Why You Will Love This Recipe
For home cooks, the best meals are those that do not require a lot of prep but provide a good dose of satisfaction. This recipe has only four ingredients and very little hands-on time. Just put the foil packets together, and let the oven do the rest.
The foil helps seal in the moisture and flavor as it cooks. While the beef roasts, the juices from the beef mix with the onions and seasonings to create a flavorful, savory sauce right in the packet.
Cleanup is another positive. All the cooking is done in foil, so you spend less time washing dishes and more time enjoying dinner. That convenience can be a huge difference on busy weeknights for families.
The Four Elements
One of the reasons this recipe has stayed so popular is simplicity.
You will need:
-
4 cube steaks or sirloin steaks of beef
-
2 large onions, sliced
-
1 packet dry onion soup mix
-
4 tablespoons of butter
That is all. These ingredients are super flavorful for no extra effort. As the onions cook, they soften and take on their natural sweetness. The butter adds richness, and the onion soup mix adds savory seasoning that goes great with beef. It is a meal that together tastes like it took a lot more work than it actually did.
Oven-Baked Beef Steak and Onion Foil Bake Recipe
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Tear off four large sheets of heavy-duty aluminum foil.
Step 2: Assemble the Packets
Place one steak in the center of each foil sheet. Spread the sliced onions evenly over the steaks. Sprinkle the onion soup mix evenly over each serving. Add one tablespoon of butter to each packet.
Step 3: Seal and Bake
Wrap the foil tightly around the ingredients, making sure the edges are sealed well. Place the packets on a baking sheet. Bake for 40 to 45 minutes.
Step 4: Serve
Carefully open the packets, as hot steam will escape immediately. Slide the steaks onto plates and spoon the onions and cooking juices over the top.
