Ok, now raise your hand if you get tired of making the same ol’ chicken recipes over and over again.

Yet many times, chicken dishes can come across as bland or dry.

Well, today I’m introducing a clever way to prepare chicken that will excite the whole family… Cheesy Spinach Stuffed Chicken.

Ingredients You Need

  • Chicken Breasts – large chicken breast works best so there is plenty of room to stuff them
  • Fontina Cheese – or any creamy cheese like cream cheese, mozzarella cheese, or even feta cheese
  • Frozen Chopped Spinach – or fresh baby spinach chopped in small pieces
  • Roasted Red Peppers – or opt for sun-dried tomatoes
  • Shaved Onion – or diced into small squares
  • Garlic – for added flavor and aroma
  • Smoked Paprika – for a slight kick and smoky flavor!
  • Olive Oil – to drizzle on chicken
  • Salt & Pepper – to taste

Pro Tip: For a bit of added heat, add a sprinkle of red pepper flakes on top!

How To Make Spinach Stuffed Chicken Breast

Preheat the oven to 350 degrees F. Line a rimmed baking sheet with parchment paper. Lay the chicken breasts flat on the baking sheet. Starting from one side, use a sharp knife to cut a deep slit (or pocket) into each chicken breast, parallel to the baking sheet, leaving three sides intact. Try to make the cut even so the attached edges are all about 1/2 inch thick.

Squeeze as much moisture out of the spinach as possible. Then, mix the spinach, shredded cheese, red peppers, shaved onion, garlic, paprika, and 1/4 teaspoon salt together in a mixing bowl.

Stuff the mixture evenly into the chicken breasts, turning them upright, so the stuffing is facing up. Drizzle each breast with olive oil and sprinkle generously with salt and pepper.

Tips & Tricks

  • You can use fresh spinach if that is what you have on hand!
  • To be sure that the chicken is thoroughly cooked through, use a meat thermometer to check that the temperature in the thickest part of the chicken has reached 165 F!
  • Switch up the seasonings! I added garlic powder and paprika but other additional spices would be delicious like thyme and basil, or even Italian seasoning!

Frequently Asked Questions

What’s the best way to stuff chicken?

The best method for stuffing chicken depends on the type of chicken you buy! If using bone-in chicken, I would suggest only stuffing fillings under the skin.

If you are using boneless skinless chicken breasts or thighs, lay them flat on a cutting board. Then cut a pocket parallel to the cutting board, that remains connected on three sides.

Now you can either stuff the chicken and lock the fillings in, by closing the chicken with a toothpick. Or you can stuff the chicken and turn it upward, almost like a bowl, so the fillings are on top.

This second method is my favorite, because the filling is on display and the chicken can cook in a shorter amount of time!

How do I cook stuffed chicken breast?

You can pan-fry stuffed chicken in a skillet or grill it if you would like! The best and easiest way to cook spinach stuffed chicken breast is to bake it. This will allow the filling to melt and mingle, without running out of the chicken breast. Bake the chicken at 350 degrees, for 20-25 minutes. This allows plenty of time for the chicken to fully cook and the fillings to heat all the way to the middle.

How should I store leftover stuffed chicken breast?

Store any leftover stuffed chicken breast in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave and serve!
