There’s something uniquely grounding about a bowl of homemade soup. It’s the kind of food that wraps around you like a warm blanket, a dish that often carries the weight of cherished memories.

It’s a hearty split pea soup recipe, simple yet profound, and perfect for those chilly evenings when you just need a little extra comfort.
The Nostalgia of Homemade Soup
Few dishes evoke a sense of home quite like a steaming bowl of soup. It’s a classic, often tied to family traditions and stories shared around the kitchen table. Our Grandpa’s split pea soup embodies this perfectly. It’s a straightforward, unpretentious meal, but one that’s rich in flavor and feeling. Every spoonful is a reminder of simpler times, of warmth, and of the care put into a truly comforting homemade soup. This isn’t just a meal; it’s a hug in a bowl, a tradition that continues to nourish both body and soul.
Essential Ingredients for Grandpa’s Split Pea Soup
Making a truly memorable soup starts with good ingredients. For this classic split pea soup, we focus on fresh, simple components that build deep, satisfying flavors without fuss.
The Legumes: Dried Green Split Peas and Frozen Green Peas
The foundation of this soup, of course, is the peas. We use both dried green split peas and frozen green peas. The dried split peas are the star, providing that earthy, robust flavor and creamy texture as they break down during cooking. They give the soup its signature body and deep, savory base. Later, we introduce frozen green peas. These add a wonderful contrast, a sweet pop of vibrant color and fresh taste that brightens the whole dish. The combination gives you a lovely split pea and green pea soup with varied textures and flavors.
The Aromatic Base: Yellow Onion, Carrots, and Celery
Every great soup begins with a strong foundation, and for this recipe, that means a classic mirepoix. Diced yellow onion, carrots, and celery are gently sautéed to soften and release their natural sugars. This trio forms the aromatic backbone, lending a subtle sweetness and a savory depth that permeates the entire soup. It’s the secret to building layers of flavor right from the start, ensuring a robust and welcoming aroma.
Flavor Builders: Garlic, Dried Bay Leaf, Kosher Salt, and Black Pepper
With our base established, we add the essential flavor builders. Fresh garlic, minced finely, brings its pungent warmth to the mix. A dried bay leaf contributes a subtle, almost woodsy note that rounds out the savory profile. Kosher salt and freshly ground black pepper are crucial for seasoning at every stage, allowing us to build and balance the flavors as the soup simmers. These simple seasonings are key to creating a truly delicious and deeply flavored soup.
The Liquids: Vegetable Broth and Water
For a rich and flavorful broth, we rely on a combination of vegetable broth and water. Using vegetable broth ensures this is a delicious vegetarian split pea soup. The broth provides a savory base, while a bit of water helps to achieve the ideal simmering consistency and prevents the soup from becoming overly concentrated as the peas break down. This ratio ensures a perfect balance of flavor and thickness as the soup cooks.
The Finishing Touches: Extra Virgin Olive Oil, Fresh Parsley, and Lemon Juice
The final touches make all the difference. A drizzle of good quality extra virgin olive oil at the end adds a touch of richness and silky mouthfeel. Fresh parsley, chopped finely, provides a burst of herbaceous freshness and a lovely green garnish. And a squeeze of fresh lemon juice is the ultimate secret ingredient. It brightens all the flavors, cutting through the richness and adding a delightful zing that elevates the entire dish, making it taste incredibly vibrant and well-balanced.
Step-by-Step Cooking Instructions
Making this comforting homemade soup is straightforward. Follow these steps for a delicious meal.
Sautéing the Mirepoix
Start with a large, heavy-bottomed pot or Dutch oven. Add a tablespoon or two of extra virgin olive oil and heat it over medium heat. Once shimmering, add your diced yellow onion, carrots, and celery. Cook these aromatics gently, stirring occasionally, until they soften and the onion becomes translucent, usually about 8-10 minutes. Don’t rush this step; it’s where much of the soup’s fundamental flavor is developed. Stir in the minced garlic for the last minute of cooking until fragrant, being careful not to let it burn.
Simmering the Broth
Once the vegetables are soft and fragrant, it’s time to add the dried green split peas, ensuring they are rinsed thoroughly under cold water first. Pour in the vegetable broth and water, then add the dried bay leaf, kosher salt, and black pepper. Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer gently. The peas will need to cook until they are very tender and have started to break down, which typically takes about 45-60 minutes. Stir occasionally to prevent sticking.

Partially Pureeing for the Perfect Texture
This is where we achieve that lovely, thick, and chunky consistency unique to this soup. Once the dried split peas are thoroughly cooked and soft, remove the bay leaf from the pot. Using an immersion blender, carefully blend about half to two-thirds of the soup directly in the pot. You want to create a smooth, creamy base while still leaving plenty of whole or partially mashed peas and vegetables for texture. This “partially pureed pea soup” technique gives it a satisfying mouthfeel without being entirely smooth. If you don’t have an immersion blender, carefully transfer about half of the soup to a regular blender, puree until smooth, and then return it to the pot.

Stirring in the Final Additions
With the desired texture achieved, it’s time for the finishing touches. Turn off the heat. Stir in the frozen green peas; the residual heat from the soup will be enough to warm them through without overcooking them and losing their bright color and sweet pop. Finally, stir in the fresh parsley and the squeeze of lemon juice. Taste the soup and adjust the seasoning with more salt or pepper if needed. The lemon juice is key here – don’t skip it, as it truly brightens all the flavors and adds a fantastic lift.
Proper Storage and Reheating Tips
This hearty split pea soup recipe makes fantastic leftovers, often tasting even better the next day as the flavors deepen. Allow the soup to cool completely before transferring it to airtight containers. It will keep well in the refrigerator for up to 3-4 days. For longer storage, it freezes beautifully for up to 3 months. To reheat, gently warm the soup on the stovetop over medium-low heat, stirring occasionally, until it’s hot throughout. If the soup has thickened too much in the fridge, you can add a splash of vegetable broth or water to reach your desired consistency. Avoid reheating at a rolling boil to prevent the peas from becoming mushy. Serve with an extra sprinkle of fresh parsley if desired.
We hope you enjoy making this comforting homemade soup as much as we do. It’s a truly special dish that brings warmth and flavor to any table. If you try our take on how to make split pea soup, we’d love to hear from you!

- 1 whole Dried bay leaf
- 1 tbsp Lemon juice Freshly squeezed
Instructions
- Heat the olive oil in a large heavy-bottomed Dutch oven or soup pot over medium heat.
- Add the diced yellow onion, carrots, and celery. Sauté for 8 to 10 minutes until the vegetables are softened and the onion is translucent.

- When the dried split peas are completely tender and begin to break down, remove the pot from the heat. Discard the dried bay leaf.
- Use an immersion blender to partially puree the soup right in the pot, leaving some chunks for a hearty, rustic texture. Alternatively, transfer two cups of the soup to a standing blender, puree until smooth, and stir it back into the pot.
- Stir in the thawed frozen green peas, fresh parsley, and lemon juice. Let the soup rest for 5 minutes off the heat to allow the flavors to meld and the frozen peas to warm through.
