This Chicken Alfredo with Roasted Red Pepper and Spinach Spaghetti combines tender, seasoned chicken with creamy Alfredo sauce, sweet roasted red peppers, and fresh spinach tossed through perfectly cooked spaghetti. It’s rich, comforting, colorful, and packed with savory garlic-Parmesan flavor—an easy dinner that feels special enough for a weekend meal.
Can This Recipe Support Weight Loss Goals?
It can fit into a balanced eating plan when served in a sensible portion. Chicken provides lean protein, while spinach and roasted red peppers add vegetables and nutrients. Because Alfredo sauce and pasta can be calorie-dense, keeping the sauce and pasta portions moderate and adding plenty of chicken and vegetables can make the meal more balanced.
Does Chicken Alfredo Fit a High-Protein Lifestyle?
Yes, this recipe can be high-protein friendly because chicken and Parmesan provide substantial protein. Traditional spaghetti adds carbohydrates, so this isn’t a low-carb dish. For a higher-protein option, use a protein-enriched pasta, increase the chicken, and keep the creamy sauce portion controlled.

Directions
- Prepare the chicken.
Pat the chicken breasts dry and season both sides with Italian seasoning, garlic powder, paprika, salt, and black pepper. - Cook the chicken.
Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for approximately 5–7 minutes per side, depending on thickness, until golden and cooked through. - Check the temperature.
The thickest part of the chicken should reach 165°F (74°C). - Rest and slice.
Transfer the chicken to a cutting board and let it rest for 5 minutes before slicing into strips. - Cook the spaghetti.
Bring a large pot of salted water to a boil. Cook the spaghetti according to the package directions until al dente. - Reserve pasta water.
Before draining, reserve approximately ½ cup pasta water. - Prepare the Alfredo sauce.
In the same skillet used for the chicken, melt the butter over medium-low heat. - Add garlic.
Add minced garlic and sauté for approximately 30–60 seconds, just until fragrant. - Add the cream.
Pour in the heavy cream and stir gently. Simmer for approximately 3–4 minutes without allowing it to boil aggressively. - Add Parmesan.
Reduce the heat to low. Gradually stir in the Parmesan cheese until melted and the sauce becomes smooth and creamy. - Season the sauce.
Add Italian seasoning and black pepper. Taste and adjust the salt if necessary. - Add the spinach.
Stir the fresh spinach into the warm Alfredo sauce and cook for 1–2 minutes, until wilted. - Add roasted red peppers.
Stir in the sliced roasted red peppers and warm for another minute. - Add the spaghetti.
Transfer the drained spaghetti into the skillet and toss gently until thoroughly coated. - Adjust the sauce.
If the Alfredo sauce is too thick, add reserved pasta water 1 tablespoon at a time until you reach your preferred consistency. - Add the chicken.
Fold in the sliced chicken or arrange it over the top. - Garnish and serve.
Finish with fresh Parmesan, parsley, black pepper, or red pepper flakes. Serve immediately.
High-protein cooking tip: Use a protein-enriched spaghetti and lean chicken breast to increase the protein per serving. You can also increase the spinach and roasted peppers without substantially changing the overall flavor.

Frequently Asked Questions
1. Can I use rotisserie chicken?
