Garlic butter chicken pasta is one of those weeknight dinners that tastes like you spent hours on it but comes together in about 20 minutes. Juicy seared chicken breast over garlicky, buttery spaghetti with fresh Parmesan is the kind of meal that makes everyone stop talking and start eating.
I started making this on Thursday nights when the week had worn me down and takeout felt too easy. The smell of garlic and butter hitting a hot pan is genuinely one of the most satisfying things in a home kitchen. This is comfort food done right.
This garlic butter chicken pasta works because every component earns its place. The chicken gets a proper sear with a seasoned crust, the pasta finishes cooking in the sauce, and the starchy pasta water ties everything together into something silky and cohesive. Your family will thank you for this one.

Ingredients for Garlic Butter Chicken Pasta
I always use freshly grated Parmesan here because pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly into the sauce. Here is everything you need for this garlic butter chicken pasta:
- 1 lb thinly sliced chicken breasts (about 2 medium breasts, cut horizontally in half)
- 1/4 tsp salt, for the chicken
- 1/4 tsp black pepper, for the chicken
- 1 tsp chicken bouillon
- 1 tsp garlic powder
- 1/2 tsp paprika
- 1/2 tsp dried thyme
- 3 tbsp olive oil, divided
- 16 oz spaghetti
- 5 tbsp unsalted butter (I recommend a high-quality butter like Kerrygold since it is the star of the sauce)
- 8 garlic cloves, peeled and minced (my preference is to mince by hand for a more textured, rustic sauce)
- 1/2 tsp crushed red pepper flakes
- 1/4 tsp black pepper, for the sauce
- 3/4 cup freshly grated Parmesan cheese, plus more for serving (in my experience, freshly grated melts far more smoothly than bagged)
- Salt to taste
- 1 tbsp fresh parsley, minced (optional garnish)
Step-by-Step Instructions
I recommend starting the pasta water first so the pasta and chicken finish around the same time. Timing both components together is the key to serving this dish hot and fresh.
Step 1: Bring a large pot of generously salted water to a boil. Add the spaghetti and cook until al dente, about 8 minutes. Before draining, scoop out and reserve 1 cup of pasta cooking water. Drain and set aside. Do not skip the pasta water step.
Step 2: Pat the chicken slices dry with paper towels. Season both sides with salt, pepper, chicken bouillon, garlic powder, paprika, and dried thyme. Drizzle and rub 1 tablespoon of olive oil over both sides to help the crust form properly.
Step 3: Heat the remaining 2 tablespoons of olive oil in a large skillet over medium-high heat until it shimmers. Add the chicken in a single layer and cook for 5 to 6 minutes per side until deep golden brown and the internal temperature reaches 165 degrees F. Transfer to a plate and cover loosely with foil to rest while you make the sauce.
Step 4: Reduce the heat to medium. In the same skillet, melt the butter. Add the minced garlic and crushed red pepper flakes. Stir constantly for about 60 seconds until fragrant. Watch closely here as garlic burns fast and bitter garlic will ruin the sauce. Add the black pepper and half the reserved pasta water. Stir and bring to a light simmer.
Step 5: Add the drained spaghetti directly to the skillet and toss with tongs to coat every strand in the garlic butter sauce. Add the Parmesan and toss again until the cheese melts and the sauce clings to the pasta. Add more pasta water a little at a time if the sauce looks too thick or dry.
Step 6: Taste and adjust salt as needed. Slice the rested chicken and arrange it over the pasta. Top with extra Parmesan and fresh parsley. Serve immediately.
What Goes Well with Garlic Butter Chicken Pasta
The best sides for garlic butter chicken pasta add freshness or a light crunch to balance the richness of the butter and cheese.
Garlic Roasted Vegetables: Roasted vegetables with a similar garlic profile complement this pasta beautifully and add color and fiber to the plate without competing with the sauce.
Simple Green Salad: A crisp Mediterranean chickpea salad with lemon vinaigrette cuts through the richness of the garlic butter sauce and brings a bright, refreshing contrast to each bite.
Homemade Cheesy Breadsticks: Warm, pull-apart cheesy breadsticks are the natural companion to any pasta dinner and double as the perfect tool for scooping up any leftover sauce in the bowl.
Baked Garlic Parmesan Potato Wedges: These crispy potato wedges share the same garlic Parmesan flavor profile as the pasta and work wonderfully as a hearty side for hungrier appetites.
Light Mediterranean Couscous Salad: A cool, herby couscous salad provides a light texture contrast to the warm, rich pasta and makes the overall meal feel more balanced.
How to Store and Reheat Garlic Butter Chicken Pasta
Store leftover garlic butter chicken pasta in an airtight container in the refrigerator for up to 3 days. Keep the sliced chicken and pasta together or separate depending on your preference, but either way works fine for meal prep.
To reheat, warm the pasta in a skillet over medium-low heat with a small splash of water or chicken broth. I recommend against the microwave for pasta with butter-based sauces since it tends to make the noodles sticky and the sauce greasy rather than silky.
Pro tip: this dish is a great candidate for next-day lunch. The garlic flavor deepens overnight and the leftovers often taste even better than the original serving.
FAQs
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs work well here and stay even juicier than breasts. Use the same seasoning and cook until the internal temperature reaches 165 degrees F, which may take a minute or two longer per side.
What can I use instead of spaghetti?
Penne, linguine, bow tie, or angel hair all work well with this garlic butter sauce. Avoid very thick pastas like rigatoni as they do not coat as evenly in lighter butter-based sauces.
Why is my sauce not sticking to the pasta?
The starchy pasta water is what helps the sauce emulsify and cling to the noodles. If the sauce looks greasy or thin, add another splash of pasta water and toss vigorously over low heat until it comes together. Make sure you reserved the water before draining.
Conclusion
This garlic butter chicken pasta is exactly the kind of recipe that earns a permanent spot in your weeknight dinner rotation. It is fast, satisfying, and genuinely delicious every single time. Try it tonight and you will understand why it has become a go-to dinner in so many kitchens. Happy cooking!
