There’s something quietly satisfying about a slow cooker transforming simple ingredients into something deeply flavorful. This split pea soup, made in the crockpot, is a prime example. It’s like a warm hug in a bowl, especially after a long day when you’re craving comfort without the fuss of constant stirring.
I love how the slow cooker lets the peas break down into a velvety, smoky broth, developing layers of flavor that feel like they’ve been simmering all day. In reality, it’s just a matter of tossing everything in and letting it do its thing. It’s honest cooking—no tricks, just patience and good ingredients.
This recipe is my go-to for chilly evenings or when I want something hearty and nourishing. It’s forgiving, adaptable, and it makes the kitchen smell like a cozy kitchen in winter. Honestly, I don’t think I’ve ever made it without a little sip of the broth while it’s bubbling away—pure comfort.
This recipe is inspired by the slow cooker’s ability to develop deep, smoky flavors over hours without much fuss, turning humble split peas into a rich, comforting soup that tastes like it’s been simmering all day, even when you’re short on time.
The inspiration behind this soup
- I first stumbled upon this recipe during a particularly hectic week when I needed something wholesome and effortless. The slow cooker became my quiet partner, transforming dried peas and humble aromatics into a bowl of rich, smoky goodness while I juggled life’s chaos. It’s funny how a simple dish can remind you that patience in the kitchen, like in life, always pays off.
- Every time I make this soup, I think back to those cold evenings when I’d come home exhausted, the kitchen filled with the scent of caramelized onions and toasted spices. It’s become a little ritual—set it and forget it, then ladle out a bowl that feels like a warm hug. Turns out, some of the best comfort food is born from the simplest moments of quiet persistence.

Ingredient breakdown: key components
- Yellow split peas: I love how these turn velvety and slightly sweet when cooked, but be sure to rinse them well to avoid grit—your soup will be smoother.
- Vegetable broth: Using homemade or store-bought broth adds a depth of smoky, umami flavor. If you want a richer taste, a splash of soy sauce works wonders.
- Smoked ham hock: It’s the secret to that deep, smoky richness, but if you’re vegetarian, smoked paprika can mimic that flavor—just don’t expect the same gelatinous texture.
- Onion and garlic: I start with a hefty onion and a couple of cloves of garlic—these form the aromatic base that makes the whole house smell inviting. Adjust to your taste; more garlic if you like a punch.
- Carrots and celery: These add sweetness and freshness, but if you’re out of celery, a pinch of fennel seeds can add a similar aromatic lift. Keep an eye on the sweetness—don’t overdo it.
- Bay leaf: Adds a subtle earthiness, but remember to remove it before serving; it can be overpowering if left in. A pinch of thyme can also brighten the dish.
- Salt and pepper: Essential, but go easy at first. The broth and ham hock are salty, so taste and adjust towards the end—your soup should taste balanced, not salty.

Notes for ingredient swaps
- Dairy-Free: Skip butter or cream—this soup is naturally creamy from the peas, but a splash of coconut milk can add richness without dairy.

- Low-Sodium: Use unsalted broth and reduce added salt—still hearty, just less salty and more control over seasoning.
- Gluten-Free: Ensure broth and any added ingredients are gluten-free; this soup is naturally GF but double-check labels if using pre-made broths.
- Extra Vegetables: Toss in chopped kale, spinach, or frozen peas near the end—adds color, texture, and a fresh pop of flavor.
- Herb Variations: Swap bay leaves for thyme or rosemary for a different aromatic twist—less earthy, more fragrant.

Equipment & Tools
- 6-quart slow cooker: Main cooking vessel for slow, even simmering.

- Cutting board: Providing a stable surface for prepping ingredients.
- Ladle: Serving the finished soup.
- Immersion blender (optional): Pureeing part of the soup for creaminess.
Step-by-step guide to split pea soup
- Gather your equipment: a 6-quart slow cooker, a sharp knife, a cutting board, and a ladle. The slow cooker will do the heavy lifting, while the knife and board prepare your ingredients.
- Rinse 1 pound of split peas under cold water until the water runs clear. This removes grit and prevents cloudiness in your soup. Set aside.
- Chop 1 large onion, 2 carrots, and 2 celery stalks into small dice. These form the aromatic base and add natural sweetness.
- If using a ham hock or smoked sausage, prepare them now. For ham hock, trim excess fat; for sausage, slice into rounds. These will deepen the smoky flavor.
- Place the rinsed peas, chopped vegetables, 4 cups vegetable broth, 2 cups water, and your smoked meat (if using) into the slow cooker. Add 2 bay leaves, a pinch of thyme, salt, and pepper to taste.
- Set the slow cooker on low and cook for 6-8 hours. During the first 4 hours, you might notice the peas start to break down and the broth thickens. The aroma will fill your kitchen with smoky, earthy notes.
- Check the soup around the 6-hour mark. If the peas are velvety and the vegetables are tender, it’s ready. If the texture is still too chunky, cook longer, up to 8 hours total.
- Remove the bay leaves and any smoked meat if used. Taste and adjust seasoning—more salt or pepper if needed. If you prefer a creamier texture, use an immersion blender directly in the pot to blend some of the soup, leaving it chunky if you like.
- Ladle the soup into bowls and let it rest for about 10 minutes off the heat. This allows flavors to settle and makes serving easier. Garnish with fresh herbs if desired.
- Serve hot with crusty bread or a simple salad. This soup tastes even better the next day as flavors meld—store in airtight containers for up to 3 days or freeze for up to 2 months.
Once cooked, remove bay leaves and smoked meat if used. Let the soup rest off the heat for 10 minutes to allow flavors to deepen. Ladle into bowls, garnish if desired, and serve hot.
How to Know It’s Done
- Peas are velvety and fully broken down, with a thick, smoky broth.
