Oven-Baked Beef & Onion Foil Packet is a simple, flavorful, and low-cleanup meal where tender beef and sweet onions are cooked together in foil, locking in juices and seasonings. It’s perfect for a quick weeknight dinner or meal prep.
🥩 Key Features
- Protein: Beef (steak strips, ground beef, or thinly sliced roast).
- Vegetables: Onions are classic; you can also add bell peppers, carrots, or potatoes.
- Cooking method: Sealed in foil packets and baked in the oven, which steams the ingredients in their own juices.
- Flavor: Seasoned with garlic, herbs, salt, pepper, and optional sauces (soy sauce, Worcestershire, or BBQ).
🥄 Basic Ingredients
- 1 lb (450 g) beef, thinly sliced or cubed
- 1–2 medium onions, sliced
- 2–3 cloves garlic, minced
- 1–2 tbsp olive oil or butter
- Salt and pepper to taste
- Optional: herbs like thyme or rosemary, soy sauce, or Worcestershire sauce
🔥 Step-by-Step Instructions
- Preheat oven to 200°C (400°F).
- Prepare foil packets: Tear large squares of heavy-duty aluminum foil.
- Assemble ingredients: Place beef, onions, garlic, and any optional vegetables on the foil. Drizzle with oil and seasonings.
- Seal the packets: Fold the foil over and crimp edges tightly to prevent steam from escaping.
- Bake: 20–30 minutes for thinly sliced beef; 30–40 minutes for cubed roast or thicker cuts.
- Serve: Carefully open the packets (steam is hot!) and enjoy with rice, mashed potatoes, or a side salad.
🍴 Tips
- Uniform slicing: Makes sure everything cooks evenly.
- Extra flavor: Add a splash of beef broth or balsamic vinegar before sealing.
- One-pan cleanup: The foil catches all juices—minimal washing required.
