# Components:
→ Poultry
01 - 4 boneless, skinless chicken breasts (approximately 700 grams)
02 - 1 teaspoon salt
03 - 1/2 teaspoon black pepper
04 - 1/2 teaspoon dried Italian herbs
05 - 2 tablespoons olive oil
→ Vegetables
06 - 1 small butternut squash, peeled and cut into 1/2-inch cubes (approximately 2 cups)
07 - 2 cups baby spinach
08 - 1 cup sliced cremini or button mushrooms
09 - 1 small red onion, thinly sliced
10 - 1 cup halved cherry tomatoes
11 - 1/2 cup sun-dried tomatoes packed in oil, drained and sliced
→ Sauce Components
12 - 3 cloves garlic, minced
13 - 1 cup low-sodium chicken broth
14 - 1 cup heavy cream
15 - 1/2 cup grated Parmesan cheese
16 - 1 teaspoon Dijon mustard
17 - 1/4 teaspoon red pepper flakes (optional)
# Method:
01 - Pat chicken breasts dry. Season both sides generously with salt, black pepper, and dried Italian herbs.
02 - Heat olive oil in a large, deep skillet or Dutch oven over medium-high heat. Sear the seasoned chicken breasts for 3 to 4 minutes per side until a golden-brown crust forms. Remove the chicken to a separate plate; it will finish cooking later.
03 - In the same skillet, add the cubed butternut squash and sauté for 4 minutes. Add the sliced red onion and mushrooms; cook for an additional 3 minutes, stirring occasionally, until softened.
04 - Stir in the minced garlic and cook for 1 minute until fragrant, ensuring it does not burn.
05 - Add the sliced sun-dried tomatoes, halved cherry tomatoes, and low-sodium chicken broth to the skillet. Bring the mixture to a simmer and cook for 5 minutes, allowing the squash to begin softening.
06 - Reduce the heat to medium-low. Stir in the heavy cream, grated Parmesan cheese, and Dijon mustard until well combined. Return the seared chicken breasts to the skillet, nestling them into the sauce and vegetables.
07 - Cover the skillet and simmer gently for 12 to 15 minutes, or until the chicken is cooked through (internal temperature reaching 165°F or 74°C) and the butternut squash is tender.
08 - Stir in the baby spinach and red pepper flakes (if using). Continue to simmer just until the spinach has wilted. Taste and adjust seasoning as necessary.
09 - Serve the One-Pot Creamy Tuscan Chicken hot, spooning the rich sauce and vegetables over the tender chicken.
