Sunshine Casserole–chicken and spaghetti squash in a creamy turmeric orange sauce made with the help of your Instant Pot or slow cooker.

Sunshine Casserole
On a dreary, cloudy day it’s nice to have something yellow and sunny to brighten your day. This yellow dish has yellow spaghetti squash covered in a creamy sauce with turmeric which makes the sauce quite yellow also. I’m a big fan of spaghetti squash because it feels like you’re eating pasta when you’re really eating a vegetable. The sauce is made with sour cream, OJ concentrate, turmeric and it coats everything nicely and adds lots of flavor. The bites of chicken and mozzarella add some protein and rounds out the meal. This makes a great lunch the next day too. Enjoy!
Ingredients/Substitution Ideas
- Spaghetti squash—a small one, about 1 1/2 pounds
- Cooked cubed chicken—rotisserie chicken works well
- Orange juice concentrate–other recipes to make with OJ concentrate are old lady on a bus chicken and Marie Osmond’s chicken.
- Ground mustard
- Kosher salt
- Brown sugar
- Turmeric
- Black pepper
- Sour cream–or greek plain yogurt, full fat is best
- Mozzarella–I love whole milk mozzarella
Steps
Pour 1 ½ cups of water into the bottom of your Instant Pot. Place a trivet into the pot. Cut your squash in half (across the equator) and scoop out seeds. (I used a small paring knife* to cut mine). Place the two halves of the squash into the Instant Pot 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 8 minutes. When time is up move valve to venting and remove the lid. Use tongs to place the two halves of the squash on a cutting board.


Discard the water in the pot. Add chicken, orange juice concentrate, ground mustard, salt, brown sugar, turmeric, pepper and sour cream into the Instant Pot. Stir until combined.

Use forks to shred the flesh of the squash. Add squash into the Instant Pot and stir to coat in the sauce.


Transfer to a 8×8 inch baking dish. Sprinkle mozzarella on top. Bake at 350 for 20 minutes. Serve and enjoy.


Notes/Tips
- Serve with garlic bread, roasted vegetables or greek salad.
- This recipe is gluten-free.
- I love this little paring knife*. I just ordered a second one because I use it all the time.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
- 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 turmeric* are bombay potatoes and supercharged casserole.
