Trim and season the chicken: Pat the chicken breasts dry. Season both sides with salt, pepper, Italian seasoning, and smoked paprika.
Sear the chicken: Heat olive oil in a large skillet over medium-high heat.
Add chicken and sear 4–5 minutes per side until golden. Transfer to a plate. It’s okay if it’s not cooked through yet.
Sauté aromatics: Reduce heat to medium.
In the same skillet, add garlic and sun-dried tomatoes. Cook 1–2 minutes until fragrant, stirring so the garlic doesn’t burn.
Deglaze and simmer: Pour in chicken broth, scraping up browned bits. Let it bubble for 2–3 minutes to reduce slightly.
Make it creamy: Reduce heat to low.
Whisk in Greek yogurt, Parmesan, and Dijon until smooth. Keep the heat gentle to prevent the yogurt from curdling.
Add greens and finish: Stir in spinach until just wilted. Add lemon juice and taste.
Adjust salt and pepper as needed.
Return chicken to pan: Nestle the chicken into the sauce. Cover and simmer on low 5–8 minutes, or until chicken reaches 165°F (74°C) internal temperature.
Rest and slice: Remove from heat and let the chicken rest 5 minutes. Slice or leave whole for meal prep containers.
Spoon sauce over the top.
Assemble meal prep: Divide chicken and sauce among 4 containers. Add your chosen sides (quinoa, veggies, etc.). Garnish with chopped basil or parsley.
