Step 2: How to make homemade beef stock. Beef stock recipe. Started by roasting the frozen bones… at 425° F for approx 1 hour …. Added roasted bones and frozen vegetable scraps to a stock pot and covered with water. Brought to a boil and then simmered for approximately 4 1/2 hours. Smells delicious.Taste tested, needed salt and pepper. It’s cooling now. Then I’ll strain it, put into bags and containers, and into the freezer for later use.I forgot to take a picture of the roasted bones in the pan
