- 2 tsp onion powder: Adds a subtle, sweet onion undertone to the cooking liquid.
- 1 tsp garlic powder: Enhances all the savory flavors with its warm, garlicky aroma.
- 1/2 tsp dried rosemary: Imparts a gentle herbal freshness that balances the richness.

How to Make Slow Cooker Shredded Beef Sandwiches with Caramelized Onions and Melty Cheese Recipe
Step 1: Season and Sear the Beef
First, generously season your tri-tip roast all over with Montreal steak seasoning to ensure every bite bursts with flavor. Heat your favorite heavy skillet or cast iron pan with oil over medium-high heat, then sear the beef for 2 to 3 minutes on each side. You want that gorgeous golden-brown crust—this locks in juices and adds a depth of flavor you’ll love down the line.
Step 2: Prepare the Slow Cooker Base
In your slow cooker, whisk together beef broth, Worcestershire sauce, onion powder, garlic powder, and dried rosemary. Place the beautifully seared beef into this aromatic, savory bath and turn it to coat the meat evenly. This mix will slowly infuse into the beef, making every shred deliciously juicy.
Step 3: Slow Cook to Perfection
Cover your slow cooker and let the magic happen by cooking on low for 7 to 8 hours. Patience here is key because by the end of this long, gentle cooking process, your beef will be so tender it practically falls apart under the fork, ready for shredding into tender bits.
Step 4: Shred and Clean the Beef
Once cooked, transfer the beef to a large bowl and shred it using two forks. This is your moment of satisfaction as you see that perfect shred forming. Don’t forget to pick out and discard any excess fat for a cleaner, lighter bite.
Step 5: Strain and Save the Juices
Strain the cooking liquid through a sieve, discarding any solids. Skim off any fat floating on top, but keep the luscious, flavorful juices to serve as a dipping sauce. Trust me, having those juicy drips makes these sandwiches even more addictive.
Step 6: Rehydrate the Shredded Beef
Return the shredded beef to the slow cooker and pour in about half of the strained juices—or just enough to make the meat juicy and moist. The beef will soak up this liquid, ensuring every bite is tender and packed with flavor without being soggy.
Step 7: Assemble and Melt Your Cheese
Slice your hoagie rolls and pile on the warm shredded beef. Add caramelized onions or sautéed mushrooms if you like that extra sweetness and savoriness. Top generously with slices of mozzarella or provolone cheese, then place the sandwiches in the oven or under a broiler for a few minutes until the cheese melts into a gooey, irresistible layer.
How to Serve Slow Cooker Shredded Beef Sandwiches with Caramelized Onions and Melty Cheese Recipe

Garnishes
A handful of fresh chopped parsley or a light sprinkle of cracked black pepper can brighten up these hearty sandwiches. Adding a little fresh arugula or spinach leaf inside the sandwich offers a fresh, peppery contrast to the rich, melty beef and cheese.
Side Dishes
These sandwiches pair wonderfully with crisp dill pickles, crunchy coleslaw, or crispy potato fries. For a lighter touch, a simple green salad or roasted vegetables round out the meal perfectly, balancing the indulgence of the beef and cheese.
Creative Ways to Present
For a fun twist on the classic, serve these sandwiches open-faced with a side of dipping jus. Or create slider-sized versions for parties and gatherings, perfect for sharing. You can even turn the shredded beef into a hearty filling for stuffed bell peppers or quesadillas, expanding this recipe’s delicious potential.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the shredded beef and juices separately in airtight containers in the refrigerator. This keeps the beef moist and flavorful when you ready to enjoy it later. The hoagie rolls are best kept at room temperature to stay soft.
Freezing
This Slow Cooker Shredded Beef Sandwiches with Caramelized Onions and Melty Cheese Recipe freezes beautifully. Freeze the beef and juices in a freezer-safe container or bag for up to 3 months. Defrost overnight in the fridge for best results.
Reheating
Reheat the beef slowly on the stovetop or in the microwave with some reserved juices to keep it moist. Then assemble your sandwich fresh and melt the cheese as you did originally to restore that irresistible, just-made taste.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While tri-tip roast works great, chuck roast or brisket are also excellent choices because they become tender and shred well after slow cooking.
What if I don’t have Montreal steak seasoning?
You can easily make your own blend with salt, black pepper, garlic powder, onion powder, paprika, and a pinch of dried herbs like thyme or rosemary for a similar punch.
How long can I keep the leftover beef in the fridge?
Stored properly in airtight containers, the shredded beef will stay fresh for up to 4 days in the refrigerator.
Can I make the caramelized onions ahead of time?
Yes, caramelized onions can be made a day or two ahead and stored in the fridge. Just reheat gently before adding to your sandwiches.
Is it necessary to sear the beef before slow cooking?
Searing adds wonderful flavor and creates a crust that locks in juices, but if you’re really short on time, you can skip this step—though I highly recommend taking the extra few minutes for the best results.
