It seems there might be a typo in your question since "pork toast" is not a common term in cooking. I'll assume you meant "pork roast" instead. The cooking time for an 11 lb. pork roast at 325°F in the oven can vary based on the cut of pork and other factors, but I can give you a general guideline.
For pork roasts, a common rule of thumb is to cook them for about 20 to 25 minutes per pound at 325°F (163°C). So, for an 11 lb. pork roast, you would cook it for approximately 220 to 275 minutes, or 3 hours and 40 minutes to 4 hours and 35 minutes.
However, it's essential to use a meat thermometer to check the internal temperature of the pork roast to ensure it's fully cooked. The USDA recommends cooking pork to an internal temperature of 145°F (63°C) with a three-minute rest time before carving.
Always use a meat thermometer to check the internal temperature in the thickest part of the roast. It's the most reliable way to determine when the pork roast is done and safe to eat. Cooking times can vary depending on your oven, the shape of the roast, and other factors, so relying on the internal temperature is crucial.
