Ingredients
Scale
Steak and Vegetables
- 1 pound steak (such as sirloin or flank steak), cut into bite-sized pieces
- 4 cups potatoes, peeled and sliced (about 4 medium potatoes)
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 2 tablespoons olive oil (for browning the steak)
Sauce and Cheese
- 1 cup beef broth
- 1/2 cup sour cream
- 1 teaspoon Worcestershire sauce
- 1 teaspoon dried thyme
- Salt and pepper, to taste
- 1 cup shredded cheddar cheese
- Fresh parsley, chopped (for garnish, optional)
Instructions
- Brown the Steak: Heat the olive oil in a skillet over medium-high heat. Season the steak pieces with salt and pepper, then sear them for about 3-4 minutes until browned on all sides. Transfer the browned steak to the slow cooker.
- Prepare the Casserole: In the slow cooker, layer the sliced potatoes, chopped onion, and minced garlic evenly over the browned steak. In a separate bowl, whisk together beef broth, sour cream, Worcestershire sauce, dried thyme, and additional salt and pepper. Pour this sauce evenly over the layered ingredients. Sprinkle half of the shredded cheddar cheese on top.
- Cook: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the potatoes are tender and the steak is fully cooked.
- Add Remaining Cheese: About 15 minutes before serving, sprinkle the remaining cheddar cheese over the casserole. Cover and allow the cheese to melt completely.
- Serve: Gently stir the casserole before serving. Garnish with fresh parsley if desired. Serve warm and enjoy your delicious Slow Cooker Steak and Cheddar Potato Casserole.
Notes
- You can use either sirloin or flank steak depending on your preference and availability.
- If you prefer a thicker sauce, reduce the amount of beef broth slightly or cook uncovered for the last 30 minutes to thicken.
- For added flavor, consider adding sliced mushrooms or bell peppers layered with the potatoes.
- Make sure to brown the steak well to lock in flavor before slow cooking.
- This recipe can be made ahead and refrigerated; reheat gently in the slow cooker before serving.
- Use fresh thyme instead of dried for an even more aromatic taste if desired, adjusting quantities accordingly.
