Ingredients

For the roasted broccoli

1 1/2 pounds fresh broccoli crowns, cut into medium florets
3 tablespoons extra-virgin olive oil
1 teaspoon fine sea salt or to taste
1/2 teaspoon freshly ground black pepper or to taste

For the roasted garlic

1 head garlic top trimmed to expose cloves
1 teaspoon olive oil for drizzling garlic

Optional keto toppings

1/4 cup freshly grated Parmesan cheese for sprinkling after roasting
1/4 teaspoon crushed red pepper flakes for heat, optional
1 teaspoon lemon zest optional, added after roasting

Instructions

Preheat the oven to 425°F and line a large baking sheet with parchment paper for easy cleanup.
Prepare the garlic by slicing about 1/4 inch off the top of the head to expose the cloves, placing it on a small piece of foil, drizzling with the teaspoon of olive oil, and wrapping it tightly in the foil.
Add the foil-wrapped garlic packet to one corner of the prepared baking sheet.
Place the broccoli florets in a large mixing bowl and drizzle with the extra-virgin olive oil, then sprinkle with the salt and black pepper.
Toss the broccoli well until all florets are evenly coated with the oil and seasonings, making sure the flat cut sides are lightly oiled to encourage caramelization.
Spread the seasoned broccoli in a single layer on the baking sheet, leaving space between florets so they roast instead of steam.
Roast the broccoli and garlic for 20 to 25 minutes, flipping the broccoli once halfway through, until the broccoli edges are browned and crisp and the stems are just tender.
Remove the baking sheet from the oven and carefully unwrap the garlic, letting it cool just enough to handle.
Squeeze the softened roasted garlic cloves out of the skins into a small bowl and mash them with a fork into a smooth paste.
Transfer the hot roasted broccoli back to the mixing bowl, add the roasted garlic paste, and toss until the garlic is distributed evenly over the florets.
Sprinkle the broccoli with Parmesan, red pepper flakes, and lemon zest if using, tossing gently to combine.
Taste and adjust the seasoning with additional salt and pepper if needed, then serve the roasted garlic broccoli hot as a keto side, snack, or part of a meal prep bowl.

Notes

For the best texture, keep the broccoli florets similar in size so they roast evenly and avoid crowding the pan, which can cause steaming instead of browning. If you prefer a stronger garlic flavor, roast a second head of garlic and add more of the paste to taste, keeping in mind that the mellow sweetness can mask how intense the flavor becomes. This dish reheats well in an oven or air fryer to restore crisp edges, while microwaving is convenient but will soften the florets. Serve alongside roasted chicken, steak, pork chops, or salmon, or mix into a keto bowl with eggs, avocado, and cheese for a complete low carb meal.
