🧾 Ingredients & Their Purpose
Every ingredient in this recipe serves a vital role in creating that iconic Philly flavor and rich texture:
- 1½ lb. Ground Beef – The star of the show, offering juicy, savory protein that forms the hearty base of the casserole.
- 2 Bell Peppers (chopped) – Adds sweetness, color, and that signature cheesesteak veggie crunch.
- ½ Onion (chopped) – Brings savory depth and mild sweetness to balance the richness of the cheese and meat.
- 2 tsp. Minced Garlic – Infuses the dish with aromatic, bold flavor.
- 1 tsp. Seasoned Salt – Enhances all the other ingredients with just the right amount of spice and flavor.
- 8 Slices Provolone Cheese – Smooth, melty, and slightly tangy, provolone is a Philly staple and gives this dish its cheesy soul.
- 4 Large Eggs – Helps bind the ingredients together and forms a creamy, quiche-like layer when baked.
- ¼ cup Heavy Whipping Cream – Adds luxurious richness and keeps the casserole moist and custardy.
- 2 tsp. Worcestershire Sauce – A secret flavor booster that deepens the umami notes and brings complexity to the beef.
👩🍳 Step-by-Step Instructions
1. Preheat & Prep
Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish with nonstick spray or butter to prevent sticking and ensure easy serving.
2. Brown the Ground Beef
In a large skillet over medium-high heat, start browning the ground beef. As it begins to lose its pink color, break it up with a spatula for even cooking.
3. Add Peppers & Onions
Once the beef is partially browned, stir in the chopped bell peppers and onions. Continue to cook until the vegetables begin to soften and the meat is fully browned.
4. Season & Sauté
Add the seasoned salt and minced garlic to the skillet. Sauté for an additional 30 seconds to let the flavors bloom. Drain off any excess grease to prevent a soggy casserole.
5. Assemble the Casserole
Spread the beef and veggie mixture evenly in the bottom of the greased baking dish. Layer the provolone cheese slices across the top, overlapping slightly for full coverage.
6. Make the Egg Mixture
In a bowl, whisk together the eggs, heavy cream, and Worcestershire sauce until well combined. Pour this mixture evenly over the cheese-topped beef in the baking dish.
7. Bake to Perfection
Place the dish in the oven and bake for 35–40 minutes, or until the egg mixture is set, and the top is lightly golden and bubbly.
