Prep. Prepare the air fryer basket by lining it with foil. Remove the foil before starting the air fryer preheat. This will prevent the foil from being moved while the pre-heat is in process.
Beets. Using a vegetable peeler, peel the beets. Cut each in half and cut off the top and ends, discard. Cut the beets into 3/4" x 3/4" cubed pieces. Drizzle with 2 teaspoons olive oil. Toss to coat and sprinkle with sea salt.
2 large beets (3 1/2 cups when cubed), 2 teaspoons olive oil (2 for beets, 2 for apples), 1/8 teaspoon sea salt
Apples. Cut apples into 3/4" x 3/4" cubed pieces. Add apples to a bowl. Drizzle with remaining 2 teaspoon olive oil and toss to coat. Add the walnuts to the bowl, don't coat. Set aside.
1 large sweet apple (2 cups when cubed), Fuji, Honeycrisp, Pink Lady, Jazz, etc.
Air Fry. (Beets) Start the air fryer, 400 degrees for 25 minutes. After the preheat is complete, remove the basket (stop the timer if needed). Carefully place the foil liner back in the air fryer basket and add the beets.
More Cooking. Return the air fryer basket to the fryer and resume cooking.
Apples & Walnuts. Where there are 10 minutes remaining in the cooking, remove the air fryer basket (pause the timer if needed). Add in the apples and walnuts. Be sure to spread everything out into one layer in the basket.
