Homemade Instant Oatmeal with Brown Sugar, Chia and Flax

For years, this has been our family's go-to breakfast. Because we customize individual servings to our liking, we each always claim one to be our favorite. It's warm, healthy and so easy, and gets even the most hectic mornings off on the right foot. Chia seeds and flax are not just healthy additions, but add great flavor and texture. Recipe makes 20 servings (enough for a week of breakfasts for a family of four), but can be doubled, tripled, quadrupled!

Oatmeal Base:

  • 10 cups / 32oz / 900g Rolled Oats (use gluten-free if needed, see note)
  • 1 cup / 7oz / 200g packed Brown Sugar
  • 1/2 cup / 3oz / 82g Chia Seeds
  • 1/3 cup / 3 oz / 84g Ground Flax Seeds (sub double the amount if using whole flax seeds)

Add-Ins (pick and choose your faves):

  • 1 cup Dried Fruit (goji berries, cranberries, blueberries, raisins, chopped apricots, chopped dates, mango, freeze-dried apples / bananas / strawberries)
  • 1 cup Nuts (pecans, walnuts, slivered almonds, chopped hazelnuts)
  • 1/2 cup Extras (toasted coconut, cacao nibs, chocolate chips)
  • 1 Tbsp Flavoring (powdered peanut butter, cinnamon, ground ginger, cocoa powder)


  • Put oats in the bowl of a food processor and pulse about 10 times, until most of the oats are chopped to roughly half their original size. (Adjust this to your preference - if you prefer a more creamy oatmeal, pulse more; we like some of the oats to be in larger pieces.)
  • In a large mixing bowl (do this in batches if it won't easily fit), combine the oats, brown sugar, chia seeds, and ground flax. Toss with your hands until everything is evenly mixed, breaking apart the brown sugar as you go.
  • If preparing individual servings, place a heaping half cup of oatmeal base into mason jars or plastic bags. Top each serving with add-ins of choice.
  • If preparing one large batch, combine oatmeal base with any combination of add-ins in the amounts listed and toss. When ready to serve, place a heaping 1/2 cup of oatmeal in a bowl.
  • To serve, add 1/2 cup very hot water or milk to the oatmeal and stir until smooth. Enjoy!!!


1) If you prefer not to use a food processor, substitute equal parts rolled oats and quick cook oats.
2) For added flavor and less of a raw taste to the oats, lightly toast the oats at 350 F for 10 to 15 minutes, stirring halfway through cooking. (Thanks so much to reader Cindy who sent this great tip!)
