The Good Stuff You’ll Need

4 boneless, skinless chicken breasts
2 teaspoons olive oil
Salt and pepper, to taste
1 teaspoon garlic powder
1 teaspoon paprika

For the filling:

1 tablespoon olive oil
2 cloves garlic, minced
1 small onion, finely diced
1 1/2 cups mushrooms, finely chopped (cremini or white work great)
2 cups fresh spinach, roughly chopped
2 tablespoons plain Greek yogurt (or low-fat cream cheese)
Salt and pepper, to taste

Let’s Do This Step-by-Step

Step 1: Prep the Chicken
Preheat your oven to 375°F (190°C). Use a sharp knife to carefully slice a pocket into each chicken breast — don’t cut all the way through. You want a nice deep pocket for stuffing. Pat dry and season both sides of the chicken with salt, pepper, garlic powder, and paprika. Set aside.

Step 2: Make the Mushroom Filling
Heat 1 tablespoon of olive oil in a skillet over medium heat. Add diced onion and sauté for 2–3 minutes until soft. Add garlic and chopped mushrooms and cook until the mushrooms release their moisture and begin to brown, about 5–7 minutes. Stir in the chopped spinach and cook for another 1–2 minutes until wilted. Remove from heat and stir in the Greek yogurt until creamy. Season with salt and pepper to taste.

Step 3: Stuff the Chicken
Divide the mushroom filling evenly and stuff it into the pockets of each chicken breast. You can secure them with toothpicks if needed, but they usually hold just fine if the filling isn’t overstuffed.

Step 4: Sear for Flavor
In the same skillet, heat 2 teaspoons of olive oil over medium-high heat. Sear the stuffed chicken breasts for 2–3 minutes on each side until golden brown. This locks in flavor and gives the outside a delicious crust.

Step 5: Bake Until Perfect
Transfer the chicken breasts to a baking dish or keep them in your oven-safe skillet. Bake for 20–25 minutes, or until the internal temperature reaches 165°F (74°C). Let them rest for a few minutes before slicing.

Serving Suggestions

Serve with a side of roasted veggies, a crisp salad, or mashed cauliflower for a full low-carb meal. A drizzle of balsamic glaze or a squeeze of lemon over the top? Chef’s kiss.

Switch It Up

Swap spinach for kale or arugula if that’s what you have.
Add chopped sun-dried tomatoes or a sprinkle of Parmesan to the filling for extra flavor.
Use turkey breasts instead of chicken if you’re feeling adventurous.

Make-Ahead Tips

You can prep and stuff the chicken up to 24 hours ahead — just keep it covered in the fridge and sear/bake when you’re ready. Leftovers keep well in the fridge for 3 days and reheat nicely in the oven or air fryer.

Questions People Actually Ask

Q: Can I freeze stuffed chicken breasts?
A: Absolutely! Freeze them uncooked (after stuffing) and defrost overnight in the fridge before baking as usual.

Q: What mushrooms are best?
A: Cremini or baby bella mushrooms have the best flavor, but white mushrooms work fine too.

Q: Can I make this dairy-free?
A: Yup! Use a dairy-free yogurt or just skip the yogurt and use a bit of olive oil to bind the filling.
