In a heated pan, brown ground meat for 8 to 10 minutes and drain excess oil. Retain 1 tablespoon of beef fat.

Season browned ground beef with Italian seasoning, garlic powder, red pepper flakes, salt, and black pepper, and pour coconut aminos. Combine the seasonings well with the ground beef.

Pour diced tomatoes and bring to a gentle simmer for 5 minutes, stirring regularly.

Sprinkle half of parsley and continue stirring for another 60 seconds. Turn off the heat. Set aside.

Cut each zucchini in half, lengthwise. Scoop out the seeds and create a hollow space throughout the core. Retain 1/4 to 1/2 inch flesh from the skin of the zucchini.

Place zucchini halves on the Air Fryer tray. Lightly brush zucchini boats with oil.

In a pre-heated Air Fryer Oven, insert the Air Fryer tray into the cooking chamber. Set at 370F (188C) for 15 minutes. Cook zucchini for 3 to 5 minutes, skin side up. Remove the tray and turn the zucchini, skin side down. Fill all zucchini boats with the meat mixture. Evenly distribute the ground beef mixture among the prepared zucchini. Return the Air Fryer tray with the filled zucchini boats. Cook for 5 minutes.

Sprinkle each zucchini boat with mozzarella cheese on top. Return the tray into the Air Fryer Oven. Melt the mozzarella cheese for 2 to 3 minutes or until bubbly and golden brown to your liking. Remove Air Fryer Tray. Allow the zucchini boats to cool for a few minutes. Transfer the zucchini boats to a plate and garnish with fresh parsley before serving.
