Ingredients Notes

This recipe relies on a handful of simple yet flavorful ingredients. Here’s what you’ll need to make the perfect Slow Cooker Italian Beef Sandwiches:

Beef Roast

A chuck roast is the ideal cut for this recipe. It becomes beautifully tender after hours of slow cooking. If chuck roast isn’t available, try a rump roast or bottom round roast instead.

Pepperoncini Peppers

These tangy, mildly spicy peppers are key to the recipe’s signature flavor. You’ll use both the peppers and some of the juice from the jar to add acidity and spice.

Italian Seasoning

A good Italian seasoning blend provides the perfect balance of herbs like oregano, basil, and thyme. A homemade mix works wonderfully too!

Beef Broth

This adds depth and richness to the cooking liquid, which doubles as an au jus for dipping.

Garlic and Onion

Freshly minced garlic and diced onion build the aromatic base for the slow-cooked beef.

Rolls or Hoagie Buns

Look for sturdy rolls that can hold up to the juicy beef and flavorful jus without falling apart. Hoagie rolls, Italian rolls, or even ciabatta are great choices.

How to Make Slow Cooker Italian Beef Sandwiches

Making these sandwiches is as simple as combining the ingredients and letting the slow cooker work its magic. Follow these steps:

1. Prepare the Ingredients

Trim any excess fat from your beef roast for a leaner result.
Chop your onion and peel and mince the garlic.

2. Layer in the Slow Cooker

Place the beef in the slow cooker.
Add the onion, garlic, Italian seasoning, and a pinch of salt and pepper.
Scatter pepperoncini peppers over the beef and pour in a bit of the pepperoncini juice for extra flavor.
Add enough beef broth to cover the bottom of the slow cooker (about 1-2 cups).

3. Cook the Beef

Cover the slow cooker and cook on low for 8-10 hours or high for 4-5 hours. The beef is ready when it’s fall-apart tender.

4. Shred the Beef

Remove the beef from the slow cooker and shred it with two forks.
Return the shredded beef to the slow cooker and mix it with the juices to keep it moist and flavorful.

5. Assemble the Sandwiches

Lightly toast your rolls for added texture.
Pile them high with shredded beef, a few pepperoncini, and optional toppings like provolone cheese or giardiniera.
Serve with a small bowl of au jus for dipping, if desired.

Storage Options

Got leftovers? No problem! Here’s how to store and reheat your Italian beef:

Refrigeration

Store the shredded beef and jus in an airtight container in the fridge for up to 4 days.

Freezing

For longer storage, freeze the beef and jus in separate freezer-safe containers or bags. It will stay fresh for up to 3 months.

Reheating

Warm the beef in a saucepan over medium heat with some of the jus to keep it moist. You can also reheat it in the microwave in 30-second intervals.

Variations and Substitutions

One of the best things about these sandwiches is how adaptable they are. Here are some variations to try:

Spicier Version: Add red pepper flakes or swap pepperoncini for banana peppers.
Cheesy Upgrade: Melt slices of provolone or mozzarella on the sandwiches.
Low-Carb Option: Serve the beef over zucchini noodles or cauliflower rice instead of bread.
Vegetarian Twist: Replace the beef with shredded jackfruit and use vegetable broth for a plant-based version.
Extra Veggies: Add sliced bell peppers or mushrooms to the slow cooker for added flavor and texture.

With its rich, savory flavors and effortless preparation, Slow Cooker Italian Beef Sandwiches are destined to become a staple in your recipe rotation. Serve them up for a quick family dinner or wow your guests at your next gathering—either way, they’re sure to impress. Enjoy!
