Pumpkin pie overnight oats are what happens when dessert-for-breakfast finally grows up. You stir pumpkin puree, rolled oats, Greek yogurt, and a pumpkin pie spice blend together in five minutes, then let the fridge do the work while you sleep. By morning the oats are thick, creamy, and taste almost exactly like the custard filling of a Thanksgiving pie.
The trick is balancing the pumpkin. Too much puree and the oats turn dense and vegetal; too little and you just have cinnamon oatmeal. This version uses a measured ratio plus a spoon of maple syrup and a pinch of salt to pull the squash into dessert territory without any added sugar overload.
I make a batch of six jars every Sunday in September and October, and they hold beautifully through Friday. Serve them cold straight from the jar, or warm them gently on the stove for a cozy version that mimics fresh pie.
Why You'll Love This Recipe
About the Ingredients
2 1/4 cups (200g) old-fashioned rolled oats
Use rolled oats, not quick oats or steel-cut; quick oats turn to paste overnight and steel-cut stay crunchy. If you only have quick oats, reduce the milk by 1/4 cup and eat within two days.
1 1/2 cups (360ml) whole milk
Whole milk gives the creamiest result, but unsweetened oat milk or almond milk works one-for-one. If using a thin plant milk, add 2 extra tablespoons of Greek yogurt for body.
1 cup (245g) canned pumpkin puree
Buy 100% pure pumpkin, not pumpkin pie filling, which is pre-sweetened and spiced. One 15-ounce can holds about 1 3/4 cups, so you will have leftovers for a second batch or a smoothie.
1 cup (245g) plain whole-milk Greek yogurt
Full-fat Greek yogurt adds tang and thickness; 2% works but gives a looser jar. For a dairy-free version, use a thick coconut or soy yogurt and add 1 teaspoon lemon juice for tang.
1/3 cup (80ml) pure maple syrup
Grade A dark amber maple syrup has the deepest flavor here. Honey or brown sugar can substitute, but brown sugar will not dissolve as evenly in cold milk.
1 1/2 teaspoons pumpkin pie spice
If you are out, whisk 1 teaspoon cinnamon, 1/4 teaspoon ginger, 1/4 teaspoon nutmeg, and a pinch each of cloves and allspice. Freshly grated nutmeg makes a noticeable difference.
1 teaspoon vanilla extract
Real vanilla extract, not imitation, keeps the flavor clean against the spice. A 1/2 teaspoon of vanilla bean paste is a lovely upgrade if you have it.
1/4 teaspoon fine sea salt
Do not skip this; salt is what makes the pumpkin taste sweet instead of flat. Fine sea salt dissolves better than flaky kosher salt in a cold mixture.
1/2 cup (60g) chopped pecans or walnuts, plus more for serving
Toast the nuts in a dry skillet over medium heat for 3 to 4 minutes until fragrant for a deeper flavor. Pepitas are a great nut-free swap and add a green-flecked crunch.
Tips & Tricks
Let them sit a full 8 hours
Two hours in the fridge gives you gritty, milky oats. Overnight hydration is what turns rolled oats soft and custardy, so mix them before bed, not before your shower.
Stir before you eat
The oats settle and the liquid rises, so a quick stir recombines everything into that creamy pie-filling texture. If a jar looks too thick, splash in a tablespoon of milk.
- Do not use pumpkin pie filling by mistake: It looks nearly identical to pure pumpkin on the shelf but is already sweetened and spiced, so your oats will taste cloying and over-spiced. Read the label for the single word 'pumpkin' as the only ingredient.
Pro Tips
Step-by-Step Instructions
1. Whisk the wet base
In a large bowl, whisk the pumpkin puree, Greek yogurt, milk, maple syrup, vanilla, pumpkin pie spice, and salt until completely smooth with no streaks of orange or white. This takes about 2 minutes and ensures every jar tastes the same.
2. Fold in the oats
Add the rolled oats and chopped pecans and stir until every oat is coated and the mixture looks like a thick, wet batter. It will seem loose now; that is correct, because the oats will absorb about a third of the liquid overnight.
3. Portion into jars
Divide the mixture evenly among six 8-ounce jars or lidded containers, filling each about three-quarters full to leave room for toppings. A wide-mouth canning funnel keeps the rims clean.
4. Chill overnight
Seal the jars and refrigerate for at least 8 hours or up to 5 days. The oats are ready when they are soft, spoonable, and hold a gentle mound on the spoon rather than pooling liquid.
5. Toast the topping
If you want warm, fragrant nuts, toast the extra pecans in a dry skillet over medium heat at 350F (175C) for 3 to 4 minutes, stirring often, until they smell nutty and turn one shade darker. Watch closely, because nuts go from toasted to burnt in under 30 seconds.
6. Serve and finish
Stir each jar, add a splash of milk if you like a looser texture, and top with toasted pecans and an extra dusting of pumpkin pie spice. Eat cold, or warm gently in a saucepan over low heat at 200F (95C) for 4 to 5 minutes until steaming but not bubbling.
Delicious Variations
Pumpkin Pie Protein Oats
Swap the Greek yogurt for 1 cup vanilla protein powder blended with 1 1/4 cups milk, adding 20g protein per jar.
Chocolate Pumpkin Oats
Stir 2 tablespoons unsweetened cocoa powder and 1 extra tablespoon maple syrup into the base for a brownie-meets-pumpkin flavor.
Vegan Pumpkin Oats
Use oat milk and a thick coconut yogurt, and replace the maple syrup with agave if you prefer a lighter sweetness.
How to Store Pumpkin Pie Overnight Oats
Refrigerator
Store sealed jars in the refrigerator for up to 5 days; stir before eating and add a splash of milk if they thicken too much.
Freezer
Freeze individual jars for up to 2 months, leaving 1 inch of headspace; thaw overnight in the refrigerator before eating.
Reheating
Warm a single jar in a saucepan over low heat at 200F (95C) for 4 to 5 minutes, stirring, until steaming; or microwave in 30-second bursts, stirring between each, for about 90 seconds total.
Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?
Yes, but reduce the milk by 1/4 cup because quick oats absorb less liquid and soften much faster. Quick oats will be ready in as little as 2 hours and turn mushy by day three, so eat those jars first.
Q: How long do pumpkin pie overnight oats last in the fridge?
They stay fresh for up to 5 days in a sealed jar in the refrigerator. After day five the oats get very soft and the flavor dulls, so label the jars with the date you made them.
Q: Are pumpkin pie overnight oats healthy?
They are a balanced breakfast with about 285 calories, 12 grams of protein, and 5 grams of fiber per serving from the oats, pumpkin, and yogurt. The maple syrup adds sugar, so reduce it to 3 tablespoons if you are watching your intake.
Q: Can I eat overnight oats warm?
Absolutely, and warm pumpkin oats taste remarkably like fresh pie filling. Heat a jar gently in a saucepan over low heat at 200F (95C) for 4 to 5 minutes, or microwave in 30-second bursts, stirring until steaming.
Q: Why are my overnight oats watery?
You likely used too much milk or a thin plant milk, or you did not let them sit long enough. Stir in 2 extra tablespoons of Greek yogurt or 1 tablespoon chia seeds and chill another hour to thicken them up.
Mix a batch of pumpkin pie overnight oats tonight and wake up to dessert for breakfast all week. Grab six jars, your can of pumpkin, and five minutes, then tell me in the comments whether you ate yours cold or warm.
