    • Italian Beef Sandwiches with Giardiniera

    Ingredients

    Labeled ingredients for Italian Beef Sandwiches with Giardiniera.
    • Beef Roast - I like to use a 3 to 3.5 pound chuck roast or similar cut, whatever looks the best. A chuck roast is a tough cut of meat, perfect for slow braising in the crockpot to get it fall-apart tender! Remove as much fat as you can from the meat with tongs after it has finished cooking.
    • Salt and Pepper - Salt is very important here! This is a large cut of meat so season it generously on all sides.
    • Onion - Onion adds lots of flavor when slow cooked all day. I like to slice it in half moons so I can see the onion pieces in the finished shredded beef.
    • Red Bell Pepper - Adds a pop of color and extra Italian flavor to the beef.
    • Garlic - Lots of fresh minced garlic gives the beef that classic Italian flavor. You can also substitute 1 teaspoon garlic powder or chopped garlic from a jar.
    • Italian Seasoning - Dried herbs give these beef sandwiches their Italian flare! Use an Italian seasoning blend or an equivalent of dried thyme, oregano, and basil.
    • Beef Stock - The work horse in the slow cooker, beef stock turns your beef roast into juicy, tender perfection! Be sure to load up your hoagies with plenty of the dripping shredded beef, that savory juice soaks into the bun for a deliciously messy sandwich. Enjoy with plenty of napkins!
    • Hoagie or Slider Buns - You can use any type of buns to suit your occasion. I like big hoagie buns to soak up all that liquid from the meat. For a party, you could use a pack of Hawaiian buns, slicing the entire thing in half and loading it up with the beef and cheese. Then bake it, add giardiniera and then cut into perfect party sized Italian Beef sliders!
    • Provolone Cheese - The perfect melty Italian cheese, provolone is best, but mozzarella or even slices of white cheddar will work.
    • Giardiniara - A jar of that tangy zesty pickled veggies, Giardiniera makes these shredded Beef Sandwiches Italian! I've chosen to keep the giardiniera as a topping rather than add it to the crock pot so everyone can add the amount they like. I also like to keep it uncooked, adding a crisp cold contrast to the hot tender beef. There are several options when it comes to the type and brand of giardiniera. Some are packed in oil, some are more of a vinegar pickle brine. Personally, I love them all, but find one that you like! If the jarred veggies are in large pieces, just pull some out and give them a rough chop.

    Instructions

    Step 1 - Sear the beef roast before adding it to the crockpot for maximum flavor! Heat a large Dutch oven or skillet over medium heat with olive oil.

    Season the beef roast well on all sides with salt and pepper. Allow it to sear in the hot oil until it turns a deep brown color, about 5 to 6 minutes per side.

    Step 2 - While the beef sears, slice your veggies.

    Sliced red bell pepper, onion and minced garlic on a cutting board with knife.

    Step 3 - Transfer the seared beef to the crockpot and add in the onions and bell pepper.

    Evenly sprinkle with the minced garlic and Italian Seasoning. Add another pinch of salt to season your veggies.

    Step 4 - Add the beef stock and cook on LOW for 8 to 10 hours.

    Step 5 - When the beef is done, use tongs to pull out and discard as much of the fat as possible while shredding the meat.

    Step 6 - To make the sandwiches, preheat the oven to 350°. On a sheet pan, pile your hoagie or slider buns with the beef, including a bit of the liquid, and top with cheese.

    Bake about 4 to 5 minutes until the buns are toasted and the cheese is melted.

    Step 7 - Serve topped with Giardiniera. You can serve it on the side in a bowl so guests can add as much as they like.

    Chef Tip: After searing the beef on the stovetop, add a bit of the beef stock to the hot pot to deglaze it, scraping up all those little brown bits of flavor with a wooden spoon before adding it and the rest of the stock to the slow cooker.

    Variations

    • Dutch Oven Shredded Beef - After searing the beef roast, you can continue to make and cook the entire recipe in your Dutch oven instead of in a crock pot. After searing the roast on the stovetop, add all other ingredients as instructed, COVER, and bake in the oven at 300° F for about 8 hours. Check on your roast after 6 hours to make sure you still have enough liquid and your roast isn't drying out or burning.
    • Spicy Italian Beef - If you want to kick up the heat, serve your Italian Beef with Hot Giardiniera.
    • Kid-Friendly - The peppers and onions in this recipe have been cut large, so if kids don't like them, it's easy to pull out just the beef with tongs. My kids love sandwiches glued together with lots of melty cheese! I've kept the giardiniera as a topping instead of adding it into the crockpot, so everyone can add as much or as little as they like, or none!
    • If you LOVE slow cooked roasts, try my Rich Molasses Braised Beef Roast, it's sweet and savory delicious!

    Equipment

    I used a 6 quart slow cooker for this recipe, while searing the beef first in an enameled cast iron Dutch oven. Any large skillet or soup pot will work for the sear.

    The entire recipe can be made in a Dutch oven if you don't have a crock pot, see instructions above.

    Storage

    • Make Ahead Instructions - The beef roast can be seared and all ingredients added to the crockpot and then kept in the fridge a day in advance of cooking it. Or, the roast can be completely cooked, then cooled and stored in the fridge a day or two in advance and can be reheated in the crockpot. A great option for parties!
    • Leftover Storage - Store leftover shredded beef in an airtight container in the fridge for up to 3 days. As the meat cools, a white layer of fat will form on the top. Just scrape it off with a spoon and discard in the trash. If storing a fully made sandwich, try to eat it the next day. Transform your leftover shredded beef into this delicious Ragu Pasta Bake!
    • Freezer - Leftover Italian beef can be cooled in the fridge first, then frozen for up to 4 months. Thaw overnight and reheat on the stovetop, microwave, or slow cooker.

    Top Tip

    Really take the time to pick through and pull out the fat with tongs as you shred the beef. The fat from the beef is great in the cooking process to get that meat tender and juicy, but getting a fatty bite in your sandwich is really the worst!

    Recipe FAQs

    Can I skip searing the Beef Roast?

    The answer is yes and no! Yes, you can, it will work and your Italian beef sandwiches will still be tender and delicious. But, searing the meat before adding it to the crockpot REALLY adds tremendous flavor! It is an extra 10 minute step, but if you have the time, it's worth it!

    Is this Italian Beef Gluten-Free?

    Yes, the actual Italian Shredded Beef itself is completely gluten-free. Serve on a gluten-free roll.

    Can I add more peppers and onions?

    Yes! If you love the veggies, go ahead and add 1 large onion sliced and 2 bell peppers. They melt down so much in the crockpot all day that a little extra is delicious!

        Hi Rich, the recipe uses 1 quart of beef stock (4 cups). I keep the giardiniera on the side and not in the crockpot but this is up to you!

      Full disclosure - I ate this as leftovers after someone else made this recipe. Even as leftovers: SO good. I warmed up the beef in the microwave and slabbed it on a bun with peppers, cheese, and put it in my toaster oven for a couple minutes and it was delicious!
