Ingredients for Low Carb Philly Cheesesteak Casserole

Here’s everything you’ll need to make this cheesy masterpiece – I promise it’s all simple stuff!

Meat: 2 lbs ground beef (85/15 works best – enough fat for flavor but not greasy)
Veggies: 1 large onion (diced), 2 bell peppers (any color, diced), 2 cloves garlic (minced)
Dairy: 8 oz cream cheese (softened!), 8 oz provolone slices, 1½ cups shredded mozzarella
Extras: 2 tbsp Worcestershire sauce, 1 tbsp olive oil, salt & pepper to taste

Ingredient Substitutions & Notes

Don’t stress if you’re missing something – here are my tried-and-true swaps:

Ground turkey works if you’re watching calories, but add extra seasoning
Dairy-free? Use almond cream cheese and vegan mozzarella shreds
Love mushrooms? Toss in 8oz sliced – just sauté them with the peppers
Warning: Go easy on watery veggies like zucchini – they’ll make the casserole soggy

The cream cheese must be SOFT or you’ll have lumpy filling – trust me on this!

How to Make Low Carb Philly Cheesesteak Casserole

Okay, let’s get cooking! This comes together so easily – just follow these simple steps:

Preheat your oven to 375°F (190°C) – do this first so it’s ready when you are!
Sauté the veggies: Heat olive oil in a large skillet over medium heat. Add onions and bell peppers, cooking until they soften (about 5 minutes). Toss in the garlic and cook for just 1 more minute – you’ll smell when it’s ready!
Brown the beef: Add ground beef, breaking it apart with your spoon as it cooks. Keep going until no pink remains – about 7-8 minutes.
Drain & mix: Carefully pour off excess fat (I tilt the skillet and use a spoon). Then stir in cream cheese and Worcestershire sauce until everything’s creamy and combined. Season with salt and pepper – taste as you go!
Layer the cheese: Transfer the mixture to a baking dish. First lay provolone slices across the top, then sprinkle mozzarella over everything. This double-cheese method is my secret for maximum meltiness!
Bake for 20 minutes until bubbly and golden. Let it rest 5 minutes before serving – I know it’s hard to wait!

Tips for the Best Low Carb Philly Cheesesteak Casserole

Here are my hard-earned tricks for casserole perfection:

Pat the cooked beef with paper towels before adding cream cheese – removes extra grease
Want crispy cheese? Broil for the last 2 minutes (watch closely!)
Letting it rest before serving helps the layers set – worth the wait!

Serving Suggestions for Low Carb Philly Cheesesteak Casserole

This casserole stands strong on its own, but here’s how I love to round out the meal:

A crisp side salad with tangy vinaigrette cuts through the richness perfectly
Roasted asparagus or green beans make a simple, elegant pairing
For crunch lovers, try crispy bacon bits or toasted almond slivers on top

Skip the bread – you won’t miss it with all this flavor going on!

Storing and Reheating Low Carb Philly Cheesesteak Casserole

Here’s the good news – this casserole tastes even better the next day! Store leftovers in an airtight container in the fridge for 3-4 days. When reheating, skip the microwave – pop individual portions in the oven at 350°F until bubbly again. That cheese will get perfectly gooey without turning rubbery. Pro tip: If the top needs reviving, a quick minute under the broiler works wonders!
