Ingredients You’ll Need

Inside a large black pot, there is a base layer of finely chopped cooked onions that appear soft and translucent. On top of the onions, there are three small piles: one of minced white garlic, one of red tomato paste with a smooth thick texture, and one of mixed dry herbs in a greenish-brown tone with a powdery look. The pot sits on a white marbled surface, and the scene is brightly lit, showing the textures clearly. photo taken with an iphone --ar 4:5 --v 7

These ingredients are wonderfully straightforward, yet each one plays a crucial role in creating a vibrant, flavorful soup. From the creamy texture lent by avocado oil and optional vegan cream to the aromatic spices and fresh herbs, everything comes together in harmony to make this recipe truly special.

3 tablespoons avocado oil: Provides a subtle fruity flavor and a healthy fat base for sautéing your veggies.
1 large sweet onion, finely chopped: Adds natural sweetness and depth when caramelized gently.
1 tablespoon fine salt: Enhances every flavor and helps soften the onion perfectly during sautéing.
1 head of garlic (about 10 cloves), minced: Infuses the soup with a warm, fragrant base note that’s irresistible.
1 tablespoon tomato paste: Concentrates the tomato flavor, adding richness and a subtle sweetness.
1 tablespoon Italian seasoning: A perfect blend of herbs that adds an earthy, aromatic complexity.
32 ounces marinara sauce (I prefer Rao’s marinara): Anchors the soup with a robust tomato base, bringing both acidity and savoriness.
½ cup long grain brown rice: Brings wholesome texture and makes the soup filling and nutritious.
8 cups filtered water: The liquid that lets everything cook slowly into a beautifully melded soup.
Optional: 12 ounces cherry tomatoes: Adds bursts of freshness and a delicate sweetness that brighten every bite.
Optional: 1 batch vegan heavy cream: For that luscious, creamy finish that makes every spoonful indulgent.
2 large handfuls fresh basil leaves, finely chopped: A fragrant herb that lifts the soup with its bright, peppery notes.

How to Make One-Pot Creamy Tomato Rice Soup Recipe

Step 1: Sauté the Onion

Start by heating the avocado oil in a large dutch oven over medium heat. Toss in your finely chopped sweet onion and sprinkle with salt. Patience is key here—sauté the onion slowly for about 10 minutes, stirring frequently. You want the onions to soften fully and just begin to caramelize, developing their natural sweetness without any burnt bits. The result is a flavorful foundation that will make your soup sing.

Step 2: Add Garlic, Tomato Paste, and Italian Seasoning

Lower the heat to keep things gentle, then stir in the minced garlic and Italian seasoning. Cooking these together for about 5 minutes allows the garlic to soften and aromatics to bloom without browning, which can introduce bitterness. The tomato paste blends in here, releasing its robust, tangy character that deepens the base flavor.

Step 3: Combine Marinara, Rice, Water, and Optional Ingredients

Next, pour in the marinara sauce, followed by the brown rice and filtered water. If you’re using cherry tomatoes and vegan cream, add those now as well. Stir everything together so all ingredients are well combined. Then, bring the soup to a gentle boil. Once boiling, cover your pot and reduce heat to low, letting it simmer for 30 to 40 minutes. This slow simmer is where magic happens: the rice cooks through, absorbing the rich tomato broth and cream, turning the mixture into a luscious, hearty soup.

Step 4: Finish with Fresh Basil

When the rice is tender and the soup has thickened nicely, turn off the heat. Stir in the finely chopped fresh basil leaves to infuse the soup with vibrant herbal brightness. Serve hot, enjoying the warmth and satisfying flavors that only this One-Pot Creamy Tomato Rice Soup Recipe can deliver.

Garnishes

A sprinkle of freshly cracked black pepper, a drizzle of extra virgin olive oil, or a scattering of Parmesan cheese (or vegan alternative) elevates this soup wonderfully. The fresh basil garnish you add at the end is essential for that burst of color and freshness, balancing out the creamy richness beautifully.

Side Dishes

This soup pairs effortlessly with crusty bread or garlic knots that are perfect for soaking up every last bit of broth. A light, crisp green salad on the side also complements the soup’s richness with refreshing crunch and acidity, making your meal more balanced and satisfying.

Creative Ways to Present

For a fun twist, try serving this soup in small bread bowls or hollowed-out tomatoes if you’re using cherry tomatoes. You can also blend a portion of the soup smooth before adding remaining rice for a unique layered texture. A sprinkle of toasted pine nuts or a swirl of pesto on top provides a gourmet touch that delights your guests.

Make Ahead and Storage

Storing Leftovers

This One-Pot Creamy Tomato Rice Soup Recipe actually tastes even better the next day as the flavors continue to meld. Store leftovers in an airtight container in the refrigerator for up to 4 days. Be sure to cool it completely before refrigerating to maintain freshness and texture.

Freezing

You can absolutely freeze this soup if you want to stock up. Transfer cooled soup into freezer-safe containers or bags, leaving some space for expansion. It keeps nicely for up to 3 months. Just note that the rice may absorb excess liquid during freezing, so expect a thicker soup once thawed.

Reheating

Reheat gently on the stovetop over medium-low heat, stirring occasionally to prevent the rice from sticking to the pot. Add a splash of water or broth if the soup becomes too thick. Microwaving works too—just cover your bowl and heat in 1-2 minute intervals, stirring in between for even warmth.

FAQs

Can I use white rice instead of brown rice in this recipe?

Absolutely! White rice cooks faster, so reduce the simmer time accordingly, usually to about 20 minutes. Just keep an eye on the texture so it doesn’t get too soft.

Is this soup gluten-free?

Yes, all the ingredients in this One-Pot Creamy Tomato Rice Soup Recipe are naturally gluten-free. Just be sure your marinara sauce doesn’t contain any hidden gluten ingredients.

Can I make this recipe vegan?

Definitely! This recipe is vegan by default if you use a vegan heavy cream option or omit it altogether. It’s a wonderful plant-based comfort meal.

How can I make this soup spicier?

Add a pinch of red pepper flakes during the garlic and seasoning step or a dash of hot sauce when serving. Both add a lovely kick without overpowering the tomato richness.

What can I substitute for avocado oil?

Olive oil is a fantastic alternative that adds a fruity depth while still being healthy for sautéing the onions and garlic.
