Slow Cooker Pumpkin Steel Cut Oats (Pumpkin Pie Oatmeal)
Slow cooker pumpkin steel cut oats are what happens when pumpkin pie becomes a reasonable breakfast. Real pumpkin, warm spices and a little maple syrup cook low and slow with steel cut oats until the batch is thick, creamy and tender, with just enough chew left to remind you these are oats.
You don’t need to be a morning cook, or any kind of cook, to make this. Five minutes of stirring before bed is the whole job. The slow cooker handles the rest while you sleep, and one batch covers four breakfasts.
If cold overnight oats stop sounding appealing the second fall arrives, this is their cozier cousin.
Why This Works
Steel cut oats can handle a long cook
Rolled and quick oats turn to paste after six-plus hours in a slow cooker. Steel cut oats are whole oat groats chopped into pieces, so they soften slowly and still have texture at the end.
Real pumpkin does more than add flavor
Pumpkin puree makes the oatmeal creamier, adds fiber and turns a plain pot of oats into something that tastes like pie filling. Pumpkin pie spice on its own only gets you halfway there.
The prep happens when you have time
Five minutes at night replaces twenty minutes of stovetop stirring in the morning. That’s the whole trade, and it’s a good one.
One batch, four breakfasts
Make it once, portion it out and reheat a bowl in about two minutes for the rest of the week.
The sweetness is adjustable
Three tablespoons of maple syrup across the whole batch is enough to read as pumpkin pie. Anyone who wants it sweeter can add more at the table.
How Overnight Slow Cooker Oatmeal Works
Steel cut oats need about 6 to 7 hours on LOW in most slow cookers. That lines up almost exactly with a night’s sleep, which is the whole appeal. It’s also the whole risk, since most people are asleep closer to 8 hours.
Three things decide whether you wake up to creamy oatmeal or a scorched ring around the crock:
- Timing. Aim for 6 to 7 hours on LOW. A programmable slow cooker that switches to warm when the timer ends covers the gap between when the oats are done and when you’re awake.
- Liquid ratio. This recipe uses 4 cups of liquid (half milk, half water) for every cup of steel cut oats, plus a cup of pumpkin. If your slow cooker runs hot, or the oats will sit closer to 9 hours, add an extra ½ cup of water.
- Crock size. A 3- to 4-quart slow cooker is the right size for one batch. In a 6- or 7-quart crock, the mixture spreads thin and the edges brown before the center is ready.
[TEST NOTE — add after testing: how the batch looked at 6, 7 and 8+ hours, whether the edges browned or stuck, and whether the 1:4 ratio needed adjusting.]
If you’re shopping for a smaller programmable cooker, the Beautiful 4-quart programmable slow cooker has a nonstick pot and an automatic keep-warm setting, and it comes in the same soft colors as these colored kitchen appliances. The Crock-Pot 4-quart programmable Cook and Carry is the classic option, with a locking lid and the same switch-to-warm timer.
Pumpkin Steel Cut Oats Ingredients
Eight pantry ingredients, all from a regular grocery store.
Steel cut oats
Use traditional steel cut oats, not quick-cooking steel cut oats or rolled oats, since they need the long cook to soften properly. Bob’s Red Mill Steel Cut Oats are easy to find, and Bob’s also makes gluten-free steel cut oats if you need certified gluten-free. Check the label on any brand, because some sell a “quick” steel cut oat right next to the traditional one.
Pumpkin puree
Use plain canned pumpkin, not pumpkin pie filling, which already has sugar and spices in it. A 15-ounce can of Libby’s 100% Pure Pumpkin holds about 1¾ cups, so you’ll have a little left over.
Milk
Any milk works here, including dairy, oat or almond. Milk is what makes the oats creamy instead of just soft.
Water
Water stretches the liquid so the oatmeal cooks evenly without getting heavy or scorching the way an all-milk batch can.
Maple syrup
Pure maple syrup sweetens the oats and adds the warm, caramel-like flavor pumpkin pie needs. Butternut Mountain Farm Grade A Amber maple syrup is a good everyday bottle. Pancake syrup won’t taste the same here.
Pumpkin pie spice
Pumpkin pie spice is a ready-made blend of cinnamon, ginger, nutmeg and allspice. McCormick Pumpkin Pie Spice is the one most grocery stores carry.
Vanilla extract
One teaspoon rounds out the spices and makes the whole bowl taste more like dessert.
Salt
A quarter teaspoon keeps the oatmeal from tasting flat, so don’t skip it.
How To Make Slow Cooker Pumpkin Steel Cut Oats
Step 1: Grease the slow cooker
Coat the inside of the crock with cooking spray or a thin layer of butter, especially around the sides where the oatmeal line will sit. For no-scrub cleanup, use a Reynolds slow cooker liner instead.
Step 2: Add everything to the crock
Add the steel cut oats, pumpkin puree, milk, water, maple syrup, pumpkin pie spice, vanilla and salt.
Step 3: Stir until smooth
Whisk until the pumpkin is fully mixed into the liquid with no streaks or clumps. Pumpkin left in a clump on the bottom is more likely to stick.
Step 4: Cook on LOW for 6 to 7 hours
Cover and cook on LOW until the oats are tender and creamy. If your slow cooker is programmable, set it for 7 hours and let it switch to warm.
Step 5: Stir and serve
The top may look a little separated when you lift the lid, and one good stir brings it back together. Add a splash of milk if it’s thicker than you like, then spoon into bowls and add your toppings.
Tips For the Perfect Slow Cooker Pumpkin Oatmeal
Cook on LOW, not HIGH
HIGH heat cooks the edges well before the center is ready. Steel cut oats on HIGH take about 3 to 4 hours and need stirring, so it isn’t an overnight method.
Learn your slow cooker on the first batch
Slow cookers vary a lot, even between models from the same brand. If yours runs hot, check the oats at 6 hours the first time and note what you find for next time.
[TEST NOTE — add after testing: what went wrong or almost went wrong on your first batch, and what you changed.]
Expect it to thicken
The oatmeal keeps thickening as it cools, so a texture that looks slightly loose in the crock is right. Thick and creamy with a little chew is the goal.
Add protein after cooking, not before
Each serving has about 10 grams of protein on its own. For more, stir a scoop of vanilla protein powder or a spoonful of Greek yogurt into your bowl after it’s served, since protein powder can turn gritty over a long cook. If you need a powder, here’s why Orgain is the one I buy at Costco, and these Greek yogurt bowl ideas have more ways to use the yogurt.
Top it like pie
This oatmeal is good plain, but toppings are what make it taste like an actual slice of pumpkin pie. Try any of these:
- Chopped pecans or walnuts
- A drizzle of maple syrup
- A sprinkle of cinnamon
- Pumpkin seeds
- Sliced banana or diced apple
- A spoonful of almond or peanut butter
- Greek yogurt
- A splash of milk or cream
Chopped pecans with a small drizzle of maple syrup is the combination that tastes most like pie.
Storage + Freezing
How to store pumpkin steel cut oats
Let the oatmeal cool, then refrigerate it in an airtight container for up to 4 days. For grab-and-reheat breakfasts, divide it into single servings in Pyrex Simply Store 2-cup glass containers and reheat right in the glass. If you’re prepping breakfasts for the week, a batch of Starbucks copycat egg bites gives you a savory option to rotate with this one.
How to freeze it
Freeze single portions for up to 3 months. Thaw overnight in the fridge, or microwave from frozen with a splash of milk, stirring every minute until hot.
[TEST NOTE — add after testing: how the oatmeal held up after freezing and thawing.]
How to reheat steel cut oatmeal
Refrigerated steel cut oats get much thicker overnight, so add milk every time you reheat.
- Microwave: Add one serving to a microwave-safe bowl with 2 to 3 tablespoons of milk. Microwave for 1 minute, stir, then heat in 30-second bursts until hot.
- Stovetop: Warm a larger portion over low heat with a splash of milk or water, stirring until it’s creamy again.
[TEST NOTE — add after testing: how much milk a refrigerated serving needed to get back to creamy.]
FAQs
Can I cook steel cut oats overnight in a slow cooker?
Yes. Cook them on LOW for 6 to 7 hours in a 3- to 4-quart slow cooker, ideally one that switches to warm when the timer ends. If the oats will sit longer than that, add an extra ½ cup of water.
Can I make overnight pumpkin steel cut oats without cooking them?
You can soak steel cut oats overnight in the fridge, but they stay quite chewy because they’re cut, not rolled. For a cold, no-cook version, rolled oats work better. This slow cooker recipe is the warm way to wake up to oatmeal that’s already made.
Can I use rolled oats instead?
Not in this recipe. Rolled oats break down into mush over a 6- to 7-hour cook. Make rolled-oat pumpkin oatmeal on the stovetop instead.
Can I use pumpkin pie filling instead of pumpkin puree?
Not as a direct swap, since pie filling already contains sugar and spices. If it’s all you have, leave out the maple syrup and pumpkin pie spice, then taste and adjust at the end.
Can I use fresh pumpkin?
Yes, as long as the puree is thick, like canned pumpkin. Watery homemade puree changes the texture, so drain it in a fine-mesh strainer first.
Can I make this crockpot pumpkin oatmeal on HIGH?
Yes. Cook it on HIGH for about 3 to 4 hours, stirring once or twice. Save this for a weekend morning, because HIGH isn’t safe to leave overnight without the edges burning.
Can I make it dairy-free?
Yes. Use oat or almond milk, and grease the crock with coconut oil or cooking spray instead of butter.
Is it gluten-free?
Oats are naturally gluten-free but are often processed alongside wheat. Use certified gluten-free steel cut oats if you need the recipe to be gluten-free.
Can I double the recipe?
Yes. Double everything and use a 6-quart slow cooker so the layer stays deep enough to cook evenly. Start checking at 7 hours.
Is pumpkin oatmeal healthy?
These pumpkin pie steel cut oats are a solid everyday breakfast, with about 275 calories, 6 grams of fiber and 10 grams of protein per serving, plus vitamin A from the pumpkin. For more breakfasts in the same spirit, try these anti-inflammatory breakfasts that don’t feel like health food.
