The 80s are back and I’m all for it! Give me hair scrunchies, neon, and ALL the casseroles. I don’t know why casseroles have such a bad reputation. They’re one dish, they’re creamy, they taste good, and there’s almost always leftovers. Chicken spaghetti is one of those casseroles that needs a little Tiktok glow up because it is good and more people need to make it. Why should baked feta pasta have all the fun?

If you haven’t had it, chicken spaghetti is pure comfort food goodness. Tender pieces chicken mixed with spaghetti, tomatoes, and peppers in a creamy cheesy sauce. Back in the day it was made with canned soup but we can do better than that! And what’s more we can make it all in one pan so there’s minimal clean up.

What is chicken spaghetti

Chicken spaghetti is an American baked spaghetti dish made with a cream sauce, topped with cheese and baked until bubbly. The spaghetti is broken up in small pieces before being cooked.

Why this chicken spaghetti

There are, admittedly, lots of chicken spaghetti recipes out there. What makes this one different is that it’s a one pot chicken spaghetti that can go straight from the stove to the oven to the dinner table. Most pasta dishes, as I’m sure you know have you cook pasta in a large pot of salted water, drain it, then add it to the sauce. We’re going to use the one pot pasta method where pasta is cooked right into the sauce. When you do this the pasta becomes extra flavorful because it’s being cooked in sauce instead of water. The result is a chicken spaghetti that is extremely delicious, creamy, and perfectly cooked.

How to make chicken spaghetti

  1. Sauté the aromatics. In a dutch oven, melt some butter and sauté onions, diced red bell pepper, and garlic until soft and fragrant.
  2. Cook the chicken. Add sliced chicken and cook until golden.
  3. Stir in the liquids. Stir in diced tomatoes, chicken stock and milk to the pan.
  4. Add the pasta. Add the spaghetti and bring everything to a boil. Turn the heat down to a simmer and cook, tossing occasionally, until the spaghetti is tender and cooked through. If it gets too thick, stir in a bit more chicken stock.
  5. Cheese! Season with salt and pepper and stir in some shredded cheese until melted. Top the casserole with more cheese.
  6. Bake. Bake until bubbly and golden and enjoy!

What is one pot pasta?

One pot pasta is a pasta cooking method that was popularized by Martha Stewart back in the early 2000s. It’s a way of cooking pasta where you don’t need to drain the pasta water. Everything, including all of the ingredients for the sauce are put in a large, wide pan along with extra liquid that boils up and cooks the pasta. After the pasta is cooked, it’s tossed until it’s glossy and coated. I love one pot pasta because you can really get a lot of flavor into the noodles because you’re cooking it in sauce instead of water.

Do I need to break the spaghetti?

You don’t have to, but if you want that classic American style, break that pasta! I opted to keep my spaghetti long because I love slurping noodles, but either way tastes amazing. If your pot isn’t wide enough to put all the pasta into the pan, laying flat, I would break the spaghetti so it fits.

What about other pasta shapes?

Feel free to use other kinds of short pasta. I’m pretty sure people used broken short spaghetti back in the day because there wasn’t as much pasta variety available.


  • Aromatics – to add maximum flavor we’re going to use onions, garlic, and a bell red pepper. The onions and pepper add a bit of sweetness and four cloves of garlic add a huge garlicky hit.
  • Chicken – sliced boneless skinless chicken breast is what I prefer but you can use chicken thighs too. You’ll want to cut the chicken into bite size pieces.
  • Spaghetti– just regular spaghetti, not the fancy stuff. But if you do want to get the fancy stuff, you’re looking for bronze extruded pasta with a rough surface so that the sauce can cling to it.
  • Tomatoes – a can of diced tomatoes is going to add some umami.
  • Milk – this is what’s going to make our sauce nice and creamy without the cream.
  • Chicken broth – instead of using water, a little bit of chicken broth is going to help our spaghetti cook up with extra chicken flavor.
  • Cheese – shredded white cheddar (or mozzarella) is stirred into the sauce and layered on top to be baked into a golden brown cheesy crust.
