Keto Philly Cheesesteak Casserole (yum!)

By Bree

Today I’m going to be sharing a recipe for making a Philly cheesesteak keto casserole that will absolutely change the way you approach keto casseroles. It’s packed full of protein and quality fats, not to mention the flavorful combination of herbs and seasonings.

Gooey Philly Cheesesteak Keto Casserole

When i’m craving a comfort food, and want an easy meal, I love deconstructing a classic recipe and turning it into a casserole like this keto cheesesteak casserole. If you’re looking for more ‘classics turned casserole’, also try my Cheeseburger Casserole, Buffalo Chicken Casserole and Keto Big Mac Casserole (yes, you heard me right, lol).

How to Make a Philly Cheesesteak Keto Casserole

I love recipes that combine two or more of my favorite foods into one mega delicious superfood. That’s exactly what the recipe I’m sharing today does. Here’s my recipe:

  • Preheat the oven. Preheat your oven to 350℉ and prepare the cooking skillet. Heat some olive oil in the skillet.
  • Cook the onion and beef. Saute the onion first for about 2-3 minutes then add the ground beef. Cook the beef until it’s brown, then add the bell peppers.
  • Add the cream cheese. Add the cream cheese and stir to combine.
  • Season the mixture. Add your Italian seasoning, garlic powder, smoked paprika, and salt and black pepper to taste.
  • Stir. Stir everything together until well combined.
  • Prepare for baking. Transfer the mixture to a baking dish and top with Provolone cheese.
  • Bake. Bake the casserole for 15-20 minutes or until the cheese has melted.
  • Cool. Remove from the oven and allow the casserole to cool for 10 minutes before serving.

Can I Freeze This Keto Casserole?

In the unlikely event that you have any leftovers of this casserole (once you get your first taste you’ll see exactly what I mean!), you can definitely freeze them. It’s also a great candidate to make ahead and then freeze until you’re ready to cook it.

If you’re freezing leftovers, you’ll want to follow these steps to store and reheat:

  • Make sure you have allowed them to cool completely. Leave it in the dish while it’s cooling.
  • Divide the casserole into meal sized portions. Transfer into airtight containers and label them with the day you cooked them. You’ll be able to keep your leftovers frozen like this for up to one month.
  • To reheat, leave the container out to thaw for 3-4 hours. Simply leave it out at room temperature.
  • Heat it for 1-3 minutes. Microwave it on high for 1 minute, or put it in the oven on broil for 2-3 minutes or until the cheese has melted again.

  • Are Keto Casseroles Like This Healthy?

    Casserole can just as easily be a healthy, nutrient-dense dish as it can be an unhealthy, carb-loaded dish. It all comes down to the ingredient selection used in any specific recipe. By using low carb keto-friendly foods, it can be rather easy to make a healthy casserole dish.

    As for this particular Philly cheesesteak casserole recipe, you can breathe a sigh of relief right now because it’s indeed good for you. As a matter of fact, here are a few benefits it offers:

    • Excellent source of antioxidants. This casserole is loaded with ingredients that are rich in disease-fighting antioxidants. The olive oil, bell peppers, onion, and the herbs and seasonings used to make this recipe are all great sources of antioxidants.
    • Packed full of protein. Adding lean ground beef into this casserole doesn’t just provide it with a ton of protein. It also provides an abundance of saturated animal fats, dietary cholesterol, B-complex vitamins, and essential minerals like zinc.
    • Incredibly satiating. Eating nutrient-dense meals like this casserole that are made with nothing but real, whole foods works great for satiating hunger. You definitely won’t be feeling hungry again for quite a while after eating this casserole.

    1. My family tried this recipe and it was delicious! Easy to prepare and even my kids liked it. I added a side of noodles for the kids to eat with this. Next time we will probably put in a bigger baking dish (like a 9×13) so we can add more cheese on top. Thanks for a great dinner recipe!

    2. Hi !
      HUsband and I are new to keto. So tried this recipe and really liked it.
      How many servings for the 9×13 pan? I cut it into 8 pieces.
      Just like to write down what the carbs and calories are for one serving. So 1/8 of the 9×13 sound right?
