Ingredients
- 1 tablespoon oil
- 1 yellow onion, sliced

- 1½ lbs thin-sliced beef (about ⅛-inch thick)
- 8 oz cremini mushrooms, sliced
- 2 tablespoons Worcestershire sauce

- 4 cloves garlic, minced
- ¾ teaspoon salt
- ½ teaspoon black pepper
- 8 oz sliced provolone cheese
Optional Sides:

Instructions
1. Sauté the Onions and Peppers:
- Heat oil in a large oven-safe skillet over medium heat.
- Add onions and cook until softened, about 4–5 minutes.
- Add green peppers and stir-fry another 3–4 minutes, until slightly tender.
- Remove onions and peppers from skillet and set aside.
2. Cook the Beef and Mushrooms:
- If needed, add another splash of oil to the skillet.
- Add the sliced beef and cook until mostly browned.
- Stir in mushrooms and cook until mushrooms are tender and beef is fully cooked through.
3. Build the Casserole:
- Return the onions and peppers to the pan.
- Add Worcestershire sauce, garlic, salt, and pepper.
- Stir in the cream cheese until it melts into the mixture and creates a creamy sauce.
4. Add the Cheese & Broil:
- Top evenly with sliced provolone cheese.
- Place the skillet under the broiler on low heat for 2–3 minutes, or until cheese is fully melted and bubbling.
5. Serve:
- Let it rest for a couple of minutes, then serve hot with your favorite side!
Tips for Success
- Use ribeye or sirloin for the most authentic flavor and tender texture.
- Don’t overcook the beef—remove from heat as soon as it’s no longer pink.
- Swap provolone for mozzarella or Swiss if preferred.
- Want to go low-carb? Skip the sides and enjoy it casserole-style.
