Tips & Variations
- For deeper onion flavor, caramelize the onions in a skillet before adding them to the slow cooker.
- Substitute red wine for some of the beef broth for a richer sauce.
- Use dried thyme if fresh is not available, but reduce the quantity to 1/4 teaspoon to avoid overpowering the dish.
- To thicken the gravy without flour, reduce the sauce by simmering it on the stove for 10-15 minutes.
Storage
Store leftover pot roast and gravy in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of beef broth if the sauce has thickened too much.
