Soups & Stews
This Andersen's split pea soup copycat recipe delivers the exact smoky, hearty flavor that made the original a diner classic. The secret lies in slow-cooked bacon and deeply caramelized onions that build layers of depth while simmering.
I've recreated it after years of testing, ensuring every spoonful delivers that perfect balance of creaminess and savory richness.
The professional technique starts with rendering thick-cut bacon until crisp, then removing all but the fat to create a flavorful base. Caramelizing onions for 30 minutes develops their natural sweetness, which forms the foundation of the soup's complex taste.
Split peas cook until tender but still hold their shape, absorbing all those rich flavors without turning mushy.
What you'll end up with is a velvety split pea soup with visible bacon bits throughout, caramelized onion chunks, and just enough cream to make it luxurious without being heavy.
The herbaceous notes from thyme and bay leaf tie everything together, creating a soup that's both comforting and sophisticated enough for any table.
This recipe serves 6-8 and takes about 2 hours of active and passive cooking time, but the results are worth every minute. The slow simmering process allows flavors to meld perfectly, while the final adjustment of salt and pepper ensures each bowl tastes exactly like the original.

Ingredients for andersen's split pea soup copycat
Thick-cut bacon, caramelized onions, and split peas create the hearty foundation for this diner-style soup copycat.
| Ingredient | Amount | Notes |
|---|---|---|
| Thick-Cut Bacon 🥓 | 12 oz | Thick-cut preferred for crispiness |
| Yellow Onions 🧅 | 3 large | Yellow or sweet onions work |
| Carrots 🥕 | 4 medium | Peeled and chopped into chunks |
| Dry Green Split Peas 🌱 | 2 cups | Unsoaked, not canned peas |
| Chicken Broth 💧 | 6 cups | Low-sodium preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped fine |
| Bay Leaves 🍃 | 2 whole | Remove before serving |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth |
| Salt 🧂 | 1 ½ tsp | Adjust to taste |

The bacon is non-negotiable—thick-cut renders best, giving you crispy bits and rich fat for the base. Costco or local butchers often carry the best quality in bulk. Caramelizing the onions for 30 minutes unlocks their natural sweetness, which is the secret to that diner-style depth. Yellow onions work best here, though sweet onions add a touch of brightness. For the split peas, Bob's Red Mill or any reputable brand works, but avoid canned—dry peas develop better texture. The broth should be low-sodium to control seasoning later.
No thick-cut bacon? Regular bacon cut into strips works, but it won't get as crispy. Substitute onions with leeks or shallots for a milder flavor. If you're short on time, pre-minced garlic is fine, but fresh minced adds more complexity. The heavy cream can be swapped for half-and-half if you prefer a lighter texture. For a vegetarian version, use vegetable broth and swap bacon for smoked paprika. The flour is just for thickening—if you're gluten-free, cornstarch works equally well.
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 for 3 months. The bacon bits crisp up beautifully when reheated—just add a splash of broth to loosen. For serving, I like to top each bowl with a dollop of sour cream or extra bacon bits. The caramelized onions keep well too, so make extra for sandwiches or salads.

Step-by-step instructions for Andersen's split pea soup
This method delivers restaurant-quality depth with smoky bacon and caramelized onions—just like Andersen's.
Cook and Crisp the Thick-Cut Bacon
Cut the 12 oz thick-cut bacon into ½-inch pieces and place them in a large Dutch oven over medium heat. Cook undisturbed for 5-6 minutes until the edges begin to crisp and the fat starts rendering. This initial crisping creates the smoky foundation for the soup.
Once the bacon is golden and the fat has rendered about halfway, stir occasionally for another 5 minutes until fully cooked. Remove the bacon with a slotted spoon and set aside on paper towels to drain, leaving the rendered fat in the pot. This bacon fat will serve as the cooking medium for the onions and carrots.
Caramelize Onions and Cook Carrots
In the same Dutch oven with the bacon fat, add the 3 large yellow onions cut into ½-inch wedges. Cook over medium heat for 10 minutes, stirring occasionally, until they begin to soften and turn translucent.
Add the 4 medium carrots cut into ½-inch chunks and continue cooking for another 10 minutes, stirring frequently. The onions should deepen to a rich golden brown while the carrots soften—this caramelization builds the soup's depth of flavor. If the mixture sticks, add 1-2 tablespoons of the 6 cups chicken broth to deglaze.
Toast the Split Peas and Add Aromatics
Stir in the 2 cups dry green split peas and cook for 2 minutes to lightly toast them, which enhances their nutty flavor. Add the 3 minced garlic cloves, 1 tbsp chopped fresh thyme, and 2 whole bay leaves, stirring for 30 seconds until fragrant.
Pour in the 6 cups chicken broth and bring to a simmer. Add the 1.5 tsp salt and 0.5 tsp black pepper, then return the cooked bacon to the pot. Partially cover and simmer for 45 minutes, stirring occasionally, until the peas begin to soften but aren't fully tender.
Thicken and Finish the Soup
In a small bowl, whisk together the 1 tbsp all-purpose flour and the 2 tbsp butter until smooth. Gradually stir this mixture into the simmering soup, allowing it to thicken for 2-3 minutes. The soup should coat the back of a spoon with a velvety consistency.
Remove the bay leaves and stir in the 0.5 cup heavy cream. Simmer for an additional 5 minutes to meld all flavors. Taste and adjust seasoning with additional salt or pepper if needed. The final soup should have a rich, smoky-sweet balance with tender peas and caramelized vegetables.
Pro Tips For Making Andersen'S Split Pea Soup Copycat
- CRISP THE BACON LOW: I learned this the hard way—cooking thick-cut bacon at medium heat gives you crispy edges without burning the middle. The fat renders slower, so you get that smoky depth Andersen’s version has without the acrid smoke alarm.
- SOAK PEAS 30 MINUTES: Skip the overnight soak, but give those dry split peas a 30-minute water bath first. It cuts cooking time by 20 minutes and prevents the soup from turning gummy later—trust me, your future self will notice.
- CHAR THE ONIONS: Don’t just slice and sauté—get those onions caramelized until they’re dark brown at the edges. It’s the thing that matters most for that deep, rich flavor. (Yes, even if you’re impatient like me.)
- ADD BROTH IN STAGES: Pour in half the chicken broth first, let it simmer until the peas are tender, then add the rest. This keeps the texture creamy instead of watery—no need for extra thickeners, and it saves you from ending up with a sad, thin soup.
Common mistakes when making your andersen's split pea soup copycat
Overcooking the Peas
Split peas should be tender but still hold their shape—overcooking turns them into mush, ruining the soup’s texture. I’ve seen home cooks simmer them for over 2 hours, which breaks down their structure.
Aim for 45-60 minutes of simmering after adding broth, checking at 45 minutes—they should be soft but not falling apart. 🌱
Skipping the Bacon Fat
The rendered bacon fat is the flavor foundation—don’t drain it completely! I’ve made this mistake by removing all the fat, leaving the soup tasting flat. Leave 2-3 tbsp of fat in the pot to sauté onions and carrots. This fat carries the smoky depth that defines Andersen’s version. 🥓
Rushing the Caramelization
Caramelizing onions for less than 30 minutes means missing out on their natural sweetness, which is key to the soup’s complexity. I once cut this step to 20 minutes and ended up with a bland base.
Use medium heat and stir occasionally—patience pays off with rich, golden onions that transform the soup. 🧅
Underseasoning the Broth
Using high-sodium broth or not adjusting salt properly can make the soup taste flat. I recommend starting with low-sodium broth and adding salt in layers—first when adding broth, then again at the end. Taste after simmering and adjust with ½ tsp increments until balanced. 🧂
Adding Cream Too Early
Stirring in the heavy cream before the soup is fully simmered can cause it to curdle or separate. Always add it in the final 5 minutes of cooking, after removing the bay leaves. This ensures a silky texture without breaking the emulsion. 🥛
Ignoring the Resting Time
Letting the soup sit for 10-15 minutes after cooking allows flavors to meld and thicken naturally. Skipping this step often leads to a thinner, less cohesive soup. I always cover the pot and let it rest before serving—it makes a noticeable difference in texture and taste. ⏳

Frequently asked questions
Why does Andersen's split pea soup taste so rich and smoky?
The secret lies in the slow-cooked thick-cut bacon and deeply caramelized onions. The bacon fat infuses the soup with smoky depth while the onions develop natural sweetness through 30 minutes of cooking. The combination creates that signature restaurant-style richness you can't get from shortcuts.
Can I make this soup in a slow cooker?
Yes! After cooking the bacon and caramelizing the onions/vegetables on the stovetop, transfer everything to your slow cooker. Add the split peas and broth, then cook on low for 4-5 hours (or high for 2-3 hours)). Finish by adding the flour-butter slurry and cream at the end as directed. The slow cooker works best for flavor development in this hearty soup.
What if my soup turns out too thick?
Add ½ cup of warm chicken broth or water at a time, stirring well after each addition. Heat gently until the desired consistency is reached. For a smoother texture, blend a portion of the soup and mix it back in. The key is gradual thinning—don't add too much liquid at once, or you'll dilute the flavors.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 5 days or freeze for 3 months. To reheat, warm on the stove over medium-low heat, stirring occasionally. Add a splash of broth if the soup seems too thick. The bacon bits will crisp up beautifully when reheated—just give them a quick toast in the pot.
What's the best way to serve this soup?
Garnish each bowl with extra crispy bacon bits, a dollop of sour cream, and fresh chopped thyme. Serve with crusty bread or oyster crackers for dipping. For a complete meal, pair it with a simple green salad. The contrast of textures and temperatures makes it even more satisfying.
