The split peas are the foundation here. Goya or Bob’s Red Mill are reliable brands—just check for bright green color and no signs of moisture. I grab mine from Whole Foods bulk bins when I can. The bay leaves should be whole and fragrant; McCormick or Badia are solid grocery store picks. For the broth, Swanson or Pacific Foods have good low-sodium options that let you control the salt.

No ham hock? Smoked paprika at 1 tsp adds a similar depth (vegetarian-friendly). Out of thyme? Marjoram at half the amount works in a pinch. Fresh carrots and celery are ideal, but frozen mirepoix mix saves time without sacrificing much flavor. If your split peas are old, they might need extra liquid—just add 1 cup hot water if the soup gets too thick.

This soup tastes even better the next day. Keeps 4-5 days in the fridge, freezes for 3 months. Store leftovers in airtight containers, and freeze in portions for easy reheating. The peas will thicken it more over time, so thin with broth or water as needed.

Step-by-Step Instructions for Split Pea Soup in the Crock Pot

Everything you need for a hearty, hands-off soup that practically cooks itself.

Step 1: Sauté Vegetables for Depth of Flavor

Heat the 1 tbsp Olive Oil in a large skillet over medium heat. Add the 1 whole Yellow Onion, 2 whole Carrots, and 2 whole Celery Stalks, all diced, and cook for 5-7 minutes until softened and just beginning to brown.

Stir in the 3 cloves Garlic Cloves and cook for 30 seconds until fragrant. This step builds the flavor foundation for your soup, so don’t rush it. The vegetables should be tender but not mushy.

Transfer the mixture to your crock pot. If using, add the 1 whole Ham Hock now—it will infuse the soup with smoky richness as it cooks.

Step 2: Combine Remaining Ingredients

Add the 1 lb Dried Green Split Peas to the crock pot, followed by the 6 cups Vegetable Broth. Stir in the 1 tsp Dried Thyme, 1 tsp Salt, and 1 tsp Black Pepper.

Tuck the 2 whole Bay Leaves into the mixture. These will steep like tea bags, adding subtle aroma. Make sure the peas are fully submerged in the broth—this prevents dry spots that could lead to uneven cooking.

Give everything a good stir to combine. The peas will expand as they cook, so there’s no need to worry about overfilling your crock pot at this stage.

Step 3: Slow Cook to Perfection

Cover the crock pot and cook on low heat for 6-7 hours or on high heat for 3-4 hours. You’ll know it’s ready when the peas have broken down into a thick, creamy texture and the Ham Hock (if using) falls apart easily.

About halfway through cooking, give the soup a stir to prevent the peas from sticking to the bottom. If the soup seems too thick, add a splash of warm water or additional broth, but keep in mind it will thicken as it cools.

Remove the Bay Leaves and discard. If using the Ham Hock, remove it, shred the meat, and return the meat to the soup for added texture and flavor.

Step 4: Adjust and Serve

Taste the soup and adjust the seasoning if needed. The 1 tsp Salt might need a boost, depending on the saltiness of your broth. If the soup is too thick, thin it with a little warm water or broth.

Ladle the soup into bowls and serve hot. The texture should be thick and hearty, with visible flecks of vegetables and a rich, earthy flavor from the peas and aromatics.

For the best results, let the soup sit for 10 minutes after cooking to allow the flavors to meld together. This dish tastes even better the next day, so don’t hesitate to make a big batch for leftovers.

Flavor Customization for This Recipe

Herb Variations

Swap the 1 tsp Dried Thyme for rosemary to add a piney depth that pairs beautifully with the earthy peas. For a Mediterranean twist, use ½ tsp oregano and ½ tsp marjoram instead. These herbs brighten the flavor without overpowering the dish.

Spice It Up

Add ½ tsp smoked paprika for a subtle, smoky warmth that mimics the depth of a ham hock. For heat, stir in ¼ tsp cayenne pepper or a dash of hot sauce at the end. I love a pinch of cumin for an unexpected earthy note. 🌶️

Creamy Additions

For extra richness, stir in ½ cup coconut milk or ¼ cup heavy cream during the last 30 minutes of cooking. This creates a silky texture that balances the heartiness. A dollop of Greek yogurt on top adds a tangy finish.

Vegetable Boosters

Add 1 diced potato or ½ cup diced sweet potato for extra body and natural sweetness. For greens, stir in 2 cups chopped spinach or kale in the last 15 minutes. These additions keep the soup hearty and nutritious.

Acidic Balance

Brighten the flavors with 1 tbsp lemon juice or apple cider vinegar just before serving. This cuts through the richness and lifts all the other flavors. A splash of white wine added at the beginning also adds complexity. 💡

Texture Twists

For a chunkier soup, mash only half the peas with a potato masher. For a smoother texture, use an immersion blender for 30 seconds before serving. I prefer leaving some peas whole for a rustic, hearty feel.
