This 5-ingredient beef and onion foil packet dinner is the ultimate weeknight lifesaver. It’s got that classic Midwest comfort-food vibe—hearty, savory, and satisfying—but with minimal prep and almost zero cleanup. Foil packets have long been a camping and cookout favorite, and this oven version brings the same magic indoors. Perfect for busy weekdays, these packets deliver a flavorful, cozy dinner straight from the oven to your plate.
For a balanced meal, serve with a crisp green salad, steamed green beans, or roasted broccoli. Crusty bread or dinner rolls are perfect for soaking up the juices, and leftovers make fantastic tortilla wraps with a little cheese and salsa.

Ingredients
-
1½ pounds thinly sliced beef steak (sirloin or round work well)

Salt and black pepper, to taste (optional)

Nonstick cooking spray for foil (optional)
Directions
-
Prep the oven and foil: Preheat to 400°F (200°C). Line a baking sheet with foil for easy cleanup. Tear four 12x18-inch sheets of heavy-duty foil and lightly spray the centers with nonstick cooking spray if desired.

Prep the ingredients: Slice onions and halve potatoes. Pat beef dry and slice into strips if needed.
-
Season the veggies: In a large bowl, toss the potatoes and onions with olive oil, steak seasoning, and a pinch of salt and pepper. This ensures even seasoning throughout.
