1teaspoondried oregano
1/8teaspoonblack pepper
1largebay leaf
Instructions
Combine the water, beef base, bay leaf, oregano, black pepper, and garlic in a medium saucepan and bring to a boil. Boil for 5 to 7 minutes, until the liquid reduces by about a third. Taste and adjust the salt now, before the beef goes in. It should taste slightly too strong on its own.
Meanwhile, preheat the broiler to low. Split the hoagie rolls, arrange cut side up on a baking sheet, brush with melted butter, and broil for 2 to 3 minutes until golden.
Dip the roast beef into the hot broth for 1 to 2 minutes, just until heated through. Lift it out with tongs, let the excess drip off, and pile onto the toasted rolls.
Top with provolone and broil for 1 to 2 minutes to melt the cheese.
Finish with pepperoncini and serve immediately with a small bowl of the warm broth for dipping.
Notes
Beef base ratio: The jar directions call for 1 teaspoon per cup of water. This recipe uses 5 teaspoons for 3 cups on purpose, to get a broth concentrated enough to flavor the meat.
Season before the beef goes in. Once the beef has soaked, added salt only seasons the liquid. Taste and adjust while the pot is still on the stove.
No beef base? Substitute 4 cups of boxed beef stock and reduce it by a third to a half on the stove to concentrate the flavor.
Slice thickness matters most. Ask the deli for the thinnest setting. Thick slices won't absorb the broth.
Choose a sturdy roll. Soft grocery-store hoagies fall apart when dipped. A crusty French roll holds up much better.
Don't simmer the beef. More than 2 minutes in boiling liquid turns deli slices gray and stringy.
Cheese swaps: Swiss and fresh mozzarella both work well. Avoid pre-shredded, which turns greasy under the broiler.
Pepper options: Drained hot giardiniera is the traditional Chicago topping. Roasted red peppers add sweetness instead of heat.
Storage: Keep the beef in the broth in the fridge for up to 3 days and store rolls separately. Reheat the beef and broth together, then toast fresh rolls.
Feeding a crowd: Hold the beef and broth in a slow cooker set to warm for up to 2 hours and let guests build their own.
