These slow cooker jacket potatoes are incredibly easy and a great alternative to oven-baked spuds. The flesh becomes soft and creamy, so you won’t miss a crunchy skin, and they’re ideal for warm weather or days when you don’t want to heat the oven.
Simple to prepare and naturally vegan and gluten-free, this method suits cooks of all levels. Minimal hands-on time and plenty of versatility make these potatoes perfect for weeknights, parties or casual family meals. Below you’ll find tips, step-by-step instructions and serving suggestions.
Why try slow cooker jacket potatoes?
I used to insist potatoes should only be baked in the oven. Then on a very hot day I needed jacket potatoes without heating my kitchen, so I tried the slow cooker method. I was surprised—these potatoes are soft, creamy and delicious, with almost no prep time. The set-it-and-forget-it approach also makes them ideal for busy midweek schedules.
If you need a quicker option, an air fryer can produce a faster result with crispier skins.
Do the skins crisp up in the slow cooker?
No—slow cooking won’t give the same crisp skin as an oven. If you prefer a crispy finish, you can briefly transfer the potatoes to a hot oven or under a grill to crisp the skins. That said, many people find the creamy texture of slow-cooked potatoes perfectly satisfying without the crunch.
Leave the house and come back to dinner
Slow cooker jacket potatoes are a safe and convenient option if you need to be out while they cook. You don’t need to worry about leaving an oven on, and the slow cooker will have them ready when you return.
Dietary considerations
Potatoes are naturally gluten-free and work well in vegetarian and vegan diets. The toppings you choose will determine allergen content, so select fillings to suit your household’s needs.
What potato variety should I use?
Use whatever potato you prefer or have on hand. Fluffy baking varieties or all-purpose potatoes both work. Choose size and type based on what’s available—most will cook well in the slow cooker.
Does potato size matter?
Size only affects cooking time. Medium potatoes (around 350 g) work well and fit easily in most slow cookers. As long as the potatoes sit in a single layer and fit comfortably, the slow cooker will handle them without risk of overcooking.
Cooking time
For medium potatoes, cook on high for about 3–4 hours or on low for 5–6 hours. Preparation takes just a few minutes. Adjust the time slightly for very small or very large potatoes.
Advantages of slow cooker jacket potatoes

Tips for perfect slow cooker jacket potatoes
- Turn potatoes once during cooking if you’re home to promote even browning.
- For slightly crispier skins, line the slow cooker base with two sheets of baking paper and skip the foil—skins won’t match an oven but will be firmer.
- Don’t overcrowd the cooker; keep a single layer so each potato contacts the base.
- When wrapping in foil, keep the extra foil on one side and place that side down to reduce the risk of burning.
- Use flavored oil (garlic or chili-infused) instead of plain olive oil for extra taste.
Easy Slow Cooker Jacket Potato – Step by Step
(Printer-friendly recipe card is available at the end of the post.)
This recipe uses both UK metric and US measurements.
Ingredients (serves 3)
- Salt
- 1–2 tbsp olive oil
- 3 medium potatoes (approx. 350 g each)
Essential equipment
- Small plate
- Aluminium foil
- Slow cooker (3.5 L recommended; adjust times if yours is larger or smaller)
Instructions
1. Grind some salt onto a small plate. Drizzle a little olive oil over each potato and rub it around to coat the skins, then rub the salt onto each potato.
2. Place each potato in the center of a sheet of foil and fold to wrap, keeping any excess foil on the same side. The side with extra foil should sit on the cooker base to reduce burning.
3. Place the wrapped potatoes in a single layer in the slow cooker, excess foil side down.
4. Cover and cook on high for about 3–4 hours or on low for 5–6 hours, until tender. If you’re around, turning them once helps them brown more evenly.
5. Carefully remove the hot potatoes, unwrap and serve immediately with your favorite toppings, or keep them wrapped and on the warm setting until needed.
