Can I Use Ground Beef Instead of Steak?

For superior texture, I recommend reheating this recipe in the oven. If you prefer, you may also reheat it in the microwave.

Can This Recipe Be Made Ahead?

You can make this up to one day ahead and cook it just before serving. Leftovers will keep for three or four days in a sealed container in the refrigerator.

Reheating

For superior texture, I recommend reheating this recipe in the oven. If you prefer, you may also reheat it in the microwave.

Freezing

It can be frozen for about three months, but note that there will be a slight decline in the overall texture.

Tips and Tricks

• If you want softer vegetables that are lightly blackened, feel free to cook them longer before putting the casserole together.

Variations

• Add ¾ cup sliced sautéed mushrooms.
• If you like, poblano peppers are also great here.
• Cheddar cheese will also work here.

How to Make Keto Philly Cheesesteak Casserole

First, preheat your oven. While the oven is preheating, heat the oil in a large skillet over medium-high heat. Add the steak and cook until browned. Remove from the heat and chop.

Add the onions and peppers to the skillet and cook for 6 minutes, until softened. Add the garlic powder and season to taste with salt and pepper. Toss the vegetables with the steak and remove from heat.

While the steak and vegetables are cooking, melt the butter in a saucepan and add the broth. Bring to a simmer over medium-high heat. Reduce the heat to medium and add the cream cheese. Whisk to incorporate as the cheese melts.

Once the cream cheese is melted, reduce the heat to low and add half of the provolone cheese. Cook until the cheese is melted and the sauce has thickened.

Add the cheese to the steak mixture and stir to combine. Transfer to a 9 x 9 casserole dish and top with the remaining cheese.

Bake for 30 minutes, until bubbly.
