Ingredients
For the Steak and Potatoes
| Ingredient | Quantity |
| Beef steak (ribeye, sirloin, or strip steak) | 500–700 g |
| Baby potatoes (Yukon Gold or red potatoes) | 500 g |
| Unsalted butter, cut into pieces | 4–6 tablespoons |
| Garlic powder | 1 teaspoon |
| Onion powder | 1 teaspoon |
| Salt | ½–1 teaspoon, to taste |
| Black pepper | ½ teaspoon |
| Cajun seasoning or Italian seasoning | 1 teaspoon (optional) |
| Smoked paprika | ½ teaspoon (optional) |
Equipment
- Heavy-duty aluminum foil
- Slow cooker (Crockpot)
- Sharp knife and cutting board
- Measuring spoons
Step-by-Step Instructions
Step 1: Prepare the Potato Foil Packets
Wash the baby potatoes thoroughly and cut them in half. If some potatoes are particularly large, cut them into smaller, evenly sized pieces to help them cook uniformly.
Cut several large squares of heavy-duty aluminum foil.
Divide the potatoes between the foil sheets. Season with salt, black pepper, garlic powder, onion powder, and your preferred steak seasoning.
Add a generous piece of butter to each portion of potatoes.
Fold the aluminum foil tightly around the potatoes, sealing the edges to create secure packets that retain moisture and buttery juices.
Step 2: Prepare the Steak
Place a large sheet of heavy-duty aluminum foil on a clean work surface.
Position the beef steak in the center of the foil.
Season both sides generously with salt, black pepper, garlic powder, onion powder, and Cajun or Italian seasoning if desired.
Add a few extra potato pieces around the steak if you like.
Place several pieces of butter directly on top of the steak to add richness and flavor during cooking.
Fold the foil securely around the steak, sealing all edges to prevent the juices from escaping.
Step 3: Cook in the Slow Cooker
Arrange the sealed potato packets and steak packet inside the slow cooker.
Make sure the packets fit comfortably without forcing the lid open.
Cover the slow cooker with its lid. No additional water is needed for the foil packets themselves.
Cook according to your preferred setting:
- LOW: 6–8 hours.
- HIGH: 3–4 hours.
Check that the potatoes are fork-tender and the steak has reached a safe internal temperature.
For whole beef steaks, use a food thermometer to check the thickest part. Follow the recommended safe temperature of 145°F (63°C), followed by a 3-minute rest. Cooking longer may make certain steak cuts drier rather than more tender.
Step 4: Open and Serve
Carefully remove the foil packets from the slow cooker using kitchen tongs.
Open each packet slowly, keeping your hands and face away from the escaping hot steam.
Transfer the steak and potatoes to serving plates.
Slice the steak against the grain, spoon the buttery cooking juices over the meat and potatoes, and serve immediately.
Enjoy this delicious homemade slow cooker steak dinner!
Best Tips for Perfect Results
Choose evenly sized baby potatoes so they cook at approximately the same rate. Heavy-duty aluminum foil is recommended to prevent tearing and leaking.
Avoid overcrowding the slow cooker, and make sure the lid closes properly. Use a meat thermometer rather than relying only on cooking time to determine whether the steak is safely cooked.
Best Ingredient Options
Ribeye offers excellent marbling and a rich flavor, while sirloin and strip steak provide leaner alternatives. Yukon Gold potatoes are especially good because they develop a naturally creamy texture when cooked.
For extra flavor, use fresh minced garlic, smoked paprika, rosemary, or thyme. Unsalted butter gives you better control over the overall saltiness.
Recipe Variations
For a garlic butter version, add freshly minced garlic and chopped parsley to the butter. For a Cajun-style dinner, increase the Cajun seasoning and add smoked paprika. You can also include sliced onions, mushrooms, or bell peppers in the foil packets for additional flavor and vegetables.
What to Serve With This Recipe
Serve these steak and potato foil packs with steamed green beans, roasted broccoli, a fresh garden salad, or buttered corn. Garlic bread is another delicious addition for soaking up the flavorful butter juices.
Make-Ahead Instructions
You can wash and cut the potatoes, prepare the seasoning mixture, and portion the butter several hours ahead of time.
Store the prepared ingredients in separate airtight containers in the refrigerator. Assemble the foil packets shortly before cooking.
For food safety, keep raw beef refrigerated until ready to cook.
Storage Instructions
Transfer leftover steak and potatoes into airtight containers and refrigerate within 2 hours of cooking.
Store in the refrigerator for up to 3–4 days.
Keep the steak and potatoes together or in separate containers, depending on how you plan to reheat them.
Reheating Instructions
For the best results, reheat the steak and potatoes in a covered oven-safe dish at 325°F (165°C) until thoroughly heated.
You can also use the microwave. Place a portion on a microwave-safe plate, cover loosely, and heat in short intervals until hot throughout.
Add a little butter or beef broth if the leftovers seem dry.
Do not place aluminum foil in the microwave.
Freezing Instructions
Allow the cooked steak and potatoes to cool completely before transferring them into freezer-safe containers.
Freeze for up to 2 months for the best quality.
Thaw overnight in the refrigerator before reheating thoroughly.
Keep in mind that potatoes may become slightly softer after freezing and thawing.
Common Mistakes to Avoid
Using potatoes that are too large can result in uneven cooking, so cut them into similar-sized pieces. Another common mistake is failing to seal the foil packets properly, which allows flavorful juices to escape.
Avoid opening the slow cooker repeatedly because this releases heat and increases cooking time. Most importantly, do not assume that the steak is safely cooked simply because the potatoes are tender. Always check the internal temperature with a food thermometer.
