Cut about an inch off the tops of the artichokes and cut off the stems to make a flat bottom. Use kitchen shears to trim the sharp tips off the leaves.
Bring a large pot of salt water to a boil. Add the artichokes and place a heat-safe dish on top of them to keep them submerged in the water. Boil for 15 minutes. Remove and set aside upside down to drain and cool.
Meanwhile, preheat the oven to 375 degrees F (190 degrees C).
In a large bowl, mix together the Italian sausage, minced garlic, Italian seasoning and 1/2 cup (50 grams) grated parmesan, until just combined. Do not over-mix.
Once the artichokes are cool enough to handle, dry them with paper towels, gently pry open the center leaves, and use a spoon with a twisting motion to scoop out the fuzzy choke inside. Place the artichokes into a stoneware baking dish, facing up.
Drizzle the artichokes all over with lemon juice and olive oil, including the tops and sides.
Stuff each artichoke with the sausage mixture, making sure you get some between all the leaves and in the center. Sprinkle the artichokes with the remaining 2 tablespoons (30 grams) grated parmesan.
Cover the baking dish with foil. Bake for 40-50 minutes, until the sausage is cooked through (to an internal temperature of 165 degrees F (74 degrees C)) and the outer leaves are easy to remove.
Remove the foil. Set the oven to broil and place the stuffed artichokes under the broiler for a couple of minutes to brown the cheese.
