On one plate or shallow bowl, crack egg and beat.
On another, add breadcrumbs, parmesan cheese, salt and pepper and mix well.
Slice eggplant in 1/4-1/2inch slices. Dip in egg, then coat in crumb mixture. Lay in air fryer basket (option to bake or pan fry these as well).
Cook until outer edge is browned and crispy, about 15 minutes, flipping halfway through.
While the eggplant bakes, in skillet, cook sausage.
Add Italian seasoning, sage (if using), crushed red pepper, salt and pepper. Cook until browned.
Add a bit of olive oil and minced garlic. Sautee until garlic is fragrant.
Pour in stock to deglaze the pan. Once pan drippings are picked up, add heavy whipping cream and cook until a slow bubble forms.
Add in both cheeses and stir. Turn heat down and continue to stir until a thick consistency. Adjust seasoning to taste.
When eggplant is done, remove and serve topped with sausage alfredo. Garnish with fresh parsley. Enjoy!
