Ingredients for pea soup instant pot
Fresh peas, aromatic vegetables, and a touch of coconut milk create restaurant-quality soup in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh or Frozen Peas 🌱 | 2 cups | Thawed if frozen, no need to peel |
| Yellow Onion 🧅 | 1 whole | Medium size, diced finely |
| Carrots 🥕 | 2 medium | Peeled, chopped into small pieces |
| Celery Stalks 🥬 | 2 whole | Trimmed, chopped into small pieces |
| Potatoes 🥔 | 1 lb | Russet or Yukon gold, peeled, cubed |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred, homemade or store-bought |
| Fresh Thyme 🌿 | ½ tsp | Dried thyme at one-third amount |
| Garlic Cloves 🧄 | 3 cloves | Peeled, minced finely |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Sea Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Coconut Milk 🥥 | ½ cup | Full-fat for creaminess (optional) |
| Unsalted Butter 🧈 | 2 tbsp | For finishing (optional) |
The peas are the star, so fresh or high-quality frozen is essential—avoid mushy or discolored peas. Trader Joe’s and Costco carry excellent frozen options in bulk, which saves money and keeps well. For the potatoes, Yukon gold yields the creamiest texture, but russet works fine if that’s what’s on hand. The carrots and celery should be firm with vibrant color—no limp or rubbery stalks. Fresh thyme is ideal, but dried works at one-third the amount if you’re in a pinch. Garlic should be fresh, with a strong aroma when peeled.
No vegetable broth? Homemade veggie stock or even water with bouillon cubes works, though flavor will be milder. Swap coconut milk for Greek yogurt or extra cream—just reduce the broth by 0.25 cups to compensate. The olive oil matters here—extra-virgin adds fruity depth, while regular vegetable oil is fine for basic flavor. For extra richness, stir in butter or cream cheese at the end. The parsley is purely decorative, but it brightens the dish beautifully. If you’re vegan, omit the butter and use more coconut milk instead.
This soup reheats beautifully—simply add a splash of broth or water if it thickens. Store in an airtight container for 4-5 days in the fridge or freeze for up to 3 months. For meal prep, double the recipe and portion into containers. The flavors actually improve overnight as everything melds together. Garnish with fresh herbs or a drizzle of olive oil just before serving to keep it vibrant.
Why You’ll Love This Recipe
- No-Chop Shortcut: I swear by frozen peas here—no wilting, no waste, and they’re already prepped. Toss in chopped onion, carrots, and celery (or just rough-chop if you’re lazy), dump it all in the Instant Pot, and let it do the work. Twenty minutes later, you’ve got a soup that feels homemade.
- Creamy Without Cream: Here’s what sold me—the potatoes break down into that velvety texture while the peas stay bright and snappy. A splash of broth, a pinch of thyme, and you’ve got a rich, satisfying bite that’s oddly addictive (yes, even on a Tuesday night).
- Lunchbox Magic: Between us, this soup reheats like a dream and tastes just as good cold. Pack it in jars for work lunches or school lunches—kids will eat the veggies without complaining. My daughter picks out the peas, but still asks for seconds.
- Pantry Staple Power: Honestly, this recipe won’t break the bank. Onions, carrots, celery, and potatoes? They’re cheap, shelf-stable, and you’ll use them up before they spoil. Plus, the leftovers keep for days—freeze half for when you’re too tired to cook.
Step-by-step instructions for pea soup in the Instant Pot
Here’s the method for a velvety, restaurant-quality pea soup that comes together in minutes.
Sauté the Aromatic Vegetables
Set your Instant Pot to “Sauté” mode and add the 2 tablespoons olive oil. Once hot, add the 1 whole yellow onion, 2 medium carrots, and 2 whole celery stalks, all chopped into small pieces. Cook for 5-6 minutes until the vegetables soften and the onion becomes translucent, stirring occasionally.
This step builds the flavor foundation. The vegetables should release their moisture and develop a slight caramelization—watch for the edges to turn just slightly golden. If using frozen peas, there’s no need to thaw them first. Add the 2 cups fresh or frozen peas along with the 3 cloves minced garlic and 0.5 teaspoon fresh thyme to the pot and stir for 1 minute to coat everything in the aromatics.
Add Potatoes and Broth
Peel and cube the 1 pound potatoes into 1-inch pieces before adding them to the Instant Pot. Pour in the 4 cups vegetable broth and stir gently to combine. The potatoes should be fully submerged in the liquid. Sprinkle in the 1.5 teaspoons sea salt and 0.5 teaspoon black pepper, giving everything a final mix.
Here’s where the magic happens: the potatoes will break down into the broth, creating a thick, creamy base. The peas will soften just enough to blend seamlessly into the soup, avoiding that mushy texture you sometimes get with overcooked peas. If you prefer a smoother texture, you can mash a few potato pieces with a fork before adding them to the pot.
Pressure Cook for Perfect Texture
Secure the lid on the Instant Pot and set the valve to “Sealing.” Cook on High Pressure for 8 minutes. This short cooking time ensures the peas remain vibrant and the potatoes break down just enough to create a thick, velvety texture without turning to mush.
Once the cooking time is complete, allow the pressure to release naturally for 10 minutes before using the quick-release function. This gradual release prevents the soup from becoming watery. After the quick release, open the lid and stir the soup gently. If the texture is thicker than you prefer, you can add 1-2 tablespoons water to adjust the consistency.
Finish with Creaminess and Garnish
Stir in the 0.5 cup coconut milk and 2 tablespoons unsalted butter to add richness and depth of flavor. The coconut milk will blend smoothly, giving the soup a luxurious, velvety finish. Taste and adjust the seasoning if needed—you may need a bit more salt or pepper depending on your broth.
Ladle the soup into bowls and garnish with the 0.25 cup chopped fresh parsley. The parsley adds a bright, fresh contrast to the creamy soup and makes it visually appealing. Serve immediately while hot, as the flavors continue to develop as the soup sits.
Pro Tips For Making Pea Soup Instant Pot
- CHOP VEGGIES EVENLY: I learned this the hard way—uneven pieces mean some carrots and celery stay crunchy while potatoes turn to mush. Dice onions into ¼-inch chunks, slice carrots into ½-inch rounds, and cut celery into ½-inch pieces. Potatoes should be 1-inch cubes, no smaller, or they’ll dissolve into the broth.
- SWEAT ONIONS FIRST: Skip the Instant Pot sauté? Don’t. Brown the onions in a dry pot for 3-4 minutes before adding broth—this deepens their flavor. If you’re short on time, at least stir them in the Instant Pot on high heat for 2 minutes before pressing “soup” to build a little base.
- USE HALF THE LIQUID: Pea soup should coat a spoon, not drown it. Start with 2 cups broth (not 4) and add more only if needed after cooking. Frozen peas release water, so you’ll likely need less than you think—taste as you go.
- DON’T SKIP THE STARCH: Mash 1-2 potatoes against the side of the pot before pressing “soup” to thicken the broth naturally. This isn’t just lazy—it’s how your soup goes from watery to velvety. If you forget, blend a handful of cooked potatoes at the end.
Flavor customization for pea soup instant pot
Spicy Kick
Add ½ teaspoon red pepper flakes or 1 tablespoon hot sauce (like Franklin’s Original RedHot) to the broth before pressure cooking for a subtle heat. For extra spice, stir in 1 teaspoon gochujang or ½ teaspoon cayenne pepper after cooking.
Balance the heat with a splash of coconut milk or a dollop of Greek yogurt on top. 🌶️
Herb Infusions
Swap thyme for fresh dill (add 1 tablespoon after cooking) for a bright, tangy twist that pairs beautifully with peas. Or try rosemary (add ½ teaspoon during sautéing) for an earthy, piney depth.
For a Mediterranean touch, add 1 teaspoon dried oregano with the thyme. Fresh herbs like parsley or basil should always be added at the end to preserve their vibrancy.
Umami Boost
Enhance the savory depth with 1 tablespoon soy sauce or 1 teaspoon miso paste stirred into the broth. For a richer flavor, add 1 teaspoon nutritional yeast after cooking—it adds a cheesy, nutty note without dairy.
A splash of fish sauce (just ½ teaspoon) works wonders for umami, though it’s not vegan. 💡
Creamy Variations
For a lighter creaminess, blend in ½ cup silken tofu after cooking for a vegan option. Or stir in ¼ cup crème fraîche for a tangy, velvety finish. If you love cheese, top with shredded Gruyère or Parmesan—just 2 tablespoons adds a luxurious touch.
For a dairy-free alternative, use cashew cream (blend ½ cup soaked cashews with ¼ cup water).
Smoky Depth
Add ½ teaspoon smoked paprika or ¼ teaspoon liquid smoke to the broth for a subtle smokiness. For a bolder flavor, char ½ of the onion in a dry pan before sautéing—this adds a deep, caramelized richness.
A drizzle of chipotle oil (just ½ teaspoon) at the end elevates the dish to smoky perfection. 🔥
Sweet Contrast
Balance the earthy flavors with a touch of sweetness. Stir in 1 teaspoon honey or maple syrup after cooking for a subtle sweetness. For a unique twist, add ½ cup diced apple or pear during sautéing—they’ll soften beautifully and add a fruity brightness.
A sprinkle of toasted coconut flakes on top adds crunch and sweetness in one step.

Frequently asked questions
Can I make this pea soup in a regular pot instead of an Instant Pot?
Yes! Simmer all ingredients in a pot over medium-low heat for 20-25 minutes until potatoes are tender. The texture will be slightly thicker since you won’t have pressure cooking. For extra creaminess, mash a few potatoes before adding broth.
How do I make this recipe vegan?
Swap the vegetable broth for vegan broth, use olive oil instead of butter, and replace coconut milk with cashew cream or silken tofu. Keep the same cooking method—everything else remains identical. The soup stays just as rich and velvety!
Why did my soup turn out watery?
Watery soup usually means the potatoes didn’t break down enough. Try mashing half the potatoes before adding broth next time, or reduce the broth by ½ cup. Also, ensure you used 1 lb potatoes—smaller potatoes may not thicken the soup sufficiently.
Can I use canned peas instead of fresh or frozen?
Drain and rinse 2 cups canned peas before adding to the pot. They’ll work just as well—no need to adjust cooking time. For extra flavor, add ½ teaspoon lemon juice to brighten the taste. The texture will be slightly firmer than fresh peas.
How long will this soup keep in the fridge?
Store in an airtight container for 4-5 days in the fridge. The flavors actually improve as it sits! For leftovers, reheat on Sauté mode in the Instant Pot with 1-2 tablespoons water to restore creaminess. Freeze for up to 3 months if needed.
