Ingredients

• 2 pounds sirloin, flank steak, or round steak, sliced into ½-inch strips
• 3 tablespoons Cajun seasoning
• 6 tablespoons unsalted butter, melted

Directions

Step 1: Prepare the Foil Packets

Cut four large sheets of heavy-duty aluminum foil (about 12–14 inches each). If using regular foil, double each sheet to prevent leaking.

Step 2: Season the Steak

Pat the steak dry with paper towels. Place it in a large bowl and toss thoroughly with the Cajun seasoning until evenly coated. Let it rest for 10–15 minutes for even more flavor if time allows.

Step 3: Assemble the Packets

Divide the seasoned steak evenly among the foil sheets. Drizzle melted butter over each portion.

Step 4: Seal the Packets

Fold the long edges together and crimp tightly. Fold both ends securely to create sealed packets that keep all the flavorful juices inside.

Step 5: Cook

Arrange the packets seam-side up inside the slow cooker.

• LOW: 4–6 hours
• HIGH: 2–3 hours

Cook until the steak is fork-tender.

Step 6: Serve

Carefully open each packet, avoiding the hot steam. Spoon the buttery Cajun juices over the steak and serve immediately.
