Variations & Tips
While the beauty of this recipe is its simplicity, here are a few optional tweaks to make it your own. Note that these additions will change the ingredient count.
For Richer Flavor: Before adding the roast to the slow cooker, sear it in a hot skillet with a bit of oil until deeply browned on all sides. This step builds an extra layer of savory flavor.
For a Thicker, Stew-Like Gravy: At the end of cooking, make a cornstarch slurry (2 tablespoons cornstarch whisked with ¼ cup cold water) and stir it into the hot liquid. Cook on HIGH until the gravy has thickened to your liking.
For a Deeper Onion Taste: Swap one of the yellow onions for a sweet onion, like a Vidalia. It will break down and melt into the gravy, adding a subtle sweetness.
For a Touch of Tang: To balance the richness, stir in 1-2 teaspoons of Worcestershire sauce or a splash of red wine vinegar just before serving.
Leftover Ideas: Leftovers are fantastic. Pile the beef and onions onto toasted bread for an open-faced sandwich, smother it in gravy. You can also shred the beef more finely to use as a filling for baked potatoes or a hearty topping for buttered noodles.
To Reduce Sodium: This is easily done. Be sure to use a reduced-sodium onion soup mix and low-sodium beef broth. You can then adjust the seasoning with salt and pepper at the end to your taste.
