Let’s Back Up

What did that say? Oatmeal, Slow-cooker, Freezer? Let’s back up here for a minute. First off you did read that right, recipes for making steel cut oats  in the slow cooker have been around for sometime now, with good reason. Steel-cut oats are made easy in a slow cooker. Everything is tossed into the slow cooker, turn it on high and in a few hours, you have oatmeal. If you have ever searched for recipes for oatmeal made in the slow cooker, you’ll find a ton.

Try Some Oatmeal

Personally I like oatmeal, always have. I like steel-cut oatmeal, also know as Irish oatmeal, even more. When slow cooker oatmeal started to appear everywhere, I was thrilled. It’s a great way to add some variety to your breakfast and extra fiber, if your into that sort of thing. Even my grandson loves slow cooker oats. What I don’t like about slow cooker oats, is that most recipes I’ve tried, (it seems to me anyway) that the cooking times are off.

What I Mean By That

What exactly do I mean by that? Some recipes call for cooking the oats overnight in the slow cooker and I have done that. In the morning I’ve woken up to a burnt mess. Other recipes say to cook the oats overnight or for 4 to 6 hours on low?? I’ve often wondered, “What time to these people go to bed?” From reading the directions, they certainly don’t need much sleep! I get up every morning at 7:00 am to let the dogs out, so that would mean?

So that would mean that I would have to make and start my slow cooker overnight steel-cut oats at 1:00 am? I don’t think so. That’s what I mean by ‘the cooking times’ are off. Don’t get me wrong, I myself have recipes on Turnips 2 Tangerines that have the same directions, which I might add, I’m going to change right after I write this post. So how can we solve this culinary dilemma? Easy! Freeze It!!

Freezer Friendly

After your oatmeal has cooked on high for 4 to 6 hours, allow oatmeal to cool.  Spoon cooled oatmeal into jumbo muffin tins (1 cup size) that have been sprayed with a non-stick cooking spray, freeze overnight or until firm. Remove the frozen oatmeal muffin tin from freezer. Allow to sit at room temperature until oatmeal ‘muffins’ can be removed from tin. Use a butter knife to carefully pry ‘muffins’ out of tin. Divide oatmeal ‘muffins’ into six individual zip lock freezer baggies and return to freezer until ready to serve.

To Serve

When your ready to serve your freezer steel-cut oatmeal, simply place one freezer oatmeal ‘muffin’ into a microwave-safe cereal bowl. Heating directions will vary from microwave to microwave depending on wattage. My microwave is only 700 watts. The directions I give will be for a 700 watt microwave. Heat on defrost for one minute, add a small amount of milk or coffee creamer. Heat for another minute or two on high. Serve with candied pineapple, chia seeds and drizzle with honey.

Busy Mornings

Now your busy mornings will be filled with a ‘good for you’ warm bowl of ‘made ahead’ slow cooker steel cut oatmeal. Breakfast option: Slow Cooker Apple Fritter French Toast Bake
