Vegetable Soup Ingredients

  • Vegetable Stock¬†- Forms the base of the soup, adding depth and a rich, savory flavor that enhances the vegetables.
  • Mirepoix¬†(carrots, celery, onion) - Provides a classic flavor foundation, offering sweetness from the carrots, a slight bitterness from the celery, and aromatic flavor from the onions.
  • Russet Potatoes¬†- Contribute a starchy, hearty texture, thickening the soup and adding a comforting, filling element.
  • Condensed Tomato Soup¬†- Adds a smooth, rich tomato base that deepens the overall flavor profile and provides a creamy consistency.
  • Canned Diced Tomatoes¬†- Introduce a chunkier texture and a fresh tomato taste that complements the smoother condensed soup.
  • Tomato Paste¬†- Imparts a concentrated tomato flavor, deepening the soup's color and richness without adding excess liquid.
  • Minced Garlic¬†- Brings a pungent, aromatic quality that is essential in building a complex flavor base.
  • Worcestershire Sauce¬†- Provides a subtle tang and umami depth, enhancing the savory notes of the vegetables and broth.
  • Frozen Mixed Vegetables¬†- Offer convenience and variety, adding color texture with no need to prep.¬†
  • Seasonings¬†(Italian, dried rosemary, bay leaf, salt, pepper) - These herbs and spices collectively build a warm, aromatic profile that complements and enhances the natural flavors of the vegetables.
  • Bay Leaf¬†- Adds a subtle layer of depth and aroma, infusing the soup with a distinctive, slightly floral flavor.

How To Make Vegetable Soup In The Crock Pot

Add the ingredients: Once the vegetables are chopped and ready, add them to the bottom of a 6-quart slow cooker along with the stock, canned tomato elements, seasonings, and sauces. Place everything into the crock pot EXCEPT the bag of frozen vegetables. 

Cover and cook: Add the lid to the top and cook on HIGH for 3-4 hours or LOW for 5-6 hours. The potatoes should be cooked through and fork tender, and the raw tomato flavor should be cooked out. 

Add frozen vegetables: 30 minutes before the end of the cooking time, pour in the frozen vegetables and stir them into the mixture. Cook for 30 minutes or until the vegetables are thawed and the soup has warmed back up. 

Serve and enjoy: Remove the bay leaf from the soup. Ladle into bowls while hot. Enjoy! 

Recipe Tips

  • Saut√© your mirepoix (carrots, celery, onion) before adding to the crock pot to deepen their flavors and add a caramelized note to the soup.
  • If you have time, rinse the russet potatoes after cutting to remove excess starch, ensuring they contribute to the soup's thickness without making it overly starchy.
  • Use low-sodium vegetable stock to control the overall saltiness of the dish, allowing you to adjust seasonings to your preference.
  • Incorporate the frozen mixed vegetables in the last 30 minutes of cooking to maintain their texture and vibrant color.
  • If the soup is too thick after cooking, thin it with a little extra vegetable stock or water until you reach your desired consistency.
  • For a smoother soup, blend a portion of it with a blender or immersion blender after cooking and then mix it back in for a creamier texture.

Flavor Variations and Substitutions

  • For a heartier¬†beef vegetable soup¬†version, brown ground beef and drain the fat before adding it to the crock pot, infusing the soup with rich, meaty flavors.
  • Stir in chopped cabbage during the last hour of cooking for a comforting, subtly sweet addition that complements the other vegetables.
  • Incorporate chunks of browned stew meat for a robust, beefy element that turns the vegetable soup into a more substantial stew.
  • Swirl in some heavy cream or coconut milk in the last few minutes of cooking for a creamy twist on the classic recipe.
  • Replace russet potatoes with sweet potatoes to add a slightly sweet, earthy flavor and boost the nutritional content even more.
  • Introduce a handful of fresh spinach or kale at the end of cooking for added color, texture, and a nutritional boost.
  • Add a splash of balsamic vinegar or lemon juice just before serving to brighten the soup with a tangy note.
  • Mix in some cooked quinoa or rice to turn the soup into a more filling, comforting meal with added texture.

Storing & Freezing

Storing: Place any leftover vegetable soup in an airtight container and refrigerate within two hours of cooking. It will stay fresh and flavorful for up to 5 days.

Freezing: Cool the soup completely before transferring it to freezer-safe bags or containers, leaving some space for expansion. Label with the date; it will keep well for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating: Warm the soup on the stove over medium heat, stirring occasionally, until it's heated through. If it's too thick, add a bit of water or vegetable stock to reach your desired consistency.
