Keto Philly Cheesesteak Casserole

This Keto Philly Cheesesteak Casserole brings all the bold, savory flavors of a classic Philly cheesesteak into a cozy, oven-baked dish—without the carbs.

It’s hearty, satisfying, and tastes just like comfort food should—warm, cheesy, and full of flavor.

Is this good for weight loss?

Yes—this recipe supports weight loss on a keto diet because it’s high in protein and healthy fats while staying very low in net carbs. The protein helps keep you full longer, while the low-carb ingredients help maintain ketosis and reduce cravings—making it easier to stay on track without feeling deprived.

Is this keto or not? And why?

This dish is 100% keto-friendly. It uses low-carb vegetables (bell peppers and onions in moderation), high-fat cheese, and protein-rich beef. There’s no bread or starch involved, keeping net carbs low (about 4–5g per serving), which fits perfectly into a ketogenic diet.
