01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Rinse and pat dry zucchini. Remove ends and slice each one lengthwise into quarters to create spears.
03 - Combine zucchini spears, olive oil, smoked paprika, garlic powder, sea salt, and black pepper in a large bowl. Toss thoroughly to coat each spear evenly.
04 - Spread spears on the prepared baking sheet in a single layer with skin side down.
05 - Roast for 18 to 20 minutes, or until spears are tender and edges turn golden brown.
06 - Transfer roasted zucchini to a platter. Scatter chopped parsley and lemon zest over the top before serving, if desired.
