Cozy Baked Zucchini and Cheese

As seen in Perfect Companions for Any Meal.

You’ll toss onions, green peppers, tomatoes, and zucchini in plenty of olive oil with some Italian herbs. Stack the veggies with lots of mozzarella. Pop it in the oven until the top bubbles and turns golden. When it comes out, throw on some fresh parsley and a pinch of chili flakes for a kick. It comes out all melty, warm, and easy to scoop—perfect with anything from a backyard BBQ to a big Sunday roast. Feels special, but you can toss it together early and swap any veggies or cheese you like.

When you fix zucchini and cheese in the oven, you get super cozy vibes and loads of flavor. The green squash softens up, all the colors look awesome, and gooey mozzarella takes it over the top. It feels like summer, but honestly, I toss this together any time I spot good zucchini at the market. Even folks who say they can't stand veggies always want seconds.

My daughter swore she wasn't a fan of zucchini, but the first time I served this, the gooey cheese grabbed her. She took one bite, grinned, then happily loaded her plate a second time.

Tasty Ingredients

  • Crushed red chili pepper flakes: Kick up the heat, but only if you dig a spicy twist
  • Fresh parsley: Tossed on last, it adds a cool pop and fresh look
  • Mozzarella cheese: Go for full fat and grate it yourself if you can, so you get that epic melt Pre-grated is fine in a crunch
  • Freshly cracked black pepper: Fresh cracks have a punch—makes everything taste a notch brighter
  • Salt: Makes those greens taste even more like themselves
  • Italian seasoning: It’s all the classic Italian herbs in one go—grab a fresh blend if you’ve got it
  • Garlic powder: Quick and effortless, coats all the veggies just right
  • Olive oil: Helps everything roast up golden and gives it shine and some body
  • Grape tomatoes: Sliced little tomatoes give sweet pops of flavor and brighten the whole pan
  • Onion: White or yellow—just grab what's handy for a nice base flavor
  • Green bell pepper: Adds sweet crunch—make sure it’s bright and firm
  • Zucchini: Grab ones that feel heavy and look fresh—this is the hero of it all

Easy Step-by-Step

Garnish and Serve:
Once the pan comes out, let everything chill for just a bit. Scatter parsley and a shake of chili flakes on top. Scoop it up while still warm and watch the cheesy strings stretch.
Final Bake:
Pop the dish back in for 10 more minutes. Wait for the cheese to turn bubbly and start getting golden around the sides. You want the veggies super tender underneath that cheesy layer.
Add Remaining Cheese:
Carefully sprinkle the rest of the mozzarella over the veggies. Don’t rush—taking a sec now means you get the chewy, dreamy finish on top.
Initial Bake:
Slide your dish into the hot oven for 20 minutes. The squash should be soft but still holding its shape, and all the flavors start mingling together.
Transfer to Baking Dish:
Tumble everything into a 9 by 13 pan. Spread it out flat. This is key for roasting and for getting a nice, cheesy finish later.
Add Cheese:
Add half the shredded mozzarella right to the veggie bowl. Mix it up so cheese melts into every bite and doesn’t just sit on top.
Season the Veggies:
Pour olive oil over the veggies and shake on the seasonings and pepper. Give it all a big stir so everything gets slicked up and seasoned on all sides.
Prepare the Vegetables:
Chop your zucchini and pepper into chunks, dice up onion nice and fine, halve all those little tomatoes, and toss everything into a big bowl.
Preheat the Oven:
Fire up your oven to 375 degrees F (190 C). Put the rack smack in the middle so things roast just right.

Nothing tops the magic of mozzarella here. Tried cheddar as an experiment, but it never melts the same. The whole family ends up reaching for that last cheesy bit every time. Honestly, it’s a highlight at dinner.

Leftover Tips

Keep any extras in a sealed container in the fridge and it stays fresh for three days. Heat it up in the oven or toaster oven to keep things gooey and prevent mushiness. Sure, you can nuke it for speed, but gentle reheating keeps it tasting best.

Swapping Ingredients

If yellow squash is what you’ve got, use it instead—works great. No green pepper? Red or orange ones bring extra sweetness. Out of mozzarella? Try Monterey Jack or provolone, but leave the hard cheeses like parmesan for another day—melty gooeyness is what makes this shine.

How To Serve

Pair this with chicken or fish off the grill for a full meal. Spoon it next to your favorite pasta or heap it on toasted bread slices to soak up every bit of cheesy goodness. Shows off at summer cookouts and potlucks too!

Common Recipe Questions

→ How can I keep zucchini from making the dish soggy?

Chop up your zucchini and blot it dry before you mix. Try not to cook it too long or it'll let out more water. Sprinkle a bit of salt, dab with a paper towel, and you're good.

→ Are different cheeses okay to use?

Absolutely! Swap in cheddar, provolone, or even Monterey Jack if you want a different melty bite.

→ Should I peel the skin off the zucchini first?

Don’t worry about peeling—zucchini skin gives extra color, flavor, and is good for you. Just scrub it and chop. Peel if you want, but it’s totally up to you.

→ What's the best way to save leftovers?

Let everything cool down, put it in a sealed container, and stash it in the fridge for three days. Warm it up slow for best results.

→ Can I get everything ready in advance?

You bet. Build the casserole, hold off on the last cheese, cover, and chill. Top with cheese and bake fresh when you want to serve.

→ What goes well with this baked veggie dish?

Tastes great next to roasted chicken, grilled steaks, or just a slice of fresh bread. It's a winner for Mediterranean-style or Italian meals too.
