Step-by-Step Instructions
Step 1: Prepare the Beef
Preheat your oven to 350°F (175°C). Place a large sheet of aluminum foil on a baking tray and set the beef in the center. Pat the meat dry and season generously with salt and black pepper on all sides.
Step 2: Add the Onions
Pile the sliced onions directly on top of the beef. Don’t worry if it looks like a lot—onions shrink as they cook and will become soft and sweet, soaking up all the juices.
Step 3: Top with Butter and Garlic
Scatter small cubes of butter over the onions. Sprinkle minced garlic or garlic seasoning evenly across the top. If you like extra flavor, add a pinch of Italian seasoning or steak seasoning at this stage.
Step 4: Seal It in Foil
Bring the edges of the foil up and fold them tightly to create a sealed packet. This step is crucial—it keeps steam inside so the beef stays tender while baking.
Step 5: Bake Until Tender
Place the foil-wrapped beef into the oven and bake for 1½ to 2 hours, depending on the thickness of the cut. The longer it cooks, the more tender it becomes.
Step 6: Rest and Serve
Carefully open the foil (watch for hot steam) and let the beef rest for a few minutes. Spoon the buttery onion mixture over the meat before serving.
Serving Ideas
This baked beef pairs perfectly with mashed potatoes, roasted vegetables, or crusty bread to soak up the juices. You can also slice or shred the meat and serve it over rice or noodles.
