Ingredients for Crockpot Blueberry Oatmeal
Making overnight oatmeal requires just a few simple ingredients you likely have in your pantry.
Milk - or substitute any non-dairy alternative like almond milk or coconut milk
Uncooked steel-cut oats - we also make this with old-fashioned oats with good results.
Blueberries - fresh or frozen blueberries.
Brown sugar - or substitute maple syrup or other desired sweetener
Butter - cut into 5-6 pieces (optional)
Ground Cinnamon - just a hint
Vanilla Extract - to give it that fresh-baked flavor

Oatmeal Topping Ideas
Optional oatmeal garnishes: chopped nuts, shredded coconut, bananas, maple syrup, additional milk, or additional blueberries and butter.
You'll also need a non-stick spray or a crockpot liner to prevent sticking.
HOW LONG TO COOK OATMEAL IN THE CROCKPOT
This crockpot oatmeal recipe is somewhat forgiving, but cooking your crockpot oatmeal for 7 hours with steel-cut oats is optimal, so it doesn't turn too mushy.
How To Make Step By Step Instructions
Grab your ingredients, and let's make this recipe. It takes under 5-minutes to put it all in your slow-cooker.
Step 1 - PREP CROCK POT
Coat the inside of your slow cooker with cooking spray or line it with a crockpot liner.
Step 2 - ADD INGREDIENTS

Recipe tips & tricks

- If you decrease the cooking time, you can use old-fashioned oats in this recipe.
- We use a 6-quart slow cooker for the recipe.
- All slow cookers cook differently, so the suggested cooking time is a basic guideline and should always be tested first in your slow cooker and adjust the time as needed.
How to store
- Store any leftover blueberry oatmeal in an airtight container in the refrigerator for 1-2 days.
- To reheat single servings: Put 1-cup cooked oatmeal in a microwave-proof bowl. Add ⅓ cup fat-free milk or milk alternative. Microwave on high for 1 minute; stir. Continue cooking for another minute or until hot.

That's awesome, Paige! So glad you enjoyed this easy oatmeal as much as we do!
Wonder if this would work well doing the water bath technique and if that would affect cooking times or not. That is what I am going to try tonight since I have some blueberries I was trying to decide what to do with.
Erin Henry says
Hi Allison, we haven't tried the recipe with a water bath, but It would likely work. As for cooking time, I'm not sure if it would affect that or not. If you try it out, let us know how it goes!
It works out well, I use a water bath just cause several other steel cut oat recipes do to prevent it getting all crusty along the upper edge especially if it sits on warm for a bit after finishing cooking. It turns out great! I ended up substituting ground ginger for the vanilla (cause I had run out) and it was great! About 0.5 tsp this time.
This oatmeal has zero flavor idk why everyone says it’s so tasty. Very bland and no taste at all
Erin Henry says
Sorry to hear that, Ryan. We've always enjoyed the flavor. You can always add more flavor by using fresh ground cinnamon and increasing the brown sugar and vanilla. Also, make sure your blueberries are nice and ripe.
Jan Brackman says
Delicious recipe! Making it for the second time tonight and substituting cherries for blueberries!
Erin Henry says
OMG! Cherries will be so good. We love it when they're in season. Enjoy your next crock of yumminess!
Oh I will have to try that, I have some I froze from a previous season (nice sour pie cherries)!
This was very good. I will keep a close eye on the cooking time as it was burning to the sides of my crock pot at 4 hours, and it was set on "low". The end result was still very tasty! Thank you for the recipe!
Erin Henry says
Yes, each crockpot cooks a little differently, Dee. If you find yours is cooking on the hot side, you can also use the warm setting.
The oatmeal was soooo good I made them a 2nd time. I set crock pot on low for 3 hours and they came out perfect! You are correct...my crock pot definitely cooks on the hot side. Thank you for your response! And thanks again for this delicious recipe!
