What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples or easy to swap based on what you have.

• For the Soup Base:
• 28 oz (800 g) canned whole peeled tomatoes (preferably San Marzano for rich flavor)
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced
• 2 cups (480 ml) vegetable or chicken broth (low sodium if possible)
• 1/2 cup (120 g) cottage cheese (look for small-curd varieties; adds creaminess without heaviness)
• 1/4 cup (60 ml) heavy cream or full-fat coconut milk (optional for extra richness)
• 1/4 cup (15 g) fresh basil leaves, roughly chopped
• 2 tbsp olive oil (use a fruity, extra virgin variety for best aroma)
• 1 tsp sugar (balances tomato acidity)
• Salt and freshly ground black pepper, to taste
• For the Crispy Grilled Cheese Croutons:
• 4 slices sturdy sandwich bread (like sourdough or country white, day-old works great)
• 4 oz (115 g) sharp cheddar cheese, sliced or shredded (I love Cabot for melt and flavor)
• 2 tbsp unsalted butter, softened
• 1 small garlic clove, minced (optional, for garlic butter flavor)

Ingredient notes: If you want a dairy-free version, swap cottage cheese with blended silken tofu and use coconut milk instead of cream. For gluten-free, use gluten-free bread and check broth labels. In summer, fresh ripe tomatoes can replace canned, just roast them first for that deep flavor.

Equipment Needed

• Large heavy-bottomed pot or Dutch oven – essential for even heat and preventing sticking
• Immersion blender or regular blender – to puree the soup smoothly
• Chef’s knife and cutting board – for chopping onions, garlic, and basil
• Nonstick skillet or cast iron pan – for making grilled cheese croutons with a nice golden crust
• Measuring cups and spoons – for precise seasoning and broth

If you don’t have an immersion blender, a regular blender works fine; just be sure to blend the soup in batches to avoid splattering. For the grilled cheese, a cast iron skillet gives a beautiful crust, but a well-seasoned nonstick pan works just as well—and cleanup is easier. I’ve used both, and honestly, the flavor difference is subtle but the cast iron gives that satisfying sear you notice (plus it holds heat nicely for multiple batches).

For budget-friendly cooks, a simple saucepan and a handheld blender will do just fine. Just keep an eye on the heat when toasting the croutons so they don’t burn.

Preparation Method

1. Sauté the aromatics: Heat 2 tablespoons olive oil in a large pot over medium heat. Add the chopped onion and a pinch of salt, cooking for about 5 minutes until soft and translucent. Toss in the minced garlic and cook for another minute until fragrant—don’t let it brown or it’ll turn bitter.
2. Add the tomatoes and broth: Pour in the canned whole peeled tomatoes with their juices. Use a wooden spoon to break them up a bit. Add the vegetable or chicken broth and stir in 1 teaspoon sugar. Bring to a gentle simmer and let cook for 15 minutes, uncovered. This allows flavors to meld and the soup to thicken slightly.
3. Blend for creaminess: Remove from heat and carefully puree the soup with an immersion blender until silky smooth. If using a regular blender, blend in small batches and return to the pot.
4. Add cottage cheese and basil: Stir in the cottage cheese and chopped fresh basil. If you want extra richness, add the heavy cream or coconut milk now. Return the pot to low heat and warm through for 5 minutes. Taste and adjust seasoning with salt and pepper.
5. Prepare grilled cheese croutons: While the soup simmers, mix softened butter with minced garlic. Spread the garlic butter evenly on one side of each bread slice. Place a generous layer of sharp cheddar cheese on the unbuttered side, then top with the buttered slice, butter side out.
6. Cook the sandwiches: Heat a skillet over medium heat. Grill the sandwiches for 3-4 minutes on each side, pressing lightly, until the bread is golden brown and cheese is melted. Remove and let cool slightly. Cut into bite-sized cubes.
7. Serve: Ladle the creamy tomato basil soup into bowls and top with a handful of crispy grilled cheese croutons. The contrast between warm, silky soup and crunchy, cheesy bites is delightful.

Pro tip: If the soup feels too thick after blending, just stir in a splash more broth or water to reach your preferred consistency. And don’t rush the grilling of the cheese—medium heat helps the cheese melt perfectly without burning the bread.

Cooking Tips & Techniques

Getting this soup just right is easier than it seems, but a few tricks from my kitchen experiments make a big difference:

• Don’t rush the tomato simmer: Letting the tomatoes gently cook with broth and onion develops a mellow flavor and reduces acidity. Skipping this step often leads to a sharper, less balanced soup.
• Blend carefully: Puree while the soup is warm, not boiling hot, to avoid splashing. An immersion blender is my favorite for quick cleanup, but a regular blender works too—just cool the soup slightly first.
• Choose the right bread for grilled cheese croutons: Day-old or slightly firm bread holds up better when cut into croutons and tossed on soup. Soft, fresh bread can get soggy too fast.
• Garlic butter makes all the difference: Mixing minced garlic into softened butter before grilling the sandwiches adds a subtle savory note that lingers with every bite.
• Don’t skip the cottage cheese: It’s a sneaky way to make the soup creamy and protein-packed without heaviness. I’ve tried cream alone, but this combo feels lighter and more balanced.
• Multitask wisely: While the soup simmers, prep the grilled cheese croutons so they’re fresh and crispy at serving time—it’s all about timing!

One lesson I learned the hard way: overheating the soup after adding dairy can cause it to break or curdle. Keep the heat low and stir gently when warming through.

Variations & Adaptations

This recipe adapts well to different tastes and dietary needs, so don’t hesitate to experiment:

• Vegan version: Use coconut milk or cashew cream instead of dairy cream, and swap cottage cheese with blended silken tofu or cashew cream. Use vegan cheese or omit grilled cheese croutons altogether, topping with toasted seasoned breadcrumbs instead.
• Spicy kick: Add a pinch of crushed red pepper flakes when sautéing onions or swirl in some harissa paste into the soup before blending for a smoky heat.
• Seasonal twist: Swap fresh basil for fresh thyme or oregano in cooler months, and add a pinch of smoked paprika for a deeper flavor profile.
• Gluten-free: Use gluten-free bread for the grilled cheese croutons and verify broth ingredients.
• Personal favorite: Once, I stirred in a spoonful of pesto into the soup right before serving, which added a lovely herbaceous punch that paired beautifully with the cheddar croutons.

For a heartier meal, serve alongside a fresh arugula salad or try pairing with a creamy pasta dish like this one-pot Cajun chicken pasta that’s equally comforting and straightforward.

Serving & Storage Suggestions

This soup is best served warm, fresh from the pot, with the grilled cheese croutons added just before eating to maintain their crispness. Presentation-wise, a drizzle of olive oil or a sprinkle of finely chopped fresh basil on top adds a nice visual and flavor boost.

Pair it with a light crisp white wine or a sparkling water with lemon for a refreshing contrast. For a fuller meal, a side salad or roasted vegetables complement the creamy tomato flavors beautifully.

To store, keep the soup in an airtight container in the refrigerator for up to 3 days. The grilled cheese croutons are best made fresh but can be kept separately in an airtight container for 1 day. Reheat the soup gently on the stove or microwave, adding a splash of broth if it thickens too much.

Reheat croutons in a 350°F (175°C) oven for 5-7 minutes to bring back their crisp texture. The soup flavors tend to deepen overnight, making leftovers even more satisfying.
