Ingredients
- 1 pound boneless skinless chicken breasts
- 2 Tablespoons olive oil
- ¼ cup diced yellow onion
- 3 cloves garlic (minced)
- ¼ cup all-purpose flour
- 2 cups 2% milk
- 2 cups chicken broth
- ½ teaspoon salt
- ¼ teaspoon black pepper

- 4 ounces reduced fat cream cheese
- 8 ounces angel hair pasta
- 1 cup shredded Mexican cheese

Notes on ingredients
Using angel hair pasta gives this One Pot Chicken Spaghetti a delicate texture—if you prefer a heartier bite, you can swap for thin spaghetti but cooking time may vary. Reduced fat cream cheese and 2% milk lighten the sauce without sacrificing creaminess. The mild Rotel adds a gentle kick with bright tomato flavor; if you like more heat, use a spicier variety or add a pinch of crushed red pepper. The optional diced tomato added at the end brightens the finished dish with fresh acidity.
Equipment
- Large deep skillet or shallow Dutch oven with lid
- Cutting board and knife
- Wooden spoon or heatproof spatula
- Tongs or fork for shredding chicken
Step-by-step directions
Follow these clear, ordered steps to make the One Pot Chicken Spaghetti. The recipe keeps the original ingredient amounts and sequence but presents the process in a streamlined, easy-to-follow format.
- Prepare ingredients: Dice the yellow onion, mince the garlic, measure the flour, milk, and chicken broth, and open the 10 ounce can of mild Rotel. If you choose to use the optional fresh tomato, dice and seed it and set it aside.
- Heat the oil: Place a large, deep skillet or a shallow Dutch oven over medium-high heat. Add 2 Tablespoons olive oil and let it warm until shimmering but not smoking.
- Cook the chicken: Add 1 pound boneless skinless chicken breasts to the hot oil. Sear the chicken on each side for about 3 to 4 minutes, or until golden-brown on the outside and no longer pink in the center. Reduce the heat if the exterior is browning too quickly. Transfer the cooked chicken to a plate and set aside to cool slightly.
- Sauté the aromatics: Into the same pot, add the ¼ cup diced yellow onion. Sauté for 2 to 3 minutes, stirring occasionally, until the onion becomes soft and translucent. Add the minced garlic (3 cloves) and cook for another 30 to 60 seconds, until fragrant. Scrape up any browned bits from the bottom of the pot to build flavor.
- Create the roux: Sprinkle ¼ cup all-purpose flour over the cooked onions and garlic. Stir continuously for 1 to 2 minutes to cook the flour and form a light roux. This will help thicken the sauce later.
- Add liquids and seasonings: Slowly pour in 2 cups 2% milk while stirring to avoid lumps, then add 2 cups chicken broth. Stir until the mixture is smooth. Season with ½ teaspoon salt and ¼ teaspoon black pepper. Bring the mixture to a gentle simmer over medium heat, stirring occasionally. The sauce should begin to thicken slightly as it heats.
- Return the chicken and add tomatoes: Slice or tear the reserved chicken into bite-sized pieces and return it to the pot. Pour in the 10 ounce can of mild Rotel (undrained), stirring to combine. Nestle 8 ounces angel hair pasta into the simmering sauce, spreading it out so the strands are mostly submerged. Gently press the pasta down if needed to ensure even cooking.
- Simmer until pasta is tender: Cover the pot with a lid and let the pasta cook over medium-low to medium heat. Check after about 6 to 7 minutes—angel hair cooks quickly. Stir gently every few minutes to prevent sticking and to make sure the pasta cooks evenly. Continue simmering until the angel hair is just tender, about 7 to 9 minutes total depending on your stove and pot. If the sauce becomes too thick before the pasta is done, add a splash more chicken broth or milk to loosen it.
- Incorporate the cream cheese: Cut 4 ounces reduced fat cream cheese into several pieces and add them to the pot. Stir until the cream cheese melts completely into the sauce, creating a smooth, creamy consistency. If needed, warm gently and continue stirring until no lumps remain.
- Add cheese and finish: Sprinkle 1 cup shredded Mexican cheese over the top of the pasta and gently fold it into the sauce until melted and evenly distributed. Taste and adjust seasoning if necessary, adding a pinch more salt or black pepper to suit your preference.
- Garnish and serve: If using, stir in the diced and seeded tomato for a fresh burst of flavor right before serving. Serve the One Pot Chicken Spaghetti hot, spooned into bowls or onto plates, and enjoy immediately.
Make-ahead and storage
This dish stores well. Allow leftovers to cool to room temperature, then refrigerate in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat with a splash of milk or chicken broth to restore creaminess, stirring until warmed through. For longer storage, freeze the cooled chicken spaghetti in a freezer-safe container for up to 2 months; thaw overnight in the refrigerator before reheating.
Tips for success
- Use a wide, deep skillet so the angel hair can lay flat and cook evenly. A shallow pot may cause the pasta to clump.
- Angel hair cooks quickly—watch it closely to avoid overcooking. Check for doneness a minute or two before the package directions would suggest.
- Stir gently after adding the pasta to prevent breaking the delicate strands, and scrape the bottom of the pot when sautéing to incorporate flavorful browned bits.
- If the sauce thickens too much while the pasta cooks, add small amounts of milk or broth to reach the texture you like. The sauce should be creamy and able to coat the pasta.
- Shredding or slicing the chicken into similar-sized pieces ensures even distribution so every bite has both chicken and sauce.
Variations and serving ideas
Make this One Pot Chicken Spaghetti your own with a few simple swaps or additions:
- Cheese blend: Try sharp cheddar or Monterey Jack in place of the Mexican cheese for a different flavor profile.
- Veggies: Stir in fresh spinach, frozen peas, or sliced bell peppers toward the end of cooking for color and extra nutrients.
- Spice: Add a pinch of smoked paprika, cumin, or a dash of cayenne to the roux for smoky or spicy notes.
- Herbs: Finish with chopped cilantro or fresh parsley for a bright herbal lift.
Serving suggestions
Serve this One Pot Chicken Spaghetti with a crisp green salad and crusty bread to mop up any extra sauce. A squeeze of lime or a few crushed red pepper flakes at the table allow each person to customize their bowl. Leftovers work great for packed lunches—just reheat and add a handful of fresh veggies for crunch.
