I’ve always loved classic stuffed peppers, but standing at the counter, carefully stuffing each one, felt like too much work for a busy weeknight. That’s when I had the idea to deconstruct it into a casserole. The moment I pulled my first version from the oven, the smell that filled my kitchen was pure comfort—savory ground beef, sweet bell peppers, and tangy tomato sauce bubbling together under a blanket of melted cheese. Scooping a spoonful into a bowl, I got every component in one bite: the seasoned beef, tender rice, soft peppers, and gooey cheese. It was everything I loved about stuffed peppers, but easier, faster, and somehow even more satisfying.

Ingredients
- 1 lb lean ground beef (90/10 or 93/7)
- 1 cup yellow onion, diced
- 1 cup green bell pepper, diced
- 1 cup red bell pepper, diced
- 3 cloves garlic, minced
- 1 (15 oz) can tomato sauce

- 1 ½ cups cooked white rice (about ½ cup uncooked)

Let’s talk ingredients, because a few choices make this dish sing. Using lean ground beef is key; you don’t want a greasy casserole. The bell peppers—using both green and red—gives a sweeter, more complex flavor than green alone. Don’t skip the red; it makes a huge difference. For the rice, use day-old or cooled rice so it doesn’t turn to mush. The diced tomatoes should be undrained for the right amount of moisture. And that mozzarella and cheddar blend? The mozzarella gives that iconic stretch, while the cheddar adds a sharp, flavorful punch. Trust me on this combo.(See the next page below to continue…)
