Preheat oven to 180C/350F/Gas 4 and grease an 8” x 8” baking dish. Set aside.
Place apples in a large non-reactive bowl and toss with fresh lemon juice.
Add maple syrup, apple juice, cinnamon, allspice, thyme leaves, and salt.
Toss to combine and set aside.
Combine topping ingredients in a separate bowl and stir until oats are thoroughly coated and all ingredients are well combined. Set aside.
Pour the apple mixture into the prepared baking dish and spread it into an even layer.
Spread the topping evenly across the top in a uniform layer, as well.
Place into the preheated oven and bake for 30 minutes. If the top layer is nicely browned, cover the dish loosely with aluminum foil to prevent over-browning. Continue baking for another 15-20 minutes or until the apple crisp is nice and bubbling. Remove from oven and set aside to cool for 5-10 minutes.
Serve warm with some vanilla bean iced cream or freshly whipped cream, if desired. Enjoy!
