Pot Roast

Step 1
Preheat the oven to 300 degrees F (150 degrees C).

Step 2
Place roast in a large baking pan; arrange potatoes, onion, carrots, and celery around roast.

Step 3
Pour 3 cups water into the baking pan. Season roast with salt, pepper, and garlic salt. Cover pan with aluminum foil.

Step 4
Bake in the preheated oven until roast is browned and cooked through, about 3 hours.

Step 5
Transfer roast to an oven-safe platter. Remove vegetables using a slotted spoon and arrange them around roast.

Step 6
Reduce oven temperature to 200 degrees F (95 degrees C). Place the platter with roast and vegetables in the oven to keep warm.

Step 7
Pour remaining pan juices into a saucepan; bring to a boil. Stir together remaining 1/2 cup water and cornstarch in a bowl until smooth; pour into boiling pan juices. Reduce heat to medium; cook, stirring constantly, until gravy is thick, about 5 minutes; season with salt and pepper. Stir in browning sauce.
