Slow-Roasted Au Jus Beef (3 Ingredients) — A Simple Sunday Classic from Grandma’s Kitchen
This oven-baked 3-ingredient au jus roast beef is one of those timeless, no-fuss recipes passed down from my grandmother, and it truly never fails. She used to prepare it on Sundays when she wanted something warm, comforting, and flavorful without spending the whole day in the kitchen.
It’s the kind of meal that fills the house with an incredible aroma while it slowly cooks in the oven, tenderizing into juicy perfection. The best part? It requires almost no effort, just a few simple ingredients and a little patience.
Ingredients
1 beef roast (chuck roast or rump roast works best)
1 packet onion soup mix
1 can or packet of beef consommé (or au jus gravy mix prepared with water)
Instructions
Preheat your oven to 160°C (325°F).
Place the beef roast in a baking dish or Dutch oven.
Sprinkle the onion soup mix evenly over the top.
Pour the beef consommé or prepared au jus mixture around the roast.
Cover tightly with foil or a lid to lock in moisture.
Bake for 3 to 4 hours, until the meat becomes tender and easily pulls apart with a fork.
Let it rest for 10 minutes before slicing.
Serving Suggestion
Serve it with the rich au jus spooned over the top, alongside mashed potatoes, roasted vegetables, or crusty bread to soak up all the savory juices.
A humble recipe, but one that always feels like home—simple ingredients, slow cooking, and unforgettable flavor.
