Philly Cheese Steak Crock Pot Recipe

Round steak, peppers, onion, and an Italian seasoning packet go into the crock pot in the morning. Eight hours later, the meat is fork-tender and loaded with flavor — pile it onto hoagie buns, lay two slices of provolone on top, and run it under the broiler for two minutes. Hot Philly cheese steak sandwiches on a weeknight, with almost zero hands-on time.

What Is This Recipe?

A Philly cheesesteak is a hot sandwich of thinly sliced beef, cooked peppers and onions, and melted cheese — traditionally made on a flat-top grill in Philadelphia. This version does the meat and vegetables in a slow cooker, using beef round steak and a packet of dry Italian dressing mix as the seasoning. The result is deeply flavored, pull-apart tender beef cooked in a savory broth with peppers and onions, all ready to scoop onto a hoagie bun.

It’s not a traditional Philly cheesesteak — but it’s a legitimately great sandwich that comes together on a busy weeknight without any afternoon cooking. The slow cooker does all the work, and you get six sandwiches from one batch.

Ingredient Breakdown

Beef Round Steak (2 1/2 to 3 pounds)

Round steak is lean and budget-friendly but tough if cooked fast — that’s the whole point of the slow cooker here. Eight hours on low breaks it down completely into tender, shreddable beef. Slice it thin before cooking, or ask your butcher to do it. If you can’t find round steak, chuck roast is an excellent substitute and shreds even more easily. I’ve used both and both work — chuck is richer, round is leaner.

Green Peppers (2, sliced thin)

Slice them thin so they cook down into the beef and onion mixture rather than staying in big pieces. Green peppers have a slightly bitter flavor that balances the richness of the beef and cheese — that’s why they’re traditional. Red or yellow peppers work and are sweeter; a mix of colors looks great and tastes good, but it changes the flavor slightly.

Onion (1, sliced thin)

Goes in raw and cooks down completely in the broth. Don’t skip it — onion is half the flavor base of this filling. Yellow onion is standard; white or sweet onion also work. By hour eight you won’t be able to pick out a distinct piece of onion, but you’ll taste it in every bite.

Dry Italian Dressing Mix (1 envelope)

The ingredient that makes this recipe so easy. One packet contains a balanced blend of garlic, herbs, and salt — pour it straight into the crock pot. I’ve tried building the same flavor with individual spices and the packet is better. It’s the kind of shortcut that feels like cheating and tastes like you didn’t. Hidden Valley, Good Seasons, and store brands all work equally well.

Beef Stock (2 cups)

The braising liquid. Don’t reduce this amount — the slow cooker needs the liquid to prevent the meat from drying out over eight hours. It develops into a rich, flavorful broth as everything cooks together, and you can use it to moisten the meat when you’re assembling sandwiches.

Black Pepper (2 tsp) and Garlic Salt (3 tsp)

Added on top of the Italian dressing mix. The garlic salt reinforces the garlic flavor already in the packet; the black pepper adds background heat. Don’t skip both — the seasoning packet alone undersells the final flavor. Together they make a noticeable difference.

Hoagie Buns (6)

Bun quality matters more than most people give it credit for here. Get the best hoagie buns you can find — a soft interior with a slightly firm exterior holds up to juicy meat and melted cheese without disintegrating. Avoid hamburger buns; they’re too small and too soft. Sub rolls, Italian hero rolls, and bolillo rolls all work.

Provolone Cheese (12 slices)

Two slices per sandwich. Provolone melts smoothly, has a mild tangy flavor that pairs well with the beef, and holds up to the broiler. Use deli-sliced provolone — pre-shredded won’t give you the same melt. American cheese is the most authentic Philadelphia choice and melts the smoothest if you want to go that route. Either way, don’t skip the broiler step. That’s what melts the cheese into the meat instead of just laying on top of it.

How to Make It

1. Spray the crock pot with cooking spray.
2. Cut the round steak into thin slices. Brown in a hot pan for just a minute — you’re getting color, not cooking it through. This step adds real depth; don’t skip it if you have five minutes.
3. Add the browned beef, green peppers, onion, beef stock, garlic salt, black pepper, and the Italian dressing mix packet to the crock pot. Give it a stir to distribute the seasoning. Put the lid on.
4. Cook on low for 8 hours. By the end, the beef should be fall-apart tender and the peppers and onions will have cooked down into the broth. The smell when you lift the lid is worth the wait.
5. Line a baking sheet with foil. Spoon the meat and veggie mixture onto sliced hoagie buns. Don’t be stingy — load them up. Set the buns open-faced on the baking sheet.
6. Lay 2 slices of provolone on each sandwich, overlapping to cover the meat.
7. Broil on low for 2-3 minutes until the cheese is melted and the bun edges start to toast. Watch it — provolone goes from melted to overcooked faster than you expect. The moment the cheese starts to bubble, it’s done.

Serving Suggestions

• French fries or potato wedges — the classic cheesesteak side; bake a frozen bag while the sandwiches are under the broiler
• Simple coleslaw — creamy coleslaw adds crunch and cuts the richness of the beef and cheese
• Soup — tomato soup or French onion alongside a half sandwich is a great cold-weather pairing

Storage and Make-Ahead

Refrigerator: Store the cooked meat and vegetable mixture (without buns or assembled sandwiches) in an airtight container for up to 4 days. Keep the buns and cheese separate.

Reheating: Warm the meat mixture in a saucepan over medium-low heat or in the microwave in 60-second intervals until hot. Assemble and broil the sandwiches fresh — don’t reheat them already built.

Freezer: The meat mixture freezes well for up to 3 months. Cool completely, then freeze in a zip-top bag with as much air removed as possible. Thaw overnight in the refrigerator and reheat before serving.

Frequently Asked Questions

Do I have to brown the meat first?

I’d push back on skipping it. The browning step takes five minutes and adds a layer of flavor — color, depth, the toasty edges that survive the long braise — that you simply don’t get from a raw roast going straight into the slow cooker. If you’re genuinely pressed for time, it still works without it. But if you have five minutes in the morning, use them here.

Can I use a different cut of beef?

Yes. Chuck roast is an excellent substitute — more fat marbling and it shreds even more easily after 8 hours. Flank steak works but cooks faster; check at 6 hours. Round steak is the original choice because it’s affordable and the long braise handles the toughness. All of them work with this seasoning.

What if I don’t have Italian dressing mix?

Make your own: 1 teaspoon each of garlic powder, onion powder, dried oregano, and dried basil, plus 1/2 teaspoon salt and 1/2 teaspoon sugar. It won’t be identical but it gets close. Ranch seasoning is also a solid substitute — changes the flavor but works well with this method.

Can I cook this on high instead of low?

Yes — cook on high for 4-5 hours. Low and slow is preferred because it gives the tough connective tissue in round steak more time to break down properly, but high for 4-5 hours works when you need dinner faster.

What cheese is most authentic?

In Philadelphia, the traditional choice is American cheese or Cheez Whiz — not provolone. American melts the smoothest and is the easiest to work with under the broiler. Provolone has become the most common home-cook choice and it’s what I use. Use whichever you prefer; the beef is the star either way.

Can I make this for a crowd?

Yes, easily. Double it and use a 6-quart or larger crock pot. Keep the meat warm on the low setting and let people assemble their own sandwiches. This is one of the best slow cooker options for game day or casual entertaining — the work is done before anyone arrives.

A Note From Kate

This is one of those slow cooker dinners that surprises people who think crock pot food is somehow less than — the flavor here is deep and real, not watered down. The Italian seasoning packet is the kind of shortcut that feels like cheating but tastes like you put in real effort. I started making this in the fall when the slow cooker comes out for the season, and it’s stayed on the rotation ever since. Six sandwiches, almost no afternoon effort, and the leftovers are genuinely good the next day. Hard to argue with that.
