Tips for Success
Here are some of my favorite tips to help you nail this recipe:
- Make sure to slice the vegetables evenly for even cooking.
- Don’t overcrowd the baking sheet; give the veggies room to roast properly.
- If you want to prep ahead, you can slice the veggies a day in advance and store them in an airtight container in the fridge.
How to Store Oven Roasted Zucchini and Squash
To store any leftovers, let them cool completely and then place them in an airtight container. They will keep in the refrigerator for up to 3 days. You can reheat them in the oven or microwave. Just be aware that reheating may soften them further, so they are best enjoyed fresh!
