25 High-Protein Overnight Oats Under 350 Calories

Breakfast shouldn’t require you to be a morning person — and yet here we are.

You’ve probably stared at your kitchen at 7 a.m., half-awake, knowing you should eat something real before the day eats you alive. You want something filling, something that won’t blow your calories before noon, and ideally something that doesn’t taste like cardboard soaked in regret. That’s exactly what these 25 high-protein overnight oats deliver — pre-made, macro-friendly, and genuinely delicious. Let’s get into it.

Why High-Protein Overnight Oats Actually Work (Not Just Hype)

Here’s the counterintuitive truth: oats alone won’t keep you full. A plain bowl of rolled oats clocks in around 5–6g of protein, which sounds decent until you realize it’ll leave you raiding the office snack drawer by 10 a.m. The real magic of overnight oats comes from what you add — Greek yogurt, protein powder, cottage cheese, nut butters — ingredients that push your breakfast into the 20–35g protein range without blowing past 350 calories.

25 High-Protein Overnight Oats Under 350 Calories

Research consistently shows that high-protein breakfasts reduce overall daily calorie intake by curbing hunger hormones like ghrelin. So you’re not just eating smart at breakfast — you’re quietly setting up every meal that follows. If you’re already working on building better eating habits, the 30-Day Low-Calorie High-Protein Breakfast Challenge is a great companion to this list.

I used to think overnight oats were just a Pinterest trend for people who owned too many mason jars. I was wrong. Once I started actually tracking my protein and noticed how much steadier my energy was on days I ate a high-protein breakfast versus a high-carb one, I became a full convert. Slightly embarrassing but completely true.

The Overnight Oats Formula You Need to Know First

Before we get into the 25 recipes, here’s the base formula that makes every single one of these work:

½ cup rolled oats (~150 cal, 5g protein)
½ cup Greek yogurt (~65 cal, 9–11g protein)
½ cup unsweetened almond milk or skim milk
1 scoop protein powder (optional but powerful — adds 20–25g protein for ~100 cal)
Toppings and flavors (this is where the personality comes in)

Mix, refrigerate overnight, eat cold or warmed up. That’s it. The entire process takes four minutes. You’re welcome.

Category 1: The Classics Done Right

1. Vanilla Protein Overnight Oats

Mix ½ cup oats, ½ cup non-fat Greek yogurt, ½ cup almond milk, 1 scoop vanilla protein powder, and ½ tsp vanilla extract. Top with a few blueberries in the morning. Calories: ~290 | Protein: ~32g — Get the full recipe →

2. Chocolate Peanut Butter Oats

Stir ½ cup oats, ½ cup Greek yogurt, 1 tbsp powdered peanut butter (PB2), ½ scoop chocolate protein powder, and a drizzle of sugar-free chocolate syrup. This one tastes genuinely indulgent. Calories: ~315 | Protein: ~28g — Get the full recipe →

3. Banana Cinnamon Oats

Mash half a ripe banana into ½ cup oats with ½ cup Greek yogurt, a dash of cinnamon, and ½ cup skim milk. No protein powder needed here — the yogurt carries it. Calories: ~280 | Protein: ~20g — Get the full recipe →

4. Strawberry Cheesecake Oats

This sounds too good to be under 350 calories, and yet. Mix ½ cup oats, ¼ cup non-fat cream cheese, ¼ cup Greek yogurt, ½ cup almond milk, and a few sliced strawberries. Calories: ~310 | Protein: ~22g — Get the full recipe →

5. Plain Jane Powerhouse

Don’t underestimate simplicity. Half a cup of oats, ½ cup cottage cheese (yes, cottage cheese — trust me), ½ cup milk, and a drizzle of honey. Cottage cheese blends in overnight and disappears into the texture completely. Calories: ~270 | Protein: ~25g — Get the full recipe →

Pro Tip: Cottage cheese is one of the most underrated protein sources in overnight oats. It melts into the texture overnight, adds 14g of protein per ½ cup, and you’d never guess it was there. If you’ve been sleeping on cottage cheese, it’s time to wake up.

Category 2: For the Fitness Crowd (Gains-First Energy)

These recipes are built for people who train, whether that’s early morning lifts, lunchtime runs, or evening HIIT classes. They lean heavier on protein and keep carbs strategic. If you’re prepping for the week, check out these high-protein low-calorie meal prep ideas for athletes for a broader strategy.

6. Post-Workout Vanilla Almond Recovery Oats

½ cup oats, 1 scoop vanilla whey protein, ½ cup almond milk, 1 tbsp almond butter (measured — it adds up), topped with sliced almonds. Calories: ~340 | Protein: ~34g — Get the full recipe →

7. Mocha Pre-Workout Oats

Cold brew concentrate + oats + chocolate protein powder = breakfast that doubles as your morning coffee. Add ½ cup Greek yogurt and you’ve got a genuinely caffeinated, high-protein start. Calories: ~300 | Protein: ~29g — Get the full recipe →

8. Egg White Protein Oats (Yes, Really)

Pasteurized liquid egg whites mixed into oats before refrigerating overnight cook slightly from the ambient warmth and create an incredibly thick, creamy texture. Add vanilla extract and cinnamon to make it taste like actual food, not a gym experiment. Calories: ~265 | Protein: ~30g — Get the full recipe →

9. Casein Protein Overnight Oats

Casein protein powder (the slow-digesting kind) is actually made for overnight oats — it thickens beautifully and keeps you full for hours. Mix with ½ cup oats, ½ cup almond milk, and berries. Calories: ~290 | Protein: ~33g — Get the full recipe →

10. Greek Yogurt Double-Layer Oats

Layer the oats and yogurt separately before refrigerating, then stir in the morning for a thick, textured bowl. Adding a teaspoon of flaxseed quietly boosts omega-3s without affecting taste at all. Calories: ~305 | Protein: ~26g — Get the full recipe →

Why This Works: Layering before combining changes the texture of your oats, not just the look. The yogurt layer stays denser, giving you a contrast of thick and creamy in each bite. It’s a small detail that makes a boring breakfast feel like something you actually chose.

Quick reality check: you don’t need to be training for a marathon for these to be worth making. These are just good breakfasts. Filling, fast, and they won’t make you hate mornings quite as much. 😄

Category 3: Sweet Tooth, Controlled

Craving something that feels like dessert but isn’t a nutritional disaster? These are your people-pleasers. IMO, this category is what converts overnight oat skeptics faster than anything else.

11. Tiramisu Overnight Oats

Espresso, cocoa powder, mascarpone (just 1 tbsp goes a long way), vanilla protein powder, and oats. Tastes like you have your life together. Calories: ~320 | Protein: ~24g — Get the full recipe →

12. Lemon Blueberry Cheesecake Oats

Lemon zest, fresh blueberries, non-fat cream cheese, ½ cup oats, and Greek yogurt. Bright, refreshing, and something you’d actually look forward to waking up for. Calories: ~285 | Protein: ~21g — Get the full recipe →

13. Cinnamon Roll Oats

Heavy on the cinnamon, a touch of vanilla, maple extract (not maple syrup — the extract is calorie-free), Greek yogurt, and oats. Drizzle with a tiny bit of cream cheese thinned with almond milk as a “frosting.” Calories: ~295 | Protein: ~22g — Get the full recipe →

14. Pumpkin Spice Oats (Unapologetically)

Yes, it’s basic. No, I won’t apologize. Pumpkin puree adds fiber and volume for almost zero calories. Add pumpkin spice blend, Greek yogurt, protein powder, and you’ve got a fall-flavored breakfast that actually earns its reputation. Calories: ~310 | Protein: ~27g — Get the full recipe →

15. Cookie Dough Protein Oats

The secret ingredient: a tiny bit of almond flour. It gives the oats that slightly grainy, doughy texture that mimics cookie dough. Add mini chocolate chips (just 1 tbsp keeps calories honest), vanilla protein powder, and Greek yogurt. Calories: ~335 | Protein: ~28g — Get the full recipe →

Pro Tip: Mini chocolate chips feel more indulgent than regular-sized chips because you get more pieces per tablespoon. Your brain registers abundance. This is legitimate food psychology, and you should absolutely use it to your advantage.

Category 4: Plant-Based Protein Powerhouses

FYI — you absolutely don’t need dairy or whey to hit strong protein numbers with overnight oats. This category proves it. If you’re building a fully plant-based routine, the 25 High-Protein Low-Calorie Vegan Meals list is worth bookmarking.

16. Hemp Seed and Chia Protein Oats

3 tbsp hemp seeds (10g protein, zero fuss) + 1 tbsp chia seeds + oats + coconut milk. No protein powder required. Top with sliced banana and a drizzle of tahini. Calories: ~330 | Protein: ~20g — Get the full recipe →

17. Soy Milk Protein Oats with Almond Butter

Soy milk has the highest protein content of any plant milk (~7–8g per cup). Combine with ½ cup oats, 1 tbsp natural almond butter, and a scoop of plant-based protein powder for a fully vegan bowl that punches above its weight. Calories: ~320 | Protein: ~29g — Get the full recipe →

18. Edamame Protein Oats (the Wildcard)

Before you close this tab — hear me out. Blended edamame (cooked, then blended smooth) stirred into oats is completely tasteless in the final product but adds 8–9g of plant protein per ¼ cup. Add vanilla, sweetener, and berries on top and you’d never know. Calories: ~295 | Protein: ~24g — Get the full recipe →

19. Tofu Mousse Oats

Silken tofu blended with cocoa powder and a touch of maple syrup creates a chocolate mousse layer that sits on top of plain oats overnight. Incredible texture. Zero dairy. Calories: ~280 | Protein: ~22g — Get the full recipe →

20. Pea Protein Chocolate Oats

Pea protein powder has a slightly earthy flavor that chocolate overwhelms beautifully. Combine with oats, almond milk, a banana, and cocoa powder. Clean, vegan, surprisingly rich. Calories: ~310 | Protein: ~30g — Get the full recipe →

Why This Works: Pea protein has a complete amino acid profile and digests slower than whey, which means more sustained fullness. If you’ve ever had a whey protein breakfast and felt hungry again in 90 minutes, pea protein is worth switching to — or at least trying.

Category 5: Savory Overnight Oats (for the Truly Adventurous)

Okay, I know. I know. Savory overnight oats sound like something a food blogger invented just to be different. But tbh, once you try one, the idea of everything being sweet in the morning starts to feel a little exhausting.

21. Miso and Sesame Overnight Oats

White miso, sesame oil (just ½ tsp), soy milk, and oats. Top with a soft-boiled egg in the morning for +6g protein and a bowl that genuinely feels like a warm, nourishing meal. Calories: ~310 | Protein: ~23g — Get the full recipe →

22. Spinach and Egg White Overnight Oats

Blend a handful of spinach into almond milk before mixing with oats — the oats turn green, yes, but taste completely neutral. Add 3 tbsp pasteurized egg whites and season with garlic powder and black pepper. Calories: ~265 | Protein: ~26g — Get the full recipe →

23. Parmesan and Sun-Dried Tomato Oats

This one surprised me most. Steel-cut oats soaked overnight with parmesan, sun-dried tomatoes, and chicken broth instead of milk. Reheat in the morning, top with a poached egg. Full Italian breakfast energy under 350 calories. Calories: ~340 | Protein: ~25g — Get the full recipe →

Category 6: The Last Three — Saved the Best for This

24. High-Protein Snickers Oats

Peanut flour, a few mini dark chocolate chips, caramel extract, and vanilla protein powder layered into oats with Greek yogurt. Tastes like a candy bar. 28 grams of protein. Absolutely no business being this good at this calorie count. Calories: ~330 | Protein: ~28g — Get the full recipe →

25. Cottage Cheese Birthday Cake Oats 🎂

This is the one people screenshot and send to friends. Cottage cheese blended smooth (so the texture becomes indistinguishable from cream), mixed with oats, vanilla protein powder, rainbow sprinkles (yes, they’re allowed — 1 tsp is 15 calories), and almond milk. It tastes like birthday cake batter. It has 31 grams of protein. It is under 350 calories. I’ve made this on a Tuesday morning with zero occasion and felt genuinely celebratory about it. Calories: ~325 | Protein: ~31g — Get the full recipe →

Quick-Start: How to Meal Prep All 25 at Once

If you’re going to make one of these, you might as well make five. Overnight oats keep in the fridge for up to five days, and the prep time per jar is about three minutes once you have a system. If you’re building a full week of high-protein mornings, the 15 High-Protein Breakfasts Under 350 Calories list pairs perfectly with this one to round out your options.

A few batch-prep rules that actually matter:

Keep wet and crunchy toppings separate until morning
Use wide-mouth mason jars — narrow jars are a stirring nightmare
Label jars by flavor unless you enjoy mystery (some people do)
Add fresh fruit in the morning only — it gets weird after day two

The entire week’s worth of breakfasts can be prepped in under 30 minutes on a Sunday. That’s it. That’s the whole commitment.

What to Do if You Hate the Texture of Cold Oats

Some people genuinely can’t do cold oats — the texture bothers them, and that’s a completely valid human experience. The fix is simple: microwave for 60–90 seconds in the morning, stir, and eat warm. Every single recipe on this list works heated. The protein content doesn’t change, the flavor gets slightly more intense, and if you were on the fence about overnight oats for textural reasons, this might be the reframe you needed.
