How to Make Slow Cooker Garlic Butter Potatoes and Onions
Step 1: Prepare the Slow Cooker
Lightly grease the inside of your slow cooker with butter or cooking spray.
This helps prevent sticking and makes cleanup easier.
Step 2: Mix the Garlic Butter
In a small bowl, whisk together:
- Melted butter
- Garlic
- Salt
- Black pepper
- Italian seasoning
- Paprika
Mix until well combined.
Step 3: Layer the Potatoes
Arrange half of the sliced potatoes in the slow cooker.
Top with half of the sliced onions.
Repeat with the remaining potatoes and onions.
Step 4: Add the Liquid
Pour the broth around the edges of the slow cooker.
Drizzle the garlic butter mixture evenly over the layered potatoes.
Step 5: Slow Cook
Cover with the lid.
Cook on:
- Low: 5 to 6 hours
- High: 3 to 4 hours
The potatoes should be fork-tender and the onions soft and sweet.
Step 6: Finish and Serve
Carefully stir everything together so the potatoes are coated in the buttery cooking juices.
Sprinkle with fresh parsley before serving if desired.
