Step 6 –Spread the Brussels sprouts onto the other prepared baking sheet.

Step 7 –Roast the squash and the Brussels sprouts until tender and golden, about 20-30 minutes. The squash may need to roast longer than the sprouts.

Step 10 –Add the remaining olive oil to the skillet.

Step 11 –Once the oil is hot, add the flank steak and cook until seared, about 3-4 minutes.

Step 12 –Flip the steak and cook to a minimum of 135 degrees F internally for medium-rare, about 4 minutes, cooking it for longer to reach your desired level of doneness.

Step 13 –Transfer the steak to a plate and slice against the grain into 1-inch-wide strips.

Step 14 –Add the butter and the minced garlic to the cast-iron and cook over medium-low heat until the garlic is softened, about 1-2 minutes.

Step 15 –Add the sliced steak and the thyme to the garlic butter mixture and stir together over medium-low heat until combined, about 1-2 minutes.

Step 16 –Reduce the heat to low and add the butternut squash and the Brussels sprouts to the cast-iron.
