How to Make Slow Cooker Beef and Potato Casserole
This slow cooker beef and potato casserole is a marvel of simplicity, requiring minimal hands-on time for maximum flavor. The slow cooker gently coaxes out the best from the ingredients, resulting in fork-tender beef and perfectly cooked potatoes swimming in a deeply savory, almost decadent gravy. With a total preparation time of about 20 minutes, this satisfying dish becomes a realistic option even on your busiest days, promising a warm and hearty meal with minimal fuss.
Step-by-Step Instructions
- Prepare the Beef: In a medium bowl, toss the cubed beef chuck roast with the all-purpose flour, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Ensure each piece of beef is lightly coated.
- Sear the Beef: Heat the olive oil in a large skillet over medium-high heat. Add the floured beef in batches, ensuring not to overcrowd the skillet, and sear on all sides until nicely browned. This step is crucial for developing a rich flavor in the casserole. Remove the seared beef from the skillet and place it into your slow cooker.
- Sauté Aromatics: In the same skillet (no need to clean), add the chopped onion and cook over medium heat until softened and lightly browned, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Transfer the sautéed onion and garlic to the slow cooker with the beef.
- Add Liquids and Seasonings: Pour the beef broth into the slow cooker. Add the Worcestershire sauce, dried thyme, dried rosemary, the remaining 1/2 teaspoon of salt, and the remaining 1/4 teaspoon of black pepper. Stir everything together to combine.
- Cook the Beef: Cover the slow cooker and cook on LOW for 6-8 hours, or on HIGH for 3-4 hours, until the beef is very tender and easily shreds with a fork.
- Add Potatoes: Once the beef is tender, add the cubed Yukon Gold potatoes to the slow cooker. Stir them into the liquid, ensuring they are mostly submerged. If using, add the frozen peas now as well.
- Finish Cooking: Cover the slow cooker again and continue to cook on HIGH for another 1-2 hours, or until the potatoes are fork-tender and cooked through, and the sauce has thickened slightly. The residual heat will cook the potatoes beautifully.
- Serve: Carefully ladle the slow cooker beef and potato casserole into bowls. Garnish with fresh parsley if desired before serving.

To reheat, you have a couple of excellent options. For a single serving, transfer a portion to a microwave-safe dish and heat on medium power, stirring occasionally, until heated through. For a larger amount, you can reheat it in a saucepan over medium-low heat, stirring frequently to prevent sticking and ensure even heating. You can also reheat it gently in a preheated oven at 325°F (160°C) for about 20-30 minutes, covered, until heated through. If you’d like to freeze portions for future meals, allow the casserole to cool completely, then portion it into freezer-safe containers or heavy-duty freezer bags. It will keep well in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating using one of the methods described above.
