Cooking Tips for the Best Philly Cheese Steak Casserole

• Use lean ground beef – This prevents the dish from being too greasy while keeping it full of flavor.
• Experiment with different cheeses – If you don’t have provolone, try cheddar, mozzarella, or Swiss for a different taste.
• Make it spicier – Add extra hot sauce, red pepper flakes, or diced jalapeños for some heat.
• Save time with meal prep – You can cook the beef and veggies ahead of time for quick assembly.

Substitutions and Variations

Low-Carb & Keto Options

If you’re following a low-carb or keto diet, this casserole is already a great option. However, you can tweak it further:

• Use ground turkey instead of beef for a leaner option.
• Swap bell peppers for mushrooms or zucchini for different textures.
• Serve over cauliflower rice to make it even heartier.

Cheese Variations

While provolone is the classic choice for Philly cheesesteaks, you can switch things up with:

• Cheddar Cheese – For a sharper, more robust flavor.
• Pepper Jack – If you like a bit of spice.
• Swiss Cheese – Adds a mild, nutty taste.

Serving Ideas

• Classic Philly Style – Serve the casserole inside a toasted hoagie roll for a more traditional experience.
• With a Side Salad – A fresh green salad balances the richness of the casserole.
• Over Roasted Veggies – Pairs well with roasted asparagus, Brussels sprouts, or zucchini.
• With Garlic Bread – If you’re not concerned about carbs, garlic bread is a great side option.
