This quick and easy casserole is so delicious! I might even go as far as saying it is the BEST cheesesteak casserole recipe out there. All the authentic flavors of a Philly cheesesteak without the bun (and carbs)!

How To Make Keto Philly Cheesesteak Casserole

Step1: Heat oil in a cast-iron skillet over medium heat. (I use this 10 1/2″ skillet for this recipe.) Sear seasoned steak in two batches and set meat aside. Crowding your skillet will not allow the meat to brown well!

Step 2: Add butter to the skillet and throw in your green bell peppers, red peppers, onions, garlic, and mushrooms. (Feel free to leave a veggie out if you prefer.) Saute until the veggies are soft. Add beef broth, Braggs Aminos, Worcestershire sauce, and salt/pepper. Cover with lid and simmer for two minutes.Step 3: Add seared beef back to the pan and cook over medium heat for two more minutes. Add provolone cheese slices to the top of the steak and veggies covering as much as possible!

Step 4: Place the skillet or oven-proof pan in the oven under the broiler for 1-3 minutes or until the cheese begins to bubble and brown. Watch it closely, so it doesn’t burn! Serve hot!

Is This Philly Cheesesteak Ground Beef Casserole Recipe Keto & Low Carb?

Yes. No hoagie rolls here! This recipe is very keto-friendly and has minimal carbs. If you prefer to lessen the carbs, you can remove the bell peppers from this recipe or use less. (Half a bell pepper has 3 net grams of carbs.) If you still want a Philly Cheesesteak sandwich, a chaffle is a fantastic low carb alternative for a bun.

What Is The Best Meat For A Philly Cheesesteak?

A traditional “Philly Cheesesteak” is made with thinly sliced ribeye. Now, ribeye steaks are a bit pricey but for a good reason. The meat is quality! It has a good amount of fat and will give you a tender, juicy, and delicious steak casserole.

If you are on a budget, you can use skirt steak or sirloin steak instead! Just make sure it is THINLY SLICED. If you can’t do this properly, ask the butcher to shave your meat for you. They have the tools to do this, and I’m sure would be more than happy to do it for you.

Another meat option is to use ground beef! The flavors will still be there, and the result would still be tender and juicy. Plus, it is cost-efficient.

Tip: Ask the butcher at the grocery store to shave the ribeye for you.

How To Make This Philly Cheesesteak Skillet Ahead of Time

Follow all the steps above before you add your cheese. Then place the entire, covered, skillet in the fridge until you are ready. Warm up the steak and veggies on the stove and continue with step 3 above, add your provolone cheese and broil.

How to Store Your Casserole

Store your casserole in the skillet itself covered and keep in the fridge until your ready to reheat. You can also add the mixture to a casserole dish (see below).

Don’t have a cast-iron skillet?

If you don’t have a cast-iron skillet, you can use a regular oven-safe skillet to do the same job. Another option is to prepare the veggies and steak, as stated above. Then transfer everything to a small casserole dish (similar in size to a skillet) and layer with your provolone. Cover and refrigerate or freeze until your ready to reheat. Be careful about reheating since you do not want to overcook your steak!

Tip: Cast iron skillets are very affordable and last forever! A few that I have were my grandmothers and over 50 years old. A cast-iron skillet is a worthwhile investment and less than $20.

Can I Freeze My Casserole?

Yes. You will just need to place the cooked steak and veggies in a freezer-safe casserole dish and seal it with a lid or plastic wrap/foil. Try to find a baking dish about the size of your skillet.

Low Carb Philly Cheesesteak Casserole Variations

I do want to mention since residents from Philadelphia can get touchy about their cheesesteaks, that an authentic Philly Cheesesteak does NOT have mushrooms or peppers. Take a visit to a few of the popular cheesesteak restaurants in the area, like Pat’s or Geno’s, and all you’ll see if steak, onions, and cheese. That’s it.

So if you prefer to make it more “authentic,” you can leave the rest out. What cheese is best? Provolone vs. cheese whiz is an ongoing debate, but since cheese whiz is not keto-friendly, provolone it is!

• Use sirloin, flank steak, or even ground beef
• Omit the peppers or mushrooms
• Use a different cheese that is keto-friendly
• Add more spices like onion or garlic powder
• Fresh herbs will add a brightness to your casserole
• Add cream cheese to make a creamier casserole
