• Bacon (3 slices) – Bacon adds a rich, smoky flavor and crispy texture that perfectly complements the roasted vegetables.
• Garlic (¼ cup) – Fresh garlic infuses the dish with a bold, savory depth that enhances every bite.
• Broccoli (1 crown) – Broccoli becomes tender and slightly caramelized when roasted, adding hearty texture and earthy flavor.
• Cauliflower (1 crown) – Cauliflower roasts beautifully, developing a nutty sweetness that pairs well with the seasonings and cheese.
• Lemon juice (2 tbsp) – Lemon juice brightens the dish with a fresh, tangy flavor that balances the richness of the bacon and parmesan.
• Olive oil (2 tbsp) – Olive oil helps the vegetables roast evenly while adding a subtle richness and promoting golden-brown caramelization.
• Celtic sea salt (1 tsp) – Celtic sea salt enhances the natural flavors of the vegetables and brings all the ingredients together.
• Italian herb blend (1 tbsp) – An Italian herb blend adds aromatic notes of herbs like oregano, basil, and thyme for classic Mediterranean flavor.
• Pepper (1 tsp) – Freshly ground pepper provides a mild heat and savory spice that complements the roasted vegetables.
• Grated parmesan cheese (¼ cup) – Parmesan cheese adds a salty, nutty finish that melts into the vegetables and creates irresistible flavor.

Steps to Make Roasted Parmesan Broccoli Cauliflower

Once you have assembled the ingredients, use this method.

Cook Bacon. In large, heavy pan, lightly brown diced strips of bacon. Remove bacon from pan when lightly browned, set aside. Remove much of the bacon grease from the pan (a little is perfect – but you don’t want too much- just enough to glisten across the bottom of the pan, but not enough to pool up.)

Florets. Add broccoli, cauliflower, and garlic to pan. Drizzle with lemon juice, olive oil, salt and pepper, and herbs – toss well to coat evenly.

Bake. Preheat oven to 425 degrees. Place in oven and roast for 30 minutes – until vegetables have started to brown and have reduced in size by about a third.

Add Cheese. Add bacon to pan, and sprinkle vegetables with parmesan. Roast for another 5-10 minutes, until parmesan is golden and vegetables have browned bits and are tender to the touch – but aren’t too soft. For softer vegetables, add 10 minutes oven time before adding bacon and parmesan. Remove from oven and serve immediately.

Tips to and Tricks Perfect Parmesan Oven Roasted Broccoli and Cauliflower

Bake Broccoli Quickly at High Heat. Since broccoli has a unique, looser structure compared with cauliflower (and the water content is a bit different), it holds up a lot better to heat and doesn’t get mushy right away – but if you love broccoli with a bit of bite (instead of a mushy lump), it’s best to cook it quickly at high heat.

Don’t overcook the broccoli or cook it too slowly. I am sure you’ve tried a broccoli dish from a slow cooker that didn’t have a ton of texture – the crunchy texture is fabulous for roasted broccoli in the oven – and gives the broccoli a deep, rich buttery flavor you won’t get without the oven’s high heat.

Let it Brown. Slightly browned broccoli crowns fresh from roasting in the oven are PACKED with flavor – let the broccoli brown and crisp, even if it’s only on one side.

Stir the dish less. don’t worry too much about flipping the broccoli over, as it’s more important to us in this recipe to develop a deep caramelization from the vegetables for the best flavor.

Bacon Parmesan Roasted Broccoli and Cauliflower FAQs

Yes, you can prep the vegetables and seasonings up to a day in advance. Store everything separately in the refrigerator and roast just before serving for the best texture and flavor.

Make sure the vegetables are thoroughly dried after washing and spread them in a single layer on the baking sheet. Overcrowding the pan can cause the vegetables to steam instead of roast.

Yes, but fresh vegetables provide the best texture. If using frozen vegetables, thaw and drain them well before roasting to remove excess moisture.

Pecorino Romano, Asiago, or a dairy-free parmesan alternative can be used as a substitute while still providing a savory, cheesy flavor.
