Layer Onions and Two Simple Ingredients with Steak for a Baked Dinner That Never Gets Old
Some nights, you don’t want complicated.
You want something hearty. Reliable. Comforting.
A meal that feels like you put in effort—even if you didn’t.
With just steak, onions, oil or butter, and basic seasoning, everything cooks together inside a sealed foil packet. The steam keeps the meat tender, while the onions soften and turn slightly sweet. The result is flavorful, satisfying, and surprisingly low-maintenance.
It’s the kind of meal that works just as well on a busy Tuesday as it does for a casual family dinner.
And the cleanup? Minimal.
Why This Recipe Works So Well
Foil-packet cooking is simple, but there’s real logic behind it.
When sealed properly:
- Moisture stays trapped
- Steam circulates around the steak
- Onions release natural juices
- Fat from oil or butter coats the meat
- Seasonings distribute evenly
Instead of drying out in the oven, the steak cooks gently in its own flavorful environment.
That’s what keeps it tender.
Choosing the Right Cut of Steak
This recipe works best with:
- Sirloin
- Round steak
- Chuck steak
If you’re using a tougher cut, slicing it into portions helps it cook more evenly.
Patting the steak dry before seasoning also helps the surface cook more consistently.
4-Ingredient Oven-Baked Steak and Onion Foil Bake
Servings: 4
Ingredients
- 1½ to 2 pounds beef steak (sirloin, round, or chuck)
- 2 large onions, thinly sliced
- 3 tablespoons olive oil or melted butter
- 1½ teaspoons salt + 1 teaspoon black pepper
Directions
- Preheat oven to 400°F (200°C).
- Tear 4 large sheets of heavy-duty foil.
- Toss sliced onions with oil or melted butter and half the seasoning.
- Season steak portions on both sides with remaining salt and pepper.
- Divide onions into four piles on foil sheets.
- Place steak on top of each onion bed.
- Fold foil tightly to seal completely.
- Bake 20–25 minutes for medium doneness.
- Let rest 5 minutes before carefully opening.
Always open packets slowly—steam will be hot.
Spoon the soft onions and juices over the steak before serving.
What to Serve with It
This meal pairs well with:
- Baked or mashed potatoes

The natural juices inside the foil are perfect for soaking into starches.

That flexibility makes this a practical go-to meal.
