Variations to Stuffed Peppers 

This versatile recipe is the gift that keeps on giving. If you’re looking to change things up, try one or more of the following ideas!

  • Vegetarian option: Make a vegetarian version by substituting the chicken with tofu or a meat substitute and using vegetable broth instead of chicken broth.
  • Ground meat: Instead of chicken breast, try ground beef, turkey, or pork to make the filling for your stuffed peppers.
  • Spice level: Adjust the spice level by adding or reducing the amount of chili powder or using a spicier pepper like jalapeño.
  • Cheese: Experiment with different types of cheese, such as Monterey Jack, pepper jack, or queso fresco.
  • Salsa: Add a spoonful of your favorite salsa to the filling for extra flavor and moisture.
  • Beans: Mix in some black or pinto beans to the filling for added texture and protein.
  • Grilled or roasted vegetables: Add grilled or roasted vegetables like zucchini, eggplant, or corn to the filling for a delicious and healthy twist.
  • Rice: White rice or even cauliflower rice can be added to the filling to add more flavor and create a hearty filling. If you are looking for a healthy option reach for cauliflower rice. 
  • Different peppers: Try using different types of peppers, such as poblano or Anaheim peppers, instead of bell peppers for a unique flavor.

Tips for Success 

  • Use fresh ingredients: Use fresh peppers, chicken, and vegetables to ensure the best flavor and texture. Fresh ingredients will also cook more evenly and taste better than frozen or canned ingredients.
  • Precook the filling: To ensure that the chicken is cooked through and the vegetables are tender, precook the filling before stuffing the peppers. This will also help to reduce the overall cooking time.
  • Season the filling well: Use plenty of spices and seasonings in the filling, such as chili powder, cumin, garlic, and onion powder, to give it a bold and flavorful taste.
  • Use the right size peppers: Choose peppers that are large enough to hold a good amount of filling but small enough to fit in your baking dish. 
  • Casserole Dish: Use the right size baking dish so the pepper fit nicely and the peppers are not squished together. Just place pepper halves in the dish and then begin to stuff with the filling.
