Ingredients for Chicken Pasta with Cowboy Butter (One Pan, 30 Minutes)

Exact amounts are in the printable recipe card below — here's what you'll need at a glance.

Main Ingredients

• 1 lb boneless, skinless chicken thighs
• 8 oz penne pasta
• 6 tbsp unsalted butter
• 4 garlic cloves, minced
• 1 lemon, zested and juiced
• 1 tsp chili flakes
• 1/2 tsp smoked paprika
• Salt and black pepper to taste
• Fresh parsley, chopped, for garnish

Seasonings & Flavors

• 1 tsp chili flakes
• 1/2 tsp smoked paprika
• Salt and black pepper to taste
• Lemon zest from 1 lemon
• Lemon juice from 1/2 lemon

Optional Toppings

• (Optional) Grated Parmesan cheese
• (Optional) Extra lemon wedges
• (Optional) Chopped fresh basil

Ingredient Notes

• Chicken thighs: Boneless thighs stay juiciest; breasts work if monitored closely and pulled at 160°F.
• Unsalted butter: Lets you control salt; if using salted, skip added salt in the dish.
• Penne pasta: Short cuts like penne capture the butter sauce in every bite; rigatoni or fusilli also work.
• Fresh garlic: Non-negotiable for bold flavor; jarred garlic can taste bitter when heated in butter.
• Chili flakes: Adjust amount to taste; swap with cayenne for more heat or omit for a mild version.
• Lemon zest: Brightens the rich butter; bottled juice can’t replace fresh zest’s oils.

How to Make Chicken Pasta with Cowboy Butter (One Pan, 30 Minutes) Step by Step

Prep the ingredients

Bring chicken to room temperature for 15 minutes. Pat dry and season both sides with salt, pepper, and smoked paprika. Mince garlic, zest and juice the lemon, and chop parsley. Bring a large pot of salted water to a boil for the pasta.

Cook the pasta

Boil penne until 1 minute shy of package directions (about 9–10 minutes). Reserve 1/2 cup pasta water, then drain. Set pasta aside.

Sear the chicken

Melt 3 tablespoons butter in a large cast iron skillet over medium-high heat. Once foaming, add chicken in a single layer. Sear 5–7 minutes per side without moving, until deep golden and internal temp reads 160°F at the thickest part. Transfer to a plate and tent with foil.

Make the cowboy butter sauce

Reduce heat to medium-low. Add remaining 3 tablespoons butter to the same skillet with garlic and chili flakes. Cook 30–60 seconds until fragrant, stirring constantly—do not let garlic brown. Stir in lemon zest and juice.

Combine and finish

Add drained pasta to the skillet. Toss vigorously, adding splashes of reserved pasta water until a glossy sauce coats the noodles. Slice chicken against the grain and arrange over pasta. Garnish with parsley and optional Parmesan.

Pro Tips for the Best Chicken Pasta with Cowboy Butter (One Pan, 30 Minutes)

• Ingredient prep: Bring chicken to room temperature for 15 minutes before cooking to ensure even searing.
• Common mistake and fix: Overcooking chicken is the #1 mistake. Use an instant-read thermometer and pull the chicken at 160°F; carryover heat brings it to 165°F. If it’s already dry, toss the slices in a bit of warm butter sauce to revive moisture.
• Timing: Cook the pasta 1 minute less than package directions. It finishes in the sauce and stays perfectly al dente.
• Texture: Reserve ½ cup of starchy pasta water before draining. A splash helps the cowboy butter cling to every noodle without turning greasy.
