Dumplings in a slow cooker usually take about 45–90 minutes to cook once your stew or filling is already hot and simmering on high.

Quick Scoop

  • On HIGH : Most dough dumplings (on top of a hot stew) take 45–60 minutes.
  • On LOW : Plan for 60–90 minutes , especially if your cooker runs cooler.
  • For canned biscuit-style dumplings: often about 45 minutes on HIGH , longer (up to 1.5 hours) if the slow cooker has switched to warm first.
  • For suet or flour dumplings on stews/mince: usually added for the last 45–60 minutes of the overall cook time.

How to tell they’re done

Use these simple checks so you don’t have to guess:

  • Dumplings look puffed and no longer shiny on top.
  • A toothpick or skewer in the center comes out clean, with no wet dough.
  • When you cut one open, the middle is cooked through and fluffy, not dense or gummy.

Mini timing guide by setting

[9][5][3] [5][1]
Slow cooker settingTypical dumpling time (once stew is hot)
High heat45–60 minutes for most drop/suet dumplings or canned biscuits.
Low heatAbout 60–90 minutes, depending on size and cooker.

Tip: Try not to lift the lid while they cook; losing heat can add 15–30 minutes to the time.

Short version: Once your stew or filling is fully hot, add dumplings on top, cover, and cook on HIGH for about 45–60 minutes or LOW for about 1–1.5 hours , then test the center of one to be sure it’s cooked through.
