Moo Moo Casserole–Tender bites of beef stew meat with mushrooms and creamy brown rice. An easy dinner made in your Instant Pot.

Moo Moo Casserole
I know the Chick-fil-A cows say to eat chicken but sometimes you just need some beef for dinner! This recipe uses beef stew meat which becomes fork tender in the Instant Pot in a few minutes. With beef, mushrooms, and sour cream it reminds me of beef stroganoff with rice instead of noodles. I love using the brown rice for a whole grain chewier option. I fed this to Skyler and 3 of his friends and the pot was scraped clean. Win!
Ingredients/Substitution Ideas
- Olive oil–or canola, vegetable
- Beef stew meat–or chuck roast/steak cut into bite size pieces
- Lipton’s onion soup mix–or homemade
- Water
- Brown rice–for white rice see the notes section
- Mushrooms
- Black pepper
- Sour cream
- Parmesan cheese
Steps
Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Brown the beef for about 5 minutes, flipping halfway through.

Stir in the onion soup mix and coat the beef.

Pour in the water and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.
Sprinkle in the rice. Dump mushrooms and pepper on top of rice.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 25 minutes. When time is up let pot sit for 10 minutes and then move valve to venting. Remove the lid.
Stir in the sour cream.

Serve topped with parmesan cheese.

Notes/Tips
- Serve with green beans, or broccoli.
- This recipe can be gluten free if you use a gluten free onion soup mix.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot. If you use the 3 quart pot you will need to brown the meat in batches.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- Other recipes you can make with beef stew meat are cheater beef stew and calm down casserole.
- If you’d like you can make this with white rice with a few adjustments. Do steps 1-4 but do not add in the rice. Pressure cook for 20 minutes. Do a quick release. Sprinkle in the rice. Pressure cook for 10 more minutes with a 10 minute natural pressure release. Remove lid. Stir in sour cream. Serve.

Instant Pot Cheater Korean Beef and Brown Rice
A quick version of a classic recipe made in your electric pressure cooker. The best part is that the beef and rice cook at the same time in the same Instant Pot.
Instant Pot Chicken and Brown Rice
Whole chicken legs are seasoned and cooked until tender in your electric pressure cooker and then browned under your broiler. Brown rice is cooked alongside the chicken and comes out with a creamy consistency–almost risotto-like. And no cream of soups are used in this recipe!

Made this last night…only change I made was to add peas and corn right before I added the sour cream. This was a wonderful recipe!
Thanks Jeannie!
Very good as a base recipe! I can imagine all kinds of variations for swapping out ingredients & making a variety of dinners. Thanks for the inspiration.
You’re welcome Chefette!
Can Moo Moo casserole be made in a slow cooker/crockpot? the instant pot recipe sounds so delicious, but I only have a crockpot.
thank you
Sure you could try it…I would brown the meat on the stove first. Then add ingredients into slow cooker (not the sour cream) cook on low for 6 hours or until rice is cooked through and beef is tender. Stir in the sour cream.
Same here @Marie. I’m hoping there will be some recipe’s for the crockpot. Such as this one
Can you give the conversion to parboiled white rice for this recipe please?
Hey, KK!
Look up where she has Notes/Tips & she tells how to do this with white rice. I’m pretty sure that would include the parboiled as well. (If I’m wrong, sorry, Karen will tell you the correct way)
