High Protein Low Carb Philly Cheesesteak Casserole Recipe

Introduction

Looking for a meal that’s absolutely loaded with flavor, packed with protein, but won’t derail your low carb lifestyle? This High Protein Low Carb Philly Cheesesteak Casserole delivers all the steakhouse satisfaction of a classic Philly cheesesteak in a warm, melty, and utterly craveable casserole. Thanks to lean steak, a bounty of peppers, cheese, and clever low-carb swaps, this weeknight dinner staple is hearty enough to please any crowd while keeping your macros in check.

Why This Philly Cheesesteak Casserole Is a Game Changer

Unlike traditional recipes that pack in the bread, this casserole ditches the carbs and doubles down on the protein. It’s the ultimate choice for anyone seeking a filling, nutritious meal that still tastes like an indulgent treat. Each bite delivers the savory punch of seared beef, sautéed veggies, and gooey melted cheese, all without the carb-heavy roll—making it a perfect meal-prep powerhouse or easy family favorite.

High Protein Filling, Low Carb Goodness

At the heart of this dish is a blend of thin-sliced steak—think sirloin or flank—sautéed until tender alongside vibrant green peppers, onions, and mushrooms. A mixture of creamy Greek yogurt and egg binds it all together, mimicking that classic Philly cheesesteak richness without the extra carbs. Topped with provolone and mozzarella, you’ll get golden, bubbling cheese in every spoonful.

Making Your Casserole Stand Out

To take the flavors up a notch, a quick seasoning of garlic, Worcestershire sauce, salt, and pepper is all you need. By prepping everything in one skillet before baking, you layer on flavor in every step. The finishing touch? A broil at the end to brown the cheese and add extra texture.

Serving Suggestions

Pair this Philly cheesesteak casserole with a simple green salad or roasted low-carb veggies for a truly complete meal. You can even serve it alongside cauliflower rice or fill bell pepper halves for a fun twist. Don’t forget a side of pickles or hot sauce for an added punch!
