Ingredients You’ll Need

9 Roma tomatoes, sliced lengthwise
3 tbsp extra virgin olive oil
2 tbsp unsalted butter
1 yellow onion, diced
4 garlic cloves, minced
1 tbsp fresh thyme, minced
1 tsp Kosher salt
½ tsp ground black pepper
1 × 28 oz can San Marzano tomatoes, crushed
1 cup fresh basil, roughly chopped
1 tbsp sugar
2 cups chicken stock (or vegetable stock for a vegetarian option)
⅔ cup heavy cream

Optional croutons: cubed bread tossed with olive oil, garlic, and basil, baked at 400°F for 7 minutes.

Step-by-Step Instructions

Roast the tomatoes: Preheat oven to 375°F. Arrange Roma tomatoes on a baking sheet, drizzle with olive oil, and sprinkle with salt and pepper. Roast for 1 hour until soft and caramelized.
Sauté the aromatics: In a Dutch oven, melt butter over medium-high heat. Add onion, cooking for 5 minutes until translucent. Stir in garlic, thyme, salt, and pepper. Cook for 1 minute.

Build the flavor: Add crushed San Marzano tomatoes, basil, and sugar. Simmer for 10 minutes on low heat.
Bring it all together: Stir in roasted tomatoes and chicken stock. Let it simmer for 30 minutes, stirring occasionally.
Blend it smooth: Use an immersion blender (or carefully transfer to a blender) to purée until creamy.

Add the finishing touch: Stir in heavy cream and let it simmer for 2–3 minutes.
Serve: Ladle into bowls, top with croutons if you’re feeling fancy, and enjoy.

Helpful Cooking Tips

Roasting is key. Don’t skip roasting the Roma tomatoes—it’s what gives this soup its depth and sweetness.

Make it vegetarian. Simply swap chicken stock for vegetable stock, and you’ve got a homemade basil soup that’s vegetarian-friendly.
Cream control. For a lighter soup, reduce the cream to half. Or, for an extra indulgent bowl, add an extra splash. No judgment here.
Don’t panic about lumps. If your soup looks a little rustic before blending, that’s normal. Once puréed, it transforms into silky perfection.

Double up. This recipe freezes beautifully, so consider making a double batch and tucking some away for a future lazy day.

A Little Story from My Kitchen

The very first time I made this roasted tomato recipe, it was after one of those “nothing’s going right” days—you know the ones. I had a bunch of Roma tomatoes sitting on the counter, begging to be used, and I decided to roast them just to see what would happen. Thirty minutes later, the kitchen smelled like a cozy Italian trattoria, and I thought, “This could be something.”

I added basil from my little windowsill plant, a splash of cream, and—voilà—my family had their new favorite soup. My kids, who are usually suspicious of anything green, went back for seconds. That’s when I knew this recipe was a keeper. It’s been my go-to for family nights, snow days, and even a quick dinner with friends ever since.

What to Serve with Roasted Tomato Basil Soup

This cozy winter soup is a meal in itself, but pairing it can turn it into a feast. Of course, the classic grilled cheese sandwich is a no-brainer—crispy, golden bread hugging gooey melted cheese, dunked straight into your soup bowl. Heaven!

For a lighter side, try a crisp Caesar salad or a simple arugula salad with lemon vinaigrette. Crusty artisan bread or homemade garlic bread is another win (because bread + soup = happiness). And if you’re entertaining, serve it in small cups as an appetizer before a main course like roasted chicken or pasta.

The beauty of this soup is its versatility—it plays well with simple comfort food and with fancier dishes.

How to Store Your Soup

Refrigerate: Let the soup cool completely, then store in an airtight container for up to 4 days.

Freeze: Portion into freezer-safe containers or bags. Lay flat for easy storage. Keeps well for up to 3 months.
Reheat: Warm gently on the stovetop over medium heat, stirring occasionally. If the soup thickens too much, add a splash of broth or cream.

Pro tip: Freeze in single-serving portions so you can grab just what you need—perfect for those “me time” lunches.

FAQs

Can I substitute canned tomatoes for fresh?

Absolutely! Fresh roasted tomatoes give a rich depth, but canned San Marzano tomatoes work beautifully in a pinch.

Can I make this creamy tomato soup dairy-free?

Yes—skip the heavy cream and swap in coconut cream or cashew cream. You’ll still get that luscious texture.

What if I don’t have fresh basil?

Dried basil works too, but fresh really elevates this homemade basil soup. If using dried, add it earlier in the cooking process for maximum flavor.

Can I use an Instant Pot?

Yes! Sauté your onions, garlic, and herbs first, then add everything in and pressure cook for 15 minutes. Blend and finish with cream.
