Missionary Casserole

This casserole of layered mashed potatoes, shredded chicken, mixed vegetables, barbecue sauce and cheese is a winner! My parents were in town when I made it and we all agreed that it was tasty meal (and it is all in one dish). The cool thing about this recipe is that you cook the chicken and the mashed potatoes at the same time in the Instant Pot.

This recipe comes from Holman at Home. I changed it up to use the Instant Pot for the prepping of the chicken and potatoes. Diane, the author states how the casserole came to be, “One fine Sunday a year or two ago, I got a phone call from the missionaries at my church. I had signed up to feed them dinner, but had totally forgotten. I had basically nothing in the house and no time to get anything. Thankfully, there were leftovers in the fridge, and from this moment of desperation Missionary Casserole was born. I slapped it together and threw it on the table with a side salad and some leftover biscuits. What surprised me was how much the missionaries liked my concoction. They requested it the next time I signed up to feed them. Necessity is the mother of invention!” I love this story! Sometimes the best recipes come about by happenstance.

Ingredients/Substitution Ideas

• Chicken broth–or water and Better than Bouillon
• Boneless skinless chicken thighs–or chicken breasts
• Kosher salt
• Pepper
• Onion powder
• Garlic powder
• Red pepper flakes
• Red potatoes–or peeled Russet potatoes, yukon gold potatoes
• Butter
• Milk
• Frozen mixed vegetables–mine had a mix of corn, peas, green beans, carrots
• Barbecue sauce–I used Sweet Baby Ray’s
• Colby jack cheese–or cheddar

Steps

Pour the broth into the Instant Pot. Place chicken into bottom of pot evenly. Sprinkle the chicken with 1 tsp kosher salt, 1 tsp pepper, onion powder, garlic powder and red pepper flakes.

Place a trivet (I used a long-legged trivet) on top of the chicken. Place halved potatoes on top of the trivet.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 12 minutes. When time is up let pot sit for 10 minutes and then move valve to venting. Remove the lid.

Place the potatoes into a mixing bowl and mash. Stir in the butter, milk, 1 tsp kosher salt and ½ tsp pepper.

Following the cooking directions on the vegetable package (I microwaved mine for 5 minutes).

Discard the broth in the pot and shred the chicken.

Preheat oven to 350 degrees F. In a 9×13 inch dish spread the mashed potatoes, add the chicken evenly over potatoes then the vegetables.

Drizzle the barbecue sauce over the vegetables.

Finally sprinkle the cheese on top.

Bake for 15 minutes. Serve and enjoy!

Notes/Tips

• This is a one pot meal but you can serve fruit or bread on the side.
• I used my 6 quart Instant Pot* with a long legged trivet*.
• This recipe makes quite a large portion (a 9×13 inch pan). If you want you can easily halve this recipe and use a 9×9 inch dish instead.
• You can use fresh or frozen chicken. Use the same cooking time for both. You can also use a combination of thighs and breasts.
• This recipe can come together quickly when you have leftover mashed potatoes and shredded chicken on hand. If you do use leftovers you can skip the whole part with the Instant Pot. However, if they are cold leftovers you’ll need to bake longer in the oven. Probably up to an hour so they can all warm through.
• Try using whatever kind of frozen vegetables you like best. Broccoli, cauliflower, peas, corn, asparagus, etc.
• I just eyeballed the barbecue sauce and squeezed it straight out of the bottle.
• This recipe can be gluten-free if you use gluten-free barbecue sauce.
• Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
