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, chopped chives, paprika, red pepper flakes, salt, and black pepper to create the cowboy butter.
If you prefer, you can sear the steak in a skillet for 2–3 minutes on both sides to lock in the flavors.
Layer the halved baby potatoes at the bottom of the slow cooker. Place the steak on top of the potatoes and then spoon the cowboy butter over everything.
Pour the beef broth around the sides of the slow cooker. Cover the slow cooker and cook on LOW for 6–8 hours or HIGH for 3–4 hours until the steak is tender.
If you want a thicker sauce, stir in a cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) in the last 30 minutes of cooking.
Serve the steak and potatoes on a platter, spoon some sauce over the top, and garnish with fresh parsley for a pop of color.
