How to Make Slow Cooker Cowboy Butter Steak & Potatoes

Ingredients:

2 lbs chuck roast or sirloin tips
1.5 lbs baby potatoes (Yukon gold or red), halved
1/2 cup unsalted butter, softened
4 garlic cloves, minced
2 tbsp Dijon mustard
2 tbsp lemon juice
2 tbsp fresh parsley, chopped
1 tbsp fresh chives, chopped
1 tsp paprika
1/2 tsp red pepper flakes
1 tsp salt
1/2 tsp black pepper
1/4 cup beef broth

Directions:

In a bowl, mix the softened butter, minced garlic, Dijon mustard, lemon juice, chopped parsley, chives, paprika, red pepper flakes, salt, and black pepper to form the cowboy butter.
If you want, sear the steak in a skillet for 2–3 minutes on both sides to lock in the flavor.
Place the halved potatoes at the bottom of the slow cooker.
Put the steak on top of the potatoes and spoon the cowboy butter over the entire dish.
Pour the beef broth around the sides of the slow cooker to add moisture.
Cover the slow cooker and cook on LOW for 6–8 hours or on HIGH for 3–4 hours until the steak is nice and tender.
If you want a thicker sauce, stir in a cornstarch slurry (1 tbsp cornstarch mixed with 1 tbsp water) during the last 30 minutes of cooking.
Serve the steak and potatoes on a platter, spoon the sauce on top, and garnish with fresh parsley.

Make sure to check the meat for doneness as cooking times may vary depending on the thickness of the steak.
