If you are looking for a fun and new way to serve up a chuck roast – you have come to the right place! The delicious flavors of Tex-Mex meshed with a the concept of the classic French dip sandwich are going to make you so very hungry! This Cowboy Beef Dip sandwich was a total success in my house and I am sure it will be in yours too!

For this recipe you will need a slow cooker large enough for your roast to not touch the sides. At least a 6qt size will most likely suffice. When I put the beef ingredients into the crock – I put the roast in first and then spread the rest over the top of the roast, so that the flavors would seep down into the meat while its slow cooking. You really want to get the onion into very small pieces as best you can. You want them to almost melt into the meat, along with the garlic.

This recipe does have some serious kick but it is not overpowering. You really get the flavors of the jalapenos in the slow cooked meat and the nacho cheese. If you need to tone it down at all, I would suggest adding something like sour cream to the sandwich. But I do not recommend omitting the jalapenos as it would complete change the flavor profile of the dish.

These sandwiches are very filling and hearty – so you may not need a side dish. But if you do, I would suggest a fry of some sort – as they will be so super yum dipped in the nacho cheese too! It was also be great with my Beer Battered Onion Rings. If you wanted to make sure you get your veggies in there I would suggest some roasted broccoli and/or cauliflower – which would also be great with the nacho cheese dip!
