15 oz can tomato sauce: Enhances the depth and smoothness of the soup’s texture.

1 medium yellow onion (diced): Provides a mild sweetness and foundational aroma when cooked down.
2 – 3 cloves garlic (minced): Adds a gentle but essential savory kick.
1/4 cup chopped fresh basil: The star herb that brings fresh, peppery brightness.
1 tsp kosher salt: Balances and enhances all the flavors.
1/2 tsp black pepper: Gives a subtle hint of warmth.
4 cups reduced sodium chicken broth: Creates a savory and well-rounded soup base.
3 Tbsp unsalted or salted butter: Used in the roux to add creaminess and richness.
3 Tbsp all-purpose flour: Thickens the soup smoothly without clumps.
12 oz can evaporated milk: Brings creaminess while keeping the soup light.
1 cup heavy cream: Makes the soup luxuriously smooth and silky.
1 1/2 cups grated Parmesan cheese: Freshly grated Parmesan adds a wonderful savory depth and slight nuttiness.

How to Make Creamy Tomato Basil Soup Recipe

Step 1: Combine and Slow Cook

Start by adding the diced tomatoes with their juices, tomato sauce, tomato paste, onion, garlic, fresh basil, kosher salt, black pepper, and chicken broth to your slow cooker. Give it all a good whisk or stir to combine those flavors beautifully. Cover and let it cook on LOW for 6-8 hours or on HIGH for 3-4 hours. This slow simmer not only melds the flavors together but also softens the tomatoes and onions perfectly, building a deep, comforting base.

Step 2: Blend Until Smooth

About 40 minutes before serving, use an immersion blender directly in the slow cooker or carefully transfer the soup in batches into a regular blender. Blend until the texture is silky smooth. If you use a traditional blender, be sure to pour the soup back into the slow cooker afterward so you can finish it off right there.

Step 3: Prepare the Creamy Roux

In a small saucepan over medium heat, melt the butter. Whisk in the flour and cook for about a minute, whisking regularly to prevent lumps and to toast the flour lightly. Slowly add in the heavy cream and evaporated milk, whisking continuously until the mixture thickens slightly and becomes luscious and smooth. Finally, stir in that freshly grated Parmesan cheese until it melts into the silky sauce.

Step 4: Combine and Final Simmer

Pour the creamy Parmesan mixture into the slow cooker with your blended tomato soup and stir well to combine. Cook uncovered on HIGH for another 20 minutes or so, letting the soup thicken a little more and all the flavors marry beautifully. This step transforms the soup into a velvety masterpiece that will delight every spoonful.

Garnishes

Fresh herbs truly elevate any dish, and this soup is no exception. Sprinkle some finely minced fresh basil on top, or add a generous handful of grated Parmesan cheese for an extra savory finish. For a touch of indulgence, a small swirl of cream or a drizzle of high-quality olive oil also works wonders to make your presentation shine.

Side Dishes

A bowl of creamy tomato basil soup deserves some delicious companions. Classic grilled cheese sandwiches pair beautifully, creating that perfect nostalgic combo. Crusty bread, garlic breadsticks, or even a crisp green salad can round out your meal with texture and freshness. Plus, dipping any bread right into the soup is pure joy.

Creative Ways to Present

For a fun twist, serve the soup in hollowed-out bread bowls for a charming and edible vessel. Garnish with toasted pine nuts or a sprinkle of smoked paprika for a touch of sophistication. You could also ladle the soup over cooked grains like quinoa or rice for a hearty, warm bowl that doubles as a main dish. The possibilities to customize are endless!

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, store the soup in airtight containers in the refrigerator for up to 4 days. The flavors will continue to meld, making it even tastier the next day.

Freezing

This Creamy Tomato Basil Soup Recipe freezes beautifully. Cool the soup completely, then transfer to freezer-safe containers or heavy-duty freezer bags. It will stay fresh for up to 3 months. Keep in mind that dairy can sometimes slightly change texture after thawing, but a quick whisk or stir while reheating brings it right back.

Reheating

Reheat gently on the stovetop over medium-low heat, stirring occasionally to prevent scorching. Add a splash of milk or cream if the soup seems too thick after reheating. Avoid microwaving directly from frozen to prevent uneven heating—thaw overnight in the fridge if possible for best results.

FAQs

Can I make this soup without a slow cooker?

Absolutely! You can prepare the soup on the stovetop by simmering the tomatoes, broth, and aromatics in a large pot over medium-low heat for about an hour, stirring occasionally. Then follow the same blending and creamy roux steps for equally delicious results.

Is there a vegetarian version of this Creamy Tomato Basil Soup Recipe?

Certainly! Simply substitute the chicken broth for vegetable broth and ensure the Parmesan cheese you use is vegetarian-friendly (some Parmesan contains animal rennet). This swap keeps the soup flavorful and rich without compromising on taste.

Can I use fresh tomatoes instead of canned?

You can, though canned tomatoes offer consistency and deep flavor since they are often picked and packed at peak ripeness. If using fresh, choose ripe, juicy tomatoes, peel and chop them, and you may need to cook the soup a bit longer to soften and break them down fully.

How do I make this soup dairy-free?

To make a dairy-free version, swap the butter for a plant-based alternative, and replace evaporated milk and heavy cream with coconut milk or cashew cream. Omit the Parmesan or use a dairy-free cheese alternative. The soup will still be wonderfully creamy and comforting.

Can I add other herbs or spices to customize the flavor?

Definitely! While basil is traditional and pairs perfectly with tomatoes, adding a touch of thyme, oregano, or rosemary can add new dimensions. A pinch of red pepper flakes will add some heat, and smoked paprika can add a subtle smoky note. Just be sure not to overpower the fresh tomato and basil base.
