Chicken Marengo is a French-inspired recipe with juicy pan-seared chicken breasts topped with tomatoes and mushrooms. It's saucy, a little spicy, and a whole lot of delicious!
Prep the chicken. Season chicken breasts with cayenne pepper, salt, and black pepper on all sides.
Cook the chicken. Heat 1 tablespoon olive oil over medium heat in a nonstick heavy-bottomed skillet. Add the chicken to the hot oil and cook until the edges are opaque, about 10 minutes. Flip to the other side, cover the pan, lower the heat, and cook for another 8 to 10 minutes, or until done. Then, set them aside.
Sauté. In the meantime, heat 2 tablespoons olive oil over medium-high heat in a large skillet. Add onions and cook for 3 minutes. Stir in garlic and continue to cook for 20 to 30 seconds, or until fragrant.
Make the sauce. Add tomatoes and chicken broth; season with salt and pepper and bring to a boil. Lower to a simmer, cover the pot, and continue to cook for 15 minutes.
Add mushrooms. Remove the lid and add the sliced mushrooms.
Thicken the sauce. Add the flour and stir until completely combined. Cover with the lid and continue to cook for 5 more minutes to thicken.
Finish it up. Stir in basil and parsley, and take the pot off the heat. Taste for seasonings and adjust accordingly.
Serve. Transfer the prepared chicken breasts to a serving plate. Top the chicken with the prepared sauce, and serve.
