The Cooking Process Explained

Here’s the beauty of the slow cooker: you can throw in the ingredients in the morning and return home to a house filled with enticing aromas, not to mention an effortless dinner. You’ll start by searing a juicy beef chuck roast for that delicious, browned flavor. Then, it’s just a matter of layering and letting the slow cooker do its magic. With the right spices, garlic, and a medley of mushrooms, you’ll be rewarded with a dish that’s bursting with umami.

What You’ll Need

For the Beef & Jus:

• 1 tablespoon vegetable oil
• 3 to 4 pounds beef chuck roast
• 1½ teaspoons kosher salt
• 1 teaspoon ground black pepper
• 2½ cups water
• 1 cup low-sodium beef broth
• 1 tablespoon beef bouillon paste or powder
• 1 bay leaf
• 2 packets dry onion soup mix
• ½ teaspoon dried thyme
• ½ teaspoon dried rosemary
• 4 to 6 garlic cloves, minced or lightly crushed
• 8 to 12 ounces mushrooms, sliced

For the Sandwiches:

• 6 to 8 crusty sandwich rolls
• ½ cup butter, softened (optional)
• ½ teaspoon garlic powder (optional)
• 16 ounces sliced provolone, mozzarella, or Monterey Jack cheese
• Prepared horseradish sauce

Feel free to mix and match cheeses according to what your taste buds fancy—mozzarella for melty goodness or provolone for that slight tang.

Directions to Follow

1. Start by heating a large skillet over medium-high heat. As it heats, pat the beef dry and season all sides with kosher salt.
2. Add the vegetable oil to the hot skillet, and sear the roast for 1 to 2 minutes on each side until it achieves a rich, golden-brown color that adds depth to the flavor.
3. Once seared, transfer the beef to your slow cooker, and don’t forget to give it a sprinkle of black pepper.
4. In the same skillet, pour in the water, beef broth, and bouillon, scraping up those delicious browned bits from the bottom—this is liquid gold! Pour this mixture over the beef.
5. Nestle the bay leaf, minced garlic, and sliced mushrooms around the roast. Sprinkle the onion soup mix over it all, letting some fall into the juicy pool below, and then finish by adding thyme and rosemary.
6. Cover and let this simmer on LOW for 8 to 10 hours, which will make your house smell divine, or if you’re short on time, cook on HIGH for 1 hour and then switch to LOW for the remainder.
7. When ready, transfer the roast to a cutting board. Let it rest for a few minutes before slicing it against the grain into thin pieces. This ensures each bite is tender.
8. Preheat your broiler and lay out the rolls cut-side up on a baking sheet. If you’re feeling fancy, mix butter with garlic powder and spread it on the rolls. Broil until lightly golden, then flip to crisp the outside briefly before returning, cut-side up, to add cheese on top. Broil until the cheese is melt-y and gooey.
9. Smear horseradish sauce over the cheese, add your sliced beef and mushrooms, and close up those sandwiches. Serve them hot with bowls of the savory cooking jus for dipping—heavenly!

Creative Ideas for Plating

When it comes to serving, presentation makes a difference! Try pairing these sandwiches with crispy sweet potato fries or a fresh arugula salad drizzled with a tangy vinaigrette. You could also throw in some pickles on the side for a bit of crunch. And don’t forget about those little bowls of jus for dipping! Watching your guests’ faces light up as they dunk their sandwiches is a joy all on its own.

Keeping Leftovers Fresh

If by some chance you have leftovers (I wouldn’t bet on it!), let the beef cool completely before putting it in an airtight container. It’ll keep in the fridge for about 3 to 4 days. For longer storage, you can freeze the sliced beef and the broth in separate airtight containers for up to 3 months. Just remember to thaw in the fridge before reheating.

Practical Cooking Tips

• Searing is Key: Take the time to sear your roast! It adds a layer of flavor that takes your dish from good to unforgettable.
• Flavor Boosters: If you’re feeling adventurous, add some sliced jalapeños or a splash of Worcestershire sauce for extra depth.
• Slow Cooking: The longer you let it slow cook, the more tender and flavorful the beef becomes. This magic takes time, so plan accordingly!

Creative Twists

Feel free to put your own spin on these sandwiches! Swap out the beef for turkey or even a plant-based protein if you’re looking for a lighter option. Want to go regional? Try using a different cheese or add toppings like sautéed peppers or onions. The great thing about this recipe is how adaptable it is!
