• For extra richness: Stir in a tablespoon of sour cream or butter at the end.

How to Make

1. Prepare the Beef:

2. Layer in the Slow Cooker:
   Place sliced onions and garlic at the bottom. Lay the beef roast on top. Sprinkle the onion soup mix over the roast.

Why It’s Perfect for Slow Cooking

Slow cooking is all about patience — and this dish rewards it. The low, steady heat breaks down the beef’s connective tissue, transforming it into melt-in-your-mouth perfection. The result is a meal that tastes like it’s been simmering in a family kitchen for generations.

Plus, the slow cooker does the heavy lifting — you can go about your day while dinner practically makes itself.

Tips for Success

• Use a well-marbled cut: Fat adds flavor and keeps the beef moist.
• Don’t lift the lid: Each time you do, you lose 20 minutes of cooking time.
• Adjust salt at the end: Onion soup mix and broth can vary in saltiness.
• Thicken to taste: For thicker gravy, add more cornstarch; for thinner, add broth.
• Mash potatoes ahead: Reheat before serving to save time.

Common Mistakes to Avoid

• Overcrowding the slow cooker: The beef needs space to cook evenly.
• Using too lean of a roast: It can dry out — marbling is key.
• Skipping the sear (optional): While not required, browning the beef first adds incredible depth.
• Over-salting early: Always taste after the gravy is done.

How to Store & Reheat

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze beef and gravy (without potatoes) for up to 3 months.
• Reheat: Warm in a saucepan over medium heat with a splash of broth, or microwave in short bursts until hot.
