2 cups gluten-free oats Shop
1 tsp cinnamon Shop
0.5 tsp nutmeg Shop
2 cups unsweetened almond milk Shop
0.5 cup chopped apple
0.25 cup chopped walnuts Shop
2 tbsp maple syrup Shop
1 tsp chia seeds Shop

Instructions

1 In a large bowl or individual containers, combine the gluten-free oats, cinnamon, and nutmeg. Stir these dry ingredients together until they are well incorporated and fragrant, ensuring an even distribution of spices.
2 Pour in the unsweetened almond milk and add the chia seeds. Stir everything thoroughly to ensure the chia seeds are not clumped together and the oats are fully submerged in the liquid. This step begins the thickening process.
3 Gently fold in the chopped apple and chopped walnuts. Distribute them evenly throughout the oat mixture, making sure each serving will have a good balance of fruit and nuts. Stir in the maple syrup for sweetness.
4 Cover the bowl or containers tightly with lids or plastic wrap. Refrigerate for at least 8 hours, or preferably overnight, allowing the oats to soften and absorb the liquid, and the flavors to meld beautifully. The mixture will thicken considerably.
5 In the morning, give the overnight oats a good stir. If the mixture is too thick for your liking, you can add a splash more almond milk to reach your desired consistency. Serve chilled, or gently warm them in a saucepan for about 5 minutes for a comforting hot breakfast.

Tips & Notes

Buy oats labeled gluten-free, ideally certified, and check the bag each time. Unlabeled oats often pick up other grains in the field and at the mill. A small number of people with celiac disease also react to oats themselves, so follow your clinician's advice.
Toss the chopped apple in a squeeze of lemon juice before folding it in so it stays pale overnight.
For crunchy walnuts, stir them in the morning rather than the night before. They soften in the almond milk overnight.
