What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any fuss. Here’s what you’ll need:

• Fresh zucchini: Medium-sized works best for even roasting.
• Yellow squash: Adds a pop of color and a slightly different flavor.
• Olive oil: Extra virgin olive oil for rich, savory flavor.
• Salt: Kosher salt or sea salt to enhance the zucchini’s natural sweetness.
• Black pepper: Freshly ground for a subtle kick.
• Garlic powder: Optional but highly recommended for a hint of savory depth.
• Italian seasoning: Or swap it with thyme, rosemary, or parsley for a different flavor profile.
• Parmesan cheese: Optional topping for extra indulgence.

If you’re missing an ingredient, don’t worry—this recipe is incredibly forgiving. You can substitute yellow squash with more zucchini or swap olive oil for avocado oil. Want to make it dairy-free? Skip the Parmesan or use nutritional yeast instead.

Equipment Needed

You don’t need fancy gadgets to make this roasted zucchini recipe, but a few tools will help make the process smoother:

• Baking sheet: A large, rimmed sheet works best to prevent overcrowding.
• Chef’s knife: For slicing the zucchini evenly.
• Cutting board: A sturdy surface for prepping your veggies.
• Mixing bowl: For tossing the zucchini with olive oil and seasoning.
• Spatula or tongs: To flip the zucchini halfway through roasting.

If you don’t have a baking sheet, you can use a large oven-safe dish instead. Just make sure the zucchini isn’t stacked—spread it out in a single layer for even cooking.

Preparation Method

1. Preheat your oven: Set it to 425°F (220°C). A hotter oven ensures those delicious caramelized edges.
2. Prep the zucchini: Wash and dry the zucchini and squash. Slice them into even rounds or half-moons, about ¼-inch thick.
3. Toss with seasoning: In a large bowl, combine the zucchini slices, olive oil, salt, pepper, garlic powder, and Italian seasoning. Mix until evenly coated.
4. Arrange on a baking sheet: Spread the zucchini in a single layer on the sheet, leaving space between each piece for proper roasting.
5. Roast: Bake for 15 minutes, then flip the zucchini using a spatula or tongs. Roast for another 10-15 minutes until golden brown and tender.
6. Optional topping: Sprinkle with Parmesan cheese during the last 5 minutes for a gooey, golden finish.
7. Serve: Transfer to a serving plate and enjoy hot, warm, or at room temperature.

Pro tip: If your zucchini comes out too soft, it’s likely because it was crowded on the baking sheet or sliced too thin. Spread it out and aim for consistent thickness to avoid soggy pieces.

Cooking Tips & Techniques

• Uniform slicing: Even sizes ensure all pieces cook at the same rate.
• Don’t overcrowd: If the zucchini is piled up, it’ll steam instead of roast. Use two baking sheets if needed.
• High heat is key: Roasting at 425°F caramelizes the natural sugars for the best flavor.
• Flip halfway: Turning the zucchini ensures both sides get evenly browned.
• Experiment with spices: Try smoked paprika, cumin, or chili powder for a fun twist.

One mistake I made early on was slicing the zucchini too thin—it turned out mushy instead of tender. Learn from my experience and aim for that sweet spot of ¼-inch thickness!

Variations & Adaptations

• Low-carb version: Skip the Parmesan cheese and use a sprinkle of nutritional yeast for a dairy-free option.
• Summer twist: Add fresh cherry tomatoes or bell peppers to the baking sheet for a colorful veggie medley.
• Spicy kick: Toss the zucchini with red pepper flakes or a dash of cayenne for heat lovers.
• Air fryer adaptation: Roast the zucchini in an air fryer at 400°F for 10-12 minutes, shaking halfway through.
• Herb swap: Replace Italian seasoning with fresh dill or cilantro for a fresh flavor profile.

One of my favorite variations is adding sliced onions to the mix—they caramelize beautifully alongside the zucchini and squash!

Serving & Storage Suggestions

This roasted zucchini recipe is best served warm, straight from the oven, but it’s also delicious at room temperature. Here are some ideas:

• Serving: Pair with grilled chicken, fish, or steak for a complete meal. Alternatively, serve over rice or quinoa for a vegetarian option.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
• Reheating: Reheat in the oven at 375°F or in a skillet over medium heat for crispy edges.
• Freezer-friendly: Freeze roasted zucchini in a single layer, then transfer to a freezer bag for up to 2 months. Reheat directly from frozen.

The flavors deepen as the zucchini sits, so it’s perfect for meal prep or make-ahead dinners.
