot from heat. Using your immersion blender, puree the soup until smooth and creamy. If using a regular blender, blend in batches, filling only halfway and venting the lid.
  4. Finish with cream and basil: Return the soup to low heat. Stir in the heavy cream, chopped fresh basil, and sugar. Season with salt and pepper to taste. Warm through for 5 minutes but avoid boiling once cream is added to prevent curdling.
  5. Prepare the grilled cheese croutons: Butter one side of each bread slice. Place two slices, butter side down, on a heated non-stick skillet over medium heat. Add a slice of cheddar cheese on each, then top with the remaining bread slices, butter side up. Cook for 3-4 minutes per side until golden brown and cheese is melted.
  6. Cut into croutons: Let the grilled cheese sandwiches cool slightly, then cut into bite-sized cubes. These will add that irresistible crunch and melty cheese burst on top of your soup.
  7. Serve: Ladle the creamy tomato basil soup into bowls and sprinkle generously with crispy grilled cheese croutons. Garnish with extra basil leaves if you like, and enjoy immediately.

Pro Tip: If your soup feels too thick, add a splash more broth or cream. If too thin, simmer a little longer uncovered. The grilled cheese croutons can also be made ahead and reheated in the oven to regain crispness.

Cooking Tips & Techniques for the Perfect Creamy Tomato Basil Soup

Getting the perfect creamy tomato basil soup with crispy grilled cheese croutons is all about balance and timing. Here’s what I’ve learned from plenty of trial and error:

  • Use quality canned tomatoes: San Marzano tomatoes bring natural sweetness and depth. Avoid plain diced tomatoes—they can be too watery.
  • Don’t rush the simmer: Letting the soup cook uncovered for at least 25 minutes concentrates flavors and reduces excess liquid.
  • Blend carefully: Hot soups can splatter during blending—immerse your blender fully or use a towel to cover the blender lid for safety.
  • Add cream last: Adding dairy too early can cause curdling. Stir it in once the soup is off the highest heat and warm gently.
  • Butter the bread generously: This ensures the grilled cheese croutons crisp up beautifully without sticking or burning.
  • Cook grilled cheese slowly: Medium heat is your friend here. Too hot and you get burnt crust with unmelted cheese inside.

One thing I learned the hard way? Overloading the soup with basil can turn it bitter. Keep it fresh and bright, but not overpowering. Also, cut your grilled cheese croutons just before serving to keep them crispy and melty—once soggy, there’s no going back!

Variations & Adaptations

This creamy tomato basil soup with crispy grilled cheese croutons is wonderfully versatile. Here are some tasty ways to switch things up:

  • Dairy-Free Version: Swap heavy cream for coconut milk or cashew cream. Use vegan butter and dairy-free cheese slices for the grilled cheese croutons.
  • Spicy Kick: Add a pinch of red pepper flakes or a dash of smoked paprika to the soup for a subtle heat.
  • Seasonal Twist: In summer, use fresh, ripe tomatoes and add a handful of fresh spinach or kale for extra greens.
  • Different Cheeses: Try gruyère or mozzarella in your grilled cheese for a different melty flavor profile.
  • Low-Carb Option: Use almond flour bread or make grilled cheese croutons with thinly sliced zucchini grilled with cheese melted on top.

Personally, I once made this soup with a swirl of pesto instead of fresh basil—it was a vibrant flavor hit, though the classic basil version remains my go-to comfort meal. Don’t be shy about tweaking to your liking!

Serving & Storage Suggestions

This creamy tomato basil soup is best served hot and fresh, straight from the pot with those crispy grilled cheese croutons piled generously on top. A sprinkle of extra fresh basil or a drizzle of good olive oil adds a nice touch. Pair it with a crisp green salad or roasted veggies for a full meal, and a chilled glass of white wine or a warm cup of herbal tea complements the cozy vibe perfectly.

To store, keep the soup in an airtight container in the refrigerator for up to 4 days. The grilled cheese croutons are best stored separately to avoid sogginess and can be reheated in a toaster oven or skillet to crisp back up. For longer storage, freeze the soup (without croutons) for up to 3 months—thaw overnight in the fridge before reheating gently on the stove.

Reheating the soup slowly on the stove helps the flavors develop even more, and you might find the basil aroma intensifies beautifully after a day or two. Just add the grilled cheese croutons right before serving to keep that satisfying crunch intact.

Nutritional Information & Benefits

This creamy tomato basil soup is packed with nutrients from fresh tomatoes and basil, both rich in antioxidants like lycopene and vitamin C. The inclusion of cream adds calories and fat for richness, but you can adjust that by using half-and-half or plant-based alternatives. Tomatoes support heart health and have anti-inflammatory properties, while basil contributes antibacterial benefits and a fresh herbal punch.

Each serving (about 1.5 cups soup + grilled cheese croutons) provides roughly 300–400 calories, depending on cream and bread choices. It’s gluten-friendly if you swap bread for gluten-free options, and can easily be dairy-free with simple substitutions. This recipe strikes a good balance between indulgence and nourishment, making it a satisfying meal that feels like a treat without guilt.

If you’re looking for a creamy tomato basil soup with crispy grilled cheese croutons that’s both comforting and impressively easy, you’re in the right place. This recipe brings together simple ingredients in a way that feels special without fuss. I love how the soup’s velvety texture pairs with those crunchy, cheesy croutons—honestly, it’s like a warm hug on a plate.
