Soups & Stews
This ATK split pea soup recipe delivers the ultimate comfort in a bowl—crispy celery crowns floating atop a rich, smoky ham-infused velouté that's been simmered to perfection.
The secret lies in slow-cooking dried peas until they're tender yet still hold their shape, while crisping the celery tops in the final minutes for that signature crunch.
This isn't just soup; it's a labor of love that transforms humble ingredients into a restaurant-worthy meal with deep historical roots as America's classic budget-friendly dish.
The foundation begins with properly soaked split peas and a flavorful broth built from onions, carrots, and potatoes that break down into silky texture. Adding smoked ham hocks (or smoked ham for convenience) infuses the soup with that unmistakable smoky depth that makes this version stand apart from basic recipes.
The key technique is simmering just until the peas are tender but still maintain their structure—overcooking turns them mushy, and we're aiming for that perfect al dente texture.
What sets this apart is the crispy celery crowns—those golden, caramelized tops that add a textural contrast to every spoonful. The soup itself develops a velvety consistency from the potatoes and ham, creating a rich velouté that coats your spoon.
Each bite delivers the harmony of earthy peas, smoky ham, and that satisfying crunch from the celery—it's the kind of meal that makes you want to linger at the table, savoring every last drop.
Perfect for chilly evenings or holiday gatherings, this soup scales beautifully and tastes even better the next day as flavors meld. The crispy celery crowns are the showstopper, but the real magic happens in the slow simmer that transforms simple ingredients into something extraordinary.

The split peas are the heart of this soup—rinsed well to remove debris before cooking. Dried peas (not canned) develop that signature creamy texture when simmered low and slow. For the ham, smoked vegetarian ham from Trader Joe's or Whole Foods gives that unmistakable depth without meat. The potatoes and carrots should be evenly sized—about 1.5-inch cubes—to cook uniformly. Celery crowns? Save the leafy tops for crisping, reserving the stalks for the broth. Fresh thyme and bay leaves add aromatic layers that elevate this beyond basic recipes.
No smoked ham? Smoked paprika plus liquid smoke (¼ tsp each) mimics the flavor—Trader Joe's has both in their spice aisle. Short on celery crowns? Extra celery stalks chopped into ½-inch pieces work for the broth, but you’ll miss that signature crunch. The bouillon cubes are non-negotiable for that umami punch—Knox brand is vegetarian-friendly and dissolves perfectly. For extra richness, add ½ cup coconut milk at the end (trust me on this). The vinegar might seem odd, but it brightens the peas and balances the smokiness—don’t skip it!
This soup tastes even better the next day as flavors meld. Store in airtight containers for 4-5 days in the fridge or 3 months frozen. For crispy celery crowns, fry them fresh in olive oil just before serving—they lose crunch if made ahead. Double the batch and freeze half; perfect for lazy weeknights. The peas thicken as they cool, so add a splash of broth when reheating. Leftovers? Blend a portion for creamy split pea dip—game changer!

Step-by-step instructions for crispy celery crowns over smoky ham velout
This soup delivers a luxurious texture contrast—silky velouté topped with crispy celery crowns and smoky ham.
Sauté the Vegetable Base
Heat the 0.25 cup olive oil in a large Dutch oven over medium heat. Add the diced yellow onion, chopped carrots, and chopped celery stems, cooking for 8-10 minutes until softened and fragrant. The vegetables should release their moisture and begin to caramelize slightly.
Stir in the minced garlic cloves and cook for 30 seconds until aromatic. Here's the thing—don't let the garlic burn. It should smell sweet and earthy, not bitter. Add the 2 whole bay leaves and 1 tbsp chopped fresh thyme next, stirring to combine. These herbs will infuse the broth with deep, savory notes as it simmers.
Build the Velouté with Peas and Potatoes
Add the 1.5 cups dried green split peas (rinsed) and the cubed russet potatoes to the pot. Pour in 8 cups water (enough to cover everything by about 2 inches) and crumble in the 2 smoked vegetable bouillon cubes. Bring to a boil, then reduce heat to low and simmer for 45 minutes, stirring occasionally.
After 45 minutes, the split peas should begin to soften, and the potatoes should be tender when pierced with a fork. This is when you'll add the diced smoked vegetable ham and 1.5 tsp salt. The ham will release its smoky flavor into the broth, while the salt enhances all the natural sweetness of the vegetables. Stir well and continue simmering for another 30 minutes until the peas are fully tender.
Finish with Vinegar and Crisp the Celery Crowns
Remove the pot from heat and stir in the 1 tbsp apple cider vinegar. This brightens the flavors and cuts through the richness of the ham. Taste and adjust seasoning with black pepper if needed. The soup should be rich but balanced, with a touch of tang.
While the soup finishes, heat a separate skillet over medium-high heat with 1 tablespoon olive oil. Add the 6 whole celery crowns (tops only) and cook for 4-5 minutes on each side until deeply golden and crispy. This is the moment that matters—don't walk away. The celery should develop a caramelized crust while staying tender inside.
Assemble and Serve
Ladle the velouté into bowls, placing 2-3 crispy celery crowns on top of each serving. The contrast of the silky soup and crispy celery is what makes this dish special. Garnish with additional chopped fresh thyme if desired.
Serve immediately while the celery crowns are still crisp. The soup will keep warm for about 20 minutes, but the celery loses its crunch quickly. Pair with crusty bread to soak up every last bit of that smoky, herby velouté.
Pro Tips For Making Atk Split Pea Soup
- SOAK THE PEAS FIRST: I learned this the hard way—skipping the soak makes your split peas turn into mush instead of tender, creamy perfection. Just cover them in water for at least 2 hours (or overnight if you’re patient) before cooking. The longer they soak, the faster they cook and the better they hold their shape.
- CHOP POTATOES SMALLER THAN YOU THINK: I used to cut them into big chunks like I was making mashed potatoes, and they’d turn to glue by the end. For this soup, dice them no bigger than ½-inch—small enough to disappear but big enough to stay intact. The secret’s in the even cooking.
- DON’T SKIP THE BOUILLON CRUSH: That smoked vegetable bouillon cube isn’t just flavor—it’s the soul of this soup. Instead of dropping it whole into the pot, mash it into the broth first. The crushed bits dissolve faster and spread that smoky depth evenly, so every spoonful tastes like it’s been simmering for hours.
- ADD CARROTS LAST: I was skeptical until I tried it: tossing in the carrots with the potatoes means they’ll turn to mush while the potatoes stay firm. Instead, wait until the potatoes are nearly done (about 15 minutes into simmering) before adding the carrots. They’ll cook just enough to soften without disappearing.
Serving suggestions for this recipe
Crusty Bread Pairings
This soup practically begs for a sturdy bread to soak up every last drop of that smoky velouté. I reach for sourdough or a rustic baguette from my local bakery—Breads Bakery makes an excellent choice.
The dense crumb absorbs the soup beautifully while adding a satisfying chew. For extra flair, brush the bread with garlic-infused olive oil and sprinkle with flaky sea salt before serving. 🥖
Cheese Toppings
Add a final touch of richness with sharp cheddar or Gruyère shavings. I like to use a microplane to create delicate curls that melt slightly when the hot soup touches them.
For a vegetarian twist, try smoked Gouda—it complements the ham's smokiness perfectly. Just ½ cup per bowl is plenty; you don't want to overpower the delicate flavors. 🧀
Herb Garnishes
Fresh herbs elevate this soup from hearty to extraordinary. I always finish with chopped parsley and a sprinkle of fresh dill for brightness. If you have chives, their mild onion flavor pairs beautifully too.
For a pop of color, add edible flowers like nasturtiums—they're surprisingly tasty and add visual appeal. 🌿
Side Dish Ideas
For a complete meal, serve with roasted Brussels sprouts tossed in balsamic glaze or crispy roasted potatoes with paprika and rosemary. Both sides cut through the soup's richness while adding texture.
If you're serving a crowd, garlic breadsticks are a crowd-pleaser that pairs perfectly with the crispy celery crowns. 🥔
Beverage Pairings
This soup's smoky depth pairs wonderfully with dark ales like Guinness or Samuel Smith's Nut Brown Ale. For wine lovers, a Pinot Noir with its earthy notes complements the split peas beautifully. If you prefer something lighter, sparkling apple cider adds a refreshing contrast to the richness. 🍷
Make-Ahead Tips
Make the soup one day ahead—flavors deepen overnight. Store in an airtight container and reheat gently on the stovetop. Do not reheat the crispy celery crowns; fry them fresh before serving.
For extra richness, stir in ½ cup coconut milk when reheating. The soup thickens as it cools, so add a splash of broth if it seems too thick. ⏰

Frequently asked questions
Why do I need to crisp the celery crowns separately?
The crispy celery crowns add the perfect textural contrast to this rich, velvety soup. When cooked in the soup, they'd turn mushy. Crisping them separately in olive oil preserves that satisfying crunch while adding a caramelized flavor that elevates each bite. Think of them as the soup's edible garnish that makes it restaurant-worthy!
Can I make this soup vegetarian?
Simply replace the smoked ham with smoked paprika (¼ tsp) + liquid smoke (¼ tsp) for that signature depth. For extra umami, add ½ cup mushrooms with the vegetables. The bouillon cubes are already vegetarian-friendly, so you'll maintain all the rich, smoky flavors without meat.
How do I prevent the split peas from turning mushy?
Simmer the peas gently at low heat and check their texture at 45 minutes—they should be tender but still hold their shape. Overcooking is the #1 culprit! If they're not quite done after 75 minutes total, add ½ cup water and simmer another 15 minutes**. Never boil vigorously, which breaks down the peas too quickly.
Can I use canned split peas instead of dried?
While canned peas will work in a pinch, dried peas develop that signature creamy texture that canned can't match. For best results, stick with dried—simmering them transforms their starches into velvety richness. If you're short on time, add ½ cup coconut milk at the end to mimic that texture difference.
What's the best way to store leftovers?
Store the soup in an airtight container in the fridge for 4-5 days or freeze for 3 months. Save the crispy celery crowns for fresh frying when reheating—never store them with the soup. When reheating, stir in a splash of broth if the soup thickens too much. The flavors actually improve overnight!
