How to Make Delicious and Easy Philly Cheesesteak Casserole Recipe
Step 1: Prepare the Marinade
Combine red wine vinegar, Worcestershire sauce, baking soda, half of the minced garlic, onion powder, thyme, salt, pepper, and water in a large bowl. Whisk until well combined.
Step 2: Slice and Marinate Steak
Thinly slice the flank steak against the grain using a sharp knife, making sure the slices are no thicker than 1/8 inch. Add the sliced steak to the marinade and let it marinate for 15-30 minutes to tenderize the meat.
Step 3: Prep Vegetables and Oven
While the steak is marinating, slice the bell peppers and onion. Grate the jack cheese and allow the cream cheese to soften at room temperature. Preheat the oven to 400°F.
Step 4: Cook the Steak
In a large skillet over medium heat, heat 1 tablespoon butter and oil. Drain marinade from steak, discard liquid, and cook steak in batches until browned on all sides. Do not be concerned about foaming from baking soda. Remove cooked steak and set aside.
Step 5: Sauté Vegetables
Add the rest of the butter to the skillet. Sauté bell peppers and onions until softened, approximately 5 minutes. Stir in the remaining minced garlic and cook for another minute until fragrant.
Step 6: Make Cheese Sauce
Add cubed cream cheese and heavy cream to the vegetables. Stir until cream cheese is completely melted. Bring to a gentle simmer, then stir in shredded jack cheese until smooth. Remove from heat.
Step 7: Assemble and Bake
Add the cooked steak back to the skillet with the cheese sauce, combine well. Transfer the mixture to a greased casserole dish, top with provolone slices. Bake for 15 minutes until the cheese is melted and golden brown. Garnish with chopped parsley before serving.
Storage Tips
After preparing the Philly cheesesteak casserole, you can store any leftovers in the refrigerator for up to three days. Make sure to transfer the casserole to an airtight container or cover it tightly with plastic wrap before refrigerating. When ready to enjoy again, simply reheat individual portions in the microwave for a quick and convenient meal.
If you want to prepare the casserole in advance, you can assemble the dish, cover it tightly, and refrigerate for up to two days before baking. When you’re ready to serve, remove the plastic covering, cover with foil, and bake for 40-50 minutes until heated through. Towards the end of baking, uncover the casserole to allow the cheese to brown. This make-ahead option is perfect for meal prep situations or when you want to have dinner ready to go with minimal effort. Additionally, the Philly cheesesteak casserole can be frozen for up to a month for longer-term storage.
Ingredient Substitutions
For a vegetarian version of this Philly cheesesteak casserole, you can substitute the flank steak with meat alternatives like seitan or soy curls that have a chewy texture and can absorb the marinade flavors well. Additionally, you can replace the Worcestershire sauce with a vegan-friendly Worcestershire sauce or soy sauce for a similar umami kick. Consider using vegetable broth instead of water for added depth of flavor in the dish.
If you’re looking to lower the dairy content, you can swap the cream cheese with a plant-based cream cheese alternative and use a vegan cheese blend in place of the Monterey Jack and provolone cheeses. Cashew cream or coconut milk can be used instead of heavy cream for a creamy texture. You can also experiment with different vegan cheese options like mozzarella or cheddar alternatives that melt well and add a cheesy goodness to the casserole.
Serving Suggestions
Serve your Philly cheesesteak casserole hot from the oven with a sprinkling of fresh chopped parsley on top for a pop of color and freshness. Pair it with a simple green salad or roasted vegetables to balance out the richness of the dish. Don’t forget to have some crusty bread or dinner rolls on hand for soaking up any extra sauce – it’s a delicious way to enjoy every last bit of flavor!
For a fun twist, try turning this Philly cheesesteak casserole into a party dip. Simply transfer the cooked casserole into a baking dish, top it with extra shredded cheese, and bake until bubbly.
