Ingredient Notes & Details

Steak

Choose sirloin steak, chuck steak, or round steak for the best balance of tenderness and affordability. Sirloin stays juicy while chuck becomes exceptionally tender after slow cooking. For this baked steak recipe alternative made in the slow cooker, cut the meat into evenly sized cubes to ensure consistent cooking.

Baby Potatoes

Baby Yukon Gold or baby red potatoes work beautifully because they become creamy and buttery as they cook. Their thin skins also eliminate the need for peeling, making preparation even faster. While this isn’t an oven roasted potato recipe, the potatoes develop a rich, buttery texture that’s equally satisfying.

Cajun Seasoning

A quality Cajun seasoning blend provides everything needed—paprika, garlic, onion, cayenne, herbs, and spices. If you’re sensitive to heat, choose a mild blend. For extra spice lovers, use a hotter Cajun seasoning or sprinkle in additional cayenne pepper.

Step-by-Step Instructions

Prepare the Ingredients

Wash the baby potatoes thoroughly and cut any larger ones in half. Slice the steak into bite-sized pieces so they cook evenly throughout the slow cooking process.

Allow the steak to sit at room temperature for about 15 minutes before seasoning. This helps it cook more evenly.

Season Generously

Place the steak and potatoes into a large mixing bowl.

Sprinkle the Cajun seasoning evenly over everything.

Toss until every piece is completely coated with seasoning.

The potatoes should have an even reddish coating, and the steak should appear well-seasoned on every side.

Create the Packets

Lay out large sheets of heavy-duty aluminum foil.

Divide the steak and potato mixture evenly among the sheets.

Fold the foil tightly into sealed packets, making sure no steam can escape during cooking.

The sealed packets trap moisture, allowing everything to become incredibly tender.

Arrange Inside the Slow Cooker

Place the sealed foil packets into the slow cooker in a single layer if possible.

Avoid overcrowding so heat can circulate around each packet.

Cover with the slow cooker lid.

Cook Low and Slow

Cook on LOW for 6–7 hours.

If you’re short on time, cook on HIGH for approximately 3–4 hours.

The steak should be fork-tender, and the potatoes should easily pierce with a fork.

Avoid opening the lid frequently, as each peek releases valuable heat and extends the cooking time.

Carefully Open the Packets

Once finished, carefully open each foil packet away from your face to avoid the hot steam.

The aroma of seasoned steak and buttery potatoes will fill the kitchen.

Serve immediately while everything is piping hot.

Storage Tips

Refrigeration

Allow leftovers to cool completely before transferring them to airtight containers. Refrigerate within 2 hours of cooking and enjoy within 3 to 4 days.

Freezing

Freeze cooled steak and potatoes in freezer-safe containers or freezer bags for up to 3 months. Label each container with the date for easy meal planning.

Reheating

Reheat refrigerated portions in the microwave until they reach an internal temperature of 74°C (165°F). You can also warm them in a covered skillet over medium-low heat with a splash of water or broth to prevent drying out. Thaw frozen portions overnight in the refrigerator before reheating for the best texture.

Variations

Garlic Butter Cajun Steak Packets

Add a few pats of butter and minced garlic before sealing the packets. The butter melts into a rich sauce that coats every bite.

Cheesy Cajun Steak Packets

Sprinkle shredded cheddar or Monterey Jack cheese over the cooked steak and potatoes just before serving. Although this isn’t a traditional cheesy potato side dish, the melted cheese creates an irresistible finish.

Loaded Steak Packets

Top each serving with crispy bacon bits, sour cream, sliced green onions, and shredded cheese for a loaded baked potato-inspired meal.

Mushroom Cajun Steak Packets

Fresh mushrooms absorb the Cajun seasoning beautifully while adding earthy flavor and extra moisture.

Vegetable-Packed Cajun Packets

Add sliced onions, colorful bell peppers, zucchini, or green beans to make the meal even heartier while adding freshness and texture.

Fresh Green Salads

A crisp garden salad with cucumbers, tomatoes, and ranch or vinaigrette provides a refreshing contrast to the bold Cajun flavors.

Broccoli, green beans, asparagus, or Brussels sprouts balance the richness of the steak while adding color to the plate.
