Helpful Tips
- You don’t have to peel the potatoes if you like the skin on. If you don’t peel, wash the potatoes properly and pat them dry.
- Don’t overfill the baking tray. It’s best to have them in a single layer on the tray.
- To add lemon flavor, drizzle some lemon juice on the potatoes after bringing them out of the oven.
Serving Suggestion
Here are some protein suggestions to serve baked onions and potatoes with:
Air fryer chicken quarters
Lemon butter chicken drumsticks

Storing and Reheating
I rarely ever have leftovers of this as it’s so delicious but if you have leftovers or make them ahead, pack them into an airtight container or a Ziploc and put them in the fridge for up to 3 days or store them in the freezer for up to 6 months.
Reheat- Spread them in a baking tray and bake at 180C/360F for 8 minutes or till warmed.
