- Seal It Tight… Use an airtight container to lock in freshness. Stored properly, these veggies will stay good in the fridge for up to 3 days.

Tips & FAQs
How do I roast broccoli and cauliflower in the oven?
Start by preheating your oven to 425°F (220°C). Wash and dry the vegetables, then cut them into uniform florets. Toss them in olive oil, salt, and pepper, and spread them on a baking sheet. Roast for 20-25 minutes, flipping halfway through, until they are golden brown and tender.
How long should I roast broccoli and cauliflower?
At 425°F, roast for 20-25 minutes. If you’re using a lower temperature, like 350°F, you’ll need about 25-30 minutes. Always flip halfway for even roasting and keep an eye on them near the end to avoid overcooking.
Can I roast broccoli and cauliflower together?
Absolutely! Since they have similar roasting times, they’re perfect to cook together. Just make sure to spread them out in a single layer on the baking sheet to ensure even roasting.
What’s the best temperature to roast broccoli and cauliflower?
For the crispiest, most flavorful results, roast at 425°F. This high heat caramelizes the natural sugars in the vegetables, giving them that perfect golden-brown edge.
How can I prevent broccoli and cauliflower from getting soggy?
Pat the vegetables dry after washing, toss them lightly in oil, and avoid overcrowding the baking sheet. Spread them out in a single layer to allow proper air circulation during roasting.
Can I add other vegetables to the mix?
Yes! Carrots, bell peppers, or zucchini pair well with broccoli and cauliflower. Just cut them to similar sizes and adjust the roasting time as needed for each vegetable.
Is it okay to use frozen broccoli and cauliflower?
Yes, you can use frozen vegetables, but they should be thawed and patted dry before roasting. This helps prevent steaming and ensures crispier results.
How can I enhance the flavor of roasted broccoli and cauliflower?
Add garlic, smoked paprika, red pepper flakes, or a sprinkle of Parmesan cheese. For a burst of freshness, drizzle lemon juice or zest over the roasted veggies before serving.
How do I store and reheat roasted broccoli and cauliflower?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 375°F or use an air fryer to regain the crispy texture. Avoid microwaving, as it can make the veggies soggy.
