Step 1

Preheat the oven to 450 degrees F, or to 475 degrees F for crispier broccoli.

In a large mixing bowl, whisk together the olive oil, lemon zest, lemon juice, salt, pepper, red pepper flakes, ranch seasoning, and garlic.

Step 3

Add the broccoli and toss to coat.

Step 4

Spread the broccoli onto a large rimmed baking sheet.

Step 5

Roast for 10-12 minutes.

Step 6

Flip the broccoli and add the almond slices to the sheet.

Step 7

Roast until the broccoli reaches desired tenderness, about 5-10 minutes. Keep a close eye on the almonds, as they can burn quickly.
