How to Make Chicken Wellington with Rosemary Pesto

Orange and lemon slices on a cutting board with stick of butter.

Prep the Chicken:
Slice the orange and lemon. Place chicken breasts on a large piece of foil. Squeeze the juice of the lemon and orange over the chicken. Season with Out Grilling SPG Seasoning and top with a pats of butter.

Cook the Chicken:
Fold the foil edges to seal the packet and grill or bake the chicken for about 20 minutes. Carefully open the packet and transfer the chicken to the grill for another 5–10 minutes, just to get some nice sear marks. Remove from heat and let cool slightly.

Wrap in Puff Pastry:
Unfold the puff pastry and trim to fit each chicken breast. Make slits along both sides of the puff pastry sheet, leaving the center intact for the chicken. Place a chicken breast in the center and spoon rosemary pesto over the top. Fold the pastry strips over the chicken, alternating sides until it’s fully wrapped.

Recipe Notes

Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a 350° oven for best results.
Variations: Mushroom Duxelles (a mushroom mixture with shallots and herbs) can be spread over the chicken in place of the pesto. Make beef Wellington, using beef tenderloin.
Shortcut: Use any store-bought or basil pesto if you’re short on time, but the rosemary version really takes it to the next level.
