8 oz cream cheese (1 package), softened

Step-by-Step Instructions
-
Preheat and Prep
Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray to prevent sticking. -
Sauté the Veggies
In a large skillet, heat olive oil over medium heat. Add diced onions and bell peppers. Cook for 5-6 minutes until softened. Add minced garlic and cook for another 30 seconds. -
Cook the Beef
Add ground beef to the skillet. Season with salt and pepper. Cook until fully browned, about 7-8 minutes, breaking it up as it cooks. -
Make It Creamy
Stir in the Worcestershire sauce, then reduce heat to low. Add softened cream cheese and stir until completely melted and incorporated into the beef and veggie mixture. -
Transfer to Baking Dish
Spread the creamy beef mixture evenly into the prepared baking dish. -
Top with Cheese
Layer the provolone slices over the beef. Sprinkle mozzarella evenly on top. -
Bake
Bake uncovered for 20-25 minutes, until the cheese is bubbly and golden. -
Rest and Serve
Let the casserole rest for 5 minutes before serving. This helps everything set up nicely and makes it easier to slice.
Kitchen Equipment You’ll Need
-
Large skillet

9×13 baking dish

Sharp knife and cutting board
-
Cheese grater (if shredding your own mozzarella)

Oven-safe gloves or mitts
Recipe Tips and Variations
Add a Crunchy Topping
While this is a low-carb dish, if you’re not strictly keto, try topping the casserole with a handful of crushed pork rinds or almond flour breadcrumbs before baking for a crunchy twist.
Use Steak Instead of Ground Beef
Swap out the ground beef for thinly sliced ribeye or sirloin for a more authentic Philly cheesesteak vibe. Sear the steak slices quickly in the pan before adding the rest of the ingredients.
Veggie Boost
Add mushrooms, spinach, or zucchini for extra nutrients and volume. Just sauté them with the peppers and onions.
Cheese Substitutions
-
Instead of provolone: Try white American, gouda, or Swiss.
-
Instead of mozzarella: Use cheddar, Monterey Jack, or a Mexican blend.
Spice It Up
Add a pinch of red pepper flakes, jalapeños, or a dash of hot sauce for a spicy version.
How to Store and Reheat Leftovers
Refrigerator:
Store leftovers in an airtight container for up to 4 days.
Freezer:
Freeze individual portions in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
To Reheat:
Microwave on medium power in 1-minute intervals until heated through, or reheat in a 325°F oven for 10-15 minutes.
Pro Tip: If the casserole seems dry after reheating, add a spoonful of sour cream or a splash of cream to revive the creamy texture.

Frequently Asked Questions (FAQ)
Can I make this casserole ahead of time?
Absolutely! Assemble everything (without baking), cover, and refrigerate up to 24 hours ahead. Bake just before serving.
Is this casserole keto?
Yes, it’s very keto-friendly. It’s high in protein and fat while keeping the carbs low. Be sure to use full-fat cream cheese and check your Worcestershire sauce for hidden sugars.
Can I use turkey or chicken instead of beef?
Yes, ground turkey or chicken are excellent lean substitutes. The cream cheese still keeps it rich and satisfying.
What’s the best way to soften cream cheese quickly?
Cut it into small cubes and let it sit at room temperature for 15–20 minutes. You can also microwave it for 10–15 seconds (just be careful not to melt it).
Do I need to cover the casserole while baking?
No, bake it uncovered so the cheese topping gets bubbly and slightly golden.
