• Cooking Method: Slow Cooker
• Servings: 6-8
• Cook Time: 6-8 hours on low (or 3-4 hours on high)
• Difficulty: Easy

Ingredient List

Here’s everything you’ll need to get started:

• 1 1/2 cups dried split peas (green or yellow, rinsed and sorted)
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 2 medium carrots, diced
• 2 celery stalks, diced
• 1 medium potato, peeled and diced (optional, for extra creaminess)
• 1 bay leaf
• 1 teaspoon dried thyme
• 1/2 teaspoon smoked paprika (optional, adds a subtle smoky depth)
• 6 cups vegetable broth (low-sodium recommended)
• Salt and black pepper, to taste
• Fresh parsley or chives, for garnish

Instruction Guide

Let’s walk through this step by step, slow-cooker style:

1. Prepare your vegetables: Dice onions, carrots, celery, and potato (if using). Mince the garlic. This prep is key-well-chopped vegetables cook evenly and release maximum flavor.
2. Rinse the split peas: Place them in a colander and rinse under cold water until the water runs clear. This helps remove excess starch and any impurities.
3. Layer ingredients in the slow cooker: Start with the split peas, then add chopped vegetables, garlic, bay leaf, thyme, paprika, and a pinch of salt and pepper. Pour in the vegetable broth on top.
4. Cook: Cover and set your slow cooker on low for 6-8 hours or on high for 3-4 hours. Resist the temptation to peek too often-slow cooking works best with patience.
5. Check consistency: The soup should be thick, with peas fully softened. If it’s too thick, stir in extra broth or water until you reach your preferred consistency.
6. Adjust seasonings: Taste the soup and add more salt, pepper, or spices if needed.
7. Blend (optional): For an ultra-smooth texture, use an immersion blender to puree part or all of the soup. Leave some chunks for a rustic feel.
8. Serve: Ladle into bowls and garnish with fresh parsley or chives. Add a swirl of olive oil if you like a richer mouthfeel.

Ingredient Swaps

Don’t worry if you don’t have exactly what’s listed. Here are some flexible alternatives:

• Split peas: Yellow or green peas both work; lentils are a faster-cooking alternative but may slightly change texture.
• Vegetable broth: Chicken broth or mushroom broth can be used if you’re not strictly vegetarian.
• Vegetables: Parsnips, sweet potatoes, or turnips can replace carrots or potato. Leeks are a great onion alternative.
• Herbs and spices: Swap thyme with rosemary or sage; paprika can be replaced with cumin for a warm, earthy flavor.

Helpful Tips

Here’s how to make your soup next-level:

• Rinse and sort peas carefully: Avoid grit in your soup.
• Layer flavors: Add more garlic or onions if you like depth.
• Stir occasionally: Even though slow cookers are low-maintenance, a quick stir midway helps prevent sticking.
• Thicken naturally: For a creamier soup, mash some of the peas against the side of the slow cooker before serving.
• Freeze in portions: This soup freezes beautifully for up to 3 months.

Customization Ideas

Make the soup uniquely yours with these tweaks:

• Spicy kick: Add a pinch of cayenne pepper or red pepper flakes.
• Herbal freshness: Top with fresh basil, cilantro, or dill instead of parsley.
• Savory umami boost: Add a splash of soy sauce or miso paste at the end.
• Crunchy garnish: Toasted pumpkin seeds or croutons add texture.
• Creamy swirl: Coconut milk or cashew cream adds indulgent creaminess without dairy.

FAQs

Can I Make Vegetarian Pea Soup In A Slow Cooker Without Soaking The Peas?

Yes, you can cook split peas in a slow cooker without soaking, but they may take longer to soften. Unsoaked peas usually require 6-8 hours on low heat or 3-4 hours on high heat. Soaking can reduce cooking time and improve digestibility.

What Vegetables Work Best In A Vegetarian Pea Soup Slow Cooker Recipe?

Carrots, celery, onions, and garlic are classic additions that enhance flavor. You can also add potatoes, leeks, bell peppers, or tomatoes depending on your taste preferences. Root vegetables give the soup a heartier texture.

Can I Use Fresh Peas Instead Of Dried Split Peas?

Fresh peas can be used, but they cook much faster than dried split peas and may become mushy if cooked for the full slow cooker duration. If using fresh peas, add them in the last 30-60 minutes of cooking.

Do I Need To Add Any Fat Or Oil To Make The Soup Taste Good?

While optional, adding a small amount of olive oil or butter can enhance the flavor and texture. Sautéing onions, garlic, and other aromatics in oil before adding them to the slow cooker can significantly deepen the flavor.

How Can I Make The Soup More Flavorful Without Meat Or Stock Cubes?

Use vegetable broth instead of water, and enhance the soup with herbs and spices like thyme, bay leaf, smoked paprika, or cumin. Adding umami-rich ingredients like mushrooms, nutritional yeast, or a splash of soy sauce can also increase depth of flavor.

How Thick Will The Soup Be, And Can I Adjust The Consistency?

Slow cooker pea soup tends to be thick due to the natural starch in split peas. To adjust consistency, add extra vegetable broth or water during or after cooking. For a smoother texture, use an immersion blender to puree part or all of the soup.

Can I Freeze Vegetarian Pea Soup For Later?

Yes, this soup freezes well. Allow it to cool completely, then transfer to airtight containers or freezer bags. It can be stored in the freezer for up to 3 months. Thaw in the refrigerator before reheating, and stir well as it may thicken upon freezing.

How Long Does It Take To Cook In A Slow Cooker?

Cooking times vary based on the slow cooker and whether peas were soaked. Typically, unsoaked peas take 6-8 hours on low or 3-4 hours on high. Soaked peas may require 4-6 hours on low or 2-3 hours on high.

Can I Add Grains Or Legumes For Extra Protein?

Yes, adding grains like barley, quinoa, or rice can make the soup more filling. Other legumes, such as lentils or chickpeas, can be added as well. Be mindful that cooking times may need adjustment to ensure all ingredients are tender.

How Do I Prevent The Soup From Burning In The Slow Cooker?

Stir occasionally and ensure there is enough liquid to cover the peas and vegetables. Using the low setting is safer for longer cooking times. Also, avoid thickening the soup too early, as split peas naturally thicken as they cook.
