How do I store leftover Sautéed Zucchini and Mushrooms with Garlic and Thyme?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep sliced cremini mushrooms from drying out.

Can I substitute ingredients in Sautéed Zucchini and Mushrooms with Garlic and Thyme?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Sautéed Zucchini and Mushrooms with Garlic and Thyme for a different number of people?
