Ingredients Notes

Recipe Steps
Step 1
Start by seasoning the chicken with salt, pepper, and your choice of herbs. Sear the chicken in the Instant Pot using the sauté function until lightly browned.
Step 2
Add chopped vegetables to the pot. Sauté for a few minutes to bring out their flavors and complement the chicken.
Step 3
Pour in the chicken broth and stir to combine. Ensure the liquid covers the chicken and vegetables adequately to ensure even cooking.
Step 4
Lock the Instant Pot lid and set it to pressure cook on high for about 10 minutes. Allow the pressure to release naturally after cooking.
Step 5
Once the pressure has released, carefully open the lid and stir in any additional seasonings to taste. Let it sit for a few more minutes to allow the flavors to meld together.
Storage Options
To store leftovers, transfer the casserole to an airtight container and refrigerate for up to 3 days. For longer storage, divide into portions, place in freezer-safe containers, and freeze for up to 3 months. Reheat in the microwave or on the stove, adding a splash of broth if needed to keep it moist.
Variations & Substitutions
For a dairy-free version, replace cream-based ingredients with coconut milk. Swap in quinoa or brown rice for added fiber. For a vegetarian twist, substitute chicken with chickpeas or tofu, adjusting cooking time accordingly.
