Not sure if these overlap with your current go-to's, but here's a couple of ways I season my roasted potatoes. Assume all are drizzled heavily in olive oil:

• Cajun seasoning (unsure of specific ingredients, but sold in a shaker as just "Cajun seasoning")
• Black, red, and green peppers, salt, garlic, onion, parsley, paprika (often sold premixed in a grinder as "Steakhouse seasoning")
• Rosemary, black/red pepper, garlic, onion, dried tomato flakes, parsley (often sold premixed in a grinder as "Italian herb")
• Salt, pepper, and basil

Fair warning: I'll eat literal cardboard if you put enough olive oil and basil on it.
