Overnight Oats with Hemp and Matcha (450 Cal, 45g Protein)

Overnight oats have been a meal prep staple long enough to stop being a trend, which is why every version on social media now adds 40 ingredients and calls it a lifestyle. This one is 8 ingredients assembled in 3 minutes the night before. The protein powder is non-negotiable — oats alone give you 5g protein per half cup, which is not enough to anchor a meal. The matcha provides L-theanine and EGCG without adding calories worth tracking. Hemp seeds add omega-3 ALA, magnesium, and a few extra grams of complete protein. Blueberries are the fisetin source — the same senolytic compound that appears in the yogurt bowl.

45g protein. No cooking. No morning prep. Ready when you open the fridge.

Ingredients

• 1/2 cup rolled oats (not instant)
• 1/2 cup Chobani plain nonfat Greek yogurt
• 1 scoop vanilla protein powder (25g protein)
• 1/2 cup unsweetened almond milk
• 1 tbsp hemp seeds
• 1 tsp matcha powder
• 1/3 cup frozen blueberries
• 1/2 tsp dulse flakes

1/2 cup rolled oats
1/2 cup Chobani plain nonfat Greek yogurt
1 scoop vanilla protein powder (25g protein)
1/2 cup unsweetened almond milk
1 tbsp hemp seeds
1 tsp matcha powder
1/3 cup frozen blueberries
1/2 tsp dulse flakes

Instructions

1. Combine oats, Greek yogurt, protein powder, almond milk, and dulse in a jar or container with a lid. Stir thoroughly — the protein powder needs to be fully incorporated or it will clump.
2. Dissolve the matcha in 1 tablespoon of the almond milk before adding it to avoid clumping. Stir or swirl into the jar — you do not need to fully incorporate it. A swirl pattern is fine.
3. Add hemp seeds. Stir once.
4. Add frozen blueberries on top. Do not stir them in — they thaw overnight and release liquid that keeps the oats moist without making them wet.
5. Seal and refrigerate for at least 6 hours. Overnight (8 hours) is ideal.
6. Eat cold, directly from the jar. If the consistency is too thick, stir in a splash of almond milk.

CRON Notes

Rolled oats, not instant. Rolled oats have a lower glycemic index than instant and absorb liquid more slowly overnight, maintaining texture without becoming mushy. They also have slightly more fiber (4g per serving versus 2-3g for instant). Steel-cut oats do not soften adequately overnight without cooking — rolled is the right call here.

Oats are moderate oxalate — within target. A half cup of dry rolled oats contains roughly 15-20mg oxalate — well within the per-meal limit of 50mg when no other moderate-oxalate ingredients are present. The low-oxalate eating rationale is more concerned with spinach and almonds than with reasonable portions of oats.

Magnesium from hemp and oats together. One tablespoon of hemp seeds provides approximately 45mg magnesium. A half cup of rolled oats provides another 55mg. Combined, these two ingredients cover 24% of the daily value (420mg for adult men) before any other sources. Magnesium deficiency affects roughly 45% of Americans and is associated with disrupted sleep quality, elevated cortisol, and impaired insulin sensitivity — all factors that matter at a caloric deficit.

Why matcha over coffee here. Both contain caffeine. Matcha provides L-theanine alongside it — the amino acid that modulates caffeine’s anxiogenic effects by promoting alpha brainwave activity. If you are eating these oats before training, the matcha provides caffeine without the sympathetic nervous system spike that can impair recovery from hard sessions. If you prefer coffee with breakfast, drop the matcha and use 1/2 cup cold brew instead of half the almond milk.

Batch prep this for five days. Five jars assembled Sunday night requires 15 minutes. Each jar is 450 calories, 45g protein, ready in the morning with no decisions required. Use a rotation of blueberries, frozen strawberries, and frozen cherries to vary the flavor across the week without rebuilding the base recipe.
