Why is my roast chewy?

Chef's answer
If it's not cooked correctly, that same cut of meat can be distressingly tough, chewy or dry. A failed pot roast can result from undercooking, overcooking or choosing the wrong cut of meat, so before you can fix it you'll need to decide where you've gone wrong.

For perfectly crisp strips with tender-but-not-gummy fat, start the bacon in a cold pan over medium-low heat, and take your time. Going low and slow ensures the fat will render out properly, and provides the bacon its own grease to cook and crisp in.16 Jan 2019
