This Philly Cheesesteak Dip is SINFULLY delicious. This easy dip is packed with crispy steak, tangy provolone cheese, mozzarella, and gooey white American cheese. It's studded with green peppers, mushrooms, and a creamy sauce, you can't resist.
Place the steak in the freezer for about 20 minutes. Use a sharp knife to cut the steak paper thin. Cut into smaller pieces. Season the steak with salt and pepper.
Heat a large skillet over a medium-high heat. Add olive oil to the skillet. Sear steak until crispy, brown, and cooked through. If needed, chop into smaller pieces. Remove from the pan and set aside.
Reduce the heat to medium. Add another 2 teaspoons olive oil to the pan. Add onions and peppers. Saute until they start to soften, about 2 minutes. Add steak, cheeses, half and half, and chicken stock. Heat on low, stirring every few minutes until the cheese melts.
If needed, add a little bit more half and half or chicken stock to loosen the sauce up. Season with salt and pepper. Serve with crusty bread.
