Let me tell you, the aroma of ripe tomatoes mingling with fresh basil and a hint of garlic simmering away on my stovetop is downright magical.

Years ago, when I was knee-high to a grasshopper, my grandma would make a big pot of tomato soup for chilly days.

Honestly, I wish I’d known this simple technique ages ago—it’s dangerously easy and delivers pure, nostalgic comfort every single time.

What Ingredients You Will Need

This cozy creamy tomato basil soup with grilled cheese croutons uses simple, wholesome ingredients to deliver bold flavor and satisfying texture—no complicated shopping required. Most are pantry staples or easy to swap for what you have on hand.

• For the Soup:
  • 2 pounds (900g) ripe tomatoes, quartered (Roma or plum work best for richer flavor)
  • 1 medium yellow onion, chopped
  • 4 garlic cloves, peeled
  • 2 tablespoons olive oil (extra virgin for best taste)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly cracked black pepper
  • 1 teaspoon sugar (balances the acidity)
  • 1 (28-ounce/800g) can crushed tomatoes (I like Muir Glen for their depth)
  • 2 cups (480ml) vegetable broth (low sodium recommended)
  • 1/2 cup (120ml) heavy cream (substitute half-and-half or coconut cream for dairy-free)
  • 1/4 cup (10g) fresh basil leaves, chopped (plus more for garnish)
  • Optional: pinch of red pepper flakes (for a little kick)
• For the Grilled Cheese Croutons:
  • 4 slices sourdough or hearty white bread (gluten-free bread works, too)
  • 4 ounces (115g) sharp cheddar cheese, sliced or grated (Swiss or Gouda are tasty swaps)
  • 2 tablespoons unsalted butter, softened

Ingredient Notes: If tomatoes aren’t at their peak, use canned fire-roasted tomatoes for extra flavor. For a vegan version, swap cream for coconut milk and cheese for plant-based slices (I actually tried Violife—pretty good!). In summer, toss in cherry tomatoes for sweetness. You can use dried basil in a pinch, but fresh makes all the difference.

Substitution Tips: Don’t have sourdough? Use any sturdy bread. Want it gluten-free? Swap in your favorite GF loaf. For a lighter soup, use milk instead of cream. If you like your soup spicy, up the red pepper flakes. I always say, make it your own!

Equipment Needed

• Large rimmed baking sheet (for roasting tomatoes)
• Chef’s knife and cutting board (for prepping veggies and bread)
• Large soup pot or Dutch oven
• Blender or immersion blender (a stick blender is my go-to for easy cleanup)
• Nonstick skillet or griddle (for the grilled cheese sandwiches)
• Spatula (for flipping grilled cheese)
• Measuring cups and spoons
• Ladle (for serving)
• Bowl for assembling croutons

If you don’t have a Dutch oven, a heavy-bottomed stockpot works just fine (I’ve used my old stainless pot many times—no complaints!). For the croutons, a panini press gives extra crunch, but a regular skillet does the job. Keep your blender blades sharp—dull ones make the soup less creamy. Store your tools dry and clean, especially the immersion blender (it’s a lifesaver for soups!). You don’t need fancy gadgets—a simple setup is perfect.

Preparation Method

1. Roast the Tomatoes: Preheat your oven to 400°F (200°C). Arrange quartered tomatoes, onions, and garlic cloves on a baking sheet. Drizzle with olive oil, sprinkle with salt, pepper, and sugar. Roast for 25-30 minutes until tomatoes are soft and caramelized on the edges. (Tip: Don’t rush this—roasting adds depth. Your kitchen will smell incredible!)
2. Prepare the Soup Base: Transfer roasted veggies to your soup pot. Add canned crushed tomatoes and vegetable broth. Bring to a boil over medium-high heat, then reduce to a simmer for 10 minutes. (Troubleshooting: If your tomatoes look dry, add a splash more broth.)
3. Blend Until Smooth: Remove from heat. Use an immersion blender to puree the soup until velvety smooth. Or, work in batches with a countertop blender—just be careful, hot liquids can splatter! (Note: If you like it chunky, blend less; for ultra-smooth, blend longer.)
4. Add Cream and Basil: Stir in heavy cream and chopped basil. Simmer for another 5 minutes. Taste and adjust seasoning—add more salt, pepper, or a pinch of red pepper flakes if you want a little heat. (Sensory cue: The soup should be creamy with flecks of green and a rich tomato aroma.)
5. Make Grilled Cheese Sandwiches: Butter one side of each bread slice. Place half the cheese on two slices, top with the other bread, buttered side out. In a skillet over medium heat, cook sandwiches 2-3 minutes per side until golden and cheese is melted. (Efficiency tip: While soup simmers, make the sandwiches!)
6. Make Croutons: Let grilled cheese sandwiches cool slightly, then cut into 1-inch (2.5cm) cubes. (Warning: Too hot and the cheese will ooze everywhere—wait five minutes.)
7. Serve: Ladle soup into bowls, top generously with grilled cheese croutons, and a sprinkle of fresh basil. (Personal tip: Add a drizzle of olive oil for restaurant vibes.)

Time Estimates: Roasting – 30 minutes; Soup simmering – 15 minutes; Sandwiches – 10 minutes; Assembly – 5 minutes. Total: About 40 minutes start to finish.

If your soup turns out too thick, just stir in a splash of broth. If too thin, simmer uncovered for a few minutes. Trust your senses—if it smells “just right” and looks creamy, you’re good!

Cooking Tips & Techniques

Here’s what I’ve learned after making creamy tomato basil soup with grilled cheese croutons more times than I can count (and a few fails, too):

• Roasting is Key: Always roast those tomatoes—raw ones just don’t pack the same punch. Let them get some color for flavor depth.
• Blend Carefully: Hot soup can splatter. If using a blender, vent the lid and cover with a towel. I learned the hard way—once had tomato soup on the ceiling!
• Seasoning Matters: Taste as you go. Tomatoes vary in sweetness, so that pinch of sugar helps balance acidity. Don’t be afraid to add more salt if it tastes flat.
• Grilled Cheese Crunch: Let the sandwiches cool before cubing. If you rush, the cheese slides out. For extra crunch, toast the cubes briefly in a dry skillet.
• Multitask: Make sandwiches while the soup simmers. Keeps things efficient and dinner hits the table faster.
• Consistency: Want thinner soup? Add broth. Thicker? Simmer longer. I like mine somewhere in the middle—creamy but not gloopy.
• Fresh Basil: Stir in basil right at the end. Cooking it too long dulls the flavor.

Biggest mistake? Over-blending with too much cream. It can water down the tomato flavor. Start with less, then add more to taste. And don’t forget those grilled cheese croutons—they make all the difference!

Variations & Adaptations

This creamy tomato basil soup recipe is endlessly customizable. Here are some of my favorite tweaks (tried and true, you know):

• Vegan Version: Swap heavy cream for full-fat coconut milk and use dairy-free cheese and bread for the croutons. Still super creamy!
• Low-Carb/Gluten-Free: Use gluten-free bread for the croutons or skip them and serve with roasted chickpeas for crunch.
• Spicy Kick: Add a chopped jalapeño or a dash of hot sauce to the soup base for a fiery twist.
• Seasonal Add-Ins: In summer, toss in fresh corn kernels or zucchini. In winter, add roasted red peppers for deeper flavor.
• Different Cheese: Try Gruyère, fontina, or even blue cheese for the croutons. My personal favorite is sharp cheddar and Swiss combo—melts like a dream.
• Cooking Methods: Make the soup in a slow cooker for extra convenience (just dump everything in and blend before serving).
• Allergen Substitutes: For nut allergies, choose seed-based breads and cheese alternatives. For lactose intolerance, coconut cream and vegan cheese do the trick.

I once tossed in a handful of spinach for extra greens—no one noticed, but I felt a little more virtuous! Don’t be afraid to get creative. Your kitchen, your rules.

Serving & Storage Suggestions

Serving: This creamy tomato basil soup is best served piping hot, in deep bowls topped with a generous handful of grilled cheese croutons and a sprinkle of fresh basil. Honestly, it looks gorgeous in rustic pottery or even simple mugs (perfect for cozy nights on the couch).

If you’re feeling fancy, drizzle with a touch of olive oil or a swirl of cream. Pair with a crisp green salad, roasted veggies, or even a glass of light red wine—Syrah and Pinot Noir work well. For the younger crowd, serve with apple slices or carrot sticks.

Storage: Store leftover soup in an airtight container in the refrigerator for up to 4 days. The flavors deepen overnight (even better the next day!). The croutons should be kept separate in a sealed container at room temperature for up to 2 days, or refrigerated if you used dairy-free cheese.

Reheating: Warm soup gently on the stovetop over medium heat, stirring occasionally. If it thickens too much, add a splash of broth. Reheat croutons in a dry skillet or toaster oven to restore crunch. Avoid microwaving the croutons—they get soggy.

Pro tip: Freeze soup (without croutons) for up to 2 months. Thaw in the fridge overnight, then reheat and top with fresh croutons.
