Easy Oven Beef Strips Recipe

Rest Time
5 minutes
Servings

Ingredients
- 1½ pounds beef strips or thinly sliced steak
- 1 can (10.5 ounces) condensed cream of mushroom soup
- 1 packet dry onion soup mix
- ½ cup water
- 2 tablespoons soy sauce
Instructions
1. Preheat the Oven
Heat your oven to 350°F (175°C).
Lightly grease or prepare a 9×13-inch baking dish.
2. Arrange the Beef
Spread the raw beef strips evenly across the bottom of the baking dish.
Try to keep the pieces mostly in a single layer for even cooking.
3. Prepare the Sauce
In a medium bowl, combine:
- Cream of mushroom soup
- Dry onion soup mix
- Water
- Soy sauce
Stir until smooth and fully blended.
4. Cover the Beef
Pour the sauce mixture evenly over the beef strips.
Use a spoon to spread the sauce around so most of the meat is coated.
5. Bake
Cover the dish tightly with aluminum foil.
Bake for 1 hour.
6. Check for Tenderness
Carefully remove the foil and stir gently.
If the beef still feels firm, cover again and continue baking for another 15–20 minutes until tender and the sauce becomes hot and bubbly.
7. Rest and Serve
Allow the dish to rest for about 5 minutes before serving.
Serve warm over:
- Rice
- Egg noodles
- Mashed potatoes
- Cauliflower rice
Helpful Tips
Choose Tender Cuts
Thinly sliced sirloin, flank steak, or packaged stir-fry beef work especially well.
Cut Against the Grain
Slicing beef against the grain helps create a softer, more tender texture.
Keep the Dish Covered
The foil traps steam and helps the beef cook gently without drying out.
Taste Before Adding Salt
Both the onion soup mix and soy sauce already contain salt, so extra seasoning may not be necessary.
Make the Sauce Thicker
For a thicker gravy, stir in a cornstarch slurry after baking and return the dish to the oven uncovered for a few extra minutes.
