How to Make Crispy Roasted Zucchini, Squash & Tomatoes
1. Preheat & Prep
Preheat your oven to 425°F (220°C). High heat is the secret to getting crispy roasted vegetables instead of soggy ones. Line a large baking sheet with parchment paper or lightly grease it.
2. Season the Vegetables
In a large mixing bowl, combine zucchini, squash, and tomatoes. Drizzle with olive oil and add garlic, salt, pepper, Italian seasoning, and red pepper flakes. Toss until everything is evenly coated.
3. Arrange for Maximum Crispiness
Spread the vegetables in a single layer on the baking sheet. Avoid overcrowding—this allows moisture to escape and helps the veggies roast instead of steam.
4. Roast to Perfection
Roast for 20 minutes, then remove from the oven and gently flip the vegetables. Sprinkle Parmesan evenly over the top and return to the oven for another 10–15 minutes, or until the cheese is melted, golden, and slightly crispy.
5. Finish & Serve
Remove from the oven and garnish with fresh herbs if desired. Serve immediately for best texture.
Pro Tips for Extra Crispy Vegetables
-
Pat vegetables dry before seasoning to remove excess moisture
-
Use freshly grated Parmesan (pre-shredded won’t crisp as well)
-
Roast on the middle or upper rack for better browning
-
Don’t skip flipping halfway through cooking
Serving Ideas
This dish is incredibly versatile and works well with:
-
Grilled chicken or salmon for a healthy dinner

Storage & Meal Prep Tips
-
Store leftovers in an airtight container in the refrigerator for up to 4 days
-
Reheat in the oven or air fryer to restore crispiness
-
Avoid microwaving if you want to keep the vegetables crispy
