Preheat the oven to 375°F.
Make the pesto: (You can also use store-bought pesto if preferred ?) In a food processor, blend all ingredients for the pesto, except the olive oil, together until smooth. Then, slowly stream in the olive oil. Add more olive oil if needed to get desired consistency and adjust any seasonings to your preference. Set aside.
2 large bunches fresh basil (~2-3 cups, stems discarded), 1/3 cup pine nuts, 1/3 heaping cup freshly grated Parmesan cheese, 2 Tbsp. fresh lemon juice, 3 cloves garlic, minced, 1/2 tsp. kosher salt, plus more to taste, black pepper, to taste, 1/4 cup olive oil, plus more as needed
Slice chicken in half. Place chicken on a cutting board, cover with plastic wrap and pound with a rolling pin or meat tenderizer tool until 1/2-inch thick.
2 large boneless, skinless chicken breasts, sliced in half and pounded to about 1-inch thick pieces
Combine the flour and seasonings in a shallow bowl and coat the chicken in flour mixture all over.
2 1/2 Tbsp. flour, 1/2 tsp. salt, 1/2 tsp. garlic powder, pinch of pepper
Heat 1 Tbsp. oil over medium high heat in a large oven safe skillet. When the oil begins to shimmer, add the chicken and cook ~3-4 minutes on each side or until golden brown. Remove chicken to a plate.
2 Tbsp. olive oil, divided
Deglaze the pan with a small splash chicken broth to pick up any browned bits and add the remaining tablespoon olive oil.
Over medium heat, cook the onions and cherry tomatoes until the tomatoes begin to pop and blister, about 6-7 minutes. Season with a pinch of salt and pepper. Stir occasionally so the onions don't burn.
1/2 white onion, diced small, 10 oz. cherry or grape tomatoes
Add the broth and heavy cream and bring to a simmer. Stir in the gnocchi and ½ cup of the pesto. Nestle the chicken back into pan. Spoon a bit of the sauce over the chicken. Bake, uncovered, for 10-12 min or until chicken reaches an internal temperature of 165°F.
2/3 cup heavy cream, 1/2 cup chicken broth, 16 oz. package gnocchi
Slice the chicken then return to the pan. Spoon more sauce over the tops of chicken, garnish with black pepper, fresh basil and Parmesan cheese. Serve with remaining pesto or save leftover pesto for another use. Enjoy!
