Ingredients

10 oz frozen broccoli florets
Olive oil spray

Salt
Pepper

Garlic powder
Onion powder

Instructions

Step 1: Preheat the oven to 420 degrees Fahrenheit.
Step 2: Line a baking sheet with parchment paper for easy cleanup.
Step 3: Place the frozen broccoli florets directly from the freezer onto the baking sheet in an even layer.

Step 4: Spray the broccoli lightly with olive oil spray to coat evenly.
Step 5: Sprinkle salt, pepper, garlic powder, and onion powder evenly over the broccoli. There’s no need to toss or stir at this point.
Step 6: Roast in the oven for 15 to 20 minutes, checking once or twice to gently stir the broccoli. Roast until the florets are crisped to your liking.

Step 7: Remove from the oven and, if desired, sprinkle with parmesan cheese or nutritional yeast for a dairy-free option.
Step 8: Serve immediately while hot and enjoy.

Tips & Variations

For extra crispiness, spread the broccoli out so it isn’t crowded on the baking sheet.

Try adding a squeeze of fresh lemon juice after roasting for bright flavor.
Swap out garlic powder for smoked paprika to add a smoky twist.
If you prefer, toss the broccoli with the seasonings before roasting for more even coating.

Storage

Store any leftover roasted broccoli in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or a toaster oven at 350 degrees Fahrenheit for 5-7 minutes to regain crispiness. Avoid microwaving to keep it from becoming soggy.

How to Serve

The image shows small roasted broccoli florets scattered over a layer of light brown parchment paper on a white marbled surface. The broccoli pieces vary in size, with a bright green color and slightly charred edges that give a crispy texture. A fine, crumbly sprinkle of white cheese or seasoning is spread evenly over the broccoli and parchment paper. The parchment paper has small oil and charred spots from roasting. A small part of a red silicone glove is visible at the edge of the frame, and a white marbled texture serves as the background space. photo taken with an iphone --ar 4:5 --v 7
