Slow Cooker Philly Steak Sandwich Recipe

Beef sirloin: Thinly sliced to ensure tenderness and quick cooking in the slow cooker.

Green bell pepper: Adds a fresh, slightly sweet flavor and a bit of crunch to the sandwich.

Onion: Sliced to blend seamlessly with the beef and peppers, providing a savory depth.

Garlic: Minced to infuse the dish with a robust, aromatic flavor.

Beef broth: Used to keep the meat moist and flavorful during the slow cooking process.

Worcestershire sauce: Adds a tangy, umami-rich depth to the beef mixture.

Salt: Enhances the overall flavor of the dish.

Black pepper: Provides a subtle heat and additional seasoning.

Hoagie rolls: The perfect vessel for holding the delicious beef mixture and melted cheese.

Provolone cheese: Melts beautifully over the beef, adding a creamy, savory finish to the sandwich.

To ensure the beef sirloin is tender and flavorful, consider marinating it overnight in a mixture of beef broth, worcestershire sauce, and minced garlic. This will allow the flavors to penetrate the meat more deeply, resulting in a more savory and succulent Philly steak sandwich. Additionally, when slicing the green bell pepper and onion, aim for uniform thin slices to ensure even cooking and a consistent texture throughout the sandwich.

• beef sirloin - Substitute with chicken breast: For a lighter option, chicken breast can be used. It will still absorb the flavors well and provide a different but delicious taste.

• green bell pepper - Substitute with red bell pepper: Red bell peppers are sweeter and can add a different flavor profile while maintaining the texture.

• onion - Substitute with shallots: Shallots have a milder and slightly sweeter taste compared to onions, which can add a subtle flavor difference.

• garlic - Substitute with garlic powder: If fresh garlic is not available, garlic powder can be used. Use ¼ teaspoon of garlic powder for each clove of garlic.

• beef broth - Substitute with chicken broth: Chicken broth can be used as a substitute and will still provide a rich flavor to the dish.

• worcestershire sauce - Substitute with soy sauce: Soy sauce can provide a similar umami flavor, though it will be slightly different in taste.

• salt - Substitute with soy sauce: Soy sauce can also be used to add saltiness and umami flavor, reducing the need for additional salt.

• black pepper - Substitute with white pepper: White pepper has a slightly different flavor but can still provide the necessary heat and spice.

• hoagie rolls - Substitute with baguette: A baguette can be used as an alternative bread option, providing a similar texture and structure.

• provolone cheese - Substitute with mozzarella cheese: Mozzarella has a mild flavor and melts well, making it a good substitute for provolone.

• Allow the beef mixture to cool completely before storing. This helps prevent condensation, which can lead to sogginess.

• Transfer the beef mixture into an airtight container. Make sure to use a container that is appropriately sized to minimize air exposure.

• Store the container in the refrigerator if you plan to consume the leftovers within 3-4 days. For longer storage, place the container in the freezer.

• If freezing, label the container with the date to keep track of freshness. The beef mixture can be frozen for up to 2-3 months.

• When ready to use, thaw the beef mixture in the refrigerator overnight if frozen.

• Reheat the beef mixture in a saucepan over medium heat until warmed through. You can also use the microwave, heating in 1-minute intervals and stirring in between.

• To maintain the texture of the hoagie rolls, store them separately at room temperature in a bread box or a resealable plastic bag. If you need to store them longer, freeze the rolls in a resealable plastic bag for up to 1 month.
