Easy Creamy Pesto Chicken Bake

Introduction

This creamy pesto chicken bake is the kind of weeknight dinner that feels like a mini celebration. We’re talking juicy, golden-seared chicken breasts nestled in a silky, garlicky pesto cream sauce, then dotted with sweet cherry tomatoes, tangy Kalamata olives, and bright capers. It’s all finished in the oven, so the flavors get time to mingle and deepen. The best part? It’s incredibly easy to pull off—just 35 minutes from start to finish.

This one-pan wonder is cozy enough for a chill night in, but elegant enough to serve when you’ve got company. I made it last week for dinner with my friend Jenna, and she legit asked for the recipe before we were even done eating. It’s that kind of dish—comforting, satisfying, and worthy of repeat requests.

Why You’ll Love This Recipe

Key Benefits

• Quick and simple: It’s ready in just 35 minutes—perfect for busy weeknights.
• Minimal cleanup: Everything happens in one skillet and then finishes in the oven.
• Impressive but easy: This looks and tastes like something from a restaurant, but it’s super beginner-friendly.
• Crowd-pleaser: Even picky eaters love the creamy, herby sauce.

Taste & Texture

You’ll get tender, juicy chicken with a lightly crisped exterior from the sear, then a creamy, garlicky pesto sauce that clings to every bite. The cherry tomatoes soften and burst, adding sweetness, while the olives and capers bring a briny contrast that cuts through the richness. It’s the perfect harmony of comfort and bold flavor.

Dietary Attributes

This dish is naturally gluten-free and can easily be adapted to suit lower-carb lifestyles. For a lighter version, you can use half-and-half or even evaporated milk instead of heavy cream.

Ingredients & Substitutions

Ingredient List

• 4 boneless, skinless chicken breast fillets
• Sea salt, to taste
• Freshly ground black pepper, to taste
• 2 ½ tablespoons olive oil
• 1 ½ cups heavy whipping cream
• 3 tablespoons butter
• 1 pinch garlic powder
• 1 pinch sea salt
• ½ cup basil pesto (homemade or store-bought)
• ¾ cup grated parmesan cheese
• 1 ½ cups cherry tomatoes
• ⅔ cup pitted Kalamata olives
• 2 ½ tablespoons non-pareil capers, rinsed
• Fresh basil leaves, hand-torn, for garnish

Notes on Quality

Use good-quality chicken breasts—air-chilled if possible—for the juiciest result. For the pesto, homemade is amazing (especially with garden-fresh basil), but there are also some fantastic store-bought options out there. Look for refrigerated pesto in the deli section for the freshest taste. Grate your parmesan fresh—pre-shredded just doesn’t melt the same.

Possible Substitutions

• Heavy cream: Sub with half-and-half or evaporated milk for a lighter version.
• Cherry tomatoes: Grape tomatoes or sun-dried tomatoes can also work.
• Kalamata olives: Swap with green olives if you prefer a sharper flavor.
• Butter: Ghee or dairy-free margarine can be used if you’re dairy-sensitive.

Step-by-Step Instructions

1. Preheat the oven to 400°F. Rinse and pat dry your chicken breasts with paper towels.
2. Season both sides of the chicken with sea salt and black pepper.
3. In a large cast-iron skillet, heat olive oil over medium. Sear the chicken for 4 minutes per side, until golden brown. Remove the pan from heat.
4. While the chicken is searing, warm the cream and butter in a small saucepan over medium-low heat. Don’t let it boil.
5. Stir in the garlic powder, salt, and basil pesto.
6. Grate the parmesan directly into the sauce, stirring with a wooden spoon until melted and combined.
7. Return the seared chicken to the skillet. Scatter the cherry tomatoes, olives, and capers on top.
8. Pour the creamy pesto sauce evenly over everything.
9. Bake uncovered for 20-25 minutes, until the internal temperature of the chicken reaches 165°F.
10. Garnish with hand-torn basil before serving.

Expert Tips & Tricks

Best Practices

• Sear the chicken well: A golden crust adds so much flavor.
• Use freshly grated parmesan: It melts smoother and tastes way better.
• Taste your pesto before using: Some store-bought versions can be saltier than others. Adjust salt in the sauce accordingly.

Common Mistakes

• Boiling the cream: Keep it at a gentle simmer to avoid breaking the sauce.
• Skipping the sear: It locks in juices and gives the chicken a better texture.
• Overbaking: Always use a meat thermometer to avoid dry chicken.

Time-Saving Tips

• Use pre-sliced or thin chicken cutlets to skip the searing step.
• Prep the sauce the night before and store in the fridge.
• Grab pre-grated cheese and jarred pesto for ultimate convenience.

Serving Suggestions

Pairings

This creamy pesto chicken is heavenly served over:

• Mashed potatoes
• Steamed white rice or wild rice
• Buttered noodles or fettuccine
• Cauliflower rice for a low-carb option

Presentation Ideas

Serve it straight from the skillet for a rustic, family-style dinner, or plate it individually with a drizzle of sauce and a few extra basil leaves on top for a more elegant look. A few extra cherry tomatoes on the side add a pop of color.

Beverage Pairings

• White wine: A chilled glass of Sauvignon Blanc or Chardonnay pairs beautifully.
• Cocktails: A cucumber gin and tonic or basil mojito is refreshing.
• Non-alcoholic: Sparkling water with lemon or an iced herbal tea is lovely and light.

Storage & Reheating

Leftover Storage

Store leftovers in an airtight container in the fridge for up to 3 days. The flavors deepen overnight, so it’s even better the next day.

Reheating Methods

• Reheat in a skillet over low heat with a splash of cream or broth to loosen the sauce.
• Microwave gently at 50% power in 1-minute intervals to avoid overcooking the chicken.

Frequently Asked Questions

Substitutions & Adjustments

Can I use chicken thighs instead of breasts?
Absolutely. Boneless, skinless thighs work beautifully and are even juicier.

What can I use instead of olives or capers?
Try chopped marinated artichokes or even a handful of spinach for a milder flavor.

Troubleshooting

My sauce broke—how can I fix it?
If your sauce separates, whisk in a tablespoon of cold cream off the heat until it comes back together.

My chicken came out dry—what went wrong?
It was likely overcooked. Always check the internal temp and pull the chicken as soon as it hits 165°F.

Variations & Customizations

Dietary Adaptations

• Keto: Swap the tomatoes for extra olives and reduce the capers slightly.
• Dairy-free: Use coconut cream and a dairy-free pesto alternative.
• Low-calorie: Use half-and-half instead of cream and reduce the amount of parmesan.

Flavor Twists

• Add sun-dried tomatoes or chopped spinach to the sauce.
• Stir in a teaspoon of red pepper flakes for a kick.
• Swap the basil pesto for sun-dried tomato pesto for a different vibe.

Seasonal/Holiday Versions

• In summer, top with fresh heirloom tomato slices and a little lemon zest.
• For the holidays, add roasted red peppers and serve over creamy polenta.
