How To Buy Broccoli
When selecting broccoli at the grocery store, look for bunches with tightly bound florets and vibrant green color, avoiding any signs of yellowing or florets falling off.
Turn the broccoli over so you can see the underside of the florets; if they look pale yellow, it's a sign that the broccoli is past its prime.
Organic broccoli is readily available at stores like Publix and Whole Foods. To keep it fresh, store broccoli in the refrigerator in a plastic bag for 3 to 5 days.

What You Need
- Fresh broccoli
- Olive oil
- Salt
- Black pepper

How to Roast Broccoli
- Adjust the oven rack to the middle position and heat the oven to 400 degrees Fahrenheit. Line a rimmed baking sheet with parchment paper.
- Wash the broccoli and pat it dry with a paper towel.
- Trim the broccoli florets from the stalk into bite-sized pieces. You can also peel and slice the broccoli stalk into thin rounds, which are also delicious when roasted.
- In a mixing bowl, toss the broccoli florets with olive oil, ensuring they are evenly coated, but not drenched in oil.
- Season the broccoli with salt, pepper, and any other herbs or spices.
- Spread the broccoli pieces in a single layer on the baking sheet, making sure there is room around each piece. This allows them to roast evenly and get crispy.
- Roast the broccoli for about 20 minutes, or until the edges are crisp and golden brown, and the broccoli is tender when pierced with a fork.
- Remove when golden brown. Serve hot.

Best Seasonings for Roasted Broccoli
- Dried spices: Elevate your dish with garlic powder, onion powder, paprika, cayenne pepper, Tajin, lemon pepper, crushed red pepper flakes, or blackened seasoning. Simply mix a spoonful of them into the bowl along with salt and pepper before roasting.
- Cheese: Add a sprinkle of Parmesan cheese, cheddar, or Monterey Jack during the final 5 minutes of roasting for a luscious, melty finish.
- Citrus: Brighten up your cooked broccoli with a squeeze of fresh lemon juice or a sprinkle of lemon zest for a refreshing twist.
- Nuts: Elevate the texture with sliced slivered almonds or crushed macadamia nuts as delicious crunchy toppings.
- Fresh herbs: Scatter parsley, basil, or thyme leaves on your serving plate for a flavor boost and a beautiful garnish.
Top Tips for Perfectly Roasted Broccoli
- Dry Thoroughly: Make sure the broccoli is thoroughly dried after washing so it gets crispy.
- Preheat: Make sure to preheat the oven so the broccoli is evenly roasted.
- Cut florets evenly: Keep the broccoli florets uniform in size so they roast at the same rate. I like to slice the broccoli to about 1 ½ inches wide. All the little pieces that fall off should also be added to the sheet pan. They get very crunchy!
- Use the Stalks: Don't discard the broccoli stalks! Peel off the tough outer layer with a vegetable peeler. Then, slice the broccoli stems into "coins" and roast them alongside the florets. They taste great.
- Use enough oil: Toss the florets in olive oil, avocado oil, or coconut oil to help the broccoli caramelize and prevent burning.
- Seasonings: Salt brings out the flavor in almost everything. I like to use kosher salt or flaky sea salt to season roasted broccoli.
- Face Down: Place the broccoli florets cut-side down on the sheet pan. This allows the large, flat-cut surfaces to caramelize, resulting in uniformly crispy broccoli with golden edges.
- Space it Out: Be careful not to overcrowd the pan and use enough oil that the broccoli caramelizes as it cooks.
- Roast at high heat: Roasting at 400°F is the perfect temperature for roasting broccoli. If you go higher, you may destroy the nutritional value of the vegetable.
Important: Make sure to monitor the oven. Keep an eye on the broccoli as it roasts to prevent burning. Oven temperatures can vary, so check on the broccoli periodically and adjust the cooking time as needed.
To double the recipe, use two sheet pans and rotate the pans in the oven after 10 minutes. You might need another 5 minutes in the oven.
Broccoli Stalk Benefits
The “trunks” of broccoli are rich in sulfur compounds that act as harmful gas to unfriendly bacteria and other microorganisms inside the intestinal tract and also travel straight to the liver, where they saturate liver tissue, allowing the liver’s immune system to have a fighting chance at controlling pathogens.
