Philly Cheesesteak Soup
Have you ever had a Philly cheesesteak sandwich? My mouth is watering just picturing the crusty roll filled with sliced beef, onions and cheese sauce! So yummy right?
This twist on the original uses all the deliciousness of the sandwich minus the carbs! My Philly cheesesteak soup recipe is Keto and low carb but, above all, it is insanely delicious.
It is also a great way to use any leftovers from a beef roast – I used sliced brisket from my recent Slow Cooker Brisket recipe.
Here’s what you will need
I cooked this soup in my trusty Greenpan Dutch Oven but you can also make it in a slow cooker.
- Butter or olive oil
- Onion and garlic
- Green bell peppers
- Button mushrooms
- Beef or chicken broth – I used homemade chicken broth.
- Thinly sliced roast beef – you can use deli roast beef if you like
- Cream cheese or heavy cream
- Grated cheddar cheese (Provolone cheese is more traditional)
- Plenty of chopped parsley
HOW TO MAKE PHILLY CHEESESTEAK SOUP
Full measurements and instructions can be found on the printable recipe card at the bottom of the page. Please take a look at the steps and video before attempting this recipe!
Heat the butter in a large pot, over medium heat. Add the onions, peppers, mushrooms and garlic and cook, stirring, for 5-10 minutes.
Stir in the salt and pepper once the vegetables have softened – if you are using salted stock / broth you can leave the salt out.
Add the beef broth and sliced beef, stirring everything together. Bring to a boil then lower the heat and simmer for 10-15 minutes.
Put the cream cheese in a measuring jug and add a ladleful of the broth from the pot. Use an immersion blender to combine.
Stir the cream cheese into the soup together with the grated cheese, stirring until cheese melts. Taste and season with salt and pepper if needed.
Divide into warm bowls and garnish with the chopped parsley and some extra grated cheese if you like. Serve with a slice of my keto bread.
Slow Cooker Philly Cheesesteak Soup
Cooking this Philly cheese steak soup in your slow cooker is super easy too. Sauté the vegetables – if your Crock Pot allows for searing then one pot less to wash up! – and add to your slow cooker.
Add the rest of the ingredients apart from the cream and cheese and cook on low for 6 hours. Blend the cream cheese with a little of the soup and stir into the soup together with the cheese before serving.
