Ingredients for 5 star split pea and ham soup

Transform humble pantry staples into a restaurant-worthy bowl of smoky-sweet comfort.

The ham hock is non-negotiable for that deep, smoky flavor—look for bone-in cuts at stores like Whole Foods or your local butcher. Celery crowns (the leafy tops) are often discarded, but they add that signature crunch. Save them in a damp paper towel in the fridge until ready to crisp. For the split peas, pick over them carefully—even a small stone can ruin the texture. If you can't find smoked ham hock, substitute with regular ham bone, but you'll miss that smoky aroma. The carrots and onion can be prepped ahead, but keep the garlic and herbs fresh until you're ready to cook—they release their oils best when added fresh.

No smoked ham hock? Regular ham bone with a splash of liquid smoke works in a pinch, though it won't be identical. Fresh thyme is ideal, but dried works at one-third the amount. If you're short on time, pre-cut frozen celery crowns from Trader Joe's save prep work. The balsamic vinegar isn't just for flavor—it helps balance the richness of the ham. For a deeper color, add a pinch of turmeric to the peas while simmering. And if you're making this ahead, freeze the broth separately—it keeps for months and makes quick soup assembly a breeze.

This soup tastes even better the next day as flavors meld. Store in an airtight container in the fridge for up to 5 days, or freeze the broth and peas separately for 3 months. The crisp celery crowns should be added fresh right before serving—toss them in olive oil and toast in a dry pan for 2 minutes to keep them crisp. For a restaurant-style finish, garnish with a drizzle of balsamic glaze and extra parsley. Leftovers reheat beautifully—just add a splash of water or broth to loosen the soup.

Step-by-step instructions for smoky-sweet split pea and ham soup

Transform simple ingredients into a restaurant-worthy soup with rich, smoky depth and crispy celery garnish.

Heat the 2 tablespoons olive oil in a large Dutch oven over medium-high heat. Add the 1 lb smoked ham hock and sear on all sides until deeply browned, about 8-10 minutes. This step develops intense flavor through the Maillard reaction—don't rush it, even if it takes longer.

Once browned, remove the ham hock and set it aside. You'll notice the oil will be dark and fragrant—this is where the soup's depth begins. Leave the browned bits in the pot, as they'll form the flavor base for your soup. Real talk: skipping this step means missing out on that smoky, caramelized complexity.

In the same Dutch oven, add the 1 large yellow onion (halved), 3 medium carrots (cut into chunks), and 3 whole celery stalks (cut into 1-inch pieces). Cook for 6-8 minutes until the vegetables soften slightly and the onion becomes translucent.

Add the 4 cloves garlic cloves (minced) and 0.25 cup fresh thyme (or 1 tablespoon dried) and cook for another 1-2 minutes until fragrant. Here's the thing—cooking the garlic just until fragrant prevents it from becoming bitter. If it starts to brown too quickly, reduce the heat slightly.

Return the ham hock to the pot. Add 1.5 cups dried split peas, 2 whole bay leaves, 1 teaspoon black peppercorns, and 2 teaspoons salt. Pour in 8 cups water (enough to cover all ingredients by about 2 inches) and bring to a boil over high heat.

Once boiling, reduce heat to low and cover partially. Let it simmer for 1.5 hours, stirring occasionally. The split peas should soften and the soup should thicken naturally. I check for doneness by tasting a pea—it should be tender but still hold its shape. If the soup looks too thick, add ½ cup water to reach your preferred consistency.

After simmering, remove the ham hock and discard the bone. Shred the meat into small pieces and return it to the pot. Stir in 1 tablespoon balsamic vinegar and simmer for another 5 minutes to let the flavors meld. The balsamic adds a subtle sweetness that balances the smokiness perfectly.

For the crisp celery crowns, cut the remaining celery leaves into small pieces and toss with 1 teaspoon olive oil, ½ teaspoon salt, and ¼ teaspoon black pepper. Spread on a baking sheet and bake at 400°F for 8-10 minutes until crispy. Garnish each serving with these crispy celery pieces and 0.1 cup chopped fresh parsley just before serving.

Balsamic Glaze Finish

The 1 tablespoon balsamic vinegar I use at the end isn’t just for flavor—it’s the secret weapon that ties everything together. Heat the vinegar in a small saucepan until it reduces by half (about 3-4 minutes on medium heat), then drizzle it over the finished soup.

This creates a glossy, slightly sweet glaze that cuts through the richness of the ham while adding depth. For extra shine, add ½ teaspoon honey to the reduction. 🍷

Crispy Celery Crowns

These aren’t just garnishes—they’re the textural star of the dish! Toss the celery leaves with 1 teaspoon olive oil, ½ teaspoon salt, and ¼ teaspoon black pepper, then bake at 400°F for 8-10 minutes until golden and crisp.

The key is to spread them in a single layer so they don’t steam. For a shortcut, use pre-cut frozen celery crowns from Trader Joe’s—just toss them with oil and bake as directed. 🧅

Fresh Herb Garnish

The 0.1 cup chopped fresh parsley at the end adds brightness and color, but don’t stop there. A sprinkle of fresh thyme leaves or even chopped chives elevates the dish further.

For a pop of acidity, add a pinch of lemon zest right before serving. The herbs should be added after the celery crowns so they stay vibrant and fresh-tasting. 🌿

Smoked Paprika Swirl

For a smoky depth that mimics the ham hock, whisk ½ teaspoon smoked paprika into 1 tablespoon warm water until smooth. Drizzle this mixture over each bowl just before serving.

It’s a subtle but powerful way to enhance the smoky notes without overpowering the dish. I keep this trick handy for any ham-based soup—it’s a game-changer. 🌶️

Creamy Dill Twist

Stir 2 tablespoons sour cream or Greek yogurt into individual bowls before adding the celery crowns for a creamy contrast. A sprinkle of fresh dill (about 1 teaspoon chopped) adds a bright, herby note that balances the richness.

This works especially well if you’re serving the soup with crusty bread—it soaks up the creamy drizzle beautifully. 🥄

Spicy Kick Option

For heat lovers, add ½ teaspoon cayenne pepper or 1 teaspoon hot sauce (like Cholula) to the soup while simmering. If you prefer a smoky heat, mix ¼ teaspoon chipotle powder with 1 teaspoon water and stir it in during the final 5 minutes of cooking.

The balsamic glaze will mellow the heat slightly, creating a perfect balance. 🔥
