Recipe Ingredients

  • 1/2 cup Greek Yogurt: Creamy and luscious, it introduces a tangy contrast, adding depth and creaminess to the mix.
  • 1/2 cup Almond Milk: A gentle, nutty liquid that binds the oats and yogurt, lending a smooth and silky texture that makes every spoonful a delight.
  • 1 tablespoon Chia Seeds: Tiny yet mighty, these seeds swell up, offering little bursts of texture and a powerhouse of nutrients.
  • 1 tablespoon Honey: Nature’s nectar, it drizzles sweetness throughout, balancing the tang of the yogurt and the earthiness of the oats.
  • 1/2 cup Fresh Berries (choose from strawberries, blueberries, or raspberries): These are the jewels in the crown, bursting with freshness, their vibrant colors and flavors dancing on the palate.
  • 2 tablespoons Sliced Almonds: Adding a delightful crunch, their nutty flavor complements the berries and oats, rounding off each bite.
  • 1/2 teaspoon Vanilla Extract: A whisper of vanilla weaves through the oats, a subtle hint that elevates the entire concoction, infusing it with warmth and aroma.

How to Make This Mason Jar Overnight Oats Recipe

  • Gather Your Ingredients: Begin by assembling all your ingredients. This act of preparation not only simplifies the process but also infuses a sense of calm and readiness into your culinary adventure.
  • Choose Your Jar: Select a Mason jar or any similar glass jar with a lid. The size should be large enough to accommodate the expansion of the oats and the layers of your ingredients, typically around 16 ounces.
  • Layering the Base: Pour 1/2 cup of old-fashioned rolled oats into your jar. These oats will swell overnight, creating a creamy and tender base for your breakfast.
  • Adding Liquids: To the oats, add 1/2 cup of almond milk and 1/2 cup of Greek yogurt. The almond milk brings a light nuttiness, while the Greek yogurt adds a creamy depth.
  • Sweetness and Flavor: Stir in 1 tablespoon of honey for a natural sweetness and 1/2 teaspoon of vanilla extract for a hint of aromatic flavor.
  • The Nutrient Boost: Sprinkle 1 tablespoon of chia seeds into the mix. These seeds will not only thicken your oats but also add a punch of omega-3 fatty acids, fiber, and protein.
  • Adding Freshness: Top your oat mixture with 1/2 cup of fresh berries. Whether you choose strawberries, blueberries, or raspberries, these will add a refreshing burst of flavor and a splash of color.
  • Nutty Crunch: Finish off with 2 tablespoons of sliced almonds for a satisfying crunch that contrasts beautifully with the creamy oats.
  • Seal and Settle: Once your jar is filled, seal it with the lid. Give it a gentle shake to mix the ingredients slightly, then place it in the refrigerator overnight.

Serving Instructions

  • Wake and Shake: In the morning, give your Mason jar a good shake to mix all the layers and flavors. You can also stir it with a spoon if you prefer a more gentle mixing.
  • Garnish (Optional): For an extra touch of freshness, garnish with additional fresh berries and a sprinkle of sliced almonds right before serving.
  • Enjoy Cold: This recipe is designed to be enjoyed cold, straight from the fridge. It offers a refreshing start to your day, especially in the warmer months.

Storage and Freezing Instructions


  • Your Mason Jar Overnight Oats can be stored in the refrigerator for up to 5 days. Always ensure the lid is tightly sealed to maintain freshness and prevent the oats from drying out.
  • It’s perfect for meal prep, allowing you to assemble several jars at the beginning of the week for a quick and healthy breakfast option every day.


  • While freezing is not recommended for this recipe due to texture changes (the yogurt and fresh berries may not thaw well), you can freeze the oat mixture without the yogurt and berries if necessary.
  • If you choose to freeze, place your oat mixture in a freezer-safe jar, leaving some space for expansion. It can be stored for up to 1 month.
  • Thaw overnight in the refrigerator and add yogurt and fresh berries in the morning before serving.
