Tips & Variations
- For extra flavor, sear the beef chunks in a hot pan before placing them in the slow cooker.
- Try using sour cream mashed potatoes for a creamier texture.
- Serve with steamed green beans or a fresh salad to balance the richness.
- If you like more tang, add an extra tablespoon of red wine vinegar.
Storage
Store leftover beef and au jus in an airtight container in the refrigerator for up to 3 days. Mashed potatoes and garlic toast are best stored separately. Reheat the beef gently in a covered pan over low heat to keep it moist. Reheat mashed potatoes in the microwave or on stovetop with a splash of milk, and toast garlic bread again in the oven for crispness.
