In large skillet, heat oil and butter over medium-high heat; add garlic and sauté 1 minute.
Add broccoli spears, salt and pepper. Sauté broccoli until garlic is golden brown and broccoli is cooked (about 3-4 minutes). Remove from heat and place in an ovenproof shallow serving dish. (Broccoli can be covered and refrigerated several hours or overnight).
Sprinkle broccoli with Parmesan cheese; place under broiler (HIGH) and broil until cheese is melted and golden brown (about 5-7 minutes).
