Introduction

Start your day with a refreshing twist on overnight oats—this Zesty Key Lime Pie version is bright, creamy, and perfectly balanced. It’s an easy, no-cook breakfast that delivers a burst of citrusy flavor and satisfying texture.

A clear glass filled with a creamy, white mixture speckled with tiny seeds and swirls of bright green zest throughout the layers. The top layer is covered with a generous mound of light brown oats, adding a rough texture, and two fresh lime slices rest upright on top, showing their bright green and juicy interiors. Around the glass, whole and halved limes are placed on a white marbled surface, with some loose oats scattered nearby, creating a fresh and natural feel.

Ingredients

1 cup Old Fashioned Oats (rolled oats are a good substitute, avoid instant oats)
2 tablespoons Chia Seeds (ground flaxseeds can be a suitable alternative)
1 cup Milk (use your favorite dairy or non-dairy milk)
½ cup Key Lime Greek Yogurt (regular Greek yogurt can be used with more lime juice)
2 tablespoons Honey (maple syrup is a great vegan substitute)
¼ cup Key Lime Juice (regular lime juice can be used if key limes aren’t available)
¼ cup Crushed Graham Crackers (substitute with crushed cookies or granola if desired)

Instructions

Step 1: In a jar or bowl, combine the oats and chia seeds evenly.
Step 2: Stir in the milk, key lime Greek yogurt, honey, and key lime juice until well combined.
Step 3: Cover the mixture and refrigerate for at least 5 hours or overnight to allow the oats to soften and flavors to meld.
Step 4: Before serving, give the oats a good stir and top with the crushed graham crackers for a delightful crunch.

Tips & Variations

For a vegan version, substitute honey with maple syrup and use a plant-based yogurt and milk.
If you prefer a smoother texture, soak the chia seeds in the milk for 10 minutes before mixing with oats.
Add a handful of fresh berries or zest some lime peel on top for extra freshness and color.
Use regular lime juice if key lime juice is unavailable—it still delivers great flavor.

Storage

Store the prepared overnight oats covered in the refrigerator for up to 3 days. Stir well before eating and add crushed graham crackers just before serving to maintain their crunch. Enjoy chilled or let the oats sit at room temperature for 10 minutes if you prefer a less cold breakfast.

How to Serve

A clear glass jar filled with a creamy, thick mixture that has small, dark chia seeds evenly spread throughout. On top, there is a layer of crumbled beige graham cracker pieces and tiny green lime zest scattered lightly, adding texture and color contrast. Two larger graham cracker squares stand upright at the back edge of the jar, giving height to the presentation. The jar sits on a white marbled surface with green limes blurred in the background, creating a fresh and vibrant feel. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use quick oats instead of old fashioned oats?

It’s best to use old fashioned or rolled oats for the right texture. Quick oats may become too mushy after soaking overnight.

What if I don’t have key lime yogurt?

You can substitute regular Greek yogurt and increase the lime juice slightly to bring out more tangy flavor. Adding a bit of lime zest can also help mimic the key lime taste.
