These savory grilled steak fajita foil packs are an easy, flavorful dinner perfect for busy nights. The foil packs lock in juices and caramelize veggies for tender, smoky fajitas with minimal cleanup.
Slice steak thinly against the grain for tenderness. Marinate for at least 30 minutes for best flavor. Seal foil packs tightly to lock in steam and juices. Use a spray bottle to manage grill flare-ups. For extra char, open packs and grill contents directly for 1-2 minutes per side before serving. Can be cooked in oven at 400°F for 20-25 minutes if no grill is available. Foil packs can be assembled ahead and refrigerated up to 24 hours or frozen uncooked for up to 2 months.
