Step 4: Into The Oven
Place the pan in the oven at 400 degrees for 30 minutes.
Then, drop the heat down to 250 degrees for about 3 hours. (This is where you use the rest of that 12 pack.)
Check on the ribs at 2 1/2 hours. If you can grab a bone and pull it out, it's ready. Once fully cooked, uncover and let rest for 20 minutes.
