EATING BREAKFAST IS IMPORTANT

Having family dinner time has always been important in our house, and most nights we eat dinner as a family. But breakfast is a meal that we rarely eat together unless we are having breakfast for dinner. 😉

Many people skip the morning meal because they’re rushing to get out the door. But that’s a mistake.

Breakfast is the most important meal of the day, do you know why?

  • Energy and Concentration: People who eat a nutritious breakfast with protein do better in school and at work.  They won’t get hungry before lunch, and the protein will keep them from getting sleepy, cranky or even headaches.
  • Burn Calories: Breakfast kick-starts your metabolism, helping you burn calories throughout the day. 
  • Good Health: Studies show eating breakfast leads to good health like lower levels of “bad” LDL cholesterol, and lower chances of getting diabetes, heart disease, and being overweight.

Having something quick and delicious around for breakfast, like Baked Peanut Butter Oatmeal is a great way to make sure everyone fuels up for the day. Baked oatmeal is both nutritious and deeply satisfying and a much better alternative to cold sugary cereal.

HOW TO MAKE BAKED PEANUT BUTTER OATMEAL

(full printable recipe at the end of this post)

Making baked oatmeal is as simple as can be, it’s also a great make-ahead meal.  Make this simple baked peanut butter oatmeal on the weekend and have a delicious, healthy breakfast to enjoy all week long. You can eat it cold or heat it in the microwave just a bit.

We like to separate the baked oatmeal into single servings and place each cooled serving into its own airtight container in the refrigerator. This way you can have a grab and go breakfast ready every morning for the whole workweek. 

Start by preheating the oven to 350°F, and grease a large baking dish. Then, using a large bowl, mix all of the oatmeal ingredients until well combined. Next, transfer the oatmeal to the prepared baking dish and bake in the oven until edges are golden brown. A knife inserted in the center will come out mostly clean with a few wet crumbs. 
Serve with warm milk poured over the top and a drizzle of peanut butter if desired.

TIPS FOR MAKING THE BEST BAKED PEANUT BUTTER OATMEAL

  • Be sure to use rolled or old-fashioned oats for the best results when making this peanut butter oatmeal. Quick oats will work in a bind, but will not hold the texture and can become mushy, steel-cut oats will come out crunchy.
  • DON’T overbake the oatmeal! Even if it doesn’t look quite done at first, it will continue to bake in the pan even after you take it out of the oven. 
  • Wait to dig in. Allow the baked oatmeal cool for 10 minutes before serving.
  • If you like a crunch in your oatmeal try adding some chopped pecans, peanuts or walnuts.

Baked Peanut Butter Variations

While this oatmeal is delicious with just a little milk poured over the top, make it your own with delicious toppings.

  • slice bananas on top sprinkle a little cinnamon then pour warm milk
  • sprinkle with a few mini chocolate chips and or pecans
  • add yogurt and a little maple syrup

HOW TO STORE PEANUT BUTTER BAKED OATMEAL

You can keep leftover baked oatmeal in the refrigerator for up to a week. Just reheat it when you’re ready to enjoy!

To Freeze: Allow the oatmeal to cool completely.  Store individual servings of the oatmeal in airtight freezer bags or containers. Reheat in the microwave with a tablespoon of water.

Glass Bowl Set

Everyone should have a good set of mixing bowls in their kitchen. This set is my favorite because the variety of sizes means I always have exactly what I need available. 

Oblong Casserole Dish:  

Sometimes I want to switch things up from just a normal square or rectangle casserole dish, and this oblong one does just the trick! 

Homemade Vanilla:  

With the prices vanilla skyrocketing, I like to make my own vanilla, because it’s so easy and just as good!
