Hasselback Chicken Spinach Mozzarella

The first time I tried making those signature slices into chicken breast, my hands were literally shaking. One wrong move and you've got butterflied meat instead of that gorgeous fan effect everyone posts on Instagram. But honestly, even my slightly messy first attempt looked impressive coming out of the oven. Now it's become my go-to when I want to make something that looks like I spent hours at the stove.

Last winter, my sister came over for what was supposed to be a quick catch-up dinner. I pulled this chicken out of the oven, all golden and bubbling, and she actually paused mid-sentence to take a photo. We spent the whole meal picking apart different ways to customize the filling, her adding notes in her phone between bites. That's when I knew this wasn't just a recipe, it was a conversation starter.

Ingredients

• 4 boneless, skinless chicken breasts: Go for breasts that are fairly even in thickness so they cook at the same rate
• 100 g baby spinach, washed: Fresh spinach wilts beautifully into the cheese mixture without adding excess moisture
• 100 g mozzarella cheese, shredded: The melt factor here is crucial, freshly grated gives you way better results than pre-shredded
• 60 g sun-dried tomatoes, drained and chopped: These pack an umami punch that balances the mild chicken and creamy cheese
• 2 cloves garlic, minced: Fresh garlic beats garlic powder every single time in this filling
• 2 tbsp olive oil: Helps the seasoning cling and keeps everything from drying out in the oven
• 1 tsp dried Italian herbs: Classic herbs that complement everything else without overpowering
• ½ tsp paprika: Adds a subtle warmth and gorgeous color to the finished dish
• Salt and freshly ground black pepper: Season generously, chicken needs proper salting to shine

Instructions

Get your oven ready:

Preheat to 200°C (390°F) so you're not waiting around once the chicken is prepped

Create those signature slices:

Using your sharpest knife, make cuts about 1 cm apart across each chicken breast, stopping before you cut all the way through

Mix up your filling:

Combine the mozzarella, spinach, sun-dried tomatoes and garlic in a bowl until everything is evenly distributed

Stuff the chicken:

Gently press the filling into each cut, really getting it into those crevices you just created

Season and arrange:

Place the chicken in a baking dish, drizzle with olive oil and sprinkle with Italian herbs, paprika, salt and pepper

Bake to perfection:

Pop it in the oven for 25 to 30 minutes until the chicken is cooked through and the filling is bubbly and golden

Let it rest:

Give the chicken about 5 minutes to rest before serving, this keeps everything juicy

My husband claimed he wasn't hungry when I made this for the first time on a random Tuesday night. He went back for seconds and then literally licked his fork clean. Now it's his most requested meal, and he doesn't even care that it takes a few extra minutes of prep work.

Making It Your Own

Once you get the basic slicing technique down, the filling variations are endless. I've swapped mozzarella for fontina when I wanted something more nutty, and used fresh basil instead of spinach in the summer. The sun-dried tomatoes are non-negotiable for me though, that tangy sweetness is what ties everything together.

Serving Suggestions That Work

Roasted vegetables with a little char from the oven complement this perfectly. A crisp green salad with an acidic vinaigrette cuts through the richness. And honestly, some crusty bread to soak up any escaped cheese is never a bad idea.

Timing And Prep

The hands-on time is about 20 minutes, mostly spent on the careful slicing work. While the oven does its thing for half an hour, you've got time to clean up and pull together sides. The resting period is crucial, so don't skip those five minutes.

• Everything can be prepped up to the baking point several hours ahead
• The filling gets better if it sits for a bit, so mix it early if you can
• Leftovers reheat surprisingly well in the oven the next day

There's something deeply satisfying about cutting into that first slice and seeing all those layers of cheese and tomato. It's the kind of dish that makes you feel accomplished without actually being difficult.

Recipe Questions & Answers

→ What is Hasselback chicken?

Hasselback chicken features boneless breasts sliced in thin, even rows without cutting all the way through. Each slit gets stuffed with flavorful fillings, creating a visually impressive presentation that allows seasonings and cheese to melt into every layer while baking.

→ How do I prevent the chicken from drying out?

The key is making thin, even slices and generously stuffing each cut with the cheese and spinach mixture. The mozzarella releases moisture during baking, keeping the meat tender. Basting with olive oil before baking also helps maintain juiciness throughout the cooking process.

→ Can I prepare this dish ahead of time?

Absolutely. You can slice and stuff the chicken up to 24 hours in advance, then store it covered in the refrigerator. When ready to bake, simply drizzle with olive oil and seasonings before placing in the oven. The flavors actually develop more depth with this overnight resting period.

→ What vegetables pair well with this dish?

Roasted vegetables like zucchini, bell peppers, or asparagus complement the flavors beautifully. A fresh green salad with vinaigrette provides a bright contrast to the rich, cheesy stuffing. For a heartier meal, serve alongside roasted potatoes or cauliflower rice.

→ 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 inserted into the thickest part. Visual cues include the cheese turning golden and bubbly, and the meat feeling firm rather than squishy when gently pressed. Letting it rest for 5 minutes after baking ensures juices redistribute throughout.

→ Can I use different fillings?

Certainly. Try swapping mozzarella for feta or goat cheese, adding cooked bacon or pancetta, incorporating fresh basil or sun-dried tomato pesto, or using different vegetables like roasted red peppers or artichoke hearts. The Hasselback technique works wonderfully with various flavor combinations.
