Chef’s Tips for Foolproof Slow Cooking

For the best results, follow these pro tips:

• Use Prime Cuts: Opt for hand-cut prime top sirloin for the best texture and flavor. Avoid pre-packaged cuts, which can be tougher.
• Don’t Overcrowd the Crockpot: Ensure the ingredients are spread out evenly to allow even cooking and proper sauce distribution.
• Let It Cook Slowly: Cooking on LOW for 8 hours ensures the beef stays tender without falling apart. If using HIGH, reduce the time to 4 hours.
• Stir Occasionally: While the Crockpot does most of the work, give it a gentle stir halfway through to ensure even flavor distribution.

Ingredients

• 2 pounds raw hand-cut prime top sirloin steak tips
• 1 (10.5-ounce) can condensed cream of mushroom soup
• 1 cup diced white onions
• 2 sticks (8 ounces) golden garlic-herb cowboy butter
• 1/2 cup savory au jus mix

Step-by-Step Instructions

What to Serve With It & Storage Tips

This hearty dish pairs perfectly with creamy whipped mashed potatoes or a side of crusty bread to soak up the rich au jus. For a lighter option, serve it over egg noodles or rice. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply place the mixture in a microwave-safe dish and warm on high for 2–3 minutes, stirring occasionally. For longer storage, freeze the leftovers in portions for up to 3 months.
