For my family, this Cheesy Stuffed Bell Pepper Casserole has undoubtedly become one of those recipes that quickly make a house feel like home. A close friend kept telling me how simple and cosy this meal was, so last weekend I really attempted it with my family. It’s everything you love about traditional stuffed peppers, but without all the added work, according to her. She was entirely correct.
Bell peppers can be hit or miss in my home, so I wasn’t sure how everyone would respond. However, as soon as this casserole with its colourful peppers and bubbly, golden cheese came out of the oven, everyone gathered in the kitchen to ask when dinner would be ready..
