Texas Cheesy Chicken Spaghetti Casserole
There’s something undeniably comforting about a bubbling casserole dish filled with tender chicken, melty cheese, and perfectly cooked pasta. This Texas Cheesy Chicken Spaghetti Casserole recipe transforms simple ingredients into the ultimate comfort food. It’s a family favorite and I am so excited to share it with you!
This is part of my Taste the Nation series where week by week, I’ll explore the foods and flavors of America and recreate the most popular recipes from all 50 states.
There are a million recipes for chicken spaghetti on the internet. Some use cream of mushroom soup, cream cheese, or sour cream as the base of the sauce while others would never dream of adding canned soup or processed cheese to their recipe.
I say to each his own. They are all good in my book, but what gives this recipe a Texas twist is the addition of smokey poblano and jalapeno peppers.
I don’t use canned soup, but I am all about the cheesy goodness that a block of Velveeta adds to any creamy sauce.

Let’s Gather Up the Ingredients
Organizing all of your ingredients ahead of time not only streamlines the cooking process but also ensures you have everything required to complete the dish successfully. You can find the exact amounts in the recipe card below.
- Shredded meat from a whole cooked chicken– You can use a whole rotisserie chicken as a shortcut or follow this recipe for how to poach a whole fryer. I’m telling y’all if you have the time try this method. You’ll have tender, flavorful, chicken and a homemade stock to add to the casserole later.
- Dried spaghetti noodles
- Butter
- Poblano pepper– This pepper adds smokiness, but not a lot of heat
- Jalapeno– If you want to add a little more heat
- Onion
- Fresh garlic
- Kosher salt
- Black pepper
- Flour
- Chicken stock
- Rotel tomatoes
- Heavy Cream
- Shredded cheese– Sharp cheddar, Monterey Jack, Colby Jack, or Mozzarella cheese
Now Let’s Get Cooking
Preheat the oven to 400℉
Roast, peel, and dice the peppers.
This is so simple to do in my Ninja Foodi 10 in 1. I just place the peppers in the air fryer basket, drizzle with a little olive oil, and set the broil function to 15-20 minutes. Flip about half way through.
Tips for success: You could also use the broiler on a conventional oven, but the air fryer is so convenient and easy especially when you are cooking in your RV kitchen.
Once they are charred all the way around, place them in a bowl and wrap them with plastic wrap. Allow the peppers to sweat for about 20 minutes. This makes them easy to peel. Remove the seeds and dice.
Add a generous amount of salt to a large pot of water and bring to a boil. Cook the spaghetti until it’s al dente according to package directions.
You want it to be a little firmer than usual because it will continue to cook in the oven.
In a large skillet, melt the butter over medium heat. Add the diced onions. Season with salt and saute until they have softened (4-6 minutes). Add the minced garlic and cook for another 2 minutes or so then add the diced poblano and jalapeno peppers.
Sprinkle 2 tablespoons of flour over the softened vegetables and stir to incorporate. Cook for one or two minutes. Now, slowly add 2 cups of chicken stock stirring with a whisk to keep the mixture from getting clumpy. Add 1 can of Rotel and the Ranch seasoning. Stir until the sauce starts to thicken.
Add 8 ounces of cubed Velveeta cheese. Turn the heat down to medium-low and allow the cheese to melt, stirring occasionally, 6-8 minutes.
Stir in 1/2 cup of heavy cream and simmer for a few more minutes. Taste for seasoning and adjust salt and black pepper at this point.
Add the cooked spaghetti and shredded chicken into the sauce and mix until everything has been combined.
Pour it into a 9×12 glass casserole dish and top it with 8 ounces of shredded sharp cheddar cheese.
Bake it in the 400℉ oven for 10-15 minutes or until it starts to bubble and the cheese has melted on top.
Garnish with chopped cilantro or parsley if desired.

How to Freeze Chicken Spaghetti
This casserole freezes beautifully! Here’s how:
- Let the casserole cool to room temperature
- Wrap the baking dish tightly in plastic wrap, then add a layer of foil
- Store in the freezer for up to 3 months
- Alternatively, transfer portions to an airtight container for easier reheating
When ready to enjoy, thaw overnight in the refrigerator and reheat until the cheesy sauce is hot and bubbly. It tastes even better the next day.
