Gooey mozzarella and juicy chicken unite in this mouthwatering Cheesy Mozzarella Chicken Bake. When vibrant tomato sauce meets melty cheese, you'll get a fancy-looking dinner that's actually super easy to whip up at home. It turns basic chicken into something that'll make your family think you've been taking secret cooking classes.
I threw this dish together one stormy weekend afternoon, and the smell of herbs and garlic made the whole house feel cozy. My kids kept wandering into the kitchen asking when dinner would be ready, and now they beg for it whenever comfort food is needed.
Key Ingredients
- Boneless, skinless chicken breasts: Try to grab ones that are about the same thickness so they cook evenly. Good ones should look bright pink without any funky brown areas
- Fresh mozzarella: This is what gives you that Instagram-worthy cheese pull. Let it sit out for a bit before using so it melts better
- Crushed tomatoes: If you can find San Marzano ones, they're worth the extra cost—they've got the perfect sweet-tangy balance
- Fresh garlic: Skip the jar stuff! Real garlic cloves make everything taste so much better
- Italian seasoning blend: This handy mix saves you from digging through your spice cabinet for five different herbs
- Extra virgin olive oil: Don't cheap out here—a good one adds amazing flavor that really makes the Mediterranean vibe pop
Detailed Cooking Instructions
- Step 1: Prepare the chicken
- Grab some paper towels and really dry those chicken breasts off completely
- Don't be shy with the salt and pepper—coat both sides well and press it in with your fingers
- Let the chicken hang out on the counter for about 15 minutes so it cooks more evenly later
- Step 2: Create the sauce base
- Get your olive oil nice and hot until you see that shimmery look
- Toss in your minced garlic and keep it moving so it doesn't burn
- Pour your crushed tomatoes in slowly or you'll end up wearing your dinner
- Give it time to bubble away and thicken up, stirring every now and then
- Step 3: Assemble the dish
- Put just a bit of sauce across the bottom of your baking dish
- Place your chicken pieces down with some breathing room between them
- Pour the rest of your sauce around the chicken, not directly on top
- Cover each piece with slices of that lovely mozzarella
- Step 4: Perfect the bake
- Stick it in your already hot oven, right on the middle rack
- Let it cook uncovered until that cheese gets all bubbly and golden
- Once it's done, be patient for 5-7 minutes before digging in so the juices settle down

I come from an Italian-American family where cheese quality was practically a religion. My grandma wouldn't even consider using anything but fresh mozzarella from Mr. Rossi at the neighborhood deli. I can still picture her face lighting up at that perfect stretch of cheese when she pulled her fork away from the plate.
Prep In Advance
You can make the sauce up to three days before you need it, and honestly, it gets even tastier as it sits. Just keep it in a sealed container in your fridge and warm it up gently before you put everything together.
Serving Suggestions
This chicken goes great with some garlicky roasted broccoli or a simple Caesar salad with crunchy croutons. If you're extra hungry, toss it on top of some pasta to soak up all that amazing sauce. And don't forget to grab some crusty bread to wipe your plate clean afterward.
Wine Pairing
Grab a bottle of Chianti to drink with this. Its tanginess works really well with the tomato sauce while still standing up to all that rich, melty cheese.

I've tweaked this dish over and over through the years, and I've learned it's those small things that make it extra good. Don't rush the sauce. Let that cheese get perfectly golden on top. Sometimes the simplest food made with a little patience turns into the meals your family talks about for years.
