Ingredients

Main Ingredients

• 2 pounds (900g) sirloin steak, cut into 1½-inch cubes
• 1½ pounds (680g) baby Yukon Gold potatoes, halved
• 6 tablespoons unsalted butter, melted
• 6 cloves garlic, minced
• 2 tablespoons olive oil
• 1 teaspoon onion powder
• 1 teaspoon smoked paprika
• 1 teaspoon Italian seasoning
• 1 teaspoon dried thyme
• 1 teaspoon kosher salt
• ½ teaspoon freshly ground black pepper
• ½ teaspoon crushed red pepper flakes (optional)

Optional Add-Ins

• 1 cup sliced mushrooms
• 1 medium onion, sliced
• 1 cup green beans (add during the last 45 minutes)
• 1 tablespoon Worcestershire sauce
• ¼ cup grated Parmesan cheese

Garnish

• Fresh chopped parsley
• Extra melted butter
• Freshly grated Parmesan cheese

Equipment Needed

• 6- to 7-quart slow cooker
• Large mixing bowl
• Measuring cups and spoons
• Cutting board
• Sharp knife
• Skillet (optional, for searing)
• Serving spoon

Step 1: Prepare the Ingredients

Wash and halve the baby potatoes.

Trim any excess fat from the steak and cut it into evenly sized cubes.

Pat the steak dry with paper towels to help it brown if you choose to sear it.

Step 2: Make the Garlic Butter

In a small bowl, whisk together:

• Melted butter
• Olive oil
• Minced garlic
• Onion powder
• Smoked paprika
• Italian seasoning
• Thyme
• Salt
• Black pepper
• Worcestershire sauce (if using)

Step 3: Optional Sear

For extra flavor, heat a large skillet over medium-high heat.

Add a small amount of oil and sear the steak cubes for 1–2 minutes per side until lightly browned.

The steak does not need to be fully cooked.

This step is optional but adds a deeper, richer flavor.

Step 4: Assemble the Slow Cooker

Place the halved potatoes in the bottom of the slow cooker.

Add the steak cubes over the potatoes.

If using mushrooms or onions, add them now.

Pour the garlic butter mixture evenly over everything.

Gently toss to coat.

Step 5: Slow Cook

Cover and cook:

• LOW: 6–7 hours
• HIGH: 4–5 hours

The potatoes should be fork-tender, and the steak should be cooked through and tender.

If adding green beans, stir them in during the final 45 minutes of cooking.

Food Safety Note: For food safety, steak should reach a minimum internal temperature of 145°F (63°C). Because slow cookers continue cooking over several hours, the steak will typically exceed this temperature and become very tender.

Step 6: Finish the Dish

Gently stir everything together.

Taste and adjust seasoning if needed.

Sprinkle with Parmesan cheese and chopped fresh parsley.

Drizzle with a little extra melted garlic butter before serving for even more flavor.

Serving Suggestions

Serve this hearty meal with:

• Steamed broccoli
• Roasted asparagus
• Garlic bread
• Caesar salad
• Green beans
• Buttered corn
• Dinner rolls
• Coleslaw

Expert Tips

Choose the Right Cut

Sirloin offers a great balance of tenderness and flavor. Chuck steak can also be used and becomes especially tender after slow cooking.

Cut Ingredients Evenly

Uniform steak cubes and similarly sized potato halves help everything cook evenly.

Don’t Overfill the Slow Cooker

Leave enough room for heat to circulate properly.

Add Delicate Vegetables Later

Green beans, peas, or spinach should be added near the end of cooking so they stay vibrant and don’t become mushy.

Fresh Garlic Makes a Difference

Freshly minced garlic gives the butter sauce a much richer flavor than garlic powder alone.

Delicious Variations

Cheesy Garlic Butter Steak

Stir in 1 cup shredded mozzarella or cheddar cheese during the last 10 minutes of cooking.

Cajun Steak and Potatoes

Replace the Italian seasoning with Cajun seasoning for a spicy Southern twist.

Mushroom Garlic Butter

Double the mushrooms and finish with a splash of heavy cream for a richer sauce.

Herb Butter Steak

Add fresh rosemary and thyme during the last 30 minutes of cooking for a fragrant finish.

Bacon Ranch Version

Mix in cooked, crumbled bacon and a teaspoon of dry ranch seasoning before serving.

Creamy Garlic Steak

Stir in ½ cup heavy cream and 2 ounces cream cheese during the final 20 minutes for a velvety sauce.

Make-Ahead Instructions

Prepare the steak, potatoes, and garlic butter mixture the night before.

Store them separately in the refrigerator.

In the morning, combine everything in the slow cooker and start cooking.

Storage

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze for up to 2 months. Note that potatoes may become slightly softer after thawing.

Reheating

Microwave

Heat individual portions for 2–3 minutes, stirring halfway through.

Stovetop

Warm gently in a skillet over medium-low heat, adding a splash of beef broth or a little melted butter if needed.

Oven

Cover with foil and bake at 325°F (163°C) for 15–20 minutes, or until heated through.

Frequently Asked Questions

Can I use a different cut of beef?

Yes. Sirloin, chuck roast, stew meat, or New York strip all work well. Tougher cuts like chuck become especially tender after slow cooking.

Do I need to peel the potatoes?

No. Baby Yukon Gold or red potatoes have thin, tender skins that add texture and nutrients.

Can I add vegetables?

Absolutely. Mushrooms, onions, carrots, bell peppers, or green beans are excellent additions. Add firmer vegetables at the beginning and delicate ones near the end.

Why is my steak dry?

Overcooking lean cuts on the High setting can make them less juicy. Cooking on Low and choosing a well-marbled cut often produces the most tender results.

Can I make this dairy-free?

Yes. Substitute the butter with a dairy-free butter alternative or use extra olive oil, though the flavor will be slightly different.
