Easy Baby Oatmeal Recipe (6 Months+)
Oatmeal is one of the most familiar first foods in American kitchens, and it’s easy to make at home. This baby oatmeal recipe uses just two ingredients, plain rolled oats and water, and takes under 20 minutes from start to finish. You grind the oats first, so the cooked cereal turns out smooth and creamy instead of chunky.
Below you’ll find step-by-step instructions, how to adjust the texture as your baby grows, safe mix-in ideas, and clear storage and reheating guidance.

Why Make Homemade Baby Oatmeal?
- Two simple ingredients. Plain oats and water, with no added sugar or salt.
- Budget-friendly. One canister of rolled oats makes many batches.
- Easy to customize. You control the thickness, so the same recipe works from first tastes through older-baby textures.
- Freezer-friendly. Make a batch once and portion it for later in the week.
- A base for new foods. Once your baby has tried a few single foods, oatmeal pairs well with fruit and vegetable purees.
Easy Baby Oatmeal
Ingredients
Method
- Grind the rolled oats in a blender, food processor, or clean spice grinder for 30-60 seconds, until they look like fine flour.
- Bring 1 1/2 cups (360 ml) water to a boil in a small saucepan over medium-high heat.
- Reduce the heat to low. Slowly sprinkle in the ground oats while whisking constantly.
- Simmer for 5-7 minutes, whisking often, until thick, creamy, and fully cooked. Add 1-2 tablespoons water if it becomes too thick.
- For new eaters, blend the cooked oatmeal until very smooth. Cool slightly first, fill a countertop blender no more than halfway, and vent the lid.
- Spoon one serving into a separate bowl and cool to lukewarm, about 5 minutes.
- Stir in breast milk, formula, or water 1 teaspoon at a time until it reaches the desired texture.
- Stir well and check the temperature before serving. Refrigerate or freeze the remaining plain oatmeal within 2 hours.
Notes
Is Oatmeal Safe for a 6-Month-Old?
For most babies, yes. The American Academy of Pediatrics (AAP) and the CDC recommend starting complementary foods at about 6 months, based on your baby’s development, not age alone. Breast milk or formula remains your baby’s main source of nutrition throughout the first year.
Signs Your Baby May Be Ready for Solids
- Holds their head and neck steady
- Sits up with little or no support
- Opens their mouth when food comes near
- Shows interest in food, such as watching you eat or reaching for your plate
- Can move food from the front of the mouth to the back and swallow, rather than pushing it out with the tongue
Every baby develops at their own pace. If your baby was born early, has a medical condition, or has trouble swallowing, talk with your pediatrician before starting solids.
Homemade Oatmeal vs. Iron-Fortified Infant Oat Cereal
This is an important difference. Store-bought infant oat cereal is usually fortified with iron, a nutrient babies need more of starting around 6 months. Regular rolled oats contain some iron naturally, but much less than fortified infant cereal.
That doesn’t make homemade oatmeal a poor choice. It just means it shouldn’t be your baby’s only iron source. Offer iron-rich foods regularly, such as pureed meats, mashed beans or lentils, well-cooked egg, or iron-fortified infant cereal. If you prefer fortified cereal, follow the mixing directions on the package instead of this recipe. Ask your pediatrician if you have questions about your baby’s iron needs.
Ingredients You’ll Need
- Old-fashioned rolled oats: Plain and unsweetened. Avoid flavored instant packets, which often contain added sugar and salt. Choose oats labeled certified gluten-free if your family needs to avoid gluten.
- Water: For cooking the oats.
- Breast milk or prepared infant formula (optional): Stirred in after cooking to thin the oatmeal and give it a familiar flavor.
How to Make This Baby Oatmeal Recipe
- Grind the oats. Add 1/2 cup (about 40 g) rolled oats to a blender, food processor, or clean spice grinder. Blend for 30 to 60 seconds, until the oats look like fine flour with no visible flakes.
- Boil the water. Bring 1 1/2 cups (360 ml) water to a boil in a small saucepan over medium-high heat.
- Whisk in the oats. Turn the heat to low. Sprinkle in the ground oats slowly while whisking constantly to prevent lumps.
- Simmer. Cook on low for 5 to 7 minutes, whisking often, until the oatmeal is thick, creamy, and no longer tastes raw or gritty. If it gets too thick, whisk in 1 to 2 tablespoons more water.
- Blend if needed (optional). For new eaters, blend the cooked oatmeal for an ultra-smooth texture. If using a countertop blender, let it cool for a few minutes first, fill it no more than halfway, and vent the lid.
- Cool and thin. Spoon one serving into a separate bowl and let it cool to lukewarm. Stir in breast milk, formula, or water, 1 teaspoon at a time, until it reaches the right texture for your baby.
- Check the temperature. Stir well and test a small amount on the inside of your wrist. It should feel lukewarm, not hot.
- Store the rest. Refrigerate or freeze the remaining plain oatmeal within 2 hours of cooking.
Tip: Add breast milk or formula only to the portion you’re serving. Keeping the main batch plain makes storage simpler.
Baby Oatmeal Texture by Age
Textures should progress as your baby’s eating skills develop. These ages are general guides, not rules.
| Stage | Typical age | Texture | How to adjust |
|---|---|---|---|
| First tastes | Around 6 months | Thin and very smooth; drips easily off a spoon | Blend after cooking; thin generously |
| Building skills | About 7 to 8 months | Thicker and smooth; holds briefly on a tilted spoon | Use less liquid when thinning |
| More texture | About 8 to 10 months | Thick with soft, small bits | Grind the oats more coarsely or skip blending |
| Older babies | About 9 to 12 months | Soft cooked whole rolled oats | Cook unground rolled oats until very soft |
Gagging can be a normal part of learning new textures. Choking is different and is often silent. Always seat your baby upright and stay with them during meals.
How Much Baby Oatmeal to Serve
Start small, with 1 to 2 teaspoons once a day, and increase gradually. Many babies work up to 1 to 4 tablespoons per meal over the following weeks. Follow your baby’s cues: leaning in and opening their mouth usually means “more,” while turning away or closing their mouth means “all done.”
Offer oatmeal from a spoon only. Never put oatmeal or infant cereal in a bottle unless your pediatrician specifically directs it, because it can cause choking and overfeeding.
Allergen and Gluten Notes
- Oats are not one of the nine major food allergens in the United States.
- Gluten: Oats are naturally gluten-free, but regular oats are often processed alongside wheat. Choose certified gluten-free oats if your baby has a diagnosed reason to avoid gluten.
- Mix-ins can add allergens. Formula may contain milk or soy, and some suggested add-ins (yogurt, peanut, tree nut) are major allergens.
- Watch for reactions. Hives, swelling, vomiting, or trouble breathing after eating need urgent medical care. Call 911 for breathing trouble or swelling of the face or lips. Repeated vomiting a few hours after eating oats should also be checked by your pediatrician.
When introducing new foods, many families offer one new food at a time and wait a few days before the next. This makes it easier to spot a reaction.
Safe Mix-Ins and Variations
Once your baby has tried these foods on their own, you can stir them into prepared oatmeal:
- Fruit purees: unsweetened applesauce, pear puree, or mashed ripe banana
- Vegetable purees: pumpkin, butternut squash, or sweet potato
- Warm spices: a small pinch of ground cinnamon
- Dairy: a spoonful of plain, unsweetened whole-milk yogurt (contains milk)
- Peanut: a small amount of smooth peanut butter thinned with warm water, or peanut powder, stirred in completely (contains peanut). If your baby has severe eczema or an egg allergy, talk with your pediatrician before introducing peanut.
Don’t add: honey (not safe before 12 months, even cooked), maple syrup or sugar, salt, whole nuts, chunky nut butter, or whole raisins. Never serve spoonfuls of thick nut butter.
Storage, Freezing, and Reheating
- Refrigerator: Store plain cooked oatmeal in an airtight container for up to 3 days.
- Freezer: Spoon cooled oatmeal into a lidded silicone tray or small freezer-safe containers. Once frozen, transfer portions to a labeled freezer bag. Use within 1 month for best quality.
- Thawing: Thaw in the refrigerator overnight. Don’t thaw at room temperature or refreeze thawed oatmeal.
- Reheating: Warm on the stove or in the microwave, stirring well to remove hot spots. Oatmeal thickens as it sits, so add a little water to loosen it. Let it cool and test the temperature before serving.
- Breast milk: Don’t heat breast milk in the microwave. Stir it into oatmeal after reheating.
- Leftovers: Discard any oatmeal left in your baby’s bowl. Saliva from the spoon can let bacteria grow.
Common Mistakes to Avoid
- Skipping the grinding step. Whole flakes are too textured for most new eaters.
- Serving it too thick. A thick paste can be hard for beginners to manage. Thin it until it flows off the spoon.
- Adding sweeteners or salt. Babies don’t need them, and honey is unsafe before age 1.
- Serving it hot. Oats hold heat. Always stir and test before serving.
- Relying on homemade oatmeal for iron. Include other iron-rich foods each day.
- Feeding straight from the storage container. Portion what you need into a separate bowl first.
Baby Oatmeal FAQs
Can I use quick oats or steel-cut oats for baby oatmeal?
Quick oats work well. Grind them the same way, and they may cook a minute or two faster. Steel-cut oats are harder to grind finely and take much longer to soften, so rolled or quick oats are the easier choice.
Can I make baby oatmeal with breast milk or formula?
Yes. Cook the oats in water, then stir breast milk or prepared formula into the cooled serving. Prepare formula according to the package directions.
Can babies have oatmeal made with cow’s milk?
Cow’s milk shouldn’t be offered as a drink before 12 months. Cooking with water and thinning with breast milk or formula is the simplest option. Ask your pediatrician if you’d like to use cow’s milk in cooking.
Is homemade baby oatmeal iron-fortified?
No. Plain rolled oats contain some natural iron, but far less than iron-fortified infant cereal. Pair homemade oatmeal with other iron-rich foods.
Can I put oatmeal in my baby’s bottle?
No, unless your pediatrician tells you to for a specific medical reason. Cereal in a bottle can cause choking and overfeeding. Serve it from a spoon.
How often can my baby eat oatmeal?
Oatmeal can be a regular part of a varied diet. Offering a mix of grains, vegetables, fruits, and protein foods helps your baby experience new flavors and textures.
More Baby Food Recipes to Try
Once your baby enjoys oatmeal, try pairing it with simple single-ingredient purees, such as apple, pear, sweet potato, or butternut squash. (Editor: add links to published recipes; see Part 6.)
