Easiest Baby Oatmeal (and Best Ways to Flavor It)

Make healthy baby oatmeal at home in less than 5 minutes and learn how to add flavor and nutrition easily with this super simple method. This is a great baby food that can change and evolve with baby. It’s nutritious, affordable, and often tastier than store-bought baby cereal!

Baby Oatmeal

Oatmeal has been a staple in our house even before I had kids, and I was so glad to learn that turning it into a version of baby oatmeal is crazy easy. Yes, you can buy baby oatmeal, but I find that it usually smells (and tastes) a little funny, and it can be expensive.

This version of baby oatmeal, which is so easy to make and actually tastes like oatmeal, is a great baby food option. My kids loved this when they were new eaters!

I love this as a nutritious, whole grain breakfast. And it’s a quick meal for any other time of day. It’s almost as fast to make as baby cereal from the store but has a much better flavor. It’s easy to make the base to keep on hand in the pantry, then mix it up whenever baby is ready for a quick meal.

Ingredients You Need

To make this recipe, you’ll need to have the following ingredients on hand and ready to go.

• Old-fashioned rolled oats: This form of oatmeal is easy to find at the store and keep on hand in the pantry. You can choose organic oatmeal if you prefer. You can also start with instant oats or even steel-cut oats if you have a high-powered blender to grind them up.
• Liquid: Such as water, breastmilk, formula, or unsweetened nondairy milk.
• Spices: Cinnamon, cardamom, or other warm spices can be added, optionally, for more flavor.
• Puree: You can add a fruit or veggie puree, or mashed fruit such as banana, to flavor to the oatmeal.
• Other add-ins: You can mix in other add-ins for flavor, nutrition, or allergen exposures such as nut butter, chia seeds, hemp seeds, or flaxseeds.

Step-by-Step Instructions

Here’s a look at the easy process of making this DIY baby cereal recipe. Scroll down to the bottom of the post for the full information, including the amounts and timing.

1. Add the oats to a blender. Grind, starting on low and working up to high, until the oats form a fine powder-like flour, which is the base of the oatmeal cereal.
2. Add some ground-up oats to a heat-safe bowl.
3. Add a little hot water and stir. Add more to thin to desired consistency depending on baby—thinner for newer eaters and a little thicker as they become more comfortable with texture.
4. Stir in optional flavorings and nutrients.

TIP: You can start off making this thinner as a Stage 1 baby food, then gradually add less water to make a thicker Stage 2 baby food.

Serving Suggestions

You can offer a small amount on a spoon, then stop offering it when baby closes their mouth or turns their head, as those are signs baby is done. Or you can put a little on a spoon and hand the spoon to baby to feed themself.

Baby Cereal for Baby-Led Weaning

You can serve this to a baby, whether you’re starting with purees or doing the baby-led weaning style of feeding. With the latter, simply put some of the cereal onto a spoon and hand the spoon to baby to self-feed. Repeat the process until baby shows signs of being done, such as turning her head or closing her mouth to the spoon.

(My favorite baby and toddler spoons can help with making sure this method is easy, too.)

Optional Flavorings to Add to Baby Oatmeal

Here are some ideas for what you can stir into baby oatmeal to make it more flavorful and nutritious for baby. Babies need healthy fats and iron, and to be exposed to a range of flavors, so these are some great options to work into the mix.

Add about 1-2 tablespoons of each puree and 1/2-1 teaspoon of the flaxseed to each serving of oatmeal.

TIP: Store-bought baby cereal is typically fortified with iron, so if you want that option, consider checking with your pediatrician about adding some infant iron supplement to the finished oatmeal. Or, add iron-rich foods into baby’s daily meal schedule.

Best Store-Bought Baby Oatmeal

I love the Amara Organics Oats n’ Berries (paid affiliate link). It has a delicious berry flavor and 50% less sugar than other similar products, and it mixes up so fast that it’s a nice option to have on hand for fast meals for baby.

How to Store Leftover Baby Oatmeal

To store any leftovers, simply place into a small baby food storage container and store in the fridge for up to 3 days. Add a little hot water to thin out (it will thicken in the fridge) and serve.

Best Tips for Success

• Store leftovers in a small airtight container for up to 3 days in the fridge. Thin and warm with hot water to serve.
• You can use breastmilk or formula instead of the water if you prefer. As baby grows, you can use plain unsweetened nondairy milk, then cow’s milk over age 1.
• Add more liquid to thin to desired consistency depending on baby—thinner for newer eaters and a little thicker as they become more comfortable with texture.
• To make organic baby oatmeal, start with certified organic rolled oats.
• To make gluten-free baby oatmeal, start with gluten-free rolled oats.
• To make different grains like rice, millet, and quinoa into baby cereal, grind in a high-powered blender—I love my refurbished Vitamix—and add liquid as directed in this recipe.
• I have multigrain baby cereal recipes for Quinoa Baby Cereal and Baby Rice Cereal that you may enjoy.

• Add the oats to a blender. Secure the lid and grind, starting on low and working up to high, until the oats form a flour-like powder.

• Add 1 tablespoon of the oat powder to a heat-safe bowl. Stir in about 2 tablespoons very hot water (or warm breastmilk or formula), adding more as needed to thin to desired consistency. (Start thinner, so the mixture is easy for baby to move around in their mouths—it should not be sticky for new eaters. You can gradually use less liquid as baby becomes more comfortable with solids.)

• Add any optional flavorings. Serve with a spoon or offer a preloaded spoon to baby to feed themself, stopping the meal when they turn their head or close their mouth.

• Store the remaining ground-up oats in an airtight container.

• Store leftovers in a small airtight container for up to 3 days in the fridge. Thin and warm with hot water to serve. Store any dry oatmeal in an airtight container in the pantry for up to 6 months.
