This sausage and chicken casserole is a low carb dinner my family enjoys from time to time. It’s one of those meals we can pretty easily throw together, walk away from it, and let it cook.

Even though it’s an Instant Pot casserole, it still requires just a little bit of prep work, like cooking the chicken and browning the sausage. I love that everything is mixed together, though, vegetables and all.

That’s what makes this recipe so delicious. The meats, vegetables, cheeses, and seasonings just all mesh together to form this yummy low carb chicken casserole everyone in our family enjoys.

CAN I USE CAULIFLOWER RICE FOR THIS RECIPE?

You can definitely use already riced cauliflower to make a sausage cauliflower bake in the Instant Pot.

However, I don’t recommend using frozen cauliflower rice, because that will add extra water, ultimately changing both the texture and consistency of the casserole.

I do recommend using either fresh cauliflower or a fresh cauliflower rice over using frozen.

TIPS FOR HOW TO MAKE THIS LOW CARB CHEESY CHICKEN CASSEROLE

Gather your ingredients, per the printable recipe card below.

PREP THE VEGETABLES FIRST…

You’ll need to prep first by washing and chopping (or mincing) the celery, onion, and garlic. Also, wash and chop the cauliflower if you’re not using cauliflower rice.

Then pre-heat the Instant Pot in sauté mode.

ASSEMBLE INGREDIENTS IN THE INSTANT POT

  • Add the butter to your Instant Pot, and let it melt.
  • Sauté the celery, onion, and garlic for about 3 to 5 minutes.

COOK YOUR INSTANT POT CASSEROLE

Turn off the sauté function, press Manual, and set your timer for 8 minutes. Be sure to allow a natural pressure release.

When it’s done, stir the casserole together… If there’s extra water, you may need to turn the sauté function back on and let it cook down just a little bit.

You can top it off with chopped fresh basil or parsley if desired.

9 thoughts on “Instant Pot Sausage and Chicken Casserole”

  1. Instructions are a little confusing on when to add veggies. Veggies are listed in 2 different steps. Steps 6 and step 8. Also what is a salute pot?

  2. I followed this recipe exactly and my instant pot still said burn :( Any thoughts or ideas? I don’t understand why the instant pot doesn’t seem to work well for me.
