Relax Dude Casserole–an Instant Pot recipe with mashed potatoes, a creamy chicken and mushroom sauce topped with cheddar and bacon crumbles.
Relax Dude Casserole
This is a winning dinner in the flavor department! My family all loved it. This dinner does take a little bit of forethought because you have to marinate the chicken. I told my husband when he asked me when dinner was going to be ready “marinating chicken takes some time, so relax dude it is worth the extra time!” And the list of ingredients seems super long but most of the ingredients are items you’ll have on hand (so relax, dude!). Try out this super yummy dinner soon!
Ingredients/Substitution Ideas
- Boneless skinless chicken thighs–or breasts, tenderloins
- Olive oil–or canola oil

Steps
Add the chicken and all the marinade ingredients into a ziplock bag or an airtight container. Stir well. Place in the refrigerator for anywhere from 1 hour to 8 hours.
Turn Instant Pot to saute setting. When display says HOT add in the butter and let it melt. Add in the onion and mushrooms and saute for 5 minutes. Stir in the salt, pepper, garlic powder and parsley.
Pour in the water and scrape bottom of pot so that nothing is sticking. Stir in the Better than Bouillon.
Add the chicken into the pot (without the marinade). Turn off Instant Pot.
Add potatoes into a steamer basket* and place the basket into the Instant Pot on top of the chicken.
Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 5 minutes. When time is up let pot sit for 10 minutes then move valve to venting. Remove the lid.
Move steamer basket out of the pot. Pour the potatoes into a bowl and mash well. Stir the milk, butter and salt and pepper to taste into the mashed potatoes. Set aside.
Turn Instant Pot to saute setting. In a small bowl stir together 3 Tbsp or cornstarch with ¼ cup of water. Stir together until smooth. Stir the slurry into the pot to thicken the sauce. Turn off the pot.
Stir some of the sauce into the cream to temper it. Stir the cream into the pot.
To serve place a scoop of mashed potatoes onto a plate, a big scoop of the chicken and sauce and then sprinkle cheese and bacon on top. Enjoy!

Loved this! So did the family, but I put the mushrooms in the food processor because my husband doesn’t like mushrooms, and although the sauce had little mushroom flecks all throughout it, he didn’t question it and happily chowed down. (I do the same with celery because another family member hates it. He’s clueless about it as well.) One thing…I have the exact same steamer basket that you show here, but if I sit it on top of food or a trivet, I can’t get the lid on the IP. My cooker is around eight years old – are they making them taller now? It really doesn’t matter, because if I start boiling the potatoes, as this recipe calls for, when I start the IP, the potatoes are done when it’s time to release the steam. Anyway, thanks for the yummy recipe!
Good tricks to get people to eat vegetables! I am not sure about the steamer and the pot…mine fits in fine so I don’t know!
Used Diary Free heavy cream and it tastes great! Will be making this again.
I’m just wondering if I could make this in the crockpot?
I don’t own an instant pot. Can this be cooked in the oven?
Could I sub just regular white vinegar in place of the wine vinegar? I never have those fancy vinegars, not a fan of them….
Other than that, this recipe sounds divine!
yes you can do that!
Hey Karen! OMGoodness, this sounds so delicious, can’t wait to try it. I usually read your recipes out loud to that “bottomless pit” I married & he tells me if/when he wants it. I have no intention of reading this one to him or he will nag, nag, nag until I make it. ;-} Will be back with stars for sure! Thanks again.
Just tell him to “RELAX DUDE!”
You are soooo right. However, that only works if I follow it up with the fly swatter. ;-}
Made this for dinner. Oooo-la-la!! Was so very delicious, that chicken & sauce was divine. Served with steamed Brussels sprouts. Was BIG winner!!! Thanks again for all you do “behind the scenes” to come up with all these amazing recipes for us.
