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 vigorously to break up any clumps. Cover the bowl 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 juices reduce 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 layer on a parchment-lined baking sheet. Bake for 10 to 12 minutes, stirring once halfway through, until the crumble turns golden brown and crisp. Allow to cool completely on the sheet.
04 - Spoon a layer of chia pudding into the bottom of each serving glass or jar. Add a layer of strawberry compote, followed by a sprinkle 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 texture, or cover and refrigerate until ready to enjoy. Add the oat crumble just before serving if preparing ahead, to preserve its crunch.
