These Instant Pot French dip sandwiches are made with tender shredded chuck roast, buttery toasted rolls, and melty provolone cheese. The beef cooks in a flavorful broth until it is perfectly tender, and the cooking liquid doubles as a rich au jus for dipping. They are hearty and satisfying sandwiches that feel special yet are still easy enough to make at home.
Let the roast rest at room temperature for 15 minutes before searing.
Add vegetable oil to the Instant Pot and hit the sauté button.
Season roast with the kosher salt, freshly ground pepper to taste, and garlic powder on all sides.
Sear the roast on all sides in the Instant Pot. Remove the seared roast from the Instant Pot and set aside.
Add onions to the pot and sauté just until they start to soften. Add broth and let simmer. Use a wooden spoon to scrape up seared bits from the bottom of the pot as it simmers.
Return the roast to the Instant Pot and add the bay leaf. Close the lid and make sure the pressure release valve is set to the sealing position.
Select the Meat/Stew function and increase the time to 100 minutes.
Allow the Instant Pot to naturally release for 25 minutes, then vent to release any excess pressure.
Remove roast and shred. Strain liquid through a fine mesh strainer if desired and serve warm for dipping sandwiches.
Turn oven to broil and place sandwich rolls on a baking sheet. Spread butter inside the rolls and toast for 2-3 minutes, just until golden brown.
Place meat onto rolls and top with cheese. Return to the broiler and heat just until the cheese has started to melt.
