Ingredients
- 8 Irish sausages or pork sausages
- 2 large onions, sliced
- 1 can beef broth or beef consommé (about 14 oz)
- 1 packet onion soup mix
That’s it. Just four simple ingredients for one incredibly flavorful dinner.
Step-by-Step Method
Step 1: Slice the Onions
Slice the onions into thick strips and place them in the bottom of the slow cooker.
I usually use sweet onions because they become extra rich and caramelized during cooking.
Step 2: Add the Sausages
Place the sausages on top of the onions in an even layer.
You can brown them first in a skillet if you want extra color, but honestly, I sometimes skip that step on busy days.
Step 3: Add the Flavor
Sprinkle the onion soup mix evenly over the sausages and onions.
Pour the beef broth over everything.
Step 4: Slow Cook Until Tender
Cover and cook:
- LOW for 6–8 hours
or - HIGH for 3–4 hours
The onions will become soft and flavorful, and the sausages will stay juicy and tender.
