Slow Cooker Cheese Steak Sandwiches with Poblanos + Portabella Mushrooms

Next up on the blog:  Slow Cooker Cheese Steak Sandwiches with Poblanos + Portabellas.  These slow cooker sammies are a snap to make and, hey, just look at that melty cheesy goodness — just look at it!  They’re also loaded with spicy poblano peppers, portabella mushrooms, and caramelized onions.

We use Italian Seasoned Steak Rolls from the Fareway Bakery when making these steak sandwiches, but any good steak roll will do!


This meal is another staple for me and Trevor; he’s actually the one who makes them the most often.  Have I ever told you guys that Trevor makes supper for me every night when I work till 7?  It’s so so nice to come home to yummy meals like this after a ten hour work day.  What can I say?  He’s a winner!

Other than the “locally sourced” bakery rolls, these sandwiches aren’t really local or seasonal by any means.  But hey, sometimes you just need a warm, toasty, cheesy, carb-loaded sandwich in the middle of winter.  Right?  Right.

  • 3 TB red wine
  • 2 TB soy sauce
  • 2 TB Worcestershire sauce
  • 2 TB grainy mustard

  2. Slice the yellow onion and layer ¼ of the onion in the bottom of a slow cooker. Reserve the remaining onion and refrigerate. Add the chuck roast to the slow cooker.

  4. Once the roast is ready, heat a skillet over medium heat with a tablespoon of olive oil. Add in peppers, reserved onion, and mushrooms and season with salt. Sauté until tender, around 15 minutes.
  5. On a large baking sheet, arrange steak rolls and top with chuck roast, sautéed veggies, and provolone. Broil on high heat until cheese is melted.
