Why You’ll Love This Philly Cheesesteak Casserole

This recipe is ideal for:

• Busy weeknights when you need a fast, filling dinner

• Meal preppers who want a make-ahead dish that stores well

• Low-carb or keto eaters seeking comforting food without the carbs

• Cheesesteak fans looking for a fun twist on the classic

Unlike a traditional cheesesteak, this casserole ditches the bread and embraces the magic of a creamy egg base to bind all the classic ingredients together—think sautéed beef, bell peppers, onions, melted provolone, and a luscious layer of cream cheese. It’s a whole new way to love Philly cheesesteak, and it’s as easy as it is satisfying.

Ingredients Breakdown

Let’s take a closer look at what makes this casserole a standout:

• 1 lb ground beef or shaved steak – Choose based on your preference. Ground beef is budget-friendly and widely available, but shaved ribeye gives a more authentic Philly cheesesteak flavor.

• 1 green bell pepper, chopped – Adds color, crunch, and freshness.

• 1 onion, chopped – A must for that classic cheesesteak aroma and taste.

• 8 oz cream cheese, softened – Creates a creamy, indulgent base.

• ½ tsp garlic powder – Subtle seasoning to enhance the savoriness.

• Salt and pepper, to taste – Always essential!

• 1 cup shredded provolone or mozzarella cheese – Provolone keeps it traditional, while mozzarella adds meltiness.

• 4 large eggs – Helps bind the casserole and adds protein.

• ¼ cup heavy cream – Richness and creaminess to pull it all together.

Step-by-Step Directions

1. Preheat and Prep
Set your oven to 350°F (175°C). Lightly grease a baking dish and set it aside.

2. Sauté the Savories
In a large skillet over medium heat, cook the beef (or shaved steak), bell pepper, and onion until the meat is browned and the vegetables are tender. Drain off any excess grease.

3. Make It Creamy
Stir in the softened cream cheese, garlic powder, salt, and pepper. Mix until everything is smooth and evenly combined.

4. Add the Egg Mixture
In a separate bowl, whisk together the eggs and heavy cream. Pour this mixture into the skillet and stir everything together to coat the meat and veggies evenly.

5. Assemble and Bake
Transfer everything to your prepared baking dish. Top with shredded cheese and bake for 25–30 minutes, or until the casserole is set, golden, and bubbly.
