Ingredients
- 2 lbs yellow potatoes, sliced into thick rounds
- 2 medium yellow onions, thinly sliced
- 4 tablespoons unsalted butter, cut into small pieces
- 3 cloves garlic, minced
- 1 cup beef broth
- 2 tablespoons olive oil
- 1 teaspoon paprika
- 1 teaspoon Italian seasoning
- ½ teaspoon garlic powder
- ½ teaspoon black pepper
- 1 teaspoon salt, or to taste
- 2 tablespoons fresh parsley, chopped
Instructions
- Prepare the Potatoes: Wash the potatoes thoroughly and slice them into evenly sized rounds, about ½ inch thick.
- Slice the Onions: Peel and thinly slice the yellow onions. Mince the fresh garlic.
- Layer in the Slow Cooker: Lightly grease the slow cooker. Add a layer of sliced potatoes, followed by sliced onions. Repeat until all the vegetables are arranged inside.
- Add the Seasonings: Sprinkle the minced garlic, paprika, Italian seasoning, garlic powder, salt, and black pepper evenly over the potatoes and onions.
- Add Butter and Broth: Drizzle olive oil over the vegetables. Distribute the butter pieces across the top, then pour in the beef broth.
- Slow Cook: Cover and cook on LOW for 5–6 hours or HIGH for 2½–3½ hours, until the potatoes are fork-tender.
- Finish and Serve: Gently stir the potatoes to coat them with the delicious garlic butter juices. Sprinkle with fresh parsley and serve warm.
Notes
- Yukon Gold or yellow potatoes work especially well because they hold their shape while becoming tender.
- Cut the potatoes into similar-sized slices for even cooking.
- For a vegetarian version, substitute vegetable broth for beef broth.
- Add extra butter or fresh garlic for a richer flavor.
- Avoid stirring too often during cooking to prevent the potatoes from breaking apart.
