Ingredients
- 2–3 lb beef chuck roast
- 1 packet onion soup mix
- 1 can (10.5 oz) cream of mushroom soup
Instructions
Preheat your oven to 160°C (325°F).
Place the chuck roast in a baking dish or Dutch oven. Choose a dish that fits the meat snugly to help retain moisture during cooking.
Sprinkle the onion soup mix evenly over the roast, making sure to coat the top well.
Spread the cream of mushroom soup over the roast. Do not dilute it—this thick layer helps lock in moisture and creates a rich gravy as it cooks.
Cover the dish tightly with a lid or aluminum foil. This step is essential to keep the roast tender and prevent it from drying out.
Place in the oven and bake for 3–4 hours. The longer it cooks, the more tender it becomes. You’ll know it’s ready when the meat easily pulls apart with a fork.
Remove from the oven and let it rest for 10–15 minutes before serving. This helps the juices redistribute throughout the meat.
Serving Suggestions
Serve this pot roast with mashed potatoes, rice, or egg noodles to soak up the rich gravy. Add a side of roasted vegetables or a simple salad for a complete meal.
