Gourmet Caprese Pesto Burger Recipe

This Pesto Burger is unlike any other, combining chunky tomato sauce, melty mozzarella, and a rich balsamic glaze for the ultimate caprese flavor! It absolutely screams summertime and adds a gourmet twist to plain ol’ hamburgers.

Pesto Burger

Imagine a perfectly grilled beef burger drizzled with a sweet balsamic reduction.

Served atop a layer of fresh chunky tomato sauce on a toasted ciabatta bun, it’s enough to make your stomach growl and your taste buds swoon.

Add a slice of fresh mozzarella and a spoonful of fresh pesto mayonnaise, and you may just have to pick your tongue up off the floor!

It’s everything you love about a traditional caprese salad, transformed into a hearty pesto mozzarella burger fresh off the grill.

The idea for a caprese burger came to me after trying the Signature Balsamic Vinegar of Modena from the Fresina Pasta Company in Baton Rouge, Louisiana.

Unfortunately, they’ve since retired, but it was truly the best balsamic I have ever tasted.

How good? Let me say this… When I made the reduction for this caprese burger recipe, I couldn’t stop eating it off the spoon. I had to make two batches just to have enough for the burgers!!

If you’re a balsamic fan too, I encourage you to think outside the box — it’s good for so much more than vinaigrettes. I’ve used it as a glaze for meatloaf, a dip for Brussel sprouts, and even in strawberry popsicles!

Ingredient Notes and Substitutions

• Lean Ground Beef – This pesto burger has loads more moisture than usual, so we’re using a 93% lean blend for balance.
  
• Salt & Pepper – We’re keeping the seasonings simple since all the toppings are quite intense. Wait to season the balsamic burger patties until just before grilling.
  
  The salt draws out moisture, so adding it too early will lead to dry burgers.
  
• Balsamic Vinegar – Quality really does make a difference, so try to grab the nicest bottle you can manage!
  
• Chunky Tomato Sauce – This is much closer to a pizza or pasta sauce than the regular canned stuff. Look for a chunky sauce made with San Marzano tomatoes, or make one yourself!
  
• Mozzarella – It must be fresh! Slice it thick — up to ¼-inch — so it becomes nice and gooey while still holding its shape.
  
• Pesto Mayonnaise – Combine your favorite pesto (store-bought or homemade) with olive oil mayonnaise for the best flavor and texture.
  
  You can get away with regular mayo if you don’t want to buy a separate jar, but do not use Miracle Whip!
  
• Ciabatta Buns – Of course, we’re using an Italian bread for this caprese burger recipe! It gets perfectly crispy on the grill, so don’t forget to toast it.
  
  If you’re not a fan, substitute brioche or potato buns, or maybe Kaiser rolls.

Tips and Tricks to Make the Perfect Caprese Burger

• Start with the balsamic reduction.

It takes some time to make and requires constant whisking. Once the vinegar has reduced by half, you’ll need to let it sit for at least 15 minutes to thicken even more and cool.

Good news is that you can make a reduction well ahead of time if needed! Store it in a jar in the fridge, then let it come to room temperature before using.

• Chill the burger patties once formed.

This helps them hold their shape and prevents them from falling apart when flipped on the grill.

Because there isn’t anything mixed into the meat, you can form the patties up to a day ahead of time and leave them covered in the refrigerator.

Just remember to add the salt and pepper before grilling!

• Toast the buns right on the grill.

Ciabatta can be dense and chewy, but it becomes light and crispy when toasted — the perfect contrast to the other textures in this pesto burger.

Keep a close eye on them, as they can burn pretty quickly. A minute or two should do it!

Toasting also prevents the buns from becoming soggy when layered with the tomato sauce and pesto mayonnaise.

Prep Ahead

• Make balsamic glaze
• Slice mozzarella
• Make pesto mayonnaise

What You’ll Need for This Recipe

• Outdoor or Countertop Grill
• Saucepan for making the balsamic reduction
• Mixing Bowls – One for mixing the ground beef and another for the pesto mayonnaise.
• Food Processor – If you’re making the pesto from scratch, just add the mayo and pulse again!

Serving Suggestions

You don’t need much to make a meal out of this pesto mozzarella burger. Meat, veggies, cheese… it’s all right there!

I love pairing it with my roasted vegetable penne pasta or a crunchy summer vegetable salad. Or, toss some zucchini on the grill at the same time as the burgers.

Finish off the meal with a sweet taste of Italy, whether it’s homemade cannoli or a creamy affogato.

Storing and Reheating Balsamic Burger Patties

Transfer grilled burgers to an airtight container once cool, then store in the refrigerator for 3 to 4 days.

All the other components — tomato sauce, pesto mayo, and mozzarella — should be stored separately in the fridge and assembled as needed.

Warm balsamic burger patties in the oven at 350°F or in a skillet on the stove until warmed through. I like to add a splash of water and a lid when using a skillet to help them heat through evenly.
