Colcannon is the kind of dish that feels like a hug on a plate: creamy potatoes, a kiss of butter, and bright, softened cabbage woven through. This Instant Pot version shaves off the elbow grease and gives you the same comforting result in far less time. It’s a weeknight-ready side that plays equally well with roast chicken, sausages, or a simple fried egg.

I use shredded green cabbage here because it softens quickly and keeps its mild, slightly sweet flavor. Yukon Gold potatoes mash beautifully — they’re waxy enough to stay silky, but starchy enough to absorb cream and butter. The finish is straightforward: a final mash, a taste, and small seasoning adjustments if needed.

Below you’ll find a direct ingredient list and step-by-step Instant Pot instructions that follow the recipe exactly. I’ll also cover useful swaps, common mistakes and how to avoid them, and simple reheating and storage guidance so you can make this reliably every time.

Ingredient Rundown

Ingredients

1 tablespoon olive oil — Used for sautéing the cabbage so it softens and develops flavor before pressure cooking.
2 cups shredded green cabbage — The cabbage in colcannon; adds texture, color, and a mild sweetness.
2 cloves garlic, minced — Provides aromatic depth; mince finely so it disperses through the mash.
2 pounds Yukon gold potatoes, peeled and cut into 1-inch cubes — The main body of the dish; Yukon Golds mash smoothly and taste buttery on their own.
3/4 cup water — Adds the steam needed for the potatoes and cabbage to cook under pressure.
1/2 cup heavy cream — Makes the mash rich and silky; adds moisture so the texture is creamy without being gluey.
4 tablespoons unsalted butter, divided — Fat for flavor and mouthfeel; half is cooked with the vegetables, the rest is stirred in at the end.
1 teaspoon kosher salt — Base seasoning in the cooking liquid; polishes the potatoes and cabbage as they cook.
1/2 teaspoon black pepper — A straightforward finish spice; adds warmth without overpowering.

Build Instant Pot Colcannon Potatoes Step by Step

Select the Sauté function on the Instant Pot and set it to High. Add 1 tablespoon olive oil and heat about 1 minute, until the oil shimmers.
Add 2 cups shredded green cabbage and cook, stirring occasionally, until softened, about 5 minutes.
Add 2 cloves minced garlic and cook, stirring, for 1 minute.
Add 2 pounds peeled and 1-inch cubed Yukon Gold potatoes, 3/4 cup water, 1/2 cup heavy cream, 2 tablespoons unsalted butter (from the 4 tablespoons), 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Stir to combine.
Press Cancel to stop Sauté. Close and lock the lid, and set the steam release valve to the “Sealing” position. Select Pressure Cook (High) / Manual and set the time to 7 minutes.
When the cook time ends, perform a quick release by carefully moving the valve to “Venting.” Keep hands and face away from the steam; wait until the float valve drops before opening the lid.
Open the lid, add the remaining 2 tablespoons unsalted butter, and mash the potatoes and cabbage to your desired consistency using an immersion blender, hand masher, or stand mixer.
Taste and adjust seasoning with additional salt and/or pepper if needed. Serve hot.
Store any leftovers in an airtight container in the refrigerator for up to two days.

The Upside of Instant Pot Colcannon Potatoes

This method trims active time and reduces the need to babysit a pot of boiling spuds. The cabbage sautéd first develops a little sweetness and keeps its green color, then it melds with the potatoes under pressure. You get a one-pot finish with less cleanup.

Texture is easy to control here. You can stop at rustic lumps or go velvety smooth depending on your tool — masher, immersion blender, or stand mixer. And because the potatoes cook right in the Instant Pot with cream and butter, the result is rich without extra steps.

Budget & Availability Swaps

Yukon Golds are ideal, but when they’re pricier or scarce, use any all-purpose potato you prefer — red potatoes or white potatoes work. Stay away from very high-starch Russets if you want a silky mouthfeel; they can absorb more liquid and become gluey if overworked.

If heavy cream is an expense, you can thin with whole milk for similar results, though the finish will be slightly less rich. Olive oil can be swapped for neutral oil or a small amount of bacon fat if you want a smoky note (and you have it on hand).

Hardware & Gadgets

Instant Pot: Any 6-quart or similar multicooker with Sauté and Pressure Cook functions will work.

For mashing: pick based on desired texture. A sturdy hand masher keeps things rustic. An immersion blender gives you smooth, restaurant-style creaminess — but use short bursts to avoid gummy potatoes. A stand mixer yields ultra-silky results with minimal effort.

Pitfalls & How to Prevent Them

1) Watery or thin mash

If you find the mash too loose, mash less vigorously and let the dish sit off heat for a few minutes; residual heat thickens it slightly. If it’s significantly thin, add a small extra pat of butter or a tablespoon of instant mash granules to tighten it up.

2) Gummy potatoes from overworking

Over-pureeing hot potatoes, especially in a blender, releases more starch and produces a gluey texture. Use a hand masher for a rustic feel, or an immersion blender in short bursts for creamier results without going gummy.

3) Cabbage that loses color or flavor

Sautéing the shredded cabbage first softens it and locks in flavor. Don’t overcook it until it’s brown; you just want it softened and slightly sweetened before adding the potatoes.

Substitutions by Diet

Vegan: Replace heavy cream with unsweetened plant milk (oat or cashew are best for creaminess) and use vegan butter or olive oil in place of unsalted butter. Skip the dairy adjustments in step order; proceed the same way.

Lactose-sensitive: Use lactose-free cream or lactose-free milk with a little extra butter substitute to approximate the mouthfeel.

Lower-fat: Swap heavy cream for whole milk or a mix of milk and Greek yogurt (stir the yogurt in off-heat to prevent curdling). Expect a lighter texture and slightly tangy note from yogurt.

Low-sodium: Reduce the salt in the recipe and taste before serving. If serving alongside salty mains (like sausages), you can omit the added salt and adjust at the table.

If You’re Curious

Colcannon is an Irish classic traditionally made with mashed potatoes and cabbage or kale, often with scallions and butter. It’s a humble dish — built to stretch simple ingredients into something comforting and flavorful. Here, the Instant Pot streamlines the cooking timeline while honoring that simplicity.

Flavor-wise, the cabbage adds a fresh counterpoint to the richness of butter and cream. If you want to echo tradition, sprinkle chopped scallions or chives on top at the end. A few crispy bacon bits work if you don’t need the dish to be vegetarian.

Refrigerate, Freeze, Reheat

Refrigerate leftovers in an airtight container for up to two days, per the recipe directions. Reheat gently on the stovetop over low heat with a splash of milk or cream and a pat of butter to restore creaminess. Stir frequently to prevent sticking.

I don’t recommend freezing this exact preparation if you want the best texture. The cream and butter can change texture after thawing and reheating. If you need to freeze, do so knowing the final texture will be a bit grainier; thaw overnight in the refrigerator and reheat slowly with added liquid to smooth it out.

Your Top Questions

Q: Can I skip the sauté step?

A: You can, but sautéeing the cabbage first softens it and brings out a mild sweetness. Skipping it will save a few minutes but give you a slightly underdeveloped cabbage flavor.

Q: What if I don’t have an immersion blender?

A: A hand masher or stand mixer works fine. If you use a stand mixer, transfer the hot mixture carefully and use the paddle attachment on low to avoid overworking the potatoes.

Q: Is quick release necessary?

A: The recipe calls for a quick release. That stops further cooking and helps prevent the cabbage from becoming slimy. Always keep hands and face clear of steam when venting.

Q: Can I add scallions, leeks, or kale?

A: Yes. Scallions can be stirred in at the end for a fresh bite. Leeks can be sautéed with the cabbage. Kale is heartier than cabbage and can be added, but chop it finely so it softens quickly.
