These gluten-free slow cooker roast beef sandwiches are the ultimate easy comfort food. Tender, flavorful beef simmers all day in a savory gravy, then gets piled high on your favorite gluten-free rolls. Perfect for busy weeknights, game days, or casual family dinners—no one will miss the gluten!
This is one of those recipes that’s so simple, you almost feel like you’re cheating. With just a few ingredients and your trusty slow cooker, you end up with tender, juicy beef that’s perfect for piling high on gluten-free buns. Whether it’s game day, a cozy weeknight dinner, or a Sunday afternoon with the family, these sandwiches hit the spot.
Why I Love This Recipe
There’s something nostalgic and comforting about a roast beef sandwich—especially when the meat is melt-in-your-mouth tender. The best part? This version is completely gluten-free and super low effort. You just season a rump roast, add some gluten-free gravy mix, beef broth, and GF Worcestershire sauce, and let your slow cooker do all the work.
This is also a great “make-ahead” meal. You can cook the roast the day before, shred it, and keep it warm in the slow cooker until we’re ready to eat.
Serving Suggestions
I love serving this roast beef on gluten-free buns or rolls (Canyon Bakehouse and Udi’s are favorites in our house). You can also skip the bread and serve the beef over mashed potatoes or even roasted veggies for a lower-carb option.
To make it a meal:
Add sliced pickles or pepperoncini for a zippy crunch
Top with melted provolone, Swiss, or mozzarella
Pair with a side of coleslaw, chips, or baked fries
Gluten-Free and Flavor-Full
Many store-bought gravy or seasoning packets contain hidden gluten, so it’s important to choose certified gluten-free brown gravy mix and gluten-free Worcestershire sauce. I’ve had great results with Pioneer and McCormick GF gravy mixes.
This recipe is also naturally low in carbs and high in protein—over 40 grams per serving! You get the comfort of a deli-style sandwich with clean, simple ingredients you can trust.
