01 - In a mixing bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until fully combined. Let the mixture rest for 5 minutes, then whisk again to break up any clumps. Cover tightly and refrigerate for at least 2 hours or overnight until the pudding reaches a thick, creamy consistency.
02 - Combine the sliced strawberries, lemon juice, and maple syrup in a small saucepan set over medium heat. Cook for 6 to 8 minutes, stirring occasionally, until the strawberries break down and the liquid reduces into a glossy, syrupy sauce. Remove from heat and let cool completely.
03 - Preheat the oven to 350°F. In a bowl, toss together the rolled oats, chopped nuts, melted coconut oil, maple syrup, ground cinnamon, and salt until evenly coated. Spread the mixture in a thin, even layer on a parchment-lined baking sheet. Bake for 10 to 12 minutes, stirring once halfway through, until the crumble is golden brown and crisp. Allow to cool completely on the pan.
04 - Spoon a layer of chia pudding into the bottom of each glass or jar. Add a generous spoonful of strawberry compote, followed by a sprinkling of oat crumble. Repeat the layers once more for a taller parfait, if desired. Finish with a few slices of fresh strawberry on top.
05 - Serve the parfaits immediately for the best crunch, or cover and refrigerate for up to several hours before serving. If preparing ahead, store the oat crumble separately and add it just before serving to preserve its crisp texture.
