Overnight Muscle Recovery Oats (High-Protein Casein Jar)

A protein-packed jar for next-day muscle repair: rolled oats and slow-release casein whisked into almond milk, layered with Greek yogurt, tart cherries and almond butter, then left to set overnight. By morning it’s a thick, spoonable jar that has been feeding your muscles while you slept.

It’s one of the 20 recipes inside our Muscle Recovery Cookbook, and we’re sharing these Overnight Muscle Recovery Oats in full so you can taste the standard before you buy the book. Ten minutes of hands-on work, no cooking, and two jars at 465 kcal with 28 g of protein each.

Why this recipe works

The trick is casein rather than whey: whisked into almond milk it digests slowly over six to eight hours, drip-feeding amino acids exactly when overnight muscle protein synthesis peaks. Building the jar the night before lets the oats and chia hydrate and thicken in the fridge, while the tart cherries tucked between the layers add anti-inflammatory polyphenols that support recovery.

Ingredients

Oat base

• rolled oats, gluten-free (1 cup)
• casein protein powder, vanilla (2 scoops / 60 g)
• unsweetened almond milk (1.5 cups)
• Greek yogurt, plain 2% (0.5 cup)

Finishing

• tart cherries, pitted (0.5 cup)
• chia seeds (2 tbsp)
• almond butter, natural (2 tbsp)
• ground cinnamon (0.5 tsp)

Optional garnish

• dark chocolate shavings, 85% (1 tbsp)

Instructions

1. Mix the base. In a mixing bowl, whisk casein protein into almond milk until fully dissolved and free of lumps. Casein provides slow-release amino acids overnight.
2. Fold in oats and seeds. Stir in rolled oats, Greek yogurt, chia seeds and cinnamon until evenly combined. The mixture will look loose; it will thicken significantly in the fridge.
3. Layer into jars. Divide between two 500 ml glass jars. Swirl almond butter through the top layer and tuck tart cherries between the oats for pockets of flavour.
4. Chill and serve. Seal the jars and refrigerate at least 6 hours or overnight. Top with dark chocolate shavings and a splash of milk before eating cold.

Chef’s tip

Casein digests slowly over 6–8 hours, making this ideal for recovery during sleep when growth hormone peaks and muscle protein synthesis is highest.
