Why You’ll Love These Lemon Raspberry Overnight Oats

• High protein from Fairlife milk, Greek yogurt, and protein powder

• Fiber‑rich oats and chia seeds to keep you full and satisfied

• Bright lemon flavor with juicy raspberries

• Easy to prep once and enjoy all week

• THM‑friendly when using on‑plan ingredients

They’re perfect for spring and summer, but honestly delicious any time of year.

Ingredients for Lemon Raspberry Overnight Oats (4 servings)

• 1 1/2 cups milk (I use a mix of Fairlife and unsweetened almond milk)

• 1 cup old‑fashioned oats

• 1 cup non‑fat Greek yogurt

• 3 tablespoons chia seeds

• 1 teaspoon vanilla

• 1–2 tablespoons lemon juice (to taste)

• 1–2 teaspoons lemon zest (to taste)

• 2–3 scoops vanilla protein powder

• Sweetener of choice, to taste (optional)

• 12 oz fresh raspberries (I only used 6 oz the first time and really felt it needed more raspberries)

You can adjust the amount of lemon juice and zest depending on how tart you like your oats, and you can even use lemon extract in place of—or in addition to—the lemon juice.

How to Make Lemon Raspberry Overnight Oats

Step 1: Blend the base

In a blender, combine the milk, oats, non‑fat Greek yogurt, chia seeds, vanilla, lemon juice, and lemon zest. Blend until everything is well combined and slightly thick.

Step 2: Add protein powder

Add 2–3 scoops of vanilla protein powder to the blender and blend again until smooth. This turns the oats into a creamy, high‑protein mixture.

Step 3: Taste and sweeten

Taste the mixture. If you want it sweeter, add your favorite on‑plan sweetener and blend or stir again. If you want it more tart, you can add a little more lemon juice or zest.

Step 4: Prep the raspberries and containers

Divide your fresh raspberries among four containers or jars. You can:

• Layer raspberries at the bottom and top

• Stir them into the oat mixture

• Create pretty layers with oats and berries alternating

Using the full 12 oz of raspberries gives a bright, fruity flavor in every bite.

Step 5: Pour and chill

Evenly pour the blended oat mixture into the four containers over the raspberries. Cover and refrigerate for at least 4 hours, or overnight for the best texture.

In the morning, your lemon raspberry overnight oats will be thick, creamy, and ready to grab and go.

How to Serve and Customize

• Top with extra fresh raspberries or lemon zest for a pretty finish

• Add a sprinkle of unsweetened coconut or sliced almonds for crunch

• Add a little extra Fairlife or almond milk if you prefer a looser texture

• Swap raspberries for mixed berries or blueberries if that’s what you have

These oats are delicious straight from the fridge, but you can let them sit at room temperature for a few minutes if you prefer them slightly less cold.

Tips for the Best Lemon Raspberry Overnight Oats

• Use old‑fashioned oats (not quick oats) for the best texture

• Adjust lemon juice and zest to match your tartness preference

• If using lemon extract, start with a small amount and add more as needed

• Shake or stir before eating if the oats have thickened a lot overnight

Making this recipe your own is as simple as tweaking the lemon and raspberry levels until it’s just right for you.

FAQ: Lemon Raspberry Overnight Oats

Can I use only one type of milk?
Yes, you can use all Fairlife or all unsweetened almond milk if you prefer. The texture may be slightly different, but it will still work well.

Can I make this dairy free?
To make it dairy free, use a dairy‑free yogurt, a dairy‑free milk, and a plant‑based protein powder. The flavor will change slightly, but the recipe still works.

How long do these overnight oats last in the fridge?
These lemon raspberry overnight oats keep well for about 3–4 days in the refrigerator. The raspberries may soften over time, but the flavor is still delicious.

Can I use frozen raspberries?
Yes, you can use frozen raspberries. Add them straight to the jars; they’ll thaw and release their juices into the oats as they sit.
