How to Make Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Grease a 9×9 baking dish with cooking spray or butter to prevent sticking.
Step 2: Brown the Ground Beef
Place a large skillet over medium-high heat.
Add the ground beef and cook until it begins to brown, breaking it apart with a spatula as it cooks.
Step 3: Add the Vegetables
Once the beef is partially browned, add the chopped onions and bell peppers.
Continue cooking until:
- The beef is fully cooked
- The onions become translucent
- The peppers soften slightly
This step builds incredible flavor and gives the casserole its classic cheesesteak taste.
Step 4: Add Garlic and Seasoning
Stir in:
- Minced garlic
- Seasoned salt
Cook for another 30 seconds until fragrant.
Drain any excess grease from the skillet to keep the casserole from becoming oily.
Step 5: Assemble the Casserole
Transfer the beef and vegetable mixture into the prepared baking dish.
Spread it evenly across the bottom.
Lay the provolone cheese slices over the beef mixture, covering as much surface area as possible.
Step 6: Prepare the Egg Mixture
In a mixing bowl, whisk together:
- Eggs
- Heavy whipping cream
- Worcestershire sauce
Mix until fully combined.
Carefully pour the mixture over the meat and cheese layers.
Step 7: Bake
Place the casserole into the preheated oven.
Bake for 35 to 40 minutes, or until:
- The eggs are fully set
- The top is lightly golden
- The casserole is cooked through
Allow it to rest for about 5 minutes before serving.
Tips for the Best Philly Cheesesteak Casserole
Don’t Overcook the Vegetables
The peppers and onions should soften slightly but still retain a little texture.
Use Freshly Shredded Cheese
If using shredded cheese instead of slices, freshly shredded cheese melts better than pre-packaged varieties.
Let It Rest Before Slicing
Giving the casserole a few minutes to rest helps everything set properly.
Add Mushrooms
For an authentic steakhouse flavor, sauté sliced mushrooms with the peppers and onions.
Spice It Up
Add red pepper flakes or diced jalapeños if you like a little heat.
