I think it’s so fun to turn sandwiches into casseroles, don’t you? (My most popular one is chicken bacon ranch casserole!) This low carb keto philly cheesesteak casserole recipe is just that – the sandwich turned into a comforting casserole. No bread required.

Low carb philly cheesesteak casserole with cream cheese, ground beef, sauteed peppers and onions is the classic cheesesteak combo, topped off with a layer of melt-y provolone cheese. And since it’s ready in 30 minutes, using simple ingredients, it’s easy to whip up last minute on a weeknight.

What Is Philly Cheesesteak Casserole?

Low carb philly cheesesteak casserole takes all of the flavor from the iconic sandwich and puts it into casserole form!

This keto cheesesteak casserole packs major flavors, from creamy and cheesy ground beef, to sauteed onions and peppers, to a melty layer of provolone cheese. You definitely won’t miss the bread!

How To Make Philly Cheesesteak Casserole

Let’s make this keto philly cheesesteak casserole recipe! It comes together in just 30 minutes:

Brown ground beef. Saute beef in a large saute pan, breaking up with a spatula. Season with salt and pepper.

Saute veggies. Add bell peppers and onions to pan. Season with Italian seasoning, smoked paprika, and garlic powder. Saute until veggies are soft.

Add cream cheese. Stir in cream cheese and broth until smooth and melted.

TIP: You can adjust the amount of cream cheese to taste here. Add an additional 2 ounces if you want it super creamy.

Assemble. Transfer to a baking dish and top with a layer of provolone cheese.

Bake casserole, until cheese is melted.

TIP: Broil casserole for a few minutes before serving to brown the cheese, as pictured here.

Can You Use Steak Instead of Ground Beef?

Absolutely! The process would be very similar. You’d simply cook your steak separately first. Here’s how:

Cook the steak separately. Try my method for sirloin steak in the oven (and slice against the grain after cooking) OR you can slice raw flank steak thinly first and then saute the pieces briefly until cooked through. Since steak dries out more easily than ground beef, set it aside to keep warm and don’t keep it in your pan.
Saute the bell peppers and onions on their own. Add steak back to the pan only toward the end.
Stir in seasonings, cream cheese and broth. Saute for a minute or two with the seasonings, then stir in the cream cheese and broth.
Transfer to casserole dish and proceed with the recipe the same way.

Can You Make Philly Cheesesteak Casserole Ahead?

Yes, you can make this low carb philly cheesesteak casserole recipe ahead of time. Casseroles are one of the best foods to prep ahead!

You have a couple of options:

Meal prep the main components. Brown the ground beef, and slice the onions and bell peppers. Store them separately in the fridge to time the day-of.
Make and assemble the casserole. Instead of baking it, store it covered in the refrigerator. When ready to eat, simply bake as directed. You may need to add approximately 10 more minutes to the baking time, just to heat it through.

If you pre-assemble the casserole or if you store leftovers, either way it will last in the fridge for about 5 days. To reheat your keto ground beef philly cheesesteak casserole if it was baked previously, you can either use the microwave or a 350 degrees F oven, until hot.

Can You Freeze Cheesesteak Casserole?

Yes, you can also freeze this keto low carb philly cheesesteak casserole. Assemble it without baking, wrap tightly with foil, and freeze for up to 3 months.

Let thaw in the refrigerator overnight and bake in a 350 degree F for approximately 20 minutes, until hot. If you need to bake from frozen, it will take a lot longer (at least 40-50 minutes) and you’ll need to cover it to prevent burning the cheese from being in the oven so long.

Made this for dinner tonight, and while it tasted pretty good, it required a tremendous amount of effort (more than it usually would) because I am sick and exhausted. I was grateful to have my husband slice the onion. One thing does concern me about this recipe, with regard to it being keto.

Can this be prepared ahead of time, beef cooked put in fridge and cooked in oven later or even frozen?

I needed a quick dish tonight for dinner. From prep to plate, we were able to eat in less than an hour. This dish was DELICIOUS! It was so creamy and flavorful. I doubled the smoked paprika and went with 6 ounces of cream cheese. Everyone loved it. This Philly Cheesesteak Casserole will definitely be on our new rotation.

I love this recipe! It was amazing! I’m disabled but I persevered. It was a two day process and well worth the pain. I don’t like to use frozen pepper strips, so I cut my own and that took a along time. Thank you for all your flavorful recipes!

The flavor was so good! However, I wish I had drained the grease/fat off the meat. Husband didn’t mind it but as a personal preference I will definitely drain next time. Otherwise, it was great! We added fresh mushrooms and extra bell peppers.
