How to Make Roasted Broccoli and Cauliflower
Step 1: Prep Your Oven and Pan
Preheat your oven to 400°F (204°C). Line a large baking sheet with foil for easy cleanup.
Step 2: Season the Vegetables
In a large bowl, combine the broccoli and cauliflower florets. Drizzle with olive oil, add minced garlic, and sprinkle with half the Parmesan cheese. Toss everything together, making sure each piece is well-coated.
Step 3: Arrange and Roast
Spread the vegetables in a single layer on your prepared baking sheet. Don’t overcrowd them – this is key for achieving that perfect crispy texture. Roast for 25-30 minutes, giving them a gentle toss halfway through.
Step 4: Add the Finishing Touches
Once roasted to golden perfection, sprinkle the remaining Parmesan cheese over the hot vegetables. Give them a final toss and adjust the seasoning if needed.
Pro Tips for Making the Recipe
- Even Sizing: Cut your florets into similar sizes to ensure even cooking.
- Dry Vegetables: Make sure your veggies are completely dry before roasting to achieve maximum crispiness.
- Don’t Overcrowd: Give your vegetables plenty of space on the baking sheet. If needed, use two sheets.
- High Heat is Key: Don’t be tempted to lower the oven temperature. High heat is crucial for those crispy edges.
How to Serve

This versatile dish pairs beautifully with so many mains:
- Serve alongside grilled chicken or fish for a light and healthy meal.
- Toss with pasta and a drizzle of olive oil for a quick vegetarian dinner.
- Use as a topping for grain bowls or salads for added crunch and flavor.
Make Ahead and Storage
Storing Leftovers

Freezing
While best enjoyed fresh, you can freeze roasted broccoli and cauliflower. Spread them on a baking sheet, freeze until solid, then transfer to a freezer bag. They’ll keep for up to 3 months.
Reheating
For best results, reheat in a 350°F oven or air fryer until warmed through and crispy again. Avoid the microwave if you want to maintain the crispy texture.

Description
Roasted Broccoli and Cauliflower is a delicious and healthy side dish that combines the earthy flavors of broccoli and cauliflower with the savory notes of garlic and Parmesan cheese. This simple recipe transforms these vegetables into a crispy, golden-brown delight that’s perfect for any meal.
Ingredients
- 4 cups Broccoli (cut into florets; fresh or frozen)
- 4 cups Cauliflower (cut into florets; fresh or frozen)
- 1/3 cup Olive oil
- 6 cloves Garlic (minced)
- 2/3 cup Grated parmesan cheese (divided)
- Sea salt (to taste)
- Black pepper (to taste)
Instructions
- Preheat and Prepare: Preheat the oven to 400 degrees F (204 degrees C). Line a large baking sheet (or two smaller ones that can fit side by side) with foil, or use a quality non-stick baking sheet and skip lining it.
- Mix Ingredients: In a large bowl, combine the broccoli and cauliflower florets. Add the olive oil, minced garlic, and half of the parmesan cheese. Toss everything together until the vegetables are evenly coated. Season with sea salt and black pepper to taste, then toss again to distribute the seasonings.
- Arrange and Roast: Spread the seasoned vegetables in a single layer on the prepared baking sheet(s), ensuring they have plenty of space between them. Roast in the preheated oven for 25-30 minutes if using fresh florets, or 30-35 minutes for frozen ones. Halfway through the cooking time, toss the vegetables to ensure even browning.
- Finish and Serve: Just before serving, remove the roasted vegetables from the oven and toss them with the remaining parmesan cheese. Taste and adjust the seasoning with additional salt and pepper if needed.
Notes
- For evenly cooked florets with crispy edges, ensure vegetables are spread in a single layer and not overcrowded on the baking sheet.
- Experiment with different seasonings like Italian herbs, lemon zest, or red pepper flakes for variety.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.
- To freeze, flash freeze the roasted vegetables on a sheet pan, then transfer to a freezer bag and store for up to 3 months.
- For reheating, use an air fryer or a 350°F oven for best results. Microwaving is quick but may result in softer vegetables.
