This Baked Keto Pesto Chicken is the kind of weeknight dinner you’ll make once and keep on repeat. It’s juicy, garlicky, and full of fresh basil flavor with barely any effort. You’ll only need a handful of ingredients, and most of the work happens in the oven.
It’s low-carb, high-protein, and pairs easily with a simple salad or roasted veggies. If you want a meal that feels special but cooks itself, this is it.
Ingredients
Method
- Preheat the oven: Set your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish with 1 tablespoon of olive oil.
- Prep the chicken: Pat the chicken breasts dry with paper towels. This helps the pesto cling and promotes even cooking.
- Season simply: Sprinkle both sides with salt, pepper, and garlic powder. Keep it light—pesto brings plenty of flavor.
- Add pesto: Spread about 2–3 tablespoons of pesto over each chicken breast, coating the tops evenly. Place them in the prepared baking dish.
- Add tomatoes (optional): Scatter grape tomatoes around the chicken. Drizzle with the remaining 1 tablespoon of olive oil for extra richness.
- Bake uncovered: Place the dish in the oven and bake for 18–22 minutes, depending on thickness. Thicker pieces will need closer to 25 minutes.
- Check doneness: The chicken is done at an internal temperature of 165°F (74°C). Use an instant-read thermometer for accuracy.
- Add cheese: Sprinkle mozzarella and Parmesan over the chicken. Return to the oven for 3–5 minutes, until the cheese melts and bubbles.
- Rest and garnish: Let the chicken rest 5 minutes. Top with fresh basil or parsley. Serve with lemon wedges for a bright finish.
Why This Recipe Works
- Simple ingredients, big flavor: Pesto, chicken, and cheese do the heavy lifting. No long prep or complicated steps.
- Oven-baked for juicy results: Baking keeps the chicken tender and evenly cooked without babysitting a skillet.
- Perfect for keto: This dish is naturally low in carbs and higher in healthy fats and protein.
- Customizable: Use store-bought or homemade pesto, swap cheeses, or add low-carb veggies to the pan.
- Great for meal prep: It reheats well and stays flavorful for days.

Storage Instructions
- Refrigerate: Store leftovers in an airtight container for up to 4 days.
- Freeze: Freeze cooked chicken (without tomatoes, if used) for up to 2 months. Thaw in the fridge overnight.
- Reheat: Warm in a 300°F (150°C) oven for 12–15 minutes or microwave in short bursts. Add a spoon of extra pesto if it looks dry.
Why This is Good for You
- Low-carb, high-protein: Supports ketosis while keeping you satisfied.
- Healthy fats: Olive oil and nuts in pesto provide heart-friendly fats that help with satiety and flavor.
- Nutrient-dense: Basil brings antioxidants, and tomatoes (if used) add vitamin C and lycopene.
- Minimal sugar and starch: No breading or heavy sauces to spike carbs.
What Not to Do
- Don’t overbake: Dry chicken is the fastest way to ruin this dish.
Use a thermometer for perfect timing.
- Don’t skip drying the chicken: Moisture can dilute the pesto and affect texture.
- Don’t drown it in pesto: A generous coating is great, but too much can get oily. About 1 cup for 4 pieces is ideal.
- Don’t use sweet tomato sauces: Keep it keto by avoiding high-sugar add-ins.
- Don’t salt heavily if your pesto is salty: Taste your pesto first and adjust seasoning accordingly.
Variations You Can Try
- Pesto swap: Try sun-dried tomato pesto (pesto rosso) for a deeper, slightly smoky flavor. Check labels for added sugars.
- Cheese twist: Use sliced fresh mozzarella for a caprese-style melt, or provolone for a sharper bite.
- Add veggies: Toss zucchini rounds, asparagus, or broccoli florets with olive oil and roast in the same pan.
- Thighs instead of breasts: Boneless, skinless thighs stay extra juicy.
Bake 22–28 minutes, then add cheese.
- Stuffed version: Slice a pocket in each breast and stuff with a spoon of pesto and a slice of mozzarella. Secure with toothpicks and bake.
- Dairy-free: Skip the cheese or use a dairy-free melt. Choose a pesto made without cheese or make your own with nutritional yeast.
FAQ
Can I use frozen chicken breasts?
Yes, but thaw them completely first for even cooking.
Pat dry after thawing to remove excess moisture before adding pesto.
Is store-bought pesto okay for keto?
Usually, yes. Check the label for added sugars or cheap oils. Look for versions made with olive oil, nuts, basil, garlic, and cheese.
How do I keep chicken from drying out?
Use an instant-read thermometer and pull the chicken at 165°F (74°C). Let it rest 5 minutes before slicing to keep juices inside.
What should I serve with it?
Try a simple arugula salad, roasted asparagus, sautéed zucchini, or cauliflower mash.
Keep sides low-carb to stay keto-friendly.
Can I make this ahead?
Yes. Season and coat the chicken with pesto up to 12 hours in advance. Cover and refrigerate, then bake when ready.
Add cheese near the end as directed.
What if I don’t have mozzarella?
Use provolone, Monterey Jack, or even a bit of crumbled goat cheese. Adjust amounts to taste, but avoid overly salty cheeses if your pesto is salty.
How do I make homemade pesto keto?
Blend fresh basil, olive oil, pine nuts or walnuts, garlic, Parmesan, salt, and pepper. Keep it thick and bright.
No sugar needed.
Can I use bone-in chicken?
You can, but adjust time. Bone-in thighs or breasts will take longer—usually 30–40 minutes. Add cheese for the final few minutes to melt.
