Is Costco Stuffed Peppers Good?
The Costco Stuffed Bell Peppers is simply a perfect choice if you want delicious stuffed peppers without making them from scratch. If you like ground beef, tomato sauce, bell peppers, and cheese, then these are a pretty safe and winning bet. They have Parmesan cheese, on top so if you're not a fan of Parmesan, take note, but honestly, you can't really taste strong Parmesan flavor.
After you bake them, you will taste the sweetness of the bell peppers, and the flavors of the ground beef, and the seasoning together. If you love cheese on top, you can add more cheddar or Parmesan on top before baking and you will get a super delicious mixture between melted cheese and ground beef.
Costco peppers are absolutely a good choice for ready-made stuffed peppers.
