Recipe Details

Prep time: 10 minutes | Cook time: 0 minutes | Total time: 8 hours 10 minutes | Yield: 1 serving | Category: Breakfast | Cuisine: American

Ingredients

• 1/2 cup old-fashioned rolled oats
• 1 tablespoon chia seeds
• 3/4 cup unsweetened soy milk (see substitutions)
• 1/2 cup fresh or frozen blueberries, divided
• 1 teaspoon finely grated lemon zest (from 1 small lemon)
• 1 teaspoon maple syrup, optional

Instructions

1. Combine the oats, chia seeds, soy milk, and lemon zest in a 12–16 oz jar or bowl.
2. Gently mash half of the blueberries with a fork, and stir them into the oat mixture so the color disperses.
3. Cover and refrigerate at least 6–8 hours, or overnight, until thickened.
4. Before serving, stir once; then top with the remaining blueberries and a drizzle of maple syrup, if using.

Why This Breakfast Works

This recipe pairs whole grains with seeds and fruit for a balanced texture. Because it uses plant-based milk and chia, it keeps saturated fat low. Additionally, lemon zest brightens flavor without added sugar. The make-ahead format saves morning time, and you can easily scale the recipe for more servings.

Variations & Substitutions

• Milk swap: Use unsweetened oat or almond milk instead of soy milk for a milder flavor.
• Boost protein: Stir in 2 tablespoons plain plant-based yogurt or 2 tablespoons powdered plant protein before refrigerating.
• Fruit: Substitute raspberries or sliced strawberries for blueberries, or use a 1/2 cup mixed berries.
• Sweetener: Replace maple syrup with 1 teaspoon honey if not strict vegan.

Storage & Make-Ahead

Refrigerate in a sealed jar for up to 4 days. Meanwhile, add fresh fruit just before serving to preserve texture. Freezing is not recommended as the texture changes after thawing.

Nutrition & Heart-Health

Nutrition values are estimates. This recipe provides fiber from oats and chia, plant-based protein from soy milk and chia, and vitamin C from lemon and blueberries. Heart-health rating: 2 of 5 hearts because it contains a plant milk (soy milk). For a plant-forward swap, use unsweetened oat or almond milk; alternatively, blend 1/4 cup silken tofu with 1/2 cup water to create a creamy, higher-protein base.
