Pesto Chicken Sandwich with Caramelized Onions and Havarti

Pesto Chicken Sandwich with Caramelized Onions and Havarti

It has been extremely hot here for the last few days and I have been trying to do easy meals that don’t require too much cooking inside the house. I just made homemade pesto sauce and couldn’t wait to use it so I made grilled pesto chicken sandwiches with caramelized onions and Havarti cheese. I served them with a caprese salad, baked fries, and a cold beer–a perfect meal for a hot summer night. My husband did an amazing job grilling the chicken breasts, they were moist, tender, and delicious. Words cannot express how much I loved these sandwiches… the pesto, caramelized onions, and Havarti were a perfect combination of flavors. We had friends over for dinner and not only did they love it but so did all of the kids.

Pesto Chicken Sandwich with Caramelized Onions and Havarti:


  • 4 boneless, skinless chicken breasts, trimmed of fat
  • 3/4 cup of pesto, divided
  • 1 tbsp olive oil
  • 1 sweet yellow onion, sliced
  • 8 slices of Havarti cheese
  • 8 hamburger buns
  • Mayonnaise
  • Lettuce leaves
  • Tomato slices

How to Make Pesto Chicken Sandwich with Caramelized Onions and Havarti

Cut each chicken breast into two pieces. Place chicken between two pieces of wax paper or saran wrap and pound each piece until thin. Place chicken in a large zip lock bag with 1/2 cup of pesto and marinate for at least 2 hours.

Heat olive oil in a skillet over medium heat. Add onion slices and a bit of salt then saute for 15-20 minutes or until caramelized.

While the onions are cooking place chicken breasts on a hot grill and grill for about 5 minutes then flip. Cook additional 2-3 minutes then add cheese and continue to grill for 2-3 minutes or until cheese is melted and juices run clear.
