Ingredients You’ll Need

Here’s a breakdown of everything you’ll need to make Philly Cheesesteak Casserole from scratch:

680g ground beef – Rich, juicy, and packed with protein
2 bell peppers, chopped – Use different colors (like red and green) for flavor and visual appeal
½ large onion, chopped – Adds sweetness and savory depth
2 teaspoons minced garlic – Boosts aroma and flavor
1 teaspoon seasoned salt – Enhances all the savory components
8 slices provolone cheese – Melty, creamy, and perfect for that cheesesteak flavor
4 large eggs – Helps bind everything together in the casserole
60ml heavy cream (double cream) – Adds creaminess and richness to the egg mixture
2 teaspoons Worcestershire sauce – Brings umami and a touch of tang

Optional Add-ins: Sliced mushrooms, jalapeños, or shredded mozzarella for extra cheese pull.

Let’s Get Started

Here’s how to put it all together, step-by-step — it’s fast, simple, and seriously tasty.

1. Preheat and Prep

Start by preheating your oven to 180°C (350°F). Lightly grease a medium-sized casserole dish or baking dish and set it aside.

2. Brown the Beef

In a large skillet over medium heat, cook the ground beef until fully browned, breaking it up with a spoon as it cooks — about 6–8 minutes. Drain excess grease if needed.

3. Sauté the Veggies

To the same skillet, add chopped bell peppers, onions, and garlic. Cook for 5–7 minutes until the vegetables soften and become fragrant. Stir in the seasoned salt and Worcestershire sauce. Return the cooked ground beef to the skillet and mix everything well.

4. Prepare the Egg Mixture

In a mixing bowl, whisk together the eggs and heavy cream until smooth. This will act as the binder for the casserole, giving it structure while keeping it tender and moist.

5. Assemble the Casserole

Transfer the beef and veggie mixture into your prepared baking dish. Pour the egg mixture evenly over the top. Lay the provolone slices on top, slightly overlapping to ensure full coverage.

6. Bake

Place the casserole in the oven and bake for 25–30 minutes, or until the eggs are set and the cheese is bubbly and golden around the edges.

7. Cool and Serve

Let it rest for about 5 minutes before slicing. Serve hot and enjoy all that cheesy, savory goodness.

Servings and Pairing

This casserole makes 4–6 hearty servings, depending on portion size.

Great Pairings:

Simple Side Salad: A crisp green salad with vinaigrette balances the richness.
Roasted Veggies: Think broccoli, cauliflower, or zucchini.
Keto Bread Rolls: For those who still crave a bit of “sandwich” feel.
Cauliflower Rice or Mashed Cauliflower: Makes it a full low-carb meal.

Want to serve it like a sub? Spoon the hot casserole into hoagie rolls for a more traditional (but indulgent) take.

Variations

Love to experiment? Here are some tasty ways to switch things up:

Mushroom Philly Casserole: Add 1 cup of sliced mushrooms with the bell peppers for an earthy flavor.
Spicy Version: Toss in a diced jalapeño or a dash of red pepper flakes for heat.
Different Cheese: Swap provolone for mozzarella, Swiss, or even pepper jack.
Double the Cheese: Add a layer of shredded cheese beneath the provolone for extra gooeyness.
Lower Fat: Use lean ground beef or ground turkey and swap heavy cream for half-and-half.

Storage Tips

Refrigerator: Store leftovers in an airtight container for up to 4 days.

Freezer: Let the casserole cool completely before wrapping tightly and freezing. It’ll keep well for up to 2 months.

Reheating: Warm slices in the microwave or oven at 160°C (325°F) until heated through. If frozen, thaw overnight in the fridge first.

Make-Ahead Tip: Prepare the beef/veggie mixture a day ahead, assemble before baking for quick weeknight cooking.

FAQs

Can I use shredded cheese instead of slices?

Yes! Shredded provolone, mozzarella, or cheddar all work well — just use about 1½ to 2 cups.

Is this recipe keto-friendly?

Absolutely. It’s naturally low in carbs, high in fat and protein — ideal for a keto diet.

Can I substitute ground turkey?

Definitely. It will be a bit leaner, so you may want to add a touch of olive oil to keep it moist.

Do I need to use heavy cream?

Heavy cream gives the richest texture, but you can use milk or a dairy-free alternative if preferred.

How do I make this vegetarian?

Swap the beef for a plant-based ground meat alternative and adjust seasonings to taste.

Final Thoughts

Philly Cheesesteak Casserole is a winner in every sense — easy to make, full of flavor, and a guaranteed crowd-pleaser. It captures everything you love about the classic sandwich and transforms it into a cozy, low-carb meal that works for busy weeknights or family dinners alike.
