Keto Chicken Creamy Pesto Bake – A Comforting, Low-Carb Weeknight Favorite
This dish checks all the boxes: rich, comforting, and surprisingly simple. Tender chicken bakes in a creamy basil pesto sauce, topped with melty mozzarella and a touch of Parmesan. It feels like a cozy restaurant meal, but it’s easy enough for a busy weeknight.
Everything happens in one pan, the flavors are bold, and it pairs beautifully with simple sides like roasted veggies or a fresh salad. If you’re eating low-carb, this will quickly become a regular in your rotation.
Ingredients
Method
- Preheat and prep: Set your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish. Pat the chicken dry with paper towels for better browning and texture.
- Season the chicken: In a bowl, toss chicken with olive oil, salt, pepper, Italian seasoning, and onion powder. Make sure each piece is evenly coated.
- Quick sear (optional but recommended): Heat a skillet over medium-high. Sear chicken 1–2 minutes per side to get a little color. Transfer to the baking dish. If skipping this step, place seasoned chicken directly in the dish.
- Make the sauce base: In a medium bowl, whisk together pesto, heavy cream, softened cream cheese, minced garlic, and lemon zest (if using). It should be smooth and spoonable. If too thick, add a splash more cream.
- Assemble the bake: Pour the creamy pesto sauce over the chicken and gently spread to cover. Sprinkle shredded mozzarella and grated Parmesan evenly on top.
- Bake: Place the dish in the oven and bake for 20–25 minutes for thighs (25–30 for thicker breasts), until the chicken reaches an internal temperature of 165°F (74°C) and the sauce is bubbling.
- Broil for color: Turn the broiler on high for 1–2 minutes to brown the cheese slightly. Watch closely to avoid burning.
- Rest and garnish: Let the bake rest for 5 minutes so the sauce settles. Top with torn fresh basil and a pinch of red pepper flakes if you like a little heat.
- Serve: Spoon extra sauce over the chicken. Pair with zucchini noodles, roasted broccoli, cauliflower mash, or a crisp green salad.

How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently in a covered oven-safe dish at 325°F (165°C) until hot, or microwave in short intervals.
Add a splash of cream if the sauce thickens too much.
Health Benefits
- Low-carb, high-fat balance: This dish fits a ketogenic approach by prioritizing fats and keeping carbs low, helping many people maintain steady energy and satiety.
- Quality protein: Chicken provides essential amino acids for muscle repair and daily function.
- Healthy fats from pesto: Olive oil, nuts, and cheese in pesto offer monounsaturated fats and fat-soluble vitamins that support heart and brain health.
- Micronutrients: Basil brings antioxidants; Parmesan adds calcium; garlic contributes compounds that may support immune function.
Common Mistakes to Avoid
- Using watery mozzarella: Fresh mozzarella releases more moisture and can thin the sauce. Use low-moisture, shredded mozzarella for a creamier result.
- Skipping the seasoning on chicken: Salt and spice the chicken itself. Don’t rely only on the sauce for flavor.
- Overbaking: Dry chicken ruins the dish.
Check temperature early, especially if using breasts.
- Too much pesto: It’s tempting, but extra pesto can make the sauce oily. Stick to the measurements or add a little more cream to balance.
- Cold cream cheese: It won’t blend smoothly. Soften it first for a silky sauce.
Variations You Can Try
- Spinach boost: Stir a cup of chopped fresh spinach into the sauce before baking for extra greens.
- Mushroom and pesto: Sauté sliced mushrooms in butter until golden, then tuck them around the chicken before adding the sauce.
- Sun-dried tomato twist: Add 1/4 cup chopped oil-packed sun-dried tomatoes to the sauce for a sweet-tangy pop.
- Dairy adjustments: Swap cream cheese for mascarpone for a lighter, silkier texture.
Use Gruyère or provolone instead of mozzarella for a different melt.
- Breast vs. thighs: Use thin-sliced breasts or cut large breasts in half horizontally to keep cook times even and prevent dryness.
- Nut-free pesto: If avoiding nuts, use a nut-free pesto or make your own with pumpkin seeds.
FAQ
Is store-bought pesto okay for keto?
Yes. Many jarred pestos are low in carbs, but check the label for added sugars or fillers. Choose a brand with olive oil, basil, nuts, cheese, and minimal extras.
Can I make this with bone-in chicken?
You can, but the cook time will increase.
Sear bone-in thighs first, then bake 30–40 minutes, or until they reach 165°F (74°C). Cover loosely with foil if the cheese browns too quickly.
What side dishes keep this meal keto?
Great options include roasted broccoli, sautéed zucchini, cauliflower rice, spiralized zucchini noodles, or a simple arugula salad with olive oil and lemon.
How can I lighten the calories without losing flavor?
Use half-and-half instead of heavy cream and reduce the mozzarella by a third. Keep the Parmesan for sharpness, and add lemon zest and pepper to punch up flavor.
Can I make it ahead?
Yes.
Assemble the dish up to the cheese step, cover, and refrigerate up to 24 hours. Bake straight from the fridge, adding 5–10 extra minutes. Check doneness with a thermometer.
Why did my sauce separate?
This can happen if the heat is too high or ingredients weren’t fully combined.
Whisk the sauce well before adding it, use softened cream cheese, and avoid overbaking.
What can I use instead of cream cheese?
Mascarpone blends in easily and tastes luxurious. A few tablespoons of sour cream can also work, though the sauce will be slightly tangier and looser.
