Hasselback Chicken Stuffed with Spinach

The first time I made Hasselback chicken, my husband walked into the kitchen and asked what on earth I was doing to those poor chicken breasts. But when it came out of the oven, all golden and oozing cheese in every little slice, he completely understood the method to my madness.

I served this at a dinner party last fall when my friend Sarah was visiting from out of town. She took one bite, put down her fork, and made me promise to text her the recipe right then and there before she forgot how incredible it was.

Ingredients

• 4 boneless skinless chicken breasts: The slicing technique works best when breasts are evenly thickened with a meat mallet first
• 100 g baby spinach: Fresh spinach wilts beautifully into the slices, avoiding the waterlog that frozen spinach would cause
• 100 g mozzarella cheese: Shred it yourself if possible, it melts better than pre-shredded which has anti-caking agents
• 60 g sun-dried tomatoes: The oil packed ones give more flavor than dry, but drain them well so they do not make the filling too wet
• 2 cloves garlic: Minced fresh garlic adds punch that perfectly balances the rich cheese and sweet tomatoes
• 2 tbsp olive oil: This helps the seasonings stick and keeps the chicken moist as it bakes
• 1 tsp dried Italian herbs: A classic blend works, but sometimes I use just oregano and basil for a simpler profile
• ½ tsp paprika: Adds a subtle warmth and gorgeous reddish color to the finished dish

Instructions

Prep and slice the chicken:

Preheat your oven to 200°C and pound each chicken breast to even thickness, then use a sharp knife to make slices about 1 cm apart, cutting three-quarters of the way through but leaving the bottom intact so each breast stays connected.

Make the filling mixture:

Combine the shredded mozzarella, washed spinach, chopped sun-dried tomatoes, and minced garlic in a bowl, mashing slightly with a fork to help the ingredients cling together when you stuff them.

Stuff and season:

Gently press small amounts of the filling into each slice, letting it mound slightly on top, then place in a baking dish and drizzle with olive oil before sprinkling with Italian herbs, paprika, salt, and pepper.

Bake to perfection:

Bake for 25 to 30 minutes until the chicken is cooked through and the cheese is golden and bubbly, then let rest for 5 minutes to let the juices redistribute before serving.

This dish became my go-to for impressing dinner guests without spending hours in the kitchen. There is something so satisfying about watching people discover all those little pockets of flavor.

Getting Those Perfect Slices

A sharp knife is absolutely critical here, I learned this the hard way when I tried using a slightly dull blade and ended up with jagged, uneven cuts. Take your time and let the knife do the work rather than forcing it through the meat.

Make It Your Own

Sometimes I swap mozzarella for gruyère when I want something sharper and more sophisticated. The combination with sun-dried tomatoes creates this amazing sweet and salty profile that feels restaurant quality.

What To Serve With Hasselback Chicken

A crisp green salad with a bright vinaigrette cuts through all that rich cheese beautifully. Roasted vegetables like asparagus or zucchini also work wonderfully since they can roast right alongside the chicken in the same oven.

• Cauliflower rice makes a great low carb base that soaks up all those flavorful juices
• A glass of Sauvignon Blanc complements the sundried tomatoes perfectly
• Save any leftover filling and mix it into scrambled eggs the next morning

There is nothing quite like pulling this dish out of the oven and watching everyone lean in a little closer. Enjoy every impressive, delicious bite.

Recipe FAQs

→ What makes hasselback chicken special?

The unique slicing technique creates pockets that allow the cheesy filling to melt into every cut, ensuring each bite is packed with flavor while keeping the meat incredibly moist and tender throughout cooking.

→ How do I prevent cutting all the way through the chicken?

Use a sharp knife and place a chopstick or wooden spoon handle underneath each breast as a guide. This stops the blade from cutting completely through while creating evenly spaced slices.

→ Can I prepare this dish ahead of time?

Yes, you can slice and stuff the chicken up to 24 hours in advance. Store covered in the refrigerator and bake when ready, adding an extra 5-10 minutes to cooking time if chilled.

→ What vegetables pair well with this chicken?

Roasted vegetables like zucchini, bell peppers, or asparagus complement this dish beautifully. Fresh green salads with light vinaigrette also provide a crisp contrast to the rich, cheesy filling.

→ Can I use different cheese in the filling?

Absolutely. While mozzarella provides excellent melting properties, try cheddar for sharpness, gruyère for nuttiness, or feta for a tangy Mediterranean twist that pairs wonderfully with sundried tomatoes.

→ How do I know when the chicken is fully cooked?

The internal temperature should reach 74°C (165°F) when measured with a meat thermometer. The juices should run clear, and the meat should feel firm rather than squishy when pressed.
