So, what is Chicken Spaghetti?

Chicken Spaghetti is a dish that is believed to have originated in the South, particularly, in Texas. This dish was created using traditional spaghetti but paired with a creamy, cheesy sauce! With cooked chicken and pasta, it was also a good way to use up any leftover vegetables and canned soups people may have had on hand. People down South would make up this delicious dish and share it with their friends and family at potlucks and family gatherings. My version is a little different, which fits because I’m not a Southern girl! But I can never say no to anything that’s creamy with pasta! YUM!

Equipment Needed:

• Strainer
• Baking Pan
• Mixing Bowl
• Measuring Cups and Spoons
• Chef Knife
• Cutting Board
• Large Skillet

How do I make it?

The first thing you’ll want to do is start cooking your pasta and preheat the oven to 375 F. Lightly grease a 9×13 baking pan. Next, break the spaghetti in half and cook until al dente, per the package instructions. By leaving them with a little bite, they won’t turn to mush in the oven! Drain the pasta and set aside.

Dice your onions and green pepper, mince your garlic. Make your chicken breast if you’re not using a rotisserie, then shred or chop it up into bite sized pieces. Take the cream cheese out of the fridge and allow to soften at room temperature, then cut into cubes. Now let’s start cooking our bacon until crispy, then crumble it, and set aside until ready to use. In the same pan with the bacon grease, cook onion and pepper for a few minutes on medium heat, then add the garlic.

Turn to low and add the tomato and cream cheese. Stir and allow to melt, then add into a large mixing bowl with the chicken, sour cream, half of the bacon, half of the cheese, and the seasonings. Stir to combine.

Carefully fold in the pasta, stir, then pour into prepared baking dish. Garnish with the rest of the cheese and bake until golden and bubbly.

Garnish with remaining bacon and parsley, if desired. Enjoy!

Tips:

• This has a really nice heat that comes on, but if you’re not into that – skip the cayenne all together! If you’d like to turn it up a notch, add in another 1/4 tsp of cayenne! You could also use crushed red pepper or chipotle seasoning!
• This baked spaghetti heats up great, however due to the pasta in this casserole, it is not freezer friendly. If you’d like to freeze it, prepare everything in a pan, except the spaghetti and freeze before baking. Then when you’re ready to bake, you just have to allow it to thaw, cook the spaghetti, mix it in, and bake! This could really simplify some meal prep! This would be the perfect dish to give to a loved one after just having a baby or a surgery!
