It is always my goal to make a hot breakfast 4 days per week. There’s something about waking to a hot breakfast that makes the day instantly feel special. I don’t always have the time or energy to prepare a big breakfast in the morning, nor do I always want to deal with a dirty kitchen upon waking, so having a few recipes that can be prepped the night before is so nice. This simple overnight oatmeal bake is perfect for that and a recipe that all of my kids love!

Not only is this great for weekly breakfasts, but it’s also a great recipe to keep in your recipe box for when you have company staying with you. I make this oatmeal bake and an egg casserole (both made the night before) every time we have overnight guests. All that is required the morning of is that I pop them in the oven. 🙂

What is Overnight Oatmeal Bake?

This dish is a simple oatmeal bake that you can make the night before and it chills in the refrigerator. The soaking of the oats overnight helps to break down the starch so it’s more digestible. This is the hot version of regular overnight oats, which you eat cold in the morning.

An overnight oatmeal bake has eggs in it that create an oatmeal that holds together. This recipe is completely adaptable to your family’s personal needs. I even love changing it up for my family!

Ingredients for a Baked Oats Recipe

All of these ingredients are regular pantry items. If I’m in a pinch as I’m preparing for breakfast the next day and I don’t have many groceries, this is the dish I make.

  • Eggs– Eggs are what hold this baked oats recipe together. Without them, it would be crumbly, but still yummy!
  • Maple Syrup– The maple syrup is what sweetens this dish and it has adds a nice underbelly to the flavor profile on this baked oats recipe. You may also use regular sugar, brown sugar, or honey!
  • Baking powder– Baking powder helps to create a bit of a rise to the casserole so it will be light and fluffy.
  • Vanilla– This is the secret ingredient in so many baked goods because you can’t really taste it, yet it adds so much depth of flavor.
  • Cinnamon– A hint of spice is nice in every dish and this one gets it from cinnamon.
  • Butter– Every good dish has butter in it, doesn’t it? You may substitute your preferred oil for this, but the butter has a creamy flavor that other oils don’t match.
  • Apple Sauce– Apple sauce sometimes takes the place of fats in baking, but here, it just adds a mild, apple flavor and helps to break down the gluten in the oats as they soak.
  • Milk– Breaking down the starch is a major digestion benefit for this baked oats recipe and the milk is the main ingredient that the oats soak in for this to happen.
  • Old-fashioned oats– Feel free to use whatever oats you prefer, but the larger, old-fashion variety work best for this as they have some structure to them and they hold up with overnight soaking. Plus, their nutrition profile is better than other oats!

Simple Adaptations for Overnight Oatmeal

One of the things I love about this recipe is how easy it is to adapt it to your needs. This is a wonderful base recipe that allows you a lot of wiggle room to make it your own! We have done several different adaptations to this simple overnight oatmeal bake. Let me share a few that we love:

  • Add a crumble– 1 cup oats + 1/2 cup flour + 1/2 cup brown sugar + 1/2 cup melted butter or coconut oil Stir crumble toppings together and spread evenly on top of the oatmeal bake prior to baking.
  • Cinnamon-Apple Oatmeal– Shred one apple and add to the oatmeal bake.
  • Add Blueberries– Adding in a cup of fresh or frozen blueberries is an easy variation.
  • Try a glaze– Mix 1 cup powdered sugar and 4-5 tablespoons of milk together and drizzle on the bake.
  • Add shredded coconut– Coconut is an easy add in. Add 1/2 cup coconut to give this bake a bit of chew.
  • Cinnamon-Sugar Oatmeal– My kids love when I sprinkle this oatmeal bake with cinnamon and sugar topping.
  • Nuts– Nuts add a bit of texture to the oatmeal bake that is delicious. You can use walnuts or pecans, which I find taste the best in this dish.

Tips and Tricks for Baked Oats

  • Not enough eggs? This baked oats recipe calls for two eggs. If you want to double it and don’t have quite enough, don’t worry! Use what you have. It will still be delicious, but it might be a bit crumbly, which kids don’t usually mind.
  • You may substitute any milk for regular milk in this recipe. You can even use oat milk!
  • After baking, you may reheat them to eat for another day. Put the baked oats in the fridge and warm up in a 200°F oven for 20 minutes. Be sure to sprinkle some water over the bake to keep it moist and cover it with aluminum foil so it doesn’t dry out.
  • This is a great baked oats recipe to eat with heavy cream or milk on the second day. If your kids are wanting something different, but you still have some overnight oatmeal bake left, put it in bowls with fresh fruit, a drizzle of maple syrup, and a splash of heavy cream to give them a different version of the same meal!

    I just baked this and it is delicious! I did the crumble topping and apple add-in. For those that might be wondering, it turned out perfectly using oat milk and coconut oil since I needed to avoid the dairy. I highly recommend this recipe to anyone looking for an easy breakfast recipe!

    1. It is best to let it sit for several hours or overnight so the oats can soak up the milk. I’m afraid it would be very runny if you didn’t. If you try it, let me know if it works!
