Wholesome Ingredients for This Roasted Zucchini and Corn

High-quality, simple ingredients make all the difference in this healthy zucchini corn side dish. Here are the nutritional stars of the recipe:

Zucchini: A fiber-rich, low-calorie vegetable loaded with vitamin C, potassium, and antioxidants. For an extra nutrient boost, leave the peel on when slicing.
Corn: Sweet and satisfying, corn brings natural carbohydrates and is a rich source of B vitamins and iron. Fresh or frozen corn works equally well—just make sure it’s thawed!

Parmesan Cheese: Just a sprinkle of cheese ties everything together with its nutty, salty notes. For a dairy-free option, try nutritional yeast instead.

Ingredients for Roasted Zucchini and Corn

2 medium zucchini, sliced into rounds
2 ears corn, kernels removed (or 2 cups of canned, or frozen corn, thawed)
2 tablespoons olive oil
½ teaspoon garlic powder
½ teaspoon paprika
½ teaspoon kosher salt
¼ teaspoon pepper
¼ cup (25 g) grated parmesan cheese
Parsley, chopped for garnish

How to Make Roasted Zucchini and Corn

Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the zucchini rounds and corn kernels.
Drizzle olive oil over the vegetables and toss until evenly coated.
Sprinkle garlic powder, paprika, kosher salt, and pepper onto the mixture. Toss to coat the veggies thoroughly in spices.
Spread the zucchini and corn on the prepared baking sheet in a single layer.
Roast for 20-22 minutes, then flip the zucchini slices and roast another 5 minutes until tender and slightly caramelized.
Sprinkle parmesan cheese over the vegetables and return to the oven for 3 minutes to melt the cheese.
Optional: Broil for 1-2 minutes to achieve a golden, crisp finishing layer. Watch closely to prevent burning!
Garnish with fresh parsley and serve warm.

How to Customize This Roasted Zucchini and Corn for Your Diet

Vegan: Swap parmesan cheese with nutritional yeast for the same umami boost.
Gluten-Free: This recipe is naturally free of gluten, making it perfect for those avoiding wheat.
Keto-Friendly: Reduce the corn quantity by half, as it is higher in carbs, and add extra zucchini instead.
Low-Sodium: Use half the kosher salt or omit it entirely—fresh herbs like parsley amp up flavor without the need for salt.
