How to make this recipe

This roasted zucchini and mushrooms recipe is straightforward and forgiving. You can prep the vegetables in advance and toss them with oil and herbs just before roasting. Only a few ingredients are needed to create a flavorful vegetable side.

Pro tip: Cut the zucchini and mushrooms into uniform pieces to ensure even cooking and consistent caramelization.

1. Preheat oven to 400°F (200°C). In a large rimmed baking sheet, combine the zucchini and mushrooms. Drizzle with olive oil, add the thyme, and season with salt and pepper. Toss until everything is evenly coated.
2. Roast for 20–25 minutes, stirring once or twice if desired, until the vegetables are tender and nicely caramelized at the edges. Serve immediately.

Serving suggestions

These roasted zucchini and mushrooms pair well with many main dishes. Try them with:

• Air fryer chicken breast
• Lemon Dijon baked salmon
• Pan-seared steak
• Grains such as quinoa, farro, or rice for a complete vegetarian meal

Recipe notes

• Pro tip: Cut vegetables into uniform pieces so they cook evenly and caramelize at the same rate.
• Use baby bella (cremini) mushrooms for a rich, meaty flavor; white button mushrooms or chopped portobello are fine substitutes.
• Swap thyme for other herbs or spices — rosemary, oregano, smoked paprika, or a pinch of chili flakes will all work.
• Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat gently to avoid overcooking.
