What Ingredients You Will Need for Creamy Tomato Basil Soup with Crispy Grilled Cheese Croutons
This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most ingredients are pantry staples, with fresh basil adding that bright, garden-fresh note.
- For the Soup:
- 2 tablespoons olive oil (extra virgin for best flavor)
- 1 medium onion, finely chopped
- 3 cloves garlic, minced (adds aromatic depth)
- 2 (28-ounce) cans whole peeled tomatoes (I prefer San Marzano for their sweetness)
- 2 cups vegetable or chicken broth (low sodium if possible)
- 1/2 cup heavy cream or full-fat coconut milk (for creaminess)
- 1 cup fresh basil leaves, roughly chopped
- 1 teaspoon sugar (balances acidity)
- Salt and freshly ground black pepper, to taste
- For the Crispy Grilled Cheese Croutons:
- 4 slices of sturdy bread (sourdough or country white works great)
- 4 slices sharp cheddar cheese (or your favorite melting cheese)
- 2 tablespoons unsalted butter, softened
Feel free to swap the heavy cream with a non-dairy option like coconut milk for a dairy-free twist. For a gluten-free option, use gluten-free bread for the croutons. When basil is out of season, dried basil works in a pinch, but fresh really makes a difference in flavor. For seasoning, I like to use a pinch more pepper than usual — it brings out the tomato’s natural sweetness beautifully.
Equipment Needed
- Large heavy-bottomed pot or Dutch oven (for even cooking and simmering)
- Immersion blender or regular blender (to achieve that silky smooth texture)
- Sharp chef’s knife (for chopping onions, garlic, and basil)
- Cutting board
- Non-stick skillet or grill pan (for making grilled cheese croutons)
- Wooden spoon or heatproof spatula (for stirring)
- Measuring cups and spoons
If you don’t have an immersion blender, a regular blender works just fine — just be careful with the hot soup and blend in batches. I’ve also used a food processor with good results. For the grilled cheese croutons, a cast-iron skillet gives the best crust, but a non-stick pan is easier to clean and works perfectly well. Butter knives for spreading and tongs for flipping will make your life easier too!
Preparation Method
- Sauté the Aromatics (10 minutes): Heat the olive oil in your pot over medium heat. Add the chopped onions and sauté until soft and translucent, about 5–7 minutes. Toss in the minced garlic and cook for another minute, until fragrant. Be careful not to let the garlic burn — that’s the kind of bitter flavor you don’t want sneaking in.
- Add Tomatoes & Broth (5 minutes): Pour in the canned tomatoes with their juices. Use a wooden spoon to break up the tomatoes a bit. Add the broth, sugar, salt, and pepper. Bring the mixture to a gentle boil, then reduce to a simmer. Let it cook uncovered for about 20 minutes, stirring occasionally. The tomatoes will break down and the flavors start to meld.
- Blend the Soup (5 minutes): Remove the pot from heat. Use an immersion blender to puree the soup until silky smooth (or carefully transfer to a blender in batches). If you want a chunkier texture, blend only half or pulse a few times. Return the soup to the pot.
- Add Cream & Basil (3 minutes): Stir in the heavy cream (or coconut milk) and fresh basil leaves. Heat gently over low heat until warmed through. Taste and adjust seasoning with salt and pepper. The basil should add a fresh, peppery note that brightens the rich tomato flavor.
- Prepare Grilled Cheese Croutons (10 minutes): Butter one side of each slice of bread. Place two slices, butter side down, in your skillet over medium heat. Add cheese slices on top, then cover with the other bread slices, butter side up. Cook until golden and crispy on one side, then flip carefully. Once both sides are golden and the cheese is melted, remove from heat. Let cool slightly, then cut into bite-sized cubes.
- Serve: Ladle the creamy tomato basil soup into bowls and float a handful of crispy grilled cheese croutons on top. They soak up the soup’s flavor but keep their crunch — it’s the best of both worlds.
If you find the soup too thick, stir in a bit more broth or cream. If it’s too thin, simmer a few extra minutes to concentrate the flavors. The grilled cheese croutons can be made ahead and crisped up again in a hot oven for a few minutes if needed.
Cooking Tips & Techniques
When making creamy tomato basil soup, patience really pays off. Taking the time to gently sauté onions and garlic brings out the base flavor that makes the soup sing. Don’t rush the simmering stage — it helps mellow the acidity of the tomatoes and deepen the flavor.
One mistake I’ve made (and learned from) is blending hot soup too rapidly in a countertop blender, which sometimes causes splatters or burns. Using an immersion blender right in the pot minimizes mess and keeps you safe.
When it comes to grilled cheese croutons, butter quality matters. Softened, unsalted butter spreads evenly and browns beautifully without smoking. Also, keep the heat moderate — high heat can burn the bread before the cheese melts inside.
For multitasking, start your soup first, and while it simmers, prep and cook your grilled cheese croutons. This way, everything’s ready to serve warm at the same time. If you want extra flavor, sprinkle a little smoked paprika or chili flakes into the soup during simmering for a mild kick.
Consistency is key: if your soup ends up too watery, blending in a handful of cooked rice or potato can thicken it naturally without changing the flavor.
Variations & Adaptations
- Dairy-Free Version: Swap heavy cream for coconut milk or cashew cream, and use dairy-free cheese slices for the croutons.
- Spicy Twist: Add a pinch of red pepper flakes or a splash of hot sauce to the soup for some heat.
- Roasted Tomato Basil Soup: Roast fresh tomatoes, onion, and garlic before blending to deepen the soup’s flavor.
- Low-Carb Option: Use almond flour bread or make cheesy crisps in the oven instead of grilled cheese croutons.
- Personal Favorite: I sometimes add a handful of fresh baby spinach or kale at the end for a subtle green boost and extra nutrients.
Adjust cooking times slightly if roasting or adding greens. This recipe is forgiving, so feel free to mix and match to suit your taste buds.
Serving & Storage Suggestions
Serve this creamy tomato basil soup hot with the crispy grilled cheese croutons freshly added on top. It pairs wonderfully with a light green salad or a glass of chilled white wine for a simple yet satisfying meal.
Store leftover soup in an airtight container in the refrigerator for up to 4 days. Keep grilled cheese croutons separate in a sealed bag or container to preserve their crunch. When reheating soup, warm gently on the stove and add a splash of broth or cream if needed.
To refresh croutons, pop them in a 350°F (175°C) oven for 5–7 minutes. Avoid microwaving them, as that tends to soften the crunch.
Flavors develop beautifully over time — the basil infuses deeper into the soup, and the sweetness of the tomatoes shines through even more. This makes it a great make-ahead meal for busy days.
