Step-by-Step Instructions for Slow Cooker Creamy Garlic Butter Steak and Potatoes
Step 1: Prepare the Slow Cooker and Potatoes
Lightly grease the inside of a 6-quart slow cooker with nonstick cooking spray. Rinse the baby Yukon Gold potatoes under cool running water until clean. Cut larger potatoes in half to ensure even cooking and leave smaller ones whole if roughly 1 inch in diameter. Place the prepared potatoes at the bottom of the slow cooker to create a base for your delicious Slow Cooker Creamy Garlic Butter Steak and Potatoes.
Step 2: Cut and Season the Steak
On a clean cutting board, trim any excess fat from the 2 pounds of beef sirloin steak, then cut it into 1½-inch cubes. Pat the steak cubes dry using paper towels and transfer them to a large mixing bowl. Season the steak with salt, freshly ground black pepper, smoked paprika, and garlic powder, tossing gently until every cube is evenly coated with the flavorful mixture.
Step 3: Sear the Steak
Heat 1 tablespoon of olive oil and 2 tablespoons of unsalted butter in a large heavy skillet over medium-high heat. Once the butter is foaming, add small batches of the seasoned steak cubes, searing them for 1 to 2 minutes on each side until they form a golden brown crust. Avoid overcrowding the skillet to ensure proper browning, then transfer the browned steak cubes to the slow cooker, arranging them over the potatoes.
Step 4: Sauté the Onion and Garlic
Peel and finely dice the medium yellow onion, and mince the 6 cloves of garlic. Lower the skillet's heat to medium and add 2 more tablespoons of butter. Once melted, toss in the diced onion, cooking for about 3 to 4 minutes until softened and translucent. Stir in the minced garlic and sauté for an additional 30 seconds until fragrant, filling your kitchen with comforting aromas.
Step 5: Create the Garlic Butter Broth
Pour 1 cup of low sodium beef broth into the skillet, using a wooden spoon to scrape up any browned bits from the bottom for added flavor. Add the Worcestershire sauce, Dijon mustard, Italian seasoning, dried thyme, dried rosemary, and optional crushed red pepper flakes. Whisk the mixture until well combined, creating a delicious garlic butter broth to pour over the steak and potatoes.
Step 6: Combine Ingredients and Cook
Pour the flavorful garlic butter broth evenly over the steak and potatoes in the slow cooker. Dot the remaining 2 tablespoons of unsalted butter over the top. Securely cover the slow cooker with its lid, set it to LOW, and let it cook for approximately 5 hours. Avoid lifting the lid frequently to maintain a consistent cooking temperature for perfectly tender meat and fork-tender potatoes.
Step 7: Check for Doneness
After 5 hours, check the potatoes for tenderness with a fork, and do the same for the steak. Both should be cooked through and tender. If necessary, continue cooking until the potatoes reach the desired tenderness. This slow cooking method ensures each bite of your Slow Cooker Creamy Garlic Butter Steak and Potatoes melts in your mouth.
Step 8: Prepare the Creamy Sauce
In a medium mixing bowl, place the softened cream cheese cubes and pour in 1 cup of heavy whipping cream. Whisk together until mostly smooth. To prevent curdling, gradually add a small amount of hot cooking broth from the slow cooker while whisking gently. This will create a luscious, creamy sauce that perfectly coats the beef and potatoes.
Step 9: Thicken the Sauce
In a small bowl, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water to create a slurry. Slowly stir the slurry into the creamy sauce in the mixing bowl, ensuring an even consistency. If the sauce becomes too thick, add a splash of beef broth or milk for desired creaminess, then pour this velvety mixture over the steak and potatoes in the slow cooker.
Step 10: Serve and Garnish
After combining everything, ladle your Slow Cooker Creamy Garlic Butter Steak and Potatoes into bowls. Finish with a sprinkle of freshly chopped parsley for a vibrant touch. This hearty dish is now ready to bring warmth and comfort to your dinner table, making it a delightful meal for family and friends.
