Instant Pot Split Pea & Lentil Soup

Introduction

A cozy, nourishing start.
As a recipe developer I gravitate toward dishes that balance comfort and efficiency, and this Instant Pot split pea and lentil soup delivers both in spades. The combination of split peas and lentils creates a reassuringly thick, spoonable texture while staying lighter than cream-based alternatives. The Instant Pot shortens the hands-on time and concentrates savory depth, making it an ideal choice for chilly evenings or busy meal-prep days.
This soup is the kind of bowl that invites slow eating and conversation. It carries rustic character from the softened mirepoix and gentle aromatics, while the smoked paprika and bay leaves add subtle background notes that linger. I love dishes that transform simple pantry staples into something soulful, and this one does exactly that—requiring modest effort but offering generous returns.
When I write recipes like this I think about layering: the order of sautéing, the decision to partially purée for creaminess, and the final brightening touch before serving. These layers are what make a humble pot of legumes feel thoughtfully composed. Keep reading for a complete ingredient list and step-by-step method designed for reliable weeknight success.

Why You’ll Love This Recipe

Practical, flavorful, and satisfying.
There are several reasons this Instant Pot soup earns a spot in my regular rotation. First, texture: the blend of split peas and lentils creates depth without needing heavy thickeners. Second, convenience: using a pressure cooker concentrates flavor quickly, so you get that slow-simmered satisfaction in a fraction of the time. Third, versatility: the soup adapts to dietary needs and pantry supplies, making it perfect for weeknight dinners, batch cooking, or a simple lunch with crusty bread.
I also love that this recipe is forgiving. The aromatics provide a flavor backbone that supports optional additions—smoky cured meat for extra umami or extra lemon for brightness. For people who care about protein and fiber, this bowl is a winner. For those who value cleanup and speed, the Instant Pot helps deliver both. As a food writer, I look for recipes that taste more impressive than they are difficult to make—this one hits that sweet spot, delivering restorative warmth without a lot of fuss.
Finally, it’s an economical recipe: pantry legumes and basic vegetables make it a budget-friendly choice that doesn’t compromise on flavor. That combination of thrift, heartiness, and comfort is why this soup often appears in my seasonal menus.

Flavor & Texture Profile

What to expect in every spoonful.
This soup sits in the comforting spectrum between rustic and refined. Expect a base of gently sweet onions and carrots that anchor each bite, while celery adds that essential savory aromatic backbone. The legumes bring an earthy, nutty element that becomes silky when partially puréed—this technique creates a velvety body while preserving some whole legumes for bite. The smoked paprika contributes a soft, smoky warmth that plays nicely with the long-simmering savor of bay leaves and thyme.
On the palate the soup is multilayered: there’s initial creaminess followed by subtle grainy texture from the legumes, then fresh herbal brightness on the finish. If you choose the optional cured meat, it introduces a salty, smoky counterpoint that elevates the overall complexity. A squeeze of lemon at the end adds a lift—a high note that brightens the dense legume flavors without undermining their richness.
When garnished with fresh parsley, the dish gains freshness and a vegetal pop. Texture-wise, you’ll notice how partial puréeing gives body and mouth-coating presence, while whole legumes keep the eating experience pleasantly varied. This interplay is what turns a simple soup into a bowl you’ll want to savor slowly.

Gathering Ingredients

Everything you need on the counter before you start.

• 1 cup split green peas (dried)
• 1/2 cup brown or green lentils
• 1 tbsp olive oil
• 1 medium onion, diced
• 2 carrots, peeled and diced
• 2 celery stalks, diced
• 3 cloves garlic, minced
• 1 tsp smoked paprika
• 1 tsp dried thyme
• 2 bay leaves
• 6 cups vegetable broth (or low-sodium chicken broth)
• 1 tsp salt
• 1/2 tsp freshly ground black pepper
• 1 tbsp lemon juice (optional)
• 2 tbsp chopped fresh parsley for garnish
• Optional: 4 oz diced ham or cooked bacon for non-vegetarian version

As a cook, I always recommend staging ingredients in small bowls if you're multitasking. Having aromatics chopped and spices measured before you heat the oil reduces the temptation to overcook or burn anything. If using bacon or ham, have it diced and ready so it can be added at the appropriate step without delay. For the freshest aromatic lift, chop parsley just before serving.
In a practical sense, this list is deliberately pantry-friendly: dried legumes, common aromatics, and just a few seasonings produce a layered bowl without a long shopping list. If you like, substitute slightly different lentils from your pantry, but keep in mind different varieties may change final texture. The image below shows a realistic flat-lay of every raw, uncooked ingredient exactly as listed—used together to make this soup.

Preparation Overview

How the recipe comes together—big picture.
Before diving into step-by-step instructions, it helps to understand the assembly: we begin by building flavor through sautéed aromatics, followed by adding legumes and broth to cook under pressure. The sauté stage softens vegetables and teases sweetness; the pressure stage transforms dried legumes into a creamy, spoonable texture. Finally, a quick technique—partial puréeing with an immersion blender—yields a silky body while preserving some whole legumes for pleasing texture contrast.
At the end of the process a simple seasoning check and a touch of acid bring balance. I often finish with chopped herbs to add freshness and color contrast. The optional addition of cured meat can be introduced during the sauté stage to render fat and deepen the savory profile, or stirred in at the end for texture contrast depending on preference.
This overview is meant to orient you: think of the recipe as four acts—sauté, combine, pressure cook, finish. That structure helps you monitor texture changes and make small adjustments for personal taste without altering the core technique. The explicit ingredient list and the full cooking steps are provided in their own sections for precise reference.

Cooking / Assembly Process

Step-by-step Instant Pot method for reliable results.

1. Set the Instant Pot to Sauté and add the olive oil. When hot, add the diced onion, carrots and celery; cook 4–5 minutes until softened.
2. Add the minced garlic, smoked paprika and dried thyme; sauté 30–60 seconds until fragrant.
3. Pour in the split peas and lentils, stir to combine with the vegetables.
4. Add the vegetable broth, bay leaves, salt and pepper. Scrape any browned bits from the bottom of the pot with a wooden spoon.
5. Secure the lid and set the Instant Pot to High Pressure for 15 minutes. Make sure the valve is sealed.
6. When the cook time finishes, allow a natural pressure release for 10 minutes, then carefully quick-release any remaining pressure.
7. Open the lid, remove and discard the bay leaves. For a creamier texture, use an immersion blender to purée part of the soup (or blend 1–2 cups) until you reach desired consistency.
8. Stir in lemon juice if using and adjust seasoning with more salt and pepper to taste. Serve hot topped with chopped parsley and optional diced ham or bacon.

I include the full method here so you have the exact sequencing and settings in one place. When assembling the soup in the Instant Pot, watch the sauté stage for gentle caramelization: a bit of color on the vegetables deepens the final broth flavor. During the pressure stage you’ll notice the pot shifts from lively bubbling to a steadier hush—this is where the legumes hydrate and soften. If you choose to partially purée, work in short bursts and check texture frequently: you want a creamy body, not a uniformly smooth puree. The image below captures the pot mid-cooking—steam, active stirring, and visible transformation of legumes into a soft, thickening mass—so you can see the right moment to move to the finishing steps.

Serving Suggestions

Simple, soulful serving ideas.
Serve this soup straight from the pot into warm bowls with a scattering of fresh parsley for brightness. I often reach for a crusty loaf or a warm roll to mop up the thick broth; a drizzle of good olive oil adds silkiness and a touch of richness. For textural contrast, crisp bread rubbed with garlic or a handful of toasted seeds on top give an attractive crunch against the velvety base.
If you included cooked ham or bacon, place a few pieces on top to anchor each bowl and offer bites of savory intensity. For a vegan finish, a spoonful of plain yogurt or a swirl of coconut yogurt can add creaminess and cooling acidity without overpowering legume flavor. Finishing with lemon juice right before serving brightens the profile and cuts through any lingering heaviness, lifting the herbs and aromatics.
For a composed meal, serve alongside a simple green salad dressed in a tangy vinaigrette. This soup also travels well—pack it into microwave-safe containers and include a wedge of lemon or a small herb pouch so diners can finish with fresh notes when reheating. The goal is to pair textures that complement the soup’s body, keeping the overall experience balanced and inviting.

Storage & Make-Ahead Tips

How to store, reheat, and make this soup ahead of time.
This soup is an excellent candidate for meal prep. Once cooled, transfer portions into airtight containers and refrigerate; flavors often meld and deepen after a day in the fridge. When reheating, add a splash of water or broth to loosen the soup as it will thicken in cold storage. Gentle reheating on the stovetop preserves texture—stir frequently over low heat until warmed through so legumes remain tender but not falling apart further.
For longer storage, freeze the soup in single-portion containers. Label with the date and defrost overnight in the refrigerator before reheating. If the soup was partially puréed before freezing, it will thaw into a creamy consistency; if it was left chunky, you may prefer to purée a portion after reheating to create a silkier mouthfeel. Avoid overheating in the microwave which can concentrate saltiness or dry out the texture; instead, reheat gently and adjust seasoning after warming.
If you plan to make this soup ahead for a gathering, consider cooking it a day in advance and finishing with lemon and fresh parsley just before serving. That final freshening step is essential: acidity and bright herbs revive the bowl and make leftovers taste freshly made.

Frequently Asked Questions

Answers to common reader questions and troubleshooting tips.

• Can I swap lentils or peas? Yes—different lentils will affect texture. Red lentils break down faster and yield a smoother body, while green or brown lentils keep more bite.
• How do I adjust the texture? Partial puréeing with an immersion blender creates a creamier mouthfeel while retaining some whole legumes for texture contrast. Purée off the heat in short bursts and check frequently.
• What if my soup is too thick after chilling? Stir in a little hot water or broth while reheating to reach your preferred consistency. A splash of acid at the end will also lighten the perception of thickness.
• Can I make this on the stovetop? Absolutely—simmer gently until legumes are tender, watching liquid levels and stirring occasionally to prevent sticking. Cook time will be longer than pressure cooking.
• Is this soup freezer-friendly? Yes—portion into airtight containers and freeze. Thaw overnight in the fridge and reheat gently.
