Gulf Coast Casserole

This recipe is made with some easy ingredients you’re likely to already have at your house. You can use frozen or fresh chicken and switch up the vegetables as you see fit. The first night I served it plain all by itself for a lower-ish carb recipe. I served the leftovers the next night over baked potatoes.

This recipe has been adapted from Homan at Home’s Gulf Coast Casserole. The original author makes the recipe with leftover turkey in the oven. I switched it up and made it with chicken and a homemade sauce (instead of canned soups) in the Instant Pot. I hope you love it!

Ingredients/Substitution Ideas

• Chicken broth–or water and Better than Bouillon Chicken Base
• Boneless skinless chicken breasts–or thighs
• Seasoned salt
• Flour
• Butter
• Poultry seasoning
• Garlic powder
• Sour cream
• Frozen vegetables–I used a broccoli, cauliflower and carrot mix
• Ritz crackers

Steps

Pour broth into Instant Pot. Add in the chicken breasts and sprinkle them with the seasoned salt.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 12 minutes (the chicken breasts I used were sliced thin so I only pressure cooked for 10 minutes). When time is up let pot sit for 5-10 minutes. Move valve to venting. Remove the lid. 

Move the chicken to a cutting board and shred or chop. Set aside.

Turn Instant Pot to saute setting. Dip a glass measuring cup into the pot and retrieve about 1 cup of broth. Whisk the flour into the broth until smooth. Stir the mixture into the Instant Pot.

Stir in the 2 Tbsp of butter, poultry seasoning and garlic powder. Once sauce has thickened turn off Instant Pot. 

Stir in the chicken, sour cream and frozen vegetables. 

Sprinkle the crackers over the top and drizzle the butter over the top. If you have an air fryer lid bake for 10 minutes at 400 degrees. If you don’t have an air fryer lid then you can place the Instant Pot liner in the oven and bake at 400 degrees for 20 minutes. 

Serve and enjoy!

Notes/Tips

• Serve with rice or potatoes.
• For this recipe I used a bag of broccoli, cauliflower and carrots. Another option is a bag of mixed vegetables with green beans, corn, peas and carrots. If you’d prefer you can also use fresh vegetables but I would definitely blanch them or partially cook them before adding them into the pot. The original recipe didn’t have any vegetables in it but I felt that this casserole needed something more than just chicken in a creamy sauce with Ritz on top.
• Try adding in some sauteed mushrooms.
• To make this lower carb forego adding the Ritz crackers on top.
• I used my Duo Crisp 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 Ritz crackers Air Fryer Heavenly Chicken and Instant Pot Million Dollar Potato Casserole.
