Creamy Pesto Chicken with Roasted Tomatoes & Spinach

Creamy Pesto Chicken with Roasted Tomatoes & Spinach tastes rich, herby, and a little tangy, with juicy chicken and sweet, blistered tomatoes tucked into a silky sauce. It works perfectly for busy weeknights, date nights at home, or meal prep, and you can get it on the table in about 35 minutes. I first made a version of this in a tiny apartment kitchen with one skillet and a dream of not eating sad chicken again.

Why Creamy Pesto Chicken with Roasted Tomatoes & Spinach Is Worth It

This recipe gives you tender chicken, a lush pesto cream sauce, and roasted tomatoes that pop with sweetness in every bite. You toss in spinach at the end so it wilts into the sauce and makes the whole skillet look like it belongs on a magazine cover, but in a chill, weeknight way.

You cook everything in one pan plus a small sheet pan, so cleanup stays easy. The flavor feels restaurant-level, yet you use simple grocery store ingredients and a jar of pesto from your pantry shelf.

Ingredients You Need

Chicken and marinade

• 1.5 to 2 pounds boneless skinless chicken breasts
  • Slice large breasts horizontally into cutlets so they cook evenly.
• 1 tablespoon olive oil
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• ½ teaspoon garlic powder
• ½ teaspoon onion powder

Roasted tomatoes

• 1 pint cherry or grape tomatoes
• 1 tablespoon olive oil
• ¼ teaspoon kosher salt
• ¼ teaspoon black pepper
• Pinch of sugar, optional
  • Helps with extra tangy tomatoes.

Creamy pesto sauce

• 1 tablespoon butter
• 3 cloves garlic, minced
• 1 cup heavy cream
  • Use half and half for a lighter version, but the sauce thickens less.
• ½ cup chicken broth
  • Use low sodium so you control the salt.
• ½ to ⅔ cup basil pesto
  • Jarred pesto works great; look for brands with olive oil and real Parmesan.
• ¼ cup grated Parmesan cheese
• 2 cups fresh baby spinach, lightly packed
• ½ teaspoon Italian seasoning
• Juice of ½ lemon
• Extra salt and pepper to taste

Optional add ons

• Crushed red pepper flakes, to taste
• Extra Parmesan for serving
• Fresh basil, chopped, for garnish

Pantry shortcuts and notes

• Use jarred pesto from Costco, Trader Joe’s, or your favorite brand.
• Use pre-minced garlic from a jar if you need speed, though fresh garlic tastes brighter.
• Use bagged baby spinach so you skip trimming stems.

Equipment list

• Large skillet, preferably stainless steel or cast iron
• Small sheet pan or baking dish
• Cutting board and sharp knife
• Tongs or spatula
• Measuring cups and spoons
• Small whisk or wooden spoon

Quick Tips & substitutions

• Pound thick chicken breasts to an even thickness so they cook quickly and stay juicy.
• Dry the chicken with paper towels before seasoning so it browns better.
• Use chicken thighs instead of breasts if you like extra juicy meat; cook a few minutes longer.
• Swap heavy cream with full fat coconut milk for a dairy free option and use vegan pesto.
• Stir pesto into the sauce off the heat so it keeps a fresher basil flavor.
• Roast tomatoes while the chicken cooks so you save time.
• Use frozen spinach in a pinch; thaw, squeeze very dry, then stir in at the end.
• Taste the sauce before adding extra salt since pesto and Parmesan already bring saltiness.
• Thin a too-thick sauce with a splash of broth; simmer a few extra minutes if it feels too thin.
• Slice chicken against the grain before serving for tender bites every time.

How to Make Creamy Pesto Chicken with Roasted Tomatoes & Spinach

Step 1: Season the chicken

Pat the chicken dry and place it on a cutting board. Sprinkle both sides with salt, pepper, garlic powder, and onion powder. Drizzle with olive oil and rub the seasoning all over so it coats evenly.

Step 2: Roast the tomatoes

Preheat the oven to 400°F. Toss cherry tomatoes with olive oil, salt, pepper, and a pinch of sugar on a small sheet pan. Spread them in a single layer and roast 12 to 15 minutes until they wrinkle and some skins split.

Step 3: Sear the chicken

Heat a large skillet over medium high heat and add a drizzle of olive oil if the pan looks dry. Lay the chicken in the hot skillet and let it cook without moving it for 4 to 6 minutes on the first side, until it browns deeply. Flip and cook another 3 to 5 minutes, until the thickest part reaches 165°F.

Transfer the cooked chicken to a plate and tent loosely with foil to keep it warm. Do not wipe out the skillet; those browned bits on the bottom carry big flavor. Lower the heat to medium.

Step 4: Build the creamy pesto sauce

Add butter to the same skillet and let it melt. Stir in the minced garlic and cook about 30 seconds until it smells fragrant, not browned. Pour in the chicken broth and use a wooden spoon to scrape up the browned bits from the bottom of the pan.

Stir in the heavy cream and Italian seasoning. Let the mixture simmer gently for 3 to 5 minutes, stirring often, until it thickens slightly and coats the back of a spoon. Turn the heat to low, then stir in the Parmesan until it melts smoothly into the sauce.

Step 5: Add pesto and spinach

Take the skillet off the heat for a moment and stir in the pesto until the sauce turns a creamy green. Return the skillet to low heat and add the spinach. Stir until the spinach wilts into the sauce and softens, about 1 to 2 minutes.

Squeeze in the lemon juice and taste the sauce. Add a pinch of salt, pepper, or more pesto if you want a stronger basil flavor. If the sauce feels too thick, add a splash of broth or water and stir.

Step 6: Combine chicken and roasted tomatoes

Slice the rested chicken into strips or leave the pieces whole. Nestle the chicken into the skillet of creamy pesto sauce. Spoon sauce over the top so every piece gets coated.

Scatter the roasted tomatoes over the chicken and sauce. Let everything warm together on low heat for 2 to 3 minutes so the flavors mingle. Sprinkle with crushed red pepper flakes, extra Parmesan, or fresh basil if you like a little flourish.

Step 7: Serve

Serve Creamy Pesto Chicken with Roasted Tomatoes & Spinach hot from the skillet. Spoon extra sauce over each portion. Watch everyone quietly stop talking for a second while they take that first bite.
