In a large bowl or on a baking sheet, sprinkle the zucchini on all sides with the salt. Toss so it is completely coated. Let this sit while you prepare the sauce. Preheat the oven to 400 degrees.
1.5 pounds zucchini (about 3-4 zucchini), quartered & halved crosswise, 1 1/2 teaspoons Morton kosher salt*
In a large skillet, over medium heat, sauté the sausage until it is brown and cooked through. Be sure to use your spoon to break it up into small bits as it cooks.
1 pound ground Italian sausage, mild or hot
Using a slotted spoon, transfer the sausage to a 9 x 13 baking dish, allowing the excess grease to drain into the skillet. Save the grease and the skillet for Step 6.
Add the jar of sauce and the Italian seasoning to the baking dish. Stir to combine with the sausage.
24-ounce jar pasta sauce*, 1 teaspoon Italian seasoning
Using paper towels, pat the zucchini completely dry.
Heat the skillet of grease over medium heat. There should be about 2 Tablespoons or so left from the meat. Add a neutral oil if needed. Place about half of the zucchini in the skillet and allow them to fry on each side for a few minutes or until brown.
Remove the zucchini from the skillet, allowing excess oil to drip off each piece. Place directly into the baking dish with the meat sauce. Repeat this process with the remaining zucchini. Nestle them into the sauce.
In a medium mixing bowl, combine the panko, butter, and garlic. Set aside.
1/2 cup panko bread crumbs, 2 Tablespoons salted butter, melted, 1/2 teaspoon granulated garlic
Arrange the mozzarella slices on top of the zucchini evenly across the baking dish. Sprinkle the panko mixture on top of the mozzarella.
12 ounces fresh mozzarella, sliced
Bake for 12-15 minutes. Broil for a couple of minutes, watching closely, to brown the top if desired.
