Overnight Steel Cut Oatmeal This breakfast is one of my favorites! Similar to overnight oats there is virtually no morning prep required. A healthful, warm, creamy, sweet, and comforting breakfast awaits you the minute you’re ready to begin the day. It’s simple, with minimal prep required — it takes about 10 minutes (or less) to throw everything together. The only tricky component for figuring out this recipe was how to allow it to cook in the slow cooker without getting overly mushy. It’s perfect after about 3 hours, but that’s really only beneficial for a brunch. So after loads of testing, I’m excited to share how you can have this oatmeal piping hot, not at all mushy, loaded with flavor, AND ready after a good 7-8 hours of sleeping time. Steel cut oats Why use steel cut oats? For one, they are the only oats I’ve found to work overnight in the slow cooker. Rolled oats or quick oats end up overly mushy and absorb too much of the liquid. Here are a few other reasons why it’s great to add steel cut oats into your diet: Because steel-cut oats are minimally processed, they contain more fiber and density and are one of the most nutritious grains you can eat. As a complex carbohydrate, steel cut oats are a great way to give your body a energy to last through the day. (Complex carbs are harder for the body to break down and use so it takes longer while providing a more sustained energy source.) Steel cut oats are denser than other oats meaning you can eat less of them, feel satiated longer, and all while still gaining the same nutritional benefits found in rolled oats. Steel cut oats contain 7g of protein in every 1/4 cup of dry oats. Quinoa I love the textural add of combining quinoa with steel cut oats in this breakfast! Quinoa is full of fiber, protein, vitamins, and minerals. It is also a great source of protein with 8 grams of protein per 1 cup of dry quinoa. Quinoa has a natural coating called saponin which can make it taste bitter. Make sure to first rinse the quinoa in a fine mesh strainer and wash thoroughly for 30 seconds to one minute to remove that coating. I don’t recommend any substitutes for the quinoa; it absorbs the liquid and really thickens up these oats. It also adds a deep savory, almost nutty, flavor to this overnight steel cut oatmeal. Overnight Steel Cut Oatmeal tips Use a 6-quart slow cooker. I have tested this recipe multiple times in 6 quart slow cookers, but have not personally tested in smaller slow cookers so I can’t vouch for how they will work. Generously grease or line the slow cooker. This overnight steel cut oatmeal can be messy to clean-up without a prepared (greased or lined) slow cooker. Do not remove the lid. As tempting as it may be to check on the oats after they’ve cooked on low for 30 minutes, do not remove the lid! This allows all for the heat to escape and the dish won’t properly cook in time. Make sure to use steel cut oats not rolled oats or quick oats. I haven’t had success with cooking any other types of oats overnight in the slow cooker. We love almond milk in these oats. While you can use water in a pinch, the almond milk gives these oats a phenomenal flavor and creaminess. Do not use cows milk in place of the almond milk, it will curdle overnight. Don’t forget the toppings! More on this below. Toppings Don’t get me wrong, this overnight steel cut oatmeal is luscious, creamy, and perfectly sweet, but it does rely on some great toppings! Hands-down our favorite additions to these steel cut overnight oatmeal are these “off-beat” nut butters. I’m not sponsored or affiliated by this company, but I’ve included the links below to order online. While a bit spendy, they are the best nut butters I’ve ever tried! Here are our favorite topping combos: Banana: extra cinnamon, thinly sliced banana, a big scoop of cinnamon bun nut butter, almond butter, or peanut butter, & a splash of milk Berry: a handful of frozen raspberries mixed into the oats and topped with fresh strawberries, fresh raspberries, and/or any other berries with a splash of milk and a spoonful of almond butter or aloha nut butter. Apple: extra cinnamon, diced honey-crisp or fuji apple, big scoop of cinnamon bun nut butter, almond butter, or peanut butter, & a splash of milk Strawberries & Cream: diced up strawberries, splash of milk or coffee creamer, and lemon coconut bliss butter or almond butter Nuts & Seeds: handful of toasted and coarsely chopped nuts (sliced almonds, pistachios, pecans, walnuts, etc), small handful of sunflower or pumpkin seeds, small handful of dried cranberries, dried blueberries, raisins, or dried tart cherries, and a big scoop of almond or peanut butter Additional sweetener: depending on how sweet you like your breakfast and what toppings have been added, you may want to add an extra drizzle of honey, maple syrup, or a sprinkle of brown sugar to top the oats. Liquid stevia is another great option for a zero calorie sweetener. Overnight Steel Cut Oatmeal Cooking Options For morning brunch: cook on low for 2-1/2 to 4 hours. I don’t recommend cooking these overnight steel cut oats on high temperature Overnight – with quick cooking steel cut oats: cook on low for 30 minutes and then turn to warm for 6-7 hours Overnight – with regular steel cu oats: cook on low for 1 hour and then turn to warm for 8-9 hours Note that not all slow cookers are the same, some cook at a higher temperature than others. If your slow cooker has a tendency to cook quicker, it may be done even sooner than the times indicated.

Course Breakfast Cuisine American Keyword Overnight oats and quinoa Prep Time 15 minutes Cook Time 8 hours Total Time 8 hours 15 minutes Servings 6 Calories 131kcal Cost $3.23 Ingredients1 and 1/2 cups (215g) steel cut oatmeal (See Note 1)1/2 cup (90g) white quinoa5 cups (1265) unsweetened vanilla almond milk (or water; we prefer almond milk!)4 tablespoons (50g) brown sugar2 tablespoons real maple syrup1/4 teaspoon salt1 and 1/2 teaspoons vanilla extractOptional: 1/4 teaspoon ground cinnamon, fresh berries, splash of milk, additional sugar for topping InstructionsPREP: Spray your slow cooker generously with non-stick spray or line with a slow cooker liner. In a mesh strainer, rinse out the quinoa really well under cold water for about 30 seconds to 1 minute. Let dry.FILL UP SLOW COOKER: Combine the steel cut outs, rinsed quinoa, almond milk, brown sugar, maple syrup, salt, vanilla extract, and cinnamon (if desired) into the slow cooker.COOK OVERNIGHT: Stir everything together really well, place the lid on the slow cooker, and then set your slow cooker to low for 1 hour. Then, without opening the slow cooker or disturbing it (otherwise the heat escapes!), switch the dial to "warm" setting. Allow to "cook" overnight for 8-9 hours (longer than that and it becomes mushy). See Note 2IN THE MORNING: Once you wake up, immediately turn it off the heat and stir the oats. They may still have some liquid, but it continues to soak in as they are served (we like them better with extra liquid rather than dry and mushy/gummy!) These oats are intended to be fairly creamy.SERVE: We have plenty of serving suggestions in the post, but add your favorite toppings such as fresh fruit, an extra splash of milk, any additional brown sugar, honey, or maple syrup, and a big scoop of nut butter (peanut butter, almond butter, etc.). Recipe NotesNote 1: do not use regular old fashioned or rolled oats or quick oats -- they won't work. IF you use instant or quick cooking steel cut oats (be sure to check the package, sometimes it's hard to tell if they are instant steel cut oats at first glance), it will be done in about 6-8 hours. For best results, I highly recommend regular steel cut oatmeal. Note 2: Different cooking options: For morning brunch: cook on low for 2-1/2 to 4 hours. (I don't recommend cooking these overnight steel cut oats on high temperature.) Overnight - with quick cooking steel cut oats: cook on low for 30 minutes and then turn to warm for 6-7 hours Overnight - with regular steel cut oats: cook on low for 1 hour and then turn to warm for 8-9 hours Note that not all slow cookers are the same, some cook at a higher temperature than others. If your slow cooker has a tendency to cook quicker, it may be done even sooner than the times indicated. If it is left in the slow cooker too long it will likely become mushy and gummy. If your slow cooker has a tendency to cook slower and oats/quinoa isn't tender, turn the slow cooker back on to low for 30 or so minutes in the morning.
