Pro Tips
• Roast from Frozen: Do not thaw the broccoli first! Roasting directly from frozen is the key to avoiding a soggy texture and achieving maximum crispiness.
• Don’t Crowd the Pan: Spread the florets in a single, even layer with space between them. Overcrowding the pan will cause the broccoli to steam instead of roast.
• Use a Hot Pan: For an extra-crispy sear, place your empty baking sheet in the oven as it preheats. Carefully add the seasoned broccoli to the hot pan to jumpstart the caramelization.

No — roast it straight from the freezer. Thawing is the fastest route to soggy broccoli; the frozen florets roast up crisp when they hit the hot pan.

Most likely the florets were thawed first or the pan was overcrowded. Keep them frozen and spread them in a single layer with space between them.

Each of the 4 servings has about 1.8 g of net carbs (5.6 g total, 3.8 g fiber) with 3.2 g of protein and 3.8 g of fat. The only ingredients are broccoli, olive oil, and sea salt.
How do I store leftovers?
Refrigerate the roasted florets for 3-4 days and re-crisp them on a hot sheet pan or in the air fryer for a few minutes before serving.
