Trim the stem ends from the green beans. Place the beans in a large bowl.
Drizzle with olive oil and sprinkle with seasoned salt and black pepper. Toss to coat.
Place the beans in the basket of the air fryer. Cook at 200 degrees for 10-12 minutes, shaking the basket halfway through. Beans should be crispy and slightly blistered when finished.
Peel and dice apples. Place apple chunks into a medium bowl, then add cranberries, 1/2 cup of brown sugar, cinnamon, juice from lemon, and mix well.
To make the crumble, use a large mixing bowl and add1/2 cup of brown sugar, salt, flour and cinnamon. Mix the butter cubes and mash to make a consistent clumpy texture.
Pour the apple mix into a baking dish and top with the crumble. Place the dish into the air fryer basket and bake at 180 degrees for 30 minutes.
