Ingredients

• 3 tablespoons cornstarch
• salt and ground black pepper to taste
• 1 pinch garlic salt, or to taste
• 2 stalks celery, cut into 1-inch pieces
• 2 carrots, cut into 1-inch pieces
• 2 pounds beef pot roast, fat trimmed and discarded

Recipe Instructions

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

Step 3

Bake in the preheated oven until roast is browned and cooked through, about 3 hours. An instant-read thermometer inserted in the thickest part of the roast should read 145 degrees F (65 degrees C). Transfer roast to an oven-safe platter. Remove vegetables using a slotted spoon and arrange them around roast.

Step 4

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

Step 5

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.
