Rumbledthumps–a tasty potato and cabbage side dish that you can make in the Instant Pot or slow cooker.

Rumbledthumps
Rumbledethumps is a traditional Scottish dish made up of mashed potatoes and cabbage. The name is believed to derive from the Scottish words “rumble” (to mix or stir) and “thump” (to mash or pound), reflecting the preparation method. Basically it’s mashed potatoes and cabbage with cheese on top and it’s so yummy! I wanted to eat the whole batch.
Ingredients/Substitution Ideas
- Chicken broth–or water and Better than Bouillon chicken base
- Cabbage
- Russet potatoes–or yukon gold potatoes
- Butter
- Kosher salt
- Black pepper
- Cheddar cheese–I like sharp
- Chives–or green onions
Steps
Add broth into Instant Pot. Add cabbage evenly into bottom of the pot. Then add the potatoes on top.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 5 minutes. When time is up move valve to venting and remove the lid.

Drain the broth. Add in the butter and mash the potatoes and cabbage. Stir in the salt and pepper.

Sprinkle the cheese on top and let it melt or you can stir it in. Top with chives and serve.

Notes/Tips
- Serve as a side dish like you would serve mashed potatoes.
- I used my 6 quart Instant Pot*. You can also make this in an 8 quart pot or halve the recipe in a 3 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- Other recipes you can make with cabbage are Instant Pot Panda Express Chow Mein and Instant Pot Korean BBQ Burrito.
