High Protein Classic Split Pea Soup is a hearty, comforting dish that’s both filling and full of flavor. Made with split peas, vegetables, and simple herbs, this soup is packed with plant-based protein and slow-cooked goodness. I love serving it on chilly days when I want something warm and satisfying that also fuels me.

Why You’ll Love This Recipe

I love this soup because it’s nutritious, affordable, and simple to make. The split peas break down into a naturally creamy texture as they simmer, creating a thick, rich base without needing cream. It’s high in protein and fiber, making it great for staying full longer. Whether I make it for a light lunch or a filling dinner, it always hits the spot.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Dried green split peas, rinsed
Olive oil
Yellow onion, chopped
Carrots, chopped
Celery, chopped
Garlic, minced
Bay leaf
Dried thyme
Salt and black pepper
Vegetable broth or chicken broth
Optional: chopped parsley for garnish

Directions

I start by heating olive oil in a large soup pot over medium heat and sauté the onion, carrots, and celery until softened.
I stir in the garlic, thyme, salt, and pepper, and cook for another minute until fragrant.
I add the split peas, broth, and bay leaf, then bring the mixture to a boil.
I reduce the heat to low and simmer, partially covered, for 60 to 75 minutes, stirring occasionally, until the peas have broken down and the soup thickens.
I remove the bay leaf, adjust the seasoning to taste, and serve hot, garnished with fresh parsley if I like.

Variations

I sometimes use yellow split peas instead of green for a slightly sweeter flavor. For a smoother texture, I blend half the soup and mix it back in. To boost the protein even more, I stir in a scoop of unflavored protein powder just before serving—it dissolves easily and doesn’t affect the taste. I also like adding chopped spinach or kale at the end for extra nutrition.

storage/reheating

I store leftovers in the fridge for up to 5 days. The soup thickens as it sits, so I add a splash of water or broth when reheating. I reheat it gently on the stove or in the microwave. It also freezes really well—I let it cool completely, portion it into containers, and freeze for up to 3 months.

FAQs

Are split peas high in protein?

Yes, split peas are an excellent source of plant-based protein and fiber. I love using them to make filling meals that keep me satisfied.

Do I need to soak the split peas?

No soaking is needed. I rinse them well before cooking, and they soften as they simmer.

Can I make this in a slow cooker?

Yes, I add all the ingredients to the slow cooker and cook on low for 8 hours or on high for about 4–5 hours, until the peas are tender.

Is this soup gluten-free?

It is naturally gluten-free, as long as I make sure the broth I’m using is free from hidden gluten-containing ingredients.

Can I blend the soup?

Yes, I blend part or all of the soup if I want a smoother texture. I usually use an immersion blender right in the pot for easy cleanup.

Conclusion

High Protein Classic Split Pea Soup is a cozy, nourishing meal that I can rely on for both taste and nutrition. With just a few simple ingredients, this soup becomes thick, flavorful, and full of plant-based protein. Whether I enjoy it as a quick lunch or prep it ahead for the week, it’s one of those recipes I keep in regular rotation.
