Step 1: Prepare the Bananas
Preheat oven to 200°F (93°C) if baking. For a dehydrator, set it to around 135°F (57°C).
Peel and slice the bananas into thin, uniform rounds (about 1/8 inch thick). Keeping them even will help with consistent drying.
Step 2: Toss with Lemon Juice
Coat the banana slices lightly with lemon juice to prevent browning. Add a small amount of coconut oil if you’d like extra crispiness and a hint of coconut flavor.
Step 3: Arrange on the Baking Sheet or Dehydrator Tray
Place slices in a single layer on a parchment-lined baking sheet or on the dehydrator tray. Sprinkle a touch of salt for flavor if desired.
Step 4: Bake or Dehydrate
Oven Method: Bake at 200°F (93°C) for 2-3 hours, flipping halfway through. Cooking time varies with slice thickness, so check until the chips reach desired crispiness.
Dehydrator Method: Dehydrate at 135°F (57°C) for 8-10 hours until fully dried and crispy.
Step 5: Cool and Store
Let chips cool on the tray. They’ll crisp up further as they cool.
Store in an airtight container for up to one week.
