11 Low-Cal Overnight Oats Recipes To Meal Prep For Breakfast

If your mornings feel like a race you’re always losing, overnight oats might just be your new best friend. You throw everything in a jar the night before, stick it in the fridge, and wake up to a ready-to-eat breakfast that actually tastes good. And the best part? These recipes are all on the lighter side, so you’re not starting your day with a calorie bomb disguised as “healthy.”

Whether you’re trying to lose a few pounds, eat a little cleaner, or just stop making sad toast every morning, these low-cal overnight oats recipes are genuinely worth adding to your weekly meal prep. All eleven of them. Let’s get into it.

Classic Strawberry Banana Overnight Oats

This one is the crowd-pleaser. It’s simple, sweet, and tastes like something you’d actually want to eat at 7am.

You’ll need rolled oats, unsweetened almond milk, a few sliced strawberries, half a banana, and a tiny drizzle of honey if you want it. That’s basically it.

The banana adds natural sweetness so you won’t need much (if any) added sugar. The strawberries get a little jammy overnight, which is honestly one of life’s simple pleasures.

• ½ cup rolled oats
• ¾ cup unsweetened almond milk
• ½ banana, sliced
• ¼ cup strawberries, sliced
• 1 tsp chia seeds (optional but great for fiber)

Swap almond milk for oat milk if you prefer a creamier texture. Use frozen strawberries in winter — they work just as well.

This combo runs around 280–320 calories depending on your toppings, which is a solid, filling breakfast without any guilt.

Peanut Butter Chocolate Chip Overnight Oats

Yes, chocolate for breakfast. Totally valid. Especially when it’s this low in calories.

Use dark chocolate chips (just a tablespoon) and natural peanut butter to keep things on the healthier end. The peanut butter gives you protein and healthy fats, which means you’ll actually stay full until lunch.

The flavor is rich, almost dessert-like, and it makes Monday mornings feel slightly less brutal.

Mix in a little unsweetened cocoa powder if you want an even deeper chocolate flavor without extra sugar. TBH, this version tastes like eating a Reese’s cup for breakfast, and I am very much here for it.

Sub peanut butter for almond butter or sunflower seed butter if you’re dealing with a nut allergy. Works perfectly.

Blueberry Lemon Overnight Oats

This one is bright, a little tangy, and feels refreshing in a way most breakfasts don’t.

The combo of lemon zest and fresh blueberries is unexpectedly good. It tastes almost like blueberry cheesecake but without any of the damage.

Add a dollop of low-fat Greek yogurt to the mix for extra creaminess and a protein boost. The tartness of the yogurt plays really nicely against the sweet blueberries.

• ½ cup rolled oats
• ½ cup unsweetened almond milk
• ¼ cup low-fat Greek yogurt
• ½ cup blueberries
• Zest of half a lemon
• 1 tsp maple syrup

Frozen blueberries are totally fine here and often cheaper. They’ll bleed into the oats and turn everything a beautiful purple color, which is an added bonus for your breakfast aesthetic.

Apple Cinnamon Overnight Oats

If fall had a breakfast, this would be it. But honestly, this recipe works any time of year because it’s cozy without being heavy.

Dice up half an apple and stir it right into your oats with a good pinch of cinnamon and a tiny bit of nutmeg if you’re feeling fancy. By morning, the apple softens slightly and the whole thing smells amazing when you open the jar.

Use unsweetened applesauce instead of a fresh apple if you want a smoother texture throughout the oats. It blends in more evenly and makes the whole thing creamier.

Cinnamon also helps regulate blood sugar, so this is a smart choice if you’re watching your levels. Not just delicious — actually useful.

Top with a small handful of walnuts right before eating for a little crunch. Just don’t add them the night before or they’ll go soggy.

Mango Coconut Overnight Oats

Tropical vibes, low-calorie breakfast. This one feels like a treat even though it’s really not that indulgent.

Use light coconut milk instead of full-fat to keep calories in check. It still gives you that coconut flavor without going overboard. Pair it with diced mango — fresh or frozen — and you’ve got something that genuinely tastes like vacation.

A pinch of lime zest on top right before eating makes a big difference. It brightens everything up.

This is a great option if you’re dairy-free or vegan. No swaps needed — the recipe is already plant-based as written.

Around 300 calories, good fiber, and a little hit of natural sweetness from the mango. It’s a solid choice for warm weather meal prep.

Vanilla Almond Overnight Oats

Simple, clean, and kind of elegant for something you made in five minutes the night before.

Use unsweetened almond milk, a splash of pure vanilla extract, and a small handful of sliced almonds. The vanilla makes the whole thing smell like bakery goods without any of the extra sugar.

If you want to boost the protein here, stir in a scoop of vanilla protein powder. It thickens the oats beautifully and turns this into a genuinely macro-friendly breakfast.

• ½ cup rolled oats
• ¾ cup unsweetened almond milk
• ½ tsp vanilla extract
• 1 tbsp almond butter
• Sliced almonds for topping

The almond butter adds healthy fat and keeps you satisfied. Sub it for cashew butter if you want something slightly sweeter and milder in flavor.

This one is IMO the most versatile base — you can add whatever fruit or toppings you have on hand and it works every single time.

Pumpkin Spice Overnight Oats

Don’t roll your eyes. Pumpkin spice is iconic and this recipe earns its spot on the list.

Real pumpkin puree (not pumpkin pie filling — that stuff is loaded with sugar) is actually a great addition to overnight oats. It’s low in calories, high in fiber, and adds this thick, creamy texture that makes the oats feel almost pudding-like.

Mix in cinnamon, ginger, a tiny bit of cloves, and a dash of nutmeg. Sweeten with just a teaspoon of maple syrup.

This runs around 270–290 calories and is genuinely filling. The fiber from both the oats and pumpkin keeps hunger at bay for hours.

Top with a few pumpkin seeds for crunch and extra nutrition. They’re also great for adding a little protein and magnesium to your morning.

Raspberry Chia Overnight Oats

Chia seeds are the unsung hero of overnight oats and this recipe leans into them hard.

By morning, the chia seeds have absorbed the liquid and created this thick, gel-like texture that feels incredibly satisfying. Pair that with tart fresh raspberries and you’ve got a breakfast that’s pretty, delicious, and super filling.

• ½ cup rolled oats
• ¾ cup unsweetened almond milk
• 2 tbsp chia seeds
• ½ cup raspberries
• 1 tsp honey or agave

Raspberries are one of the lowest-sugar fruits out there, which makes them a great choice if you’re keeping carbs on the lower end. They’re also packed with antioxidants, so you’re doing your body a favor.

Mash half the raspberries into the oats before refrigerating and keep the other half for topping. It gives you both a swirled flavor throughout and fresh fruit on top.

Banana Bread Overnight Oats

This one tastes like banana bread but takes about three minutes to make. Life is good.

Use a very ripe banana — the browner the better — and mash it right into your oats. Add a pinch of cinnamon, a little vanilla extract, and a tablespoon of chopped walnuts. It’s warm, cozy, and deeply satisfying.

If you want to get a little extra, stir in a tablespoon of almond flour. It gives the oats a slightly nuttier, denser texture that really sells the banana bread illusion.

This is a naturally sweetened recipe with no added sugar needed (unless your banana isn’t very ripe). Keep it that way to save calories without sacrificing flavor.

Great option for kids too — it’s sweet enough to feel like a treat but genuinely nutritious.

Matcha Green Tea Overnight Oats

If you’re a matcha person, this is going to become your new morning ritual.

Whisk a teaspoon of ceremonial or culinary grade matcha powder into your almond milk before adding the oats. It gives everything a beautiful green color and a slightly earthy, grassy flavor that pairs surprisingly well with a touch of honey and vanilla.

The caffeine from the matcha gives you a gentle energy boost without the jittery feeling you sometimes get from coffee. It’s a nicer way to start the day, honestly.

Top with sliced kiwi or white sesame seeds for a clean, aesthetic breakfast bowl that looks like it belongs on Pinterest.

FYI — matcha is rich in antioxidants and has been linked to improved focus and calm energy. So you’re technically getting a functional breakfast here.

Cookie Dough Overnight Oats

We’re ending on a high note. This recipe genuinely tastes like eating cookie dough for breakfast, and somehow it’s still low in calories.

The secret is using a little almond butter, a tiny bit of maple syrup, a few mini dark chocolate chips, and a splash of vanilla extract. When it all sits together overnight, it takes on this sweet, doughy flavor that’s borderline ridiculous in the best way.

• ½ cup rolled oats
• ¾ cup unsweetened almond milk
• 1 tbsp almond butter
• 1 tsp maple syrup
• 1 tsp vanilla extract
• 1 tbsp mini dark chocolate chips

Keep the chocolate chips to just a tablespoon and you’ll stay around 320 calories. Use a sugar-free chocolate chip option if you want to cut it even further.

This is the recipe to make when you’re dreading breakfast and need a little motivation to actually eat well. It works every time.

There you have it — eleven low-cal overnight oats recipes that are worth making on repeat. The best part about meal prepping these is that you can make three or four jars at once on Sunday and have breakfast sorted for the whole week. Grab some good glass jars with lids and you’re set.

Whether you’re into fruity, chocolatey, tropical, or cozy spiced flavors, there’s something on this list for you. Start with whatever sounds most exciting, make it your own with swaps and toppings, and enjoy actually looking forward to breakfast for once.
