• 1 bag (12 oz) frozen mixed vegetables

• 8 cups vegetable stock

Notes & Substitutions

You can easily adapt this versatile recipe to fit your pantry and preferences. These tips will help you make this slow cooker soup truly your own.

• Aromatics: The combination of onion, celery, and carrots (known as mirepoix) forms the foundational flavor base for this savory soup. Feel free to use pre-chopped versions to save time.
• Potatoes: Yukon Gold potatoes hold their shape well and offer a creamy texture when cooked, making them ideal for this hearty soup. Red potatoes or even sweet potatoes could work as alternatives. Consider our creamy potato soup for another comforting option.
• Tomatoes: Fire-roasted tomatoes add a lovely smoky depth that regular diced tomatoes won’t provide. If you prefer a less smoky flavor, use plain diced tomatoes.
• Vegetables: Fresh vegetables are always wonderful, but frozen mixed vegetables are a fantastic shortcut, offering convenience and consistent quality. Feel free to add other favorites like green beans or corn.
• Herbs: Dried thyme and Italian seasoning are convenient and potent. If using fresh herbs, double the quantity for a bolder flavor.
• Broth: Vegetable stock keeps this soup vegetarian and vegan-friendly. Chicken broth is a suitable alternative if you don’t have dietary restrictions and prefer that flavor.
• Seasoning: Always taste and adjust salt and pepper at the end of cooking. Different broths can vary in sodium content.

Equipment

You won’t need many special tools for this easy slow cooker soup recipe. Your slow cooker does most of the hard work.

• Slow Cooker: A 6-quart or larger slow cooker is ideal for this recipe’s volume.
• Basic kitchen tools: A sharp knife, a cutting board, and a ladle for serving.

Instructions

Creating this comforting slow cooker soup recipe is incredibly straightforward. Just follow these simple steps, and you’ll have a delicious, warming meal ready with minimal effort.

Prep Vegetables

Begin by thoroughly washing all your fresh vegetables. Carefully peel the carrots and potatoes. Then, precisely chop the onion, celery, and carrots into roughly uniform, bite-sized pieces. Dice the peeled Yukon Gold potatoes into small, even pieces; this ensures they cook consistently and become tender at the same time as the other vegetables in your slow cooker soup recipe.

Combine Ingredients

Now, carefully transfer all the prepared vegetables – the chopped onion, celery, carrots, and diced potatoes – directly into the ceramic insert of your slow cooker. Add both cans of fire-roasted tomatoes, including their juices, and the entire bag of frozen mixed vegetables. This centralizes all the solid components for your delicious soup.

Add Liquids & Seasoning

Pour the 8 cups of vegetable stock over the vegetables in the slow cooker. Distribute the dried thyme, minced garlic, salt, pepper, and Italian seasoning evenly over the ingredients. Don’t forget to add the two bay leaves; they infuse a wonderful aromatic depth into your simmering soup as it cooks.

Gentle Stir

Using a large spoon, gently stir all the ingredients together in the slow cooker. Ensure that the vegetables are submerged as much as possible in the liquid and that the seasonings are well distributed throughout the mixture. This initial stir helps all the flavors meld together perfectly right from the start of this easy slow cooker soup recipe.

Cover & Cook

Place the lid securely on your slow cooker. Set the cooking time according to your schedule. Cook the soup on the LOW setting for 5-6 hours. If you need it sooner, cook on the HIGH setting for 2.5-3 hours. The slow cooker will do all the work, gently simmering the ingredients until tender.

Check Doneness

Around the end of the cooking time, check the potatoes for tenderness. Carefully pierce a potato piece with a fork; it should be very soft and easily mashed. If they are still firm, continue cooking for another 30 minutes to an hour, checking periodically. This ensures every bite of your slow cooker soup recipe is perfectly cooked.

Remove Bay Leaves

Before serving, use a spoon or tongs to carefully locate and remove both bay leaves from the soup. Bay leaves are used for flavor infusion and should not be consumed. Discard them once removed.

Adjust Seasoning

Taste a spoonful of the hot soup. This is your chance to fine-tune the flavors. Add more salt or pepper if desired, a pinch more Italian seasoning, or a dash of your favorite herb. Stir well after adding any additional seasoning to integrate it fully.

Serve Warm

Ladle generous portions of the hot, comforting slow cooker vegetable soup into individual bowls. Serve immediately and savor the rich flavors and tender vegetables that have developed over hours of slow cooking. Enjoy your homemade slow cooker soup recipe!

Pro Tips & Troubleshooting

These tips will help you master this slow cooker soup recipe and prevent common issues. Even beginners can achieve perfect results with a few helpful pointers.

• Uniform Chopping: Ensure all your vegetables, especially the potatoes, are chopped into similar-sized pieces. This consistency guarantees they cook evenly and become tender at the same rate.
• Don’t Overfill: Never fill your slow cooker more than two-thirds full. Overfilling can lead to uneven cooking, spills, and potentially uncooked ingredients in your slow cooker soup.
• Seasoning Check: Always taste your soup at the very end of cooking. Different brands of broth and canned tomatoes have varying sodium levels, so adjusting the seasoning before serving is crucial for optimal flavor.
• Prevent Mushiness: While slow cooking is forgiving, don’t drastically overcook your soup beyond the recommended time, especially on high. Overcooked vegetables can become mushy, losing their pleasant texture.
• Thickening Options: If your slow cooker soup recipe is thinner than you prefer, you have a few options. Mix a tablespoon of cornstarch with an equal amount of cold water to form a slurry, then stir it into the hot soup during the last 30 minutes of cooking. Alternatively, mash some of the potatoes against the side of the slow cooker to release their starch.
• Flavor Boost: For an extra layer of flavor, consider sautéing the chopped onions, celery, and carrots in a little olive oil on the stovetop for 5-7 minutes until slightly softened before adding them to the slow cooker. This caramelizes the aromatics and adds depth to the final slow cooker vegetable soup.

Serving, Storage & Variations

This versatile slow cooker soup recipe is perfect on its own, but these ideas will elevate your meal and ensure you can enjoy it for days.

Serving Suggestions

Elevate your comforting bowl of soup with simple additions.

• Serve with warm, crusty bread or rolls for dipping.
• Garnish with fresh chopped herbs like parsley, chives, or cilantro for a burst of freshness.
• Sprinkle with grated Parmesan or sharp cheddar cheese for extra savory flavor.
• Add a dollop of sour cream or plain Greek yogurt for a creamy finish.

Storage Instructions

Storing your soup properly extends its delicious life. This slow cooker soup recipe is excellent for making ahead.

• Cool Completely: Allow the soup to cool fully before transferring it to containers. This prevents condensation and keeps it fresh.
• Airtight Container: Store the cooled soup in clean, airtight containers to maintain freshness and prevent odors.
• Refrigerate: Keep refrigerated for up to 3-4 days. The flavors often deepen beautifully overnight.
• Freezing: This soup freezes exceptionally well! Transfer cooled soup to freezer-safe bags or containers, leaving some headspace. It will keep for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheating: Gently reheat on the stovetop over medium-low heat until warmed through, stirring occasionally. You can also microwave individual portions.

Recipe Variations

Get creative with your slow cooker soup recipe and tailor it to your liking.

• Add Protein: Stir in cooked lentils, canned chickpeas, or kidney beans for a heartier, plant-based meal. Cooked shredded chicken or turkey can also be added during the last 30 minutes.
• Different Vegetables: Feel free to swap or add other vegetables like fresh spinach (stir in during the last 15 minutes), corn, zucchini, or bell peppers. For an easy side, try crispy air fryer green beans.
• Spice It Up: Add a pinch of red chili flakes or a dash of your favorite hot sauce for a gentle kick.
• Creamy Version: Stir in 1/2 cup of full-fat coconut milk, heavy cream, or a dairy-free alternative during the last 30 minutes of cooking for a richer, creamier slow cooker vegetable soup.
• Herb Swaps: Experiment with different dried or fresh herbs such as rosemary, dill, or marjoram to create new flavor profiles for your slow cooker soup.
