Ingredients

2 cups rolled oats
2 ¼ – 2½ cups vanilla or unflavored almond milk (or preferred milk)
1 cup Greek yogurt (plain or vanilla; can substitute with higher protein plant-based yogurt for dairy-free option)
3 tablespoons Instant Jell-O Pistachio Pudding Mix
3 tablespoons chia seeds
2 scoops vanilla or unflavored protein powder (optional)
1 teaspoon honey (or more, to taste after refrigeration)
Toppings: crushed pistachios, whipped cream, sliced bananas or mixed berries, dark chocolate chips (optional)

Instructions

Step 1: Add all the base ingredients—rolled oats, almond milk, Greek yogurt, pistachio pudding mix, chia seeds, protein powder (if using), and honey—into a large airtight container or bowl. Whisk thoroughly until the mixture is smooth and well combined.
Step 2: Cover and refrigerate the mixture for at least 4 hours, or overnight, allowing the oats and chia seeds to absorb the liquid and thicken.
Step 3: After chilling, divide the pudding oats into three bowls or jars for convenient, grab-and-go servings. Add your favorite toppings such as crushed pistachios, banana slices (best added fresh on the day of eating), dark chocolate chips, or whipped cream.
Step 4: Store any leftovers in an airtight container in the refrigerator for up to 5 days.

Tips & Variations

Use plant-based yogurt to make this recipe vegan and dairy-free without sacrificing creaminess or protein.
Adjust honey to your preferred sweetness, especially after the oats have chilled and absorbed the flavors.
Add fresh fruit toppings on the day you serve to keep them vibrant and crunchy.
Try swapping pistachio pudding mix with other instant pudding flavors like vanilla or chocolate for variety.
For extra texture, sprinkle toasted nuts or seeds on top before serving.

Storage

Store leftover overnight oats in a tightly sealed container in the fridge for up to 5 days. When ready to eat, stir well and add fresh toppings. You can enjoy it cold straight from the fridge or let it sit at room temperature for a few minutes if you prefer it less chilled.

How to Serve

Two clear glass cups sit on a wooden board against a white marbled background, each filled with a three-layered chia pudding. The bottom layer is creamy white chia pudding mixed with tiny dark seeds, topped with a layer of chopped green pistachios and dark dried berries. Above that is another thick layer of the pale chia pudding, followed by a top decoration of banana slices, a dollop of white whipped cream, more pistachios and berries, and a light dusting of dark chocolate shavings. Each cup has a silver spoon inserted, standing upright in the pudding. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use other types of milk for this recipe?

Yes, you can use any milk of your choice, including cow’s milk, soy milk, oat milk, or coconut milk. Just keep in mind that thicker or creamier milks will affect the final texture.

Is the protein powder necessary?

No, protein powder is optional. It helps boost the protein content, but the Greek yogurt and chia seeds also provide good protein. Feel free to leave it out or substitute with your favorite protein supplement.
