Numerous days each summer, my mom pulls out a faded, yellowing index card from a small blue photo album she converted to a recipe card holder sometime during my childhood. Although she nearly knows its entire contents by heart, she still glances at it occasionally, double checking the neat cursive scrawled across its front, while measuring ingredients and adding them to different mixing bowls.
About 45 minutes later, although usually much less than that if I’m visiting their house and grab a paring knife or measuring spoons to help her, she begins pressing rich, buttery dough across the bottom and up the sides of her standard glass 9” pie plate, pours in a plethora of sweet, juicy sliced peaches coated in cinnamon and a hint of almond extract, and sprinkles a generous amount of that same buttery dough, mixed with a little extra sugar, for the final streusel topping.
When the timer rings, she and I both peer through the glass window of the oven door before sliding out the oven rack to check on Grandma’s famous peach pie. When we deem it done, she sets it on top of the stove to cool while Dad lights the coals to cook a healthy meal of veggie shish kebabs, grilled chicken, and Cajun-spiced salmon on the barbecue.
By the time we finish eating dinner, the peach pie is fully cool with its juices thickened and set, just waiting for someone to slice a knife through its fruity contents to serve the first pieces. Nobody ever pretends to be polite and simply take a sliver; we always cut extra big slices, which seem to magically disappear in a matter of seconds from our plates, before we head back for seconds.
Regardless of how many people are at the house, whether it’s simply the four of us or additional company as well, Grandma’s peach pie never lasts more than 24 hours. With it sitting on the counter, a reminder of last night’s dessert and practically begging us to eat a little more, we almost always sneak a sliver after breakfast (it contains fruit!)… a small slice after lunch… a nibble or two as a snack… and if there’s any left by the time dinner rolls around the following evening, we polish off every last crumb from the pie plate after that meal.
Grandma’s peach pie is just that good!
Because I’m still trying to create a lightened up version (her recipe includes a lot of butter!), and because I know I’ll be tempted to eat a slice for breakfast the next time we bake it, I planned ahead and created this wholesome recipe for…
Healthy Peach Pie Protein Overnight Oats! These oats have the same irresistible sweet, summery flavor of Grandma’s famous pie, but they’re definitely healthy enough for breakfast. Even better, they require just 6 ingredients and less than 5 minutes to whip up — which makes my lazy side and my taste buds very happy!
HOW TO MAKE HEALTHY PEACH PIE PROTEIN OVERNIGHT OATS
Like I mentioned, overnight oats are extremely easy to make! You simply mix together the ingredients in a mason jar or airtight container, seal the lid on tight, and place that in the refrigerator until morning. When you wake up the next day, your healthy breakfast will be ready and waiting — all that’s left to add is your spoon!
So yes, overnight oats are meant to be eaten cold, straight from the fridge! No need to heat them up. Letting the oats sit in the mixture of liquid ingredients allows them to soften as much as if you had cooked them on the stove or in the microwave. That’s part of their charm — there’s almost no prep work involved!
INGREDIENTS TO MAKE HEALTHY PEACH PIE PROTEIN OVERNIGHT OATS
You can probably guess the first key ingredient… Oats! Both old-fashioned rolled oats and instant oats will work in this recipe. Instant oats are also known as “quick-cooking” and “one-minute oats,” and they’re sold in containers near the regular old-fashioned rolled oats. (They are not the same thing as those individual packets with flavors like apple cinnamon and maple brown sugar!) They only contain one ingredient — oats! — and they’re simply smaller and thinner than old-fashioned rolled oats.
Tip: To make your healthy peach pie protein overnight oats gluten-free, use certified gluten-free old-fashioned rolled oats or certified gluten-free instant oats. They work perfectly!
However, do not use steel-cut oats! Those don’t soften properly and remain hard and crunchy, no matter how long you leave the jar in the fridge.
To make this overnight oatmeal thick and creamy, you’ll use one of my favorite ingredients: Greek yogurt. Greek yogurt contains around 21g of protein per cup, compared to regular yogurt with around 10g, so it gives these oats a huge protein boost. It’s a great way to sneak in extra protein and keep your tummy feeling full all morning long!
You’ll also stir in a splash of milk to achieve the perfect overnight oatmeal consistency. Just about any type will work, so feel free to use whatever your already have in your fridge!
To give these oats a little extra sweetness, you’ll use another one of my favorite ingredients: liquid stevia. Stevia is a plant-based, no-calorie sweetener that’s clean eating friendly, and it’s very concentrated. A little goes a long way! You’ll only need ¼ teaspoon for the entire jar of oats.
This is the kind that I buy because I love its sweet flavor and don’t detect any strange aftertaste the way I sometimes do with other stevia products. You can find it at many health-oriented grocery stores, but I typically buy it online online because that’s generally the best price I’ve found. (And you’ll use it in all of these recipes of mine, too!)
Tip: Many stevia brands and products have different sweetness levels, so they’re not necessarily 1-for-1 substitutes for each other. If you pick a different brand or product, rather than the one I use, you may need to adjust the amount!
And of course, we can’t forget the pie flavors! Those come from diced peaches and cinnamon. Cinnamon was my grandma’s secret trick to making her pie filling so irresistible, so I always add it to all of my peach recipes! As for the peaches, I highly recommend using fresh if they’re in season, but peaches that have been canned in 100% juice and thoroughly drained will work as well.
Then mix everything together, pop it in the fridge, go to sleep, and…
Breakfast is served! And when you make your own, remember to snap a picture and share it on Instagram using #amyshealthybaking and tagging @amyshealthybaking IN the photo itself. (That guarantees that I’ll see the notification from you! 🙂 ) I’d love to see your healthy peach pie protein overnight oats!

Amy is there ANY chance you’ve shared your Grandma’s Peach Pie recipe anywhere? We don’t make pie here in Australia like you guys do and I’d love to try baking a true American Peach Pie!
You’re so sweet, Hayley! I really appreciate your interest in my grandma’s peach pie recipe. I haven’t yet perfected a healthy version of her entire pie, so I’m afraid I haven’t shared it anywhere on my website.
My peach crumble recipe has a very similar filling and and also has a crumb topping like her pie, and my peach crumble bars recipe has similar flavors as well (just a soft and thick cookie-like “crust” instead of her shortbread-style one). Maybe one of those might be of interest? I completely understand that bars, crumbles, and pies are different and those options might not satisfy your craving though! I thought I’d mention them, just it in case. 🙂
Hah! I get it and I try to be healthy most of the time, however there are times when I think it’s okay to go to the dark side and have something truly indulgent! And your grandma’s authentic Peach Pie would definitely for into that category!
Still, I will placate myself with one of your healthier peach offerings above ☺️
You read my mind, Hayley! Family recipes are usually like that for me too. 😉 I can’t wait to hear which one you pick to make!
Made the Peach Pie Overnight Oats last night and devoured this morning. Delicious! I will add a little more cinnamon spice next time. (just because I love my spices)
I also sprinkled a a few dried coconut flakes over the top just before serving ❤️
Made with home made yoghurt, it was just the ticket for a fresh breakfast ❤️
I’m so happy you enjoyed them, Hayley! I’m a big fan of spices and often add more too. Great minds? 😉 The dried coconut sounds like a fun twist, along with the homemade yogurt. I’m so impressed that you make your own!
Thank you for taking the time to leave another sweet comment and rate this recipe too. It truly means a lot! ♡
PS Have you tried Saigon cinnamon? If not, it’s a bit stronger, richer, and sweeter than regular cinnamon. It’s basically the only kind I use now because I love the extra boost of flavor it adds. I just thought I’d mention it in case you love spices as much as I do! 🙂
No I haven’t heard of Saigon Cinnamon but will certainly check that out. My other true love is Cinnamon Rolls so that would do well in my recipe for those too.
Home made yoghurt is so easy and next level yum! And so much cheaper than store bought.
Just 1 litre of whole milk, 50 gms of powdered milk and a couple of grains of culture (kept in the freezer). Into the electric incubator for 10-12 hrs, then into the fridge to set for a few hours and presto! So creamy and delicious. And only a couple of $ as opposed to $6-7 store bought. No preservatives and no sugar but every bit as sweet and twice as tasty 💕
I hope you’re able to find some Saigon cinnamon, Hayley! I’d send you a link for my favorite kind, but I don’t know that it’s available in Australia. Cinnamon rolls were one of the first things I made when I bought my first jar, and they turned out beautifully. I hope yours do too!
You make it sound so easy! It’s very tempting to dive into that and give it a try… Thank you for sharing!!
