Ingredients
Instructions
1. 1. Saute the aromatics (optional but recommended): In a large skillet, heat the olive oil over medium heat. Add the chopped onion, carrots, and celery. Saute for 5-7 minutes until softened. Stir in the minced garlic and cook for another minute until fragrant. This step helps to build a deeper flavor base for your soup.
2. 2. Combine ingredients in the slow cooker: Transfer the sauteed vegetables (if you did step 1) or the raw chopped onion, carrots, and celery directly into your slow cooker. Add the crushed tomatoes, diced tomatoes (undrained), vegetable broth, dried oregano, dried basil, black pepper, and bay leaf. Stir everything gently to combine.
3. 3. Set and forget: Cover the slow cooker and cook on low for 6-8 hours or on high for 4-6 hours. The longer cooking time on low often results in a more developed flavor, but high works perfectly if you’re short on time.
4. 4. Add remaining vegetables and pasta: About 30-60 minutes before serving, stir in the chopped green beans, corn kernels, and frozen peas. If you’re adding pasta, stir it in now as well. The pasta will cook directly in the soup, absorbing the delicious broth.
5. 5. Check for doneness and season: Continue cooking until the vegetables are tender and the pasta (if using) is cooked through. Carefully remove the bay leaf. Taste the soup and add salt as needed. Remember that broth can vary in sodium content, so always taste before adding too much salt.
6. 6. Serve warm: Ladle the hot soup into bowls. Garnish with fresh chopped parsley, if desired, for a pop of color and fresh flavor. Serve immediately with your favorite crusty bread or crackers.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients for this slow cooker vegetable soup is straightforward. Most items are pantry staples or easily found at any grocery store. The beauty of this recipe lies in its simplicity and the readily available nature of its components.
INGREDIENTS:

- 1 tablespoon olive oil
- 1 large onion, chopped
- 2 carrots, peeled and diced
- 2 celery stalks, diced
- 2 cloves garlic, minced
- 1 (28 ounce) can crushed tomatoes
- 1 (15 ounce) can diced tomatoes, undrained
- 4 cups vegetable broth
- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil
- 1/4 teaspoon black pepper
- 1 bay leaf
- 1 cup chopped green beans (fresh or frozen)
- 1 cup corn kernels (fresh or frozen)
- 1 cup frozen peas
- 1/2 cup small pasta (like ditalini or elbow macaroni), optional
- Salt to taste
- Fresh parsley, chopped, for garnish (optional)
When it comes to substitutions, this recipe is incredibly flexible. If you don’t have fresh carrots, frozen mixed vegetables that include carrots work just fine. You can swap out green beans for zucchini or yellow squash if you prefer, adding them in the last hour of cooking to prevent them from getting too soft. For the broth, chicken broth can be used if you’re not strictly vegetarian. Feel free to use your favorite blend of dried herbs if oregano and basil aren’t your top choices; Italian seasoning is a great alternative. If you want to make it heartier without adding meat, a can of rinsed and drained cannellini beans or chickpeas can be stirred in during the last hour.

Making this slow cooker vegetable soup is incredibly simple. Follow these steps for a delicious and comforting meal.

Easy Variations And Serving Ideas That Fit Real Life
This slow cooker vegetable soup is wonderfully versatile, allowing for many adaptations to suit different tastes and occasions.
For kid-friendly appeal, you can blend a portion of the soup before adding the final vegetables and pasta. This creates a smoother texture that some children prefer, while still retaining all the nutrients. You can also add fun shapes of pasta to make it more appealing. Another idea is to serve it with grilled cheese “dippers” – small strips of grilled cheese sandwiches perfect for dunking.
To make it heartier, consider adding cooked shredded chicken or turkey during the last hour of cooking. A can of drained and rinsed cannellini beans, kidney beans, or chickpeas also adds protein and fiber. For a touch of creaminess, stir in a splash of heavy cream or a dollop of plain Greek yogurt just before serving.
When serving, a sprinkle of grated Parmesan cheese or a swirl of pesto can elevate the flavor profile. Freshly baked crusty bread, garlic bread, or even cornbread are excellent accompaniments for soaking up the delicious broth. For a light lunch, pair it with a simple side salad. For a buffet or party, keep the soup warm in the slow cooker on the “warm” setting and provide a variety of toppings like shredded cheese, croutons, and fresh herbs for guests to customize their bowls.
Common Slip-Ups And How To Avoid Them
Even with a simple recipe like slow cooker vegetable soup, a few common mistakes can impact the final result. Knowing how to avoid them will ensure your soup turns out perfectly every time.
One frequent error is overcooking the delicate vegetables. While root vegetables like carrots and celery can withstand long cooking times, softer vegetables like green beans, corn, and especially peas can become mushy if added too early. To prevent this, always add these quicker-cooking vegetables during the last 30-60 minutes of the cooking cycle. This ensures they retain their texture and vibrant color.
Another common oversight is not seasoning adequately. Slow cooking can sometimes mellow out flavors, so it’s crucial to taste the soup before serving and adjust the salt and pepper as needed. Don’t be afraid to add a little more dried herbs or even a pinch of red pepper flakes for a subtle kick if you feel it needs more depth.
Forgetting to sauté the aromatics (onion, carrots, celery, garlic) at the beginning is another miss. While not strictly mandatory, this step, known as building a “mirepoix,” significantly deepens the flavor of the soup. Sautéing them first caramelizes their natural sugars and releases their aromatic compounds, leading to a richer, more complex broth. If you skip this, your soup might taste a bit flatter.
Finally, adding too much liquid or not enough can affect the consistency. Stick to the recommended amount of broth. If you find your soup is too thick at the end, you can always add a little more hot vegetable broth or water until it reaches your desired consistency. Conversely, if it’s too thin, you can let it simmer uncovered on high for a short period to allow some liquid to evaporate, or stir in a tablespoon of cornstarch mixed with a little cold water to thicken it slightly.
How To Store It And Make It Ahead Without Ruining Texture
This slow cooker vegetable soup is fantastic for meal prepping and makes excellent leftovers. Proper storage ensures you can enjoy its comforting flavors for days.
To store, allow the soup to cool completely to room temperature before transferring it to airtight containers. Refrigerate promptly within two hours of cooking. Stored in the refrigerator, the soup will stay fresh for 3-4 days. The flavors often meld and deepen overnight, making it even more delicious the next day.
For longer storage, this soup freezes beautifully. Once cooled, ladle the soup into freezer-safe containers or heavy
