You can also add carrots and potatoes directly into the slow cooker during the last 4–5 hours for a complete one-pot meal.
Tips for Extra Flavor (Optional)
Even though this is a four-ingredient recipe, you can elevate it further if you’d like:
- Sear the roast in a hot skillet for 2–3 minutes per side before placing it in the slow cooker for deeper flavor.
- Add fresh thyme or rosemary for an herbal touch.
- Stir in a splash of Worcestershire sauce for extra savory depth.
But honestly? It’s delicious even without the extras.
