Argentinian Harbor Charred Pepper Stuffed Vegetables
Bell peppers stuffed with seasoned rice, ground beef and herbs, baked until tender — an Argentine home-kitchen classic.
About This Recipe
Pimientos rellenos, peppers stuffed with a rice and ground beef filling, are a common Argentine home dinner, especially popular for using up a small amount of meat to feed a full family. The filling is seasoned simply with onion, garlic, oregano and paprika, echoing the same herb profile found in chimichurri, then packed into halved peppers and baked until the peppers soften and the filling is fully cooked through. Par-cooking the rice partway before stuffing the peppers is an important step — raw rice packed straight into a pepper often stays undercooked by the time the pepper itself is tender, leaving a crunchy, unpleasant center. A splash of stock poured into the baking dish keeps everything moist as it bakes, rather than drying out in the oven. Finished with a scattering of parsley, this makes a satisfying, complete dinner in one dish, with leftovers that reheat well the next day.

Par-cook the rice
Boil rice in salted water for 8 minutes until partway cooked but still firm. Drain and set aside.
Fully raw rice often stays undercooked inside the pepper — par-cooking first avoids a crunchy center.

Pro Tips
- →
Par-cook the rice before stuffing — this is the single most important step to avoid an undercooked center.
- →
Choose peppers that can stand upright or nestle closely together in the dish so the filling doesn't spill out.
- →
Baste the peppers with the pan juices halfway through baking to keep the tops from drying out.
Variations
- •
Vegetarian: replace the beef with a mix of black beans and extra rice, keeping the same seasoning.
- •
Add cheese: top with shredded mozzarella in the last 10 minutes of baking for a melty finish.
- •
Spicier: add a pinch of chili flakes to the filling.
Storage
Refrigerate in a sealed container up to 4 days. Reheat covered in a 180C oven for 15-20 minutes, or in the microwave with a splash of water, until warmed through.
