Slow Cooker Vegetable Soup Recipe

There’s nothing quite as comforting as a bowl of vegetable soup on a chilly day. When the aroma of simmering veggies, herbs, and spices fills the air, it’s a nostalgic reminder of family gatherings and homely warmth. This Slow Cooker Vegetable Soup gives off that amazing smell we all love, but also adds a healthful, hearty meal that’s both vegetarian and gluten-free, and delicious! The best part of all this is that the slow cooker does most of the work! Because, the key to a good soup is a long and slow simmer, and that is where our Crock Pot comes in very handy. The slow simmer gives veggies time to infuse and meld together to create a soup with plenty of flavor, plus quarts of leftover soup to pack for lunches or put away in the freezer.

Directions For Slow Cooker Vegetable Soup

1. Saute: First, start with sautéing the onions, carrots, and celery with some garlic; then, transfer them to the pot of your slow cooker.
2. Mix In: Add potatoes, tomatoes, tomato paste, green beans, herbs, spices and broth to the slow cooker; stir everything together.
3. Cook: Cover and set the Slow Cooker on LOW for 6 hours, or set it on HIGH for 3 hours.
4. Finish: Stir in some corn the last 30 minutes of cooking, and you’re pretty much DONE!

Instant Pot Vegetable Soup Directions

1. Use the sauté function to sauté onions, carrots, and celery.
2. Add the rest of the ingredients to the IP, except for corn.
3. Close the lid, set the valve to sealing, and pressure cook on high for 15 minutes. Allow a natural release for 10 minutes, then quick release.
4. Stir in the corn and let it simmer on sauté mode for a few minutes or until heated through.

Stovetop Directions

1. In a large pot, heat olive oil and sauté the onions, carrots, and celery.
2. Add the remaining ingredients, except for corn, and bring to a boil.
3. Reduce the heat, cover, and simmer for about 40 minutes or until the veggies are tender.
4. Stir in the corn and simmer for an additional 10 minutes.

Tips For Making The Best Vegetable Soup

• Frozen Veggies: I almost always use frozen green beans and frozen corn for this soup. It’s just easier for me because I have numerous bags of frozen veggies in the freezer. Thus, do not be afraid to use frozen veggies. Just dump them in the slow cooker and go about your business. 
• Deglazing: After sautéing the veggies, deglaze the pot with a splash of white wine or vegetable broth. This process will lift the flavorful bits from the bottom of the pan, adding more depth to your soup.
• Flavor Boost: The key to a flavorful soup is adding fresh herbs and acid just before serving. For this soup, stir in chopped fresh parsley or dill and add a squeeze of lemon juice.
• Make it Hearty: While I serve this Vegetable Soup as a starter, stir in some leftover shredded chicken before reheating to make this more of a main dish. Or have chicken on the side served over brown rice pilaf.
• Broth Variety: Use a mix of vegetable and chicken broth for a different flavor profile.
• Fresh Herbs: In addition to parsley and dill, add fresh rosemary, tarragon, or cilantro.
• Spice It Up: For a bit of heat, add red pepper flakes, a dash of cayenne, or sliced jalapeños.
• Salt & Pepper To Taste: If the soup tastes bland or lacks depth, add a bit more salt. If it needs a little kick or warmth, add more pepper. Everyone’s taste preference is unique. What’s perfectly seasoned for one person might be too salty or too bland for another. Trust your own palate and season the soup to what tastes best to you. The rule of thumb is to add 1 teaspoon of table salt per 1 quart (4 cups) for soups and sauces.

What To Serve With Vegetable Soup

• Crusty Bread: A fresh loaf of my rosemary garlic no-knead skillet bread is perfect for dipping and soaking up the flavorful broth.
• Grilled Cheese Sandwich: Try my ham and apple grilled cheese sandwiches for a comforting classic.
• Salads: A light mixed greens or this chef salad can provide a crunchy contrast to the soup’s texture.
• Quiche: A slice of spinach quiche pairs nicely with soup.
• Savory Muffins: Think cornbread muffins, cheese muffins, or even herb-infused muffins.

How Long Can You Keep Homemade Vegetable Soup In The Refrigerator?

• Store leftover Vegetable Soup in airtight containers and keep in the fridge for 4 to 5 days.

How To Freeze Vegetable Soup

• Transfer completely cooled soup to quart-size or gallon-size freezer bags. Seal and place the bags on a cookie sheet in one single layer; freeze.
• Once frozen, remove from cookie sheet and just stack them up in the freezer. Keep in the freezer for up to 4 months.
