Ingredients You’ll Need
Here’s everything to gather for this summer staple:
- 2 medium zucchini, sliced into half-moons
- 2 medium yellow squash, sliced into half-moons
- 4 tbsp chopped fresh basil
- 2 tbsp thinly sliced green onion
- ½ tsp dried thyme
- ¾ tsp garlic powder
- 1 cup grated mozzarella (divided)
- ½ cup coarsely grated Parmesan (plus extra for topping, optional)
- Salt & black pepper to taste
Optional swaps:
- Sub in fresh oregano or parsley for basil
- Use low-fat cheese for a lighter twist
- Add red pepper flakes for a tiny kick
Best Cheese Options
Stick with melty white cheeses! Fontina, Monterey Jack, or Gruyère melt beautifully and add deeper flavor. Just be mindful of saltiness if you swap Parmesan for something stronger like Asiago.
How to Make Easy Cheesy Zucchini Bake

Step 1 – Prep the Veggies
Preheat oven to 350°F (180°C). Lightly oil an 8×8″ or 8×11″ baking dish. Slice your zucchini and yellow squash into half-moons (not too thin, so they hold shape). Chop your basil and green onions.
Step 2 – Toss with Seasonings and Cheese
In a large bowl, toss the squash with basil, onions, thyme, garlic powder, ½ cup mozzarella, and all the Parmesan. Season generously with salt and pepper. Mix it well so everything’s coated in cheesy goodness.
Step 3 – Bake, Top, and Bake Again
Spread the mixture evenly in your dish. Bake uncovered for 25–30 minutes until squash starts to soften. Remove, sprinkle the rest of the mozzarella and extra Parmesan on top, and return to the oven for 10–15 more minutes, until bubbling and golden brown.
Serve hot and let the cheese pull speak for itself.
Make It Low-Carb or Keto-Friendly
This bake is already low-carb, but if you want to turn it into a full keto meal, pair it with:
- Grilled sausage
- Roasted chicken thighs
- Beef kabobs or steak bites
You’ll get a satisfying, hearty plate without piling on carbs.
Storage and Reheating Tips
- Store leftovers in an airtight container in the fridge for up to 3 days
- Reheat in a toaster oven or microwave (but the oven keeps it crispier!)
- Great for lunch meal prep or an easy dinner side the next day

FAQs
Can I freeze this zucchini bake?
Not recommended. Zucchini holds a lot of water and can get mushy after freezing. For best texture, store in the fridge and enjoy within a few days.
Do I need to salt and drain the zucchini first?
Nope! As long as you don’t slice the squash too thin and bake uncovered, the texture holds up well without that extra step.
Can I make this dairy-free?
Totally. Use dairy-free mozzarella and Parmesan alternatives that melt well, like the ones from Miyoko’s or Violife.
If you’ve got a pile of summer squash and a block of cheese — you’ve got dinner. 🧀🌿 This Easy Cheesy Zucchini Bake is ready when you are. Let me know if you try it, or snap a photo and tag @elyrecipes on Pinterest or Facebook !Print
