Big Mac Tacos on the Traeger Flatrock | Heath Riles BBQ

If you’re on social media, chances are, you’ve seen the viral Big Mac Taco trend. I added my own flair to this fad, taking it up a notch. I added a homemade sauce, fresh garnishes, and cooked the recipe on one of my favorite flat top grills. A dash of Heath Riles BBQ Beef Rub gave the taco meat a little Tex-Mex flair. Feel free to change up the toppings to fit your individual taste. 

The Ingredients

With just a few simple ingredients, you’ll have a meal fit for a king! You may already have some of these components in your kitchen. Here’s what you need to add to your shopping list. 

Tortillas. Tortillas are the glue that holds this recipe together. I used small white corn tortillas, which fried to the perfect crisp on the Traeger Flatrock Flat Top Grill. Feel free to substitute with yellow corn or flour tortillas. 

Ground beef. I crafted the Big Mac Taco patties out of 80/20 ground beef. There are plenty of meat-to-fat ratios, but this combination is a winner. It creates tacos with plenty of flavor that aren’t overly greasy. 

Heath Riles BBQ Beef Rub. This tasty rub gave the meat an exciting flavor profile without overpowering the meat’s natural flavors. This blend contains a mix of chili powder, garlic, salt, pepper, and paprika. It’s great on beef, but you can also use it on chicken or pork. 

Cheddar cheese. I kept my cheese simple by using shredded cheddar. I recommend using freshly shredded cheese whenever possible. It doesn’t contain any waxy fillers and melts like a charm! 

All American Burger Sauce. If you cook a lot of burgers, you’ll want to keep a batch of my All American Burger Sauce on hand. This mix of ketchup, mustard, and mayo creates a classic sauce that elevates burgers, salads, and Big Mac Tacos.

Toppings. To garnish the Big Mac Tacos, I added a little shredded lettuce and diced onion. Simple, yet effective!

The Smoker Setup

Here’s the main equipment I used for this recipe. More of my grilling favorites can be found in the Equipment and Tools section. 

• Flat Top Grill. I cooked these mouth-watering Cheeseburger Hoagies on the Traeger Flatrock Flat Top Grill. I love using this setup for quesadillas, tacos, and more!  Pro Tip: Be sure to “season” your grill before using it! This step creates a slick, non-stick surface.

Cooking with a flat top is easy, especially when you know how to clean it! Check out the video to see my process for cleaning your Traeger Flatrock Flat Top Grill without much elbow grease.

The Process for Making Big Mac Tacos

You’ll find an in-depth demonstration of this recipe in the video and recipe card. For now, here’s the Clifs-notes version of how these drool-worthy Big Mac Tacos came together. 

1. Fire up the grill. I fired up the Traeger Flatrock Flat Top Grill and greased the griddle with a dollop of Bacon Up Bacon Grease. 
2. Form the burgers. To form the Big Mac Tacos, I laid a tortilla on the cutting board and placed a meat patty over the top. Using my hands, I smashed the meat into the tortilla until it formed a thin layer that covered the entire surface. 
3. Make the All American Burger Sauce. In a small mixing bowl, I combined diced pickles, mayonnaise, mustard, ketchup, Bear & Burtons W Sauce, and a sprinkle of Heath Riles BBQ Beef Rub until homogenous.
4. Add seasoning. I sprinkled Heath Riles BBQ Beef Rub over the Big Mac Tacos to add a burst of flavor. You can go heavy-handed with this seasoning because you aren’t seasoning both sides. 
5. Make the Big Mac Tacos. I laid the tortillas, meat-side down, on the Traeger Flatrock Flat Top Grill and gently pressed them down. I let each Big Mac Taco sear until golden, then flipped it. 
6. Add cheese. I sprinkled the Big Mac Tacos with shredded cheddar cheese and let the tacos go until the cheese was semi-melted. Be sure to watch the video to see my hack for getting the gooiest cheese ever! 
7. Assemble the Big Mac Tacos. I removed the Big Mac Tacos from the Traeger Flatrock Flat Top Grill and placed them on a Heath Riles BBQ Butcher Paper lined baking tray. To assemble the tacos, I drizzled a spoonful of All American Burger Sauce over the top, followed by a little onion, and shredded lettuce. Now that’s a taco! The only thing left is to fold the taco in half and dig in! 

The Results

The Big Mac Tacos came off the Traeger Flatrock Flat Top Grill crisp, hearty, and full of BBQ flavor. The creamy, cool All American Burger Sauce complemented the seasoned beef perfectly. This is one recipe no one will forget!
