Tender steak bites are cooked in the crockpot in a flavorful au jus that's perfect for serving over mashed potatoes or egg noodles.
Place the cubed steak into a large bowl with the salt and pepper; toss to combine.
Heat a large skillet over medium-high heat and add half of the oil. Sear the steak pieces in batches and place them into the slow cooker. Add more oil to the pan if needed.
Once all the steak has been seared, add the onion and garlic to the slow cooker. Toss with the steak bites.
Pour in the beef stock. Sprinkle with the au jus mix and top with slices of the butter.
Cover the slow cooker and cook on high for 3-4 hours or low 6-8 hours. Stir every 30 minutes or so, if you can. Serve warm, garnished with fresh parsley, if desired.
