The first time I made this pumpkin spice overnight oats jar, I knew it was pure comfort in a jar. It tastes cozy, creamy, and just sweet enough, so it feels like a little fall treat without any fuss. Best of all, it is the kind of breakfast that welcomes you back in the morning with almost no work at all.
This recipe blends old-fashioned rolled oats, whole milk or unsweetened almond milk, canned pumpkin puree, pure maple syrup, pumpkin pie spice, vanilla, fine sea salt, and plain Greek yogurt into a thick and creamy base. Then it gets finished with toasted pecans, granola, and a little whipped cream if you like. The flavor is warm, lightly sweet, and gently spiced, with the pumpkin adding color, body, and a mellow autumn taste.
The method could not be easier. You whisk the base together, stir in the oats, divide everything into jars, and chill overnight. In the morning, the oats are soft, spoonable, and ready to eat. Since the recipe takes just 10 minutes of active prep time, it is a smart make-ahead breakfast for busy weekdays or slow weekends. It also makes 4 jars, which is helpful if you like to plan ahead.
This is a wonderful breakfast for chilly mornings, but honestly, it works all year. It is especially nice for grab-and-go breakfasts, meal prep Sundays, or even a relaxed brunch with family. Because the jars keep well in the fridge, they are also great for anyone who wants a wholesome breakfast ready without any morning stress.

Pumpkin Puree Tips
The key ingredient here is canned pumpkin puree. For the best result, choose plain pumpkin puree, not pumpkin pie filling. Pie filling already contains sugar and spices, and that can make the oats too sweet. Also, look for puree with a smooth texture and a deep orange color. If the puree seems watery, give it a quick stir before measuring. That way, the flavor stays balanced and the oats thicken nicely.
Options for Substitutions
- Swap whole milk for unsweetened almond milk, oat milk, or soy milk if you want a dairy-free base.
- Use coconut yogurt instead of Greek yogurt for a dairy-free option with extra creaminess.
- Replace pure maple syrup with honey or agave, if that better fits your pantry.
- Use pumpkin pie spice plus a little extra cinnamon if you do not have the blend on hand.
- Swap toasted pecans for chopped walnuts, almonds, or pumpkin seeds.
- Use gluten-free granola if you need the topping to stay gluten-free.
Watch Out for These Mistakes
First, do not use pumpkin pie filling by accident. It may seem close, but it is not the same thing. Since it already contains added sugar and spices, the final flavor can turn overly sweet and a little muddy. Instead, use plain pumpkin puree for clean pumpkin flavor and better control over the taste.
Second, make sure the oats are fully mixed into the liquid. If some oats stay dry on top, they will not soften evenly overnight. Also, use old-fashioned rolled oats, not instant oats. Instant oats can become mushy, while steel-cut oats will stay too firm unless you change the method.
Third, do not skip the chill time. The oats need at least 6 hours, and overnight is even better. During that time, the oats absorb the liquid and become thick and creamy. If you rush this step, the texture will be thin and the oats will taste underdone.
Finally, remember to stir before serving. Overnight oats can separate a bit in the fridge, which is completely normal. If the mixture feels too thick in the morning, add a splash of milk and stir again. That small step helps the texture turn smooth, spoonable, and pleasant to eat.
What to Serve With Pumpkin Spice Overnight Oats Jar?
This pumpkin spice overnight oats jar pairs nicely with simple sides like fresh berries, sliced apples, hard-boiled eggs, or a warm cup of coffee or tea. For a fuller breakfast, you could add turkey sausage, a banana, or a small bowl of cottage cheese. Since the oats are soft and lightly sweet, the best partners are foods that bring freshness, protein, or a little crunch.
Storage Instructions
Store: Keep the jars covered in the refrigerator for up to 5 days. For the best texture, store the toppings separately if possible and add them right before serving.
Freeze: You can freeze overnight oats for up to 2 months, although the texture may soften a bit more after thawing. For best results, freeze without toppings and use freezer-safe jars with room at the top.
Reheat: To reheat on the stovetop, place the oats in a small saucepan over low heat and warm gently, stirring often. For the microwave, heat in short bursts of 30 to 45 seconds, then stir and repeat if needed. Add a splash of milk if the oats seem too thick.

Ingredients
- 2 cups old-fashioned rolled oats
- 2 cups whole milk (or unsweetened almond milk)
- 1/2 cup canned pumpkin puree (not pumpkin pie filling)
- 1/4 cup pure maple syrup
- 1 tsp pumpkin pie spice
- 1/2 tsp pure vanilla extract
- 1/4 tsp fine sea salt
- 1/2 cup plain Greek yogurt
- For topping: 1/4 cup toasted pecans, chopped
- 2 tbsp granola
- whipped cream (optional)
- extra maple syrup and a pinch of pumpkin pie spice, for garnish
Step-by-Step Instructions
Step 1: Whisk the Pumpkin Base
In a large bowl or liquid measuring cup, whisk together the milk, pumpkin puree, maple syrup, pumpkin pie spice, vanilla, and salt until the mixture looks smooth and fully blended. This step helps the spices spread evenly, and it also keeps the pumpkin from clumping.
Step 2: Add the Greek Yogurt
Whisk in the Greek yogurt until no streaks remain. This makes the mixture creamier, and it also adds a nice tang that balances the maple syrup and pumpkin. Because of the yogurt, the finished oats feel rich without being heavy.
Step 3: Stir in the Oats
Add the rolled oats and stir until they are fully coated in the liquid. Make sure every oat is submerged, because that helps them soften evenly overnight. If needed, scrape the bottom and sides of the bowl so nothing gets left behind.
Step 4: Divide and Chill
Divide the mixture evenly among 4 pint-sized mason jars or airtight containers. Then cover each jar with a lid and place them in the refrigerator for at least 6 hours, or overnight. During that time, the oats will slowly absorb the liquid and turn thick, creamy, and soft.
Step 5: Stir, Top, and Serve
The next morning, stir each jar well before serving, since the mixture may settle a little while chilling. If the oats seem too thick, add a splash of milk and stir again. Finish with chopped toasted pecans, a spoonful of granola, and whipped cream if you want it. Then drizzle with extra maple syrup and a small pinch of pumpkin pie spice. You can eat it cold right from the jar, or warm it gently in the microwave for 30 to 45 seconds.
Conclusion
This pumpkin spice overnight oats jar is simple, cozy, and very practical. It uses basic ingredients, takes only 10 minutes of active prep time, and gives you a creamy breakfast that is ready when you wake up. Because it stores well, it is a great choice for meal prep, busy mornings, or anyone who wants a warm fall flavor without cooking.
