Ingredients You’ll Need
Fresh ingredients
- 3 medium zucchini, thinly sliced into rounds or half moons
- Choose firm zucchini with shiny skin and no soft spots.
- 1 small yellow onion, thinly sliced
- 2 cloves garlic, minced
- 2 large eggs
- 1 cup shredded mozzarella cheese
- Low moisture, part skim works best and melts evenly.
- 1 cup shredded sharp cheddar cheese
- Sharp cheddar adds flavor so you can use less salt.
- 1 cup grated or finely shredded Parmesan cheese
- Use real Parmigiano Reggiano or a good domestic brand, not the green can.
Pantry ingredients
- 2 tablespoons olive oil
- 1 tablespoon butter, melted
- 1/2 cup panko breadcrumbs
- Regular or gluten free panko both work.
- 1/2 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1 teaspoon Italian seasoning
- Or a mix of dried oregano and basil.
- 1/4 teaspoon red pepper flakes (optional, for a little heat)
Optional add ins and substitutions
- Swap half the zucchini with yellow squash for more color.
- Use Monterey Jack or Colby Jack instead of cheddar for a milder flavor.
- Replace panko with crushed cornflakes or crushed plain crackers if you need a breadcrumb substitute.
- Add 1/4 cup finely chopped fresh herbs such as parsley or basil for a fresher flavor.
Equipment list
- 9×13 inch baking dish or similar casserole dish
- Large mixing bowl
- Sharp knife and cutting board
- Measuring cups and spoons
- Whisk or fork
- Aluminum foil
- Oven mitts
- Box grater or food processor with shredding blade if you grate your own cheese
Tips & Tricks
- Slice zucchini evenly so it cooks at the same rate and does not turn mushy.
- Pat zucchini slices dry with a paper towel to reduce extra moisture before mixing.
- Grate cheese from a block, since pre shredded cheese often contains starch that affects melting.
- Season the zucchini generously, because vegetables need more salt than you think.
- Mix a little Parmesan into the panko topping so it browns deeply and stays crisp.
- Bake uncovered at the end so the top turns golden and bubbly.
- Let the casserole rest 5 to 10 minutes before serving so it sets and slices cleanly.
- Use a hot oven, at least 400°F, to keep the zucchini tender but not watery.
How to Make Baked Zucchini and Cheese Recipe
Step 1: Prep the oven and pan
Preheat your oven to 400°F. Lightly grease a 9×13 inch baking dish with olive oil or a quick swipe of butter. Set the dish aside while you prep the vegetables and cheese.
Step 2: Slice and season the zucchini
Wash and dry the zucchini thoroughly. Slice each zucchini into thin rounds, about 1/4 inch thick, or cut lengthwise in half and then into half moons. Pat the slices dry with paper towels to remove surface moisture.
Place the zucchini in a large mixing bowl with the sliced onion and minced garlic. Drizzle with 2 tablespoons olive oil, then add salt, pepper, Italian seasoning, and red pepper flakes if you use them. Toss everything until the vegetables look evenly coated.
Step 3: Mix the cheesy base
Crack the eggs into a separate bowl and whisk until smooth. Add half of the mozzarella, half of the cheddar, and half of the Parmesan to the eggs. Stir until the cheese and eggs combine into a thick mixture.
Pour this cheesy egg mixture over the seasoned zucchini and onion. Toss again until every slice of zucchini carries some cheese and egg coating. This mixture will help the casserole set and hold together.
Step 4: Assemble in the baking dish
Spread the zucchini mixture evenly in the prepared baking dish. Press it down gently with a spatula so it forms an even layer. Sprinkle the remaining mozzarella, cheddar, and Parmesan over the top.
In a small bowl, mix the panko with the melted butter and a pinch of salt and pepper. Stir until the crumbs look lightly coated and clump a bit. Sprinkle this mixture evenly over the cheese layer.
Step 5: Bake until bubbly and golden
Place the baking dish on the middle rack of the oven. Bake for 25 to 30 minutes, until the zucchini turns tender and the cheese bubbles around the edges. If the top needs more color, switch to broil for 1 to 2 minutes and watch closely so it does not burn.
Remove the dish from the oven and set it on a heat safe surface. Let the baked zucchini and cheese rest for 5 to 10 minutes. Slice into squares or scoop with a large spoon and serve warm.
What to Serve with it?
This baked zucchini and cheese recipe pairs nicely with simple grilled chicken, roasted turkey breast, or baked fish. You can also serve it with a big green salad and some crusty garlic bread for a meatless dinner. Kids usually enjoy it with baked chicken tenders or turkey meatballs.
If you want more vegetables on the plate, add roasted carrots, steamed green beans, or a tomato cucumber salad. The cheesy zucchini also works well next to plain rice or quinoa, since the grains soak up the extra cheesy sauce.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
- Cool the casserole completely before covering so condensation does not make the topping soggy.
- Reheat individual portions in the microwave in 30 second bursts until hot, then finish under the broiler for 1 to 2 minutes to crisp the top.
- Reheat larger portions in a 350°F oven, covered with foil for 10 to 15 minutes, then uncover for 5 minutes.
- Freeze tightly wrapped portions for up to 2 months, then thaw overnight in the fridge before reheating in the oven.
