This crockpot pumpkin oatmeal lets you cook a whole pie pumpkin and your breakfast in the same pot while you sleep. There’s no separate roasting, peeling or chopping the pumpkin into cubes. In the morning, scoop the softened flesh and buttery, spiced juices into the steel-cut oats, mash and stir.

I love finding ways to make fresh ingredients less work, and this is one of my favorite things about this recipe: the pumpkin is much easier to scoop once it has cooked. I leave little soft pieces throughout my oatmeal because I LOVE that texture. The freshly cooked pumpkin tastes so much fresher than canned to me, and you can stir in as much or as little of the flesh as you like.

Expect warm, spoonable oatmeal with fresh pumpkin throughout. You’ll have a little scooping and stirring to do in the morning, followed by a 5–10 minute rest while you get out the bowls and toppings.

Why This Recipe Works

The pumpkin cooks with breakfast. It softens right in the crockpot, eliminating a separate roasting step.
You skip peeling and cubing a raw pumpkin. Cut off the top, clean out the seeds and let the slow cooker soften the flesh before scooping.
The pumpkin holds the good stuff. Brown sugar, butter and spices cook inside its hollow center. Stir all those juices into the oats in the morning.
You choose the texture. Leave soft pumpkin pieces like I do, mash thoroughly or purée the cooked flesh separately.
One batch makes six servings. Serve it for a family breakfast or refrigerate portions to reheat during the week.

Ingredient Notes

Pie pumpkin: Use one small pie or sugar pumpkin weighing approximately 2–3 pounds. A 2½-pound pumpkin worked perfectly for me. Choose one that fits upright inside your slow cooker with the lid completely closed. This recipe uses the hollowed pumpkin with its skin intact, rather than canned pumpkin or raw pumpkin cubes.

Steel-cut oats: Use regular steel-cut oats. Rolled oats, instant oats and quick-cooking steel-cut oats are not direct substitutes for this seven-hour method.

Water: The oats start with 3½ cups water. The pumpkin flesh and the liquid inside the cooked pumpkin get stirred in afterward, so wait until everything is combined before adjusting the consistency.

Light brown sugar: Pack it into your measuring cup, then add it inside the pumpkin. Taste the finished oatmeal before adding extra sweetener to your bowl.

Cinnamon, nutmeg and cloves: Cinnamon and nutmeg provide the warm spice flavor. The pinch of cloves is optional.

Salted butter: Cut it into pieces and place them inside the pumpkin over the sugar and spices.

Vanilla extract: Stir this into the oatmeal after cooking.

Milk or cream: Save this for serving or thinning the finished oatmeal. The overnight cooking liquid in this version is water.

Equipment You’ll Need

A 6-quart or larger slow cooker: Check the pumpkin’s fit before you begin. The lid needs to close fully without resting on the pumpkin.
A sturdy spoon: For removing seeds before cooking and scooping out the softened flesh afterward.
Oven mitts: Small silicone mitts are helpful for gripping the cooked shell. It will be hot and very soft.
A potato masher: I use my potato masher to work the cooked pumpkin into the oats. A sturdy spoon also works for breaking up very soft flesh.

How to Make Crockpot Pumpkin Oatmeal

Scooping pumpkin seeds from a hollowed pumpkin with a spoon on a wooden surface.

Prepare the pumpkin. Wash and dry a small pie pumpkin. Cut an opening around the stem large enough to reach inside with a spoon, then remove the top, seeds and stringy pulp. Leave the skin intact and discard the top.

Pouring water into a rice cooker filled with oats and grains for cooking.

Start the oatmeal. Generously coat the inside of a 6-quart or larger crockpot with cooking spray. Add the steel-cut oats and water, then stir to combine.

Cook overnight. Cover with the crockpot lid and cook on low for approximately 7 hours, until the oats are tender and the pumpkin flesh scoops easily. The oatmeal may look dry before the pumpkin and juices are stirred in, so hold off on adding more liquid.

Scoop out the pumpkin flesh. Leaving the pumpkin in the crockpot, carefully scoop the softened flesh into the surrounding oats. Add as much or as little as you like, leaving the peel behind. Spoon all the buttery, spiced juices into the oatmeal, too.

Pouring milk into a pumpkin-shaped bowl of oatmeal with pumpkin pieces.

Remove the shell. Using oven mitts, carefully lift the remaining pumpkin shell out of the crockpot. It will be very soft and may tear or lose its bottom. Remove any pieces of peel, keeping the pumpkin flesh and juices in the pot.

Mash, stir and serve. Add the vanilla and use a potato masher to work the pumpkin into the oats. Leave a few soft pieces or mash more thoroughly, depending on your preference. Stir well and let sit for 5–10 minutes. Add milk or cream as desired and serve with your favorite toppings.

Megan’s Tips for This Method

Check the fit first. Pumpkin weight is a guide, but its height and shape determine whether the lid will close.
Keep the sugar, spices and butter inside the pumpkin. They form the buttery, spiced liquid you stir into the oatmeal after cooking.
Don’t judge the oats before stirring everything together. They may look dry when you first lift the lid. Incorporate the pumpkin flesh and juices before deciding whether more liquid is needed.
Scoop gently near the skin. The cooked pumpkin is very soft. Avoid scraping so deeply that pieces of peel come away with the flesh.
A torn shell is manageable. If the bottom falls out as you lift it, remove the peel pieces and leave the flesh and liquid in the crockpot.
Use tenderness as your cue. If the pumpkin is difficult to scoop after 7 hours, cover and cook for another 15–30 minutes, then check again. Slow cookers vary.
Plan around the cooking time. This is an approximately seven-hour overnight recipe, with a few finishing steps in the morning. Don’t assume extra hours on low will give the same result.

Toppings and Texture Options

My favorite texture: Mash lightly so small, soft pieces of pumpkin remain throughout the oats.

Smooth pumpkin: Transfer the scooped flesh to a separate deep, heat-safe container and carefully purée with an immersion blender. Stir it back into the oatmeal with the pumpkin juices. Blending directly in the crockpot would purée the oats, too.

A little crunch: Add chopped pecans or granola just before serving.

Extra sweetness: Finish individual bowls with maple syrup or a sprinkle of brown sugar after tasting.

Creamier bowls: Add milk or cream a little at a time after the oatmeal rests.

How to Store and Reheat

Refrigerate leftovers in an airtight container for up to 4 days.

The oatmeal thickens as it sits. Reheat individual portions with a splash of milk or water, stirring and adding more liquid as needed until the oatmeal is hot and spoonable.

Frequently Asked Questions

What kind of pumpkin should I use?

Use a small pie or sugar pumpkin, approximately 2–3 pounds. Avoid a large carving pumpkin. Make sure it fits upright inside your crockpot with the lid fully closed.

Do I need to peel the pumpkin first?

No. Remove the top, seeds and stringy pulp, but leave the skin intact. After cooking, scoop the softened flesh into the oatmeal and remove the remaining shell.

Do I put the top back on the pumpkin?

No. Leave the pumpkin open after adding the sugar, spices and butter. Cover the crockpot with its own lid for cooking.

How much cooked pumpkin should I stir into the oatmeal?

Add as much or as little flesh as you prefer. More makes the oatmeal thicker and more pumpkin-forward. Less gives a subtler pumpkin flavor. Either way, add all the buttery, spiced liquid from inside the pumpkin.

Can I use canned pumpkin instead?

This recipe was developed around a whole pie pumpkin cooking with the oats. Canned pumpkin would change the method and moisture balance, so I don’t recommend a direct substitution with these instructions.

Can I use rolled oats or quick oats?

Use regular steel-cut oats for this version. Rolled oats, quick oats and quick-cooking steel-cut oats cook differently and aren’t interchangeable for the seven-hour timing.

Why does the oatmeal look dry when I open the crockpot?

The pumpkin flesh and its juices haven’t been incorporated yet. Scoop, mash and stir everything together first. After the 5–10 minute rest, add a splash of milk, cream or water if it is thicker than you like.

What if the pumpkin falls apart?

That can happen once the shell is very soft. Carefully remove any pieces of peel, leaving the cooked flesh and spiced juices in the oatmeal. Peel pieces may look smooth, glossy or leathery and won’t mash like the cooked flesh.

Is this the same as refrigerated overnight oats?

No. This is hot steel-cut oatmeal cooked overnight in a slow cooker. The pumpkin cooks along with the oats and gets stirred in before serving.
