Vegetarian Split Pea Soup Instant Pot Recipe (GUIDE)

There’s something incredibly comforting about a bowl of soup, especially when it’s warm, hearty, and full of flavor. Split pea soup holds a special place in my heart. I remember the first time I tried it, many years ago, at a cozy little café in a small town I was passing through. The thick, velvety texture, with just the right amount of smokiness and earthiness from the peas, was unlike anything I’d had before. It instantly became one of my go-to comfort foods.

Over time, I’ve played around with various ways to make split pea soup, and it turns out, the Instant Pot is a game-changer when it comes to preparing this dish. Not only does it save time compared to traditional stove-top cooking, but it locks in all those rich flavors, allowing the peas to break down perfectly and create that velvety texture without hours of simmering.

Vegetarian Split Pea Soup Instant Pot Recipe

Here’s the thing about split pea soup: it’s deceptively simple. A few ingredients, a good dose of patience, and you end up with a thick, satisfying soup that feels like a full meal. The best part is that it doesn’t need any meat to achieve that rich, hearty flavor. The Instant Pot speeds up the process, so you can enjoy this comfort food any day of the week without waiting hours.

Here’s how you make it:

Ingredients Needed

• 1 ½ cups dried green split peas
• 1 tablespoon olive oil (or any oil you prefer)
• 1 medium onion, chopped
• 2 large carrots, chopped
• 2 celery stalks, chopped
• 3 cloves garlic, minced
• 1 teaspoon dried thyme
• 1 bay leaf
• 6 cups vegetable broth (or water for a lighter option)
• 1 teaspoon salt (or to taste)
• ½ teaspoon black pepper
• 1 teaspoon smoked paprika (optional, but adds a lovely depth of flavor)
• Juice of half a lemon (for brightness)
• Fresh parsley, for garnish

Cooking Instructions

1. Prepare the Vegetables: Start by prepping your veggies-chop the onion, carrots, and celery into bite-sized pieces. Mince the garlic. This is the part where I love the rhythm of chopping. There’s something meditative about it that sets the tone for the meal.
2. Sauté the Veggies: Turn your Instant Pot to the ’Sauté’ function. Add the olive oil. Once it’s hot, toss in the onions, carrots, and celery. Sauté for about 5-6 minutes, until the veggies start to soften. The kitchen will begin to smell amazing, and you’ll know you’re on the right track. Add the garlic and cook for another minute or two. The garlic should get fragrant, but be careful not to burn it.
3. Add the Spices and Split Peas: Now, toss in the dried split peas, thyme, bay leaf, smoked paprika (if using), salt, and pepper. Stir to combine everything together.
4. Pour in the Broth: Add the vegetable broth, stirring once more to ensure everything is evenly distributed. I love using a good-quality vegetable broth because it really infuses the soup with extra flavor.
5. Pressure Cook: Secure the Instant Pot lid, make sure the valve is set to “Sealing”, and cook on high pressure for 15 minutes. It’s amazing how quickly it all comes together! Once the time’s up, let the pressure naturally release for about 10 minutes, then carefully turn the valve to “Venting” to release any remaining pressure.
6. Finish and Serve: Open the Instant Pot and remove the bay leaf. You’ll have a thick, creamy soup with tender peas. If you like a smoother texture, you can use an immersion blender to blend it directly in the pot, or transfer part of the soup to a blender and puree it. I usually like to keep a bit of texture for that rustic feel.
7. Garnish and Enjoy: Before serving, squeeze the juice of half a lemon into the soup and stir well. The lemon adds a fresh, zesty contrast that really elevates the flavors. Ladle into bowls, garnish with fresh parsley, and dig in.

Ingredient Science Spotlight

Every ingredient in this soup brings its own little magic to the table. Let’s talk about the split peas for a moment-these tiny legumes are powerhouses of nutrition. Packed with plant-based protein, fiber, and essential vitamins like folate, they’re an incredible addition to any diet. The peas also act as a natural thickener for the soup, creating that satisfying, creamy texture without needing any cream or butter.

The carrots and celery contribute not only to the soup’s sweetness and flavor but also add vitamins and minerals-particularly vitamin A from the carrots. Garlic, of course, offers its immune-boosting properties, while thyme and bay leaf give the soup its herbal, slightly earthy undertones. Smoked paprika, if you decide to use it, adds a smokiness that deepens the soup’s flavor, making it feel almost like it’s been slow-cooked over a fire for hours. That depth and complexity is just delightful.

Expert Tips

1. Rinse the Split Peas: It’s a small step, but rinsing your split peas under cold water before cooking helps remove any debris or dust, ensuring the soup will have a cleaner flavor.
2. Consistency is Key: If you prefer a thicker soup, use less liquid. If you like it a bit more brothy, feel free to add a little more vegetable broth or water. You can always adjust to your desired consistency after the pressure cooking.
3. Add More Flavor Layers: Don’t be afraid to play with your spices! A little cumin or curry powder can take this soup to new levels, adding some warmth and richness. Or, if you like a little heat, a pinch of cayenne pepper or chili flakes can do wonders.
4. Use a Homemade Broth: If you have time, homemade vegetable broth can take this soup to the next level. The flavors meld so much better, and you can control the seasoning more effectively.

Recipe Variations

1. Lentil Split Pea Soup: If you don’t have split peas, you can easily swap in dried green or brown lentils. They cook a bit faster and give a similar texture, though they won’t absorb the flavors quite as much as split peas.
2. Add Greens: Spinach, kale, or Swiss chard would be a lovely addition to this soup. Toss in a handful toward the end of cooking, just before serving, and let them wilt into the hot soup.
3. Creamy Split Pea Soup: If you like a richer, creamier soup, you can blend some of the soup and add a bit of coconut milk, cashew cream, or a dollop of yogurt to give it a smooth, velvety finish.
4. Herb Swap: If thyme and bay leaf aren’t your thing, try rosemary or sage for a more aromatic and earthy vibe.
5. Smoky Variation: For a smoky kick, you can add a bit of liquid smoke or throw in a couple of smoked sun-dried tomatoes while cooking.

Final Words

Split pea soup, especially when made in the Instant Pot, is a wonderful example of how a few simple ingredients can create a deeply satisfying dish. It’s nourishing, comforting, and, best of all, it doesn’t take a lot of time to make. The Instant Pot truly does the heavy lifting, allowing you to enjoy the fruits of your labor much faster than traditional methods. Whether you’re serving it as a meal on its own or as part of a larger spread, it’s guaranteed to be a hit.

FAQs

Can I Make Vegetarian Split Pea Soup In The Instant Pot Without Soaking The Peas?

Yes, you can make vegetarian split pea soup in the Instant Pot without pre-soaking the peas. The pressure cooking function of the Instant Pot softens the peas quickly, typically in about 15-20 minutes under high pressure. However, if you prefer a smoother texture or want to reduce cooking time slightly, soaking the peas for a few hours or overnight can help.

What Vegetables And Seasonings Work Best For Vegetarian Split Pea Soup In An Instant Pot?

Common vegetables for a rich and flavorful vegetarian split pea soup include carrots, celery, onions, and garlic. You can also add potatoes, leeks, or parsnips for extra heartiness. Seasonings such as thyme, bay leaves, smoked paprika, black pepper, and a pinch of cumin enhance the flavor. A splash of apple cider vinegar or lemon juice at the end brightens the soup. Adjust salt carefully, as some Instant Pot recipes concentrate flavors during pressure cooking.

Can I Make A Creamy Vegetarian Split Pea Soup In The Instant Pot Without Using Dairy?

Yes, you can achieve a creamy texture without dairy. After pressure cooking, simply blend part or all of the soup using an immersion blender or countertop blender. Coconut milk, cashew cream, or unsweetened plant-based milk can be added to enrich the soup further. Blending also helps thicken the soup naturally, giving it a smooth, comforting consistency similar to traditional creamy versions.
