- 1 lb (450 g) boneless, skinless chicken breasts
- 1 tsp Italian seasoning (gluten-free)
- 1/2 tsp garlic powder (gluten-free)
- 1/2 tsp freshly ground black pepper
- 3 tbsp extra-virgin olive oil, divided

For the Sauce and Finish
- 2/3 cup (160 g) gluten-free basil pesto (store-bought GF or homemade; see below)
- 1/2 cup (40 g) finely grated Parmesan, plus more for serving
- Zest of 1 lemon (about 2 tsp)
- 1/4 tsp red pepper flakes (optional, gluten-free)
- Reserved hot pasta cooking water (start with 1/3 cup; up to 3/4 cup as needed)
Basil Pesto (if making from scratch)
- 2 packed cups (40 g) fresh basil leaves
- 1/3 cup (45 g) pine nuts or pumpkin seeds (for nut-free; both gluten-free)
- 1/2 cup (50 g) finely grated Parmesan

- 1–2 tsp fresh lemon juice
- 1/4 tsp kosher salt, plus more to taste

Step-by-Step Instructions
Step 1: Boil and salt the water
Bring a large pot (at least 5 quarts) of water to a boil. Salt generously (about 2 tbsp kosher salt) so the water tastes pleasantly salty. This is key to seasoning gluten-free pasta all the way through.
Step 2: Season and sear the chicken
Pat the chicken dry and season both sides with 1 tsp kosher salt, 1/2 tsp black pepper, 1 tsp Italian seasoning, and 1/2 tsp garlic powder. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add chicken and sear 4–5 minutes per side until golden and the internal temperature reaches 165°F (74°C). Transfer to a plate and rest 5 minutes, then slice thinly across the grain.
Step 3: Blister the cherry tomatoes
Return the skillet to medium-high heat and add the remaining 1 tbsp olive oil. Add cherry tomatoes in a single layer. Cook, shaking the pan occasionally, until skins blister and some juices release, 3–5 minutes. Season with a pinch of salt and pepper. Turn off the heat.
Step 4: Cook the pasta and reserve the starchy water
Add the gluten-free penne to the boiling water and cook to al dente per package directions (typically 9–11 minutes). Scoop out 3/4 cup hot pasta water and set aside. Drain the pasta well.
Step 5: Emulsify pesto with pasta water
With the skillet off the heat, add the drained pasta, pesto, 1/3 cup hot pasta water, and the 1/2 cup grated Parmesan. Toss briskly with tongs until the sauce turns glossy and clings to the penne. Add more reserved water a splash at a time until silky and lightly saucy.
Step 6: Fold in chicken, finish with lemon
Add the sliced chicken and blistered tomatoes to the skillet. Sprinkle in the lemon zest and a pinch of red pepper flakes if using. Toss gently to combine. Taste and adjust salt and pepper. If desired, add another spoonful of pasta water to loosen.
Step 7: Plate and serve
Divide among warm bowls. Top with extra Parmesan and a few small basil leaves if you have them. Serve immediately while glossy and hot.
Pro Tips
- Use certified gluten-free pasta and check labels on spices and pesto to avoid hidden gluten or cross-contamination.
- Toss pesto off the heat. High heat can dull its fresh green color and flavor.
- Under-cook gluten-free pasta by about 1 minute; it continues to soften as it’s tossed with hot sauce.
- Starchy pasta water is your secret sauce. Add gradually until the pesto coats the penne like velvet.
- Slice rested chicken thinly for tender bites that integrate beautifully with the pasta.
Variations
- Dairy-Free: Use a dairy-free, gluten-free pesto and swap Parmesan for a vegan hard cheese or 3 tbsp toasted pine nuts for extra richness.
- Nut-Free: Make pesto with pumpkin seeds or sunflower seeds instead of pine nuts.
- Roasted Tomato Twist: Roast the cherry tomatoes at 425°F (220°C) with 1 tbsp oil and a pinch of salt for 12–15 minutes for deeper sweetness.
Storage & Make-Ahead
Refrigerate leftovers in an airtight container for 3–4 days. Reheat gently in a skillet over low heat with a splash of water to revive the sauce. Pesto can be made 3–5 days ahead and refrigerated (cover the surface with a thin film of oil), or frozen for up to 3 months. Cooked chicken keeps 3 days refrigerated. For best texture, cook the pasta fresh and toss everything together just before serving.
