Ingredient Notes
Sirloin steak: Use sirloin steak. Cut it into 1-inch cubes.
Baby potatoes: Use baby potatoes. Halve any larger ones.
Cajun seasoning: Adds bold, spicy flavor.
Step-by-Step Instructions
Step 1: Prepare the Ingredients
Wash the baby potatoes thoroughly and cut any larger potatoes in half. Place the cubed sirloin steak and halved potatoes in a large mixing bowl.
Step 2: Season
Sprinkle the Cajun seasoning evenly over the steak and potatoes. Toss gently until every piece is well coated.
Step 3: Create the Packets
Lay out four large sheets of heavy-duty aluminum foil on a clean work surface. Divide the seasoned steak and potato mixture evenly among the four sheets, placing each portion in the center. Bring the foil edges together and fold them securely to create tightly sealed packets.
Step 4: Slow Cook
Arrange the foil packets inside the slow cooker, keeping them in a single layer when possible. Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours, until the potatoes are fork-tender and the steak is cooked through.
Step 5: Serve
Carefully remove the packets from the slow cooker. Open each packet away from your face to avoid the hot steam. Garnish with chopped parsley and drizzle with melted butter, if desired. Serve immediately with sour cream or ranch dressing.
