Keto Pesto Chicken Bake

Ingredient Notes (Detailed Breakdown)

Chicken Breasts

Use boneless, skinless chicken breasts for clean slicing and even baking. If your chicken breasts are thick, consider cutting them horizontally or pounding them to an even thickness. This ensures uniform cooking and prevents dryness.

Basil Pesto

The star of the dish. Basil pesto is made from fresh basil, garlic, parmesan, olive oil, and pine nuts. You can use homemade pesto for a brighter flavor or store-bought for convenience. Look for a brand without added sugars or fillers to maintain keto compliance.

Cherry Tomatoes

These add a burst of juiciness and natural sweetness to balance the richness of pesto and cheese. They also provide antioxidants such as vitamin C and lycopene. Slice them in halves to help them release flavor into the dish.

Mozzarella Cheese

Low-moisture shredded mozzarella melts beautifully, giving the dish a golden, stretchy cheese topping. It adds healthy fats, helps create a satisfying texture, and keeps the chicken moist during baking.

Parmesan Cheese

Parmesan adds a salty, nutty flavor that intensifies the pesto and complements the chicken. It also helps the cheese topping brown nicely.

Olive Oil

A staple in keto cooking, olive oil provides healthy fats and helps brown the chicken slightly before layering the toppings. It also enhances the flavor of the pesto.

Garlic Powder

Deepens the savory taste without extra moisture. It pairs perfectly with basil, tomatoes, and cheese.

Italian Seasoning

A blend of herbs such as oregano, basil, rosemary, and thyme. This enhances the Mediterranean profile of the dish and adds complexity without extra carbs.

Salt and Pepper

These basic seasonings are essential for bringing out the natural flavors of chicken and pesto. Be cautious with salt since pesto and parmesan can already be salty.

Fresh Basil (Optional)

Used as a garnish for freshness and color. It provides aroma and visual appeal when serving.

Serving Instructions

• Serve the chicken breasts whole or sliced over a bed of zoodles (zucchini noodles) or cauliflower rice for a fully keto plate.
• You can also pair it with sautéed spinach, roasted asparagus, or a crisp green salad.
• For a richer presentation, drizzle extra pesto over the top after baking.
• If entertaining guests, plate individually with a few sliced tomatoes and basil leaves for a professional look.

Tips

• Use thin chicken breasts to ensure even cooking and prevent dryness.
• Homemade pesto provides fresher flavor, but store-bought works well if low-carb.
• Do not overbake, as chicken breasts can dry out quickly.
• Add vegetables such as spinach, mushrooms, or broccoli to make it a one-pan meal.
• Broil for 2 minutes at the end if you want extra golden cheese.
• Marinate chicken in pesto for 30 minutes beforehand for deeper flavor.

Storage Information

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze baked chicken (without tomatoes) for up to 2 months. Thaw overnight and reheat in the oven.
• Reheating: Warm in the oven at 350°F (175°C) for 10–12 minutes or microwave in 60-second intervals.

FAQs

1. Can I use chicken thighs instead of chicken breasts?

Yes, chicken thighs work very well and stay juicier. Adjust baking time to 30–35 minutes since thighs require slightly longer cooking.

2. Is store-bought pesto keto-friendly?

Most are, but read labels carefully. Avoid brands with added sugar or vegetable oils. Look for olive-oil-based pesto for best results.

3. Can I make this recipe dairy-free?

Yes, you can omit the cheese and use a dairy-free pesto. Add nutritional yeast as a cheese substitute for flavor.

4. How can I add more vegetables to this dish?

You can layer spinach under the chicken, add broccoli florets, or mix mushrooms into the baking dish. They cook well with the juices.

5. Why is my chicken coming out dry?

Dryness usually occurs from overbaking. Use thin, evenly sized breasts and remove from the oven as soon as internal temperature reaches 165°F.
