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, and the fresh basil really brightens it up. Here’s what you’ll need:

• For the Soup:
• 3 pounds (1.4 kg) ripe Roma tomatoes, halved (the star of the show—look for firm, meaty tomatoes)
• 1 whole head of garlic, halved horizontally (roasted to mellow its bite)
• 3 tablespoons olive oil (I recommend California Olive Ranch for a buttery finish)
• 1 medium yellow onion, roughly chopped (adds depth and sweetness)
• 2 cups (480 ml) vegetable broth (homemade or low-sodium store-bought works great)
• 1 cup (240 ml) heavy cream or coconut cream for dairy-free option (adds that creamy silkiness)
• 1/2 cup (freshly packed) basil leaves, roughly chopped (fresh is best, but frozen works in a pinch)
• Salt and freshly ground black pepper to taste
• 1 teaspoon sugar (optional, to cut acidity if needed)
• For the Toasted Croutons:
• 4 slices of rustic bread or sourdough, cut into 1-inch cubes (day-old bread is perfect)
• 2 tablespoons unsalted butter, melted (or olive oil for a vegan twist)
• 1 teaspoon garlic powder (for that extra punch)
• Salt and pepper to taste
• Fresh herbs like parsley or thyme (optional garnish)

Feel free to swap the heavy cream with Greek yogurt for a tangier twist or use almond milk mixed with a tablespoon of cornstarch if you want a lighter version. For a gluten-free option, make sure your bread is certified gluten-free or skip the croutons altogether.

Equipment Needed

• A large baking sheet for roasting the tomatoes and garlic (I use a rimmed sheet to catch all the juice and caramelization)
• A sharp chef’s knife (trustworthy knives make all the difference here)
• A large pot or Dutch oven to cook the soup and blend the flavors
• Immersion blender or a countertop blender (an immersion blender makes for easy, less messy pureeing)
• Mixing bowl for tossing croutons
• Measuring cups and spoons for accuracy (especially helpful for seasoning)
• Optional: Fine mesh strainer if you want the ultimate smooth texture (I do this sometimes, but it’s not necessary)

If you don’t have a Dutch oven, a heavy-bottomed pot works fine. For toasting croutons, a skillet is handy if you prefer stovetop method instead of oven baking. I’ve found that using quality tools really speeds things up and helps you get consistent results.

Preparation Method

1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease it.
2. Prepare the tomatoes and garlic: Toss halved Roma tomatoes and the halved garlic head with 3 tablespoons of olive oil, salt, and pepper. Spread them cut-side up on the baking sheet. Roast for 35-40 minutes until tomatoes are soft and slightly caramelized, and garlic is tender.
3. While the tomatoes roast, prepare the croutons: In a mixing bowl, toss bread cubes with melted butter, garlic powder, salt, and pepper. Spread on a separate baking sheet in a single layer. Toast in the oven for 10-12 minutes, flipping halfway through, until golden and crispy.
4. Sauté onions: In a large pot or Dutch oven, heat a little olive oil over medium heat. Add chopped onions and cook for 5-7 minutes until soft and translucent. Season lightly with salt to help them sweat.
5. Add roasted tomatoes and garlic: Once roasted, squeeze the garlic cloves out of their skins and add to the pot along with the tomatoes and any juices from the roasting pan.
6. Pour in vegetable broth: Add 2 cups (480 ml) of broth to the pot. Bring to a simmer and cook for 10 minutes to let flavors meld together. Taste and add sugar if the soup tastes too acidic.
7. Blend the soup: Use an immersion blender to puree the soup until smooth and creamy. If using a countertop blender, blend in batches and be careful with hot liquids.
8. Finish with cream and basil: Stir in 1 cup (240 ml) heavy cream and fresh basil leaves. Heat gently for 2-3 minutes without boiling to keep the cream from curdling. Adjust salt and pepper to taste.
9. Serve hot: Ladle soup into bowls, garnish with toasted croutons and a few fresh basil leaves if desired.

Pro tip: If your soup feels a little thick, loosen it with a splash more broth or cream. The roasted garlic is subtle but adds a warm, mellow depth—don’t skip it!

Cooking Tips & Techniques

Roasting is the secret weapon here. It concentrates the tomatoes’ natural sweetness and adds a smoky depth that canned tomatoes just can’t match. Don’t rush this step; those caramelized edges are where the magic lives.

When blending hot soup, always remove the center cap of your blender lid and cover with a kitchen towel to let steam escape safely. I learned the hard way when my kitchen got a tomatoey explosion!

For the croutons, tossing them with butter and garlic powder before toasting gives a rich, savory crunch. If you want more garlic punch, sprinkle finely minced fresh garlic on the bread before baking—but watch carefully so it doesn’t burn.

Timing matters: roast your tomatoes and garlic first, then prep your onions while they cook. Multitasking here saves you precious minutes and keeps the kitchen workflow smooth.

Lastly, always taste and adjust seasonings at the end. Sometimes a pinch of sugar balances the acidity, or a little extra basil brightens the whole bowl. Cooking is part art, part science, and a bit of soul.

Variations & Adaptations

• Dairy-Free Version: Swap heavy cream for coconut cream or almond milk thickened with a teaspoon of cornstarch for a creamy but vegan-friendly soup.
• Spicy Kick: Add a pinch of red chili flakes while sautéing onions or swirl in some harissa paste at the end for a smoky heat.
• Herb Swap: Try fresh oregano or thyme instead of basil for a different herbal note. Rosemary also works well if used sparingly.
• Slow Cooker Method: Roast tomatoes and garlic, then transfer everything to a slow cooker with onions and broth. Cook on low for 4 hours. Blend and add cream at the end.
• Personal Twist: I once added roasted red bell peppers for extra sweetness and a vibrant color—it was a hit with my kids who usually shy away from tomato soup!

Serving & Storage Suggestions

This soup is best served hot, fresh from the stove, with those toasted croutons adding a satisfying crunch. A drizzle of extra virgin olive oil or a sprinkle of grated Parmesan cheese on top turns it into a restaurant-worthy starter.

Pair it with a crisp green salad or a grilled cheese sandwich for a classic combo that never disappoints. A chilled glass of Sauvignon Blanc or a light herbal tea also complements the fresh basil notes beautifully.

Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight—honestly, sometimes it tastes even better the next day. Reheat gently on the stove over low heat, stirring occasionally, to keep the cream from separating.

You can freeze the soup (without croutons) for up to 2 months. Thaw overnight in the fridge and reheat slowly. Toast fresh croutons just before serving to keep them crispy.

FAQs

Can I use canned tomatoes instead of fresh for this soup?

Yes, you can! Use about 3 cans (14.5 oz / 411 g each) of whole peeled tomatoes, drain most of the liquid, and roast them with garlic for a similar flavor. Fresh tomatoes do offer a brighter taste, though.

How do I store leftover soup and croutons?

Store soup in an airtight container in the fridge for up to 3 days. Croutons keep best in a sealed bag or container at room temperature for 2-3 days to stay crispy.

Can I make this soup ahead of time?

Absolutely! It tastes even better the next day after the flavors meld. Just reheat gently and add fresh croutons before serving.

What can I substitute for heavy cream?

Coconut cream or full-fat coconut milk is a great dairy-free alternative. You can also use Greek yogurt stirred in at the end, but add it off the heat to avoid curdling.

How do I make gluten-free croutons?

Use gluten-free bread cubes tossed with olive oil and seasoning, then bake until crispy. Or skip the croutons and add a sprinkle of toasted nuts or seeds for crunch.
