What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or easy to find at your local store, and substitutions are straightforward.

• For the Soup:
• 2 tablespoons olive oil (for sautéing)
• 1 medium yellow onion, finely chopped (adds sweetness and depth)
• 3 cloves garlic, minced (fresh is best for vibrant flavor)
• 2 (28-ounce) cans crushed tomatoes (I swear by San Marzano brand for authentic taste)
• 2 cups low-sodium vegetable broth (or chicken broth for richer flavor)
• 1 cup heavy cream or half-and-half (for that creamy texture)
• 1/2 cup fresh basil leaves, chopped (can’t skip this—fresh basil is key)
• 1 teaspoon sugar (balances acidity from tomatoes)
• Salt and freshly ground black pepper, to taste
• For the Crispy Grilled Cheese Croutons:
• 4 slices sourdough or country white bread (day-old bread works great)
• 4 slices sharp cheddar cheese (or a blend with mozzarella for extra gooeyness)
• 2 tablespoons unsalted butter, softened (I like Kerrygold for richness)

Ingredient Tips: If you want a dairy-free version, swap the cream for coconut milk and use vegan cheese slices. For a gluten-free alternative, gluten-free bread works well for the croutons. And if fresh basil is out of season, frozen basil can be a decent fallback, though it won’t be quite as vibrant.

Equipment Needed

• Large heavy-bottomed pot or Dutch oven (for sautéing and simmering the soup)
• Immersion blender or countertop blender (to puree the soup to creamy perfection)
• Large skillet or griddle (for making grilled cheese croutons crisp and golden)
• Wooden spoon or silicone spatula (to stir the soup gently)
• Sharp knife and cutting board (for chopping onion, garlic, and basil)
• Measuring cups and spoons (for accurate ingredient amounts)

If you don’t have an immersion blender, a regular blender works well—just be careful blending hot liquids and do it in batches. For those on a budget, a nonstick skillet for grilled cheese is often easier to clean and still gives great results. Keeping your butter softened at room temperature makes spreading it on the bread easier, so plan ahead a bit!

Preparation Method

1. Prepare the base: Heat 2 tablespoons olive oil in your large pot over medium heat. Add the chopped onion and sauté for about 5-7 minutes until it’s soft and translucent—this sweetens the soup naturally. Toss in the minced garlic and cook for another 1-2 minutes until fragrant. Don’t let the garlic brown, or it’ll get bitter.
2. Add the tomatoes and broth: Pour in the crushed tomatoes along with their juices and the vegetable broth. Stir in the teaspoon of sugar to mellow the acidity. Bring everything to a gentle boil, then reduce the heat and simmer uncovered for 20 minutes. This helps deepen the flavors and thicken the soup slightly.
3. Blend the soup: Remove the pot from heat, and using an immersion blender, puree the soup until smooth but leave a bit of texture if you like (I do). If you’re using a regular blender, carefully ladle the soup in batches and blend until creamy.
4. Add cream and basil: Return the soup to low heat and stir in the heavy cream and chopped fresh basil. Let it warm through for about 5 minutes. Taste and season with salt and pepper as needed. You want it bright but balanced.
5. Make the grilled cheese croutons: While the soup simmers, butter one side of each bread slice. Place two slices butter-side down on your skillet over medium heat, top each with a slice of cheddar, then the other bread slice butter-side up. Grill until golden brown and cheese is melted, about 3-4 minutes per side. Once done, let cool slightly, then cut into bite-sized cubes.
6. Serve: Ladle the creamy tomato basil soup into bowls and scatter the crispy grilled cheese croutons on top. They soak up the soup’s flavor but stay satisfyingly crunchy. Garnish with a few extra basil leaves if you’re feeling fancy.

Pro tip: Keep the heat moderate when grilling the cheese; too hot and the bread burns before the cheese melts. Patience pays off here!

Cooking Tips & Techniques for the Best Tomato Basil Soup

Let me share some practical tips to get your creamy tomato basil soup just right. First, never rush the onion sauté. Those sweet, soft onions form the flavor backbone, so give them the time to develop their character. Also, fresh garlic adds a punch, but burnt garlic can ruin the whole batch—watch it closely.

When pureeing, I prefer an immersion blender because it’s less messy and you can control the texture better. But if you only have a regular blender, blend in small batches and leave the vent slightly open to prevent steam buildup. Always cool the soup slightly before blending to avoid splatters.

About the basil—add it towards the end so it keeps its fresh, bright flavor. Cooking it too long dulls that signature aroma. And don’t skip the grilled cheese croutons! Buttering the bread generously ensures crispy, golden edges, while good-quality sharp cheddar gives that perfect melty, tangy bite.

Common mistake? Making the soup too thin. If that happens, just simmer a bit longer uncovered to reduce. Also, don’t over-season at the start; it’s easier to add salt later than fix an overly salty pot. Timing-wise, make the soup first, then grill the cheese croutons while it simmers—keeps everything hot and fresh.

Variations & Adaptations

This creamy tomato basil soup with crispy grilled cheese croutons is versatile—here are a few ways to make it your own:

• Dairy-Free Version: Swap the heavy cream for full-fat coconut milk and use vegan cheese slices for the croutons. It’s still creamy and indulgent without dairy.
• Spicy Twist: Add a pinch of red pepper flakes when sautéing the onions or swirl in some chipotle hot sauce for a smoky kick.
• Roasted Tomato Basil: Roast fresh tomatoes and garlic beforehand for a deeper, slightly caramelized flavor. Then proceed with the recipe as usual.
• Different Cheeses: Try gruyere or fontina for the grilled cheese croutons for a nuttier, richer flavor profile.
• Low-Carb Option: Use keto-friendly bread or crisp, baked cheese crisps instead of bread croutons for a grain-free crunch.

I personally tried adding a swirl of pesto on top once, and it added a lovely herby brightness that paired beautifully with the creamy soup base. Feel free to experiment with whatever herbs or cheeses you love!

Serving & Storage Suggestions

This soup is best served hot—right out of the pot—so those grilled cheese croutons stay delightfully crispy. Serve it in rustic bowls garnished with extra fresh basil leaves or a drizzle of cream for a pretty touch. It pairs wonderfully with a crisp green salad or a simple glass of chilled white wine.

Leftovers? No worries. The soup keeps well in the refrigerator for up to 4 days in an airtight container. Reheat gently on the stovetop over low heat, stirring frequently to prevent scorching. If the soup thickens too much after refrigeration, add a splash of broth or water to loosen it up.

The grilled cheese croutons, however, are best eaten fresh. They can be stored separately in an airtight container at room temperature for a day or two but lose their crunch over time. If you want to prep ahead, keep the croutons separate and add them just before serving.

Flavors tend to deepen overnight, so leftovers often taste even better the next day—if you can resist eating it all the first time around!

Nutritional Information & Benefits
