From the MyKitchenBank Kitchen

A thick, creamy blueberry and lemon shake made with Greek yogurt, chia seeds, and fresh or frozen blueberries. Prepare it the night before—the chia seeds hydrate overnight, creating a pudding-like texture that you blend smooth in the morning. Bright lemon zest and juice cut through the richness, while a touch of honey provides subtle sweetness. Perfect for a grab-and-go breakfast.

Steps

Before you start

Use fresh or frozen blueberries (no thawing needed if frozen)
Have Greek yogurt at room temperature for smoother blending
Zest the lemon before juicing it
Use a tall blender or milkshake-style blender for best results

1
Combine and stir
- In a 16-oz mason jar, combine 5/8 cup (140 g) blueberries, 1/2 cup (115 g) Greek yogurt, 1½ tbsp chia seeds, 6 tablespoons (90 ml) milk, 1 tbsp lemon juice, ¼ tsp lemon zest, ¾ tbsp honey, ⅛ tsp vanilla extract, and a small pinch of salt.
- Stir well with a spoon until the chia seeds are evenly distributed and no large yogurt clumps remain.

Ready when: Chia seeds are scattered throughout and mixture is evenly combined
Tip: Stir thoroughly so the chia seeds don't clump at the bottom—they'll hydrate unevenly if bunched together.
2
Refrigerate overnight
- Cover the jar with a tight-fitting lid and refrigerate for at least 8 hours, or overnight.
- The chia seeds will absorb liquid and swell, creating a thick, pudding-like base.
- Repeat this process in a second 16-oz jar with the remaining ingredients (5/8 cup blueberries, 1/2 cup yogurt, 1½ tbsp chia seeds, 6 tbsp milk, 1 tbsp lemon juice, ¼ tsp lemon zest, ¾ tbsp honey, ⅛ tsp vanilla, and pinch of salt).

Ready when: Mixture is thick, creamy, and spoonable; chia seeds have expanded
Tip: If the mixture seems too thick in the morning, add 1–2 tbsp more milk before blending.
3
Blend until smooth
- Pour the contents of one prepared jar into a blender.
- Add 2–3 ice cubes if you prefer a colder, thicker consistency (optional).
- Blend on high speed for 30–45 seconds until completely smooth and creamy, with no visible seed bits or yogurt streaks.
- The mixture should have a thick milkshake consistency.

Ready when: Shake is smooth, uniform in color, and pours like a thick milkshake with no lumps
Tip: If blending is difficult, let the jar sit at room temperature for 5 minutes first, or add a splash more milk.
4
Pour and serve
- Pour the blended shake into a tall glass.
- Serve immediately.
- Repeat step 3 with the second jar for the second shake, or cover and refrigerate the blended shake in the glass for up to 1 hour.

Tip: For the best texture, drink within 30 minutes of blending. If it sits longer, the shake will separate slightly; stir or re-blend gently to recombine.

Tips

For a thicker shake, increase chia seeds to 4 tbsp and milk to 2/3 cup; for a thinner shake, increase milk to 1 cup.
The overnight hydration mellows the tartness of lemon and creates a silky mouthfeel—don't skip this step.
Frozen blueberries work just as well as fresh and require no prep; they'll keep the shake colder without needing added ice.
If you like extra tang, add ½ tsp lemon juice more per jar, but taste first to avoid overpowering the berry flavor.

Make ahead

Prepare both jars up to 3 days ahead. Store covered in the refrigerator. Blend fresh each morning—takes 1 minute per shake.

Storage & reheating

Prepared overnight jars (before blending): refrigerator up to 3 days. Blended shake: serve immediately or cover and refrigerate up to 1 hour; stir well before drinking as slight separation may occur. Do not freeze—the texture will become grainy.

Substitutions

plain Greek yogurt (full-fat or 2%) → Regular plain yogurt (use ¾ cup + 2 tbsp to account for thinner consistency). Reduces protein slightly but works well; reduce milk to ½ cup to compensate.
chia seeds → Ground flaxseed (use 2 tbsp) or psyllium husk (use 1½ tbsp). Texture will be slightly less gelatinous; flaxseed adds an earthy note.
fresh or frozen blueberries → Blackberries, raspberries, or a mix of frozen berries. Lemon pairing works beautifully with any berry; adjust lemon juice by ½ tbsp if using very tart berries.
raw honey or agave nectar → Maple syrup or coconut sugar (use 1 tbsp + 1 tsp). Maple adds earthiness; coconut sugar is less sweet, so use slightly more.
