Ingredients
Gather ’round, these are kitchen staples for a reason!
- 2 large zucchini: Look for firm, vibrant green ones.
- 2 large yellow squash: These add such a beautiful pop of color! Like little rays of sunshine.
- 2 tsp garlic powder: This gives us that classic roasted veggie flavor without mincing fresh garlic (keeping it simple!).
- 1/2 tsp ground black pepper: Freshly ground is always lovely, but pre-ground is perfectly fine here.
- 1/2 tsp salt, or to taste: Start with this, you can always add a pinch more after roasting if needed.
- 1/4 cup grated or shredded parmesan cheese: This is the magic dust! It gets delightfully toasty in the oven. Use good quality stuff if you can!
- 2 tbsp olive oil: Just enough to coat everything and help those edges crisp up.
How to Make It
Okay, let’s get these beauties roasted! It’s ridiculously simple, I promise.
1. Get your oven ready. Preheat your oven to a nice hot 400°F (200°C). This high temp is key to getting them tender quickly without getting mushy.
2. Slice and dice (well, slice!). Wash your zucchini and yellow squash. Trim off the ends. Now, slice them into rounds about 1/4 inch thick. Try to keep them relatively uniform so they cook at the same rate. You want them substantial enough not to fall apart, but not too thick that they take forever.
3. Toss everything together. Grab a large bowl – big enough to hold all those lovely slices. Add your sliced squash and zucchini. Drizzle the olive oil over them, then sprinkle with the garlic powder and pepper. Now, give everything a good toss with your hands or a spatula until every piece is nicely coated in that delicious oil and seasoning mix. I like to use my hands; it feels more connected to the food!
4. Spread ’em out. This step is crucial for success! Arrange the coated squash and zucchini in a single layer on a baking pan. Don’t overcrowd the pan! If they’re piled on top of each other, they’ll steam instead of roast, and you’ll miss out on those lovely slightly crispy edges. Use two pans if you need to.
5. Sprinkle the cheese. Now for the cheesy goodness! Sprinkle the grated or shredded parmesan evenly over the single layer of squash. Don’t be shy!
6. Roast time! Pop the pan into your preheated oven. Roast for about 9-10 minutes. You’re looking for them to be tender when you pierce them gently with a fork.
7. Get that golden finish. Here’s where the magic happens! Turn your oven’s broiler to high. Move the baking pan to the top oven rack (usually 4-6 inches from the heat). Broil for just 2-3 minutes. Watch it like a hawk! Broilers work fast, and cheese can go from perfectly golden to burnt in seconds. You want those little brown spots and slightly crispy edges. As soon as they look good, pull them out immediately.
Serve these roasted beauties right away! They are best hot out of the oven.

Substitutions & Additions
Want to mix things up? This recipe is super flexible!
- Herbs: Add dried Italian seasoning, dried oregano, or dried thyme along with the other seasonings. A sprinkle of fresh basil or parsley after roasting is also fantastic.
- Spices: A pinch of smoked paprika or a tiny pinch of red pepper flakes can add a lovely warmth or subtle kick.
- Other Veggies: Thinly sliced onions, bell peppers, or cherry tomatoes can be roasted alongside the squash.
- Different Cheese: Feta cheese crumbles, goat cheese, or even a dairy-free parmesan alternative would work well.
- Make it Vegan/Dairy-Free: Simply omit the parmesan cheese. They’ll still be delicious roasted with just the oil and seasonings!
Tips for Success
Just a couple of things to keep in mind to make sure your roasted squash is perfect every time.
- Don’t Overcrowd the Pan: I know I mentioned it in the steps, but it’s the number one mistake! Give those veggies space to breathe and roast.
- Uniform Slices: Try to make your slices roughly the same thickness so everything cooks evenly.
- Watch the Broiler Closely: Seriously, stay by the oven during the broiling step. It happens fast!
- Patting Dry (Optional but helpful): If your squash seems particularly wet after slicing, you can lightly blot the rounds with a paper towel before tossing with oil. This helps them roast rather than steam.
How to Store It
While these are definitely best enjoyed fresh, you might have leftovers!
Let them cool completely, then store them in an airtight container in the refrigerator for 3-4 days. To reheat, you can gently warm them in the microwave, but for the best texture, spread them on a baking sheet and warm in a preheated oven (around 350°F/175°C) for a few minutes until heated through. The microwave can sometimes make them a little soft.
FAQs
Got questions? I’ve got some answers!
### Can I use less oil?
You can slightly reduce the oil, but using 2 tablespoons helps ensure the seasonings stick and gives the veggies a better chance of roasting and getting those nice edges without drying out. It’s a small amount spread over a lot of veggies!
### Why do you broil them at the end?
Broiling gives them that last kiss of high heat right on top. It helps brown the cheese and get those slightly crispy, caramelized edges on the squash that are just divine!
### Can I skip the broiling step?
Yes, absolutely! They will still be tender and delicious roasted, but you’ll miss out on the browned cheese and crispy bits. If you’re short on time or just prefer them softer, you can skip it and just roast until tender.
