    How to Make Spicy Southern Cheesy Chicken Spaghetti Casserole

    Follow these simple steps to prepare this delicious dish:

    Step 1: Prep the Chicken and Veggies

    Preheat your oven to 375°F (190°C). Dice the cooked chicken into bite-sized pieces. Finely chop the onion and mince the garlic.

    Step 2: Sauté the Aromatics

    Melt the butter in a large skillet over medium heat. Add the onion and sauté until softened, about 5 minutes. Stir in the garlic and cook for another minute until fragrant.

    Step 3: Make the Cheese Sauce

    In the same skillet, whisk in the all-purpose flour and cook for one minute, stirring constantly. Gradually whisk in the chicken broth and milk, ensuring there are no lumps. Bring to a simmer, stirring occasionally, until the sauce thickens slightly. Stir in the chili powder and paprika. Season with salt and pepper to taste. If using agar-agar, sprinkle it in now and whisk thoroughly.

    Step 4: Assemble the Casserole

    In a large bowl, combine the cooked spaghetti, chicken, and cheese sauce. Stir until everything is well coated. Pour the mixture into a greased 9×13 inch baking dish.

    Step 5: Bake to Perfection

    Top the casserole with the shredded cheddar and Monterey Jack cheeses. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.

    Step 6: Serve and Enjoy

    Let the casserole rest for a few minutes before serving. A simple green salad makes a perfect accompaniment. Enjoy!

    FAQs

    Can I make this Spicy Southern Cheesy Chicken Spaghetti Casserole ahead of time?

    Absolutely! This casserole is even better the next day, as the flavors meld beautifully overnight. You can assemble the entire dish the day before, cover it tightly, and refrigerate it.

    What kind of cheese is best for this Spicy Southern Cheesy Chicken Casserole?

    While the recipe calls for cheddar, feel free to experiment! A blend of sharp cheddar and Monterey Jack adds a delightful creaminess. You could even sneak in some pepper jack for an extra kick! The key is to use a cheese that melts well, so avoid anything too hard or crumbly. Ultimately, the best cheese is the one that you enjoy the most, so don’t be afraid to get creative and personalize this recipe to your cheesy heart’s content!

    Is this Spicy Southern Cheesy Chicken Spaghetti Casserole gluten-free?

    Not as it is written, since regular spaghetti contains gluten. However, you can easily adapt this recipe to be gluten-free by substituting gluten-free spaghetti. Make sure to choose a brand that holds its shape well when cooked, so your casserole stays nice and intact. Many gluten-free pasta options are available these days, so finding a suitable replacement should be a piece of cake (or a piece of gluten-free pasta, rather!).

    How can I adjust the spice level in this Spicy Southern Cheesy Chicken Spaghetti Casserole?

    The recipe provides a medium spice level, but you can easily customize it to your preferences. For a milder dish, reduce the amount of cayenne pepper or omit it entirely. If you prefer things fiery hot, add a pinch or two more cayenne, or even incorporate some chopped jalapeños or a dash of your favorite hot sauce. Remember, spice is subjective; adjust the recipe to suit your personal heat tolerance!
