Ingredients
- 1 can (28 oz) crushed tomatoes
Crushed tomatoes serve as the base of the soup, imparting a rich flavor and vibrant color. They offer a natural sweetness that balances the other savory components, providing a depth that makes the soup truly comforting. - 4 cups vegetable broth
Vegetable broth adds a savory liquid base that enhances the tomato's flavor. Using broth instead of water ensures that the soup is packed with umami and adds complexity to every bite. - 1 cup frozen cheese tortellini
The cheese tortellini contributes a delightful chewiness and creamy texture, which enhances the soup's comfort factor. As it cooks, the tortellini soaks up the soup's flavors, making each piece a mini explosion of taste. - 1 medium onion, diced
Onions bring sweetness and aromatic qualities to the dish, creating a base layer of flavor. When heated, they soften and add a savory richness that penetrates the entire soup. - 3 cloves garlic, minced
Garlic delivers a powerful punch of flavor that complements the tomatoes beautifully. Its aromatic profile adds a fragrant dimension to the soup, balancing the sweetness of the tomatoes and the richness of the tortellini. - 1 teaspoon dried oregano
Dried oregano serves as a classic Italian herb that enhances the soup's overall flavor. Its warm, earthy notes deepen the taste, while also marrying well with the tomatoes and broth. - 1 teaspoon dried basil
Basil adds a fresh, slightly sweet aroma that lifts the entire dish. It’s a traditional pairing with tomatoes, bringing out their natural flavor and adding a refreshing finish. - Salt and black pepper to taste
Seasoning is crucial in elevating the flavors of any dish. Salt enhances the natural flavors, while black pepper adds a subtle heat that rounds out the soup, ensuring a balanced taste. - 1 cup fresh spinach, chopped
Fresh spinach not only adds a vibrant color but also boosts the nutritional profile of the soup. As it wilts in the warmth, it contributes a mild earthy flavor that complements the other ingredients. - Grated Parmesan cheese, for serving
Topping the soup with grated Parmesan adds a nutty, salty flavor that enriches every bowl. The cheese melts slightly into the hot soup, creating a creamy texture and enhancing its overall indulgence.
Directions & Preparation
Step 1: Prepare the vegetables.
Start by dicing the onion and mincing the garlic. This step is essential as it creates the aromatic base for your soup. Sautéing the onion and garlic on the stovetop first can deepen their flavors, but if you prefer to skip this, you can add them directly to the slow cooker for a more straightforward approach.
Step 2: Combine the base ingredients.
In the slow cooker, combine the crushed tomatoes, vegetable broth, diced onion, and minced garlic. This blend establishes the foundation of the soup, where the acidity of the tomatoes balances with the savory broth, creating a rich and flavorful base that will permeate the entire dish.
Step 3: Add the herbs and spices.
Sprinkle in the dried oregano and basil, along with salt and pepper. This step is crucial for infusing flavor early on. As the soup cooks, the herbs will release their essential oils, permeating the broth and enriching the overall flavor, making each taste nuanced and delightful.
Step 4: Cook on low for 6-8 hours or high for 3-4 hours.
Allowing the soup to cook on low for 6 to 8 hours or on high for 3 to 4 hours is important for melding the flavors together. The slow cooking process helps the tomatoes break down and the spices to fully integrate, ensuring that each bowl has that comforting, homemade taste.
Step 5: Add tortellini and spinach.
In the final hour of cooking, add in the frozen cheese tortellini and chopped spinach. This timing ensures that the tortellini becomes tender without overcooking, while the spinach wilts perfectly, providing both nutrition and color to the dish. It's a quick addition that brightens the flavor profile of the soup.
Step 6: Serve with Parmesan cheese.
Before serving, ladle the soup into bowls and top with freshly grated Parmesan cheese. This finishing touch adds a creamy texture and enhances the soup’s overall flavor, making it comforting and rich. Each spoonful benefits from that distinct nuttiness of the cheese, adding to the rewarding dining experience.

The Depth of Tomato Flavor
The use of crushed tomatoes instead of diced or whole tomatoes in this recipe significantly impacts the soup's texture and flavor. Crushed tomatoes provide a smooth consistency that ensures a consistent flavor throughout each bowl. The natural sweetness these tomatoes bring complements the broth, making each spoonful a warming delight.
Herb Pairings and Their Role
Incorporating dried oregano and basil into the soup is not just traditional but essential for an authentic taste. These herbs add warmth and depth that enhances the tomato's flavor. The aromatic qualities of oregano, combined with the refreshing notes of basil, create a harmony that makes this soup reminiscent of a classic Italian dish.
Customization Opportunities
While this recipe provides a hearty foundation, there is ample room for customization. Feel free to add cooked proteins like shredded chicken or sausage for added heartiness. You can also experiment by adding other vegetables such as carrots or bell peppers, adjusting the soup to your preferences while still maintaining its comforting essence.
FAQs
What if my soup is too thick?
If your soup turns out thicker than desired, simply stir in additional vegetable broth or water, a little at a time, until the desired consistency is reached. This will help loosen it up while maintaining the rich flavors.
How do I ensure the tortellini is cooked properly?
Adding the tortellini during the last hour of cooking ensures they become tender but not mushy. If you're using a different type of pasta, check the package instructions for cooking times to avoid overcooking.
Can I use fresh tortellini instead of frozen?
Absolutely! If you prefer fresh tortellini, add it to the slow cooker about 30 minutes before serving since fresh tortellini cooks more quickly than frozen.
What can I do if the soup is bland?
If you find that your soup lacks flavor, try adjusting the seasoning by adding more salt, pepper, or herbs. A splash of balsamic vinegar can also enhance the overall flavor profile and bring out the sweetness of the tomatoes.
Is there a way to make this recipe heartier?
Definitely! You can add cooked protein like shredded chicken or turkey or include other vegetables such as zucchini or carrots for a more filling meal.
What if I don’t have all the herbs on hand?
In a pinch, you can use Italian seasoning as a substitute for the individual herbs. It combines basil, oregano, and other spices, providing a similar flavor profile.
Can I add beans to this soup?
Yes! Adding white beans like cannellini or kidney beans is a great way to boost fiber and protein. Just make sure to add them in the last hour of cooking if using canned beans, so they heat through without becoming mushy.
What is the best way to serve this soup?
Serve the soup hot, garnished with grated Parmesan cheese and fresh herbs. It pairs well with crusty bread or a side salad for a complete meal.
