These big mac smash tacos are 500/10! If you love McDonalds, then you’ll love this recipe as it’s a smash burger on a taco topped with my version of Mac sauce. Every bite you take is heavenly so don’t be afraid to double the recipe as your family won’t be able to get enough.

The best part of this recipe is that it takes exactly 5 minutes on the stove. You press the meat thinly onto a small flour tortilla, lightly oil the pan (or grill) and cook it meat side down for 2-3 minutes until golden and caramelized.

I like to add aged Havarti (or cheddar) onto the meat tortilla once flipped, cover it with a lid until melty, take it off the heat and top it with my favorite toppings and my homemade big mac sauce. This recipe is the perfect addition to your weeknight meal and I know it will be on repeat.

trust me, you’ll want seconds

Prep Time: 10 minutes
Cook Time: 5 minutes
Total Time: 15 minutes


  • 450 grams ground beef, or any ground meat you like
  • pinch of salt and pepper
  • 1 tablespoon avocado oil
  • 5 small flour tortillas

Mac Sauce

  • ¼ cup mayonnaise
  • ¼ cup sour cream
  • ¼ cup plain yogurt
  • 1 tablespoon tomato paste
  • 1 tablespoon honey Dijon mustard
  • 11/2 tablespoons relish, or a whole pickle diced
  • 1 tablespoon pickle juice , optional

Additional Toppings

  • grated or sliced cheese, I like aged Havarti or Cheddar
  • finely chopped lettuce
  • ¼ finely chopped onion


  • Prepare the Mac Sauce by adding all of the ingredients into a measuring cup or mixing bowl and stir together. Set it aside or in the fridge.
    Note: If you don't have/like relish you can finely dice 1 pickle and add some pickle juice into the sauce instead.
  • Take a small pack of ground beef (or ground meat of choice) and divide it into 5 equal portions (about 1/3-1/2 cup of meat). Roll each portion into a ball and set aside.
  • Take a small flour tortilla and one portion of the ground beef. Press the ground meat onto the tortilla making sure you press it flat and into one even and thin layer with your fingers.
  • Add a tiny pinch of salt and pepper on top. Repeat this step for each one and set aside.
  • Heat up a pan on the stove on medium-high heat. Add a touch of avocado oil (or use avocado oil spray) and place the tortilla meat side down.
  • You should hear it sizzle. Let it cook for 2-3 minutes or until golden and caramelized. Flip it over, add the cheese of choice, reduce the heat to medium-low and put a lid on the pan so the cheese melts for another minute or so.
  • Take it off the heat, top with lettuce, finely chopped onions and the Mac sauce. Enjoy!


Use any tortilla you like. Flour tortilla are my favorite for this recipe. 
Any ground meat will work but I like ground beef the most in this recipe.
You can make the mac sauce with JUST mayo or JUST sour cream or JUST yogurt if you want to change it up or lighten it up. I like a combination of all three.

If you don’t like relish, finely dice 1/4 cup of pickles and add it in instead with some pickle juice.

Hi! I'm Sneji. Nice to meet you!

I am more commonly known as “The Modern Nonna” on social media where I create easy home cooked meals with a modern twist. I was born and raised in Sofia, Bulgaria and learned how to cook at the best culinary school in the world – my grandma’s kitchen. I lived in Greece on the Island of Crete with my parents for a while and then moved to Toronto, Canada when I was in grade 5. I started to really cook and experiment with food 11 years ago when I was 21 years old. Everything I currently know is a reflection of some part of my life…
