1. Submerge 6 empty half-pint jars on a rack in a large pot of water. Cover and bring to a rolling boil, then reduce heat to low to keep jars warm until ready to fill.
2. Tumble blueberries and lemon zest and juice into a wide, nonreactive 8-quart pot. Whisk together sugar and pectin in a small bowl, then stir into pot until combined.
3. Bring to a vigorous boil over high heat. Reduce heat to medium-high; cook, stirring frequently and adjusting heat as needed to maintain a gentle boil, until volume has reduced by at least 1/3, 20 to 25 minutes. Stir in thyme after 18 minutes of cooking. Remove pot from heat and check for set.
4. Working with one jar at a time, remove empty jars from canning pot. Using a wide-mouth funnel, carefully ladle jam into jars, leaving 1/2 inch for headspace. Use a clean wooden chopstick to work air bubbles out of jars. Check headspace again and add more jam if necessary to bring to 1/2 inch from the top.
