Can I use chicken breasts instead of thighs?

Yes, you sure can. The recipe works with either (your choice!). I lean toward thighs because they stay tender, but breasts are totally fine—just cook them until they’re done and don’t overdo it

Can I use bone-in thighs?

You sure can. Plan on adding about 10–15 minutes, depending on size, and always cook until the internal temp hits 165°F .

Do I drain the can of crushed tomatoes?

Nope—use it straight from the can.

A few easy wins: sautéed bell pepper + onion , mushrooms , or a couple handfuls of spinach stirred in right at the end. (If you add watery veggies like zucchini, cook them first so they don’t thin the sauce.)

What if my sauce tastes too acidic?

Two fixes: let it simmer a couple extra minutes, and make sure you didn’t skip the sugar. A little extra Parmesan on top also helps mellow it.

Can I make this ahead of time?

You can! Make it, cool it, then refrigerate. When you’re ready, warm it gently (add a splash of water if it looks tight), then broil with fresh Parmesan right before serving.

Can I freeze chicken spaghetti?

Sure—freeze in a freezer-safe dish. Thaw overnight in the fridge, then reheat covered and broil at the end to bring back that cheesy top.

Do I have to use a cast iron skillet?

Nope, you don't have to. Cast iron is great here because it sears beautifully and can go under the broiler, but any oven-safe heavy skillet works.

Cook time: 30 min
Total time: 35 min
Ingredients: 1 pound boneless, skinless chicken thighs or breasts cut into chunks; 1 tablespoon olive oil; 1/4 teaspoon dried thyme; 1/4 teaspoon dried oregano; 1/4 teaspoon salt; 1/8 teaspoon pepper; 1/2 pound spaghetti (about 1/2 box); 1 28 ounce can crushed tomatoes; 1 tablespoon concentrated tomato paste; 2 cloves garlic - minced; 1 teaspoon salt; 1/2 teaspoon red pepper flakes; 3 tablespoon sugar; 1/4 cup grated Parmesan cheese

Skillet Chicken Spaghetti is my weeknight comfort go-to—seared chicken, spaghetti, and a rich tomato sauce finished under the broiler with Parmesan. One pan, big flavor.

What I Make When I Want Comfort Without the Chaos

There are nights I want a real dinner—something warm and familiar—but I don’t want a sink full of dishes or a complicated plan. That’s exactly why I came up with Skillet Chicken Spaghetti. It’s the kind of meal that feels like comfort food, but it’s still a smart weeknight move: seared chicken, spaghetti, and a rich tomato sauce, all brought together in one skillet.

I started making this because I love pasta (who doesn’t?), but I also like keeping things balanced—plenty of chicken, just enough noodles, and a sauce that tastes like it simmered longer than it did. I finish it the way my family loves best: topped with Parmesan and slipped under the broiler until the edges get bubbly and that cheese turns melty and irresistible. It’s a one-skillet comfort food with weeknight timing.

Enjoy Y’all!

What Makes My Skillet Chicken Spaghetti Different

This isn’t a casserole-style chicken spaghetti—it’s a stovetop skillet dinner with a quick broiled finish, and that’s what makes it special.

I use chicken thighs when I can. They stay tender and forgiving, especially when you’re juggling a weeknight schedule. (You can use breasts too—just don’t overcook them.)

The sauce starts with tomato paste first. I “wake it up” in the warm skillet for a couple minutes before adding garlic and crushed tomatoes. That little step builds deeper flavor fast.

Yes, there’s a little sugar—and it’s on purpose. It smooths out the sharp edge crushed tomatoes can have, so the sauce tastes rounded and cozy instead of acidic.

I don’t drain the crushed tomatoes. You want that liquid—it becomes part of the sauce and helps everything come together just right.

Broiler finish = weeknight “wow” without extra work. Two minutes (and a close eye) melts the Parmesan and makes the skillet look and taste like you went the extra mile.

What You’ll Need for One-Skillet Chicken Spaghetti

Boneless, skinless chicken thighs (or breasts), cut in chunks – I like thighs because they stay juicy and forgiving, but breasts work great if that’s what you have.

Olive oil – just enough to help the chicken sear and keep things moving in the skillet.

Dried thyme + dried oregano – simple herbs that give the chicken that cozy, savory “Sunday supper” flavor without a lot of fuss.

Salt + pepper – season the chicken first so every bite has flavor.

Spaghetti (about ½ box) – the “right amount” of noodles so it still feels balanced and not overly heavy.

Crushed tomatoes (don’t drain!) – this is your sauce base, and the liquid is part of what makes it work.

Tomato paste – adds richness and that “simmered longer than it did” depth.

Garlic (minced) – brings the whole sauce to life (I keep it simple and let it do its job).

Red pepper flakes – optional heat that keeps it from tasting flat (use less if you’ve got sensitive eaters).

Sugar – just enough to smooth out the tomatoes so the sauce tastes rounded instead of sharp.

Parmesan cheese – finishes it off with a salty, bubbly top under the broiler.

How to Make – 4 Easy Steps

Sear the chicken. Season the chicken with thyme, oregano, salt, and pepper. Heat olive oil in a cast iron (or heavy) skillet and cook the chicken until done. Remove to a plate.

Cook the spaghetti. Boil pasta just until al dente (don’t overcook—it finishes in the sauce).

Make the quick skillet sauce. In the same skillet on low, cook tomato paste for 2 minutes, then add garlic for a minute. Stir in crushed tomatoes, salt, red pepper flakes, and sugar; simmer a few minutes.

Combine + broil. Stir spaghetti into the sauce, nestle the chicken back in, top with Parmesan, then broil until the cheese melts and the edges are bubbling. Let it cool 5 minutes before serving.
