Prep the chicken: Pat the chicken dry. Season both sides with 1/2 teaspoon salt, pepper, smoked paprika, and Italian seasoning.
Sear for flavor: Heat the olive oil in a large skillet over medium-high.
Add the chicken and sear 3–4 minutes per side until golden. Remove to a plate; it doesn’t need to be fully cooked yet.
Soften the aromatics: Reduce heat to medium. Add the onion with a pinch of salt.
Cook 3–4 minutes until translucent. Stir in the garlic and cook 30 seconds, just until fragrant.
Build the sauce base: Stir in the tomato paste. Cook 1 minute to caramelize.
Add crushed tomatoes, chicken broth, and red pepper flakes if using. Bring to a gentle simmer.
Simmer the chicken: Nestle the chicken back into the sauce. Reduce heat to medium-low and simmer 6–8 minutes, turning once, until the chicken reaches an internal temperature of 165°F (74°C).
Lighten and enrich: Turn off the heat.
Whisk the Greek yogurt (or light cream cheese) in a small bowl to loosen. Stir a few spoonfuls of hot sauce into it to temper, then swirl the mixture into the pan until smooth and creamy.
Balance and finish: Taste and adjust salt. If the tomatoes are very tangy, stir in a small splash of honey or sugar.
Squeeze in a little lemon for brightness, if you like. Garnish with chopped basil or parsley.
Serve smart: Pair with steamed greens, zucchini noodles, cauliflower rice, or a small portion of whole-grain pasta or brown rice to keep calories low but satisfaction high.
