Ingredients
If you have any ingredients leftover from this simple chicken spaghetti recipe, check out our Leftover Ingredients Recipe Finder.
- Chicken: Use one boneless, skinless chicken breast or thigh. This dish also works wonderfully with leftover cooked chicken or rotisserie chicken. If you’re picking up a rotisserie chicken, consider using the rest in our 5 Meals From 1 Rotisserie Chicken guide for more easy dinner ideas.
- Butter: Adds richness and helps the onions soften as they cook. Salted butter works well here.
- Onions: Use 1/4 cup of chopped onions for flavor. If you have extra, add them to recipes like slow cooker chickpeas and sausage or lasagna soup for one.
- Flour: All purpose flour thickens the sauce and helps create a creamy consistency. Use a gluten free flour if needed.
- Seasonings: A mix of Italian seasoning, garlic powder, salt, and black pepper provides simple, dependable flavor. If you prefer fresh garlic, add a minced clove and cook it with the onions.
- Milk: Any cow’s milk works. For a richer, creamier sauce, use heavy cream and omit the flour.
- Chicken broth: Low sodium chicken broth helps control the salt level. Vegetable broth is a good substitute. Use remaining broth in single serving crack chicken, Spanish rice for one, or a small broccoli casserole.
- Spaghetti: You’ll need 2 ounces, which is about the width of a quarter when held in your hand. If you have extra pasta, make buttered noodles for one, pesto pasta for one, or pasta al limone.
- Tomatoes: Use 1 small chopped tomato or 1/2 to 3/4 cup canned diced tomatoes. Extra tomatoes can be used in caprese pasta for one, a breakfast sandwich, or ratatouille.
- Cheese: Cheddar cheese melts into the sauce and brings a classic creamy, comforting flavor. Freshly shredded cheese melts best.
Recipe Variations
Customize your chicken spaghetti with these easy, flavorful variations:
- Creamy Mushroom: Add 1/4 cup of sautéed mushrooms for deeper flavor.
- Spicy: Stir in red pepper flakes or a splash of hot sauce for extra heat.
- Vegetable Packed: Mix in chopped bell peppers, spinach, or zucchini for added color and nutrients.
- Gluten Free: Use gluten free pasta and replace the flour with a gluten free alternative.
- Extra Cheesy: Add Parmesan, mozzarella, or Gouda to make the sauce even creamier.
How To Make Chicken Spaghetti For One
These step by step photos and instructions show exactly how to make creamy chicken spaghetti for one. See the recipe box below for ingredient amounts and full recipe instructions.
- Cook the Chicken or Use Leftover Chicken: If using leftover or rotisserie chicken, skip this step. To poach raw chicken, place a boneless, skinless breast or thigh in a 1 or 2-quart saucepan and cover with cold water by about 1 inch. Add a pinch of salt. Bring to a gentle simmer, not a boil. Cover, reduce the heat, and cook for 10 to 12 minutes. Transfer to a plate, cover, and let rest for 10 minutes before slicing.

- Cook the Spaghetti: Bring a small pot of water to a boil. Add the spaghetti and cook for 7 to 8 minutes, until al dente. Drain and set aside.
- Sauté the Onions: In an 8-inch skillet, melt the butter over medium heat. Add the onions and cook for about 4 minutes, until softened.
- Make the Sauce: Stir in the flour and cook for 1 to 2 minutes. Add the seasonings. Slowly pour in the broth and milk, stirring until smooth. Let the sauce simmer for about 5 minutes, until thickened.

- Prepare the Chicken Mixture: Chop the cooked chicken and place it in a bowl. Add the chopped tomatoes and shredded cheddar cheese.

- Combine: Pour the warm sauce over the chicken and cheese. Add the cooked spaghetti and stir until everything is coated and the cheese has melted.

- Serve: Transfer to a bowl and enjoy.

Expert Tips
- Keep Spaghetti From Sticking: If the pasta sits for a few minutes before mixing, toss it with a little olive oil to keep the strands separate.
- Milk or Heavy Cream: Milk creates a lighter sauce. For a richer, creamier version, use heavy cream and skip the flour since the cream thickens on its own.
- Crumb Topping Option: For added texture, combine breadcrumbs with melted butter, sprinkle over the finished dish, and bake at 350°F until golden.
- Doubling the Recipe: Want to make chicken spaghetti for two? Simply double each ingredient to make more servings.

For Poaching Chicken
- 1 (6-ounce) boneless skinless chicken breast or thigh
- ⅛ teaspoon kosher salt

For the Chicken Spaghetti:
- 2 ounces spaghetti
- 1 tablespoon salted butter
- ¼ cup chopped onions

- ¼ teaspoon Italian seasoning
- ¼ teaspoon kosher salt

- ⅛ teaspoon garlic powder
- ½ cup milk
- ½ cup low sodium chicken broth
- 1 small tomato -chopped
- ½ cup shredded cheddar cheese
Instructions
Poach the Chicken (Skip if Using Leftover or Cooked Chicken)
- Cook the Chicken (or Use Leftover Chicken): Place the chicken in a 1 or 2-quart saucepan and cover it with cold water, about 1 inch above the chicken. Add the salt and bring to a gentle simmer—avoid boiling. Reduce the heat, cover, and cook for 10-12 minutes. Transfer to a plate, cover, and let it rest for 10 minutes before slicing to keep it juicy.Note: You can make sure the chicken is fully cooked with a thermometer – it should read 165°F, or ensure the juices run clear when pierced with a knife.
Make the Chicken Spaghetti
- Cook Spaghetti: Bring a medium sized pot of water to a boil. Add the spaghetti and cook until al dente, about 7-8 minutes. Drain and set aside.
- Sauté the Onions: Melt butter in an 8-inch skillet over medium heat. Add chopped onions and cook until softened, about 4 minutes.
- Make the Sauce: Stir in 1 tablespoon of flour and cook for 1-2 minutes, stirring constantly. Add salt, pepper, and seasonings. Slowly pour in the broth and milk, stirring until smooth. Simmer until the sauce thickens, about 5 minutes.
- Assemble the Dish: Chop the cooked chicken and place it in a bowl. Add chopped tomatoes and shredded cheddar cheese.
- Combine Everything: Pour the warm sauce over the chicken and cheese, then add the cooked spaghetti. Stir until everything is evenly coated and the cheese has melted.
- Serve: Transfer to a serving bowl and enjoy.
Notes
-
- Preventing Sticky Spaghetti: If you’re not using the cooked spaghetti right away, toss it with a little olive oil to keep it from sticking together.
-
- Milk vs. Cream: Milk works well for the sauce, but for a richer texture, use heavy cream instead. If using heavy cream, skip the flour, as the cream naturally thickens the sauce.
-
- Crumb Topping Option: For a crispy finish, mix breadcrumbs with melted butter, sprinkle over the dish, and bake at 350°F until golden brown.
-
- Doubling the Recipe: Want to make chicken spaghetti for two? Simply double each ingredient to make more servings.
