This keto roasted broccoli turns an everyday vegetable into a crave-worthy side with charred, crispy edges, melted Parmesan, and a bright hit of lemon. It is the kind of low-carb dish that disappears off the pan before it reaches the table.
Ingredients
- 1.5 lb fresh broccoli, cut into bite-sized florets
- 3 tablespoons extra-virgin olive oil
- 3 cloves garlic, minced
- 1/3 cup grated Parmesan cheese
- 1/2 teaspoon sea salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon red pepper flakes (optional)
- 1 tablespoon fresh lemon juice
- 2 tablespoons sliced almonds (optional, for crunch)
Instructions
- 1
Preheat the oven to 425°F (220°C) and line a large rimmed baking sheet with parchment paper.
- 2
In a large bowl, toss the broccoli florets with olive oil, minced garlic, salt, pepper, and red pepper flakes until evenly coated.
- 3
Spread the broccoli in a single layer on the baking sheet, cut sides down, leaving space between florets so they roast rather than steam.
- 4
Roast for 18-22 minutes, tossing once halfway through, until the edges are deeply browned and crisp.
- 5
Sprinkle the Parmesan and sliced almonds over the broccoli and return to the oven for 2-3 minutes, until the cheese melts and turns golden.
- 6
Remove from the oven, drizzle with fresh lemon juice, and serve immediately.
Tips & notes
- Dry the broccoli thoroughly after washing — excess moisture steams the florets and prevents the crisp, charred edges that make this dish.
- For extra browning, position the rack in the upper third of the oven and switch to broil for the final 1-2 minutes, watching closely.
- Leftovers keep in an airtight container for up to 3 days; reheat in a hot oven or air fryer to restore crispness rather than the microwave.

Frequently asked questions
- How many carbs are in keto roasted broccoli?
- Each serving has 3.4g net carbs, 178 calories, 6g protein, and 15g fat. This recipe makes 4 servings, making it an easy fit for a keto or low-carb side dish.
- Can I make keto roasted broccoli dairy-free?
- Yes. Skip the Parmesan or swap in 2 tablespoons of nutritional yeast for a cheesy, savory flavor. This drops the dish to about 3g net carbs and keeps it fully dairy-free and vegan.
- Can I use frozen broccoli instead of fresh?
- You can, but thaw it first and pat it very dry, since frozen broccoli releases extra water. Roast it at 425°F for 25-30 minutes for the best browning, as it will take longer to crisp than fresh florets.
