When I heard the theme for this week's Sunday Supper recipe round up I knew I was all in with both boots and my hat, too. Cowboy cooking is near and dear to my heart and I'm a classic Texan -- I'll take the beef, thanks.
This slow cooker steak sandwiches recipe is absolutely perfect for Sunday supper because you toss everything in the slow cooker before you get ready for church then when you get home you take your little nap and by late afternoon your house smells amazing and your dinner is done.
Ta Da.
🧾 Ingredients
For this recipe you'll need: cornmeal sandwich buns or other sandwich rolls, bottom round roast, salt, pepper, ground cumin, smoked paprika, garlic powder, beer, chipotle aioli, smoked cheddar, onions, poblano, oil
So, I made special cornmeal sandwich buns for this recipe because I wanted the entire thing to really just scream Texas Flavors, y'all.
The cornmeal gives the rolls a little extra texture and a sweet-nutty-wholesome flavor that I love.
You can use sourdough baguettes or hoagie rolls from the deli if you want. Onion rolls would be great, too. Just not as good as the cornmeal sandwich rolls.
By the way - these spicy fried shrimp po' boy sandwiches are good on these rolls, too!

The other homemade component of this gorgeous, cowboy approved sandwich is the chipotle aioli.
Now, before you think that I've gone all fancy on you I have to tell you that aioli is just French mayonnaise - and since this has chipotle in it I guess it isn't even very French.
You can get the same effect by mixing mashed chipotle in adobo with a good mayonnaise but... again... it won't be quite as good.

Make It Yours - Tips for Yummy Variations
This is one slow cooker steak recipe you won't want to forget but don't be afraid to change it up to make it your own.
- Substitute candied jalapenos for the poblano

- Try these cheddar cracked pepper rolls instead of the cornmeal rolls
- Use onion rings instead of blackened onions
- Try pepper jack or provolone instead of the smoked Cheddar

- You can never ever go wrong with sauteed mushrooms
- Add crispy bacon
📞 The last word
When I was little cowboy boots were the only thing that fit me. My mom told me that they could take me into a shoe store and try on every pair of shoes but they all hurt until I got cowboy boots on my feet.
Now, I'm not going to say that I wanted cowboy boots exactly but I will say that I don't tend to settle for things I don't want... rarely have.
I'll also say that I love shoes so if they were trying to get me into those boring white toddler high tops it's no wonder that the black and red cowboy boots were the only ones that fit, yeah?
Do ya'll miss window shopping? I mean, the whole going downtown and strolling the street, looking in all of the shops with the big windows for displaying everything?
The shoe store we went to had a portico with tiny white and black tiles and a long display window on each side. The effect was walking down a hall, flanked by shoes of all kinds, until you got to the door.
Now, in Dallas, window shopping in the summer could be deadly, especially since back then we dressed up to shop - dresses, gloves, hats...
I remember that walking under the portico caused the temperature to drop significantly. You could feel the heat dissipating... but opening the glass doors of the shop resulted in a blast of arctic air that lured you in and frosted your lungs with every breath.
Plus there were always those gum machines. You stuck a penny in and turned the crank and held your hand until the opening until four or five pieces tumbled out. My hands were tiny and I can remember that I almost always had to scoop one up off the floor before my mom could see that it had dropped.
Waste not, want not - right?
You will not want to waste one bite of these glorious pot roast sandwiches. The layers of flavor just keep coming in waves.
Just don't tell anyone how dang easy it is or you'll be making them every day.
On second thought... that might not be a bad thing, huh?

Those cornmeal sandwich buns look and sound spectacular! As does the French aioli topping your steak sandwiches...I trust that you do or did have quite the collection of cowboy boots. P.s. Looks like shopping was quite the affair in Dallas =)
Marye Audet
LOL! I don't wear cowboy boots but my husband has enough for both of us! 😉 Shopping was... It's not so much like that anymore.
Cindy
