5 ingredients are all you need to make this healthy, protein and fiber-rich instant pot multigrain rice. Barley, rice, quinoa, lentils, and beans make this hearty side dish a great way to add variety to your baby, child, and adult's diet!

Being Asian, rice is a pantry staple at our house. In fact, in Korea, which is where I was born, it's not uncommon for people to eat rice for breakfast, lunch, and dinner. There's even a saying that we live by rice power, "밥심으로 산다."
In many countries, rice is not just a food. It’s life. It’s deeply rooted in culture, economy, and environment in so many parts of the world! Where I'm from, a meal is not considered complete without rice.
Why am I saying all this?
Rice and Arsenic
As a registered dietitian specializing in baby and child nutrition, I'm very much aware of the fear surrounding arsenic in rice that many parents face.
According to a recent report, 95% of baby foods are contaminated with one or more toxic heavy metals. These include lead, arsenic, mercury, and cadmium. This is concerning as these toxins are neurotoxic and can negatively affect the growth of the baby's brain during this critical time of development.
No wonder parents are panicked and can't help but question every single piece of food they put into their little one's mouth! But keep reading because I'm here to help keep your sanity and confidence in feeding your child.
The Top Offenders
- rice-based cereals and snacks
- juices
- sweet potatoes
- carrots
The report also revealed that whether the food is store-bought, homemade, organic or conventional, they all contained heavy metals. That's because they are found in the food supply regardless and organic food standards don't cover these heavy metals.
Heavy metals are everywhere. They are found in the environment through pesticides, pollution but are also naturally found in air, soil, and water.
Ways to Reduce Exposure
So what are we to do?!
First, here's what I encourage you to take away from this report. It's good to have this information in the back of our minds, but don't be overly concerned! Instead, focus your efforts on providing a varied diet.
- Enjoy a wide VARIETY of foods! This is ALWAYS the answer because the truth is, these kinds of reports are just going to keep coming. Today rice. Tomorrow, who knows! The best thing we can do is focus on balance and moderation. So rather than eating just rice, invite other grains (e.g. oats, barley, farro, quinoa, etc.) and produce to your table. This multigrain rice is such an easy way to do just that!
- It's also a great idea to vary the food sources as heavy metals in the environment vary across the US and around the world. A better rice choice: white basmati rice from California, India, Pakistan, and sushi rice from the U.S were found to have on average, half as much arsenic as most other types.
- Note that brown rice has higher levels of arsenic.
- Check your water as heavy metals sometimes seep into well water, not to mention older pipes may have been made with lead.
Iron

You were probably advised to start your baby or iron-fortified rice cereal. That's because Iron is VERY important for babies especially.
However, instead of relying heavily on the rice cereals, serve those you see in the image above. Some fruits and veggies, like leafy greens, broccoli, prunes are good sources too. Be sure to pair them with vitamin C to help with absorption. Again, focus on VARIETY.

Expert Tips
- You don't need to soak the grains and lentils, but I do recommend soaking the beans for at least 4 hours.
- The two beans I recommend are black beans or small red beans (not kidney). If you want a more moist and softer texture (which is what I recommend for babies especially), use the black beans.
- White rice is most recommended as its softer and chewier in texture.
- Rinse grains by rubbing with hands. Repeat 2-3 times and drain. If you don't have this tool, trust me. You NEED it!
- You can, no you should totally freeze leftovers. Will def come in handy on busy weeknights.
- I recommend using the natural release pressure for this. If you do a quick pressure release, the mixture will be chewier, which makes it difficult for babies to work through.

I love this recipe! It's so easy and healthy, and my family loves it!
Min says
I'm so glad!
Jacqueline says
Hi! I’ve been wanting to try a way to incorporate mixed rice in my toddlers diet and this recipe looks great! Love that it’s also freezable! How would you suggest we reheat the frozen rice though?
Min says
Hi! Thaw in the fridge overnight and reheat in the microwave!
Debby says
I made this with some chicken bone broth I had made in the pressure cooker earlier. I didnt have black beans around so I just substituted for some red adzuki beans. Sooo delicious!
Min says
Ooh love the idea of using bone broth! So glad you enjoyed this recipe!! Thanks for taking the time to let me know 😉
Elina says
Hi, why green lentils? Can I use split red lentils instead? Just happen to have that in the pantry and don't want to buy another bag of lentils. How are they different? Thanks!
Min says
Red lentils are more delicate and you can use it but you'll end up with a mushier mixture, which you might enjoy. If you have a baby, will be easier for them to eat
Jun says
HI Min,
Thank you for the wonder recipe yet again. Just a quick one, I noticed that you used small red beans(azuki beans I assume)? instead of kidney beans? Is there a particular reason to that?
Min says
The kidney beans were still a bit "toothsome" after cooking and tasted too beany. And between the azuki and black beans, I recommend trying the latter first! For some reason, the mixture turns out softer.
Gladies says
Hi Min!
Is it possible to use normal rice cooker for this? If so, does the water level need to be changed? Thanks!
Min says
I believe it will work, but I haven't tried it so not sure about how it would affect the grains:water ratio..sorry!
Edlin says
Can you use canned black beans?
Min says
I actually haven't tried but I believe the mixture will become too wet. If so, perhaps try doing the quick release instead of waiting at least 20 minutes.
Erica says
This recipe looks so yummy—I love a chewy grain side. I recently read that babies don’t have the necessary enzyme to breakdown grains, wasn’t sure the validity of this claim. Would love to know your thoughts. Thanks for all the great recipes, Min!
Min says
So the common argument is that babies don't make enough amylase, which is necessary to digest complex carbs. However, research doesn't support this. Amylase is found both in saliva and pancreas. Salivary amylase is responsible for the initial breakdown of carbs, which research shows that this enzyme becomes abundant between 3-6 months of age. Now, most digestion occurs in the small intestine. It is true that pancreatic amylase levels are very low in babies. BUT there are many other enzymes that help break down the carbs. There's also some research supporting that their bodies will secrete more amylase when introduced to complex carbs. hope this helps ease your mind.
Erica says
It does—thank you!
Brianne says
Hi! This looks great! Just wondering what you would suggest to replace the barley with to make it gluten free? Or would it be better to eliminate and reduce the water? Thanks!
Min says
Oh I definitely think you'll need to replace with another grain. hmm...I haven't experimented with it myself, but I would try buckwheat or amaranth
