A Tex-Mex Twist on the Classic Western Burger
Traditionally, a Western burger recipe—sometimes referred to as a cowboy burger—is all about American flavors. These awesome burgers are often stacked with bacon, barbecue sauce, sharp cheddar cheese, and crunchy onion rings, classic ingredients you might find on this burger if you were to stop by a roadside diner or backyard barbecues.
This version, however, is uniquely different in the fact that while it's still a western-style burger, it brings more of a fresh Tex-Mex spin to the classic concept. Instead of leaning solely on American flavors, I pair fire-roasted poblano peppers with guacamole, pepperjack cheese, and a homemade chipotle lime crema. The result is one of my favorite burgers that still honors the spirit of the cowboy burger while delivering unique texture, flavor, and a spick kick. It's a more nuanced take that still checks all the boxes—beefy, cheesy, smoky, and delicious.
Ingredient Highlights
These ingredients layer smoky, creamy, and spicy flavors to create a burger that's big on taste. For a complete list of ingredient amounts, refer to the recipe card at the bottom of the page.
- Ground beef (80/20 or ground chuck): The fat ensures tenderness while forming a thin patty that won't dry out. Lately, I've been grabbing the pre-made patties from Schweid & Sons because they're pre-formed into 2.5 oz. patties that are the perfect size for a crispy smash burger and are easier to prepare. Good, old-fashioned ground beef from the grocery store also works fine.
- Pepper Jack cheese: This is one of my favorite cheeses to grab at the store. Also, it doesn't hurt that it melts beautifully on the beef patties and adds just the right amount of heat.
- Fire-roasted poblano peppers: Bring mild heat and smoky depth. I'll walk through exactly how to prepare these in the next section. Trust me, it's not as complicated as it looks.
- Pickled red onions: Add acidity and tang to balance the richness. This is one of my all-time favorite toppings, and subbing crispy fried onions for this pickled variety is a no-brainer to add some much-needed acidity to this dish to make the remaining ingredients truly stand out.
- Prepared guacamole or smashed avocado: A creamy, cooling contrast to the bold flavors. I grabbed a pre-made variety for ease this time, but if you have some homemade guacamole in the fridge or want to really impress your guests, you can upgrade this burger by making it from scratch.
- Chipotle Lime Crema: A smoky, citrus-forward sauce made with sour cream, mayo, adobo sauce, and lime. Delicious and straightforward -- I've written a whole blog post on this tasty sauce here.
Step-by-Step Instructions
Step 1: Make the Chipotle Lime Crema
In a small bowl, combine the sour cream, mayonnaise, adobo sauce, lime zest, and lime juice. Add a pinch of salt, then stir until the mixture is completely smooth and well combined. This crema should be tangy, smoky, and slightly spicy—perfect for cutting through the richness of the burger. Cover and refrigerate it until you're ready to build your burgers. You can prepare this a few days ahead of time if you prefer. The flavors will deepen as it chills.
Step 2: Roast the Poblano Peppers
Place your poblano peppers over an open flame, under a broiler, or directly on a hot grill. Roast them until the skins are blackened and blistered all over -- it should only take a few seconds per side. Transfer the peppers to a large bowl and cover with foil, a Seran wrap, or a plate to let them steam for about 5 minutes. Once cooled slightly, scrape off the skins with a knife, remove the stems and seeds, and slice the flesh into long strips. Once that's done, you can set these aside.
Step 3: Make the Smashburger Patties
Divide the ground beef into small portions of 2-3 oz balls (or use pre-made patties, such as the ones I mentioned above), then season with salt and pepper or your favorite savory rub to taste. Place one beef patty on the griddle and immediately press down with a sturdy spatula for about 10 seconds. I've found that placing a sheet of parchment paper between the spatula and the burger is an effective way to prevent the spatula from sticking and tearing the burger. Let it cook for 1–2 minutes until browned, then flip.
Once flipped, quickly add a slice of cheese and cook for 1–2 minutes until the cheese has melted. Take the finished patty off the griddle and repeat as needed; the beauty of a griddle is that you can make several of these at once.
Step 4: Toast the Buns
Lightly butter the cut sides of your hamburger buns. Place them face down on the hot skillet or grill and toast until golden brown. This helps create a sturdy, flavorful base that won't get soggy under your toppings.
Step 5: Assemble the Burgers
To build your burger, start with the bottom bun and spread on a layer of guacamole or smashed avocado. Add a few strips of the fire-roasted poblanos, followed by a generous helping of pickled red onions. Stack two cheese-covered smash burgers on top of the veggies. Drizzle chipotle lime crema over the patties before finishing with the top bun and serve immediately with French fries or onion rings on the side.
Substitutions
If you're looking to tailor this burger to your preferences or dietary needs, consider the following straightforward swaps:
- You can substitute turkey or plant-based patties in place of the ground beef for a leaner or vegetarian-friendly option.
- If you prefer a lighter crema, use plain Greek yogurt instead of sour cream without sacrificing creaminess.
- When you're short on time, don't hesitate to reach for storebought versions of guacamole, pickled onions, or even chipotle sauce -- that's what I did here for both the guacamole and the pickled onions to save some time.
- If you're craving more heat, go ahead and add your favorite hot sauces or some sliced jalapeños.
Variations
If you're feeling adventurous or want to give this Tex-Mex Smashburger your signature spin, try one of these creative twists:
- Swap out the pepper jack for a milder or smokier cheese like Gouda or Monterey Jack if you prefer.
- You can also change up the texture by replacing the pickled red onions with crispy onion rings or fresh onion strings. If you want to save some time, you can buy them pre-made at the store.
- Want to bring this closer to the original Western burger? Besides adding homemade onion rings (or storebought, as I mentioned earlier), add a few strips of bacon and replace the crema with a little bit of tangy BBQ sauce. They will still go great on this burger.
- Hosting a crowd? Turn these into mini slider versions for the perfect party bite. You will need to increase the ingredient amounts to fit the slider rolls.
Recommended Equipment
- Cast iron skillet or griddle: For even heat and crispy burger edges. Having one of these is a non-negotiable for Smashburgers.
- Grill, stove, or open flame: For roasting the poblanos
- Tongs: For managing the poblanos
- Prep Bowls & Measuring Spoons: For gathering your ingredients
- Burger Press or Large Spatula: For smashing the burgers
- Parchment Paper: To make sure the burger patties don't stick to the spatula
- Plate or Pan: for transporting the burgers
- Sharp Knife & Cutting Board: For slicing the poblano
Storing & Reheating
Proper storage and reheating are key to enjoying leftovers without sacrificing flavor or texture. Make sure to store the burger components separately in airtight containers. Cooked burger patties can be refrigerated for up to 3 days; reheat them in a skillet over medium heat to revive their crispy edges and juicy interior. The roasted poblano strips should be stored in the fridge and can be gently warmed before serving. The chipotle lime crema should be kept in a sealed jar or an airtight container in the refrigerator, where it'll stay fresh for up to a week.
For best results, assemble the burgers just before serving. This ensures that the buns stay firm, the toppings are in their best condition, and the cheese stays melty. If you're planning to freeze, only freeze the raw burger patties—place them between sheets of parchment and store in a freezer-safe bag. Cook directly from frozen when ready over high heat.
