This casserole comes together in under an hour and can be prepped entirely in advance, making it a dream for busy families. It is flexible enough to customize with your favorite keto twists and rich enough in flavor to satisfy non-keto eaters.

Serving and Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to four days. For best results, reheat in the oven at 350 degrees Fahrenheit until warmed through, about 15 minutes. You can also microwave individual portions for 2 to 3 minutes.

To freeze, allow the casserole to cool completely, then wrap tightly in plastic wrap followed by foil. Freeze for up to three months. Thaw overnight in the refrigerator and reheat in the oven. You can also prep the entire dish ahead of time and refrigerate unbaked for up to 24 hours before baking.

Serving Size: 1 portion

Ingredients

  • 1 pound thinly sliced beef sirloin or shaved steak
  • 1 tablespoon olive oil
  • 1 green bell pepper sliced
  • 1 red bell pepper sliced
  • 1 yellow onion sliced
  • 2 cloves garlic minced
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon paprika
  • 4 ounces cream cheese softened
  • 1 cup shredded mozzarella cheese
  • 6 slices provolone cheese
  • 1 tablespoon butter

Equipment

  • Large skillet
  • 9×13 inch casserole dish
  • Cutting board
  • Chef’s knife
  • Mixing spoon
  • Measuring spoons
  • Oven mitts

Instructions

  1. Step 1: Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch casserole dish with butter or a spritz of cooking spray. This prevents sticking and helps that cheesy crust stay intact.
  2. Step 2: In a large skillet over medium heat, add the olive oil. Once hot, toss in the sliced bell peppers and onions. Sauté for 6 to 8 minutes, stirring occasionally, until they are soft and sweet with a hint of golden caramel color. Take your time here—the flavor payoff is worth it. Transfer to a bowl and set aside.
  3. Step 3: In the same skillet, add in the sliced beef. Season with salt, black pepper, paprika, and the minced garlic. Cook for about 5 to 7 minutes until browned and fully cooked. Avoid overcrowding the pan so the beef browns instead of steams.
  4. Step 4: Lower the heat and stir in the cream cheese. It helps to cut it into smaller chunks so it melts faster. Mix until creamy and well incorporated into the beef—you want a silky filling.
  5. Step 5: Add the sautéed vegetables back into the skillet and stir until everything is evenly combined. This is your moment to sneak in any extras like chopped mushrooms or a few red pepper flakes.
  6. Step 6: Transfer the mixture into your prepared casserole dish, smoothing it out evenly with the back of your spoon.
  7. Step 7: Sprinkle the shredded mozzarella evenly over the top. Then lay slices of provolone across the top to completely cover the casserole. This creates the signature cheesesteak cheesiness.
  8. Step 8: Bake uncovered for 15 to 20 minutes until the top is golden and bubbly. If you like a crisp cheese crust on top, switch to broil for the last 2 to 3 minutes. Watch it closely.
  9. Step 9: Let it cool for at least 5 minutes before serving. This helps the cheesy layers settle. Sprinkle with fresh parsley if you are feeling fancy.

FAQ

Can I prepare this casserole ahead of time?

Yes. You can fully assemble the unbaked dish a day in advance and store it in the refrigerator. Let it rest at room temperature for 20 minutes while the oven preheats, then bake as directed.

What is the best type of beef for this recipe?

Thinly sliced sirloin or shaved ribeye offers the most authentic cheesesteak flavor. If unavailable, ground beef or leftover roast beef work well too—just adjust cooking time accordingly.

Will this still taste good without provolone cheese?

Definitely. While provolone is classic, mozzarella, Swiss, white American, or even cheddar will work. You can even do a mix for deeper flavor. Just choose cheeses that melt well and keep it keto.
